Abstract
Background. To investigate the effect of social service prenatal care (PNC) utilization on perinatal outcomes among women with socioeconomic problems in the Tokyo metropolitan area. Methods. Retrospective study. The study enrolled all women at our hospital who either attended PNC utilizing social services (attenders) or who did not attend PNC (nonattenders) between January 1, 2007, and December 31, 2010. We compared the maternal characteristics and perinatal outcome of attenders with those of nonattenders. Results. A total of 83 attenders and 45 nonattenders were enrolled. The mean gestational age at the first PNC visit was 31.1 weeks in the attenders. Attenders were found to have a lower incidence of preterm delivery, pregnancy-induced hypertension, emergency cesarean section, low birth weight, and the NICU admission than nonattenders (P < 0.05). Conclusions. The utilization of social service PNC greatly improved perinatal outcomes among women with socioeconomic problems problems in the Tokyo metropolitan area.
