The effect of a community-based health promotion intervention to improve utilization of healthy lifestyle centers in Sri Lanka

Abstract

Background: Healthy lifestyle centers (HLCs) report underutilization by the target population. There is a dearth of evidence on improving HLC utilization through the Health Promotion (HP) approach. This study aims to evaluate of the effectiveness of a HP intervention in improving the utilization of HLCs.Methods: A quasi-experimental study was conducted in six grama niladari divisions from the catchment area of two selected HLCs, one each in Gampaha (intervention) and Kalutara (comparison) districts. Community support groups (CSGs) were developed and empowered as the intervention. Contributory factors for the underutilization were addressed with the CSG.The pre and post intervention assessments were done in a random sample of 498 (aged 35-65 years) from each group. Primary outcome was improvement in the attendance of the HLC and secondary outcomes were changes in contributory factors. Data collected using an interviewer-administered questionnaire and secondary data from the HLCs were used. Results: Utilization of the HLC improved significantly among the sample from the intervention group (Post 35.3% [95% CI: 30.9 - 39.8]; Pre 5.85% [95% CI: 3.74 - 7.95], P < 0.001). The comparison group showed no significant change (Post 3.49% [95% CI: 1.80 -5.17] - Pre 3.25% [95% CI: 1.62 - 4.87], p = 1.00). There was a significant improvement in mean HLC attendance in the intervention group (Mean difference= 91.83, P < 0.05) compared to the comparison group (Mean difference = 2.66, P > 0.05). Conclusions: The utilization of the HLCs can be improved by a HP intervention through developing and empowering CSGs.
