dc.description.abstractIntroduction:Obesity is one of the diseases that is a problem of the world nowadays where it is a complex multifactorial disease. Obesity is also a serious problem in Indonesia with a prevalence of 23.1%. Obesity induces the formation of reactive oxygen species (ROS) which is produce oxidative stress that is involved in various pathological processes. Some of the known oxidative stress biomarkers are malondialdehyde (MDA) which is a highly toxic molecule. Ramadan fasting is one of the pillars of Islam that must be implemented by every Muslim around the world for a full month during the month of Ramadan (Hijri calendar). In Indonesia, Muslims are fasting for 13-14 hours. In addition to holding food and drinking, during fasting is also forbidden to smoke, sexual intercourse and is encouraged to resist emotions. Fasting or Intermittent Fasting may decrease inflammation and the oxidative stess via an Autofagi acvation. IF lowers insulin levels in circulation and fasting blood sugar levels, parallel to the increased concentration of growth hormone and insulin sensitivity. IF is an effect on the cardiovascular system by lowering blood pressure, cholesterol concentration, LDL, and triglycerides. IF also relates to weight loss and abdominal fat so as to fix the metabolic marker significantly. The effect of Ramadan intermittent fasting (RIF) on oxidative stress is still unclear and there is a difference among some research based on the background above the researchers interested in conducting research on the effect of fasting Ramadan Against oxidative stress (MDA levels) in individuals with obesity. Method: This research is a prospective cohort. The study was held on March – May 2019 at RSUP Outpatient. H. Adam Malik Medan with the approval of the FK USU Research Ethics Commission and according to the criteria of inclusion and exclusion. The Data is analyzed by using the SPPS program where p < 0.05 is considered significant. Results: The results of the study obtained a meaningful decline in the level of MDA before and after the fasting of Ramadan (p < 0.001). The median rate of MDA before Ramadan was 4.88 nmol/ml (1.68-101,5 nmol/ml) and after Ramadan fasting the median rate of MDA became 3.96 nmol/ml (0.97-92,20 nmol/ml) Conclusion: There was decreased of oxidative stress parameter Malondialdehyde(MDA) levels after Ramadan fasting in obese patients.

dc.description.abstractPendahuluan.Obesitas merupakan salah satu penyakit yang menjadi masalah dunia saat dewasa ini dimana merupakan suatu penyakit multifaktorial yang kompleks. Obesitas juga menjadi masalah yang serius di Indonesia dengan prevalensi 23,1%. Obesitas menginduksi pembentukan reactive oxygen species (ROS) yang kemudian menghasilkan stres oksidatif yang terlibat pada berbagai proses patologis. Beberapa biomarker stres oksidatif yang diketahui yaitu malondialdehyde (MDA) yang merupakan molekul yang sangat toksik.Puasa Ramadhan merupakan salah satu rukun Islam yang wajib dilaksanakan oleh setiap muslim di seluruh dunia selama sebulan penuh pada Bulan Ramadhan (Kalender Hijriyah). Di Indonesia, orang Islam berpuasa selama 13-14 jam. Selain menahan makan dan minum, selama berpuasa juga dilarang merokok, berhubungan seksual dan dianjurkan untuk menahan emosi.Puasa atau Intermittent Fastingdapat menurunkan inflamasi dan stess oksidatif melalui aktvasi autofagi. IF menurunkan kadar insulin di sirkulasi dan kadar gula darah puasa, parallel dengan peningkatan konsentrasi hormon pertumbuhan dan sensitivitas insulin. IF berefek pada sistem kardiovaskular dengan menurunkan tekanan darah, konsentrasi kolesterol, LDL, dan trigliserida. IF juga berhubungan dengan penurunan berat badan dan lemak abdomen sehingga memperbaiki marker metabolik secara signifikan. Pengaruh Ramadhan intermittent fasting (RIF) terhadap stres oksidatif masih belum jelas dan terdapat perbedaan diantara beberapa penelitian. Berdasarkan latar belakang diatas peneliti tertarik untuk melakukan penelitian mengenai efek puasa ramadhan terhadap stres oksidatif (kadar MDA) pada individu dengan obesitas. Metode: Penelitian ini merupakan kohort prospektif.Penelitian dilaksanakan Maret – Mei 2019 di rawat jalan RSUP.H. Adam Malik Medan dengan persetujuan Komisi Etik Penelitian FK USU dan sesuai kriteria inklusi dan eksklusi. Data dianalisis dengan menggunakan program SPPS di mana p<0,05 dianggap signifikan. Hasil: Dari hasil penelitian didapatkan penurunan bermakna kadar MDA sebelum dan setelah puasa Ramadhan (p<0,001). Median kadar MDA sebelum puasa Ramadhan adalah 4,88 nmol/ml (1,68-101,5 nmol/ml) dan setelah puasa Ramadhan median kadar MDA menjadi 3,96 nmol/ml (0,97-92,20 nmol/ml). Kesimpulan: Didapatkan penurunan parameter stres oksidatif kadar malondialdehyde (MDA) setelah puasa Ramadhan pada pasien Obesitas. Kata kunci: Puasa Ramadhan, Obesitas, Malondialdehyda(MDA)en_US
