A score of ORWELL-97 above the 75° percentile or a Z-score of individual domains of SF-36 and PGWB lower than -1.0 were the dependent variables. Data are presented as odds ratio (95% confidence intervals) for any 1-point increase in BMI class and in the scores of somatic and mental disease, binge eating and weight history (see Materials & Methods for calculations). All data are adjusted for age, gender and BMI.
°Significantly higher in females than in males (P < 0.05).
*P < 0.001; † P < 0.05 for the significance of association.
