Obesity prevalence has increased the past decades and has become a serious public health problem. The aim of this six-month assessor-blinded, parallel-group randomized controlled trial was to assess the effect of a tailored telephone and email-based exercise intervention on various measures of body composition in a sample of apparently healthy and physically inactive adults. A total of 111 volunteering adults (40-55 yr) in Southern Norway were randomly assigned to an intervention group (IG; n = 39) or a no-information control group (CG; n = 50), by random allocation numbering. The IG received feedback on their health-related physical fitness, information on guidelines and recommendations for physical activity, a leaflet on national dietary recommendations, prompts and reminders in addition to three tailored exercise programs, one every two months, and fortnightly motivational counselling by email or telephone, alternately. The CG received no follow-up during the intervention period. The main outcome measures: weight, body mass index (BMI), waist circumference (WC) and fat percentage by skinfolds (FP) were assessed objectively at baseline and posttest. A one-way ANCOVA analysis, adjusted for baseline scores, gender, age, and educational level, revealed a larger reduction on all body compositional measures in the IG compared to the CG (p ≤ 0.043), except for BMI when adjusted for baseline scores. Additionally, a significantly higher percentage of the IG (64.1%) achieved a clinically significant reduction in FP compared to the CG (36.2%, p = 0.018). This six-month tailored telephone and email-based exercise intervention induced significant reductions on several measures of body composition in physically inactive adults.

在过去几十年中，肥胖患病率不断上升，已成为一个严重的公共卫生问题。这项为期六个月的评估者盲法、平行组随机对照试验的目的是，评估一项基于电话和电子邮件的个性化运动干预措施，对一组看似健康但缺乏身体活动的成年人身体成分各项指标的影响。挪威南部共有111名年龄在40 - 55岁之间的志愿者成年人，通过随机分配编号，被随机分为干预组（IG；n = 39）或无信息对照组（CG；n = 50）。干预组除了每两个月收到一个、共三个个性化运动计划，以及通过电子邮件或电话交替进行的每两周一次的激励咨询外，还收到了与健康相关的体能反馈、体育活动指南和建议信息、一份关于国家饮食建议的传单、提示和提醒。对照组在干预期间未接受随访。主要结局指标：体重、体重指数（BMI）、腰围（WC）和皮褶厚度法测得的脂肪百分比（FP），在基线和测试后进行客观评估。在对基线分数、性别、年龄和教育水平进行调整的单因素协方差分析中，与对照组相比，干预组在所有身体成分指标上的下降幅度更大（p≤0.043），但在对基线分数进行调整后的BMI指标上除外。此外，与对照组（36.2%，p = 0.018）相比，干预组中有显著更高比例（64.1%）的人在FP上实现了具有临床意义的下降。这项为期六个月的基于电话和电子邮件的个性化运动干预措施，使缺乏身体活动的成年人在多项身体成分指标上有显著下降。
