Calculating blood pressure and BMI increase caused by night shift construction working using an android-based application

Abstract

The purpose of this study was to assess cardio metabolic disorders earlier by measuring Body Mass Index (BMI), Blood Pressure and Physical Fitness (VO2max). This study was an observational study with cross sectional approach conducted on CV Harith construction by taking subject of 30 peoples by randomly purposive which met the inclusion criteria. Workers shifted morning work then performed night shift each for 2 weeks before they were measured. This study uses the Dependent t test to determine morning and night shift differences. The results showed that there were significant increased on BMI and blood Pressure with p less than 0, 001 but there was no significant decreases on Physical fitness among night and day shift working. This study shows night shift in construction workers causes a significant increase in blood pressure and BMI but does not show significant changes in worker physical fitness.
