    Background/Objectives: Sedentary behavior (SB) and physical activity (PA) are key determinants of health in occupational settings. This study aimed to analyze the levels of SB, PA, and their associations with health outcomes among Chilean workers using data from the National Health Survey-2017. Methods: A secondary analysis of 2042 workers aged ≥18 years was conducted. Occupations were classified using ISCO-08, and SB/PA were assessed using the Global Physical Activity Questionnaire (GPAQ). Health outcomes included musculoskeletal symptoms, hypertension, diabetes mellitus, metabolic syndrome, and cardiovascular risk. Results: Of the participants, 49.8% were women, and the mean age was 45 years (±13.7). The median SB was 120 min/day, with 32.6% accumulating ≥4 h/day. “Managers” exhibited the highest SB (median: 270 min/day). The median total PA was 123 min/day, and “Skilled agricultural, forestry, and fishery workers” reported the highest PA (median: 330 min/day). The SB (≥4 h/day) was significantly associated with musculoskeletal symptoms (OR: 1.61, 95% CI: 1.21–2.14) and hypertension (OR: 1.53, 95% CI: 1.07–2.18). PA showed no significant protective effect. Conclusions: SB and PA vary significantly across occupational groups. SB is associated with musculoskeletal symptoms. Health promotion programs should be tailored to specific occupational groups.

    <jats:sec><jats:title>Background</jats:title><jats:p>Excessive sedentary time has been negatively associated with several health outcomes, and physical activity alone does not seem to fully counteract these consequences. This panorama emphasizes the essential of sedentary time interruption programs. “The Up Project” seeks to assess the effectiveness of two interventions, one incorporating active breaks led by a professional and the other utilizing a computer application (self-led), of both equivalent duration and intensity. These interventions will be compared with a control group to evaluate their impact on physical activity levels, sedentary time, stress perception, occupational pain, and cardiometabolic risk factors among office workers.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>This quasi-experimental study includes 60 desk-based workers from universities and educational institutes in Valparaiso, Chile, assigned to three groups: (a) booster breaks led by professionals, (b) computer prompts that are unled, and (c) a control group. The intervention protocol for both experimental groups will last 12 weeks (only weekdays). The following measurements will be performed at baseline and post-intervention: cardiometabolic risk based on body composition (fat mass, fat-free mass, and bone mass evaluated by DXA), waist circumference, blood pressure, resting heart rate, and handgrip strength. Physical activity and sedentary time will be self-reported and device-based assessed using accelerometry. Questionnaires will be used to determine the perception of stress and occupational pain.</jats:p></jats:sec><jats:sec><jats:title>Discussion</jats:title><jats:p>Governments worldwide are addressing health issues associated with sedentary behavior, particularly concerning individuals highly exposed to it, such as desk-based workers. Despite implementing certain strategies, there remains a noticeable gap in comprehensive research comparing diverse protocols. For instance, studies that contrast the outcomes of interventions led by professionals with those prompted by computers are scarce. This ongoing project is expected to contribute to evidence-based interventions targeting reduced perceived stress levels and enhancing desk-based employees’ mental and physical well-being. The implications of these findings could have the capacity to lay the groundwork for future public health initiatives and government-funded programs.</jats:p></jats:sec>
