obesity psych results

stigma --> avoid medical checkups, eat more, exercise less

best obesity treatment

sustained counseling and encouragement are best

best age of conception biologically

peak: 25 women: before 30 men: before 40

adulthood: height

starts decreasing by middle age: 50s and beyond -back muscles, CT, and bones lose density --> vertebrae in the spine shrink -people lose about 1 inch of height by age 65

menopause definition; age?

time in middle age (42-58; avg age: 51) in which periods stop because hormone levels decrease

women who wait until 30s are more emotionally adjusted

medical assistance for giving birth with HIV

women: medical help can almost always help the fetus -men: sperm can be collected and washed in the lab to rid them of the virus --> IVF

obesity in the US

world leader in obesity and diabetes -obesity in the US hasn't changed since 2000

presbycusis

a loss of hearing associated with senescence; usually not apparent until age 60

how many try ART?

about half of infertile US couples try this --> not always successful, expensive, long, no guarantees or privacy

decreases over adulthood -marijuana is the slowest to decline -8-10% of 25-35 year olds still use marijuana

oxygen and age

organ reserve capacity decreases; vital capacity is reduced; oxygen dispersal into the blood from the lungs drops 4% per decade --> breathing become quicker and more shallow

disability: what? results?

-difficulty in performing ADLs bc of some physical, mental, or emotional condition -hurts a society more than mortality or morbidity if people with disabilities are less able to contribute to the general welfare

HRT results for women

-diminishes menopause symptoms and decreases osteoporosis -taking estrogen for 10+ years causes increased risk of heart attack, stroke, breast cancer

-daily about 100 mill sperm reach maturity after 75 day dev process --> anything that impairs body functioning over this period can reduce sperm number, shape, and motility

adulthood: vision

-peripheral vision narrows faster than central vision -color vision shifts from vivid to dull faster than black and white -nearsightedness increases and begins at age 20 -farsightedness doesn't appear until 40-45 -younger adults are usually either nearsighted or farsighted, but by the middle of this stage, you are usually both -takes longer for eyes to adjust to darkness or glare

-presbycusis usually around age 60

heavy alcohol consumption

0can be one of the #1 things that becomes addictive and leads to violence -destroys brain cells, contributes to osteoporosis, decreases fertility, accompanies many suicides/homicides/accidents; more than 60 diseases including liver damage and breast/stomach/throat cancer

steps to break habits

1. denial 2. awareness 3. planning 4. implementation 5. maintenance

adulthood: severe brain loss causes

1. drug abuse: consistent alcohol use/abuse leads to "wet brain" --> Wernike-Korsakoff syndrome (wet brain) which is low Vit B 2. viruses e.g. HIV can destroy neurons 3. poor circulation impairs blood flow; can be caused by cigarette smoking and HBP 4. genes: dominant gene for Alzheimer's (1/1000 people)

ways of coping with stress

1. problem-focused coping 2. emotion-focused coping -adults need both depending on the situation -Attitude sometimes determines whether or not an event becomes a stressor

conception for women age 40

1/2 are infertile, the other half risk Down syndrome and neurodevelopmental issues

adulthood ages

25-65

adulthood: prescribed drugs

abuse of prescription drugs increases -they are prescribed more pain medications because they have more pain management issues --> can abuse them more easily -adults are slower to recognize that pain and medications can be addictive -you are going to like your doctor more if they give you more pain medication --> doctors are too quick to prescribe pain medications --> should explain addictive qualities

adulthood: health worldwide

US has lower life expectancy and higher morbidity rate than several poorer nations -immigrants are healthier but poorer than native-born

adulthood: weight

adults gain about 1-2 pounds per year -excessive weight increases the risk of every chronic disease

age 10 but perfect hearing is always impossible

stressor definition

any situation, event, experience, or other stimulus that causes a person to feel stressed

infertility: female issues

anything that impairs physical functioning: advanced age, extreme dieting, obesity, pelvic inflammatory disease that blocks fallopian tubes

adulthood: brain size and results

brain size literally decreases --> memory tasks and multitasking are harder and processing time is longer

hormone replacement therapy: why?

compensate for reduction in menopause or after ovary removal -diminishes menopause symptoms and decreases osteoporosis

adulthood: metabolism

decreases by 1/3 between age 20 and 60

adulthood: skin

drier, rougher, less regular in color -collagen decreases with 1% per year beginning at age 20 --> by age 30, skin is less flexible and there are more wrinkles --> by age 60, all faces are wrinkled -fat cells decrease wrinkles

education teaches healthy habits -education leads to higher income --> better housing and medical care -education may be a marker for intelligence which is a protective factor

HRT in men

effectiveness is questionable

IVF procedure

egg cells are surgically removed from woman --> fertilized by sperm in lab --> replaced in woman

what does senescence affect?

every part of the body -organ reserve capacity decreases; vital capacity is reduced; oxygen dispersal into the blood from the lungs drops; breathing becomes quicker and more shallow -increased BP and LDLs

adulthood: how to slow effects of aging

exercise --> physical fitness is very much correlated with brain functioning

adulthood: how they feel

feel 5-10 years younger than they are --> strong, capable, healthy, and "in their prime"

adulthood: neurons

fire more slowly -messages sent from the axon of one neuron are not picked up as quickly by the dendrites of another --> slowed reaction time

what is HRT?

giving a woman estrogen or progesterone

adulthood: happiness

increases with age: adults are more happy and less depressed than emerging adults

alcohol worldwide

low-income nations have more abstainers and more abusers -high-income nations have more moderation

results of stress

lowers immunity, increases BP, speeds up HR, reduces sleep, produces other reactions that can lead to serious illness -can increase drug use, overeating, and underexercising

diseases of affluence

lung and breast cancer --> now more common among the poor

andropause

male menopause -reduction of sexual desire, erections, and muscle mass -implies a drop in hormone or reproductive ability, but it actually is a decreased sex and increased stress/performance anxiety that causes decreased testosterone
