We investigated if the studies included in a Cochrane Review had examined and reported adverse effects of lifestyle intervention for weight loss in children. We evaluated each of the 70 RCTs included. A total of 67 trials (96%) did not report a method for monitoring adverse effects. Six trials (9%) reported physical adverse events. One trial reported a "negative effect on children's feelings". None of the 70 studies examined for or reported social adverse effects. In conclusion, only a few studies of lifestyle intervention for weight loss in children examined for potential harm, and 96% did not meet the present-day standard for reporting trials as described in the CONSORT statement.
