Characteristics of Menarcheal Age, Menstrual Hygiene and Socio-Demographic Factors in Girls with Down Syndrome in Morocco.

The purpose of this study was to determine the characteristics of menarcheal age, menstrual hygiene and their associated socio-demographic factors in girls with Down syndrome (DS) in Morocco. An analytical cross-sectional study was conducted between May 2014 and November 2017, including 59 parents/guardians of girls with Down syndrome aged 9-32 years. Data were collected through a standardized questionnaire providing information about socio-demographic and cultural conditions of parents, nutritional status and some functional abilities of girls. The median age at menarche was estimated using retrospective and status-quo methods, respectively. Data were entered and analyzed using the statistical program SPSS statistics software for Windows (version 20.0). Chi-square (χ2) and Mann-Whitney tests were used for testing statistical significance. The age at menarche ranged from 9 to 16 years old. The median was 13.0 (IQR, 11.0-14.0) years. The median age of menarche by probit analysis was 12.55 years. The relationship between menarcheal age, menstrual hygiene and the selected parameters showed a significant difference in age at menarche only regarding the parameter of number of siblings (Z = 2.14; p = .03), and in menstrual hygiene regarding mother's level of education, family size and age of talking (χ2 = 5.04, p = .02; χ2 = 3.75, p = .05 and χ2 = 4.99, p = .02, respectively). Most girls with DS attain menarche at the usual age as their counterparts in the general population and do not have enough knowledge about menstruation. Mobilization of all interventionists is urgent to develop adolescent skills about practices related to menstruation and menstrual hygiene.
