Health Psychology
Resistance training
(or strength training) exercise that builds muscle mass and conditioning
What is systems theory, and why is it important to the study of health?
Systems theory conceptualizes something as a system governed by many different factors. A change in any level of the system can influence many other levels. This is important to the study of health because it relates to the biopsychosocial model. A change in any level of those can affect one another and also affect health. For example, a diagnosis such as cancer begins with changes in cells, but it can also lead to changes in behavior, health care, and mind.
What is the Alameda County Study, and what does it tell us about health behaviors?
The Alameda County Study was a longitudinal study that surveyed nearly 7000 people living in california. It asked if residents slept between 7-8 hours each night, controlled their wieght, got physical exercise, limited alchohol to fewer than 5 drinks per day, did not smoke, ate breakfast everyday, and limited snacking between meals.The study found that those who engaged in most of these healthful behaviors were healthier. Skipping breakfast and snacking between meals showed the weakest relationships to better health, but the other five behaviors were all very important
How does the typical American diet compare with others around the world?
The American diet has a long way to go before being healthy. Americans are typically over their daily sugar intake everyday. Americans also rely on high calorie fast food, which is very unhealthy and increases the risk of obesity and high cholesterol. The typical American diet is high in calories and low in nutrition. Most Americans barely get their daily fruit and veggies. Due to Americas diversity, the average diet is changing. Race, ethnicity, gender, and age all factor in to what the typical american eats.
What are the US Department of Agriculture (USDA) dietary requirements?
The USDa advocates for a plant based diet with lots of colorful fruits and veggies, seeds, nuts and beans. They emphasize limitng dairy, and limiting sugar to 12 tsps a day. They created the "My PLate" diagram to help people balance their diets.
What does the common-sense model of illness tell us?
The common-sense model of illness sees our health behaviors as based on how we perceive our health. We look to our own experiences, people we trust, how we feel. This is a parallel processing model, meaning everything takes place at once. We process the cognitive representations of illness along with the emotional representations of our health. Representations include what labels, emotions, and beliefs.
Explain how the theory of planned behavior describes health choices, and explain how to effectively change behavior.
The theory of planned behaviro sees health behaviors as a result of our intentions. It inclues values, hope to success and intentions to succeed. It considers attitudes, subjective norms, perceived behavioral control. For example, if someone has a strong attitude about quitting smoking, they have social support, and they believe they can quit and not be dependent on nicotine, they will be more likely to change their behavior. There are also developmental shifts in behavioral change: intention to change is used in older teens whereas willingness to change is more predictive in early adolescence.
What are health-enhancing behaviors?
The things we do that maintain and promote good health, well being and lonegevity. Ccording to Almaeda study the basic behaviors for good health are maintain a healthy weight eat nutriously dont skip breakfast avoid snacking drink in moderation sleep 7-8 hours dont smoke and exercise
What is the transtheoretical model of change?
The transtheoretical model of change sees a change in health as a process, not an event. There are five stages. The first stage, precontemplation, involves no intention to change. The second stage, contemplation, the individual recognizes the behavior is unhealthy, but is still not ready to commit. IN the third, preparation, the indiviudual has moved toward the point of wanting to work on the problem. In the fourth stage, action, they take the step. The fifth stage, maintenance, involves an ongoing effort to make the change last. This stage is reached if the new behavior is continued for six months or more
What are the health disparities in health behaviors?
Many health disparities exist in health behaviors. Women are more likely to engage in less risky behaviors and have regular checkups, whereas men are more likely to exercise. Adolescents are more likely to engage in risky behaviors. Those individuals with a higher socioeconomic status tend to enjoy better health and less disease than those with lower socioeconomic status. In general people with more education are more likely to practice healthful behaviors. They may have learned more about the importance and may have a higher income they can invest in their health. Cis-gender heterosexual people are more likely to practice healthful behaviors such as regular checkups as opposed to LGBTQ individuals. This may be because health care has a predominantly heteronormative framework so LGBTQ individuals may face discrimination stereotypes and stigma.
