Knowledge and menstrual hygiene practice among adolescent school girls in southern Ethiopia: a cross-sectional study.

backgroundMenstruation is a normal physiological process of females at their reproductive age. However, it is surrounded with social taboos and supernatural beliefs. The poor knowledge and understanding of menstruation may lead to unsafe hygienic practice that intern increases the risk of reproductive and genito-urinary tract infections, cervical cancer, school drop-out, poor academic performance and overall poor quality of life. Despite such clinical and academic effects, the knowledge and hygienic practice of adolescent girls towards menstruation is not well addressed in Ethiopia, particularly among school adolescent girls. Therefore, the main objective of this study was to assess the knowledge and menstrual hygiene practice among adolescent school girls in southern Ethiopia.

methodsThis was an institutional based cross-sectional study conducted at Gedeo zone high schools among 791 randomly selected adolescent girls using multi stage sampling technique. Data were collected using interviewer administered questionnaire. The collected data were entered to EPI-INFO (soft ware) and exported to SPSS version 20 for analysis. Bivariable and multivariable logistics analyses were computed to identify factors associated with the poor menstrual hygienic practice. During bi-variable analysis, variables with P-values of less than 0.25 were entered to multivariable model for further analysis. In the final model, P-value of less than 0.05 was used as a base to identify factors having a statistically significant association with poor menstrual hygiene practice at corresponding 95% confidence interval.

resultFrom a total of 791 adolescent girls participated in this study, 68.3% had poor knowledge of menstruation. About 48.1% of school girls used absorbent materials, and 69.5% clean their external genitalia. Generally, 60.3% of girls had poor menstrual hygienic practice. Age less than 15 years [OR = 1.71:95% CI (1.22, 2.39)], longer days of menstrual flow [OR = 2.51:95% CI (1.66, 3.80)] and poor knowledge of menses [OR = 1.48:95% CI (1.04, 2.1)] had a significantly associated with poor menstrual hygiene practice.

conclusionMajority of adolescent school girls had poor knowledge regarding menstruation and their hygienic practices are incorrect. This demonstrates a need to design acceptable awareness creation and advocacy programs to improve the knowledge and promote safe hygienic practice of adolescent school girls during menstruation.
