目的:了解活产双胎大婴儿与小婴儿出生体重差异。方法:随机抽取活产双胎产妇病历65份65对活产双胎新生儿,分析活产双胎大婴儿与小婴儿出生体重差异。结果:女性双胎婴儿出生体重差异程度﹥10%占54.55%(12/22),<10%占45.45%(10/22);异性双胎婴儿出生体重差异程度﹥10%占15.00%(5/16),<10%占68.75%(11/22)。男性双胎婴儿出生体重差异程度﹥10%占14.81%(4/27),<10%占85.19%(23/27)。其构成比有统计学差异(χ2=8.75,P<0.05)。双胎生长不一致发生率为10.77%(7/65)。大婴儿体重(2 448.46±533.02)g,小婴儿体重为(2 189.54±501.85)g。结论:出生体重差异程度,女性双胎婴儿﹥异性双胎婴儿﹥男性双胎婴儿。活产双胎大婴儿与小婴儿出生体重均差为258.92 g。
OBJECTIVE: To understand the differences in birth weight between twins born alive and babies. Methods: A total of 65 pairs of neonatal twins, 65 live birth twins, were randomly selected to analyze the differences in birth weight between twins and twins. Results: The differences of birth weight among female twins were 54.55% (12/22), <10% (45/45) (10/22), and 10% (15.00%) for twins / 16), <10% accounted for 68.75% (11/22). The birth weight difference of male twins babies was> 10%, accounting for 14.81% (4/27) and <10%, accounting for 85.19% (23/27). The constituent ratio was statistically different (χ2 = 8.75, P <0.05). Twins growth inconsistent incidence was 10.77% (7/65). Big baby weight (2 448.46 ± 533.02) g, small baby weight (2 189.54 ± 501.85) g. Conclusions: Differences in birth weight, twins in females> twins in twins> twins in males. The difference in birth weight between twins with live births was 258.92 g.
