Effectiveness of community interventions on blood pressure control among hypertensives-a meta-analysis

Objective To evaluate the influence of community intervention on blood pressure control among hypertension patients with meta-analysis.Methods Related articles published between 2004 and 2014 were searched through China National Knowledge Infrastructure(CNKI), VIP Chinese Science and Technology Periodical Database(VIP), Wanfang Database(Wanfang), Chinese Biomedical Literature Database(CBM), PubMed, and Web of Science Databases, and selected according to inclusion and exclusion criteria.The systolic and diastolic blood pressure for intervention group and the control group after community-based intervention were chosen as indicators.Stata 12.0 software was employed in the meta-analysis.Results A total of 18 articles met inclusion criteria.Meta-analysis showed that there were statistically significant differences between the community intervention group and the control group in systolic blood pressure(standardized mean differenceSMD=-0.65, 95% confidence interval(95% CI):-0.89, -0.41);P<0.001), and diastolic blood pressure(SMD=-0.51, 95% CI:-0.71, -0.31;P<0.001).Sensitivity analysis revealed that the results of this meta-analysis were stable.Conclusion The meta-analysis shows that systolic and diastolic blood pressure decrease after community interventions among hypertension patients but large-scale randomized controlled trials with higher-quality are needed to confirm the effectiveness of community intervention.
