Characterization of 843 children with Zika-related microcephaly in the first three years of life: An individual participant data meta-analysis of 12 cohorts in the Zika Brazilian Cohorts consortium
One of the main gaps in characterizing the congenital Zika syndrome (CZS) up to now is the small number of participants in individual studies. Pooling the data together overcomes the sample size-related limitations of individual studies and provides an opportunity for investigating heterogeneity between studies and, as appropriate, to better characterize the CZS . This study aims to describe adverse anthropometric, clinical, and neuroimaging outc…
Course of depression during the first 2 years postpartum among Brazilian women enrolled in a conditional cash transfer program
BACKGROUND: Women living in low- and middle-income countries are more exposed to known risk factors for depression occurrence and persistency over time. AIM: Our aim was to investigate the course of depression in the first 2 years postpartum among Brazilian women enrolled in a cash transfer program. METHOD: Longitudinal analysis of baseline (T0; mean 3.7 months postpartum) and first follow-up data (T1; mean 18.6 months postpartum) from a trial to…
Asthmatic Symptoms in Children and Adolescents: The Role of Maternal Experiences of Racial Discrimination
Emerging evidence suggests that vicarious racial experiences of discrimination may negatively influence child health. Few studies have focus on childhood asthma symptoms and potential moderators of such relationship. METHODS: We used two population-based cross-sectional studies from the Social Change Allergy and Asthma in Latin America project in Salvador, Brazil. A total of 1003 children and mothers interviewed in 2006 were included, of whom 873…

The Salvador Primary Care Longitudinal Study of Child Development (CohortDICa) Following the Zika Epidemic: Study Protocol
This article describes the Salvador Primary Care Longitudinal Study of Child Development (CohortDICa). The exposed group was defined by confirmation of Congenital Zika Syndrome (CZS) diagnosed through computed tomography, magnetic resonance or transfontanellar ultrasound. A random selection of the 169 exposed children led to a subgroup of 120 children who were paired with children from the Live Birth Information System, according to birthdate, re…

Experiences of Discrimination and Skin Color Among Women in Urban Brazil: A Latent Class Analysis
Experiences of discrimination are an important aspect of women's life in Brazil, especially Black women. The Experiences of Discrimination scale (EOD) is often used for assessing discrimination in epidemiological studies, although divergent cutoff points have been used to characterize the exposure. We used latent class analysis (LCA) and logistic regression to identify and characterize subgroups of women exposed to discrimination and compared wit…

Measuring the level of social support using latent class analysis
Different instruments have been used to measure social support in epidemiological studies of which the most widely used is the Medical Outcomes Study Social Support Scale (SSS-MOS). However, these studies lack measures of the level of social support on health risks. We used latent class analysis (LCA) to distinguish subgroups with different levels of perceived social support and tested the consistency of these subgroups by their associations with…
Maternal mental health and social support: Effect on childhood atopic and non-atopic asthma symptoms
BACKGROUND: Atopic and non-atopic asthma have distinct risk factors and immunological mechanisms, and few studies differentiate between the impacts of psychosocial factors on the prevalence of these disease phenotypes. The authors aimed to identify whether the effect of maternal mental health on prevalence of asthma symptoms differs between atopic and non-atopic children, taking into account family social support. METHODS: This is a cross-section…
P2-374 Behaviour problems and overweight adolescents: The role of gender and resilience
It is well-recognised that obesity is a complex, multifactorial condition which includes both genetic and environmental factors. Although it is controversial, there is evidence that behavioural problems and being overweight are associated. Furthermore, relatively few studies have analysed the role of resilience in this relationship. Objective To analyse the association between behaviour problems (BP) and the overweight condition (OW) among adoles…
SP1-40 Maternal mental health and social support: Effects on atopic and non-atopic asthma in children
Introduction Although there is evidence that atopic and non-atopic asthma have distinct risk factors and immunological mechanisms, there are few studies that consider the effect of psychosocial factors on these asthma phenotypes. We aimed to identify if the effects of common maternal mental health disorders and the presence of family social support on asthma occurrence in children. Methods A cross-sectional study including 1042 children from an i…
Structural equation modeling in epidemiology
Structural equation modeling (SEM) is an important statistical tool for evaluating complex relations in several research areas. In epidemiology, the use and discussion of SEM have been limited thus far. This article presents basic principles and concepts in SEM, including an application using epidemiological data analysis from a study on the determinants of cognitive development in young children, considering constructs related to organization of…
Determinants of cognitive function in childhood: A cohort study in a middle income context
Children's cognitive development in urban contexts in developing countries could be substantially increased by interventions promoting early psychosocial stimulation and preschool experience, together with efforts to prevent low birth weight and promote adequate nutritional status
Determinants of early cognitive development: Hierarchical Analysis of a Longitudinal Study
The study describes the relationship between anthropometric status, socioeconomic conditions, and quality of home environment and child cognitive development in 320 children from 20 to 42 months of age, randomly selected from 20,000 households that represent the range of socioeconomic and environmental conditions in Salvador, Bahia, Northeast Brazil. The inclusion criterion was to be less than 42 months of age between January and July 1999. Child…
