Estimation of Survival Function of Duration of Breast-feeding in the Presence of Some Censored Data
N. Sanajaoba Singh and N. Sharat Singh
 
Abstract: Breast-feeding (BF) has direct impact not only on the health of young children but on reducing fertility through duration of Post Partum Amenorrhoea (PPA).The present study is to examine the pattern of BF and its associated factors by estimating the survival functions of duration of BF. A cross sectional study of 1225 ever married women of reproductive age having at least one live birth was conducted during 2008-09 in valley districts of Manipur under cluster sampling scheme. Survival analysis techniques using life table method and Cox’s pH Model has been adopted through SPSS vs. 16. The median duration of BF is found to be 20.37 months. Place of residence (p<0.01), employment status (p<0.01), educational level (p<0.05), family income (p<0.05) and parity (p<0.05) have their significant impacts on the dynamics of BF duration. The current duration of BF is about 20 months which is far behind the National figure of 25 months and WHO recommendation of 24 months. Thus, program implementers are needful to promote BF at an adequate level.
