Blue Zones-Based Worksite Nutrition Intervention: Positive Impact on Employee Wellbeing.

“Blue Zones” are geographical regions where people live to be non-agenarians and centenarians with significantly better rates of mental wellness when compared to the average American. It was discovered that these areas have nine unique evidenced-based lifestyle principles, with one of their main principles being the consumption of a plant-based diet. With this in mind, we performed a worksite intervention with the objective of understanding the relationships among Blue Zones knowledge, a plant-based lifestyle, and improvements in overall mental wellness during the COVID-19 pandemic. During spring 2021, we recruited 52 employees from a public, mid-sized university in the southwestern United States to participate in an 8-week virtual intervention that included weekly topic presentations, cooking demonstrations, and Blue Zones education. Participants were also assigned to weekly wellness counseling groups integrating Motivational Interviewing based principles that included additional, relevant conversation topics and support. The final sample (n = 52 participants) had a mean age of 45.6 ± 10.6 years. Participants were predominantly women (84.6%) and nearly half were married (44.2%). The majority attended graduate school (59.6%) and identified as White (84.6%). Paired-samples t-tests indicated significant improvements in all mental wellness outcomes and Healthy Eating Index-2015 (HEI-2015) scores over time (p's < 0.001 to 0.02). Multiple linear regression models revealed that Blue Zones knowledge (β = −0.037, p = 0.010) significantly negatively predicted Patient Health Questionnaire-9 (PHQ-9) scores at 8-weeks. Additionally, multiple linear regression models indicated small group attendance (β = −1.51, p = 0.003) and Blue Zones knowledge (β = −0.81, p = 0.012) significantly negatively predicted sleep scores at 8-weeks. When HEI-2015 total scores were also included at baseline and 8-weeks (post-intervention), Blue Zones knowledge (β = −0.031, p = 0.049) was a borderline significant predictor of PHQ-9 at 8-weeks. Additionally, small group sessions (β = −1.52 p = 0.005) were a significant predictor of sleep at 8-weeks. The intervention illustrated that virtual intervention strategies can improve nutrition and mental wellness for future advancement in life quality and wellbeing.

Work-related factors predict changes in physical activity among nurses participating in a web-based worksite intervention: A randomized controlled trial

BackgroundDespite the numerous benefits associated with physical activity (PA), most nurses are not active enough and few interventions have been developed to promote PA among nurses. A secondary analysis of raw data from a single-centre, three-arm parallel-group randomized controlled trial was conducted to assess whether work-related characteristics and general mood states predict changes in total weekly moderate-to-vigorous intensity PA (MVPA) and average daily step-count among nurses participating in a 6-week web-based worksite intervention.MethodsSeventy nurses (meanage: 46.1 ± 11.2 years) were randomized to an individual-, friend-, or team-based PA challenge. Participants completed questionnaires pre- and post-intervention assessing work-related characteristics (i.e., shift schedule and length, number of hours worked per week, work role) and general mood states (i.e., tension, depression, anger, confusion, fatigue, vigour). Participants received a PA monitor to wear before and during the 6-week PA challenge, which was used to assess total weekly MVPA minutes and average daily step-count. Data were analyzed descriptively and using multilevel modeling for repeated measures.ResultsChange in total weekly MVPA minutes, but not change in average daily step-count, was predicted by shift schedule (rotating vs. fixed) by time (estimate = − 17.43, SE = 6.18, p = .006), and work role (clinical-only vs. other) by time (estimate = 18.98, SE = 6.51, p = .005). General mood states did not predict change in MVPA or change in average daily step-count.ConclusionsGiven that nurses who work rotating shifts and perform clinical work showed smaller improvements in MVPA, it may be necessary to consider work-related factors/barriers (e.g., time constraints, fatigue) and collaborate with nurses when designing and implementing MVPA interventions in the workplace.Trial registrationClinicalTrials.gov: NCT04524572.

