“…Smoking and alcohol consumption were not analyzed as covariates possibly associated with dysmenorrhea, although previous studies have suggested this association [15,24]. Parity of the participant was not analyzed in this study; a recent survey in Japan suggested that increasing parity was associated with decreasing prevalence of dysmenorrhea [18]. Finally, this study was limited to 1 month; thus, it was not possible to analyze whether the participants visited physicians for dysmenorrhea or missed menstruation at times outside the limits of this study period.…”

“…The lower incidence of dysmenorrhea in the present study could be explained by the 1‐month study period. Indeed, a recent preliminary survey in Japan indicated more than 70% of Japanese women suffered from dysmenorrhea during 6 months of retrospective recall [18]. Alternatively, Japanese women may not recognize mild menstrual pain events as serious enough to record in a health diary.…”

“…A number of studies have targeted young women, including older adolescents (i.e., high school students), as well as older women, but only a few studies have targeted younger adolescents, i.e., junior high school students (aged 12-15 years) (Ju et al 2014). Although a nationwide survey of dysmenorrhea was previously conducted in Japan, the survey did not report on the prevalence of dysmenorrhea among teenagers (Osuga et al 2005). Age at menarche has been decreasing over the last several decades, and the current mean menarcheal age in Japan is 12.2 years (Hinobayashi 2010).…”

Dysmenorrhea is a common menstrual disorder experienced by adolescents, and its major symptoms, including pain, adversely affect daily life and school performance. However, little epidemiologic evidence on dysmenorrhea in Japanese adolescents exists. This cross-sectional study aimed to determine the prevalence of and identify factors associated with dysmenorrhea in Japanese female junior high school students. Among 1,167 girls aged between 12 and 15 years, 1,018 participants completed a questionnaire that solicited information on age at menarche, menstruation, and lifestyle, as well as demographic characteristics. Dysmenorrhea was defined based on menstrual pain using a Visual Analog Scale (VAS), with moderate or severe (moderate-severe) dysmenorrhea, which adversely affects daily life, defined as VAS ≥ 4, and severe dysmenorrhea defined as VAS ≥ 7. The prevalence of moderate-severe dysmenorrhea was 476/1,018 (46.8%), and that of severe dysmenorrhea was 180/1,018 (17.7%). Higher chronological and gynecological ages (years after menarche) were significantly associated with a higher prevalence of dysmenorrhea regardless of severity (P for trend < 0.001). In addition, short sleeping hours (< 6/day) were associated with moderate-severe dysmenorrhea (OR = 3.05, 95%CI: 1.06-8.77), and sports activity levels were associated with severe dysmenorrhea (P for trend = 0.045). Our findings suggest that dysmenorrhea that adversely affects daily activities is highly prevalent, and may be associated with certain lifestyle factors in junior high school students. Health education teachers should be made aware of these facts, and appropriately care for those suffering from dysmenorrhea symptoms, absentees, and those experiencing difficulties in school life due to dysmenorrhea symptoms.

“…Childbirth decreases the likelihood of dysmenorrhea because of the reduced number of adrenergic receptors in the uterus [4-11]. Dysmenorrhea is the leading cause of absence from school and work and has a negative impact on the quality of life and general health of women [8,12-14].…”

Comparing the analgesic effect of heat patch containing iron chip and ibuprofen for primary dysmenorrhea: a randomized controlled trial

et al. 2012

BackgroundPrimary dysmenorrhea is a common and sometimes disabling condition. In recent years, some studies aimed to improve the treatment of dysmenorrhea, and therefore, introduced several therapeutic measures. This study was designed to compare the analgesic effect of iron chip containing heat wrap with ibuprofen for the treatment of primary dysmenorrhea.MethodsIn this randomized (IRCT201107187038N2) controlled trial, 147 students (18–30 years old) with the diagnosis of primary dysmenorrhea were enrolled considering the CONSORT guideline. Screening for primary dysmenorrhea was done by a two-question screening tool. The participants were randomly assigned into one of the intervention groups (heat Patch and ibuprofen). Data regarding the severity and emotional impact of the pain were recorded by a shortened version of McGill Pain Questionnaire (SF-MPQ). Student's t test was used for statistical analysis.ResultsThe maximum and minimum pain severities were observed at 2 and 24 hours in both groups. The severity of sensual pain at 8, 12, and 24 hours was non-significantly less in the heat Patch group. There was also no significant difference between the groups regarding the emotional impact of pain at the first 2, 4, 8, 12 and 12 hours of menstruation.ConclusionsHeat patch containing Iron chip has comparable analgesic effects to ibuprofen and can possibly be used for primary dysmenorrhea.Trial registrationIRCT201107187038N2