What is the significance of the waist-to-hip ratio?
The waist to hip ratio is absed on the circumference of your waist and hips and can point to where fat is stored. The risk of poor health increases with a wasit greater than 35 for women and 40 for men. Fat around your middle (central obesity) is more dangerous becaue it indicates fat deposits around internal organs. This can put you at risk for forgetfullness and dementia later in life.
What is the evolutionary significance of weight and fat, and what is stress weight?
Stress weight is belly fat that results from stress. Weight gain in repsonse to stress can be due to a change in eating habits, less physical activity, lower cortisol levels, and poor sleep. People who put weight on in the middle also tend to react poorly to stress.The thrifty gene hypothesis states that humans store fat when food was abundant for times of need when food was scarce. female hormones (estrogen) cause women to carry more weight in the hips thighs legs and butt for more successfull pregnancies. MEn tend to accumulate fat in the abdomen and upper body
How does the health beliefs model predict health behaviors?
The health beliefs model explains health behaviors as actions aimed at getting results. Cognitive assessment depends on the Perceived threat of a problem, including perceived suseptibility and perceived severity, and the belief that taking action will reduce the perceived threat, including Perceived benefits and perceived barriers. Perceived susceptibility is how one sees ones risk associated with the perceived threat. Perceived severity is the perception that there will be serious cpnsequences if the risk becomes reality. Perceived benefits are beliefs about the positive outcomes associated with a behavior in response to a real or perceived threat. Perceived barriers area person's feelings on the obstacles to performing a health action
What region of the brain regulates eating and satiety?
The hypothamlumus controls appetitie energy use and body weight. It adjusts our food intake in relation to our level of physical activity.
Health promotion
activities that promote or maintain good health
Preventive medicine
any efforts to promote and maintain health and offset disease
Safer sex
sexual contact that is respectful, is pleasurable, is freely consented to by both partners, reduces the risk of passing on any infections, reduces the risk of an unintended pregnancy, and is emotionally safe
Clinical trials
studies done in clinical research to determine whether a treatment or drug is effective
Quasi-experimental research
studies that compare groups of participants on one dependent variable but do not use random assignment of participants
incidence
the number of new cases of a disease at a given time
Theory of planned behavior
the theory that sees health behaviors as the result of our intentions, which are shaped by our attitudes, subjective norms, and perceived behavioral control
Common-sense model of illness
the theory that states that our perceptions about our health inform our health behaviors
How can preventive medicine help fight cancer?
Preventive medicine is any efforts to promote and maintain health and offset disease. A memmogram screening is used to screen for breast cancer. It is recommended every 2 years once the age of 50 is reached. Regular screenings, such as a colonoscopy, are recommended after the age of 50 to screen for colon cancer. These may lead to early detection of cancer and help prevent it from spreading. Wearing sunscreen and going to the dermatologist to look for precancerous skin lesions can help prevent skin cancer.
What are the different types of eaters, and what do these eating patterns mean for weight maintenance and mental health?
Restrained eaters constrict their eating to control calories. Emoitional eaters eat in response to negative emotions. External eaters eat in response to food cues. Emotional and external eaters have higher BMIS. People who have trouble regulating emotions, especially anxiet, are more liekly to be emotional eaters and have higher dsiordered eating rates. Emotional eaters relates to depression. external eaters tend to be high in neuroticism. They tend to be impulsive and use counterregulatory eating. This is bad for health and diet. restrained eating can signify body dissatisfaction and may put at risk for eating disorders. Intuitive eaters, eat when they feel hungry and stop eating when they feel full. This is the healtheist eating pattern.
What historical events led to institutional review boards and codes for scientific research?
Any scientist panning a study must gain approval from an institutional review board to ensure the study is ethical. One event that led to this was the Tuskegee experiemnt. In 1932 in Alabama 600 poor African American sharecroppers were asked to participate in this study in exchange for medical care and meals. Only later was it discovered they were studying the effects of untreated syphillis on the body. Participants were never told of this and were denied treatment once it was availabel. Another historical event that led to IRBS occured after World War 2 because German physicians had conducted painful, sometimes deadly experiements on prisoners in concentration camps without their consent.
