  1. 1General estimating equation models adjusted for sex, age, education, smoking, adherence to an energy-restricted Mediterranean diet, and baseline body mass index (BMI) were used to analyze the effect of the intervention on secular trends of leisure-time physical activity in comparison with the control group. Leisure-time PA data were log-transformed for analysis. Absolute values are presented in mean and standard error (SE) and relative change in exponential beta coefficient (95% confidence interval)
