The prevalence of moderate-severe premenstrual syndrome and premenstrual dysphoric disorder and the related factors in high school students: A cross-sectional study.

OBJECTIVE: Premenstrual syndrome (PMS) is a clinical condition with physical and psychological symptoms affecting female students' quality of life, social activity, and school performance. Since most studies have focused on adult women, this study aimed to evaluate the prevalence of moderate-severe PMS, premenstrual dysphoric disorder (PMDD), and their related factors in high school students. METHODS: The participants of this cross-sectional study, conducted in 2019, were 900 high school students in Sari, north of Iran. They were selected by census method from six high schools. Data were collected using Premenstrual Syndrome Screening Tool and General Health Questionnaire. RESULTS: The prevalence of moderate-severe PMS and PMDD were 33.9% and 12.3%, respectively. According to the logistic regression model, dysmenorrhea was significantly associated with a higher prevalence of moderate-severe PMS [adjusted odds ratio (AOR) 2.356, confidence interval (CI): 1.706-3.254, p < 0.0001] and PMDD (AOR: 1.924, CI: 1.186-3.120, p = 0.0008). Moreover, optimal general health was associated with a lower prevalence of moderate-severe PMS (AOR: 0.326, CI: 0.221-0.480, p < 0.0001) and PMDD (AOR: 0.309, CI: 0.161-0.593, p < 0.0001). The findings revealed that a family history of PMS and adding excess salt to the food were associated with a higher prevalence of PMDD (p < 0.05). CONCLUSION: Although many high school students do not meet the criteria for PMDD, many experience PMS, which could be diminished with proper diet and improved general health.

The effect of peer education compared to education provided by healthcare providers on premenstrual syndrome in high school students: A social network-based quasi-experimental controlled trial.

AIM: This study aimed to compare the effect of peer education and education provided by healthcare providers on PMS in high school students. MATERIALS AND METHODS: This quasi-experimental non-randomized controlled trial with a three-armed parallel design was performed on 90 students allocated in three groups, namely, education by peer (intervention group 1 = 30), education by a healthcare provider (intervention group 2 = 30), and a control group (n = 30). The primary outcome was a change in the score of PMS, and the secondary outcomes were changes in the general health score and the frequency of premenstrual dysphoric disorder (PMDD). Education about PMS management was held in WhatsApp messenger in six sessions (two sessions per week) for both intervention groups. All three groups received routine school counseling. The researchers applied repeated-measures ANCOVA, McNemar, and post-hoc Bonferroni tests. RESULTS: Education in intervention group 1 (Partial Eta Squared = 0.67, p < 0.0001) and intervention group 2 (Partial Eta Squared = 0.82, p < 0.0001) significantly reduced the PMS score compared to the control group. In addition, the change in general health score in the intervention groups compared to the control group showed the effectiveness of the intervention (p < 0.001). Education did not significantly reduce PMDD frequency in the intervention groups compared to the control group (p > 0.05). CONCLUSION: This study suggests education by peers and healthcare providers effects on PMS and general health in adolescents. It suggested that the effectiveness of these approaches be investigated in other adolescents' health conditions.

A comparison between the effects of school-based education programs provided by peer group versus health practitioners on premenstrual syndrome in adolescents: A protocol for a non-masked clinical trial.

AIM: To compare the effect of school-based education programs, by peer group versus health practitioner on Premenstrual Syndrome (PMS) in adolescent girls. DESIGN: Non-masked three-armed clinical trial. METHODS: Ninety 11th-grade students with moderate to severe PMS will be allocated to Intervention Group 1 (IG1), Intervention Group 2 (IG2) and Comparison Group (CG). Three weeks (six online sessions) of parallel education will be implemented in IG1 by trained peer educators and in IG2 by a health practitioner. The primary outcome will be changes in PMS severity score between three groups over time (measured by Daily Record of Severity of Problems). Secondary outcomes include changes in Premenstrual Dysphoric Disorder and General Health. Data collection will be conducted in two-time points, at baseline, and at the end of the intervention. RESULTS: Our study will explore the effect of school-based education programs, by peer group versus health practitioner on PMS. This will add to the evidence-based interventions to PMS management and the effectiveness of peer education in health promotion of adolescents girls.
