|
|
Twins, triplets and conjoined twin totalling 274 pairs were studied in frequency and in relation to sex, and birth weight data and comparison of weight between co-twins have been calculated for 242 twin pairs.
from these obserations the following results have been drawn.
1. The frequency of twin of hospital delivery was 2.03%(1:49.3).
2. The ratio for male-male pairs, female-female pairs and male-female pairs was 3:3:2.
3. Weight of twin fetuses was similiar to single born fetuses at 30 weeks of gestational age, but after then, weight gain rate of twins was subnormal rate of growth during late gestation. At term the birth weight of twins was about 10% smaller than single born infants.
4. In comparison of birth weight between co-twins, 1st-born twin was slight larger than 2nd-born twin and there was about 50% a situation less than 10% in percent difference in birth weight between co-twins.
