CHWs are Effective for Diabetes Prevention and Management in India
A Community-Based Participatory Diabetes Prevention and Management Intervention in Rural India Using Community Health Workers
This study tested the effectiveness of a 6-month community-based diabetes prevention and management program in rural Gujarat, India. A community-based participatory research method was used to plan and tailor the intervention by engaging trained community health workers as change agents to provide lifestyle education, serve as community advocates, and collect data from 1638 rural Indians (81.9% response rate). Ten culturally and linguistically appropriate health education messages were provided in face-to-face individual and group sessions (demonstrations of model meals and cooking techniques).
Mean age was 41.9 ± 15.9 years. Overall point prevalence of diabetes, prediabetes, obesity, and hypertension were 7.2%, 19.3%, 16.7%, and 28%, respectively, with significant differences between the low socioeconomic status (SES) participants (agricultural workers) and the high SES participants (business community) due to differing diet and activity levels. The intervention significantly reduced blood glucose levels by 5.7 and 14.9 mg/dL for individuals with prediabetes and diabetes, respectively, and systolic and diastolic blood pressure by 8 mm Hg and 4 mm Hg, respectively, in the overall population. Knowledge of diabetes and cardiovascular disease improved by 50% in the high SES group and doubled in the low SES group; general and abdominal obesity also decreased by ≤ 1%.
