[en] Introduction: Postpartum depression is a frequent health problem among women between 4 weeks and one year postpartum, with an incidence of between 10 and 13%. Physical exercise has been described as an alternative in the prevention of this mental disorder, but their relationship has not yet been fully established. Objective: To check if there is a relationship between the practice of grupal physical exercise during pregnancy and the risk of suffering postpartum depression. Methodology: This is a quantitative, quasi-experimental research with a design of control group and experimental group, through an intervention proposal with an unsupervised grupal program of physical exercise at the outdoor in pregnant women. In it, women from the health centers of Culleredo (A Coruña) will perform, before giving birth, a moderate-intensity 30-minute walks, 5 days a week for 12 weeks through the Paseo del Burgo. With this intervention, and secondarily to this project, we try to promote health, in this case through physical exercise, to obtain both maternal and fetal health benefits, by reducing the risk of suffering postpartum depression. This association will be studied by analyzing the level of physical exercise of pregnant women, using an accelerometer, in weeks 24-26 and 32-34 of pregnancy. This information will triangulate with data from the clinical history, with a prenatal (in the first consultation) and postnatal (within 40 days postpartum) personal interview and with the results of the EPDS scale, managed in two moments: at 24 weeks of gestation and at 3 months postpartum.

[gl] Introducción: A depresión postparto é un problema de saúde frecuente nas mulleres entre as 4 semanas e o ano postparto, cunha incidencia de entre o 10 e o 13%. Describiuse o exercicio físico coma unha alternativa na prevención de dito trastorno mental, pero a súa relación todavía non se constatou na súa totalidade. Obxectivo: Comprobar se existe relación entre a práctica de exercicio físico en grupo durante o embarazo e o risco de sufrir depresión postparto. Metodoloxía: Tratase dunha investigación cuantitativa, cuasi experimental cun deseño de grupo control e grupo experimental, mediante unha proposta de intervención cun programa grupal non supervisado de exercicio físico ao aire libre en mulleres embarazadas. Nel, as mulleres dos centros de saúde de Culleredo (A Coruña) realizarán andainas, previas ao parto, de 30 minutos e cunha intensidade moderada, 5 días á semana durante 12 semanas polo paseo do Burgo. Con dita intervención, e de forma secundaria a este proxecto, buscase promover a saúde, neste caso mediante o exercicio físico, para obter beneficios tanto maternos e fetales como sanitarios, ao disminuir o risco de sufrir depresión postparto. A relación pesentada no obxectivo estudiase mediante o análise do nivel de actividade física das embarazada, utilizando un acelerómetro, nas semanas 24-26 e 32-34 de xestación. Este dato triangulará con datos da historia clínica, da entrevista personal prenatal (na primera consulta de seguimento) e postnatal (dentro dos 40 días postparto) e cos resultados da escala EPDS, administrada en dous momentos: ás 24 semanas de xestación e aos 3 meses postparto.
