Correlations between Results of Physical Examination and Red Blood Cell Testing of Working-Age Populations in Suburbs Society of Lampang Province

Abstract

This retrospective, descriptive, cross-sectional study was to examine the correlation between physical examination results (body mass index (BMI), pulse rate, blood pressure) and pulmonary function, and results of red blood cell testing (hemoglobin, hematocrit, red blood cell concentration, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration). Data were collected from physical examination and blood test record form of the working-age population, aged 20-59 years, in the suburban society of Lampang Province. There were 788 cases including 257 males and 531 females. The data were collected between October 26 to November 3, 2024. Descriptive statistics were used to analyze, and correlation coefficients were determined. The results shown that in healthy men age was negatively correlated with the first three values of red blood cell test, while BMI and diastolic blood pressure were positively correlated with the first three values of red blood cell test. In women, age was correlated only with mean corpuscular volume, while BMI, pulse rate, systolic blood pressure, and diastolic blood pressure were correlated with several values of red blood cell test. These results suggest that some physical examination values have the potential to be used as indicators for red blood cell test results. Which can be further use for laboratory diagnosis of anemia, especially in the working-age population. However, the physiological mechanisms of these correlations need to be further studied.
