Son preference and health disparities in developing countries.

Area of Science:

• Global Health
• Gender Studies
• Development Economics

Background:

• Son preference is a persistent global issue, reflecting deep-seated gender inequality.
• This preference has historically influenced societal structures and resource allocation.
• Understanding its impact on child health is crucial for targeted interventions.

Purpose of the Study:

• To quantify the extent to which son preference affects health disparities between sons and daughters.
• To examine how these disparities manifest in anthropometric measures (height-for-age, weight-for-age).
• To identify vulnerable subgroups disproportionately affected by son preference.

Main Methods:

• Analysis of data from 66 developing countries.
• Comparison of height-for-age and weight-for-age z-scores between sons and daughters.
• Heterogeneity analysis to explore variations across socioeconomic and demographic factors.

Main Results:

• Daughters exhibit lower height-for-age and weight-for-age z-scores compared to sons, indicating poorer nutritional status.
• These anthropometric differences are statistically significant, linked to son preference.
• Disparities are more pronounced for children in rural areas, from lower-educated mothers, and poorer families.

Conclusions:

• Son preference demonstrably contributes to significant health inequalities between genders in developing nations.
• Children from disadvantaged backgrounds are particularly vulnerable to the negative health consequences of son preference.
• Addressing son preference is essential for improving global child health and achieving gender equity.
