One of the government's initiatives to alleviate anemia afflicting adolescent Indonesian girls is iron and folic acid supplementation (IFAS).

Daily egg consumption was measured using 3-day 24-h dietary recalls.

The overall cognitive functioning test scores, separate scores for cognitive functioning subdomains, and the prevalence of cognitive impairment at the baseline were modestly higher among whole egg consumers than nonconsumers. However, after adjusting for individual characteristics, multivariate mixed-effects regressions did not find daily whole egg consumption to be associated with cognitive functioning among CHNS participants. By contrast, several demographic and socioeconomic factors, such as age, education attainment, and health insurance coverage, were found to correlate with older Chinese adults' cognition.ConclusionThis study has measurement and design limitations.
