Research article: Lifestyle Factors of a Five-Year Community-Intervention Program: The Hartslag Limburg Intervention

Community-based health promotion is a widely advocated strategy in public health to favorably alter lifestyle. The aim of this study was to investigate the net effect of a cardiovascular disease-prevention program (Hartslag Limburg) on lifestyle factors after 5 years of intervention (1998-2003). Methods In a cohort study, 5-year mean changes in lifestyle factors (energy intake; fat intake; time spent on leisure-time physical activity; walking, bicycling, and sports; and smoking behavior) between subjects from the intervention area (n=2356) and the control area (n=758) were compared for men and women and for those with a low (less than intermediate secondary education) and a moderate (intermediate vocational or higher secondary education) or high (higher vocational education or university) educational level. Adjustments were made for age and the mean of the individual pre- and post-intervention measurement of the variable under study. When stratifying for gender, adjustments were made for educational level, and vice versa. Results In general, lifestyle factors changed unfavorably in the control group, whereas changes were less pronounced or absent in the intervention group. The adjusted difference in mean change in lifestyle factors between the intervention group and the control group was significant (p
