P156 – 1637 Breastfeeding may protect from developing attention deficit and hyperactivity disorder

BackgroundBreastfeeding is negatively associate with behavioral and internalization problems, psychological stress, and depressive/anxiety symptoms. However, studies evaluating specific mental health disorders are scarce. We aimed to assess the association between breastfeeding and mental health outcomes in young adults.MethodsIn 1982, hospital deliveries in Pelotas (Southern Brazil) were identified; liveborns were examined and their mothers interviewed (n=5914). Information on breastfeeding was collected in early childhood. In 2012–13, at 30 years of age, we used the Mini International Neuropsychiatric Interview (MINI) for the diagnosis of major depression (MD), generalized anxiety disorder (GAD) and social anxiety disorder (SAD). In addition, we used the Beck Depression Inventory (BDI-II) and the Self-reported Questionnaire (SRQ-20), to evaluate depressive symptoms severity and common mental disorders (CMD), respectively. We used multivariable regression models to evaluate the association between breastfeeding and mental health outcomes.ResultsWe evaluated 3657 individuals. Prevalence of CMD, MD, GAD and SAD was 24.3%, 7.9%, 12.7% and 3.6%, respectively. In multivariable models the odds of having a more severe case of depression (BDI-II) was smaller among those breastfed for 6 or more months (OR=0.69 95%CI [0.53–0.89]). We observed a similar pattern for MD and CMD, however, confidence intervals included the reference.LimitationsWe had no information on home environment characteristics during childhood. Lack of power and a small effect size could explain why we did not detect an association between breastfeeding and MD.ConclusionBreastfeeding reduced the odds of having more severe depressive symptoms.

Resumo: O objetivo foi avaliar o efeito da exposição e do tempo de exposição ao aleitamento materno na ocorrência de transtornos mentais comuns (TMC) entre adolescentes escolares brasileiros. Este trabalho analisou dados do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA), avaliando aqueles que tiveram o questionário referente ao aleitamento materno respondido pelos pais ou responsáveis. A presença de TMC foi identificada pelo General Health Questionnaire, versão 12 itens (GHQ-12), considerando-se dois pontos de corte (escores ≥ 3 e ≥ 5). As associações foram testadas em análises bivariadas e por meio de modelos de regressão logística múltipla, com ajustes por variáveis potenciais de confusão. Dentre os 41.723 adolescentes avaliados, a maioria foi composta por estudantes do sexo feminino (54,6%), que tinham idades entre 12 e 15 anos (71%), estudavam em escolas públicas (83,1%), residiam na Região Sudeste (51,9%) e eram das classes econômicas B (53,8%) e C (34,1%). Cerca de metade das mães dos adolescentes não tinha o ensino médio completo (51,7%). O grupo de adolescentes com mais de seis meses de aleitamento materno (51,8%) apresentou uma menor prevalência de TMC para os dois pontos de corte do GHQ-12 avaliados, quando comparado com o grupo que não recebeu aleitamento materno ou que o recebeu por período ≤ 1 mês (RI = 0,82; IC95%:0,69-0,97 e RI = 0,74; IC95%: 0,59-0,91 para 3 e 5 pontos, respectivamente). O aleitamento materno prolongado parece desempenhar um papel protetor para a ocorrência de TMC na adolescência.
