Background: Orthostatic hypotension (OH) is a condition characterized by a significant drop in blood pressure upon standing, potentially leading to dizziness and falls. Body Mass Index (BMI) has been identified as a potential risk factor for OH, yet the relationship remains underexplored, particularly in specific populations. Objective: This study investigates the association between BMI and the prevalence of OH among adults in Ndola City, Copperbelt Province, Zambia, while also examining the influence of gender on this relationship. Methods: A descriptive cross-sectional study was conducted involving adults aged 16 to 60 years, selected through simple random sampling from local health centers. Data on BMI, blood pressure measurements, and demographic information were collected. Chi-square tests were employed to assess associations between BMI and OH, as well as between gender and OH. Results: The analysis revealed a statistically significant association between BMI and the occurrence of OH (Pearson Chi-Square: 63.8815, p &lt; 0.001). In contrast, no significant association was found between gender and OH (Pearson Chi-Square: 1.8646, p = 0.172). These findings suggest that variations in BMI are related to the prevalence of OH among adults in Ndola City, while gender differences appear to have minimal impact. Conclusion: The study highlights the importance of monitoring BMI as a potential risk factor for orthostatic hypotension in adults. While gender does not significantly influence the occurrence of OH, further research is warranted to explore additional contributing factors and develop targeted interventions for the local population. These insights can inform public health strategies aimed at managing OH related to BMI.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0798/a.php" alt="Hit counter" /></p>
