Study on the outcome of pregnancies for one year in Dehradun city

Data on the outcome of pregnancies and birth weight of neonates for one year from the government women hospital, Dehradun (U.P.) are analysed. The frequency of live births, stillbirths, twin births and abortions are found to occur higher in autumn. This may be due to higher number of marriages in winter months and higher conception rate in cooler months. The live birth sex ratio is found to be at par with the other world populations. The sex ratio for single live births as well as stillbirths is lowest in winter and for twin births, it is lowest in summer. Single live born neonates are heavier than the stillborn and twin born neonates. Summer live born and winter stillborn single neonates are heavier than those born in other seasons.
