Abstract
OBJECTIVE: This analysis describes the interpregnancy interval (time from livebirth to subsequent conception) in a convenience sample of women living in Southwest Guatemala and the association of antepartum characteristics and postpartum outcomes with a short interpregnancy interval (< 24 months). METHODS: This is an observational study of a convenience sample of women enrolled in the Madres Sanas community antenatal/postnatal nursing program supported by the Center for Human Development in Southwest Trifinio, Guatemala, between October 1, 2018 and October 1, 2019. We observed the distribution of interpregnancy intervals among the population of women with a reported date of last live birth, and used bivariate comparisons to compare women with a short interpregnancy interval (< 24 months) to those with an optimal interval ([Formula: see text] 24 months) by antepartum, obstetric and delivery, and postpartum outcomes. RESULTS: 171 parous women enrolled in the Madres Sanas program between October 1, 2018 and October 1, 2019, and reported the date of their last live birth. One hundred-forty-one (82.5%) women delivered and 130 of those women (92.2%) were seen for their 40-day postpartum visit. The mean interval was 37.1 months with a 22.1-month standard deviation. The median interval was 33.7 months with an interquartile range of 19.6-49.5 months. Among these women, 113 (66.1%) the interpregnancy interval was at least 24 months. The only covariate of all sociodemographic, obstetric and antepartum, delivery, and postpartum characteristics that differed between women who achieved an interval ([Formula: see text] 24 months) compared to those that did not (< 24 months), was age (median 22.9, interquartile range (IQR) [19.1,27.0] vs median 24.8, IQR [21.6,27.9], respectively, p = 0.006). A regression model found that with each increasing year of age, the interpregnancy interval increases by 1.08 months, p = 0.025. CONCLUSION: Among parous women, two-thirds of women space pregnancies at least 24 months. Older women were more likely to have a longer interval between live births.
