A house-to-house survey of 1225 women in Manipur, a tiny state in North Eastern India was carried out to investigate birth interval patterns and its determinants. Using survival analysis, among the nine explanatory variables of interest, only three factors ? infant mortality, Lactation and use of contraceptive devices have highly significant effect (P<0.01) on the duration of birth interval and only three factors ? age at marriage of wife, parity and sex of child are found to be significant (P<0.05) on the duration variable. %N 4 %K Censored observation; Relative risk; Infant mortality; Breastfeeding %E Dr Srinivas Kakkilaya %V 9 %D 2011 %I BS Kakkilaya %L cogprints7245
