Health

• Health, Illness, and Disease

• Nutrition and Eating Behavior

• Exercise

• Substance Use and Addiction

Slide 3


The Bio-Psycho-Social Health Model

• Asia and Greece: ancient physicians believed good habits essential to good health

• New model that health is best understood in terms of

– Biological Factors

– Psychological Factors

– Social Factors

Health, Illness, and Disease

Slide 4


Children's Health

• In last 50 years– Shift toward prevention and outpatient care– Vaccines prevent many diseases – Children’s motor, cognitive, and socio-emotional development makes health care needs unique– Caregivers play important role

• Poverty is a special concern– Approximately 11 million preschool children in U.S. malnourished

Slide 6


Adolescents' Health

• A Critical Juncture in Health– Many factors linked to both poor health habits and early death in the adult years begin during adolescence– Families, peers, schools influence health

• Health Services– Use private physician services at lower rate than other age groups; lowest use by older males


Slide 7


Young Adults' Health

• Most have few chronic health problems

• Know how to stay healthy but adopt unhealthy lifestyles

• Many college students unrealistic, overly optimistic about future health risks

• Hidden dangers in peaks of performance and health in early adulthood


Slide 8


Gender, Health, and the

Health-Care System • Women and men experience health and

health-care system differently – Males may use health care inadequately

– Special concerns for women’s health issues

• Medicine — male-dominated profession

• Gender bias affects medical research– Most research conducted with men


Slide 9


Chronic Disorders

• Characterized by slow onset, long duration• Gender differences

– Fatal chronic disorders affect men more– Nonfatal chronic disorders affect women more

• Socioeconomic differences– Poor older adults 3 times more likely than non-poor to be limited by chronic disorder


Slide 10


Increasing Disabilities with Age


Fig. 4.2

Slide 11


Osteoporosis

• Aging disorder involving extensive bone tissue loss– Related to calcium deficiencies

• Gender differences — 80% of cases women– Affects 2/3 of women over age 60– Common in white, thin, small-framed women

• Diet, exercise, weightlifting can help


Slide 12


Alzheimer's Disease

• Dementia — global term; Alzheimer is one form

• Progressive, irreversible brain disorder with gradual deterioration of memory, reasoning, language, and, eventually, physical function

– Rate increasing in U.S.; no cure

– Causes not fully identified; early and late onset

– Healthy lifestyle, medication can slow progression


Slide 13


Alzheimer's Disease

– Early detection: MCI and special brain scans

– Caring for patients is exhausting, some respite care available

• Parkinson disease– Another type of dementia, no cure

– Chronic and progressive, triggered by loss of dopamine production in brain

– Medication available, loses effect over time


Slide 14


The Robust Oldest-Old

• Persons 80 years and older

– Frail image fueled by media

• A substantial subgroup of oldest old are robust and active

– Less than 60% have a disability

– Health care and medical treatment can improve functioning, provide intervention


Slide 15


Health Treatment for Older Adults

• Probability of living in nursing home increases with age

• Quality varies enormously– 1/3 are seriously deficient; cause for national concern, fail inspections

• Home health care, elder-care centers, preventative medicine good alternatives


Slide 16


Percentage of U.S. Older Adults of Different Ages In Nursing Homes


Fig. 4.4

Slide 17


Health Treatment for Older Adults

• Important factors for residents

– Feelings of control and self-determination

– Alert, responsive, caring staff

– Effective coping skills

– Opportunities to make choices

– Positive staff, absent of stereotyping beliefs

– Active role in medical encounters


Slide 18


Perceived Control and Mortality


Fig. 4.5

Slide 19


Infancy

• Breastfeeding versus Bottle-Feeding• Benefits of breastfeeding:

Nutrition and Eating Behavior

– Denser bones in childhood

– Reduced risk of SIDS

– Advanced neurological, cognitive development

– Better vision

– Appropriate weight gain

– Lowered risk of childhood obesity

– Fewer allergies, lower risk of illnesses

Slide 20


Infancy

• When breastfeeding is avoided– Physical difficulties– Lifestyle conditions– HIV virus

• Poor, developing countries– Few or no alternatives– Unsanitary health risks– Death rates linked to bottle-feeding


Slide 21


U.S. Breastfeeding Trends

Fig. 4.6


Slide 22


Malnutrition in Infancy

• Marasmus — wasting away of body tissues in first year; severe protein-calorie deficiency

• Kwashiorkor — deficiency in protein; child’s abdomen and feet swollen with water

• Nutritional supplements linked to long-term effects on cognitive development– Lowest SES groups benefited most


Slide 23


Nutrition in Childhood

• Poor nutrition is special concern for many low-income children in U.S. – Children showed more aggression, hyperactive and excessive motor behaviors

• Positive influences on nutrition and health– WIC program linked to reduced risk of obesity

