03 Health Promotion in Adulthood

Health promotion across adulthood

Adult health promotion aims to maintain function, prevent disease and injury, and support physical, mental, and social well-being. Health needs and priorities vary with age, health and family history, identity, environment, and personal priorities. Young adulthood and middle adulthood are useful planning categories, not fixed timetables for development.

Priorities in young and middle adulthood

Young adulthood often involves increasing independence and decisions about education, work, relationships, sexuality, and family life. Health care can help adults build lasting habits, manage stress, protect sexual health, and make informed choices about contraception and reproductive goals. Injury prevention, including safer driving, and screening for mental health concerns and substance-use risks are also important.

Middle adulthood is a key period for identifying and managing risks that accumulate over time, especially cardiovascular disease, type 2 diabetes, and some cancers. Changes in strength, metabolism, vision, or reproductive health may occur, but physical changes differ among individuals. Perimenopause and menopause, for example, can bring symptoms and changes in bone and cardiovascular health; ask about concerns rather than assuming a change is inevitable or the same for everyone.

In both periods, relationships, caregiving, work, finances, and major life transitions can affect health. Social connection and mental well-being are part of health promotion.

Habits, risks, and supportive education

Preventable risks include tobacco and nicotine use, physical inactivity, poor nutrition, excessive alcohol use, inadequate sleep, and untreated high blood pressure or other chronic conditions. Risk is also shaped by family history, access to care, stress, housing, work conditions, and other social and environmental factors. Prevention should combine individual support with attention to barriers to care.

Practical health education can support achievable steps:

• Physical activity: Work toward at least 150 minutes of moderate-intensity activity per week or 75 minutes of vigorous activity, plus muscle-strengthening activity on at least 2 days. Starting with short sessions and increasing gradually is useful; some activity is better than none.

• Nutrition: Emphasize a varied pattern of vegetables, fruits, whole grains, protein foods, and other nutrient-dense choices. Limit highly processed foods, added sugars, and excess sodium. Adapt advice to culture, preferences, health needs, and budget.

• Sleep and substance use: Encourage adequate sleep and avoiding tobacco and nicotine. Discuss alcohol or other substance use without judgment. When someone wants to change their use, offer support and follow-up rather than relying on warnings alone.

• Safety and sexual health: Discuss seat belts, injury prevention, consent, contraception, and sexually transmitted infection prevention in ways that fit the person's circumstances and goals.

A useful education approach is to agree on one specific, realistic next step, such as a 15-minute walk after work three days this week, and revisit how it went. Invite questions, use clear language, and ask the person to explain the plan in their own words to check understanding.

Preventive care and screening decisions

Preventive care includes screening, vaccination, counseling, and follow-up. Screening is intended for people without symptoms; diagnostic testing is used when symptoms or signs are present. A positive screening result usually requires further evaluation.

Screening decisions should account for age, anatomy, medical and family history, previous results, risk factors, preferences, and the potential benefits and harms of testing. Examples of U.S. recommendations include:

• Blood pressure: Screen adults aged 18 years or older. Elevated readings are generally confirmed outside the clinic before a diagnosis is made.

• Type 2 diabetes: Screen adults aged 35 to 70 years who have overweight or obesity. Consider effective prevention support when prediabetes is found.

• Colorectal cancer: Offer screening to average-risk adults aged 45 to 75 years. For adults aged 76 to 85 years, individualize the decision based on health, prior screening, and preferences.

• Depression: The USPSTF recommends screening adults, including pregnant and postpartum adults. A positive screen should be followed by assessment and appropriate care.

Other screenings, including those for breast or cervical cancer, sexually transmitted infections, HIV, hepatitis C, or lung cancer, depend on age, anatomy, history, and risk. Review eligibility and timing with a qualified health professional; not every adult needs every test. Keep recommended vaccinations current using the CDC adult schedule, which accounts for age, prior doses, health conditions, and other indications. Screening and vaccination choices should follow current guidance and reflect the person's individual risks, history, and preferences.
