Prevalence and impact of dysmenorrhea in Swedish adolescents.

INTRODUCTION: The objective of this study was to estimate the prevalence of dysmenorrhea among adolescents and its effect on daily life.

MATERIAL AND METHODS: A web-based questionnaire with questions regarding menstrual symptoms was distributed to all girls born in 2000 and residing in Stockholm City (n = 3998). Questions regarding pain severity, other menstrual-related symptoms, medical treatment, healthcare visits, social and academic absenteeism were included in the questionnaire.

RESULTS: A total of 1785 (45%) young women responded to the questionnaire. Of these, 1580 (89%, 95% CI 87-90) stated that they had dysmenorrhea. Severe dysmenorrhea, scores 8-10 on the numeric rating scale for pain, was reported by 574 of 1580 women (36%, 95% CI 34-39). Fatigue was reported by 1314 of 1580 women (83%, 95% CI 81-85), headache by 1296 (82%, 95% CI; 80-84), dyschezia by 578 (37%, 95% CI 34-39) and dysuria by 560 (35%, 95% CI 33-38). A suboptimal use of analgesics was reported. Hormonal therapy as pain treatment was used by 10% (157/1580, 95% CI 9-12). Healthcare facilities, including school nurses, had been visited by 525 of 1580 women (33%, 95% CI; 31-36). Doctors had been consulted by 7% (116/1580, 95% CI 6-9). Fifty-nine percent (930/1580, 95% CI 56-61) reported refraining from social activities due to dysmenorrhea. Absenteeism from school was reported to occur monthly by 228 of 1580 women (14%, 95% CI 13-16), and several times per year by 716 (45%, 95% CI 43-48).

CONCLUSIONS: Our findings demonstrate that menstrual pain is prevalent among teenagers in Stockholm. The results indicate that many women are disabled in their daily life and that only a small number of women seek medical attention, although possible selection bias might have affected the results. Information and education are needed to optimize the use of existing treatment options and more awareness is needed to reduce normalization of disabling dysmenorrhea.
