The Use of Alcohol and Knowledge of Cardiovascular Diseases among Ellisras Rural Children Aged 14-22 Years: Ellisras Longitudinal Study.

The harm alcohol abuse does to physical and mental health is well established. The perception of cardiovascular disease risk factors and alcohol use requires attention. This study aims to investigate the association between alcohol usage and knowledge of cardiovascular diseases (CVDs) risk factors among Ellisras rural adolescents and young adults aged 14-22 years. In this cross-sectional study a total of 1409 subjects (736 boys and 673 girls), aged 14-22 years, from the Ellisras Longitudinal Study, South Africa completed a validated alcohol use and CVDs knowledge questionnaire. Logistic regression was used to estimate the association. The prevalence of alcohol intake increased with increasing age among girls (13.6% to 17.7%) and boys (10.3% to 16.9%) and reached a statistically significant difference ( < 0.024) at an older age category (20-22 years). There was a significant ( < 0.05) association between alcohol use and a positive response on the following knowledge statements: The fact that cardiovascular disease attacked all age groups and mostly elderly people (the odds ratio (OR) ranged between 0.5 95% confidence interval (CI) = 0.33-0.74 and OR = 2.86 95% CI = 1.27-6.42). Medical doctors can help to diagnose somebody with cardiovascular diseases (OR ranged between 2.25 95% CI = 1.49-3.39 and OR = 0.75 95% CI = 0.65-0.87). The condition for cardiovascular diseases developed over a long period (OR ranged between 1.75 95% CI = 1.16-2.64 and OR = 2.23 95% CI = 1.34-4.07). The prevalence of alcohol use in Ellisras rural adolescents and young adults begins between the ages of 14 and 16 years and increases with age. Binge drinking was more evident on Fridays and Saturdays among the Ellisras rural adolescents and young adults with girls showing a significantly higher prevalence of binge drinking compared to boys on a Friday.
