Notes: 1) Week 8 change equals week 8 value minus baseline value; 2) BMI, body mass index; 3) MAQ, Modifiable Activity Questionnaire (average hours of activity per week; 4) DXA, dual-energy X-ray absorptiometry; 5) BMC, bone mineral content; 6) p values were based on ANCOVA comparing between group differences in week 8 changes controlling for baseline values, age and education.
