Objective: In this study, we present the results of bio-demographic characteristics of households and associated factors with Down syndrome (DS) birth in Morocco.
Methods: We conducted a retrospective survey between 2014 and 2017 addressed to 277 families with 925 siblings and at least one child with DS (279 with DS). The data are collected using a standardized questionnaire in Marrakech-Safi region. Data were entered and analyzed using the statistical program SPSS statistics software for Windows (version 20.0). Chi-square (χ2) and student t tests were used for testing statistical significance. Differences were considered significant when the p-value <0.05.
Results: The binary logistic regression analysis between DS and non-DS children in their bio-demographic characteristics studied (sex, breastfeeding, duration of exclusive breastfeeding, birth weight, maternal age at birth, paternal age at birth, oral contraceptive use, duration of oral contraceptive use before pregnancy, child age and rank of birth) showed that only maternal age and paternal age at birth, duration of exclusive breastfeeding, birth weight and child age (OR= 1.08; 95%Cl: 1.04-1.13, OR= 1.04; 95%Cl: 1.00-1.08, OR= 0.95; 95%Cl: 0.92-0.98, OR= 0.31; 95%Cl: 0.22-0.44 and OR= 0.90; 95%Cl: 0.87-0.93, respectively). In the other hand, the comparison between some of socio and bio-demographic characteristics of households studied with data from National Population Survey and Family health (2018) showed a higher level of education in women and men in our sample. Similar results were shown in proportion of men and women in paid employment, the proportion of smoking and alcohol consumption among men and the rate of oral contraceptive use before pregnancy among women.
Conclusion: Highlighting the bio-demographic characteristics of people with DS will help families to take good care of this group. .
