Effect of Social Service Prenatal Care Utilization on Perinatal Outcomes among Women with Socioeconomic Problems in the Tokyo Metropolitan Area

Table 4

Neonatal characteristics and indications for admission to the neonatal intensive care unit. Data shown include the number of neonates and are presented as the mean ± standard deviation. *Some neonates had more than one indication for admission to a neonatal intensive care unit. Attenders were found to have a lower incidence of low birth weight compared with the rate of nonattenders (𝑃<0.05). The incidence of admission to the NICU was higher for the nonattenders than for attenders (𝑃<0.05). Neonates from nonattenders were found to have a higher incidence of preterm delivery, low birth weight, neonatal infection and asphyxia (𝑃<0.05). Significance at 𝑃<0.05 was analyzed by Fisher’s exact test. NS: not significant.