What is safer sex, and who practices it?
Safer sex is a sexual engagement that is respectful, pleasurable, and freely consented to by both partners, and that reduces the risk of unitended pregnancy or infections. It does not involve the exchange of any blood, semen, or vaginal fluids. It involves open communication and knowing if either is a potential carrier of an STI. A vaccination to protect against HPV and is recomended in children11 to 12 years old.
What is body mass index (BMI), how is it calculated, and what do the results show?
BMI is a measure of body fat based on your height and weight. (weight*703)/(height squared). If your score is 18.5-24.99 you are in the normal rnage. IF you are over 30 you are obese. if you are under 18.5 you are underweight. BMI can misclassify people. It can overestimate the amount og body fat in athletes and it may underestimate body fat in those with less muscle tone. It is less accurate classifying men than women
What are some common barriers to exercise?
Barriers to exercise include lack of time, inconvenience, lack of self motivation and encouragement/support, not enjoying exercise (boring), low confidince in ability, fear of injury, inability to set goals, no safe place
How has the distinction between acute and chronic conditions influenced health care?
Chronicdiseasesarediseasesthatpersisorworsenovertime.Acutedisordershaveanabruptonsetandshortduration.
What experimental controls are necessary in a clinical trial?
Clinical trials are carefully controlled studies to see whether a drug works. It involves a control group that receives a placebo, usually an inert subtance in the same form of the treatment. This is important because simply being treated can affect the mind and symptoms. It is also a blind experiment, wehre patients are unaware of what treatment they are receiving. It is usually a double blind experiment, wehre no one involved knows who is assigned to what experimental condition. This is so a resaearcher does not treat subjects in different groups differently. Experimental protocol is a detailed plan of study, which specifies the experiment, data collection, and sampling methods.
What are some examples of contagious diseases?
Contagious diseases are diseases that spread through the transmission of an infectious agent, sometimes by physical contact between people. Examples include smallpox, typhoid fever, and polio
What individual differences affect weight and eating?
Self control is the baility to control ones desires, emotions, and behaviors. It involves the anterior cingulate cortex in the prefrontal cortex. Those with less self control tend to eat more, or unhealthier foods. Those with higher self control have lower BMIS. self efficacy is the belief in ones ability to succeed or reach a goal. It is related to health goals. Those with high self efficacy are more likely to eat healthier and work towards their goals of a healthier weight or diet. Aggressive people tend to have a more unhealthy diet. Studies have found links between obesity and pessimism. Neuroticism is related to higher bMIS and so is extraversion. Consecnetious people tend to choose health enhancing behaviors
How do cross-sectional and longitudinal studies compare when it comes to testing hypotheses?
Cross-sectional studies collect data from a group(or groups) of people at a specific time. Developmental studies are concerned with how age and developmental stages relate to outcomes. One problem that can arise is cohort effects, which are factors that arise from a group of people that share an experience or lifestyle. For example, younger people may use technology more because it has been a part of their whole lives, where older people may not use it as much. Cross cultural studies can be used to help understand how cultural differences affect health. For example encouraging people to get a vaccine by posing the statement as either a gain or loss can impact culturs differently. Longitudinal studies follow individuals over thei lifespan, determining how they cahnge and grow over time. Prospective studies follow individuals forward through time whereas retrospective studies look back in time and use past data to discover what lead to the present condition. One problem that arises with longitudinal studies is they take a lot of time. Some participants may drop out throughout the study, or pass away, or the researcher may retire before the experiement is complete.
What are deterministic genes and risk genes?
Deterministic Genes cause a disease to develop. For example, there is a deterministic gene for Alzheimers found in a few 100 extended families. It causes familial early onset diabetes. Risk genes increase the likelihood of developing a disease but do not directly cause it. APOE-e4 is a risk gene for alzheimers found in about 25% of cases.
