To describe the problem of obesity in Mexican American children and provide a method for identifying Mexican American children at risk for obesity.
Cross-sectional and retrospective cohort study.
Mexican American children, ages 5-11 (kindergarten (K) - 5th grade) were studied in cross-sectional (girls=463, boys=448) and retrospective (girls=124, boys=92) samples.
Weights (kg) and heights (cm) were extracted from each child's school medical records.
Measurements were made by the school nurses (one nurse per school).
Body mass index (BMI [w/h2]) was calculated from obtained weights and heights.
The prevalence of obesity in the cross-sectional sample was 27.4% for girls and 23.0% for boys.
The highest prevalence was noted in 4th grade for both the girls (32.4%) and boys (43.4%). The 5 year incidence rates derived from the retrospective sample were 17.7% for girls and 21.1% for boys.
The largest increase in the number of girls becoming obese was observed between K and 1st grade (15.6%), The largest increase for boys was found between the 1st and 2nd grades (13.2%). Logistic regression parameters were calculated to estimate the probability of becoming obese in 5th grade given a child's K BMI.
Using the generated equation, BMls in K equal to 16.5,20.9, and 23.7 would have a 21.0%, 70.0%, and 91.0% probability of being obese by 5th grade. (...)
