Trends in relative weight over 1 year in low‐income urban youth

Objectives Recent cross‐sectional data indicate the rates of childhood obesity are plateauing. Few large‐scale longitudinal data sets exist, particularly in low‐income and minority youth. The purpose of this study was to describe longitudinal changes in relative weight among a large sample of low‐in...

Description
Summary:Objectives Recent cross‐sectional data indicate the rates of childhood obesity are plateauing. Few large‐scale longitudinal data sets exist, particularly in low‐income and minority youth. The purpose of this study was to describe longitudinal changes in relative weight among a large sample of low‐income, minority youth over 1 year. Methods Participants were students from 56 schools in urban, low‐income environments. There were 17,727 first‐ to sixth‐graders (64% African–American, 52% male) assessed at baseline, and 13,305 youth (75.1%) were reassessed 1 year later at follow‐up. Measured height and weight were used to assess categorical (overweight, obesity, severe obesity) and continuous (BMI, percentile, z‐score) measures of relative weight. Results Longitudinal data showed that over 1 year, BMI percentile (95% CI.64‐–0.32, P
