The Growth Discordant Twin

Objective: To compare neonatal morbidity and mortality between hospitalized discordant and concordant preterm twin pairs.Study Design: This was a retrospective, hospital-based study of preterm twins, followed in neonatal intensive care unit. Twins were classified as discordant when the difference in birth weight was >15%. Morbidity and mortality rates were compared between discordant and concordant groups.Results: Of 136 preterm twins in the study, 54 were discordant and 82 were concordant. In discordant twins hypoglycemia and cesarean delivery rate was higher than concordant pairs. The mortality rate did not differ between concordant and discordant groups.Conclusions: Hospitalized preterm discordant twin pairs have an increased risk of hypoglycemia compared to concordants. Discordant growth is not a risk factor for prolonged hospitalization and increased mortality.

“…Three definitions of discordant birthweights have been used routinely (Blickstein & Lancet, 1988). The firstthe so-called "absolute" definition records the absolute birthweight difference.…”

“…The cumulative frequency curve in Figure 1, shows that about 75% of twins exhibit < 15% discordance, an additional 20% are 15-25% discordant, and about 5% are more than 25% discordant. These levels of discordance have been referred to as concordant, mild discordant, and severe discordant levels (Blickstein & Lancet, 1988). We have recently compared the percent definition (> 25% discordance) with the 95th percentile of discordance by gestational age (Kalish et al, 2002).…”

“…Using a birthweight difference of more than 25% as a cutoff point, Blickstein et al, compared two cohorts of twin pairs, one from four different perinatal centers (United States, Poland, and two from Israel) and the other from a Swedish population-based data; they found birthweight discordance of 11% in the former and 12% in the latter. [3] Some investigators have reported that divergent fetal growth increases the risk of fetal death [2,4,5] and other adverse outcomes such as prematurity [4,6] with its attendant morbidity and mortality. In a study of 122 live-born twin pairs delivered between 25-and 34-week gestation, Cheung et al [7] reported that birthweight discordance greater than 30% was associated with congenital anomalies and complications of prematurity.…”

Background: Birthweight differences in twin pairs influence their perinatal outcome as well as growth and development. Growth-discordant twins have not been well characterized in our local environment. Objective: To determine the frequency of birthweight discordance in live-born twin pairs and document some factors that may infl uence it. Methods: In this cross-sectional study, 104 live-born twin pairs were recruited and their intrapair birthweight differences were determined. Twin pairs whose birthweight difference was 15% or more, using the larger infant as the growth standard, were designated as discordant. The maternal age, parity, and birth order of the heavier twin were noted. Results: The prevalence of birthweight discordance was 28.8% when a 15% cut-off point was used but dropped to 9.6% when a 25% cut-off point was applied. Grand multiparity was associated with a signifi cantly increased risk of delivery of discordant twins. Same-sex twin pairs accounted for 60% of all cases of birthweight discordance. Conclusion: Birthweight discordance is common in twin gestations in Benin City, especially among grand multiparous women.
