Recent federal and state policy has expanded Medicaid eligibility to provide health insurance coverage for pregnant women with family incomes below 133 percent of the federal poverty level. It has yet to be determined how such expanded coverage will affect enrollment in Medicaid or use of prenatal care. Using 1983 data from three states with widely divergent Medicaid programs--including one that already had most of the expanded eligibility options available today--this study found that about 40-60 percent of women who were covered by Medicaid at the time of their deliveries had not been enrolled in the program when they became pregnant. In addition, a large number of women did not receive Medicaid-covered prenatal care early in pregnancy, even though they were enrolled at that time. Almost all women in the study group visited more than one ambulatory care provider at some time during the nine months before birth and one year following birth; 29-51 percent visited more than one hospital outpatient department.
近期的联邦和州政策扩大了医疗补助计划的资格范围，为家庭收入低于联邦贫困线133%的孕妇提供医疗保险。目前尚不清楚这种扩大后的保险覆盖范围将如何影响医疗补助计划的参保情况或产前护理的使用。本研究使用了来自三个医疗补助计划差异很大的州的1983年数据——其中一个州已经具备了如今大多数扩大后的资格选项——发现约40%至60%在分娩时享受医疗补助计划覆盖的女性在怀孕时并未参保。此外，大量女性在怀孕早期并未接受医疗补助计划覆盖的产前护理，尽管她们当时已参保。几乎所有研究组中的女性在分娩前九个月和产后一年内的某个时间都拜访过不止一位门诊护理提供者；29%至51%的女性拜访过不止一个医院门诊部。