What data does epidemiology provide?
Epidemiology is concerened with measuring health. iIt was first developed to discover the causes of contagious diseases, and now includes other diseases. They look at risk factors of a disease and try to find ways to protect against it. THey measure mortality, the number of deaths due to a specific cause, and morbidity, the frequency of cases in a specific group at a specific time
Why is evidence-based treatment important?
Evidence-based treatment is the conscientious application of current scientific evidence to health realted decision making. It is based on the best research evidence availble, clinical expertise, and patient values and preferences. This allows for greater confidence in success and the best option for the patient being provided to them.
What are the physical, cognitive, and mental health outcomes associated with regular physical activity?
Exercise delays conditions such as high blood pressure, osteoporosis, diabetes, and heart disease, imporves memory, increases seratonin levels. It increases the efficiency of the cardiorespiratory system, strengthens the immune system. It leads to improvement in reaction time, executive functioning, working and short term memory, reduces anxiety, increases positive mood, and increases the quality of life.
What are the health benefits of exercise? How much and what types of exercise are needed to get these benefits?
Exercise delays conditions such as high blood pressure, osteoporosis, diabetes, and heart disease, imporves memory, increases seratonin levels. It increases the efficiency of the cardiorespiratory system, strengthens the immune system. It leads to improvement in reaction time, executive functioning, working and short term memory, reduces anxiety, increases positive mood, and increases the quality of life. The guidelines are 150 minutes cardio ( raises heart rate and strengthens heart and lungs) and 2 or more days of resistance training (building muscle mass and conditioning)
How does where fat is stored affect health outcomes?
Fat around your middle (central obesity) is more dangerous becaue it indicates fat deposits around internal organs. This can put you at risk for forgetfullness and dementia later in life. People who tend to put on wight in the middle tend to react poorly to stress, which can lead to stres weight. Some cytokines produce fever, inflammation, and make disease worse. When abdominal fat triggers this can of cytokines, it can lead to stroke, CVD and diabetes
Is health a fundamental human right?
From a global perspective health is a fundamental human right. Who states that a nation must provide bare necesssities such as education, freedom from discrimination, and freedom to control ones body
Describe the innate and genetic factors that influence our food preferences and patterns of food consumption.
Genetically, we tend to have a predisposition toward sweet and salty food and an aversion to bitter and sour tastes. In adolescents genes have been found to influence preferences for fruits, vegetables, meat or fish, dairy products, and snacks. Eating habits and dietary preferences acquired in childhood last well into adulthood. Twin studies have shown food preferences have a genetic influence and so does neophobia, the fear to try new things. Food preferences begin in the womb. Once a child is born, they pick up on parents aversion to food. Eating dinner late is linked to greater calorie consumption. Eating dinner together, watching less tv, and getting enough sleep cal all lead to healthier eating.
Why are global perspectives and health disparities important?
Global perspectives look at different beliefs, behaviors, societies, and pblic health policies. Explanations that do not take into account context are likely ro fail. A global perspective highlights areas most need in help, such as Somalia. HEalth disparities are differences in overall health, access to quality health care, and health outcomes. Developed countries have a high average standard of living and developing countries have a low level of material well-being anf have less secure political structures and less stable economies. Local health problems become global health problems, both biologically and morally.
What does the field of health psychology encompass, what are its four focal points, and what are its origins?
HEalth psychology is focused on understanding the biological, osychological and social influences on health and illness with aims promoting health and preventing illness and improving health care systems. The missions of health psychology are to promote and maintain health, to prevent and treat illness, to identify the causes of health and illness, and to analyze and improve the health care system.
What is the difference between health behaviors and health habits?
Health behaviors are actions that promote and maintain good health or stand in the way of good health. Positive health behaviors, such as wearing seat belts and using sun screen, increase the chance of good outcome. Negative health behaviors, such as smoking, increase the risk of poor outcome. Abhealth habit is a health behavior that has become part of daily life. For example, if you wear your seatbelt every day as opposed to occasionaly, it is a health habit. Many health habits are deeply ingrained and develop early in life span.
