Drinking behaviors of Chinese adolescents over the past three decades: A systematic review and meta-analysis.

Adolescent drinking is a major worldwide public health challenge. China is home to the world's second largest youth population, but relatively little is known about adolescent drinking behaviors. This study examined (1) prevalence rates and sex and age differences in drinking behaviors among Chinese adolescents over the past three decades and (2) whether underage drinking declined following the enactment of a strict national underage drinking policy in 2006. Literature search was conducted in one Chinese and five English databases following the PRISMA guidelines. A total of 186 studies were included in the meta-analyses using random-effects models on nine measures (Ns range: 13,489-755,796, number of studies range: 12-110): lifetime, past month, past year, and weekly drinking; lifetime, past year, and past month drunkenness; past month binge drinking, and age at first drinking (≤ 13 years). Males reported higher prevalence on all drinking behaviors except for weekly drinking and past month drunkenness. High school students reported higher prevalence in lifetime drinking, past year drunkenness, and lifetime drunkenness, than middle school students. No measured drinking behavior showed a significant or reliable decline after 2006. The findings suggest that prevalence rates of drinking behaviors remain high among Chinese adolescents but are lower than among European or North American adolescents. The 2006 Chinese national policy to reduce underage drinking did not measurably alter patterns of underage drinking. Implications for prevention, research, and policy are discussed.
