"The aim of this paper is to analyze empirically the causal relationship, if any, between infant mortality and fertility in thirty-five developing countries." The focus is on possible relationships between the infant mortality rate and the fertility rate. "The hypothesis that infant mortality causes fertility is tested. The possibility of a 'reverse causation' is also analyzed. A one-sided ...

Different family compositions and sizes may affect child development through the different modes of interaction between family members. Previous studies have compared only children with non-only children in cognitive/non-cognitive outcomes. However, relatively little research has systematically investigated the potential moderators among them. Using a large and representative sample of Chinese ...

The data comprised of sociodemographic and other obstetric data, which were cleaned, recoded, and analyzed using STATA version 13 (Stata Corporation, College Station, TX, USA).

'Demographic transition theory' assumes that fertility decline is irreversible. This commonly held assumption is based on observations of recent and historical reductions in fertility that accompany modernization and declining mortality. The irreversibility assumption, however, is highly suspect from an evolutionary point of view, because demographic traits are at least partially influenced by ...

Community case management (CCM) is a strategy for training and supporting workers at the community level to provide treatment for the three major childhood diseases--diarrhea, fever (indicative of malaria), and pneumonia--as a complement to facility-based care. Many low- and middle-income countries are now implementing CCM and need to evaluate whether adoption of the strategy is associated with...

Assessments of undernutrition are typically based on comparisons between anthropometric indicators of children and a reference standard from the US. Due to a number of problems associated with this reference standard, WHO is currently engaged in generating a new international reference standard for child growth based on well-to-do populations in a sample of poor and rich countries. The focus on...

Injectable contraceptives are fast becoming the method of choice among married women in sub-Saharan Africa. In several countries in the region, the proportion of women using injectable methods has surpassed the proportion of women using the pill. This is true even in some countries where the pill had been the most popular modern method in the 1980s and 1990s. This paper analyzes data from six s...
