Distribution of obesity risk factors in two independent samples.

Characteristics of the samples by body mass index.
Figure 1.
Regression lines comparing the calculated per kg/m2 decrease in BMI per year of educational attainment in Study 1 females, where BMI is represented along the Y-axis and reported educational attainment is represented along the X-axis.
Data adjusted for age, race, physical activity, parental adiposity, and diet. Individual slopes significantly different from zero at p<10−6.
Figure 2.
Percentile plot showing the slope for BMI vs. years of education (Y-axis) at each percentile of the BMI distribution (X-axis).
For example, each addition year of education in Study 1 females was associated with a BMI decrease of (slope±SE) −0.117±0.018 kg/m2 at the 10th percentile of their BMI distribution (A), −0.117±0.016 kg/m2 at their 25th percentile (B), −0.165±0.020 kg/m2 at their 50th percentile (C, the median), −0.245±0.029 kg/m2 at their 75th percentile (D), and −0.300±0.046 kg/m2 at their 90th percentile (E, compare with Figure 1). The dashed lines designate one standard error. Data adjusted for age, race, physical activity, and diet. Study 1 included additional adjustment for parental adiposity.
Figure 3.
Percentile plot showing the slope for BMI vs. the dietary index (high-meat/low-fruit content, Y-axis) at each percentile of the BMI distribution (X-axis).
The exact definitions of the dietary indices are described in the Methods Section. The dashed lines designate one standard error. Data adjusted for age, race, and education. Study 1 included additional adjustment for parental adiposity.
Figure 4.
Percentile plot showing the slope for BMI vs. parental adiposity (Y-axis) at each percentile of the BMI distribution (X-axis).
The dashed lines designate one standard error. Data adjusted for age, race, education, physical activity, and diet.
