Lifestyle factors of a five-year community-intervention program: the Hartslag Limburg intervention.

BACKGROUND: 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

Effect of 5-year community intervention Hartslag Limburg on cardiovascular risk factors.

BACKGROUND: A widely advocated strategy in public health is community-based health promotion. The aim of this study was to investigate the net effect of a cardiovascular disease prevention program (Hartslag Limburg) on cardiovascular risk factors after 5 years of intervention. DESIGN: Cohort study comparing 5-year mean change in risk factors between the intervention and reference area. The statistical analyses for the study were performed in 2005. SETTING/PARTICIPANTS: In 1998, 3000 subjects (aged 25 to 70) from the intervention area and 895 subjects from a reference area participated in the baseline measurement. Of these, 2414 intervention subjects and 758 reference subjects completed the follow-up measurement in 2003. INTERVENTION: Hartslag Limburg is an integrative community-based cardiovascular disease prevention program promoting a healthy lifestyle. MAIN OUTCOME MEASURES: Body mass index (BMI), waist circumference, blood pressure, serum glucose (nonfasting), and serum total and high-density lipoprotein (HDL) cholesterol. RESULTS: During the 5-year follow-up, risk factors changed unfavorably in the reference group, whereas changes were less pronounced or absent in the intervention group. The adjusted difference in mean change in risk factors between intervention and reference group was significant (p<0.05) for BMI: -0.36 kg/m(2) in men and -0.25 kg/m(2) in women; waist circumference -2.9 cm in men and -2.1 cm in women; systolic blood pressure: -7.8 mmHg in men and -5.5 mmHg in women; total cholesterol 0.11 mmol/L in women and finally serum glucose -0.23 mmol/L in women. CONCLUSIONS: Hartslag Limburg succeeded in reducing-and in some cases, preventing-age- and time-related increase in BMI, waist circumference, blood pressure, and, in women, nonfasting glucose concentration.
