Journal Title: Healthline - Year 2012, Vol 3, Issue 2
Abstract
[b]Background:[/b] India contributes towards 25 per cent of deaths in the world due to the pregnancy and related health problems. We aimed to observe the changes of level of prevalence of Anemia among lactating and pregnant women over the last decades in India. [b]Methods:[/b] The National Health Surveys have been conducted in India during 1998 and 2006 namely NFHS-2 and NFHS-3. A total of 1751 women have been studied by team of Healthcare & Research Association for Adolescents Noida & Nutrition Foundation of India (H. R. A. A. N & N. F.I) from seven states of India in 2004. The changes of prevalence rate of Anemia among pregnant and lactating women have been explored in this work. The Bayesian approach in the parametric model has been applied to deal with coarse data problem. [b]Results: [/b]The overall prevalence of Anemia in 1998, 2004 and 2006 are observed with 55 per cent, 52.44 per cent and 84.0 per cent respectively. The posterior Mean (SD) of mild, moderate and severe Anemic status among pregnant and lactating women have been found with [1.1(0.52), 0.47 (0.53), -3.9(0.24)] and [0.69(1.06), -2.69(0.21),-.25(0.83)] in 2006 with respect to 2004 study. [b]Conclusion: [/b]Some improvement on nutritional status has been found on pregnant women. However, no significant change of Anemia prevalence has been observed on lactating women during the last few decades in India.