How do health promotion and disease prevention affect health behaviors?
Health behaviors are actions that promote and maontaon good health or stand in the way of good health. Health promotion and disease prevetniont cann affect these behaviors. Health promotions are activities that promote or maintain good health such as eating right and staying physically active. Disease prevention refers to actions that reduce the risk of negative health outcomes, such as regular checkups and not smokng. Health promotion and health disease would increase positive health behaviors, which increase the chance of good outcomes, such as eating balanced meals and exercising regularly.
Aerobic exercise
(or cardio) an activity that raises your heart rate and strengthens the heart and lungs
Food scarcity
(or food insecurity) uncertain or limited access to nutritionally adequate and safe foods
Health disparities
(or health differences between groups) disparities in health that arise from poor health, risk factors for disease, and limited access to health care—especially among those with social, economic, and environmental disadvantages
Developing countries
(or less-developed countries) countries in which the economic and technological advances are emerging or developing
Hypnic myoclonia
(or myoclonic jerks) sudden jerky movements (or "sleep starts") during the first stage of sleep, due to spontaneous activation in the motor areas of the brain
Dependent variables
(or outcome variables) the factors that are observed or measured as possible outcomes of the independent variables
Social genomics
(or social neuroscience) the field that uses complex technologies and methods to examine the genetic, chemical, hormonal, and neural mechanisms of the reciprocal interactions between biological, cognitive, and social levels of analysis
Transtheoretical model of illness
(or stages of change model) the theory that sees a change in health behavior as not an event but a process of five stages that promote readiness for change
What are health enhancing behvaiors
Health enhancing behaviors are the things we do to maintain and promote good health, well-being, and longevity. The Almadea study pointed out certain activities that were health enhancing: mainting a healthy weight, eating nutritious balanced meals, not skipping breakfast, avoiding snacking, not smoking, drinking in moderation, exercising regularly and getting 7 to eight hours of sleep a night. These activities make poor health and disease less likely
Who practices good health habits, and why?
Health habits are a health bahevior that has become a part of our daily life. Many of our health habits are deeply ingrained and develop earliy in the lifespan. Children are more likely to practice healthful behaviors because of parental pressure. Older adults practive healthful bahviors when they are faced witht he reality of age related diseases. In general people with more education sre more likely to practice healthful behaviors. They may have learned more about the importance and may ahve a higher income they can invest in their health. Cisgender heterosexual people are more likely to practice healthful behaviors such as regualr checkups as opposed to LGBTQ individuals. This may be because health care has a predominantly heteronormative framework so LGBTQ individuals may face discrimination stereotypes and stigma.
What kinds of factors influence health behaviors and habits?
?Factors that influence halth behaviors and health habits are health disparities. One health disparitie is gender: women are less likely to engage in risky behavior and more likely to have regular checkups whereas men are more likely to exercise. Age is another: In adolescence all health behaviors decline for both genders. Sociocultural factors suhc as religion and networking sites also influence health behaviors and health habits. For example, some religiong forbid risky behaviors such as drinking and they emphasize good health practices. Another health disparitie is socioeconomic status. A higher income typically relates to better health, less disease and lower mortality. If someone is a member of the LGBTQ+ community, they may face stereotypes, discrimination, and exclusion in the health field.
What is a health value? Where do our health values come from?
A health value is the intrinsic importance we place on health or a health behavior. The more we value good health, the more likely we are to practice health enhancing behaviors. Health values may be imbued with culture. Research found that when health appeals are framed to be consistent with cultural values of health, more people are motivated to engage in health-promoting behaviors.
Why is a lifespan approach essential to understand health and wellness?
A lifespan approach considers how the factors that influence health and illness vary across the human lifespan. This is important because the biopsychosocial factors that influence personal choices or how we cope can change over the course of our lives. For example, now that people in the uNited States sre living longer, infectious diseases used to kill more people, but now it is chronic illnesses. Risky behavior is related to several of the most common causes of death.
