The Impact of Age, Gender, and Physical Activity on Bone Mass Density: A Descriptive Analysis

Abstract

Background and Objective: Bone Mass Density (BMD) refers to the strength of bones, which peaks between the ages of 25 and 35 years. Achieving optimal peak bone mass and maintaining it is crucial to prevent osteoporosis later in life. This study investigates the influence of Age, Gender, and physical activity on BMD, aiming to understand their contributions to bone health. Methods: This descriptive study assessed the impact of Age, Gender, and Physical Activity on Bone Mass Density (BMD). The Kolmogorov-Smirnov test indicated that BMD and age were not normally distributed (p < 0.05). Spearman's Rank Correlation showed a strong negative correlation between Age and BMD (r = -0.942, p < 0.001), but no significant correlations with Physical Activity (r = 0.003, p = 0.850) or Gender (p = 0.171).  Results: The study found that Age is the most influential factor affecting BMD, with a strong negative correlation (r = -0.942). As age increases, BMD tends to decrease, indicating that aging significantly impacts bone strength. Gender and physical activity also played a role but were less significant than age. Discussion: The results confirm that bone strength peaks in early adulthood and declines with age. Although physical activity, especially weight-bearing exercises, can mitigate this decline, age remains the primary factor influencing BMD. Conclusion:  Age is the main factor influencing BMD, with a strong negative correlation. Regular physical activity is crucial for maintaining bone health and preventing osteoporosis. Future research should focus on interventions to enhance bone density with aging.
