Characteristics of obese children aged 1-4 years at a referral clinic.
OBJECTIVE
To describe characteristics and indicators of nutritional status of young, obese children.


METHODS
Medical records of 135 children aged 1-4 years seen in an urban referral setting between January 2000 and June 2006 were reviewed. Characteristics associated with severe obesity [percent ideal body weight (%IBW) > or = 160%] were determined. Relationships between %IBW, weight-for-height Z score (WHZ), body mass index (BMI) and BMI Z score (BMIZ) were evaluated. Receiver operating characteristic analyses evaluated BMI values classifying severe and moderate (140-159% IBW) obesity.


RESULTS
Children were: 41% male, 71% Hispanic, 76% Medicaid/uninsured, 64% ever breastfed, had median BMI of 25.0 kg/m2 and median %IBW of 159. Fifty-two percent of mothers had BMI > or = 30 kg/m2. Severely obese children more frequently had an obese mother, birthweight > or = 4 kg, were older, male, never breastfed and reported higher juice intake. WHZ and BMIZ were lowest at 4 years; BMI and %IBW were lowest at 1 year. %IBW and BMI were highly correlated. BMI > or = 22.2 kg/ m2 indicated moderate obesity (sensitivity = 0.90, specificity = 0.93), and BMI > or = 25.0 kg/m2 indicated severe obesity (sensitivity = 0.97, specificity = 0.92).


CONCLUSIONS
Few current health behaviors and many family or past risk factors were associated with degree of obesity. %IBW and BMI may be the most useful nutritional status measures to track progress in young, obese children.
