Table 2.
Summary of time-related break points with best fit (lowest AIC) based on single breakpoint linear spline models a
Race-Sex | Time of break point | Slope before break point | Slope after break point | Change in slopes | p-value | Fit statistic (AIC) |
---|---|---|---|---|---|---|
Black women | Year 10 | 0.55 | 0.02 | −0.53 | <.0001 | 46316.21 |
White women | Year 15 | 0.44 | 0.14 | −0.30 | <.0001 | 41698.27 |
Results are presented for race-sex groups with significant quadratic trends for time-related weight gain.
