TABLE 1.
Baseline characteristics of and 5-y follow-up observations in individuals with and without a binge-eating disorder at baseline1
| Characteristic | Binge-eating disorder (n = 134) | No binge-eating disorder (n = 134) | P2 |
| Baseline age (y) | 47.0 ± 13.23 | 47.8 ± 12.9 | 0.56 |
| Female sex [n (%)] | 107 (80) | 102 (76) | 0.56 |
| Race-ethnicity [n (%)] | |||
| White, non-Hispanic | 119 (89) | 129 (96) | 0.034 |
| African American | 14 (10) | 5 (4) | |
| Hispanic | 1 (1) | 0 | |
| Baseline BMI (kg/m2) | 36.1 ± 7.5 | 34.5 ± 5.7 | 0.046 |
| Follow-up time (mo), median (interquartile range)4 | 61.0 (60.1, 62.2) | 60.8 (59.8, 62.4) | 0.48 |
| Change in BMI over follow-up interval (kg/m2) | 0.0 ± 4.9 | 0.5 ± 3.6 | 0.33 |
Of the 137 individuals with binge-eating disorder seen for at least one follow-up visit, 3 were excluded from analysis because they already had a diagnosis of all 3 metabolic syndrome components at baseline; for the individuals without binge-eating disorder, the number is reduced from 138 to 134 for the same reason.
P values from t test for continuous variables (except follow-up time), Fisher's exact test for categorical variables, and Wilcoxon's rank-sum test for follow-up time; all tests were 2-tailed.
Mean ± SD (all such values).
All participants were evaluated at the 2.5-y follow-up, and 96% were evaluated at both 2.5 and 5 y.
