Sex differences in mortality among young children in the Sahel.

"This article studied sex differences in mortality among children aged 1-23 months in the cities of Bamako [Mali] and Bobo-Dioulasso [Burkina Faso] and in a rural area of Senegal. No significant differences between male and female mortality risks were found in any of the areas for the full age span of 1-23 months. For smaller age groups, patterns of excess female and male child mortality are evident. Excess female mortality, statistically significant in standard tests, exists among children aged 1-8 months in the Senegalese area and 6-15 months in the combined urban areas of Bamako and Bobo-Dioulasso. Excess male mortality occurs for ages 16-23 months in the city of Bamako."
