Stress Level with Menstrual Cycle in XI Class Girl Students at State Vocational High School

Abstract

This study discusses the relationship between stress levels and the menstrual cycle in 11th grade girls at SMK Negeri 1 Bagor Nganjuk. Stress is known to be one of the factors that cause disturbances in the menstrual cycle, as high cortisol hormone levels can affect the balance of reproductive hormones. This study uses a correlational design with a cross-sectional approach and was conducted on July 19, 2025. The population in this study consists of all 11th-grade female students totaling 232 individuals, with a sample size of 147 respondents selected using proportional random sampling technique. The independent variable in this study is the stress level measured by the DASS 42 questionnaire, while the dependent variable is the menstrual cycle measured by a specific menstrual cycle questionnaire. Data analysis is conducted using the Spearman-Rank Correlation statistical test with SPSS at a significance level of 0.05. The results of the study show that nearly half of the respondents experienced mild stress (34.7%), and from this group, 16.3% had menstrual cycles characterized by polymenorrhea. Statistical analysis showed a value of ρ = 0.00 < α = 0.05, which indicates a significant relationship between stress levels and menstrual cycles. The correlation coefficient value of r = 0.508 indicates that this relationship is in the moderately strong category. It is concluded that the higher the stress level, the greater the risk of disturbances in the menstrual cycle. Therefore, good stress management becomes an important effort in preventing menstrual irregularities.
