Background: The use of herbal medicine is increasing globally, particularly in developing countries including Ethiopia, yet little is known regarding its effect and safety during pregnancy. Pregnant women prefer herbal medicine due to easy accessibility, traditional and cultural beliefs, and comparatively low cost. This study aimed to assess women’s knowledge and attitude towards the effects of herbal medicine usage during pregnancy and associated factors among women who gave birth in the last twelve months in Dega Damot district. Methods: A community-based cross-sectional study was conducted from January 1st to February 30th, 2021. A total of 872 women were selected using a stratified cluster sampling technique. Data were collected by face-to-face interviews using a structured, pretested, and interviewer-administered questionnaire. Data were entered into EPI data version 4.6 and exported to SPSS version 25 for analysis. Multivariable logistic regression was done and a p-value of ≤ 0.05 was used to declare the level of significance. Results: Women’s knowledge and positive attitude towards the effects of herbal medicine usage during pregnancy was 49.1% (95% CI: 46–52) and 57.3% (95% CI: 54–61), respectively. Access to media, had antenatal care visit, being urban dweller, history of herbal medicine usage, and a short distance to reach the nearby health facility were significantly associated with women’s knowledge about effects of herbal medicine usage. Besides, being primiparous and short traveling time to reach the nearby health facility was significantly associated with women’s attitude towards the effects of herbal medicine usage during pregnancy. Conclusion: Women’s knowledge and positive attitude towards the effects of herbal medicine usage during pregnancy was low. It is important to design strategies to improve the accessibilities of maternal health services, and expand access to media will have a great role in improving women’s knowledge and attitude towards herbal medicine usage during pregnancy.
A community-based cross-sectional study was carried out from January 1st to February 30th, 2021, in Dega Damot district, northwest Ethiopia. The district’s administrative town, Feres Bet, is located about 400 km northwest of Addis Ababa (the capital city of Ethiopia) and 117 km from Bahir Dar (the capital city of Amhara regional state). Based on the 2014 population projection by the Central Statistical Agency of Ethiopia, the district has a total population of 152,343; of whom, 77,338 were women.18 The district is administratively divided into 34 kebeles (the smallest administrative unit in Ethiopia), which are 2 urban and 32 rural kebeles. In addition, the district has one primary hospital, eight health centers, and thirty-two health posts. The overall antenatal care service utilization and institutional delivery in the district were 37.4% and 38.2%, respectively.19 All mothers who gave birth in the last twelve months and reside in the selected clusters of Dega Damot district during the data collection period were included. Mothers who were seriously ill and unable to communicate throughout the data collection period were excluded. The sample size for this study was determined by using a single population proportion formula by considering the following assumptions: 50% proportion of women’s knowledge and attitude towards the effects of HM usage during pregnancy (since there were no similar studies in Ethiopia), 95% level of confidence, and 5% margin of error. Where n = required sample size, z = standard normal distribution curve value for 95% confidence level = 1.96, = level of significance, p = proportion of women’s knowledge and attitude on effects of herbal medicine usage during pregnancy, and d = margin of error. By considering a design effect of 2 and a 10% non-response rate, the final sample size was 847. Dega Damot district has a total of 34 kebeles (2 urban and 32 rural). The kebeles were stratified into urban and rural. Nine kebeles (1 urban and 8 rural) were selected randomly. A house-to-house visit was conducted and all eligible women in the selected kebeles (clusters) were interviewed. A stratified cluster sampling technique was used to draw the final sample size. Finally, due to the effect of cluster sampling, a total of 872 women were interviewed. Herbal medicine usage: is the intake of any herb or herbal preparation (syrup, paste, and powder) during pregnancy either self-prescribed or recommended by family members, friends, herbalists, or others to manage any symptom, or perceived to support baby’s development.9 Adequate knowledge: Six questions were prepared to assess the knowledge of women about the effects of herbal medicine usage during pregnancy. Each yes or no question were coded into 1 and 0 respectively and for other questions with more than one possible answer, at least one correct answer was coded as 1. The minimum and maximum scores were 0 and 6, respectively. Thus, based on the variables set to assess knowledge of women on the effects of HM usage during pregnancy, women who scored above the mean (3.68) were considered as having adequate knowledge.20 Positive attitude towards the effects of HM usage during pregnancy: Eight questions were prepared to assess the attitude of women towards herbal medicine. Each question has a five-point Likert scale (1 = strongly disagree, 2 = disagree, 3 = neutral, 4 = agree, 5 = strongly agree). The total score was ranged from 8 to 40. Thus, based on the variables prepared to assess the attitude of women towards the effects of HM usage during pregnancy, women who scored above the mean (26.5) score were considered as having a positive attitude.20 Media exposure: Those who respond at least once a week for at least one of the media types (television, radio, or magazine) are considered to be regularly exposed.21 The data collection tool was developed by reviewing the literature.14,15,20,22–24 A structured, interviewer-administered questionnaire was used to collect the data through face-to-face interviews. Initially, the questionnaire was prepared in English and translated to the local (Amharic) language, and back to English to ensure consistency. The questionnaire comprises socio-demographic characteristics, reproductive and maternity healthcare characteristics, and knowledge and attitude-related questions. The study tool was assessed by a group of researchers to evaluate and enhance the items in the question. Four diploma and two BSc midwives were recruited for data collection and supervision, respectively. A pretest was done on 5% (43) of the calculated sample size outside of the study area. One-day training was given for data collectors and supervisors to assure language clarity and to give information on interview techniques, and how to keep the information. During the actual data collection period, the questionnaire was checked for completeness daily by the supervisors. The coded data were entered into EPI data version 4.6 and then exported to SPSS version 25 for cleaning and analysis purposes. The family wealth status was analyzed by using principal component analysis (PCA). Descriptive statistics were used to present the characteristics of the study participants. The binary logistic regression analysis was done to identify the factors associated with women’s knowledge and attitude towards HM usage during pregnancy. Variables having a p-value of ≤ 0.25 in the bivariable analysis were entered into a multivariable logistic regression analysis to identify independent factors associated with HM usage during pregnancy. The multicollinearity assumption was assessed using the variance inflation factor (VIF), in which VIF <10 were acceptable In the multivariable logistic regression, variables were selected in Backward Likelihood Ratio approach and a p-value of ≤ 0.05 with a 95% CI for the adjusted odds ratio was employed to ascertain the significant association. The study was conducted in accordance with the Ethiopian Health Research Ethics Guideline and the declaration of Helsinki. The ethical approval letter was obtained from the School of Midwifery, on behalf of the Institutional Review Board (IRB) of the University of Gondar. A formal letter of organizational approval was obtained from Dega Damot district health office. Afterward, the information regarding the purpose of the study and the rights of the participants was provided for the study participants. Finally, written informed consent was obtained from each participant before the actual data collection.
