Prevalence
of anemia during pregnancy: Results of laboratory data analysis from a Primary
Health center of Goa
Abstract:
Introduction:
Globally anemia affects 1.62 billion people which correspond to 24.8% of the
population. It is more prevalent in pregnant women and young children. [1]
Objective:
Study was conducted to know the status of anemia in the antenatal cases
registered at the Primary health Center.
Methods:
Anaemia was diagnosed by estimating the haemoglobin
concentration in the blood with the use of the indirect cyanmethemoglobin
method, data generated at laboratory was
collected and analyzed.
Results:
During study period 649 Antenatal cases laboratory data were available, of this
37.6% were mild anemic, 7.4% having moderate anemia, overall prevalence of
anemia was 45.10%% in Antenatal cases.
Conclusion:
Present study aims at only to find prevalence of anemia among antenatal cases,
which was 45.10% slightly higher than NFHS III data, which was 36.9% among
pregnant women. [2] Further detail assessment of the various factors
involved in anemia need to be study among antenatal women.
Key
words: Anemia, antenatal cases, pregnancy.
Introduction:
Anemia is a
global public health problem affecting about 1.62 billion people which
corresponds to 24.8% of the population, from both developing and developed
countries with major consequences for human health as well as social and
economic development. It is more prevalent in pregnant women; over 80% of the
countries have a moderate or severe public health problem.[1] In
the low socio-economic groups 50-60 per cent of women are anemic in the last
trimester of pregnancy. Anemia is associated with high incidence of premature
births, postpartum haemorrhage, puerperal sepsis and thromboembolic
phenomena. [3]
Objectives:
To study the prevalence of anemia in
antenatal cases.
Methodology:
This study was conducted at Sankhalim Primary
Health Center of the North Goa. The area under primary health center mostly
comprise of rural areas, catering approximately 40,000 populations with more
than 70% population belongs to low and middle socio-economic class. Primary
Health Center is the nearest government health facility available to this
people. Average 64 new antenatal cases (ANC) are registered per month to this
PHC. All the Antenatal cases were provided with iron and folic acid
supplementation from 13th week onward.
During their first visit, hemoglobin
estimation is done by only laboratory technician by cyanmethemoglobin
method. Data which was generated in the laboratory was compiled and analyzed
for the prevalence of anemia.
Data was collected for the period of
10 months from January 2010 to October 2010 and analyze for prevalence.
Anemia in pregnant women is defined as
hemoglobin level below 11gm%.[4] and further classified as mild (
9-10.9 gm%), moderate (7-8.9 gm%) and severe anemia (less than 7 gm%).
Results and
Discussions
During study period 649 Antenatal
cases data were available at the Primary health Center of which, 88.9% Antenatal
cases were Hindu and 10.9% Muslim. Of the 649 Antenatal cases, 86.5% Antenatal
cases belongs to 20 to 30 years of age group and only 2.0% was less than
20years of age. Mean hemoglobin was 10.7gm% (SD of 1.37gm %) and mean age was
25.5 years (SD of 4.5yrs)
Total prevalence of anemia among ANC
was 45.10%, with mild anemia in 37.6% cases and 7.4% had moderate anemia. In
age group of 20-25 years, 45.5% of the 358 Antenatal cases were anemic and 47.3%
were having anemia in the age group 26-30years.Anemia in less than 20 years
were 53.9% of 13 Antenatal cases (P 0.778).
As per Family Welfare statistics of
India 2009, for North Goa, anemia among ever married women aged 15-49 yrs were
38.9% (NFHS III) and 36.4% (NFHS II).Pregnant women age 15-49 who are anaemic
are 36.9% NFHS III ( urban-43.3% and rural-26.1%), NFHS II-35%.[2] Total
577 Hindu Antenatal cases registered at PHC, of which 44.7% were anemic and 33%
of the 71 Muslim Antenatal cases were anemic.(P 0.925)
Prevalence of anemia in Valencia study
was 34.44%, and of which 1.8% had severe anemia. [5] Similarly in Tanzania study 23 % of
pregnant women had Hemoglobin less than 11gm%. [6]
G.S. Toteja et al study shows that the prevalence of anaemia among the 6,923
pregnant women from the 16 districts was 84.9% and overall prevalence of
moderate and mild anaemia in pregnant women was 60.1% and 11.8% respectively.
[7] Prevalence of anaemia in this study was
more than NFHS III.
Present study
had only assessed the prevalence of anaemia in antenatal cases at a point of
time, further follow up and pregnancy outcome with impact on newborn require to
be studied.
