Insufficient food intake can interfere with the duration of menstruation</em>.<em> </em><em></em></p><p><strong><em>Objectives:</em></strong><em> To analyse the relationship between the intakes of vitamin D and zinc and the menstrual periods of the adolescent girls.</em></p><p><strong><em>Methods:</em></strong><em> A total of 154 tenth- and eleventh-grade girl students from two senior high schools in Sukoharjo Regency, Central Java participated in this cross-sectional study. They were chosen using purposive-sampling technique with the following inclusion criteria: age of 15-18 years and not menstruating. The anthropometric data were collected by the measurement of Body Weight(kg) and Body Height (m) while the data of vitamin D and zinc intakes were obtained using a 24-hour-food-recall questionnaire in 3 alternating days. Chi-square test and multiple logistic regression were used to analyse the research variables with the significance value of &lt; 0.05. </em></p><p><strong><em>Results</em></strong><em>: All adolescent girls had inadequate vitamin D intake and 89% of them had inadequate zinc intake. Long menstrual duration occurred in 8.4% of the adolescent girls. The deficient intake of vitamin D (OR = 4.57. 95% CI = 0.943-22.154; p = 0.059) lengthened the menstrual period whereas deficient zinc intake, (OR = 0.247. 95% CI = 0.073-0.835; p = 0.024) shortened it compared with adequate vitamin D and zinc intakes in adolescent girls.</em></p><p><strong><em>Conclusions:</em></strong><em> The deficient intake of vitamin D increases the menstrual duration, but the deficient intake of zinc actually lowers the menstrual period of high-school girls in Sukoharjo Regency. Nutritional education is needed to increase micro-nutrient intakes to maintain menstrual duration.</em></p><p> </p><p><strong>KEYWORDS:</strong><em> adolescent girls, menstruation, vitamin D intake, zinc intake.</em></p><p><strong> </strong></p>
