PURPOSE: To assess the average distance traveled by healthy adult Pakistanis (different age groups and sex) in six minutes and compare it with other races.

METHODS: This study was conducted in Pakistani nationals, aged 15-65 years at Ojha Institute of Chest Diseases (OICD) and Aga Khan University Hospital (AKUH) in healthy individuals. Subjects with smoking history of >10 pack years, body mass index >30, history of arthritis, COPD, CCF, angina, DM, or other chronic medical condition was excluded from the study.A standard protocol was used in which subjects were instructed to walk from one end to the other of a corridor at their own pace, while attempting to cover as much ground as possible in the allotted 6 min.Subjects were allowed to stop and rest during the test, but were instructed to resume walking as soon as they felt able to do so. Pulse, blood pressure, oxygen saturation (SaO2), and dyspnea severity, were assessed at the start and end of the tesT.

RESULTS: One hundred and ninety three subjects completed the study according to protocol.Out of 193 subjects 119 (%) were male. The mean age, height and body mass index (BMI) were 40.43 ±14.37 years, 162.45±10.43 cm and 23.39±3.45 Kg respectively. The mean heart rate and oxygen saturation before and after the test were 82, 88 and 96.85, 96.94% respectively. The mean distance traveled in six minutes was 477.31±93.64 meters. (Male: 514.99±76.97 Females: 416.71±86.31).

CONCLUSION: This first study from Pakistan showed comparatively low value of 6MWD of healthy adults in comparison to Americans and Caucasians.

CLINICAL IMPLICATIONS: The normal values will help both in diagnosis and follow up of patients with chronic lung diseases.
