Abstract

Objectives: This report explores changes in the overall rate of triplet and higher-order births from 1998 to 2023 by detailed plurality, maternal race and Hispanic origin, and age.

Methods: Data are from the National Vital Statistics System birth files. Triplet and higher-order birth rates (number of triplet and higher-order births per 100,000 births) from 1998 to 2023 are presented. Also presented are the number of triplet, triplet and higher-order, and quadruplet and higher-order births, and triplet and higher-order multiple birth rates by maternal race and Hispanic origin and maternal age for 1998, 2009, and 2023.

Results: From 1998 to 2023, the triplet and higher-order multiple birth rate declined 62%, from 193.5 per 100,000 total births to 73.8; the largest declines were from 2009 to 2023. The number of triplet and higher-order births declined from 7,625 to 2,653. Declines in triplet and higher-order birth rates were observed for White non-Hispanic (71%) and Hispanic (25%) mothers, while the rate for Black non-Hispanic mothers increased (25%). Triplet and higher-order birth rates declined for all age groups 20 and older from 1998 to 2023, and the largest declines were for mothers age 30 and older.

1998-2023 年美国三胞胎和高阶多胞胎数量的下降。

目标：本报告探讨了 1998 年至 2023 年期间三胞胎和高位胎儿总出生率的变化情况，并按详细的多元性、母亲种族和西班牙裔以及年龄进行了分类：数据来自国家人口动态统计系统的出生档案。方法：数据来自全国人口动态统计系统的出生档案。数据显示了 1998 年至 2023 年的三胞胎和高胎次出生率（每 10 万名新生儿中三胞胎和高胎次出生的数量）。此外，还列出了 1998 年、2009 年和 2023 年三胞胎、三胞胎及三胞胎以上、四胞胎及四胞胎以上的出生人数，以及三胞胎及三胞胎以上的多胎率，并按产妇种族、西班牙裔和产妇年龄进行了分类：从 1998 年到 2023 年，三胞胎和高位多胞胎的出生率下降了 62%，从每 10 万名新生儿中有 193.5 例下降到 73.8 例；2009 年到 2023 年的降幅最大。三胞胎和高位多胞胎数量从 7 625 例降至 2 653 例。非西班牙裔白人（71%）和西班牙裔（25%）母亲的三胎及三胎以上生育率有所下降，而非西班牙裔黑人母亲的三胎及三胎以上生育率则有所上升（25%）。从 1998 年到 2023 年，所有 20 岁及以上年龄组的三胎和高次生育率都有所下降，其中 30 岁及以上年龄组的母亲下降幅度最大。
