An internet-based intervention with brief nurse support to manage obesity in primary care (POWeR plus ): a pragmatic, parallel-group, randomised controlled trial

摘要

Background The obesity epidemic has major public health consequences. Expert dietetic and behavioural counselling with intensive follow-up is effective, but resource requirements severely restrict widespread implementation in primary care, where most patients are managed. We aimed to estimate the effectiveness and cost-effectiveness of an internet-based behavioural intervention (POWeR+) combined with brief practice nurse support in primary care.
