Dysmenorrhea is a health problem that has a negative impact on the physical and emotional aspects of health. It also causes absenteeism in school that affects academic performance. The aim of this study was to analyse the influence of macronutrient intake, stress, and prostaglandin levels (pgf2α) on adolescent dysmenorrhea incidence. This study is an observational cohort study of 16 years old adolescents with a menstrual cycle every 21–35 days and a menstrual period of about 5–7 days. Results show that: - levels of pgf2α affect the incidence of dysmenorrhea i.e., prostaglandins can reduce or temporarily inhibit blood supply to the uterus, causing the uterus to lack oxygen and cause myometrium contraction which in turn causes pain. - stress is very influential with dysmenorrhea as it can interfere with the work of the endocrine system. - an insufficient intake of nutrients may increase the risk of dysmenorrhoea. Thus, adolescents should ensure adequate intake of macronutrients especially during menstruation. Authors conclude that stress and prostaglandin levels significantly affect the occurrence of dysmenorrhea in adolescents.
Abstract
OBJECTIVES This study aimed to analyze the influence of macronutrient intake, stress, and prostaglandin levels (pgf2α) on adolescent dysmenorrhea incidence. METHOD This type of study is observational analytic with a cohort study draft done in January-March 2020 at High junior school 21 Makassar. Respondents in this study were grade X and XI students divided into 64 teenagers who had dysmenorrhea and 64 adolescents who did not experience Dysmenrhea. The criteria of the respondent in this study were the reproductive age, already experiencing menstruation, knowing the time and date of menstruation, menstrual cycles were regular, and willing to be respondents. The study used Menstrual Symptoms Questionnaire (MSQ) and used an ultrasonography (ultrasound) examination to perform the sample cervical. Food recall 24 hours to assess the intake of macronutrients, Depression Anxiety Stress Scales (DASS 42) to measure stress levels, and an examination of urine prostaglandin levels using the method Enzyme-Linked Immunosorbent Assay (ELISA). Urine intake is carried out on the second day as much as 2-5cc. Data were analyzed by the Chi-square test and logistics regression backward. RESULT A multivariate analysis showed a variable that strongly affects dysmenorrhea is stress with the value p=0.000 and the level of prostaglandins with p-value=0.003 compared to other variables. CONCLUSION Stress and prostaglandin levels significantly affect the occurrence of dysmenorrhea in adolescents.

Plain language summary
Alterations in normal cortisol patterns have been observed in people who are obese. The effect of weight loss on cortisol levels, a measure of hypothalamic pituitary adrenal (HPA) activity, in overweight individuals is not known. The aim of this study was to test the hypothesis that 6 months of moderate caloric restriction would alter morning and diurnal salivary cortisol levels. Thirty-five overweight adults (average BMI 27.8 kg/m2) took part in this randomised control trial. Participants were assigned to either calorie restriction (CR: 25% reduction in energy intake), calorie restriction+exercise (CR+EX: 12.5% reduction in energy intake+12.5% increase in exercise energy expenditure) or control (healthy weight-maintenance diet) for 6 months. Salivary cortisol was measured at 8:00, 8:30, 11:00, 11:30, 12:30, 13:00, 16:00 and 16:30. Morning cortisol was defined as the mean cortisol concentration at 08:00 and 08:30. Diurnal cortisol was calculated as the mean of the 8 cortisol measures across the day. Across all groups, higher morning and diurnal cortisol levels were associated with impaired insulin sensitivity. There was no significant effect of group, time or sex on morning or diurnal cortisol levels. The authors concluded that a 10% weight loss with a 25% CR diet alone or with exercise did not impact morning or diurnal salivary cortisol levels in overweight individuals. Their findings suggest that prolonged restriction of energy intake is not perceived by the body as a stressor, and therefore CR may present a viable intervention.
Abstract
OBJECTIVE The effect of weight loss by diet or diet and exercise on salivary cortisol levels, a measure of hypothalamic pituitary adrenal activity, in overweight individuals is not known. The objective was to test the hypothesis that 24 weeks of moderate caloric restriction (CR) (25%) by diet or diet and aerobic exercise would alter morning and diurnal salivary cortisol levels. DESIGN AND SETTING Randomized control trial in an institutional research center. PARTICIPANTS Thirty-five overweight (BMI: 27.8±0.7 kg/m(2)) but otherwise healthy participants (16 M/19 F). INTERVENTION Participants were randomized to either calorie restriction (CR: 25% reduction in energy intake, n=12), calorie restriction+exercise (CR+EX: 12.5% reduction in energy intake+12.5% increase in exercise energy expenditure, n=12) or control (healthy weight-maintenance diet, n=11) for 6 months. MAIN OUTCOME MEASURE Salivary cortisol measured at 8:00, 8:30, 11:00, 11:30, 12:30, 13:00, 16:00 and 16:30. Morning cortisol was defined as the mean cortisol concentration at 08:00 and 08:30. Diurnal cortisol was calculated as the mean of the 8 cortisol measures across the day. RESULTS In the whole cohort, higher morning and diurnal cortisol levels were associated with impaired insulin sensitivity (morning: P=0.004, r(2)=0.24; diurnal: P=0.02, r(2)=0.15). Using mixed model analysis, there was no significant effect of group, time or sex on morning or diurnal cortisol levels. CONCLUSION A 10% weight loss with a 25% CR diet alone or with exercise did not impact morning or diurnal salivary cortisol levels.
