• Description:
  Objective
  
  Recent cross-sectional data indicate the rates of childhood obesity are plateauing. Few large-scale longitudinal datasets exist, particularly in low-income and minority youth. The purpose of the current study was to describe longitudinal changes in relative weight among a large sample of low-income, minority youth over one year.
  
  Methods
  
  Participants were students from fifty-six schools in urban, low-income environments. There were 17,727 1st-6th graders (64% African American, 52% male) assessed at baseline and 13,305 youth (75.1%) were reassessed one-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 one year, BMI percentile (95% CI: −0.64 – −0.32,p<.001) and BMI z-score (95% CI: −0.02 – −0.01,p<.001) were significantly lower compared to baseline. The prevalence of overweight and obesity was stable over one year. Most (86.0%) youth remained in the same weight category as baseline, 6.8% improved weight category and 7.2% worsened weight category over one year.
  
  Conclusions
  
  These longitudinal data indicate that the relative weight of low-income, urban youth is showing signs of a small improvement over a one year follow-up period. The rates of childhood obesity, however, remain remarkably high and require continued, creative, public health efforts.