Colleagues affect healthy eating and exercise behavior

Abstract Exercising and eating healthy are not just an individual choice, but influenced by the social environment. Family members, friends or neighbors influence (un)healthy choices individuals make, yet little is known about other important contacts: colleagues. Many people spend at least 8 hours a day at work, mostly surrounded by the same colleagues. As a third of daily calories are consumed in the workplace and a lot of time is spent sitting there, colleagues could be important in shaping the (un)healthy choices employees make. We study to what extent colleagues influence each other's eating and exercise behavior. We focus on two pathways: colleagues can encourage a healthy lifestyle or act as role models whose behavior can be observed and copied. We use the European Sustainable Workforce Survey, with data on 4345 employees in 402 teams in 113 organizations. We measured healthy eating as how often employees eat fruit and vegetables. We measured exercise by the number of days in the past week employees did sports/physical activity for more than 30 minutes. Colleague encouragement was assessed by the extent to which employees said their colleagues encourage them to eat healthy food or exercise frequently. We computed colleague behavior by taking the average fruit and vegetable consumption, and exercise, of all colleagues in a team. We fitted multilevel models with employees nested in teams and controlled for gender, age, education, working hours, job physical demands, self-rated health, sector and country. Preliminary results show colleague encouragement for healthy eating positively affected fruit consumption (p&amp;lt;.01), colleague fruit consumption did not(p=.62). Both colleague encouragement (p&amp;lt;.01) and colleague vegetable consumption (p=.04) positively relate to vegetable consumption. Colleague encouragement positively (p=.03), and colleague exercise behavior (p&amp;lt;.01) negatively, affected exercise. Worksite health interventions should emphasize the role colleagues may play. Key messages Next to family, friends and neighbors, also colleagues influence each other’s eating and exercise behavior. Worksite health interventions should the role colleagues may play into account when attempting to improve employee health.

Adverse employment histories, work stress and self-reported depression in the French CONSTANCES study.

BackgroundJob instability and disadvantaged work were shown to be associated with poor mental health, but few studies analyzed these conditions in a life course perspective. In this study, adverse employment histories are retrospectively assessed and linked to self-reported depression. Furthermore, indirect effects of later stressful psychosocial work in terms of effort-reward imbalance are investigated.MethodsWith data from the French CONSTANCES cohort study of 13 716 male and 12 767 female employees aged 45 and older, we identify adverse employment histories between age 25 and 45, focussing on job discontinuity, job instability and cumulative disadvantage. Direct effects of these conditions on self-reported depression over a period of up to 5 years are analyzed, using discrete-time logistic regression. Indirect effects of stressful work at baseline are examined.ResultsModerately elevated odds ratios of self-reported depression are observed among participants with discontinued employment histories (number of unemployment periods; years out of work for men). Effort-reward imbalance at work is consistently related to elevated risk of self-reported depression and explains parts of the association between discontinuous employment and depression.ConclusionsApplying a life course perspective to occupational health research extends current knowledge. Specifically, adverse employment histories in terms of recurrent job discontinuity are related to the risk of self-reported depression. This association is partly explained by exposure to a stressful psychosocial work environment. These results can instruct labour market policies and the development of targeted worksite interventions that address disadvantage throughout entire employment trajectories.

Effectiveness of Workplace Exercise Interventions on Body Composition: A Systematic Review and Meta-Analysis.

The aim of this review was to analyze the effectiveness of workplace exercise interventions on body composition (BC). Studies published in PubMed, Scopus, SPORTDiscus, Web of Science, CINAHL and PsycINFO, from the earliest time point until 8 July 2020. Inclusion criteria were worksite interventions, in adults, Randomized Controlled Trials (RCTs), real exercise practice, and measuring BC outcomes. Exclusion criteria were full-text non-available, abstract not in English, and exercise protocol missing. 157 studies were retrieved and assessed for inclusion by 2 independent reviewers, who also used the Cochrane's Collaboration Tool to assess study quality and risk of bias. We performed a meta-analysis to determine the effect size of the interventions on BC outcomes reported in at least 5 studies. Twelve RCTs were included (n = 1270, 66% women), quality of studies being low to high (25% moderate, 67% high). Interventions achieved a statistically significant decrease in waist circumference (SMD = 0.24; 95% confidence interval (CI): 0.06 to 0.41; p = 0.008), total mass fat (SMD = 0.21; 95%CI: 0.00 to 0.41; p = 0.047), and body adiposity index (SMD = 0.20; 95%CI: 0.00 to 0.41; p = 0.049). No changes were observed in body weight (SMD = 0.08 95%CI: -0.02 to 0.18; p = 0.128). Additionally, muscle mass increased in interventions that included strength training. There were no adverse events reported. The most effective workplace exercise interventions to improve BC combined supervised, moderate-intensity aerobic and strength training, for at least 4 months.

