According to the National Health and Nutrition Examination Survey in 2007, nearly half of all American children are either overweight or obese. Retrospective chart review identified patients with the diagnostic codes for overweight, obese, and/or excessive weight gain. Inclusion criteria were current age between 2 and 20 years, a minimum of 5 visits with weight and height measurements, and a body mass index (BMI) at or above the 85th percentile. A total of 184 patients met inclusion criteria. More than half the children became overweight before age 2, and all patients were obese or overweight by age 10. The rate of gain is approximately 1 excess BMI unit/year, therefore causing most children to be overweight by age 2 (R (2) = .53). This study indicates that the critical period for preventing childhood obesity in this subset of identified patients is during the first 2 years of life and for many by 3 months of age.
根据2007年美国国家健康与营养检查调查，几乎一半的美国儿童超重或肥胖。回顾性病历审查确定了患有超重、肥胖和/或体重过度增加诊断代码的患者。纳入标准为当前年龄在2至20岁之间，至少有5次体重和身高测量记录，且体重指数（BMI）处于或高于第85百分位。共有184名患者符合纳入标准。超过一半的儿童在2岁前超重，所有患者在10岁时均为肥胖或超重。体重增加速率约为每年1个超重BMI单位，因此导致大多数儿童在2岁时超重（R² = 0.53）。这项研究表明，在这一已确定患者亚组中，预防儿童肥胖的关键时期是在生命的头两年，对许多儿童来说是在3个月大时。
