Consanguineous marriage and early pregnancy loss in rural to
Consanguineous marriage (CM) has been linked to spontaneous abortion (SAB). Investigators aimed to determine the relationships between CM and SAB in a prospective pregnancy cohort study in Telangana State, India.

Data from 661 participants aged 15–35 years in the Longitudinal Indian Family hEalth (LIFE) study actively followed for pregnancy and pregnancy loss were analyzed. SAB was classified as early (<8) or late (8–22) weeks gestation. They used logistic regression to model the relationships between CM, defined by first-cousin marriage, and SAB, adjusted for maternal age.

Women in CM were at a modestly increased risk of any and early SAB compared to women in non-CM, although results were not statistically significant. There was no relationship between CM and late SAB.

Among couples in southern India, there was a modest increase in early but not late SAB among CMs which may be explained by the expected influence of chromosomal abnormalities and lethal homozygous recessive disease on early loss.
