Abstract

Introduction: Two-minute walk test (2MWT) is used widely to determine the functional capacity in clinical setup. However, reference equations derived from Western population cannot be applied to Indian subjects owing to the ethnic differences. Hence, the current study aimed to establish reference equation for 2MWT in healthy Indian population. Subjects and Methods: A cross-sectional study was conducted in 480 healthy participants in the age group of 20-80 years who performed two 2MWTs using a standardized protocol. The highest value of two-minute walk distance (2MWD) was selected for further analysis. Results: The mean value of 2MWD was 152.33 ± 26.56 m. 2MWD for men (157.3 ± 23.82 m) was higher than females (147.35 ± 28.21 m) (P < 0.001). Bivariate analysis showed that 2MWD correlated significantly (P < 0.05) with age, height, and weight in both genders. Further, stepwise multiple linear regression analysis was performed to generate gender-specific reference equations using age, height, and weight as predictors of 2MWD. Conclusion: We established a gender-specific prediction equation for 2MWD in healthy Indian subjects. It can be used as a reference to interpret functional capacity in patients with acute illness, cardiorespiratory disease, and other health-related conditions.
