Information technology has been previously used for the research and practice of health promotion. Appropriate and effective health promotion methods used by professional groups remain to be investigated. This study aimed to assess the feasibility and effectiveness of a weight management program among the Chinese occupational population using and a novel information technology exercise prescription.
A 3-month open, self-monitored intervention trial, involving individualized pedometer-assisted exercise prescription and a one-time targeted dietary guidance prior to exercise was conducted on the Chinese occupational population aged 18-65 years in China from 2015 to 2016. Data were collected from March 2015 to May 2016 and analyzed from June 2016 to August 2016. Participants were also asked to synchronize exercise data of the pedometer to the Internet-based Health System Center daily (at least weekly), by connecting to the personal computer (PC) using a USB cable or via Bluetooth.
Eligible participants included 802 Chinese occupational persons, and 718 of them followed exercise interventions with 89.5% (718/802) adherence to the exercise programs. Of them, 688 participants completed the program with 85.8% (688/802) adherence to the exercise program and their data were analyzed. Weight decreased by 2.2% among all overweight/obese participants, with 1.8% reduction in waist circumference and 3.3% reduction in body fat percentage (p< 0.001). Weight and body fat percentage in normal-weight individuals decreased by 0.7% and 2.5%, respectively (p < 0.01). A weight gain of 1.0% was observed in all underweight participants (p< 0.05), and 68.2% (208/305) of overweight/obese participants experienced weight loss, with an average reduction of 3.5%, with 20.2% (42/208) of them achieving weight loss ≥5%. Blood pressure and fasting serum glucose decreased significantly in both the overweight/obese and the normal-weight individuals (p < 0.05). The incidence of hypertension was significantly lower and lifestyle behavior significantly improved (p < 0.05).
The prescription pedometer-assisted walking intervention can effectively improve exercise adherence and manage weight. This approach was also effective in controlling the risk factors of weight-related chronic diseases.

信息技术此前已用于健康促进的研究与实践。专业群体所采用的适当且有效的健康促进方法仍有待研究。本研究旨在评估一项针对中国职业人群的体重管理计划的可行性和有效性，该计划采用了一种新型信息技术运动处方。
2015年至2016年，在中国对18至65岁的中国职业人群开展了一项为期3个月的开放、自我监测干预试验，包括个性化计步器辅助运动处方以及运动前的一次性针对性饮食指导。数据收集时间为2015年3月至2016年5月，分析时间为2016年6月至2016年8月。参与者还被要求通过使用USB数据线或蓝牙连接个人电脑，将计步器的运动数据每日（至少每周）同步至基于互联网的健康系统中心。
符合条件的参与者包括802名中国职业人士，其中718人遵循运动干预，运动计划依从率为89.5%（718/802）。其中，688名参与者完成了该计划，运动计划依从率为85.8%（688/802），并对他们的数据进行了分析。所有超重/肥胖参与者的体重下降了2.2%，腰围减少了1.8%，体脂百分比降低了3.3%（p<0.001）。正常体重个体的体重和体脂百分比分别下降了0.7%和2.5%（p<0.01）。所有体重过轻的参与者体重增加了1.0%（p<0.05），68.2%（208/305）的超重/肥胖参与者体重减轻，平均减少3.5%，其中20.2%（42/208）的人体重减轻≥5%。超重/肥胖个体和正常体重个体的血压和空腹血清葡萄糖均显著下降（p<0.05）。高血压发病率显著降低，生活方式行为显著改善（p<0.05）。
处方计步器辅助步行干预可有效提高运动依从性并管理体重。这种方法在控制与体重相关的慢性病危险因素方面也很有效。
