In this population-based sample, we found associations between GAD, PTSD, and increased prevalence of illicit substance abuse/dependence. In addition, individuals with agoraphobia seem to have increased tobacco abuse/dependence.

The results showed that only the perception of maternal bonding was associated with later GAD. It suggests that an adequate maternal bond is an essential component of psychological health.

Highlights Brief CBT in pregnancy was effective in preventing PPD. CBT improved interpersonal relationships and understanding of social status (OQ-45). Education, among the risk factors for PPD, was decisive in the effectiveness of CBT.

To evaluate the relationship between maternal cognitive performance and language and cognitive development of children between 24 and 36 months old of mothers who became pregnant in adolescence, in the city of Pelotas, Southern Brazil. This is a cross-sectional study nested in a cohort study with adolescent mothers who received prenatal care in the city’s public health system. To assess maternal cognitive performance, the Montreal Cognitive Assessment (MoCA) was used and Bayley Scales of Infant Development III (BSID-III) are used to assess children's language and cognition development. Data were analyzed using SPSS (Version 22.0) software. Pearson correlation, t-test, ANOVA and linear regression were performed. We evaluated 496 mother-child dyads. In the adjusted analysis, we found that children's language remained associated with maternal cognitive performance (p = .027, CI [0.0, 0.6]) and child’s gender (p < .001, CI [−7.2, −2.4]). Besides that children cognitive development remained associated with maternal cognitive performance (p = .008, CI [0.1, 0.6]) and child’s gender (p = .030, CI [−4.5, −0.2]). Our results suggest that poor maternal cognitive performance is associated with lower levels of children's language and cognitive development. The results contributing to early identification and intervention in children of mothers with poor cognitive performance at higher risk of negative developmental outcomes.

The COVID-19 pandemic has changed individuals and families, causing adverse psychological effects, especially in young adults, women, and parents. This study aimed to verify the prevalence of current major depressive episode (CMDE) in mothers of preschoolers (up to five years old) and its associated stressors during the COVID-19 pandemic in a municipality in the Southern Brazil. This is a cross-sectional, population-based study with mothers. All mothers were interviewed by telephone call during the COVID-19 pandemic. We used the Mini-International Neuropsychiatric Interview (M.I.N.I. Plus) to assess the presence of CMDE. Statistical analysis was conducted using the chi-square test and a multivariate logistic regression. We evaluated 666 mothers. The prevalence of CMDE was 12.3%. Mothers with financial losses had 2.1 (95%CI: 1.3-3.4) more odds of presenting CMDE than those financially stable. We observed that financial losses were determinant for the higher prevalence of depression in mothers.
