Introduction; ; Uganda is experiencing a significant increase in the prevalence of non-communicable diseases including hypertension and obesity. Frequent alcohol use is also highly prevalent in Uganda and is a key risk factor for both hypertension and obesity. This study explores the association of alcohol with hypertension and obesity across different age groups.; ; Methods; ; The data were extracted from the 2014 National Non-communicable Diseases Risk Factor Survey (N=3,987) conducted among adults aged 18 to 69 years. Hypertension was measured by blood pressure ≥140mmHG. Obesity was measured by body mass index >30 kg/m2. Frequent alcohol consumption was measured as alcohol use 3 or more times a week. Multivariable log binomial regression analysis was carried out for each of the two outcome variables against age group and controlled for frequency of alcohol consumption and few other independent factors. Non-parametric tests were used to compare trends of prevalence ratios across age groups.; ; Results; ; The results show increasing trend in the prevalence of hypertension and frequent alcohol consumption but a declining trend for obesity along different age groups (p<0.01). Frequency of alcohol consumption did not significantly modify the age group-hypertension and age group-obesity relationships although the effect was significant with ungrouped age. There was significance in difference of fitted lines for hypertension prevalence ratios between frequent drinkers and mild drinkers and between abstainers and frequent drinkers. Alcohol consumption did not have any significant effect on obesity-age group relationship.; ; Conclusion; ; The results call for more research to understand the effect of alcohol on the hypertension-age and obesity-age relationship. Why prevalence ratios for hypertension decline among those who take alcohol most frequently is another issue that needs further research.
