Abstract：
This study examined the long-term effects of a lifestyle modification program delivered at German Bundesliga football clubs. Weekly 90-minute group sessions over 12 weeks combined health education and physical activity and were delivered by coaches affiliated with the football clubs. A total of 371 men (mean age 49.7 years [SD = 7.6]) attended 41 classes at 19 clubs in 2017 and 2018 and participated in the long-term follow-up. Primary outcome was weight-loss at follow-up with a mean observation period of 20.4 months after baseline. Measures were taken partly by research staff and partly by participants themselves. At baseline, the men had a mean weight of 111.3 kg (SD = 16.9). Three months after baseline (posttest), the men had lost a mean of 6.3 kg (95% CI: 5.7-6.9). From posttest to follow-up, growth curve model showed men lost an average of 0.8 kg (95% CI: 0.2-1.4). Weight regain from posttest to follow-up of at least 3% was observed in 75 participants (20.2%) and was associated with less improvement in vegetable consumption in an adjusted logistic regression model. The data suggest that participation in a male-only lifestyle modification program offered by German football clubs may lead to sustained weight loss, but lack of a randomized control group and drop-outs prevent generalization of the results.
摘要：
这项研究检查了德国德甲足球俱乐部实施的生活方式改变计划的长期影响。为期12周的每周90分钟的小组会议将健康教育和体育锻炼结合在一起，并由足球俱乐部下属的教练提供。2017年和2018年，共有371名男性（平均年龄49.7岁[SD=7.6]）参加了19个俱乐部的41个课程，并参加了长期随访。主要结果是随访时的体重减轻，平均观察期为基线后20.4个月。部分由研究人员采取措施，部分由参与者自己采取措施。在基线,男性的平均体重为111.3kg(SD=16.9).基线后三个月（后测），男性减重平均6.3kg(95%CI:5.7-6.9).从事后测试到后续，生长曲线模型显示男性平均减重0.8kg(95%CI:0.2-1.4)。在75名参与者（20.2％）中观察到从测后到随访的体重至少恢复了3％，并且在调整后的逻辑回归模型中，蔬菜消费量的改善较少。数据表明，参加德国足球俱乐部提供的仅限男性的生活方式改变计划可能会导致持续的体重减轻，但缺乏随机对照组和辍学阻止了结果的推广。
