AB  - PURPOSE: This study describes baseline physical activity (PA) patterns of 
      individuals with type 2 diabetes mellitus (T2DM) enrolled in the multicenter Look 
      AHEAD Study using an objective measure of PA (accelerometry). METHODS: A total of 
      2240 participants (age = 59.0 +/- 6.8 yr and body mass index (BMI) = 36.5 +/- 6.0 
      kg.m-(2)) with T2DM provided data for this substudy. Participants were instructed 
      to wear an accelerometer during waking hours for 7 d. Accelerometry data were 
      analyzed to identify periods meeting the criteria of >/=3 MET.min-(1) for Q10 
      min(moderate- to vigorous-intensity PA (MVPA)) and >/=6 MET.min-(1) for >/=10 min 
      (vigorous-intensity PA (VPA)). Self-reported PA was also assessed with a 
      questionnaire. Accelerometry and self-reported PA data were compared across 
      categories of BMI, sex, race, age, fitness, diabetes medication usage, and 
      history of cardiovascular disease. RESULTS: Self-reported PA was lower at higher 
      levels of BMI, was higher in males, was lowest for African-American/black, and 
      was positively associated with fitness. Multivariate analyses for 
      accelerometer-measured MVPA and VPA showed that more PA bouts per day, minutes 
      per bout, METs per minute, and MET-minutes were associated with higher fitness. 
      For MVPA, bouts per day were higher in men, and METs per minute were higher in 
      women. For VPA, bouts per day was positively associated with increasing age and 
      differed by race/ethnicity. METs per minute were significantly lower at higher 
      levels of BMI and in women. Diabetes medication usage and history of 
      cardiovascular disease were not associated with patterns of PA examined. 
      CONCLUSIONS: Results provide information on factors that contribute to PA 
      patterns in adults with T2DM when PA is assessed using both objective and 
      subjective measures. These data may inform interventions to improve PA in adults 
      with T2DM
