The objective of this study was to compare the prevalence of overweight and obesity in children from northwest of Mexico based on BMI/age and three criteria of growth reference standards. Six hundred and four children, 6 to 10 years of age, from 17 municipalities of the state of Sonora were measured for weight and height and age established from birth certificate school records. The prevalence of overweight and obesity was determined by the new version of the US Centers for Disease Control and Prevention (CDC/NCHS), the International Obesity Task Force (IOTF) and the values proposed by The World Health Organization (WHO) that was utilized in the National Nutrition Survey of 1999 in Mexico (ENN). Using the WHO reference, prevalence of overweight and obesity was 39%. This was higher than the CDC/NCHS (20%) and IOTF (17%) references, respectively. Prevalence of overweight and obesity by CDC/NCHS and IOTF criteria, showed the best agreement (Kappa >80); this was not the case when prevalence from CDC/NCHS and IOTF were compared to the WHO criteria (Kappa <40). For overweight and obesity frequencies, no sex or urban-rural differences were observed (p>0.05). In conclusion, the use of these 3 reference values systems using BMI/ age did not show the same prevalence estimates of overweight and obesity. The use of the WHO method can overestimate the prevalence of obesity in children, therefore the use of these 3 references should be considered for future comparisons.
本研究的目的是根据BMI/年龄以及三种生长参考标准，比较墨西哥西北部儿童超重和肥胖的患病率。对来自索诺拉州17个市的604名6至10岁儿童进行了体重、身高测量，并根据出生证明和学校记录确定年龄。超重和肥胖的患病率是根据美国疾病控制与预防中心（CDC/NCHS）的新版本、国际肥胖特别工作组（IOTF）以及世界卫生组织（WHO）在1999年墨西哥全国营养调查（ENN）中使用的值来确定的。使用WHO的参考标准，超重和肥胖的患病率为39%。这分别高于CDC/NCHS（20%）和IOTF（17%）的参考标准。根据CDC/NCHS和IOTF标准得出的超重和肥胖患病率显示出最佳一致性（Kappa>80）；而将CDC/NCHS和IOTF的患病率与WHO标准进行比较时则并非如此（Kappa<40）。对于超重和肥胖的频率，未观察到性别或城乡差异（p>0.05）。总之，使用这三种基于BMI/年龄的参考值系统得出的超重和肥胖患病率估计值并不相同。使用WHO的方法可能会高估儿童肥胖的患病率，因此在未来的比较中应考虑使用这三种参考标准。
