Latar Belakang Riset yang telah dilakukan pada tahun 2016 melaporkan bahwa di Indonesia sendiri diperkirakan sebesar 64,25% yang terdiri dari 54,89% dismenore primer dan 9,36% dismenore sekunder. Dismenore juga dilaporkan sebagai penyebab utama absenteisme sekolah pada remaja perempuan. Faktor-faktor risiko yang dapat meningkatkan kejadian dismenore terdiri dari banyak hal dan salah satu faktor yang masih kontroversial yakni produk susu. Produk susu telah dilaporkan dapat meningkatkan kejadian dismenore karena mengandung A1 caesin, yaitu salah satu produk yang dapat menyebabkan inflamasi, tetapi ada beberapa riset yang juga menunjukkan bahwa produk susu dapat mengurangi ketingkatan terjadinya dismenore dengan cara menurunkan eksatibilitas otot-otot uterus.

Pengambilan sampel dilakukan dengan teknik sistem acak sederhana. Hasil Analisis Data: Penelitian ini menunjukkan hubungan yang tidak bermakna antara produk susu dan tingkat kejadian dismenore primer (p-value = 0,710) dan produk susu dan nyeri dismenore primer (p-value = 0,288). Kesimpulan: Tidak terdapat hubungan yang bermakna antara produk susu dan tingkat kejadian dismenore pada mahasiswi Fakultas Kedokteran Universitas Pelita Harapan Kata kunci: Dismenore, Produk susu, Mahasiswi Fakultas Kedokteran Universitas Pelita Harapan / ABSTRACT Lourdes Joanna Kusumadi (01071180126) CORRELATION BETWEEN DAIRY PRODUCTS AND PRIMARY DYSMENORRHEA ON FEMALE UNIVERSITY STUDENTS AT THE SCHOOL OF MEDICINE IN PELITA HARAPAN UNIVERSITY Background Research carried out in 2016 reported dysmenorrhea incidence in Indonesia alone was estimated at 64.25%, consisting of 54.89% primary dysmenorrhea and 9.36% secondary dysmenorrhea. Dysmenorrhea is also reported to be one of the main cause of school absenteeism among girls. As many as 14% to 52% of school absences among adolescent girls in the United States are due to dysmenorrhea. Meanwhile, in Australia 53% have reported limitations in school activities such as sports and social activities due to dysmenorrhea. There are many risk factors that can increase the likelihood of dysmenorrhea, and one of the factor that has still remain controversial is the consumption of dairy products.

However, there are still some research that also shows that dairy products can reduce the incidence of dysmenorrhea by decrease the contraction on the uterine muscles. Purpose The purpose of this study is to find the relationship between Dairy Products and The Incidence Rate of Dysmenorrhea on Female University Students at School of Medicine in Pelita Harapan University. Hypothesis There is a correlation between dairy products and the incidence rate of dysmenorrhea in female university students at School of medicine in Pelita Harapan University. Methodology The study will be done with an unpaired categorical comparative analysis with cross-sectional method, and this research will take place between January to March 2021, with the target population of 76 female university students at School of Medicine in Pelita Harapan University that fulfills the criteria. Sample will be taken with convenience sampling method. Results: This study does not show significant correlation between dairy product and primary dysmenorrhea (p-value = 0,710) and between dairy products and pain intensity (p-value = 0,288) Conclusion: There is not a significant relationship between dairy products and primary dysmenorrhea in Pelita Harapan University Medical Students.
