TABLE 3.
Energy intake, physical activity, and body weight by tertile of baseline dietary energy density (food only)a
| Baseline dietary energy density (food only) |
|||
|---|---|---|---|
| Variable | Bottom tertile (<1.29 kcal/g) | Middle tertile (1.29−1.60 kcal/g) | Top tertile (≥1.61 kcal/g) |
| Total energy intake (kcal/day)b | 1,571 ± 12.9 | 1,698 ± 12.9* | 1,874 ± 12.6† |
| Physical activity (METs/week)b,c | 1,101 ± 29.6 | 903 ± 29.4* | 637 ± 22.9† |
| Body weight (kg)b | 70.1 ± 0.56 | 72.8 ± 0.55* | 76.9 ± 0.55† |
a
n = 2,713 (intervention and control group combined). Reference: bottom tertile; values with different symbols (*, †) are significantly different (P< 0.05). 1 kcal = 4.18 kJ. Abbreviation is as follows: METs, metabolic equivalent tasks.
b
Mean ± standard error of the mean.
c
Sum of METs assigned as 2 METs/min of casual strolling, 3 METs/min of mild activity or average walking, 4 METs/min of fast walking, 5 METs/min of moderate activity, 6 METs/min of very fast walking, 8 METs/min of strenuous activity.
