Statistical analysis
weight loss, SD
The feasibility of the study was defined as having at least 80% of participants complete the follow-up online surveys at week 15. The feasibility of the weight loss intervention was defined as the percentage of participants in the weight loss group who completed the 15-week intervention. With 27 participants in the weight loss group, if the true completion rate was 80%, we had 92.5% power to rule out the unacceptable 50% completion rate with 95% confidence (one-sided).The acceptable adherence of the weight loss intervention was defined as the percentage of participants in the weight loss intervention group who engaged in at least 75% of the weekly telephone counseling sessions. Other feasibility assessments, such as the reasons for ineligibility, reasons for refusal among eligible participants, barriers to adherence to weekly sessions, and reasons for dropout, were also assessed.Descriptive statistics, including age, gender, self-reported BMI, and health conditions, were reported overall and compared between those who consented to the study and those who met the eligibility criteria but were excluded. Among those who were enrolled in the study, demographic characteristics, baseline weight, body composition, and objective-measured physical activity were reported with means/standard deviations (SD) for continuous variables and frequencies for categorical variables by study group. The feasibility of the study and the weight loss intervention, and the adherence of the weight loss intervention (as defined above) were calculated.
