Premenstrual Distress Among Japanese High School Students: Self-Care Strategies and Associated Physical and Psychosocial Factors.

This study aimed to identify self-care strategies and assess physical and psychosocial factors associated with premenstrual distress among high school students. A cross-sectional survey of 217 adolescent girls aged 15 to 18 years was conducted in October 2009. Most (84.3 percent) had at least one or more symptoms of premenstrual distress. Premenstrual distress interfered with normal school activity in 51.2 percent. Most participants (57.1 percent) did not perform any self-care strategies for premenstrual distress. A hierarchical multiple linear regression analysis was conducted. Comprehension of one's own physical and mental states during premenstrual phases mediated the relationship between neuroticism and premenstrual distress. Activity restrictions due to menstrual distress mediated the relationship between the family's understanding of one's behavior during premenstrual phases and premenstrual distress. Findings suggest that, even if girls have neuroticism, it will be important to teach them to address the comprehension of one's own physical and mental states so that perceptions of both premenstruation and menstruation become more positive. Findings also suggest that the family's understanding was associated with alleviation of premenstrual distress. This study suggests the need for education to help adolescent girls and their families manage premenstrual distress and increase awareness of the benefit of managing its associated symptoms.
