Various factors, including psychological stress, nutritional status, and sleep quality, have been reported to Influence the regularity of the menstrual cycle. this studi to analize the relationship between stress levels, nutritional status, and sleep quality with menstrual cycle regularity in adolescents. The results. The study showed that 40% of respondents experienced irregular menstrual cycles. Stress was significantly associated with menstrual irregularity . =0. , adolescents with high stress were 3. 1 times more likely to have irregular cycles. Poor nutrition was also correlated . =0. , with undernourished adolescents being 2. 4 times more likely to experience irregular cycles. Poor sleep quality had a significant relationship as well . =0. , with poor sleepers being 2. 9 times more likely to have irregular cycles. This study concludes that stress, nutritional status, and sleep quality are significantly associated with menstrual cycle regularity in adolescents, with stress being the most dominant factor. Adolescents with high stress, malnutrition, and poor sleep are at higher risk of menstrual cycle irregularity. It is recommended that adolescents maintain reproductive health through stress management, a balanced diet, and good sleep Health workers and schools need to provide education and support to help adolescents maintain menstrual cycle regularity.

Stress Journal for Quality in Women's Health | 135 Journal for Quality in Women's Health INTRODUCTION Adolescence is a crucial period of human development characterized by psychosocial changes. One of the most development in females is the establishment of a regular menstrual cycle, which reflects the maturity and balance of the reproductive system. regular menstrual cycle is considered a vital sign of reproductive health, while irregular cycles may indicate underlying health or lifestyle problems (WHO. Menstrual cycle irregularities are commonly experienced by adolescents, ranging from delayed menarche, oligomenorrhea, polymenorrhea, to The prevalence of adolescents is reported to be between 30Ae 50% in various countries, indicating a significant public health issue (Harlow & Campbell, 2. These irregularities may not only affect reproductive health but also the psychological well-being Several factors are believed to influence menstrual cycle regularity. Stress is one of the most frequently reported psychological contributors, as it interferes with the hypothalamicpituitary-ovarian (HPO) axis and Adolescents often face academic pressure, social challenges, and familyrelated stress, all of which may impact their menstrual health. Nutritional status is another undernutrition and overnutrition can alter the secretion of reproductive hormones, leading to irregular ovulation and menstrual disturbances. Sleep quality also plays a significant role, as inadequate or poor-quality sleep can disrupt circadian rhythms and hormonal balance, particularly melatonin and gonadotropins, which are crucial for menstrual regulation (Kumar et al. Previous studies have shown similar associations. Raval et al. reported that high stress was strongly linked to irregular menstrual cycles among Indian adolescents. Li et al. demonstrated a significant relationship between poor sleep patterns and menstrual disturbances in Chinese Frisch . highlighted that undernutrition and low body fat percentage can lead to hypothalamic These findings confirm the multifactorial nature of menstrual however, most of the Indonesia, and very few integrated the three factorsAistress, nutrition, and sleep qualityAitogether in one analysis. Indonesia, reproductive health issues remain a Many menstruation and its determinants, while lifestyle patterns such as poor diet, irregular sleep, and high stress levels are increasingly prevalent. Despite its importance, menstrual health has often been overlooked in adolescent health programs, which tend to focus more on early marriage, pregnancy prevention. Therefore, investigating lifestyle-related factors such as stress, nutrition, and sleep quality in relation to menstrual cycle regularity is highly relevant for developing comprehensive adolescent health strategies. This study aimed to analyze the association between stress. Journal for Quality in Women's Health | 136 Journal for Quality in Women's Health nutritional status, and sleep quality with 3.
