This study was conducted to determine pregnant women's exposure to third-hand smoke, beliefs and influencing factors. The study included 400 pregnant women in a tertiary care obstetrics and gynecology hospital in Turkey. Data were collected using personal information form, Beliefs About Third-Hand Smoke Scale (BATHS-T) and Fagerström Test for…

Autism spectrum disorder is a developmental disorder that includes deficits in social communication and interaction, and restricted and repetitive behaviours, interests, or activities. This survey was done to assess autism spectrum disorder prevalence in 16- to 30-month-old children at an urban-rural distribution and determine the association of…

Every baby brings its own temperament with it into the world. Although it is widely accepted by scientists that genetic factors are effective in the formation of temperament, this study aims to examine the possible effects of the pregnancy process on the temperament characteristics of children in line with the experiences of mothers and the role…

Prenatal and postpartum depression are highly prevalent worldwide, and emerging evidence suggests they contribute to impairments in children's executive functions. Studies of maternal depression, however, have focused on the postpartum and postnatal periods with relatively less consideration of prenatal influences on child development. This study…

Prenatal folate and vitamin B[subscript 12] status have been linked to child neuropsychological development, but less is known about maternal genetic influences on this association. We conducted an exploratory longitudinal study of 181 mother--child pairs to assess whether maternal MTHFR 677C>T genotype modifies the association between maternal…

We estimated risk factors associated with suspected neuropsychomotor developmental delay at age 2 years, in a birth cohort in the Brazilian Amazon. The Maternal and Child Health and Nutrition in Acre (MINA-Brasil) study is a population-based birth cohort involving children born between July 2015 and June 2016 in the municipality of Cruzeiro do…

Genetics, environment, and their interactions impact autism spectrum disorder etiology. Smoking is a suspected autism spectrum disorder risk factor due to biological plausibility and high prevalence. Using two large epidemiological samples, we examined whether autism spectrum disorder was associated with prenatal paternal smoking in a Discovery…

The evidence for negative influences of maternal stress during pregnancy on child cognition remains inconclusive. This study tested the association between maternal prenatal stress and child intelligence in 4,251 mother-child dyads from a multiethnic population-based cohort in the Netherlands. A latent factor of prenatal stress was constructed,…

Identifying children at the risk of developmental delay can improve their long-term prognosis. In this case--control study, mothers and infants aged 6--18 months referred to healthcare centres affiliated with Qazvin University of Medical Sciences were recruited from August to December 2017. The sample size consisted of 197 individuals in…

Autism spectrum disorder (ASD) is a pervasive neurodevelopmental disorder that brings heavy burdens to families and the society. This case-control study explored risk factors for ASD based on 74,252 children aged 3-12 years who were recruited from general education kindergartens, primary schools, and special education schools in Shanghai, China.…

Emerging evidence suggests that prenatal stress does not solely undermine child functioning but increases developmental plasticity to both negative and positive postnatal experiences. Here we test this proposition using the Norwegian Mother and Child Cohort study while implementing an extreme-group (i.e., high vs. low prenatal stress) design (n =…

In order to examine (1) the stability of the mother-child-bond and (2) associations between mother-child-bonding and aspects of maternal-well-being, pregnant women (N = 170) completed measures on well-being and mother-child-bonding at two antepartum and two postpartum time points. We found relatively weak associations between mother-child-bonding…

Introduction: The appropriate role of evidence in health policy decision making is controversial and requires more data on how decisions are actually made. Option B+ is a strategy to prevent mother to child transmission (PMTCT) of HIV that involves starting pregnant, HIV-positive women on triple drug antiretroviral therapy (ART) and continuing for…

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder with poorly understood etiology. Many maternal exposures during pregnancy and breastfeeding potentially interfere with neurodevelopment. Using data from two age- and sex-matched case-control studies in Jamaica (n = 298 pairs), results of conditional logistic regression…

We investigated health-related quality of life in preterm children in association with birth weight, breastfeeding and maternal emotional state. A cross-sectional study was carried out involving 97 mothers of 2-year-old children born below 2500 g. Participants completed the Pediatric Quality of Life Inventory and a comprehensive psychological…
