Metabolic scaling and twin placentas. Academic Article uri icon

Overview

abstract

  • OBJECTIVE: Do monochorionic (MC) and/or dichorionic (DC) twins show allometric scaling between placental and birth weight (PW, BW)? METHODS: We extracted BW, PW, gestational age (GA) and cord insertion type from 52 MC to 310 DC twins to calculate β. DC twins were analyzed as summed and as individuals if placentas were separate. RESULTS: Mean β for MC (0.78 ± 0.02), DC summed (0.78 ± 0.02), and DC with separate placentas (0.77 ± 0.03 and 0.76 ± 0.04) all non-significant. GA, summed BWs, total PW, BW discordance, and cord insertion sites did not differ between twin types or with β. CONCLUSION: MC and DC twins show allometric scaling similar to singletons.
