BackgroundMaternal depression in the pre- and postpartum period may set women on a course of chronic depressive symptoms. Little is known about predictors of persistently elevated depressive symptoms in mothers from pregnancy onwards. The aims of this study are to determine maternal depression trajectories from pregnancy to the child's fifth birthday and identify associated risk factors.MethodMothers (N = 1807) from the EDEN mother–child birth cohort study based in France (2003–2011) were followed from 24–28 weeks of pregnancy to their child's fifth birthday. Maternal depression trajectories were determined with a semi-parametric group-based modelling strategy. Sociodemographic, psychosocial and psychiatric predictors were explored for their association with trajectory class membership.ResultsFive trajectories of maternal symptoms of depression from pregnancy onwards were identified: no symptoms (60.2%); persistent intermediate-level depressive symptoms (25.2%); persistent high depressive symptoms (5.0%); high symptoms in pregnancy only (4.7%); high symptoms in the child's preschool period only (4.9%).Socio-demographic predictorsassociated with persistent depression were non-French origin;psychosocial predictorswere childhood adversities, life events during pregnancy and work overinvestment;psychiatric predictorswere previous mental health problems, psychological help, and high anxiety during pregnancy.ConclusionsPersistent depression in mothers of young children is associated to several risk factors present prior to or during pregnancy, notably anxiety. These characteristics precede depression trajectories and offer a possible entry point to enhance mother's mental health and reduce its burden on children.

Objective The objective was to determine the prevalence of iron deficiency and iron deficiency anemia among exclusively breastfed infants from one to six months of life and to identify associated risk factors. Methods This is a cohort study of the hemoglobin and serum ferritin levels of 102 healthy full-term infants, weighing more than 2500 grams (5.5 pounds) at birth, evaluated for growth development and supported to promote exclusive breastfeeding. Hemoglobin and ferritin levels were measured in the first, fourth, and sixth months of life. The hemoglobin and ferritin levels of the mothers were also measured in the first month postpartum. Results At four months, 5.7% presented iron deficiency and 3.4% had iron deficiency anemia. At six months, the percentage of children with iron deficiency increased more than four times, reaching 26.1%, while iron deficiency anemia was present in 23.9% of the infants studied. Iron deficiency at six months of age was significantly correlated to growth velocity. Conclusion According to the results of this study, exclusive breastfeeding protects infants from iron deficiency and iron deficiency anemia for the first four months of life. After this age, in accordance with the literature, the findings of this study demonstrated an increase in anemia and iron deficiency rates, adding to evidence that supports the monitoring of iron levels in exclusively breastfed children presenting higher weight gains beginning at four months of age.
