Abstract

Objectives: This study aimed to summarise the effect of community-based intervention programmes on the prevention of cardiovascular disease (CVD) by reducing cardiometabolic risk factors. Study design: This was a systematic review and meta-analysis. Methods: A systematic search in the PubMed database and screening of reference lists aimed to identify community-based CVD prevention programmes from inception up to April 2020. The mean differences and standard deviations for CVD risk factors, including blood pressure, lipid profile, blood glucose and body weight indices, were extracted and pooled using a random effects model. Results: Screening of 11,889 titles/abstracts and full texts resulted in 48 studies being included in this review. The meta-analysis showed that community-based programmes have led to considerable decreases in systolic blood pressure (weighted mean difference [WMD] = −2.90 mm Hg, 95% confidence interval [95% CI]: −3.63, −2.16), diastolic blood pressure (WMD = −2.21 mm Hg, 95% CI: −3.12, −1.29), serum levels of low-density lipoprotein cholesterol (LDL-C; WMD = −8.88 mg/dl, 95% CI: −12.84, −4.92), triglycerides (WMD = −8.40 mg/dl, 95% CI: −12.10, −4.70), total cholesterol (WMD = −2.96 mg/dl, 95% CI: −3.10, −2.81) and fasting blood glucose (WMD = −2.06 mg/dl, 95% CI: −3.02, −1.10). A moderate decrease in body weight was also found with community-based CVD prevention programmes. However, community-based CVD prevention programmes were not associated with any significant changes in serum levels of high-density lipoprotein. Conclusions: The present study indicates that community-based strategies have successfully led to an improvement in CVD risk factors, particularly by reducing blood pressure, serum levels of LDL-C and triglycerides, obesity indices and blood glucose. The impact of these programmes on CVD is modified by the type of intervention and by different cultural and physical environments. © 2021 The Royal Society for Public Health
