Introduction – Menstruation is the most natural and physiological phenomenon which a female periodically goes through every month. Even today's era witnesses the association of the menstrual phenomenon with stigma and disgrace in several countries. The complete lack of knowledge about this subject which mostly ends up with the rise of myths and taboos in society is even worse. Adolescent girls must get to know about menstruation at an early stage while seeking education during schooling. This study highlights the level of knowledge, menstrual practices adopted and myths and taboos faced by adolescent girls of this area. Methodology - A cross-sectional study was undertaken among 115 school-going, adolescent girls. The adolescent girls being the respondents agreed to be part of the study and answered questions on the questionnaires which were provided to them. The main objective was to assess the knowledge about menstruation, menstrual hygiene, and the prevalence of various myths and taboos among school girls and their societies. Data analysis was done using SPSS 21.0 software and Chi-squared test with application of the Fisher exact test in few cases. Since 91 out of 115 girls responded, data analysis has been done accordingly for the number of girls who provided response. Results - Mean age of girls in this study was 13.75 ± 1.62. 64 (70.3%) and 27(29.6%) girls are menstruating and non-menstruating respectively. The most common response given by 43% of girls was that "periods come regularly every month once for 4 -5 days". Mothers in 66% of cases were the first informant about the phenomenon of menstruation followed by lady teachers at school. 73(80%) had prevalent myths and taboos related to menses which was required to be addressed. 47.2% of the girls were demonstrated by their teachers regarding the phenomenon of menstruation at school. Conclusion - Though many of the girls considered menstruation as a normal and physiological process majority were unaware of the uterus being the actual source of bleeding. Fortunately, teachers are acting as the first informant regarding the phenomenon of menstruation in this study for a high percentage of girls thereby addressing the associated myths and taboos related to the process. Gleefully the menstruating girls attended school regularly which is not affecting their education and learning thereby making them more self-reliant and help in overcoming societal issues and discrimination while addressing the menses process.
