title: Participation as a leader in immersion weight loss treatment: a 1-year follow-up study.
abstract: Non-overweight individuals may follow aggressive weight management approaches alongside overweight/obese friends or family members; thus, research has begun to evaluate subsequent effects among non-overweight populations. A prior study evaluated the short-term effects of an immersion weight loss programme on healthy young adult staff leaders. Results indicated that participation seemed to benefit, not harm, the young adults. The current investigation examined 1-year eating disorder and weight trajectories in this sample. The total sample (N = 244) consisted of staff leaders (44.3%) and demographically similar comparison participants who completed eating disorder and weight assessments across four time points: baseline, end of summer, 6-week follow-up and 1-year follow-up. Forty-seven per cent of the original sample responded to all time points (staff leaders n = 60; comparison n = 55). Over the course of 1 year, risk trajectories did not differ between groups. Staff leaders did not report significant changes in body mass index, suggesting that they maintained healthy weight over the course of 1 year. Participation as an immersion weight loss programme leader appeared to be protective against weight gain, without increasing eating disorder risk, for healthy young adults. This provides further support for using weight management interventions across a wide range of individuals.
