19世紀スウェーデンにおける熟練助産師による出産介助の人口統計学的差異：乳児生存率にどのような影響を与えたか？

This study examines the influence of social and demographic factors on the utilization of trained midwives in Sweden during the latter half of the nineteenth century. It also examines differences in neonatal, post-neonatal, and child mortality between births attended by trained midwives and those without such assistance.

The analysis is based on population data covering 116,597 births. Logistic regression models were used to estimate the association between midwifery, background characteristics, and mortality outcomes.

The findings reveal substantial regional variation in the use of trained midwives throughout the study period. Births attended by trained midwives were more common among high-risk births and among married women compared to unmarried women. Regarding mortality, the results show an increased risk of post-neonatal mortality during the first period (1860-1869), and a decreased risk of neonatal mortality during the final period (1890-1894).

The study highlights the evolving role of trained midwives in childbirth practices in 19th-century Sweden and their contribution to reducing infant mortality, which coincided with the introduction of antiseptic methods from 1880 onward.
