Background and objectives: Despite enduring efforts in Indonesia to eliminate anemia in pregnancy, it remains a major nutritional problem. Its nutritional contributors were reevaluated.
Methods: A meta-analysis of reports on anemia during pregnancy in Indonesia from January 2001 to December 2019 in the PubMed and ProQuest databases was conducted. Pooled ORs were obtained in fixed- and random-effects models. Funnel plots and Egger's and Begg's tests were used to evaluate publication bias. Review Manager 5.3 and Stata version 14.2 were used for analysis.
Results: A total of 2,474 articles were appraised. Systematic review and meta-analysis were performed on 10 studies including 4,077 participants. Chronic energy deficiency had the highest OR for the risk of anemia (3.81 [95% CI: 2.36-6.14]) followed by greater parity (OR=2.66 [95% CI: 1.20-5.89]), low education level (OR=2.56 [95% CI: 1.04-6.28]), and limited health knowledge (OR=1.70 [95% CI: 1.17-2.49]), whereas older age and inadequate iron supplementation were not apparently associated with maternal anemia (p > 0.05).
Conclusion: Future policies and strategic action to reduce nutritional anemia during pregnancy in Indonesia should increase emphasis on local nutritional epidemiology to establish the pathogenesis of anemia and the validity of stand-alone single-nutrient interventions. Attention to chronic energy deficiency as a barrier to preventing anemia in pregnancy may be necessary to enable health workers and women at risk to be better informed in their efforts.
