Malaria ecology, child mortality & fertility

Area of Science:

• Demography
• Epidemiology
• Public Health

Background:

• Fertility determinants are broadly known, but quantitative drivers of fertility levels and changes require further understanding.
• The relationship between disease, child mortality, and fertility is complex and warrants deeper investigation.

Purpose of the Study:

• To investigate the effect of child mortality on fertility using a novel ecological index of malaria transmission.
• To quantify the impact of changes in child mortality on fertility rates.

Main Methods:

• Development and application of a novel ecological index for malaria transmission.
• Correlation analysis between malaria transmission, child mortality, and fertility rates.
• Estimation of the causal effect of child mortality changes on fertility.

Main Results:

• Temporal variations in malaria transmission ecology correlate strongly with mortality levels.
• Pernicious malaria conditions are associated with increased fertility rates.
• The majority of the effect of malaria on fertility operates through child mortality.

Conclusions:

• Child mortality is a significant mediator in the relationship between disease ecology and fertility.
• Evidence suggests that reductions in child mortality causally influence fertility changes.
• Findings contribute to the understanding of disease's impact on fertility dynamics.
