Inter-ethnic differences in self-reported alcohol-related harm to children in Han vs. Yi ethnic minority households in Yunnan Province, China.

China is a multi-ethnic country, but inter-ethnic disparities in alcohol-related harm to children have not been described. In this study, we assessed differences in prevalence of self-reported alcohol-related harm to children in Yi and Han households in Chuxiong Yi Prefecture, Yunnan Province, China. We conducted a cross-sectional study among caregivers in households with a child age less than 18 years using structured questionnaire interview. Participants included 241 Yi caregivers and 610 Han caregivers (overall refusal rate = 1.1%). Heavy drinking was more common in Yi households than Han households (41.9% vs. 30.8%, respectively), but there was no difference in alcohol-related harm to children (21.2% vs. 17.9%; Adjusted OR = 0.98; 95% CI = 0.65, 1.46). Caveats such as social desirability in reporting sensitive issues and the cross-sectional study design should be considered in the interpretation of the study findings.
