Introduction: Surveys in different parts of India indicate that about 50 to 60 per cent of women belonging to low socio-economic groups are anemic in the last trimester of pregnancy. The major etiological factors are iron and folic acid deficiencies. Materials and Methods: In current study baseline data of antenatal cases is recorded with the help of a pre-tested questionnaire. Their blood samples are collected on the date of registration and analyzed for hemoglobin concentration by cyan meth hemoglobin method. First pack of IFA containing 30 tablets is given to the subjects along with administration instructions. These steps were repeated on subsequent antenatal visits at 20, 32 and 36 weeks of pregnancy as per norms. During these subsequent visits hemoglobin concentrations are measured and compliance for IFA supplementation is enquired. Results: A total of 598 subjects could be followed till the outcome of pregnancy. The mean age was 23.6 yrs. Out of all the risk factors complicating pregnancy most common risk factor was anemia. Most common type of anaemia was due to iron deficiency. Mean Hemoglobin values at the time of registration did not vary significantly in respect to their age groups, community, economic status, gravid status and parity of pregnancy. Conclusion: Mean Hemoglobin values varied significantly with the literacy status of women. Mean Hemoglobin values varied significantly at every visit with supplementation of IFA. All the women receiving IFA supplementation did not have adequate hemoglobin levels at the time of delivery.

Introduction

Anaemia remains a major public health problem, affecting about a quarter of the world's population [1]. Its adverse health consequences affect people with varied degrees of affluence and from all age groups, particularly women of childbearing age and children [2]. A WHO expert group proposed that anemia should be considered to exist when hemoglobin is below 11 g/dl of venous blood in adult female pregnant [3]. WHO has estimated that prevalence of anaemia in pregnant women is 65-75 per cent in India [4].

India contributes to about 50% of global maternal deaths due to anaemia [5]. Data from NNMB, ICMR and DLHS surveys have shown that prevalence of anaemia is very high (ranging between 80->90%) in pregnant and lactating women and adolescent girls [6-8]. Pregnant women with Haemoglobin less than 8 g/dl show functional decompensation and constitute a high risk group [9]. Haemoglobin levels of 11 g/dl in the late first trimester and also of 10 g/dl in the second and third trimesters are suggested as lower limits for Haemoglobin concentration [10].

The major aetiological factors being iron and folic acid deficiencies. About two billion people are iron deficient, with half of them manifesting clinical signs of anaemia [11]. It is estimated that 75% of anaemia is related to iron deficiency, followed by folate and vitamin B12 deficiencies [12-14]. Anemia per se is associated with high incidence of premature births, post partum hemorrhage, puerperal sepsis and thromboembolic phenomenon in the mother. The micronutrient status of high-risk populations has recently received extensive attention as it adversely affects pregnancy outcome, working ability, intellectual capacity, and immunity, including enormous economic drainage [15,16].

Because of the persistently high burden of disease, the World Health Organization has long recommended the prenatal use of iron supplements in low and middle income countries, and this is also recommended in many high income countries [17-19]. The Government of India has initiated a program in which 100 mg of elemental Iron and 500 mcg of folic acid are being distributed daily to pregnant women through antenatal clinics, primary health centers and their sub centers.

Current study is carried in the field practice area of a Rural Health Center, Chennur, Kadapa.

Study subjects are pregnant women registered in the Rural Health center. Auxiliary Nurse and Midwifes (ANMs) at these centers carry out registration of pregnant women with the help of Anganwadi staff and Accredited Social Health Activist (ASHA) workers in their respective sub centers. A minimum of four antenatal visits are paid by the ANM and distribute iron folic acid tablets to these pregnant women. The aim of the study is to know the effect of Iron Folic Acid Supplementation on the Haemoglobin concentration of Antenatal Cases.

Materials and Methods

By assessing the hemoglobin levels of the pregnant women at the time of registration and at subsequent antenatal visits after supplying Iron and Folic Acid (IFA) tablets and at 1 week before Expected Date of Delivery (EDD) the effectiveness of IFA supplementation can be assessed. Also by following the pregnant women till the outcome of pregnancy the usefulness and the requirement of IFA supplementation can be inferred.

All the antenatal cases registered during the study period are included in the study without opting for sample. Study period is for one complete year. Antenatal cases moving out and moving into the area of study during the study period are excluded out of the study. Baseline data of antenatal cases is recorded with the help of a pre-tested questionnaire. Their blood samples are collected on the date of registration and analyzed for hemoglobin concentration by cyan meth hemoglobin method.

The criteria for determining the magnitude of anaemia recommended by the World Health Organization are based on the haemoglobin cut-off values for different ages and sex, with an additional epidemiological criterion for assessing the severity and magnitude of the problem in populations [20-22]. Those found to be anemic are analyzed for the type of anemia by peripheral smear examination.

First pack of IFA containing 30 tablets is given to the subject along with administration instructions. These steps are repeated on subsequent antenatal visits at 20, 32 and 36 weeks of pregnancy as per norms. During these subsequent visits hemoglobin concentrations are measured and compliance for IFA supplementation is enquired.

These women are followed up till the outcome of pregnancy. After delivery of the child the health status of mother and child are assessed.


The data thus obtained is subject to analysis for the effectiveness of IFA supplementation on the hemoglobin concentration and the outcome of pregnancy.

Results

A total of 1196 registered Antenatal cases (ANCs) were taken into study of which only 897 could be followed till the outcome of pregnancy. The minimum age was 18 yrs and maximum 38 yrs with 25 yrs as the most common age (17.7%). The mean age was 23.6 yrs with SD 2.97. Majority (43.8%) of the women belonged to O.C community and the least to Scheduled Tribes (2.3%) (table 1).