What are the World Health Organization (WHO) recommendations for a healthy diet?
According to who a healthy diet is one that maintains or ipmorves health, prtoects against malnutrition, and lowers the risk of chronic disease. For a healthy diet one should: burn as many calories as eat and vice versa, increase consumption of plant based foods, limit intake of fats and oils, sugar, salt and sodium.

What are the different interventions for behavioral change?
There are different interventions for behavioral change. One is psychotherapy. The therapist will get to know the client and can tailor suggestions to the clients need; however, this is expensive. Primary health care is where most people learn of the need to change their health behaviors. Physicians can provide information to help the patient make changes, or can suggest specialists to help. Large organizations such as work places or schools also offer wellness programs;unfortunately, workplace interventions sometimes have low enrollment rates, and their efficacy is still unclear
What are the stages of sleep, and which stages are most important for health?
There are five stages of sleep: 4 non rem and one rem. The first stage involves jerky movements and slow eye movement. The second stage sleep spindles occur. This is though to help the integration of new information into our knowledge base. Our brain is also cleansed by cerebrospinal fluid. Stages 3 and 4 are the deepest stages of sleep These are generally the most restorative. REM sleep appears like wakefulness and the body become more relaxed, to the point of mild paralysis.
What are the major historical influences on medicine and the field of health psychology?
There are many historical influences on medicine and the field of health psychology. IN 460 BCE Hippocrates argued that illness was a result of environment and lifestyle, and came up with the hippocratic oath, which is still used today. Van Leeuwenhoek came up with the germ theory of disease during the Renaissance which attributed disease to microorganisms. IN the 17th century Descartes set apart the mind and body, saying we function like machines and although they are different they are related. Fleming created penicillin and Salk created the polio vaccine. Sigmund Freud united the mind and body in holism in the late 19th century.
What are the statistics regarding food consumption for the average American adult?
Those aged 20-39 vonsume the most fastfood while those over 60 consume the least. Men consumer more food in every category than women. Blacks eat the most chicken, fish, turkey, and pork, while hispanics eat the most beef.
How does incidence differ from prevalence?
Incidence is the number of new cases at a given time while prevalence is the total number of cases at that time. The number of new cases may be declining (incidence), but each new case adds to the total (prevalance). Incidence tells us the risk of contracting a disease while prevalence indicates how widespread the disease is. Lifetime prevalence referes to the proportion of a population that has at some point in their lives had the condition
What are the various ways in which the environment shapes our eating?
Kids can easily pick up on paretns aversion to certain foods. Some parents may not have healthy food available for a child. On the other hand, pressuring a child to eat only healthy foods or lose weight or try new things may backfire becuase eating can become stressful, leading to avoiding it. Overprotective parents who cater to whatever their kids want can lead to super picky eaters. Parents should always encourage children to try new things. When healthy foods are available and the parents eat them kids are more likely to as well. Eating dinner after 8pm can lead to higher calorie increase. Eating dinner as a family can lead to healthier eating.
What is social engineering?
Social engineering uses the environment to shape behavior. Examples of this can be, prohibiting smoking, while offering free water bottle refill stations, and taxing tobacco and soda. Community based interventions can affect large numbers of people, educating and engagin them. The media, social organizations, or door-to-door campaigns can be used. For example, Walk Kansas, a team based program to help people lead a healthier life has had participants five years later who maintained their new levels of activity.
What do twin studies show us?
Twin studies have shown that genetics influence our preferences. Twin studies have found that genes influence preferences for desserts, vegetables, fruits, and preference for high protein foods, and a sensitivity to bitterness. They have also shown that neophobia, the fear of trying new things, is heritable
What are some cutting-edge advances in health psychology?
