<![CDATA[In adolescent females, menarche signifies the onset of the reproductive phase, frequently accompanied by health complications, one of which is dysmenorrhea—menstrual pain that disrupts daily activities. Data indicates that dysmenorrhea impacts over 60% of adolescent girls in Indonesia, with factors such as stress and dietary choices involving fast food believed to significantly influence pain intensity. At Public Middle School 02 in Bengkulu City, a similar occurrence was seen, with numerous female students reporting dysmenorrhea-related disorders that impeded their concentration and participation in school activities. The objective of the study was to ascertain the correlation between stress levels, fast food consumption patterns, and the prevalence of dysmenorrhea among teenage girls at Public Middle School 02 in Bengkulu City. This study employed a case-control design to compare case and control groups, aiming to elucidate the association between stress levels and fast food eating behaviours concerning the occurrence of dysmenorrhea in teenage females at Public Middle School 02 in Bengkulu City. The study comprised 31 case girls with obesity and 31 control girls without obesity, randomly recruited by simple random sampling. Data were gathered through questionnaires to assess stress levels, fast food consumption behaviours, and the prevalence of dysmenorrhea, which were subsequently analysed univariately and bivariately using statistical methods, including normality tests, homogeneity tests, and logistic regression, to ascertain the significant relationships among these variables. This study's results indicated a correlation between fast food eating behaviour, stress levels, and the prevalence of dysmenorrhea among adolescent girls at Public Middle School 02 in Bengkulu City. The normality test demonstrated that both variables exhibited a normal distribution, satisfying the criteria for parametric analysis. Univariate analysis indicated that the majority of respondents in the case group reported dysmenorrhea, with many exhibiting moderate stress levels and moderate fast food consumption patterns. Bivariate tests employing odds ratio analysis revealed that intermediate stress levels were significantly associated with the occurrence of dysmenorrhoea with OR:19.1, 95%CI 2.9-199.7, dan p-value: 0.000, exhibiting odds 19.1 times greater than those associated with mild stress, although fast food intake shown no significant association with dysmenorrhoea. The results indicate that stress has a more significant impact on the occurrence of dysmenorrhea than fast-food consuming habits. The personnel and educators in a public middle school in Bengkulu City must cultivate a school environment that is more conducive to reproductive health, emotional wellness, and nutritious eating practices for female pupils.]]>
