The change in appetite and food cravings before, during and after menstruation and the relationships between each premenstrual symptom and change in appetite and type of food with increased intake were investigated. This study was conducted by a self-administered questionnaire in 311 female students of health sciences. It was found that the proportion of students who increased the appetite was 70.4% during the menstruation cycle, and the highest period was before menstruation (85.8%). Sweets had the highest intake in all menstrual phases followed by junk food. It was found that increased appetite was significantly associated with depression and sleepiness. Moreover, increased intake of sweets was associated with depression, anger and sleepiness, while intake of junk food was associated with irritability and depression. In conclusion, the relationships between increased appetite for sweets and junk food and premenstrual symptoms indicate the need for promoting proper menstruation-related eating habits.
Mothers and family members of young female students play important roles for guiding their self-care strategies for menstruation-related symptoms; which often affect their daily life and academic life. The aim of this study is to clarify the differences in menstruation-related symptoms before and during menstruation in university students living alone and university students living with their family in Japan. We conducted a cross-sectional online survey to assess menstruation-related symptoms before and during menstruation using the menstrual distress questionnaire (MDQ). Among 135 students; the proportion of students living alone was 60.7% and the proportion of students living with their family was 39.3%. Before menstruation; the MDQ total score and the scores for negative affect and behavior change were significantly higher in students living alone than in students living with their family. During menstruation; scores for negative affect and impaired concentration were also significantly higher in students living alone. In addition; before menstruation; scores for an increase in appetite and craving for sweets were significantly higher in students living alone. Thus; living alone affected the psychological aspects of menstruation-related symptoms in young women. The results suggest that university students who live alone should be aware of the importance of talking about their menstruation problems with family members and seeking their advice
The coronavirus disease 2019 (COVID-19) pandemic affected the daily lifestyle of people, including many aspects affecting young women. Subsequent to the COVID-19 pandemic stress and anxiety have been reported related to menstrual disorders (Takmaz, Gundogmus, Okten, & Gunduz, 2021). The purpose of this study was to investigate the intensity and to compare menstruation-related symptoms before and during menstruation among university students in Japan. We conducted an online cross-sectional study from May to July 2021 using a menstrual distress questionnaire (MDQ) to assess symptoms experienced before and during menstruation. Our results showed that of 141 students, five students (3.5%) did not report any symptoms before menstruation and one student (0.7%) had no symptoms during menstruation. We found that the most frequently experienced symptoms before menstruation were skin blemishes or disorder, mood swings, irritability, swelling, cramps, fatigue, take naps, stay in bed, feeling sad or blue, weight gain and difficulty concentrating. The most frequently experienced symptoms during menstruation were cramps, fatigue, irritability, mood swings, take naps, stay in bed, feeling sad or blue, backache, swelling, skin blemish or disorder, and poor school/work performance. The total MDQ score was significantly higher during menstruation than before menstruation. Among the MDQ eight scales, the scores of five scales including pain, autonomic reaction, impaired concentration, behavior change, and control were significantly higher during menstruation than before menstruation. The prevalence of increased appetite and craving for sweets were higher than MDQ symptoms before menstruation. The prolonged exposure to pandemic may have more effect on psychological symptoms than on physical symptoms.
Introduction: Some somatic and psychological disorders have been associated with handgrip strength, which is an easy, inexpensive and noninvasive method for assessment of muscle strength. We conducted a cross-sectional study to clarify the relationship of handgrip strength and menstruation-related symptoms. Material and Methods: Handgrip strength was measured and a self-administered questionnaire was performed in female university students in Japan. Results: Handgrip strength did not significantly differ among the menstrual phases. The mean handgrip strength level (n = 260) was 26.0 ± 3.9 kg. We divided the subjects into three groups according to the handgrip strength level. Handgrip strength was associated with degrees of depression and anxiety during menstruation. Conclusion: This can be used as fundamental data in further clarifying the relationship between muscle strength and menstruation-related symptoms.
Smartphones use for a long period of time can cause health problems including physical condition, psychological condition and sleeping status. In addition, smartphones use may affect menstruation related symptoms. This study was conducted using a self-administered questionnaire between June and November in 2016 to clarify the differences in physical and psychological condition, sleeping status and menstruation-related symptoms before and after starting to use smartphones in female university students in Japan. We recruited 273 female nursing students and the response rate was 95.2%. We found significant changes after starting to use smartphones regarding eyestrain (p < 0.001), posture (p = 0.002), stiffness of neck, back and shoulders (p < 0.001), level of outdoor activity (p < 0.001), difficulty concentrating (p < 0.001), lack of motivation (p < 0.001), and sensitivity to stress (p = 0.005). Moreover, we also found that fatigue before menstruation and headache/low back pain during menstruation were higher after starting to use smartphones. The proportions of students with irritability and depressive feeling as emotional premenstrual symptoms appeared higher after starting to use smartphones. These results imply that young women should refrain from using smartphones if they have visual display terminal-related symptoms, disturbance of sleep pattern and menstruation-related symptoms before and during menstruation.
The aim of this study was to clarify how male rotating night shift workers cope with male climacteric symptoms and whether coping strategies are different depending on age. A self-administered questionnaire survey regarding coping strategies in male rotating night shift workers over the age of 20 years was performed. Male climacteric symptoms were evaluated by using the Aging Male’s Symptoms scale [AMS]. Of 1,891 questionnaires that were sent, 1,561 were collected. For all of the 16 symptoms, the most frequent strategy was to try to ignore and tolerate the symptoms and the second-most frequent strategy was to take time to relax. The proportions of men who ignored and tolerated psychological symptoms and sleep problems were high in all age groups. The proportions of men who ignored and tolerated the symptom of decline in the feeling of general well-being were high in men in their 20s and low in men in their 60s. The proportion of men who consulted a doctor for the symptom of joint and muscular pain was high in men in their 50s. The most frequent strategy for coping with male climacteric symptoms was to ignore and tolerate the symptoms and the second-most frequent strategy was to take time to relax. There was a difference in coping behavior depending on age in rotating night shift workers.
Sensitivity to cold, which is a popular symptom in Japanese women, is associated with various symptoms such as shoulder stiffness and general fatigue. However, an association of sensitivity to cold with muscle strength has not been reported. The aim of the study was to clarify the associations of sensitivity to cold with handgrip strength and with menstruation-related symptoms in female university students in Japan. We recruited 278 female university students in Japan. Sensitivity to cold and menstruation-related symptoms including physical and psychological symptoms were assessed by using a self-administered questionnaire that we designed. Handgrip strength was measured by using a handgrip strength dynamometer. We received responses from 269 students. The prevalence rate of sensitivity to cold in the subjects was 54.3%. The students who had sensitivity to cold had a lower handgrip strength level (25.5 ± 3.8 kg) than did the students who did not have sensitivity to cold (26.7 ± 3.9 kg) (p = 0.017). Sensitivity to cold was associated with low body mass index. In addition, the students who had sensitivity to cold tended to have low back pain and constipation during menstruation. In conclusion, sensitivity to cold is an important symptom associated with muscle strength as well as menstruation-related symptoms for young women.
