Abstract:
Background: Excessive alcohol consumption is a preventable cause of mortality and morbidity. Objectives: To determine the prevalence and patterns of alcohol consumption among different sociodemographic groups in Sri Lanka. Design, setting and methods: We recruited a nationally representative sample of 4532 individuals over 18 years by a multi-stage cluster sampling technique in 7 out of 9 provinces in Sri Lanka. Data collected using an interviewer -administrated-questionnaire. Results: Among 4532 adults, 39.6% were males. The prevalence of current drinking and past drinking among males and females were 46.9% vs. 1%, (p<=3 units of alcohol per week, while 2.3%, 2.5%, 2.2%, 1%, and 4.6% drank 4-7, 8-14, 15- 21, 22-35, >36 units per week respectively. Highest drinking (23.2%) was in 30- 39 age group and lowest (10.5%) in ?70 age group. Prevalence was highest in the plantation sector (66%) followed by the urban (54.7%) and the rural (43.5%) sectors (p> 0.001) More males who only had school education drank (47.5%) compared to those with higher education (34.2%), p> 0.001. Prevalence was highest (58.3%) in the highest income group and lowest (43.0%) in the lowest. Drinking was low among those with known hypertension (35.8% vs. 48.6%, p=0.003), known diabetes (44.4% vs. 47.3, p=0.602) and known ischaemic heart disease (31.7 vs. 47.6, p=0.08) compared to those without these conditions. Conclusions: Alcohol consumption was predominantly seen among males and associated with the area of residence, level of education and income. Prevalence was less among those with hypertension.
