Health, Illness, and Disease
• Adolescents’ health– Many factors and lifestyle linked to both poor
health habits and early death in the adult years begin during adolescence

Health, Illness, and Disease
• Emerging and young adults’ health– 2x higher mortality rate of adolescents– Fewer chronic health problems– Fewer colds, respiratory problems– Little thought about lifestyle’s links to health
• Poor lifestyles associated with poor health– Impacts on life satisfaction
• Negative effects of abusing the body

Health, Illness, and Disease
• Health and aging– Alzheimer’s disease linked to aging– 17% of US adults aged 65 to 74 have a disability– 50% of US adults are free of disability until age 85
• Chronic disorders– Slow onset, long duration, higher rates for males
• Arthritis, heart conditions, diabetes, asthma• Types vary by gender in middle age

Health, Illness, and Disease
• Health and aging– Osteoporosis
• Extensive bone tissue loss; affects walking• 80% of US cases: females, broken bones
– White, thin, small-framed women• Affects 66% of women over age 60 • Healthy diet, exercise, medications reduce risks

Health, Illness, and Disease
• Health and aging– Dementia
• Neurological disorder; mental functioning loss• 20% of all over age 80 have dementia
– Alzheimer disease (form of dementia)• Progressive, irreversible, gradual loss to death• 2008: about 5.2 million Americans affected• Onset varies: age, genes, lifestyle

Health, Illness, and Disease
• Health and aging– Early detection of Alzheimer disease

Health, Illness, and Disease
• Health treatment for older adults– Alternative home, community-based care
• Nursing homes used less; need increases as person ages
– Nursing homes: Quality varies enormously– Problems: failed inspections, minimal standards,
over 1/3 have serious deficits, patient rights issues– Best care promotes ‘patient self-control’

Health, Illness, and Disease
• Health treatment for older adults– Rodin and Langer study:
• Self-control in care linked to longevity, activity level, alertness, happiness, needs satisfaction

Nutrition and Eating Habits
• Infancy – Nutrition important for development and growth– Breastfeeding versus bottle feeding:
• Controversial; breast feeding appears better– Rate has increased in US since 1970– Benefits: fewer gastro/respiratory infections; reduces
risks of asthma, diabetes, SIDS– Lowers risk of ear/skin infections– Benefits mother: lowers risk of diseases

• Being overweight increases risk of middle age death — 40% higher
• Worldwide: rates for women increasing faster• Environment has dramatic effect — greater access to
food/higher fat content

29
Nutrition and Eating Habits
• Adult development– Exercising and diet
• Most effective weight loss/control is exercise– 30 minutes a day, healthy meal planning– Daily weighing; keep a food diary

Nutrition and Eating Habits
• Adult development– Controversy over vitamins and aging
• Recent research: – Antioxidants may slow aging – No evidence of extending the life span– Others: vitamins reduce risk of frail/ill life
• Possible link: vitamins to cognitive performance

31
Exercise
• Childhood and adolescence– Childhood
• All children need daily exercise• Electronics, computers, TV deter activity• Recent study: preschools vary in physical activity,
methods of teaching influence activities• Aerobic exercise linked to increased cognitive activity
(planning)

32
Exercise
• Childhood and adolescence– Adolescence
• Activity usually decreases in adolescence• Recommended: exercise 1 hour per day • Boys more active than girls; body image issues• Childhood habits continue in adolescence• Rates vary by gender: white boys exercise most, African
American girls exercise least• Develop ways to encourage exercise

Exercise
• Adulthood– Moderate/intense exercise may have physical and
psychological gains• Prevention of heart disease, live longer • Aerobic exercise: sustained activity that stimulates
heart/lung functioning • Burn 2,000 calories a week to cut heart attack risk by
two-thirds• Exercise aids mental and physical health
