RESUMO
BACKGROUND: women who have inadequate nutrient intake are more likely to develop a risky pregnancy. The purpose of this study was to determine the presence of eating disorders and its association with anxiety and depression symptomatology in high-risk pregnancies. METHODS: this is a cross-sectional and prospective study conducted at the tertiary university hospital in the city of São Paulo, Brazil. 913 pregnant women waiting for the Obstetrics' outpatient appointment were invited to participate in the study on their 2nd and 3rd trimester of pregnancy. Structured interviews were carried out and the Structured Clinical Interview for DSM Disorders and Hospital Anxiety and Depression Scale were applied. FINDINGS: prevalence of eating disorder (ED) during pregnancy was 7.6% (n=69) (95% CI: 5.84% -9.28%), 0.1% (n=1) for anorexia nervosa; 0.7% (n=6) for bulimia nervosa; 1.1% (n=10) for binge eating disorder, and 5.7% (n=52) for pica. A statistically significant difference was found between the anxiety (p<0.01) and depressive symptoms (p<0.01). CONCLUSIONS: the prevalence of ED (7.6%) and its association with anxiety and depression symptoms during pregnancy highlights the need for specialist care for prevention, diagnosis and treatment. Given the importance of proper nutrition during pregnancy, both with regard to maternal health and fetal development, it is necessary to have specific predetermined evaluation protocols implemented by health care professionals for the diagnosis of ED during pregnancy.
