Country development and the association between parity and overweight

Area of Science:

• Global Health
• Epidemiology
• Reproductive Health

Background:

• Parity is linked to overweight in developed nations and maternal depletion in developing ones.
• Existing research from developing countries may not reflect current development stages.
• The relationship between parity and overweight needs further investigation in diverse economic contexts.

Purpose of the Study:

• To examine the association between parity and overweight across countries with varying wealth and development levels.
• To understand how national economic status influences the parity-overweight relationship.

Main Methods:

• Analysis of data from 50 Demographic and Reproductive Health Surveys (1992-2003).
• Parity was assessed by the number of live births.
• Overweight was defined as a body mass index (BMI) >= 25 kg/m(2).

Main Results:

• Women with at least four live births had higher odds of being overweight in 38 out of 50 countries.
• The median odds ratio for overweight was consistently above 1.0 across all studied regions.
• North Africa and West Asia showed the highest odds ratios, with all countries exhibiting this trend.
• Higher country wealth and development levels were positively associated with increased odds ratios for overweight.

Conclusions:

• The predictive power of parity for overweight status escalates with national economic development and wealth.
• Public health policies should consider interventions for excessive gestational weight gain and postpartum weight loss.
• Promoting dietary changes, physical activity, and exclusive breastfeeding are recommended strategies.
