Previous research reports mixed results about the association between maternal height and child mortality. Some studies suggest that the negative association might be stronger in contexts with fewer resources. This hypothesis has yet not been tested in a cross-nationally comparative design. We use data on 307,223 children born to 194,835 women in 444 districts of 42 developing countries to esti...

Thyroid hormones are essential for brain development, and maternal thyroid disease may affect child neurocognitive development. Some types of seizures may also depend upon early exposure of the developing central nervous system, and we hypothesized that maternal thyroid dysfunction could increase the risk of seizure in the child. In a Danish population-based study we included 1,699,693 liveborn...

IMPORTANCE Few studies have examined the curtailment of reproduction (ie, stoppage) after the diagnosis of a child with autism spectrum disorder (ASD).

DESIGN, SETTING, AND PARTICIPANTS Individuals with ASD born from January 1, 1990, through December 31, 2003, were...

BACKGROUND The occurrence of multiple births has been recognized as a risk factor for child maltreatment. However, few population-based studies have examined the relationship between multiple births and child maltreatment. This study aimed to evaluate the degree of risk of child maltreatment among singletons and multiple births in Japan and to identify factors associated with increased risk. ...

The relationship between poverty and nutrition is a two-sided one: on the one hand, economic growth (which is generally associated with an eradication of poverty) leads to reduced malnutrition. On the other hand, nutrition is one of the key ingredients for human capital formation, which in turn represents one of the fundamental factors of growth. There are numerous studies that show the correla...

vs. 61%). Whether or not a woman conceived a child did not affect the mean religiosity of the sample Women who had a child during cohabitation had lower education levels than the entire sample—almost half (46%) had less than 12 years of education, while a quarter of the total sample had not completed 12 years.
