Prevalence of alcohol use disorder among individuals who binge eat: a systematic review and meta-analysis.

Binge eating disorder (BED) is correlated with substance use. This study aimed to estimate the life-time prevalence of alcohol use disorder (AUD) among individuals with non-compensatory binge eating and determine whether their life-time prevalence of AUD is higher than in non-bingeing controls. A systematic search of databases (PubMed, Embase and Web of Science) for studies of adults diagnosed with BED or a related behavior that also reported the life-time prevalence of AUD was conducted. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol was followed. The protocol was registered on the International Prospective Register of Systematic Reviews (PROSPERO). Studies originating in Canada, Sweden, the United Kingdom and the United States. Eighteen studies meeting the inclusion criteria were found, representing 69 233 individuals. Life-time prevalence of AUD among individuals with binge eating disorder and their life-time relative risk of AUD compared with individuals without this disorder. The pooled life-time prevalence of AUD in individuals with binge eating disorder was 19.9% [95% confidence interval (CI)=13.7-27.9]. The risk of life-time AUD incidence among individuals with binge eating disorder was more than 1.5 times higher than controls (relative risk=1.59, 95% CI=1.41-1.79). Life-time AUD prevalence was higher in community samples than in clinical samples (27.45 versus 14.45%, P=0.041) and in studies with a lower proportion of women (β=-2.2773, P=0.044). Life-time alcohol use disorder appears to be more prevalent with binge eating disorder than among those without.

Prevalence of alcohol use disorders in mainland China: a systematic review.

AimsTo identify studies about the prevalence of alcohol use disorder (AUD) in mainland China, evaluate the quality of these studies and conduct a meta‐analysis of the prevalence of AUD in China's adult population and in population subgroups defined by sex, age and urban versus rural residency.MethodsRelevant studies published prior to January 2014 were identified from the following databases: China Knowledge Resource Integrated (CNKI), Wanfang, Pubmed, EmBase and Web of Science. A 16‐item quality assessment inventory for epidemiological studies in mainland China was constructed to evaluate the methodological rigor of the studies. A total of 38 studies including 1 304 354 individuals were identified. Outcomes included current and life‐time prevalence of AUD, alcohol dependence and alcohol abuse.ResultsThe pooled life‐time and current prevalence of alcohol dependence were 1.4% [95% confidence interval (CI) = 1.3, 1.5] and 1.5% (95% CI = 1.2, 1.9). For males, pooled estimates of the current prevalence of alcohol dependence, alcohol abuse and AUD were 4.4 (95% CI = 3.1, 5.7), 4.0 (95% CI = 2.2, 5.7) and 10.1% (95% CI = 4.7, 15.4), respectively; the corresponding values for females were all below 0.2, 0.1, and 0.1%. There was large between‐study heterogeneity in the prevalence measures that was associated with sample size, the use of key informants and the use of substitute respondents. The quality of included studies was generally low. Higher‐quality studies reported higher prevalence.ConclusionsAlcohol use disorder is an urgent public health problem in China, especially among males. When using high‐quality studies, current and life‐time prevalence estimates of alcohol dependence in China measure 2.2% and 3.7%, respectively, approaching those of the Netherlands, United States and other western countries.
