Publication Cardiorespiratory Fitness and its Relationship with Adiposity Indices(Institute of Medicine, 2022) Ghimire, Dayaram; Aryal, Vibina; Majumder, Anirban; Manna, SouravABSTRACT Introduction: The cardiorespiratory fitness (CRF) and obesity greatly influence the cardiovascular health. Decrease in maximal oxygen consumption (VO2max) and increase in fat mass can be used as an early marker for cardiovascular disease risk. The objective of this study was to assess the CRF and observe the relationship between CRF and adiposity indices. Methods: A cross sectional observational study was performed in 174 students (87 males and females each) of National Medical College. The subjects were assessed for different adiposity indices; BMI, body adiposity index (BAI), total body fat percentage (BF %) and waist circumference (WC). VO2max was calculated from recovery pulse rate after Queen's College Step Test. VO2max was correlated separately with each parameter of body composition using Pearson’s correlation test. Results: The VO2max of male and female participants were 47.22 ± 9.09 and 35.67 ± 5.36 ml/kg/min respectively. The correlation of VO2max was significant with all the studied adiposity indices. WC (r= - 0.41, p< 0.001) and BF% (r= -0.38, p< 0.001) correlation with CRF was highly significant in male whereas in female correlation was highly significant with BMI (r= 0.49, p< 0.001), WC (r= -0.40, p< 0.001) and BF% (r= -0.56, p<0.001). VO2max correlated best with waist circumference in male (r= - 0.41, p< 0.001) and BF% in female (r= -0.56, p<0.001). Conclusion: This study concludes that there is an adverse relationship between CRF and adiposity indices and females have low level of cardiorespiratory fitness.

Enlarged prostate can be evaluated by digital rectal examination (DRE) and ultrasound. Serum prostate-specific antigen (PSA) has been suggested as a reliable tool to estimate prostate volume (PV) and to predict the diagnosis of prostate cancer. The aim of this study is to correlate prostate-specific antigen with clinical data like age and international prostate severity score (IPSS), DRE finding and PV among subjects with LUTS. Methods: Total of 175 cases were included in the cross-sectional study who presented with LUTS in the Urology Department. DRE was done and noted. Then the cases were advised for ultrasonography (USG) and serum PSA level was sent for investigation. According to the history given by the cases IPSS was done using the IPSS scoring questions. The result was obtained by grouping the cases according to the level of serum PSA. Results: The mean age of the total 191 cases was 72.23±10.46 years and mean PSA level in our study population was 9.08±23.69 ng/ml. Grade III PV was seen among 47.1% of the study population. IPSS scoring between 8-19 was seen among 68.1% study population. Correlation between serum PSA and age group (p=0.007) was significant. High significance (p<0.001) was seen in correlation between serum PSA and DRE finding, IPSS and PV. Conclusion: Our study showed that serum PSA level plays an important role in the evaluation of prostate enlargement. The level of serum PSA along with presenting symptoms and clinical findings can help us to plan our mode of treatment accordingly.

The adverse effect of obesity can be seen in different physiological functions. Relative fat mass is a newly identified parameter to estimate whole body fat. This study aimed to find out the prevalence of obesity among medical students of a medical college. Methods: A descriptive cross-sectional study was carried out among medical students of a medical college from 1 September 2021 to 30 January 2022. Ethical approval was taken from the Institutional Review Committee (Reference number: FNMC/539/078/79). Simple random sampling was done. Height was measured using a stadiometer and waist circumference was measured using non-stretchable tape. Relative fat mass was calculated using the relative fat mass equation. The data was categorised according to the distribution of fat mass. Point estimate and 95% Confidence Interval were calculated. Results: Out of 180 medical students, 57 (31.67%) (24.87-38.47, 95% Confidence Interval) were obese according to relative fat mass cut-off. The mean fat mass among male and female participants with high relative fat mass was 27.057±1.42 and 35.674±2.63 respectively. Conclusions: The prevalence of obesity was lower than in other studies done in similar settings.
