RELAÇÃO BILATERAL ENTRE EXCESSO DE PESO E TRANSTORNOS MENTAIS

Abstract

Objective: To determine the prevalence of excess weight in individuals with and without mental disorders. Methods: A cross-sectional, quantitative and analytical study carried out with 167 adult volunteers of both sexes, with and without mental disorders, and aged over 18 years, in the period from October to December 2015. The participants were recruited at the Psychosocial Care Center and at a Basic Health Unit of Teresina, Piaui, Brasil. A structured form was used to collect sociodemographic variables (age, sex, schooling, marital status and income) and anthropometric variables (weight and height). The anthropometric diagnosis was determined by the Body Mass Index, and the psychiatric diagnosis was according to the International Classification of Diseases (ICD 10). The data analysis was performed in a descriptive way, using the Chi-square test of independence (ᵡ²) to evaluate associations. For analysis of variance, the study applied the ANOVA test followed by Tukey’s, with significance level at 5%. Results: Of the total of participants, 77.2% (n=129) had been diagnosed with mental disorders, and 22.8% (n=38) had not. Excess weight was observed in 73.1% (n=122) of those investigated, with a higher prevalence in the psychiatric population (89.4%, n=109). The mean BMI of the groups showed significant differences among schizophrenics (= 31.62 kg/m2; p<0.01), depressives (= 31.23 kg/m2; p=0.04), and those with other mood disorders (= 31.09 kg/m2; p=0.01) when compared to the group without mental disorders (= 25.51 kg/m2). Conclusion: It is evidenced the superiority of excess weight in the psychiatric population, especially in schizophrenics and depressives when compared to the population without mental disorders.
