Alcohol's harm to others and subjective well-being: Cross-sectional studies in Lao People's Democratic Republic and Thailand

Introduction and aims: Previous studies have confirmed that the number of heavy drinkers in a household negatively correlates with the subjective well-being of individuals in the household. However, limited studies have investigated the experiences of alcohol's harm to others (HTO) and subjective well-being, particularly in low- and middle-income countries. The purpose of this study was to investigate the associations between experiences of HTO and subjective well-being in two selected low- and middle-income countries.

Design and methods: We analysed population survey data on 1205 and 1491 individuals aged 18-64 years from Lao People's Democratic Republic (Lao PDR) and Thailand, respectively. The respondents' experiences of HTO and their subjective well-being were measured using face-to-face interviews. The association between experiencing HTO and subjective well-being was investigated using Tobit regression models.

Results: A significant association between experiencing HTO and subjective well-being was found in Thailand, but not in Lao PDR. Those who had ever experienced HTO had a 2.77-point lower score of subjective well-being than those who had never experienced HTO (95% confidence interval -4.67, -0.88; P-value <0.05) in Thailand. In Lao PDR, the physical harm dimension showed the strongest association with subjective well-being compared to other types of harm, while in Thailand, financial harm was the dimension most strongly associated with the outcome.

Discussion and conclusions: There was a significant association between HTO and subjective well-being, particularly physical harm in Lao PDR and financial harm in Thailand. The study suggests that services to mitigate the impacts of HTO on well-being should focus on physical harm in Lao PDR and financial harm in Thailand.
