The prevalence of short inter-pregnancy interval and its associated risk factors among women attending primary health care centers of NGHA in Jeddah, Saudi Arabia: A cross-sectional study

Abstract

Background: The inter-pregnancy interval (IPI) refers to the time between one pregnancy and the next. Studies have shown that IPIs shorter than 18 months are linked to negative outcomes, such as preterm delivery, infant mortality, and small-for-gestational-age birth. The aim of this study was to measure the prevalence and risk factors of short inter-pregnancy intervals among women receiving care at primary health centers in Jeddah, Saudi Arabia.

Methods and material: This is a cross-sectional study conducted at primary health care centers among mothers with a history of giving birth to at least one child and having two successive pregnancies. The data was collected through face-to-face interviews using a structured questionnaire. Statistical analysis was carried out using RStudio (R version 4.3.0).

Results: A total of 300 responses were analyzed. The prevalence of short IPI was 36.0%, 31.0% had prolonged IPI, and 33.0% had optimal IPI. Lower educational level, unemployment as a student, low or middle income, a rise in the number of children, typically more than six, and an increase in the number of male offspring, mostly four or more, lack of breastfeeding, and breastfeeding duration have all been identified as statistically significant risk factors for short IPIs.

Conclusions: Short inter-pregnancy interval is prevalent in Jeddah city, which can negatively impact the perinatal outcomes. Addressing the risk factors and providing proper education in antenatal and postnatal clinics to reduce the number of unintended pregnancies can help in decreasing the number of short inter-pregnancy intervals and improving maternal and fetal outcomes.
