Regression equations to estimate the 2‐min walk distance in an adult Asian population aged 40–75 years

Abstract

The equations derived in this study may facilitate the interpretation of the 2MWD in clinical populations in Malaysia, as well as in countries with similar cultural backgrounds to Malaysia.

Two-minute walk test: Reference equations for healthy adults in China

“…At present, the 2MWT has been used in several different diseases and populations (e.g., the frail elderly,[ 6 , 7 ] recent cardiac surgery,[ 8 ] obesity,[ 9 ] stable COPD,[ 10 , 11 ] recent hip fracture,[ 12 ] circulatory insufficiency,[ 8 ] lower limb amputations,[ 13 ] and multiple sclerosis[ 14 ]). Prediction equations for the two-minute walk distance (2MWD) derived from samples of different ethnicities[ 15 – 17 ] have been established, but these equations differ considerably. Although participants in the study by Mirza et al[ 17 ] included Chinese people, the sample size of Chinese participants was relatively small (N = 23) and insufficient to identify potential interactions between the 2MWD and other variables.…”

Although participants in the study by Mirza et al[ 17 ] included Chinese people, the sample size of Chinese participants was relatively small (N = 23) and insufficient to identify potential interactions between the 2MWD and other variables. Moreover, the model in their study cannot be sufficiently validated.…”

“…Moreover, the model in their study cannot be sufficiently validated. Additionally, participants included in studies by Selman et al [ 15 ]and Mirza et al [ 17 ] were not all healthy people. Thus, for these reasons, the previous published equations may be not suitable for Chinese people.…”

“…The aims of this study were as follows: (1) to establish reference equations for the 2MWD in healthy Chinese adults aged 18–85 years, (2) to test its reproducibility, and (3) to compare the measured 2MWD of our cohort with the predicted 2MWD based on previously published equations derived from foreign studies. [ 15 – 17 ]…”

“…Mirza et al . reported an assessment of 2‐min walk tests in healthy adults living in Malaysia . Data were used to generate regression equations to estimate 2‐min walk distance in this population.…”