A Worksite Self-management Program for Workers with Chronic Health Conditions Improves Worker Engagement and Retention, but not Workplace Function

Purpose An increasing number of workers in the US have chronic health conditions that limit their ability to work, and few worksite interventions have been tested to improve worker coping and problem solving at work. The purpose of this study was to evaluate a worksite-based health self-management program designed to improve workplace function among workers with chronic health conditions. Methods We conducted a randomized, controlled trial of a worksite self-management program (“Manage at Work”) (clinicaltrials.gov #NCT01978392) for workers with chronic health conditions (N = 119; 82% female, ages 20–69). Most workers were recruited from the health care or light manufacturing industry sectors. Workers attended a 5-session, facilitated psychoeducational program using concepts of health self-management, self-efficacy, ergonomics, and communication. Changes on outcomes of work engagement, work limitation, job satisfaction, work fatigue, work self-efficacy, days absent, and turnover intention at 6-month follow-up were compared to wait-list controls. Results The most prevalent chronic health conditions were musculoskeletal pain, headaches, vision problems, gastrointestinal disorders, respiratory disorders, and mental health disorders. The self-management program showed greater improvement in work engagement and turnover intent at 6-month follow-up, but there was no evidence of a parallel reduction in perceived work limitation. Trends for improved outcomes of work self-efficacy, job satisfaction, and work fatigue in the intervention group did not reach statistical significance in a group x time interaction test. Conclusions Offering a worksite self-management program to workers with chronic health conditions may be a feasible and beneficial strategy to engage and retain skilled workers who are risking disability.Clinical trial registration: Clinicaltrials.gov #NCT01978392.

Unloading and Reloading Process for the Earthquake Damage Repair of Ancient Masonry Columns: The Case of the Basilica di Collemaggio

ABSTRACT The repair of historical masonry columns damaged by earthquakes is a complex engineering procedure. In most cases, these elements support important vertical loads, and, for this reason, the repairing interventions (such as block replacement) could generate critical modifications of the stress pattern and eventually lead to local failures of the masonry material. In order to prevent critical situations, the repair work should account a complete unloading-reloading process of the column. However, at this time, no specific indications are provided by technical codes and guidelines. In the present paper, the unloading-reloading process developed for the stone masonry columns of the Basilica di Collemaggio in L’Aquila (Italy) is presented. Particularly, two specific unloading systems were designed and verified with advanced finite element analyses. A three-dimensional finite element model of the colonnade and supported nave wall was implemented to check if the unloading-reloading process would significantly change the state of stress in the masonry, causing local failures. The geometry of the structure was reconstructed from a complete laser scanner survey of the church, by considering all the intrinsic irregularities of heritage constructions. Finally, a comparison between the numerical results and the corresponding values measured during the worksite intervention was carried out.

Implementation of a workplace physical activity intervention in child care: process evaluation results from the Care2BWell trial.

Care2BWell was designed to evaluate the efficacy of Healthy Lifestyles (HL), a worksite health promotion intervention to increase child care workers' physical activity. The purpose of this study was to use process evaluation to describe the implementation of HL and determine if different levels of implementation are associated with changes in workers' physical activity. Data were collected from 250 workers randomized to HL, a 6 month, multilevel intervention that included an educational workshop followed by three 8 week campaigns that included self-monitoring and feedback, raffle incentive, social support, and center director coaching. Process evaluation data collection included direct observation, self-reported evaluation surveys, website analytics and user test account data, tracking databases and semi-structured interviews. Implementation scores were calculated for each intervention component and compared at the center and individual levels. Nearly a third of workers never self-monitored and few (16%) met self-monitoring goals. Only 39% of centers engaged with the social support component as intended. Raffle and social support components were perceived as the least useful. Implementation varied widely by center (25%-76%) and individual workers (0%-94%). No within- or between-group differences for high compared to low implementation groups for change in physical activity were evident. Interview themes included limited sustainability, competing priorities, importance of social support, and desire for a more intensive, personalized intervention. Wide variation in implementation may explain limited effects on intervention outcomes. Future worksite interventions designed for child care workers can use these findings to optimize health promotion in this setting.

