Abstract
The data on twin births from four different places in Northwest India were analyzed to study epidemiological characteristics of twinning. Gujjars manifested the highest incidence of twinning (30.2 per 1000 births). The twinning rate at Amritsar for the year 1987 was 19.20. At Bathinda and Jammu, the average twinning rate over the period 1984–93 were 10.70 and 11.40 respectively. Stillbirth rate among twins was much higher in Gujjars as compared to other three samples. Regional trends of twinning rate showed the highest incidence in the state of Uttar Pradesh, while the lowest in Tamilnadu. There were no significant differences between states for MZ twinning rate, while differences in the DZ twinning rate were significant in some instances. Maternal age and parity specific twinning rate showed the highest incidence at parity 4 and in the maternal age group 30–34 years. There was evidence of both seasonality and secular trends in twin births. The highest incidence of twin births over the period 1984–93 was noted in the summer season followed by rainy season, while the lowest in autumn. The average incidence of twinning in the Jammu region decreased from 13.76 during the years 1984–89 to 9.07 during the year 1990–93.
