Background The purpose of this study was to analyse both cross-sectional associations and how longitudinal changes in lifestyle factors from one state in 1980-1981 to another in 1988-1989 influence self-reported health status. Another aim was to estimate the hazard ratios for all-cause mortality for the changes in lifestyle factors and self-reported hypertension during the same period of time. Method The cross-sectional and the longitudinal analyses are based on the same simple random sample of 3843 adults, aged 25-74, interviewed in 1980-1981 and 1988-1989 and is part of the Swedish Annual Level-of-Living Survey. About 85% of the respondents in the first interview participated in a second interview in 1988-1989. Cross-sectional odds ratios, based on a marginal model, were estimated using the generalized estimating equations. The transitional models were analysed using unconditional logistic regression. A proportional hazard model was applied to investigate the influence of lifestyle transitions on mortality. Results Physical inactivity, being a current or former smoker and obesity (women only) were strong risk factors for poor health either as main effects and/or combined (interactions). There was a strong interaction between physical activity and smoking, and for women, also between body mass index (BMI) and physical activity. (...)