Impact of a nutrition education program on health behaviors in a university workplace wellness program.

Obesity is a complex health issue associated with the leading causes of preventable chronic diseases, such as heart disease and type 2 diabetes. As part of an interprofessional team, nurse practitioners can play an integral role in leading worksite interventions to enhance health behavior change. Although worksite nutrition interventions have existed for many years, effective weight management programs are needed in the workplace. The purpose of this study was to determine the effect of a novel nutrition education program implemented in the workplace on health behaviors (dietary habits and physical activity), motivators and barriers, emotional eating, confidence, and biometrics (body mass index and lipid levels). A total of 96 university employees participated in a one-group pre- and postintervention from 2017 to 2019. The intervention included eight weekly face-face education sessions. We assessed dietary habits, physical activity, motivators and barriers of a healthy lifestyle, emotional eating, confidence levels, body mass index, and lipid levels. Descriptive statistics, chi-square test, one-way analysis of variance, and Wilcoxon rank test were performed. The consumption of fruits, vegetables, beans, grains, and physical activity increased significantly. Barriers, body mass index, and triglycerides significantly decreased. There was no significant difference in emotional eating and motivators after the intervention. Nurse practitioners are positioned to lead an interprofessional team to provide nutrition education to help mitigate risk factors for obesity in various settings, including the workplace.

Relationship between Employment Type and Self-Rated Health among Korean Immigrants in the US: Focusing on Gender and Number of Years in the US.

Although Korean immigrants report worse self-rated health and a higher self-employment rate than other Asian immigrant groups, the relationship between their employment type and self-rated health is understudied. This study examines the relationship between employment type and self-rated health among Korean immigrants in the US. Survey data of 421 first-generation working-age (18–64 years old) Korean immigrants in the New York–New Jersey area were analyzed. The self-administrated survey questionnaire included 39 items (e.g., sociodemographic characteristics, self-rated health, and health insurance status). A logistic regression analysis was conducted to examine the relationship between the dependent variable—self-rated health (e.g., bad/not bad vs. good/very good)—and independent variable—employment type (e.g., work at non-ethnic firms, work at co-ethnic firms, self-employed, and unemployed)—by focusing on differences regarding gender and number of years living in the US. Self-employed and unemployed Korean immigrants were less likely to report good health compared to those working in non-ethnic firms. After controlling for sociodemographic characteristics (age, gender, marital status, education, health insurance status, membership in any Koran association, religion, and English proficiency), the relationship between employment type and self-rated health remained significant among female and recent Korean immigrants. More worksite interventions by occupational health nurses that target self-employed Korean immigrants, especially women and recent immigrants, are necessary.

The Necessary Thread of Mindfulness Intervention Fidelity Assurance: Enabling an Organizational Strategy to Promote Health Care Professional Well-Being.

PurposeA growing waitlist for Mindfulness in Motion (MIM), an evidence-based worksite mindfulness-based intervention, necessitated a training system with built in fidelity assurance to meet program demand. MIM was delivered as part of an organizational strategy in a large academic health center to enhance Health Care Professional (HCP) well-being. In order to ensure that the intervention was being delivered the same way to each cohort, a process to ensure intervention fidelity was developed for MIM.MethodThe core components of MIM informed the development of a detailed fidelity monitoring system to ensure consistent intervention delivery. Each MIM cohort was conducted with both trained facilitators and trained intervention fidelity monitors.ResultsAcross 11 cohort offerings of MIM, each 8 weeks in length, there was a mean adherence rate of 0.9886, SD = 0.0012.ConclusionThe fidelity monitoring system allowed for a reliable expansion of MIM offerings to HCPs and for a seamless pivot to fully virtual MIM delivery, necessitated by COVID-19.

