Management of Iron Deficiency Anemia in Pregnancy in India.

ABSTRACT: Iron deficiency anemia (IDA) continues to be the commonest etiology of anemia in pregnancy. The prevalence of iron deficiency (ID) in pregnant Indian women is amongst the highest in the world. Untreated iron deficiency (ID) has significant adverse feto-maternal consequences. Plethora of investigations are available for diagnosis of IDA, each having specific advantages and disadvantages when used in the pregnancy setting. Therapy for ID includes dietary modification, oral iron supplementation, intravenous iron and blood transfusion. Newer parenteral iron preparations are safe and there is mounting evidence to suggest their use in frontline settings for pregnancy associated IDA in the second and third trimester. Through this review, we suggest an algorithm for diagnosis and treatment of IDA in pregnancy depending on the severity of anemia and period of gestation suited for widespread use in resource limited settings. Also, we recommend ways for increasing public awareness and tackling this health issue including the observance of "National Anemia Awareness and Treatment Day."

Project description:Background:The effect of maternal weights on the risk of iron deficiency anemia (IDA) during pregnancy remains unclear. The study aimed to investigate the association between maternal weight indicators and IDA during pregnancy. Methods:We conducted a cohort study to examine the association between maternal weight indicators, including prepregnancy body mass index and the rate of gestational weight gain (GWG), and the risk of IDA among Chinese pregnant women. Data about new-onset IDA at different trimesters from a national cross-sectional survey were collected; information regarding baseline variables and rate of GWG from women participating in the survey were retrospectively collected. Tested IDA and reported IDA were documented. Multilevel logistic regression to examine the association between maternal weight indicators and the risk of IDA after adjusting for potential confounders was conducted. Results:This study enrolled 11,782 pregnant women from 24 hospitals from September 19, 2016, to November 20, 2016. Among those, 1515 (12.9%) IDA events were diagnosed through test (test IDA); 3915 (33.3%) were identified through test and patient reporting (composite IDA). After adjusting for confounders and cluster effect of hospitals, underweight pregnant women, compared with normal women, were associated with higher risk of test IDA (adjusted odds ratio [aOR]: 1.35, 95% confidence interval [CI]: 1.17-1.57 and composite IDA (aOR: 1.35, 95% CI: 1.21-1.51); on the contrary, overweight and obese women had lower risk of test IDA (aOR: 0.68, 95% CI: 0.54-0.86 overweight; aOR: 0.30, 95% CI: 0.13-0.69 obese) and composite IDA (aOR: 0.77, 95% CI: 0.67-0.90 overweight; aOR: 0.34, 95% CI: 0.21-0.55 obese). The higher rate of GWG was associated with higher risk of IDA (test aOR: 1.86 95% CI: 1.26-2.76; composite aOR: 1.54, 95% CI: 1.16-2.03). Conclusions:Pregnant women who are underweight before pregnancy and who have faster GWG are more likely to develop IDA. Enforced weight control during pregnancy and use of iron supplements, particularly among underweight women, may be warranted.

Project description:Background/objectivesWe examined the prevalence of anaemia, iron deficiency, and inflammation during pregnancy and their associations with adverse pregnancy and infant outcomes in India.Subjects/methodsThree hundred and sixty-six women participating in a randomised trial of vitamin B12 supplementation were monitored to assess haemoglobin (Hb), serum ferritin (SF), hepcidin, C-reactive protein (CRP), and alpha-1-acid glycoprotein (AGP) during pregnancy. Women received vitamin B12 supplementation (50 µg per day) or placebo daily; all women received daily prenatal iron-folic acid supplementation. Binomial and linear regression models were used to examine the associations of maternal iron biomarkers with pregnancy and infant outcomes.ResultsThirty percent of women were anaemic (Hb < 11.0 g/dl), 48% were iron deficient (SF < 15.0 µg/l), and 23% had iron deficiency anaemia at their first prenatal visit. The prevalence of inflammation (CRP > 5.0 mg/l: 17%; AGP > 1.0 g/l: 11%) and anaemia of inflammation (Hb < 11.0 g/dl, SF > 15.0 µg/l, plus CRP > 5.0 mg/l or AGP > 1.0 g/l: 2%) were low. Infants born to anaemic women had a twofold higher risk of low birth weight (<2500 g; risk ratio [RR]: 2.15, 95%CI: 1.20-3.84, p = 0.01), preterm delivery (RR: 2.67 (1.43-5.00); p = 0.002), underweight (WAZ < -2; RR: 2.20, 95%CI: 1.16-4.15, p = 0.02), and lower MUAC (β(SE): -0.94 (0.45)cm, p = 0.03). Similarly, maternal Hb concentrations predicted higher infant birth weight (p = 0.02) and greater gestational age at delivery (β(SE): 0.28 (0.08) weeks, p = 0.001), lower risk of preterm delivery (<37 weeks; RR: 0.76, 95%CI: 0.66-86, p < 0.0001); and higher infant MUAC (β(SE): 0.36 (0.13) cm, p = 0.006). Maternal SF concentrations were associated with greater birth length (β(SE): 0.44 (0.20) cm, p < 0.03). Findings were similar after adjusting SF concentrations for inflammation. IDA was associated with higher risk of low birth weight (RR: 1.99 (1.08-3.68); p = 0.03) and preterm birth (RR: 3.46 (1.81-6.61); p = 0.0002); and lower birth weight (p = 0.02), gestational age at birth (p = 0.0002), and infant WAZ scores (p = 0.02).ConclusionsThe prevalence of anaemia and iron deficiency was high early in pregnancy and associated with increased risk of adverse pregnancy and infant outcomes. A comprehensive approach to prevent anaemia is needed in women of reproductive age, to enhance haematological status and improve maternal and child health outcomes.
