PMID: 8503351;Abstract:
The ability of dual-energy x-ray absorptiometry (DEXA) to detect small changes in body composition was studied in 17 men and women during a dehydration-rehydration protocol. Scale weight (BW) and total mass (TM) from DEXA were highly related (r > 0.99) as were estimates of fat-free mass (r = 0.99) and percent fat (r = 0.97) from DEXA and densitometry. Changes in BW of ≈1.5 kg due to fluid loss and gain were highly correlated (r = 0.90) with both changes in TM and soft-tissue mass (STM) by DEXA but less so (r = 0.67) with changes in lean-tissue mass (LTM). Mean changes in TM, STM, and LTM were not different (P > 0.05) from changes in BW. Estimates of bone mass and fat were unaffected by changes in hydration. We conclude that DEXA is able to detect small individual changes in TM and STM and is also useful for detecting group changes in LTM.

Background. Inadequate opportunities for physical activity at school and overall low levels of activity contribute to the high prevalence of overweight and obesity in American-Indian children. Methods. A school-based physical activity intervention was implemented which emphasized increasing the frequency and quality of physical education (PE) classes and activity breaks. Changes in physical activity were assessed using the TriTrac-R3D accelerometer in a subsample of 580 of the students (34%) randomly selected from the Pathways study cohort. Baseline measures were completed with children in second grade. Follow-up measurements were obtained in the spring of the fifth grade. Results. Intervention schools were more active (+6.3 to +27.2%) than control schools at three of the four sites, although the overall difference between intervention and control schools (∼10%) was not significant (P > 0.05). Boys were more active than girls by 17 to 21% (P ≤ .01) at both baseline and follow-up. Conclusions. Despite the trend for greater physical activity at three of four study sites, and an overall difference of ∼10% between intervention and control schools, high variability in accelerometer AVM and the opportunity to measure physical activity on only 1 day resulted in a the failure to detect the difference as significant. © 2003 American Health Foundation and Elsevier Science (USA).

PMID: 18309301;Abstract:
Objective: The purpose of this study was to compare weight regain in a group of perimenopausal women (48.0 ± 4.4 years old), randomized to a 12-month weight maintenance Internet intervention or to self-directed weight maintenance after a 4-month weight loss treatment. Methods and Procedures: After a 4-month behavioral weight loss program, 135 women were randomized to either Internet or self-directed groups. The Internet group (n = 66) used a website to gain information and complete logs concerning their weight, diet, and exercise progress over a 12-month follow-up. The 69 self-directed women had no contact with study staff. All women were measured for weight and body composition, and diet intake, and were interviewed using the 7-day physical activity questionnaires at baseline, 4 months, and 16 months. Results: At the end of the 12-month follow-up, the Internet and self-directed groups had regained on average 0.4 ± 5.0 kg and 0.6 ± 4.0 kg, respectively (P = 0.5). In within-group analyses, Internet diet-log entries were correlated with follow-up weight change (r = -0.29; P 0.05) and moderately with change in exercise energy expenditure (EEE; r = 0.44; P 0.01). Follow-up weight change was not correlated with change in dietary intake. Discussion: While significant weight loss was maintained over follow-up by both groups of women, Internet use did not surpass self-direction in helping to sustain weight loss. Among Internet users, Internet use was related to weight change and EEE. © 2008 The Obesity Society.
