Table 4 Logistic regression of potential obesogenic and leptogenic child and maternal variables based on marked changed in body mass index percentile (≥ ± 10 percentiles per year), odds ratios (95 % confidence interval)

From: How has child growth around adiposity rebound altered in Scotland since 1990 and what are the risk factors for weight gain using the Growing Up in Scotland birth cohort 1?

  1. *p < 0.05, Q = quintile
  2. No change defined as those in the healthy weight category in sweep 4 and not demonstrating any marked change in percentile across the three sweeps. Obesogenic defined as those in the healthy weight, or overweight categories in sweep 4 showing marked increases in percentile across the three sweeps. Leptogenic defined as those in the obese or overweight categories in sweep 4 showing marked decreases in percentile (excluding those becoming underweight) across the three sweeps
