Predictors of antibiotic use in pregnant women attending Najran University Hospital, Saudi Arabia.

Objectives: To determine the prevalence of antibiotic use by pregnant women in Najran, Saudi Arabia.

Methods: A total of 125 women aged 18 to 45 with a full-term pregnancy participated from October to December 2019. Age, order of current pregnancy, body mass index (BMI), history of miscarriage, and comorbidity were used to estimate antibiotic use.

Results: The majority were Saudis (67.2%), aged 30-35 (39.2%) years, with no history of miscarriage (53.6%), second order of pregnancy (26.4%), and going through weeks 20-25 of pregnancy (21.6%). A total of 26.4% of pregnant women had antibiotic prescriptions in the study population. Pregnant women under 30 years were less likely to receive antibiotics.

Conclusion: The results found an association between maternal age, order of pregnancy and antibiotic use during pregnancy. An association was observed between maternal BMI and the occurrence of adverse drug reactions after antibiotic use. In addition, a history of miscarriage was negatively associated with the use of antibiotics during pregnancy. These predictors of antibiotic administration have the potential to serve as general health indicators and to direct preventative strategies aimed at increasing the rational use of antibiotics.
