Childbirth spacing in a rural community of Delhi: profile in various marriage cohorts by decades. Indian Pediatrics. 1989 Sep; 26(9): 894-9http://imsear.searo.who.int/handle/123456789/15002Complete retrospective fertility histories of 843 ever married women of two villages in Delhi, obtained through house to house survey, were analysed to study various marriage cohorts by decades for trends of child birth spacing over a period of 60 years from 1921 to 1980. Spacing between consummation of marriage and first child birth gradually declined over the last 6 decades. For all other subsequent livebirths remained constant at an average of nearly 30 months. Irrespective of the reasons for such a trend, much more efforts are required to be put in to increase child spacing.engAdolescentAdultBirth IntervalsCohort StudiesDeveloping CountriesFemaleHumansIndiaRetrospective StudiesRural PopulationJournal Article
