Status Gizi dan Siklus Menstruasi Pada Remaja Putri

Background: Nutritional status is an important aspect of adolescent girls' health that may be associated with reproductive function and menstrual cycle regularity. Nutritional imbalance, including both undernutrition and overnutrition, may theoretically affect hormonal balance involved in the menstrual cycle. Objectives: This study aimed to analyze the relationship between nutritional status and menstrual cycle among adolescent girls at SMA YAPIM MEREK. Methods: This study employed a quantitative analytical approach with a cross-sectional design. The study was conducted in 2026 with a total of 93 adolescent girls selected using total sampling. Nutritional status was determined based on Body Mass Index (BMI), while menstrual cycle data were collected using a questionnaire and categorized as normal or abnormal. Data were analyzed using univariate and bivariate analyses, with Fisher's Exact Test applied to examine the relationship between nutritional status and menstrual cycle at a significance level of α=0.05. Results: The results showed that most respondents had normal nutritional status, with 71 respondents (76.3%), while 22 respondents (23.7%) had abnormal nutritional status. A total of 76 respondents (81.7%) experienced abnormal menstrual cycles, while 17 respondents (18.3%) had normal menstrual cycles. The Fisher's Exact Test resulted in a p-value of 0.539 (p>0.05), indicating that there was no significant relationship between nutritional status and menstrual cycle. The Contingency Coefficient of 0.064 indicated a very weak relationship between the two variables. Conclusions: Nutritional status was not significantly associated with menstrual cycle among adolescent girls at SMA YAPIM MEREK. Menstrual cycle regularity may be influenced by other factors, including psychological stress, physical activity, sleep patterns, dietary patterns, age at menarche, and hormonal factors.