Some cutting edge advnaces have been made in health psychology. Social genomics aims to understand genetic, chemical, hormonal, and neural mechanisms using complex technologies and methodologies to examine the reciprocal interactions between biological, cognitive, and social levels of analysis. One approach looks at how emotions influence genes. Advances in genetics gave way to the discovery of the DNA model and the human genome. These advances also led to epigentics, the study of gene expression. An understanding of the microbiome, microbes that contain genetic information, has also emerged. THe microbiota-gut-brain axis was discovered and it was found that it is critical for health.
What are some barriers to practicing good health behaviors?
Some negative health behaviors are simply appealing, such as a ice cream sundae. Some people report positive reinforcement from negative health behaviors. Some smokers claim it relaxes them. Many American do not consume a well balanced diet. This can be from the convenience and low cost of fast foods.
What factors influence morbidity and mortality?
Mortality rate is the number of deaths due to a specific cause. Morbidity is the number or frequency of cases of an illness in a specific group at a specific time.
What are the important differences between objective and subjective health?
Objective health is the assessment of health from observable measures. It includes pain, heart rate, blood pressure, and reaction times. Subjective health is how an individual evaluate their own health, such as whenasked "how are you feeling." Subjective measures are often not directly tied to ones actual health status yet are very predicitve of health outcomes.
What is the distinction between apples and pears?

What is the difference between a quasi-experimental design and an experimental design?
an experimental desin involves direct manipulation of variables within carfeully controlled contdition. Quasi-experimental research resembles experimental studies, but does not involve random assignment, nor independent variables that can be controlled. Because of these, the influence of unexamined variables cannot be ruled out and thus cannot make claims of casuality.

What does correlational analysis tell us?
correlation aims to find a linkage between variables. If both variables increase or both decrease, they have a positive relationship. If the variables move in opposite directions they have a negative relationship. Correlation does not prove causation. It helps determine if there is a relationship between variables and how strong that relationship is. The closer the relationship is to the absolute value of one, the stronger the relationship.

What developmental and gender differences are associated with weight?
female hormones (estrogen) cause women to carry more weight in the hips thighs legs and butt for more successfull pregnancies. MEn tend to accumulate fat in the abdomen and upper body Your physique is hsaped by genetics. Early feeding patterns, such as lack of nutrition, can influence weight, so can poor eating habits, especially in adolescence. In midlife metabolism slows down. If these people consume the same amount of calories as before they may increase in weight.

How do health goals motivate us?
health goals define the way we envision our future selfs and they play a big part in motivation behaviors. The more important the health related goal, the more daily behaviors people engage in and the more capable people feel of achieveing the goal in the future. When faced with the need to change behavior, evoking possible selves is linked to self-efficacy and desired outcomes. The more central the goal, the more actively it is pursued, and the omre capable we feel of reaching it.

What is relapse, and how does it influence behavior change?
relapse is returning to a substance or behavior after a period of abstinence. AMrital problems, lonliness, family conflicts, mental health problems, substance abuse, and financial problems can all stand in the way of adherence, which is whether a persons behavior is consistent wiht medical or health advice, stated goals, or a behavioral change. Certain high risk cituations commonly lead to relapse. These situations can be high risk because of immediate determinants, factors that pose the msot danger and highest risk of relaspe, such as physiological or environmental problems, and covert antecedents, which are day to day activities and demands that put someone at risk of relapse. A relapse can cause guilt, which may lead to letting go of the goal. This is the abstinence violation effect, where each lapse makes the next more likely.

What is the biopsychosocial model, and how does it help us understand, diagnose, and treat people's health experiences?
the biopsychosocial model highlights the role of biological characteristics (such as genes)psychological factors (such as stress and health beliefs), and social factors (such as support and cultural influences) in health. It considers the interaction between these three processes. For example, somebody who has few biological risks, has social support, strong coping schools, and accesss to information and treatment may be seen as having optimal health and wellness. IN contrast to this, a child who is malnourished, lives in one or the poorest countries, is an orphan, doesn't have access to treatment, education, food or other resources is vulnerable to every level of the bippsychosocial model. This model helps identify many different factors that contribute to health and helps treat people in ways that will be most beneficial to them
