Trends in inequalities of alcohol-related harms among Thai households: 2007-2017

Abstract

BackgroundTo estimate and compare the socio-economic inequities in alcohol-related harms among households in Thailand between 2007 and 2017 adjusted for socioeconomic status with the proportions of current and binge drinkers in each household. MethodsA secondary data analysis of the 2007 and 2017 National Cigarette and Alcohol Consumption Survey was conducted. The unit of analysis was household-level. Concentration index (CI) was used to measure household income-based inequalities in alcohol-related harms (i.e., workplace, domestic, non-domestic, financial, and drinking-and-driving) in the previous 12 months. ResultsBased on data from two waves of survey (n = 66,776 in 2007 and 39,630 in 2017), the prevalence of households that had at least one member who had an alcohol-related harm event was 21.8% and 26.2% in 2007 and 2017, respectively. The highest prevalence was the drinking-and-driving domain (about 20%). The prevalence increased between 2007 and 2017 with an annual rate of change ranged from 1.2 to 4.4%. All of the CI values were negative for both survey waves, except the drink-and-driving domain in 2007. The CI values for all domains in 2017 had a larger magnitude than in 2007, except the domestic domain. For any alcohol-related harm, the CI value was not significant at +0.002 (Standard error [SE] 0.004) in 2007, but significant at -0.014 (SE 0.004) in 2017. So, the index changed around -0.016. ConclusionsThe poor households had a slightly greater tendency to incur harms from alcohol and there existed more inequality in the prevalence of harms in 2017 compared with 2007.
