Stability and change in health-related behaviors of midlife Swedish women.

We investigated the dimensions and stability in health-related behaviors (HRBs) among midlife Swedish women, and the factors that predicted change in those behaviors. At age 43, 569 women from a representative longitudinal sample completed questionnaires about lifestyle (diet, exercise, smoking, alcohol) and participated in medical screening. Four years later we mailed a follow-up questionnaire. HRBs clustered in two dimensions: healthy eating and addictions. There was a high degree of stability in HRBs; all women slightly increased their HRBs over time. After controlling for previous HRBs, we found that education, marital status, and having children at home were significant predictors of HRBs 4 years later.