The potential role of nutrition in mitigating the psychological impact of COVID-19 in healthcare workers

Healthcare professionals are exposed to several stress factors, especially during health emergency situations like Covid-19. Psychological distress in the COVID-19 era adversely affects both healthcare professionals' mental and physical health, decreasing performance and efficiency at work. Nevertheless, no sufficient emphasis has been placed so far on the role of nutrition against stress and anxiety among healthcare professionals. Consequently, worksite health promotion approaches and interventions are highly recommended, but also National Health Systems are praised to develop strategies and policies to satisfy nutritional requirements in health emergencies such as Covid-19 pandemic. In this brief paper, the important role of nutrition during periods of stress is highlighted, providing nutritional advice to enhance resilience in this risk group. In addition, practical lifestyle and diet tips for stress management among healthcare professionals exposed to Covid-19 are reported in this mini review.

Implementing a Novel Workplace Smoking Cessation Intervention Targeting Hispanic/Latino Construction Workers: A Pilot Cluster Randomized Trial.

U.S. Hispanic/Latino construction workers constitute a large and historically underserved group in terms of smoking cessation services. Using formative research, we developed a worksite smoking cessation intervention tailored to the life/work circumstances of these workers. This study aims to examine the feasibility, acceptability, and potential efficacy of the developed intervention "Enhanced Care" (EC; one group behavioral counseling session provided around the food truck + fax referral to tobacco quitline [QL] + 8-week nicotine replacement treatment [NRT]) compared with "Standard Care" (SC; fax referral to tobacco QL + 8-week NRT) in a pilot, two-arm, cluster randomized controlled trial. In collaboration with construction site safety managers, a sample of 17 construction sites (EC: nine sites/65 smokers; SC: eight sites/69 smokers) was enrolled. Participants received two follow-ups at 3 and 6 months after enrollment. Feasibility outcomes were enrollment rate, adherence to treatment, and 6-month retention rates. The primary efficacy outcome was 6 months prolonged abstinence verified by expired carbon monoxide <10 ppm. Enrollment rate was high (85.9%). Six-month follow-up rates were acceptable (EC = 76.9%, SC = 66.6%). Adherence to treatment was better in the EC group (received worksite intervention: EC = 93.8%, SC = 88.4%; contacted by QL: EC = 49.2%, SC = 40.6%). Abstinence rates were 27.7% for the EC and 20.3% for the SC (p = .315). The developed intervention was feasible and acceptable, and it substantially improved abstinence among Hispanic/Latino workers. The involvement of safety managers was essential to the implementation of the intervention. Training safety managers to deliver the intervention has great potential to implement a sustainable smoking cessation service in the construction sector.

Motivation Predicts Change in Nurses' Physical Activity Levels During a Web-Based Worksite Intervention: Results From a Randomized Trial.

BackgroundLow physical activity levels can negatively affect the health of nurses. Given the low physical activity levels reported by nurses, there is a clear need for brief and economical interventions designed to increase physical activity levels in this population. We developed a web-based intervention that used motivational strategies to increase nurses’ physical activity levels. The intervention provided the nurses with feedback from an activity monitor coupled with a web-based individual, friend, or team physical activity challenge.ObjectiveIn this parallel-group randomized trial, we examine whether nurses’ motivation at baseline predicted changes in objectively measured physical activity levels during the 6-week intervention.MethodsThe participants were 76 nurses (n=74, 97% female; mean age 46, SD 11 years) randomly assigned to 1 of 3 physical activity challenge conditions: (1) individual, (2) friend, or (3) team. The nurses completed a web-based questionnaire designed to assess motivational regulations for physical activity levels before the intervention and wore a Tractivity activity monitor before and during the 6-week intervention. We analyzed data using multilevel modeling for repeated measures.ResultsThe nurses’ physical activity levels increased (linear estimate=10.30, SE 3.15; P=.001), but the rate of change decreased over time (quadratic estimate=−2.06, SE 0.52; P<.001). External and identified regulations (ß=−2.08 to 11.55; P=.02 to .04), but not intrinsic and introjected regulations (ß=−.91 to 6.29; P=.06 to .36), predicted changes in the nurses’ physical activity levels.ConclusionsOur findings provide evidence that an intervention that incorporates self-monitoring and physical activity challenges can be generally effective in increasing nurses’ physical activity levels in the short term. They also suggest that drawing solely on organismic integration theory to predict changes in physical activity levels among the nurses participating in web-based worksite interventions may have been insufficient. Future research should examine additional personal (eg, self-efficacy) and occupational factors (eg, shift length and shift type) that influence physical activity levels to identify potential targets for intervention among nurses.Trial RegistrationClinicalTrials.gov NCT04524572; https://clinicaltrials.gov/ct2/show/NCT04524572

