Data on approximately 45,000 North Carolina women who gave birth in 1989 and 1990 and received prenatal care in public health facilities were studied to assess the effects in a low-income population of prior family planning services on low birth weight and adequacy of prenatal care. Women who had used family planning services in the two years before conception were significantly more likely than those who had not used such services to have a birth-to-conception interval of greater than six months. They were also more likely to receive early and adequate prenatal care and to be involved in a food supplement program and maternity care coordination. In addition, the family planning participants were less likely than the nonparticipants to be younger than 18 and were somewhat less likely to deliver a low-birth-weight infant. Though the results of this retrospective study must be interpreted with caution because of such factors as self-selection into family planning programs, they suggest that family planning services may improve birth weight and use of prenatal health services among low-income women.
对1989年和1990年在北卡罗来纳州生育且在公共卫生机构接受产前护理的约45000名女性的数据进行了研究，以评估先前计划生育服务对低收入人群低出生体重和产前护理充分性的影响。在受孕前两年使用过计划生育服务的女性比未使用此类服务的女性更有可能有超过六个月的生育间隔。她们也更有可能接受早期和充分的产前护理，并参与食品补充计划和孕产妇护理协调。此外，参与计划生育的女性比未参与者年龄小于18岁的可能性更小，且分娩低体重婴儿的可能性也略小。尽管由于诸如自行选择参与计划生育项目等因素，这项回顾性研究的结果必须谨慎解读，但它们表明计划生育服务可能会改善低收入女性的出生体重和产前健康服务的使用情况。
