Mortality among Serere children in Senegal

Area of Science:

• Child Health
• Nutritional Epidemiology
• Demography

Background:

• Seasonal variations in nutrition affect child survival in resource-limited settings.
• Understanding child mortality risk factors is crucial for public health interventions.

Purpose of the Study:

• To investigate the relationship between seasonal nutritional status and child survival in rural Senegal.
• To identify key risk factors, including Body Mass Index (BMI), birth rank, and maternal age, associated with child mortality.

Main Methods:

• Utilized hazard models to analyze risk factors for child mortality in a sample of 40 Serere households.
• Incorporated sequentially observed data to assess the impact of changing nutritional status (BMI) over time.

Main Results:

• Child nutritional status, reflected by BMI, emerged as the most significant risk factor for mortality.
• A declining relative BMI was strongly associated with a sharply increasing hazard rate for child mortality.
• Birth rank and maternal age were also linked to child survival, particularly when combined with poor nutritional status.

Conclusions:

• Nutritional status is a critical determinant of child survival in this Senegalese rural population.
• Dynamic changes in BMI significantly influence child mortality risk.
• Interventions addressing nutritional status, alongside considerations for birth rank and maternal age, are vital for improving child survival.
