BACKGROUND:Harm from alcohol-attributable aggression and violence is linked to diminished personal safety and reduced physical and mental health and wellbeing in many countries. But there has been limited evidence on these harms in low- and middle-income countries (LMICs). This study measured harm from others' drinking-related aggression, violence and misconduct in five Asian LMICs (Thailand, Sri Lanka, India, Vietnam, and Lao PDR), aiming to compare the magnitude and pattern of harm across countries by gender, age group, educational level, rurality, and country-level indicators. METHODS:Data from 9832 respondents from the WHO/Thai Health International Collaborative Research Project on the Harm from Others' Drinking undertaken between 2012 and 2014 were analysed. FINDINGS:50-73% of respondents from five countries reported being harmed at least once in the past year. Public disorder and feeling unsafe due to someone else's drinking was frequently reported, followed by harassment, assaults and threats, traffic harm, and property damage. In most countries, men were more likely than women to report traffic harms, property harm, and assaults, whereas women were more likely to report feeling unsafe in public. Being young, less educated, living in urban areas, and one's own drinking were significant predictors of more harm from others' drinking for both genders. CONCLUSIONS:This study revealed a consistently high prevalence of alcohol-related aggression and violence in the five Asian countries. Patterns of harm within countries and populations at most risk for different forms of harms were identified. Alongside services for those affected, efforts to strengthen alcohol policies are needed in each society.
