Abstract

Body Mass Index (BMI) is a simple parameter used to assess a person's nutritional status, whether they are underweight or overweight. Overweight is often associated with the risk of elevated blood glucose levels (hyperglycemia), which can develop into metabolic syndrome. This condition is increasingly found in adolescents and young adults with unhealthy lifestyles. Therefore, this study was conducted to determine the relationship between BMI and random blood glucose levels (RBG) in regular students of the Diploma III Medical Laboratory Technology program at Wira Medika Bali Health College. This study employed an observational analytical method with a cross-sectional approach. A sample of 30 students was selected through purposive sampling based on inclusion criteria: aged 15–24 years, not taking medications that affect blood sugar levels, and willing to participate. BMI data were obtained through weight and height measurements, then categorized into underweight, normal weight, overweight, obesity I, and obesity II. RBG examinations were performed using capillary blood with the aid of a glucometer. Analysis of the relationship between variables used the Spearman Rank Test. The results showed that the BMI distribution of respondents was 13.3% underweight, 40.0% normal weight, 13.3% overweight, 23.4% obesity I, and 10.0% obesity II. All respondents had random blood glucose levels <200 mg/dL, thus remaining within the normal range. Statistical testing showed a p-value of 0.996 (p>0.05), concluding that there was no significant relationship between BMI and GDS in students. The conclusion of this study is that BMI has not been proven to be directly related to random blood glucose levels. However, weight control remains necessary as a long-term preventive measure against metabolic syndrome and other non-communicable diseases associated with obesity.

Abstract

Urinary Tract Infection (UTI) is one of the most prevalent diseases that requires rapid and accurate laboratory diagnosis. Urine examination using dipstick methods serves as a practical diagnostic alternative. However, the stability of urine specimens subjected to delayed examination needs further evaluation, particularly regarding pH and leukocyte parameters. This study aimed to determine the differences in urine pH and leukocyte results between fresh urine and urine stored for 2 hours at room temperature using the dipstick method in UTI patients. This experimental study employed a quantitative approach. A total of 30 urine samples were collected from UTI patients at RSAD Tk. II Udayana. Each sample was analyzed under two conditions: immediately (fresh urine) and after 2 hours of storage at room temperature (delayed urine), yielding a total of 60 measurements. The results showed an increase in the median urine pH from 6.0 to 6.5 and a decrease in leukocyte count from a median of 125 to 70 after 2 hours of storage at room temperature, with statistically significant differences (p < 0.05). These findings indicate that delaying urine examination for 2 hours can affect pH and leukocyte values, potentially leading to inaccurate diagnostic interpretation. Therefore, urine chemical examination should be performed within one hour after collection or stored at 2–8 °C to maintain result accuracy.
