A population-based study of health-promoting behaviors and their predictors in Iranian women of reproductive age.

Health-promoting behaviors have been recognized as major factors for maintenance and improvement of health. The objective of this study was to determine the status of health-promoting behaviors and their predicting factors in Iranian women of reproductive age. This was a population-based cross-sectional study in which 1359 Iranian women of reproductive age were selected by proportional random multistage cluster sampling in Tehran. Questionnaires including sociodemographic characteristics, Health-Promoting Lifestyle Profile-II (HPLP-II) and Personal Resource Questionnaire 85-Part 2 (PRQ85-Part 2) were completed by interview. The association between the dependent variables (HPLP-II and subscales) and the independent variables (social support and sociodemographic characteristics) was analyzed using the multivariable linear regression model. Among the six dimensions of health-promoting behaviors, women scored highest in interpersonal relations (3.08 ± 0.51) and lowest in physical activity (2.04 ± 0.64). The Pearson test indicated perceived social support to be significantly correlated with HPLP-II (r = 0.53; p < 0.001) and all its subscales (r = 0.12-0.60; p < 0.001). Multivariable regression analysis indicated social support to be a predictor of HPLP-II and all its subscales, except for physical activity. Social support and sociodemographic characteristics accounted for 29.8% of the variance in the HPLP-II score and 6.9-39.3 in the six subscales. The findings of the present study confirm the importance of social support and modifiable variables (sociodemographic) in the occurrence of health-promoting behaviors in women and accredit the theoretical relationships among the concepts of the health-promotion model.
