Background: Anemia is more prevalent in low- and middle-income countries including India. Anemia in pregnancy is associated with increased risk of maternal health problems and adverse birth outcomes. This study estimates the prevalence and associated risk factors of anemia among pregnant women in India.
Methods: This cross-sectional study is based on secondary data from the India National Family Health Survey-V (NFHS-5) conducted during 2019-2021. We extracted data of 27,317 currently pregnant women to estimate the prevalence and contributory factors associated with anemia using descriptive statistics and logistic regression analysis.
Results: The prevalence of anemia among pregnant women in India was 52.2%. Anemia was higher among adolescent women (61.5%), those with no education (59.2%), those belonging to poorest wealth index (61.9%), scheduled tribes (59.3%), and those from the eastern region of India (62.1%). Further, it was more prevalent among women with a habit of smoking, tobacco, or alcohol (63.0%), and women with shorter birth intervals (59.7%). Among Indian states, anemia prevalence was higher in the state of Bihar (63.1%) and the union territory of Ladakh (71.4%). Logistic regression models show that women with no education (aOR = 1.41, 95% CI = 1.27-1.57), belonging to a poorest wealth quintile (aOR = 1.69, 95% CI = 1.51-1.90), and those with a habit of smoking, tobacco, or alcohol (aOR = 1.39, 95% CI = 1.18-1.63) were more anemic than their counterparts. Additionally, women with no education showed a four-times higher risk of severe anemia (aOR = 4.79, 95% CI = 2.75-8.36) than their highly educated counterparts.
Conclusion: Anemia affects half of all pregnant women in India. Anemia prevalence is higher among adolescents, illiterate, poor, and tribal communities. Social norm-based interventions and strengthening the community health facilitators should be implemented to reduce the high burden of anemia in India.

Anemia in pregnancy increases the risk of maternal and new-born health problems that lead to unfavorable pregnancy outcomes. This study aimed to find the current proportion and factors influencing anemia among currently pregnant Indian women. This study analyzed the data of 27,317 currently pregnant women reported with hemoglobin levels to find the prevalence and contributing factors of anemia. The study revealed that about 52.2% of pregnant women suffer from anemia inclusive of 1.4% with severe anemia. The anemia proportion was higher in women living in the eastern region of India, the poorest households, teenage pregnant women, and women with no formal education. Severity was higher in women belonging to the poorest households, tribal groups, and those with a habit of smoking, tobacco, or alcohol. Further, women with no formal education were four-times more likely to have a risk of severe anemia during their pregnancy. Maternal anemia hampers the growth and development of the newborns. Thereby, anemia adds a huge burden to the nation’s economy and health system. High rates of anemia among pregnant women could be a probable factor linked to the higher rate of maternal and child health illness and death in the eastern region, poorest strata, and other vulnerable populations in India. Special attention needs to be focused to ensure that these populations have easy access to healthy nutrition and the best public health systems.
