Dietary Supplements Intake During Pregnancy Among Pregnant Women in Ethiopia

Introduction: Pregnant women are expected to take one or more dietary supplements (DS) like iron, folic acid, zinc, calcium, magnesium, prenatal vitamins, etc. for maternal and child health during pregnancy. Despite its growing use in Ethiopia, data concerning currently marketed maternal DS products have not been intensively investigated so far. Taking into consideration the existing problem, this study was set out to assess the prevalence and commonly used DS during pregnancy in a referral hospital in Ethiopia. Methods: A facility based cross-sectional study was employed to conduct this study from November 2020 to January 2021. The sample size was obtained by using the single population proportion formula and participants were selected and approached by using a systematic random sampling technique. Data were collected through a semi-structured interviewer-administered questionnaire. Descriptive statistics including frequencies and percentages were used to describe continuous and categorical variables and multivariate logistic regression was used to observe the association of the independent variables to the dependent variable. Results: The overall prevalence of DS use was 84.2% and the most used product was Fefol (iron and folate supplement) (62.4%). A majority (87.8%) of DS products were obtained by prescription. In multivariate regression analysis, DS use during pregnancy was significant among nulliparous women and women who went to college and above [adjusted odds ratio (AOR): 8.142, 95% confidence interval (CI) (1.298-51.070)] and [AOR: 9.259, 95% CI (1.998-42.906)], respectively. Conclusion: Even though the prevalence of DS practice showed improvement among the study participants, the duration of the DS intake is less than that recommended by the WHO. Pregnant women who did not have birth before and who went to college or above showed significant association with the use of DS.
