HDFS 312 EXAM 1
Major changes in the bones
18-24: Bone mass is still building. 25-39: Peak bone mass reached at 30. 40-64 Bone mass begins to decline gradually for men and more sharply for women, especially after menopause. 65-74: Bone mass continues to decline. Risk for fractures increases, especially for women. 75+: Bone mass continues to decline. Risk for fractures increases sharply, especially for women.
Major changes in gender differences (hormones)
18-24: Hormones are fully functioning; fertility is at optimal level. 25-39: Production of major hormones begins to decline, but not noticeable. 40-64: Hormones continue to decline, fertility declines gradually for men; sharply for women after menopause. 65-74: Hormones continue to decline. 75+: Continued low levels of major hormones.
twin studies
studies that compare similarities of monozygotic twin pairs with dizygotic twin pairs on some behavior or trait of interest; results can give information on the extent of genetic contribution to that behavior or trait.
behavior genetics
study of the contributions genes make to individual behavior
Pruning
the ability to shut down neurons that are not needed in order to "fine-tune" the system and improve functioning of the remaining neurons. - most pruning takes place in infancy, but there is evidence of neuron loss in old age
Neurogenesis
the growth of new neurons - researchers have found that neurogenesis takes place throughout the adult years, primarily in the dentate gyrus, a small area of the hippocampus, which is crucial for forming memories
Race and ethnicity in health issues: Non-Hispanic blacks
- Adults classified as non-Hispanic blacks in the United States have shorter life expectancies than white adults, especially black males. They have the highest rates of death from heart disease, cancer, stroke, diabetes, HIV, and homicide than any other racial or ethnic group in the United States
The climacteric in women
- During middle adulthood, women's menstrual periods become irregular, then further apart, and then stop altogether - menopause (main cause is ovarian failure, leading to a drop in estrogen and complex changes in progesterone, both important hormones in women's reproductive health.)
Gender differences in health issues
- Men have shorter life expectancies than women and higher rates of heart disease, hypertension, death by accident, and overall cancer rates. - Women live longer than men, but when they die, they do so from basically the same diseases that men do; they just develop them later in life. Women have more chronic health conditions than men, including arthritis, asthma, migraine headaches, thyroid disease, gallbladder problems, and urinary and bladder problems, among others
Race and ethnicity in health issues: non-Hispanic white adults
- Non-Hispanic white adults have the longest overall life expectancy of any group in the United States. They have the highest rates of anxiety disorders, mood disorders, and substance abuse disorders, but are more likely to receive treatment
Alzheimer's disease
- a progressive, irreversible deterioration of key areas of the brain involved in various cognitive functions, short term memory is a common symptom - 5th leading cause for death for people over the age of 65
oxidative damage (theories of primary aging)
- based on random damage that takes place at the cellular level - involves the release of free radicals, molecules, or atoms that possess an unpaired electron and are by-products of normal body metabolism as well as a response to diet, sunlight, X-rays, and air pollution
Changes in cardiovascular system
- heart of a young person and old person functions the same unless there is a disease present - When the cardiovascular system is challenged (like during exercising) Then the older heart is slow to respond to the challenge and cannot increase its function as well as a younger heart - the walls of the arteries become thicker and less supple, so they do not adjust to changes in blood flow as well as younger arteries - This loss of elasticity can cause hypertension, or high blood pressure, which is more prevalent in older people than in younger ones
SES differences in health issues
- the health of people in lower SES groups in the United States is notably worse than that of people in higher SES groups - people in lower SES groups use health services less and have less adequate health-related behaviors than those in higher SES groups
The climacteric in men
- the quantity of viable sperm produced begins to decline in a man's 40s (decline is not rapid, men in their 80's can still have children) - The testes shrink gradually, and after about age 60, the volume of seminal fluid begins to decline. - Declining hormone levels in men are also associated with decreases in muscle mass, bone density, sexual desire, and cognitive functions and with increases in body fat and depressive symptoms
What are normative age-graded influences?
Changes associated with age
Phases of menopause
-Menopause is defined as occurring 12 months after a woman's final menstrual period. - Premenopause is the time when a woman is having regular periods, but hormone levels have begun to change. - Perimenopause is the time a woman begins having irregular periods but has had a period in the last 12 months. - Postmenopause is the time after a woman has not had a period for 12 months, and it extends until the end of her life
Changes in vision, hearing, and taste and smell
18-24: Vision is at peak acuity, hearing may start to decline but is not likely 25-39: Beginning of vision and hearing losses, declines in taste and smell, but not generally noticeable 40-64: Near vision loss in 40s; dark adaptation becomes apparent in 60s; cataracts begin in 40s. Slight losses in taste and smell. Hearing loss is more noticeable. 65-74: Vision loss continues. Cataracts common. Loss of taste and smell becomes noticeable, especially sweet and salty tastes. 75+: Visual and hearing losses continue.
When do most adults pass their physical peak?

Caloric restriction (theories of primary aging)
One of the most promising explanations of why we age is that aging is connected with our diets—not so much what we eat, but how many calories we metabolize per day.

Plasticity

Genetic limits (theories of primary aging)
The theory of genetic limits centers on the observation that every species has a characteristic maximum life span. Something between 110 and 120 years appears to be the effective maximum life span for humans
Upswing and downturn in weight
The upswing in weight that takes place during young adulthood and middle age can be attributed to our tendency to become more and more sedentary during that time without changing our eating habits to compensate. The downturn in total body weight that takes place in later adulthood is due to loss of bone density and muscle tissue

Type A behavior pattern: state of being achievement-striving, competitive, and involved in one's job to excess People with a type A personality are at a greater risk for coronary heart disease than those with type B
Why do wrinkles occur?
Wrinkles are a natural part of the aging process. As people get older, their skin gets thinner, drier, and less elastic, and less able to protect itself from damage.
