Abstract
The rising prevalence of hypertension in developing countries has been attributed to changing lifestyle and exposure to modifiable risks. Interventions that particularly target high risk sub-population groups such as informal sector workers are underexplored. This study was undertaken to assess the effectiveness of on-site behavioural modification intervention on modifiable risk factors for hypertension among market traders in a metropolitan city. A non-randomized intervention study with control arm was conducted among market traders. A lifestyle/behavioural modification programme consisting of on-site health education on prevention, early detection and control of hypertension through increased physical activity, and dietary adjustment was adapted and implemented. Pre-tested structured questionnaire was used to collect data from 379 traders that were selected through systematic random sampling technique. Descriptive and inferential statistics were performed at 95% confidence interval. There was statistically significant difference in proportion of participants with adequate physical activity in intervention group compared to control group (p < 0.001). Among intervention group participants, there was a statistically significant increase in the proportion with adequate consumption of fruits and vegetables (p<0.001); significant decreases in the proportion with excessive alcohol consumption/binge drinking (p<0.001), and proportion with ≥2 risky behaviours for hypertension (p<0.001). Age and sex were predictors of ≥2 risky behaviours for hypertension. Lifestyle modification programme was effective in reducing risky behaviours that predispose traders to hypertension, and it should be promoted within large markets.
