Recent Trend and Associated Factors of Harmful Alcohol Use Based on Age and Gender in Korea.

Abstract

BackgroundPrevious studies suggest that the impact of social factors on harmful alcohol use between men and women may be different. We aimed to explore the gender-based difference in temporal trend and social risk factors associated with harmful alcohol use.MethodsThe Korea National Health and Nutrition Examination Survey (2007–2014) was used to explore the recent trend of harmful alcohol use in the general population. Among all current alcohol drinkers aged 20–64 years, the frequencies of harmful alcohol use in each age group, year of birth, marriage, income, education, and occupation were analyzed based on gender.ResultsA total of 34,478 people (14,544 men and 19,834 women) who reported drinking alcohol in the last month at the time of interview were included in the analysis. The proportion of harmful alcohol use in men decreased (P for trend = 0.002) during the study period, whereas significant change was not observed in women (P for trend = 0.173). The prevalence of harmful alcohol use was highest in men aged 35–49 years and women aged 20–34 years. For both men and women, lower level of education and service occupation were the common risk factors of harmful alcohol use. Additionally, low income was a risk factor of harmful alcohol use in women but not in men. Marriage increased the risk of harmful alcohol use in women but decreased in men.ConclusionPublic health interventions in reducing harmful alcohol use should consider the different high-risk groups between men and women.
