Background: Sarcopenia is a disease or condition characterized by the loss of skeletal muscle mass and function. The study was designed and conducted in the Negele Borana town in East Borana Zone, Ethiopia, due to a lack of data from similar studies in the region. Objective: The goal of the study was to determine the severity of sarcopenia as well as adherence to various dietary patterns. Materials and Methods: A cross-sectional study was carried out on 700 old individuals (300 men and 400 women) living in five districts of Ethiopia’s East Borana Zone. From August 2020 to July 2021, a simple random sample procedure was utilized to choose 4 of the 10 available public health facilities and catchment districts. The twenty-four-hour recall and food frequency questionnaire were used to gather dietary data. Anthropometrics (Mid-Upper-Arm Circumference), bioelectrical Impedance Analysis (BIA), and a skinfold caliper were used to determine body fat. Dietary patterns were also derived using principal component analysis, which was then compared to nutritional body fats. Principle components analysis was also used to find patterns in the food that was eaten. These patterns were then compared to nutritional outcomes using Pearson Partial Correlations, making sure that energy, age, BMI, and dietary supplements were all taken into account. Data normality was determined using Shapiro, Wilk, and the histogram. To assess the relationship between dependent and independent variables, bivariate and multivariable analyses were used. Results: Participants who ate the most Mediterranean Dietary Pattern foods, such as olive oil, fruits, vegetables, fish, and nuts, had a lower risk of Sarcopenia than those who ate the least (OR = 0.21; 95 percent CI = 0.32, 0.40; P-value = 0.01), whereas those who ate the most Western Dietary Pattern foods, such as sugary or sweet diets, soybeans, refined carbohydrates, and fast foods, had a higher risk of Sarcopenia. The intake of animal proteins, potato chips, and refined carbs was also associated with an elevated risk of sarcopenia (OR = 0.5; 95 percent CI = 0.21, 4.01; P-value = 0.32). Conclusion: Following the Mediterranean Dietary Pattern can assist to reduce the risk of sarcopenia-related problems including falling and fractures.
