The postnatal period is critical for preventing maternal and neonatal morbidity and mortality. Globally, a significant proportion of maternal and neonatal deaths occur within the first 6 weeks after delivery. Timely and adequate postnatal care (PNC) can detect and manage life-threatening complications; however, service utilisation remains alarmingly low in many low- and middle-income countries, including Saudi Arabia. Addressing the behavioural and perceptual factors that influence service use is essential for improving health outcomes.

This study aimed to assess mothers’ utilisation of PNC services and examine how their health beliefs and sociodemographic characteristics influence this behaviour.

A cross-sectional study guided by the Health Belief Model (HBM) was conducted to explore predictors of PNC utilisation.

Eight primary healthcare (PHC) centres were randomly selected from 179 PHC centres distributed in the different governorates of the Jazan region of Saudi Arabia.

A total of 464 mothers were surveyed between October and December 2023 using an interviewer-administered questionnaire.

The primary outcome was PNC utilisation, defined by the number of postnatal visits. The independent variables included sociodemographic characteristics and HBM constructs (perceived susceptibility, benefits, barriers and cues to action).

In terms of PNC utilisation, 80.0% of participants had two or fewer postnatal visits, whereas 20.0% had three or more postnatal visits. Perceived barriers had the strongest influence (mean score 2.51±0.87), followed by cues to action (2.43±0.89), susceptibility (1.92±0.72) and benefits (1.86±0.64). In the multivariate analysis, perceived barriers, cues to action and perceived susceptibility were significantly associated with PNC utilisation, with adjusted ORs of 1.679 (95% CI: 1.007 to 2.799), 0.470 (95% CI: 0.256 to 0.863) and 0.405 (95% CI: 0.197 to 0.832), respectively.

PNC utilisation in the Jazan region remains suboptimal. Perceptual factors, particularly barriers and cues to action, play a central role in service use. Health interventions targeting these beliefs and improving follow-up mechanisms may help increase PNC engagement and improve maternal and infant health outcomes in Saudi Arabia.
