Prevalence and Trends of Obesity among Chinese Korean Nationality Children and Adolescents, 1991–2010
Background: Obesity has become a serious problem for Chinese Han nationality. This research aimed to evaluate the prevalence of and trends in obesity among Chinese Korean nationality children and adolescents (1991–2010).
Methods: We used data from Chinese National Surveys on Students’ Constitution and Health (CNSSCH). CNSSCH was utilized to monitor Chinese students’ health condition and released its data every 5 yr (1991, 1995, 2000, 2005 and 2010). The standard weight-for-height was the 80th percentile for sex- and age-specific growth charts based on the 1985 CNSSCH data. Obesity was defined as ≧120% of standard weight-for-height.
Results: The total age-adjusted prevalence of obesity was 15.9% (95% confidence interval (CI), 14.9-16.9%) among Chinese Korean children and adolescents aged 7 to 18 yr. Children or adolescents who were boys (Rate ratios (RR), 1.35; 95% CI, 1.19–1.53) or aged 10–12 (RR, 1.38; 95% CI, 1.17–1.63) were more likely to be obese. The trend analysis of the 19-yr period implied a serious annual increasing trend during 1991-2000 (RR, 1.05; 95% CI, 1.02–1.07) and during 2000-2010 (RR,, 1.12; 95% CI, 1.11–1.13). Chinese Korean children may also be more likely to become obese than Han nationality children during 1991-2010.
Conclusions: A serious and continuous increasing trend was in the prevalence of obesity among Chinese Korean children and adolescents during 1991–2010. Childhood obesity had become a serious problem. This prognosis is worrisome.
