Abstract
BackgroundThe benefits of physical activity (PA) have been well documented, and the worksite is a promising setting for PA promotion. The aims of this study were as follows: 1. To evaluate the effect of a group-based worksite intervention on PA and health-related outcomes by using pedometers. 2. To examine the associations between the change in vigorous physical activity (VPA)/moderate physical activity (MPA)/walking and health related outcomes.MethodsA total of 398 participants (221 in the intervention group (IG) and 177 in the control group (CG)) from 17 worksites were recruited for a prospective self-controlled trial of a worksite physical activity intervention program in China. In the IG, a pedometer was utilized to self-monitor the PA, together with group competition, goal setting, and other incentives. No intervention was applied to the CG. Physical activity, sedentary behavior, and health-related outcomes were measured at baseline and immediately after the 100-day period intervention.ResultsA total of 262 participants completed the program (68.3% adherence). Adherence in the intervention group was 67.9% (n = 150/221). Improvements between baseline and follow-up among intervention participants were observed in the following parameters: VPA (+ 109.7 METs/week; p < 0.05), walking (+ 209.2 METs/week; p < 0.01), systolic blood pressure (SBP; − 2.1 mmHg; p < 0.01), waist circumference (WC; − 2.3 cm; p < 0.01), body fat percentage (BF); − 1.0%; p < 0.01), and body mass index (BMI; − 0.5 kg/m2; p < 0.01). VPA was related to changes in body fat percentage (p < 0.05) and body mass index (p < 0.05).ConclusionThis integrated group-based intervention program contributed to comprehensive improvement in health-related outcomes. The study was useful for establishing associations between change in VPA/MPA/walking and health-related outcomes in a natural setting. Long-term evaluation is required to examine the potential of such an integrated intervention to promote PA.RegistrationThis study was prospectively registered in the Chinese Clinical Trial Registry.

Summary
The benefits of physical activity (PA) have been well documented, and the worksite is a promising setting for PA promotion. 2. To examine the associations between the change in vigorous physical activity (VPA)/moderate physical activity (MPA)/walking and health related outcomes. The proportion of Chinese adults aged 20–59 years meeting the minimum recommendation of PA (150 min of moderate exercise per week or 75 min of vigorous exercise per week) was only 22.8% in 2014, while the proportion of obesity increased from 8.6% in 2000 to 12.9% in 2014 [8]. According to the China Kadoorie Biobank study, in which 466,605 Chinese adults were included, the mean level of exercise in those younger than 50 years (for women) and younger than 60 years (for men) was lower than that in those aged 70–79 years [9]
