Statistical Analysis of BMI and Blood Pressure Variations Across Age Groups and Genders: An ANOVA-Based Study in Dhanbad District, Jharkhand

Abstract

The present study investigates the influence of age and gender on Body Mass Index (BMI), Systolic Blood Pressure (SBP), and Diastolic Blood Pressure (DBP) in adults from Dhanbad District, Jharkhand, using ANOVA-based statistical analysis. Significant differences in BMI and SBP were observed across age groups (p < 0.05), with older age groups showing higher values, suggesting age-related physiological influences on these measures. Conversely, DBP did not differ significantly with age (p > 0.05), indicating relative stability across age groups. Gender analysis revealed significant differences in both SBP and DBP (p < 0.05), with males exhibiting higher blood pressure levels than females, while BMI showed no significant gender-based differences. Effect size measures (η²) indicated moderate associations between age and BMI/SBP, and smaller but significant associations between gender and blood pressure. These findings highlight the importance of considering both age and gender in cardiovascular risk assessment and suggest that targeted interventions should be tailored accordingly to address age- and gender-specific variations in blood pressure and BMI.
