Risk factors for first-trimester spontaneous abortion and the role of preconception care.

ABSTRACT:

Background

Spontaneous abortion in the first trimester is a common adverse pregnancy outcome with significant implications for maternal health and public health practice. The description of associations with modifiable factors, including preconception care, can aid in planning strategies to improve pregnancy outcomes.

Methods

A retrospective analysis was conducted using data from 1,526 women, divided into two groups based on pregnancy outcomes: spontaneous abortion in the first trimester and live births. Binary and multivariate logistic regression analyses were performed to identify associations between factors (including preconception care) and the risk of spontaneous abortion in the first trimester.

Results

Age >35 years [[OR] = 2.02, 95% [CI] = 1.49-2.75], obesity