Health Risk Disparities among Employed Adults with COPD Living in Central Appalachian U.S. States

ABSTRACT Background Little is known about risk factors associated with poor health among employees with COPD living in Central Appalachia. Purpose: Determine variability in health distress based on risk factors, including race and income, among employees with COPD from Central Appalachian U.S. States. Methods: 2016–2017 BRFSS data were analyzed from employed adults with COPD living in KY, NC, TN, and WV (N = 1,326). Health risks included (1) comorbidities; (2) substance use/abuse; and (3) limited healthcare access as predictors of mental and physical distress, with race and income entered as covariates. Results: Respondents reporting several comorbidities were more likely to report physical and mental distress compared to those without comorbidities. Workers who used e-cigarettes on some versus no days were more likely to report physical distress. Those reporting cost preventing access to medical care versus no cost barriers were more likely to report physical and mental distress. Low-income workers were more likely than higher-income workers to report distress. Discussion: Comorbidities, e-cigarettes, and high medical costs are potential causes of occupation-related disability among employees with COPD working in Central Appalachian U.S. States. Translation to Health Education Practice: Worksite interventions should address risks negatively associated with health outcomes among workers with COPD from Central Appalachia.

Peer effects in smoking cessation: An instrumental variables analysis of a worksite intervention in Thailand.

While smoking is widely acknowledged to be a social activity, limited evidence exists on the extent to which friends influence each other during worksite-based tobacco cessation interventions. Drawing on data from adult smokers (N = 1823) in a large, cluster randomized controlled trial in worksites in Thailand, this study examines the presence of social spillovers in the decision to abstain from smoking. We leverage a unique aspect of social network structure in these data—the existence of non-overlapping friendship networks—to address the challenge of isolating the effects of peers on smoking behavior from the confounding effects of endogenous friend selection and bidirectional peer influence. We find that individuals with workplace friends who have abstained from smoking during the trial are significantly more likely to abstain themselves. Instrumental variables estimates suggest that abstinence after 3 and 12 months increases 26 and 32 percentage points, respectively, for each additional workplace friend who abstains. These findings highlight the potential for workplace interventions to use existing social networks to magnify the effect of individual-level behavior change, particularly in low- and middle-income countries where tobacco cessation support tends to be limited.

Efficacy Of Smartphone App In Worksite Physical Activity Intervention And Anthropometric Changes In Obese Women

Most U.S. office workers engage in little physical activity and increased time sitting which increases risk for adverse health conditions such as obesity. Research on the effectiveness of smartphone apps to increase physical activity and reduce sitting time in workers in limited. PURPOSE: To examine the efficacy of a smartphone app and worksite physical activity intervention program to increase daily physical activity with the goal of reducing sitting time via walking or increased steps on anthropometric changes over an 8-week period. METHODS: Subjects (N=22) were obese, female volunteers, all of whom had access to a smartphone and the StridekickTM app, that recorded steps, with a progressive goal of 7,500-15,000 daily steps. Relative (%) body fat was measured via DEXA scan, along with five anthropometric measurements, biceps, waist, abdomen, hips and thigh, prior to and after 8 weeks. Dependent samples t tests probed for significant differences at the p<0.05 level. Values are expressed as mean±standard deviation. RESULTS: Significant changes were determined for the pre-post anthropometric measurements: biceps, hips and thigh (12.0+1.1 vs.11.5+1.3; 42.8+5.1 vs. 42.2+5.1; 24.9+2.7, vs. 23.8+2.8 in, respectively). Pre-post BMI, waist, abdomen measurements and % relative fat were not significantly different (31.0+5.7 vs. 30.5 + 5.7 kg/m2; 34.1±4.8 vs. 34.1+4.9 in; 39.2 + 4.7 vs. 39.0 + 4.8 in; 41.4±6.6 vs. 41.8+6.3 %fat, respectively). CONCLUSION: This work is suggestive that the incorporation of a smartphone app into a worksite physical activity intervention may change anthropometric measures via increasing steps and ultimately reduce adverse health concerns.

Impact of a group-based intervention program on physical activity and health-related outcomes in worksite settings

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.
