The present paper examines reported frequencies of 21 health practices, beliefs that these health practices can prevent six different illnesses, and beliefs about those illnesses in a community sample of 396 people: 173 young (20 to 39 years), 111 middle-aged (40 to 59 years), and 112 elderly adults (60 to 89 years). Elderly respondents report higher frequencies of health-promoting actions (e.g., regular medical check-ups, avoidance of salt, regular sleep, and eating a balanced diet) than younger respondents. Health practices aimed at reinterpreting stress and controlling emotions (e.g., avoiding emotional stress, staying mentally alert and active) also increased with age. Belief that these 21 practices prevent specific illnesses was consistent across the three age groups. Beliefs about the six illnesses were consistent across age with three exceptions: Elderly people considered themselves more vulnerable to disease, saw it as more serious for them, and were less likely to use chronic mild symptoms, like weakness and aches, as illness warnings.