• Malnutrition threatens many in developing countries during childhood


Slide 24


Healthy and Unhealthy Eating

• Most children’s diets need improvement – Eating away from home, high fat foods

• Good diet can have long-term effects

– Basal metabolism rate (BMR) — minimal amount of energy a person uses in a resting state - suggest how much to eat

– Include low fat foods, milk, vegetables, eaten with family away from TV


Slide 25


Childhood Obesity

• Consequences of Obesity– Increases child’s risk of medical problems– Low self-esteem and depression common; has links to bullying

• Treatment of Obesity– Diet– Exercise– Behavior modification

• Problem among adolescents


Slide 26


Increase in Overweight U.S. Adolescents

Slide 27


Ethnicity and Overweight in U.S. Adolescents


Fig. 4.9

Slide 28


Eating disorders

• Anorexia Nervosa — relentless pursuit of thinness through starvation– Most are white females from well-educated, middle- and upper-income families– Competitive families, high achievement goals– Media and American culture fashion image

• Bulimia Nervosa — individual consistently follows a binge-purge eating pattern


Slide 29


Adult Development and Aging

• Obesity– Heredity and environmental influences – Health problems increasing

• Dieting– Restrained eating — individuals who chronically restrict food intake to control their weight– Concern for fad diets and obsession with thinness– Most effective programs include exercise– Harms and benefits of various diets


Slide 30


Questions About Aging and Nutrition

• Food Restriction and Longevity– Food-restricted animals live longer, healthier lives– Leaner men live longer, healthier lives– Increase in body mass linked to earlier death

• The Vitamin-and-Aging Controversy– Antioxidant supplements may slow aging process, improve health of older adults; still controversial– Vitamin supplements help cognitive performance


Slide 31


Childhood and Adolescence

• Concern: lack of exercise and obesity – Boys more physically active at all ages than girls– Effects of TV watching, computers, video games– Childhood habits continue in adolescence

• Getting children and adolescents to exercise – More physical activity programs at school– Plan community and school exercise activities– Encourage families to focus on physical activity

Exercise

Slide 32


Exercise in Adulthood

• Moderate and intense exercise may produce important physical and psychological gains

– Prevention of heart disease, live longer

– Aerobic exercise: sustained activity that stimulates heart and lung functioning (e.g. jogging, cycling)

– Exercising enough to burn more than 2,000 calories a week can cut risk of heart attack by two-thirds

Exercise

Slide 33


Ways to Get Yourself to Exercise More

• Reduce TV time• Chart your progress• Get rid of excuses

– Eliminate “I don’t have time” by making exercise a priority

• Imagine the alternative• Learn more about exercise

Exercise

Slide 34


Aging and Longevity

Exercise benefits:

– Related to preventing and treating disability

– Counteract side effects of standard medical care, improve quality-of-life and outcomes

– Linked to increased longevity

Exercise

– Minimize physiological changes in aging, health

– Optimize body composition

– Related to prevention of common chronic diseases

– Associated with improved treatment of diseases

Slide 35

Slide 36


Drugs, Health, and Addiction

• Long menu of psychoactive drugs used around the world

– Alcohol use: religion, gender, nationality

– Cultural acceptability of substance abuse is no measure of safety

– Alcohol and cigarettes pose serious health and development risks for adolescents and adults

– Secondhand smoke

Exercise

Slide 37


Addiction

• Pattern of behavior characterized by overwhelming involvement with using a drug and securing its supply

– Psychological dependence

– Physiological dependence

– Withdrawal symptoms

• Whether addictions are diseases is matter of controversy

Substance Use and Addiction

Slide 38


Addiction

Disease model

• Biologically-based

• Lifelong disease that involves loss of control over behavior

• Requires medical and/or spiritual treatment

• Promoted by medical profession and AA


Life-process model

• Habitual response and source of gratification and security

• Can only be understood in context of persons’ lives, social relationships, experiences, and environments

Slide 39


Trends in Drug Use By U.S. Eighth-, Tenth-, and Twelfth-Grade Students


Fig. 4.13

Slide 40


Alcohol and Cigarettes

• Drinking has declined among U.S. adolescents, but rates still high– 19 percent of eighth graders, 48 percent of high school seniors drank in past 30 days– Binge drinking, mostly males

• Smoking has declined heavily– Prices, anti-tobacco ads, social disapproval– Can cause permanent genetic lung changes

• Roles of parents and peers


Slide 41


Fatal Lung Cancer andYears Since Quitting Smoking


Fig. 4.15

Slide 42


Substance Abuse in Adulthood

• Smoking and lung cancer risk decreasing; cigarette and cigar smoking still a concern

• Alcohol use remains accepted part of U.S. culture– Half of all college students drink heavily– Binge drinkers and reported problems– College students drink more than youths ending education after high school


Slide 43


Substance Abuse in Adulthood

• Patterns of use

– Persons not attending college smoke more

– Singles use marijuana more than marrieds

– Singles and divorced persons drink more

– Engagement or marriage reduces alcohol use

– Drug use lower among regular church attendees
