Extreme-group-comparison of food addiction intensity in the highest and lowest quartiles of leptin serum levels.
| Quartiles | Leptin serum levels in pg./ml | Mean YFAS scores (SD) (range) | N | |||
|---|---|---|---|---|---|---|
| Men | Women | Men | Women | Men | Women | |
| Lowest: < | 2.705 | 8.20 | 1.18 (0.65) (0–4) | 1.22 (0.62) (0–3) | 132 | 95 |
| Highest: > | 7.99 | 24.19 | 1.55 (0.98) (0–7) | 1.53 (1.03) (0–5) | 133 | 97 |
| --- | --- | --- | Z = −3.806a p = 0.0001 *** | Z = −1.529a p = 0.126 | --- | --- |
SD, Standard Deviation; YFAS, Yale Food Addiction Scale (39). +p < 0.10; *p < 0.05; **p < 0.01; ***p < 0.001. aA Mann–Whitney U test was performed to assess group differences in YFAS scores due to non-normal distribution of the dependent variable (Kolmogorov–Smirnov-Test: p < 0.05).
