“…13,15,17,20 Nevertheless, only one of them (Ulrich et al) 20 gave age-by-age reference values (Table 4). This study along with ours demonstrated a decline in the 6MWD after the age of 12; however, both the decline and resurrection of the 6MWD were more obvious in our study.…”

INTRODUCTION:Normal values of the 6-min walk distance (6MWD) for children have not been well demonstrated. This limits the interpretation of the 6MWD in children. METHODS: A crosssectional prospective study was designed. A total of 949 (467 males, 482 females) healthy children were recruited randomly from 7 Turkish secondary schools in Ankara. The 6-min walk tests were conducted according to the American Thoracic Society guidelines. RESULTS: The mean 6MWD decreased between the ages of 12 and 14 y for both boys and girls, and then gradually increased until 17 y of age. In the best fitting and most efficient linear, quadratic, and categorical regression models, the age of the subjects, heart rate after the test, and physical activity level of the subjects were significantly related to the 6MWD. Nevertheless, these variables explained < 20% of the variance in the 6MWD. CONCLUSIONS: The 6MWD does not increase in a straight linear fashion from the age of 12 until adulthood. Correlation of the 6MWD with anthropometric features is very weak, so in evaluating the 6MWD, the standard curves should be used.

“…Conversely, Priesnitz et al [33] and Ben Saad et al [34] reported increases in 6MWD with increasing age in children and adolescents, respectively. They associated their results with higher degree of maturation among adolescents when compared with children.…”

KEYWORDS 6-minute walk distance; 6-minute walk test; predicted equationsAbstract The aims of this study were to determine the 6-minute walk distance (6MWD), establish prediction equations for the 6MWD in apparently healthy Nigerians, evaluate any effects regarding participant sex, and compare measured 6MWDs with the predicted 6MWD from reference equations derived from other populations. Four hundred and twenty two (422) apparently healthy Nigerians participated in the study. The 6-minute walk test was carried out according to the American Thoracic Standard-standardized protocol. The 6MWD obtained from the study was compared with reference values from other foreign populations. There were no significant differences between the mean age and mean weight of the male and female participants. However, significant difference existed in the mean height and mean body mass index (BMI; p < 0.001) of these participants. Male participants covered a statistically significant longer distance than female participants (p < 0.001). The mean 6MWD measured in Nigerian participants (517.6 AE 72.2 m) was statistically lower than 6MWD in Americans, Brazilians, and Tunisians and was higher than in Arabians (p 0.002), respectively. The 6-MWD in healthy Nigerians cannot be predicted by established reference equations from other populations. The regression equations established in this study may better predict the distance for Nigerians.

“…The need for reference equations specific to North African populations has been demonstrated for spirometry, [10][11][12][13][14][15] 6-minute walk distance 16,17 and fatfree mass data. 18 The applicability and reliability of published PNIF reference equations and normal values 8,9 should be assessed as regards North African subjects, in order to avoid erroneous clinical interpretation of PNIF data in this population.…”
