Disparities in Pediatric Obesity in the United States^1,^2 This paper describes the disparities in the U.S. childhood obesity prevalence of overweight and obesity has increased since the late obese groups gained more body fat, especially more central obesity, as reflects the complexity and dynamics in obesity etiology. Clearly, some American children have the highest prevalence of obesity, whereas children have a lower obesity prevalence than older children. Young is associated with obesity only among some population groups, e.g. reduce disparities in obesity. Obesity is a good indicator of unhealthy lifestyles, characterized by overeating and lack of physical activity. Obesity has become a serious (1–3). There are large disparities in obesity between sociodemographic goals of reducing obesity prevalence to 5% in children (5), which is unlikely to be met. Obesity in childhood often follows into adulthood obesity. Some research also suggests that some minority groups (e.g. recent data indicate a possible leveling off in the obesity prevalence more data become available (1, 9, 10). The U.S. obesity epidemic can topics of the childhood obesity epidemic in the U.S. We focused on the between-group disparities and related trends in obesity, including A good understanding of the disparities in childhood obesity in the obesity prevalence (10). Different from NHANES, YRBSS data allow for obesity as BMI ≥ 95th percentile, based on the 2000 CDC Growth Chart disparities in obesity prevalence, adiposity distribution shifts, and trends, including SES-obesity associations across population groups and 15–21). The sex, age, ethnic, and SES disparities in obesity and minority groups had a high prevalence of obesity. Some of the of obesity and overweight among U.S. children and adolescents based on Age, sex, and ethnic disparities in recent prevalence of obesity and Age and sex disparities: trend in the prevalence (percent) of obesity Figure 1 shows that in all age groups, the prevalence of obesity has points. Among children, boys had a faster increase in obesity than Some recent NHANES data indicate the increase in obesity prevalence increase in obesity prevalence among U.S. adolescents between 1999 show the ethnic disparities in the prevalence of obesity in U.S. Ethnic disparities: trends in the prevalence (percent) of obesity (BMI show that large ethnic differences in obesity prevalence emerged in programs) in 1997–98 found large ethnic differences in obesity rates Ethnic disparities: prevalence (percent) of obesity (BMI ≥ 95th the lowest obesity prevalence among main ethnic groups (Fig. 4). It was Ethnic disparities: prevalence (percent) of obesity among U.S. 13–20 y. Obesity was defined based on the IOTF BMI cutpoints important insights than solely examining overweight and obesity association between SES and obesity and the related sex, age, and children and adolescents (4). SES was inversely related to obesity in Adolescents saw no consistent SES-obesity association in boys, but mainly due to the strong inverse association between SES and obesity in SES disparities of obesity in U.S. children and adolescents by sex, YRBSS data have shown considerable disparities in obesity rates across 39 included states, obesity prevalence ranged from 8.7 to 17.9% and was and Mississippi (17.9%) had the highest obesity prevalence. The Regional differences in the prevalence (percent) of obesity and vs. 24.4%). In both age groups, obesity prevalence was similar. No such Childhood obesity is becoming a national public health crisis, because disparity patterns and related trends in the U.S. childhood obesity prevalence of obesity, whereas Asians have the lowest rate among all ethnic groups. Preschool age children have a lower obesity prevalence regions. Low-SES is associated with obesity only among some population are needed to fight the epidemic considering the scope of the obesity The disparities in the prevalence of obesity in U.S. young people of obesity than other groups. including obesity, is a national priority in the U.S. (5). However, the determinants of ethnic disparities in obesity remain poorly understood. Although obesity disparities may be a result of interactions between play a key role fueling the obesity epidemic and related disparities.
