Community-Based Occupational Health Promotion for Reducing Blood Pressure: A Randomized Control Trial of Agricultural Health Program

Background: Farmers need the right strategy to control blood pressure through Community-Based Occupational Health Promotion (COHP) Program interventions for reducing blood pressure.This study aims to analyse the effectiveness of COHP interventions to maintain blood pressure of farmers.Materials and Methods: This study used a randomized control trial design.COHP interventions were performed in intervention (68 participants) and control (67 participants).The study was conducted for 24 weeks with intervention at 0-4 weeks and continued with follow-up at 5-24 weeks for participants in four Public Health Centres (PHC) areas in Indonesia.Data were collected using a stethoscope and aneroid sphygmomanometer to measure blood pressure.Data were analysed using Fisher's exact test, to analyse the differences in systolic (SBP) and diastolic (DBP) blood pressure in both groups.Results: In after 24 weeks of CHOP, there were significant differences SBP between intervention and control groups (126.81 14.52 Vs. 146.65 16.38; p< 0.001).Meanwhile, there were significant differences DBP between intervention and control groups (83.03 8.31 Vs. 86.91 7.73; p= 0.003).Furthermore, the COHP was effective for reducing SBP and DBP (p< 0.001) among farmers.Conclusions: This study indicates that COHP can be effective for reducing SBP and DBP among farmers in agricultural areas.
