Are adolescents more likely to have antenatal anxiety disorders than adult women? A comparison between two samples.

BACKGROUND: The literature reports that teenage pregnancy is considered a risk factor for anxiety disorders (ADs). However, research on this topic is limited. This study aimed to investigate if pregnant adolescents presented a greater likelihood of having ADs by comparing two samples of pregnant women in a southern city of Brazil. We also observed the prevalence rates of antenatal ADs among adolescents and adult women. METHODS: In this cross-sectional study, we evaluated 1852 women from two different studies: 995 pregnant adolescents attending prenatal care in the public health system (convenience sample) and 857 pregnant women from a population-based study. We used the Mini International Neuropsychiatric Interview (MINI Plus) to assess antenatal ADs, using the Social Anxiety Disorder (SAD) and Generalized Anxiety Disorder (GAD) modules. The primary aim of this study was tested through multivariate analysis using Poisson regression. RESULTS: The prevalence of ADs was 11.0 % among pregnant adolescents and 13.8 % among adult pregnant women. Both samples presented similar rates of ADs (p = 0.065). In the adjusted analysis, maternal age did not predict antenatal ADs (PR = 0.97; p = 0.853). LIMITATIONS: Considering the particularities of each study where the samples came from, it was not possible to include other ADs such as panic disorder or phobias. CONCLUSIONS: Our findings suggest that pregnancy in adolescence does not increase the likelihood of antenatal ADs. However, we emphasize the importance of an adequate psychological screening and care in pregnancy in order to prevent possible psychiatric disorders.

Cognitive and language performance in children is associated with maternal social anxiety disorder: A study of young mothers in southern Brazil.

BACKGROUND: It has been shown that maternal mental health is associated with poorer skills development in the offspring. However, the evidence evaluating the association between social anxiety disorder (SAD) and cognitive or language development, is scarce. AIM: To evaluate the association between maternal SAD and performance in cognitive and language tests in 30-month old children. STUDY DESIGN: This was a cohort study involving young women evaluated since pregnancy. SUBJECTS: We evaluated 520 mother-child dyads who received prenatal medical assistance through the National Public Health System in a southern Brazilian city, from October 2009 to March 2011. OUTCOME MEASURES: We used the Mini Neuropsychiatric Interview Plus (MINI Plus) to assess SAD among young mothers. Cognitive and language performance in their offspring was analyzed using the Bayley Scales of Infant and Toddler Development - 3rd Edition. RESULTS: We found an association between maternal SAD and performance in cognitive and language tests. Children of mothers with SAD had in average 4.5 less points in the Bayley scale, when compared to those with mothers without SAD: in the cognitive (ß=-4.53 [95% CI -7.8; -1.1] p=0.008) and language subscales (ß=-4.54 [95% CI -9.0; -0.5] p=0.047). CONCLUSIONS: Our findings suggest that children with mothers suffering from SAD have poorer cognitive abilities and language skills.
