Background Perinatal deaths have been more difficult to prevent than infant deaths in low-income countries due to its close relation to poor maternal outcome. The aim of the study was to perform a comprehensive population-based analysis of perinatal mortality in a high mortality setting and to determine the impact of midwifery-assisted home deliveries. Method The study design was a community-based cohort study. In all, 4876 perinatal deaths were recorded among 116 211 newborns in the districts of S undsvall and Skelleftea in northern Sweden during the years 1831-1899. Relative risks, 95% CI, population attributable proportions and prevented fractions were calculated. Results The overall perinatal mortality rate was 42.0 per 1000 births. A previous stillbirth represented one of the most important risk factors (RR=3.25,95% CI : 2.97-3.56), with a population attributable proportion of 7%. Two or more previous stillbirths gave an RR of 8.50 (95% CI : 7.58-9.53) and a population attributable proportion of 4%. There was an increased risk of perinatal mortality for mothers over 35 years old, the primiparous and the unmarried, while grandparous women had a higher perinatal mortality that was accounted for completely by a poor history of previous stillbirths and infant deaths among these women. The children of crofters, farmers and workers had higher perinatal mortality, but area had no significant impact. (...)
