Association among dysmenorrhea and activity limitation and participation restrictions in adult women: a cross-sectional study, Brazil -2017.

Background: The present study aims to analyse if dysmenorrhea is associated with activity limitations and participation restrictions in experencied by adult women.

Methods: This is a cross-sectional study carried out with adult women recruited from primary health services in Brazil between 2016 and 2017. Dysmenorrhea was measured via a self-report and the activity limitation and participation restrictions was assessed by the World Health Disability Assessment Schedule (WHODAS2.0). Pain and level of physical activity were assessed, respectively, by the numerical pain rating scale and International Physical Activity Questionnaire (IPAQ), short version. Associations between groups, dysmenorrhea and without dysmenorrhea (WD), were analysed by the median difference, Mann Whitney test, effect size measures and 95 % confidence interval. Statistical significance was p <0.05.

Results: The prevalence of dysmenorrhea was 54 %. The pain lasted an average of three days or more (66 %). The average pain intensity, in the crisis period, was 6.1 ± 2.6, women who presented severe pain complaints were associated with considerable difficulties in their domains of mobility (p = 0.003; 2 = 0.115), participation (p = 0.030; 2 = 0.063) and total score (p = 0.012; 2 = 0.086), with a moderate effect size for all variables.

Conclusions: Severe dysmenorrhea was associated with higher scores of disabilities assessed by the WHODAS 2.0, especially in mobility, and participation domains.
