Objective: To investigate the associations between obesity and self-rated health and psychological well-being in Spanish women. Design: Cross-sectional study. Three dependent variables were defined: self-rated health; self-declared diagnosis of psychiatric disorders or use of psychiatric drugs; and General Health Questionnaire-12 (GHQ-12) score. A set of variables (sociodemographic, morbidity and lifestyle) were used to adjust for possible confounding effects. Setting: The National Health Survey was conducted in Spain in 2006. Subjects: A total of 15 099 women aged $18 years. Participants were classified into groups according to their BMI. Results: In all, 55?4 % of the women had normal weight, 29?4 % were overweight and 15?2 % were obese. Self-perception of poor health in obese women was 57?8 %, a significantly higher value than in women of normal weight (28?8 %). Prevalence of psychiatric disease was 35?5 % in obese women and 18?9 % in women of normal weight. In multivariate analysis, obese women had 34 % higher odds of declaring poor self-perception of health (OR 5 1?34; 95 % CI 1?12, 1?61), 18 % higher odds of self-reporting psychiatric disease (OR 5 1?18; 95 % CI 1?02, 1?38) and 26 % higher odds (OR 5 1?26; 95 % CI 1?02, 1?55) of having an abnormal outcome ($3) on the GHQ-12 than women of normal weight. Conclusions: The present study highlights that obese Spanish women have worse self-rated health and psychological health than those with normal weight. These aspects are relevant because of the growing importance placed on the functionality of patients and their mental health within the obesity epidemic.

Obesity and overweightSelf-rated health Psychological distress Psychiatric diseases General Health WHO has defined obesity as a 21st century epidemic because of its proportions over recent decades and its overwhelming impact on morbidity and mortality and quality of life. Thus, obesity presents a significant challenge to public health (1)(2)(3)(4) . Obesity is associated with many factors aside from the purely biological ones. Previous studies have shown demographic and socio-economic influences on the prevalence of weight problems (5) . The greater prevalence of obesity in groups with a lower socio-economic status and those with associated comorbidity (5,6) is noteworthy. In Europe, the prevalence of obesity ranges from 5 % to 23 % among men and between 7 % and 36 % among women (7) . In Spain, overall, prevalence is estimated at 15?5 % in adults, higher in women (17?5 %) than in men (13?2 %) (1) . In previous studies, it has been described that obesity is more prevalent in women (5,6,8) . In addition, it has been found that women suffer more psychiatric disorders (9,10) , musculoskeletal disorders (8) and CVD (11) than do men, with this difference being even greater when the women are also obese (4,12) . Furthermore, scientific literature reports poor self-rated health more frequently in women than in men (13)
