BACKGROUND: The current work aimed to investigate the mediating role of adiposity traits in the relationship between eating behaviors, sleep quality, socio-demographic factors, and the health-related quality of life in women of reproductive age in northwest of Iran. METHODS: In the current cross-sectional study, a total of 278 overweight and obese women of reproductive age (20-49 y) were enrolled. Anthropometric assessments were performed. Pittsburgh sleep quality index (PSQI) was used for assessment of sleep quality while Short Form 36 (SF-36) questionnaire was used to measure health-related quality of life (HRQoL). Three-Factor Eating Questionnaire-R18 (TFEQ-R18) was used to measure eating behaviors. Path analysis was used to test the relationships between parameters. RESULTS: Age was found to be indirectly and negatively associated with mental component score (MCS) (B = - 0.040; P = 0.049) and physical component score (PCS) (B = - 0.065; P = 0.036) through mediatory effects of obesity. Additionally, education was seen to be indirectly and positively related to MCS (B = 0.529; P = 0.045) and PCS (B = 0.870; P = 0.019), respectively. On the other hand, obesity (B = 0.608; P = 0.018) and PSQI score (B = - 0.240; P = 0.034) had direct associations with MCS. Age (B = - 0.065; P = 0.036) and education (B = 0.870; P = 0.019) were also directly associated with obesity. CONCLUSIONS: Obesity seemed to mediate the effects of socio-demographic parameters on HRQoL. Poor sleep quality was also related to impairment of HRQoL. Further studies are needed to confirm these results.
