Study timeline and activities according to study group in the Men’s Lifestyle Validation Study, Boston, Massachusetts, 2011–2013. The doubly labeled water (DLW), accelerometer, physical activity questionnaire (PAQ), and Activities Completed Over Time in 24 Hours (ACT24) measurements were designed to occur during the same 3-month window (phase) during the study but not during the same week, to avoid artificially high correlations. A subgroup (n = 100) of participants in group 1 completed a second DLW measurement at approximately 9, 12, or 15 months. Dual-energy x-ray absorptiometry (DXA) was conducted in participants residing in the Boston area, where scans were performed and scheduled to occur between DLW measurements 1 and 2, or as close as possible to this range. DXA was repeated once in a subset (n = 99) of participants in group 1 in month 12. RPR, resting pulse rate.
