However, due to the patient’s condition, the measurement must use an estimation formula. This study wanted to know the accuracy of the measurement of body weight from the formula commonly used in hospitals. AIM: This study wants to see how accurate the actual body weight predictions are based on measurements of UAC in the ethnics in the province of South Sulawesi. METHODS: The design of this study was cross-sectional. The population of this study was young adults aged 20–29 years. Number of sample is 896 respondents. Sampling consists of 2 stages, namely sample area and research sample. The sampling used was systematic random sampling. The sample size in this study was calculated using the Stanley Lemeshow formula. RESULTS: The results showed that the formula used to predict the patient’s weight, if the formula is calculated using the formula 100% Patient Upper Arm Circumference (PUAC), it is suitable for ethnic Bugis and Mandar male. The formula 90% PUAC is suitable for ethnic Bugis and Mandar and male ethnic Makassarese and Toraja. The formula 85% is suitable for women for all ethnicities. CONCLUSION: It can be concluded that the accuracy of measuring body weight depends on gender and ethnicity, so it is expected that health practitioners in the hospital can adjust the use of formulas according to gender and ethnicity.

Adult and child patient body weight is usually difcult to measure before being given frst aid/ intervention [1]. Based on secondary data from Wahidin Sudirohusodo Hospital, from all patients in September– December 2015, only new patients who could measure their weight were only 23.33%. Some studies found that nearly 47% of patients who had just been admitted to hospital were sufering from malnutrition, and after being treated would increase to 69% [2]. Body weight is needed in the assessment of nutritional status, and determining the nutritional needs of patients. Measurement of body weight every week is an objective parameter, but what is an obstacle is that not all patients treated can be measured in body weight by weight scales. Weight has a relationship with other measurements, such as upper arm circumference (UAC) and body mass index (BMI). Several studies have shown that weight has a very strong relationship with UAC and BMI [3]. With this very strong relationship, weight, UAC, and BMI have the ability to be used as predictors of nutritional status [4]. Research on patients at Stanford University Hospital, San Francisco, United States, has obtained prediction results for UAC predictors and knee height [1]. In addition, there is a formula for predicting body weight from the calculation of combined knee height and UAC for blacks and whites. In China, studies have been conducted to predict body weight from the calculation of combined UAC and hip circumference. These formulas cannot be used as standards for Indonesia because the formula used is the result of research using samples that are physically diferent from Indonesian people [1]. In Indonesia, research has been carried out in the Nutrition Installation of the DR Hospital. Cipto Mangunkusumo for 1 week with a sample of adult age 19–56 years by obtaining formula equations in adults based on UAC with hip circumference and based on UAC with knee height to predict body weight. WHO stressed that adjustments to anthropometric standards in a country must be based on the results of research in the country concerned so that it is necessary to obtain an appropriate formula for Indonesian people.
