Differential Associations Between Excess Body Weight and Psychiatric Disorders in Men and Women

Abstract

Background: The current investigation is the first large-scale population-based study from France that documents the association between excess body weight and common psychiatric disorders, and examines the influence of gender on the association between excess body weight and these disorders. A recent plan has been implemented in France to treat the rising rate of those who are overweight or obese, and we seek to demonstrate whether integrated treatment of excess weight and psychiatric conditions appears as indicated.

Materials and methods: Data were drawn from a cross-sectional general population survey of 17,237 adults. Past-year psychiatric disorders were assessed using the Composite International Diagnostic Interview-Short Form. Body mass index was used to determine excess weight status.

Results: Overall, 3.7% of the sample were underweight, 57% were normal weight, 28% were overweight (35% of men, 22% of women), and 11% were obese (11% of men, 11% of women). Being overweight was more common in men than women, although obesity did not differ by gender. Sociodemographic variables significantly associated with weight status included, age, marital status, education, employment status, income level, and population density. Adjusting for these variables, being overweight was associated with major depression and other disorders among women and inversely associated with drug abuse and dependence among men. Obesity was associated with major depression, panic disorder, agoraphobia, social phobia, specific phobia, and obsessive-compulsive disorder among women. Only generalized anxiety was associated with obesity among men.

Conclusion: Past year, mental disorders were more likely associated with being overweight or obese among women as compared with men. The prevalence of these co-occurring psychiatric disorders in the context of the rising rate of obesity in France indicates a clear need for psychiatric assessment and treatment in caring for those with excess weight, especially women. Preliminary reports suggest this need is unmet within the otherwise progressive move in France to assist those struggling with excess weight.
