•We examined the effects of a lifestyle intervention on sedentary behaviors.•At short and long term, no relevant between-group differences were seen.•It is currently not advised to implement this type of lifestyle programs.
ObjectiveThis study set out to assess the short- and long-term effects of a primary care-based lifestyle intervention on different domains of leisure-time sedentary behaviors in Dutch adults at risk of type 2 diabetes and cardiovascular diseases.MethodsBetween 2007 and 2009, adults (n = 622) at risk were randomly assigned to a counseling intervention aimed at adopting healthy lifestyle behaviors, or a control group that only received health brochures. Follow-up measures were done after 6, 12 and 24 months. Linear regression analysis was used to examine between-group differences in self-report minutes per day sedentary behaviors, adjusted for baseline values. Stratified analyses were performed for sex and educational attainment.ResultsSeventy-nine percent (n = 490) of participants completed the last follow-up. Mean baseline sedentary behaviors were 254.6 min per day (SD = 136.2). Intention-to-treat analyses showed no significant differences in overall or domain-specific sedentary behaviors between the two groups at follow-up. Stratified analyses for educational attainment revealed a small and temporary between-group difference in favor of the intervention group, in those who finished secondary school.ConclusionsA primary care-based general lifestyle intervention was not more effective in reducing leisure-time sedentary behaviors than providing brochures in adults at risk for chronic diseases.
