Screening of Kidney Dysfunction and its Associated Risk Factors among Public School Learners in La Union National High School, City of San Fernando, La Union

Abstract

This study aimed to detect early signs of kidney dysfunction and its relationship with physiological, demographic, and behavioral risk factors among public secondary learners at La Union National High School. Using a descriptive-correlational research design, 20 participants (65% male, 35% female) underwent urinalysis screening, including albumin-creatinine ratio (ACR), alongside physiological profiling and structured questionnaires. Findings showed a high prevalence of abnormal renal markers, with 18 of 20 respondents (90%) identified by the physician as having kidney dysfunction, while 2 (10%) were normal. Among abnormal cases, hematuria was detected in 15 (75%) respondents, proteinuria (albuminuria) in 14 (70%), and bilirubinuria in 12 (60%) based on urinalysis parameters. Physiological assessment revealed that 50% had abnormal Body Mass Index and 55% had abnormal core temperature, while most maintained normal blood pressure. However, one-way ANOVA showed no significant differences between kidney dysfunction and age, gender, BMI, pulse rate, blood pressure, and temperature. Participants demonstrated “excellent” hydration practices (mean = 3.26) and “good” dietary and drug intake habits, yet these behaviors had no significant association with kidney dysfunction findings. The results emphasize the need for early school-based kidney screening and confirmatory testing among learners who may appear asymptomatic or low-risk.