92 % of the families of the antenatal women were below the poverty Line (table 3). 41.5% are illiterate with only 0.7% with post graduate qualification (table 1). Majority (40.07%) of the women were second gravida and Primipara. Only 0.68% was grand multipara (table 1). With supplementation of IFA the Hemoglobin status of antenatal women has improved with every supplementation as shown in table 2.

When the blood samples of anemic women were subjected to analysis for type of anemia most common type of anemia was due to iron deficiency and the least common type is Megaloblastic (table 3). Out of all the risk factors complicating pregnancy most common risk factor complicating their pregnancy is anemia.

Of the 897 women followed till the outcome of pregnancy 6.5% pregnancies were aborted and 2.8% pregnancies resulted in still births with 90.7% of the pregnancies resulted in live births. Of the 839 deliveries conducted 95.1% of the deliveries were conducted in institutions. 3% of the babies born are low birth weight with no baby above 4 kg of weight.

Discussion

There were many dropouts from the study as many pregnant women moved to their maternal home for delivery. As normally observed there were few pregnancies below 19 years of age and above 30 years of age and majority from the 20 to 30 age group. Similar studies on prevalence of anaemia showed that highest numbers of the pregnant women are in the 21-25 age groups [23,24]. The RHC served rural areas with high backward and scheduled castes, so the pregnant subjects are also more from this area.

A study similarly showed Proportion of Schedule Caste population was higher than Kolkata’s average [25]. A very high percentage of below poverty line population are in the study as the RHC catered primarily to rural areas. Majority of the women were illiterate and the people with higher education decreasing gradually with minimum number of post graduates. A similar study showed that around 50% of pregnant were illiterate and the percent decreased as literacy levels increased [26].

Majority of the women were second gravida and primipara followed by primigravida. Multi gravid pregnancies were minimal. At the time of registration majority of the women were moderately anemic followed by mild and severely anemic women and very few normal women. In a study on haematological parameters in pregnant, on classifying the anemia as per the degree of severity, it was found that 59% were having moderate anemia while 6% women were having very severe anemia [27].

As the pregnancy proceeded and with IFA supplementation the anemic status gradually improved with every visit and at the end of the study majority of the women reached mild anemic state followed by normal women and only a few moderately anemic women. In a study on maternal anaemia, haemoglobin levels in the control group in 1st trimester showed a rise in 2nd trimester. Subsequently the haemoglobin level showed a rise in 3rd trimester and it was found to be similar to the 1st trimester [28].

No severely anemic women were present by the time of delivery. The difference observed in hemoglobin status at each visit was highly

significant (p<0.001). Peripheral smear was collected from all the anemic pregnant women at the first contact to identify the type of anemia. The results showed that majority were iron deficiency anemic with hypochromic and microcytic picture followed by dimorphic anemia where a picture of microcytic and megaloblastic anemia is seen.

In 2011 more than 50% of anaemia in pregnant women was due to iron deficiency in regions where fewer other causes were present [29]. Some of the anaemics were having hemolytic picture and the probable other causes include parasitic diseases such as malaria and genetically inherited haemoglobinopathies such as thalassaemia as mentioned in published studies [30]. Only a minority of women were purely megaloblastic.

This indicates that majority of the women suffered with iron deficiency anemia followed by mixed deficiency of iron, folic acid and or vitamin B12. Puolakka J etal. found that prevalence of iron deficiency is far greater than the prevalence of anemia and iron deficiency often develops during the later stages of pregnancy even in women who enter pregnancy with relatively adequate iron stores [31].

The most common risk complicating pregnancy from different published studies also turned out to be anemia. Also the second common risk is a history of previous caesarian section which clearly reflects the observation made by WHO of unnecessary caesarian sections in India. Majority of the pregnancies resulted in live births due to the availability of proper antenatal care and IFA supplementation. A minor of the cases resulted in abortions the cause for which could not be established.

Presence of anaemia was not significantly different between persons who had no spontaneous abortions and those who had one in a study on anemia of pregnancy [32]. More than 95% of the deliveries were institutional in nature. Only a few births were Low Birth Weight (LBW) babies while the majority children were of normal weight. In a study on iron supplementation, women taking iron supplements were less likely to have low birth weight newborns compared with controls [33].

Mean hemoglobin values at the time of registration did not vary significantly in respect to the age group, community, annual family income, and gravid status, and parity, outcome of pregnancy and birth weight of the baby.


The birth weight of the baby was not dependent on the mean hemoglobin levels at the time of registration or at the time of delivery. The mean hemoglobin levels were poor in post graduate degree holders than any other group and the difference is statistically significant which cannot be explained.

Conclusion

Majority of the women were in the 20-30 years age group, belonged to the scheduled castes community, from Below poverty line families and illiterate in their second gravida and primipara. At the time of registration majority of the women were moderately anemic majorly due to iron deficiency with anemia as the most common risk complicating pregnancy.

Mean hemoglobin values at the time of registration did not vary significantly in respect to the age group, community, annual family income, gravid status, parity, outcome of pregnancy and birth weight of the baby. Majority of the deliveries were institutional resulting in high live birth and normal birth weight rates.

Mean hemoglobin values at every visit varied significantly due to IFA supplementation. The birth weight of the baby did not dependent on the mean hemoglobin levels at the time of registration or at the time of delivery. All the women receiving IFA supplementation did not have adequate hemoglobin levels at the time of delivery and majority were mildly anemic.
