Risks for preterm delivery and low birth weight are independently increased by severity of maternal anaemia

Objective. To estimate the effect of the severity of maternal anaemia on various perinatal outcomes. Design. A cross-sectional study. Setting. Labour Ward; Muhimbili National Hospital; Dar es Salaam; Tanzania. Methods. The haemoglobin of eligible pregnant women admitted for delivery between 15 November 2002 and 15 February 2003 was measu- red. Data on socio-demographic characteristics; iron supplementation; malaria prophylaxis; blood transfusion during current pregnancy; and current and previous pregnancy outcomes were collected and analysed. Anaemia was classified according to the World Health Organization (WHO) standards: normal - Hb =11.0 g/dl; mild - Hb 9.0 - 10.9 g/dl; moderate - Hb 7.0 - 8.9 g/dl; and severe - Hb 7.0 g/dl. Logistic regression analysis was performed to estimate the severity of anaemia. The following outcome measures were used: preterm delivery (37 weeks); Apgar score; stillbirth; early neonatal death; low birth weight (LBW) (2 500 g) and very low birth weight (VLBW) (1 500 g). Results. A total of 1 174 anaemic and 547 non-anaemic women were enrolled. Their median age was 24 years (range 14 - 46 years) and median parity was 2 (range 0 - 17). The prevalence of anaemia and severe anaemia was 68and 5.8; respectively. The risk of preterm delivery increased significantly with the severity of anaemia; with odds ratios of 1.4; 1.4 and 4.1 respectively for mild; moderate and severe anaemia. The corresponding risks for LBW and VLBW were 1.2 and 1.7; 3.8 and 1.5; and 1.9 and 4.2 respectively. Conclusion. The risks of preterm delivery and LBW increased in proportion to the severity of maternal anaemia

Anaemia in Pregnancy : a Major Health Problem with Implications for Material Health Care

Women (n=2235) registering for antenatal care in two maternal and child health clinics in the Dar es Salaam area between June; 1991 and June 1992 had their haemoglobin (Hb) measured by use of a HaemoCuer haemoglobinometer. The prevalence of anaemia Hb10.5 g/dl) was 60while severe anaemia (Hb7.0 //dl) was present in 4. Young nullparous women; those who register for antenatal care late in the third trimester; and undernourished women constitute high risk groups also for severe anemia and require special attention. No single maternal characteristics or combination thereof was useful to identify a group of screening. The current national Hb level for referral to hospital (8.5 g/dl) identified 20of the pregnant population. Most of these can successfully be treated and followed at the primary care level. To comply with the available means for care in the Dar es Salaam area; it is proposed that the cutoff level for referral be changed to 7g/dl. Appropriate methods to screen for anemia at primary health care (PHC) level must be explored and instituted. Training of antenatal care (ANC) providers in clinical identification of anemia and supply of haematinics must be improved and early booking for ANC promoted. Public health measures to improve the general nutrition and iron intake of all women are necessary to reduce this serious health problem in pregnancy
