There was a slight decrease (n=23) in the 11,170 live births in South Dakota between 2022 and 2023 with the state's birth rate falling to its lowest rate (12.2 per 1,000 population) in its recorded history. The state's percentage of American Indian, Black and Other (AIBO) live born infants is declining and currently comprises 21% (down from 25% in 2017) of the 2023 birth cohort with American Indians decreasing in their respective contribution to it as diversity of newborns is increasing. Though lower than observed nationally, the state's newborns with birth weights of 1,500 to 2,499 grams are also increasing. In 2023, AIBO, compared to White newborns, have a higher percent of very low birth weight (2% vs 1%) and mid low birth weight (7% vs 6%). First trimester prenatal care is used by over 80% of White pregnant women but only 53% of AIBO pregnant women for whom 8% received no prenatal care. In 2023, there was a decrease in the state's infant mortality rate from 7.8 to 6.4 (deaths per 1,000 live births 0 to 364 days of life) with declines noted in both the neonatal (0 to 27days of life) and the post neonatal (28-364 days of life) period. Between the years 2019-2023, the state's rates of death for AIBO infants in the neonatal and post neonatal periods were significantly higher than these rates for White infants. Contributing to this observation are higher AIBO than White rates of infant deaths for perinatal causes, congenital anomalies, sudden unexpected infant death (SUID). The racial disparity in infant mortality has recently become more apparent, especially in the post neonatal period when SUIDs are the leading cause of death.
2022年至2023年期间,南达科他州的11170例活产数略有下降(n = 23),该州的出生率降至有记录以来的最低水平(每千人口12.2例)。该州美洲印第安人、黑人及其他种族(AIBO)活产婴儿的比例正在下降,目前占2023年出生队列的21%(低于2017年的25%),随着新生儿多样性的增加,美洲印第安人在其中的贡献也在减少。尽管低于全国水平,但该州出生体重在1500至2499克之间的新生儿数量也在增加。2023年,与白人新生儿相比,AIBO极低出生体重儿(2%对1%)和中低出生体重儿(7%对6%)的比例更高。超过80%的白人孕妇接受了孕早期产前护理,但只有53%的AIBO孕妇接受了该护理,其中8%的孕妇未接受任何产前护理。2023年,该州的婴儿死亡率从7.8降至6.4(每1000例0至364天的活产死亡数),新生儿期(0至27天)和新生儿后期(28至364天)均有所下降。在2019年至2023年期间,该州AIBO婴儿在新生儿期和新生儿后期的死亡率显著高于白人婴儿。围产期原因、先天性异常、婴儿猝死综合征(SUID)导致的AIBO婴儿死亡率高于白人婴儿,这一现象导致了上述观察结果。婴儿死亡率的种族差异最近变得更加明显,尤其是在新生儿后期,SUID是主要死因。
