Reproductive History and Burden of Adverse Pregnancy Outcomes in Women in Southern India (P11-006-19).

Abstract

Objectives\nTo characterize the reproductive history and pregnancy outcomes in women of reproductive age as part of an ongoing periconceptional surveillance program in Southern India.\n\n\nMethods\nParticipants were women of reproductive age (15-40 y) who were not pregnant or lactating and resided in households within the 50 km2 catchment area of our community-based research site in Southern India (n\xa0=\xa0813). After obtaining informed consent/assent, reproductive and obstetric histories were captured by a trained OB/GYN nurse via an electronic interviewer-administered questionnaire with the study participants.\n\n\nResults\nIn this population, most participants reported being married (76.1%) and having some formal education (83.7%), with a median age of 30 (interquartile range [IQR] 24, 36) years. The average age of menarche reported was 13.0 (IQR 12.0, 14.0) years, and the median age at first pregnancy was 19.0 (IQR 17.0, 21.0) years. A total of 76.6% of women reported at least one previous pregnancy; 7.9% were primiparous and 65.7% were multiparous, with a median of 2.0 (IQR 2.0, 2.0) children currently living per woman. Approximately 80% of women reported taking any iron (80.4%) or folic acid (77.9%) supplements at any point during pregnancy. To date, women reported a total of 1,614 previous pregnancies with 1,318 live births (n\xa0=\xa01,308 singleton live births, n\xa0=\xa05 sets of twins), 169 spontaneous abortions, 94 induced abortions, and 42 stillbirths. Fifteen pregnancies were reported to have been affected by birth defects (n\xa0=\xa01 cleft lip, n\xa0=\xa02 cleft palate with cleft lip, n\xa0=\xa02 talipes equinovarus/clubfoot, n\xa0=\xa03 spina bifida, n\xa0=\xa03 encephalocele, n\xa0=\xa01 anencephaly, and n\xa0=\xa03 other birth defects). A total of 48 women reported a biological relative with a birth defect diagnosed at birth.\n\n\nConclusions\nA substantial burden of birth defects was reported in this population (7 neural tube defects in 1,614 pregnancies). Findings from this survey will inform the establishment of an ongoing birth defects surveillance system and a randomized efficacy trial for prevention of anemia and birth defects in Southern India.\n\n\nFunding Sources\nCenters for Disease Control and Prevention.AF was supported by the National Institutes of Health #5 T32 HD087137.
