ABSTRACT
PURPOSE:
To investigate the incidence of intra-twin birth weight discordance and its association with infantile gender and birth order.METHODS:
We used the data of birth from 2008 to 2013 of Korea Statistics (38,140 pairs of twins). Adjusted logistic regression analyses were performed to describe the birth weight discordance (> or =25%) according to infantile gender and birth order (twin A 1st, twin B 2nd). Birth weight discordance was calculated as 100 x (birth weight difference/birth weight of the heavier twin).RESULTS:
Twin A (mean 2.431 kg) was heavier than twin B (mean 2.359 kg), and the weight difference was 0.281 kg on average. Overall incidence of birth weight discordance was 8.3 percent. The incidence of discordance was 8.8 percent among unlike-sexed pairs and 8.0 percent among like-sexed pairs. Twins with birth weight A> or =B (10.2 percent) showed higher incidence of discordance than twins with birth weight A or =B) as compared to like-sexed twins (female-female) with birth weight (ACONCLUSION: Birth weight discordance was associated with unlike-sexed twin pairs and difference of inter-twin birth weight by birth order. However, close attention should be paid to the discordance of twin body weight to reduce the risk of adverse outcome.
