A randomized trial to assess the effectiveness of an infant home safety programme

The aim of this study was to test an intervention aimed at addressing the risk of injury in infants 2 - 12 months of age. A non-blinded, randomized controlled trial was conducted, whereby parents were randomly assigned to either a control or one of two intervention groups. Parents completed questionnaires regarding safety behaviours and injuries at the 2 (baseline), 6 and 12 month immunization visit at the community health unit. During the 2 month visit to the health unit, the two intervention groups received a home safety kit containing nine items, an instructional brochure and a risk assessment checklist. Subjects randomized to the safety kit plus home visit group also received a standardized home visit from a community health nurse. Two of the 14 parental safety behaviours showed a significant increase in use among parents in the intervention groups. Neither of the interventions was associated with a reduction in parent-reported injuries among children. It was concluded that home visitation may provide a beneficial adjunct to the provision of safety devices and may increase use by parents.

Why do mothers breastfeed girls less than boys? Evidence and implications for child health in India

Breastfeeding is negatively correlated with future fertility because nursing temporarily reduces fecundity and because mothers usually wean on becoming pregnant again. We model breastfeeding under son-biased fertility preferences and show that breastfeeding duration increases with birth order, especially near target family size; is lowest for daughters and children without older brothers because their parents try again for a son; and exhibits the largest gender gap near target family size, when gender is most predictive of subsequent fertility. Data from India confirm each prediction. Moreover, child survival exhibits similar patterns, especially in settings where the alternatives to breastmilk are unsanitary.     

Modernization, weather variability, and vulnerability to famine

This paper shows that under weather variability the transformation from a rural to an incomplete market economy can increase the vulnerability of peasants to famine. This can occur even if improvements in technology have raised agricultural productivity and made production less responsive to weather variability. Indeed, negative environmental shocks can produce a drop in wages that outweighs the increase in wages due to an equivalent positive environmental shock. Consequently, the amount of grain stored increases more slowly in good seasons than it decreases in bad ones. This paper gives new insights on the catastrophic effects produced by widespread droughts in India during the second half of the 19th century. Notwithstanding the introduction of new modes of production and the modernization of infrastructures, the interaction between environmental variability and new institutional arrangements might have contributed to increase the vulnerability of peasants to famine.
