[251-POS]: Risk of XXXX compared to number of prenatal visits.

@entity1 @entity3036 @entity3152 @entity101
OBJECTIVES: To compare the relative risk of @entity3036 and frequency of prenatal visits. METHODS: We evaluated the risk of gestational @entity101 with the number of prenatal visits in 4,247,694 delivered @entity1 included in the CDC 2008 Vital Stats dataset. The incidence of @entity3036 among subgroups of @entity1 defined by their number of prenatal visits was calculated. Relative risks were determined for each subgroup by comparing the incidence of @entity3036 in each subgroup compared to those @entity1 with 13-14 visits (reference group). These groups were (1) no visits, (2) 1-2 visits, (3) 3-4 visits, (4) 5-6 visits, (5) 7-8 visits, (6) 9-10 visits, (7) 11-12 visits, (8) 13-14 visits {reference group}, (9) 15-16 visits, (10) 17-18 visits, (11) 19 or more visits. RESULTS: The relative risk of @entity3036 increased as the number of prenatal visits decreased, with the highest risk among those @entity1 who had no prenatal visits (RR=2.16, 95% CI=1.90-2.45). The relative risk of @entity3036 also increased as the number of prenatal visits increased above 13-14 visits. The highest risk was for those @entity1 with 19 or more visits (RR=2.34, 95%, CI=2.13-2.58). CONCLUSIONS: Fewer prenatal visits may be associated with a higher risk of @entity3036 . This may be due to iatrogenic @entity3152 or poor @entity1 compliance. @entity3036 may also be associated with an increased number of prenatal visits. This may be due to close monitoring of a high risk @entity1 . DISCLOSURES: E.T. Greeley: None. K.L. Terry: None. J.V. Spencer: None.
