Acute Effects of Interrupting Sitting on Discomfort and Alertness of Office Workers
Objective: The aim of this study was to compare the effect of 4 hours of sitting interrupted with hourly bouts of standing and/or pedaling versus uninterrupted sitting on alertness and discomfort among sedentary office workers. Methods: Fifteen middle-aged sedentary workers were randomized to three 4-hour conditions: (1) uninterrupted sitting; (2) sitting interrupted with 10 minutes of standing/hour; and (3) sitting interrupted with 10 minutes of pedaling/hour. Self-reported measures of alertness and discomfort were collected. Results: Uninterrupted sitting significantly increased discomfort (P...
Blood Pressure Response to Interrupting Workplace Sitting Time With Non-Exercise Physical Activity
Results of a 12-month Cohort Study Objective: To evaluate the blood pressure (BP) effects of a yearlong e-health solution designed to interrupt prolonged occupational sitting time. Methods: BP data of 228 desk-based employees (45.1 ± 10.5 years) were analyzed at baseline, 3, 6, 9, and 12 months. Results: Systolic BP significantly reduced from baseline for the first 9 months (1.0 to 3.4 mmHg; P < 0.01) while diastolic and mean arterial pressure decreased for the full 12-months (4 to 5 mmHg for diastolic pressure and 3.6 to 4.2 mmHg for MAP; all P < 0.01). Participants used the e-health...
Work-related physical, psychosocial and individual factors associated with musculoskeletal symptoms among surgeons
Implications for ergonomic interventions This study evaluated the effect of physical, psychosocial and individual factors on the presence of musculoskeletal symptoms (MSS) among surgeons (n = 312) in Iran. Data were collected using questionnaires and analysed by multivariate logistic regression. The prevalence of MSS, particularly in the knees (48.7%), neck (45.8%), low back (42.3%) and shoulders (40.1%) was relatively high. Work-related factors including time spent on surgeries each week (>25 h/week), number of hours working in standing position per day (>4 h/day), moderate to high levels...
Total Worker Health® Concepts to Reduce the Health Risks from Sedentary Work

An integrated approach is one that protects workers from work-related injury and illness and helps them advance their overall health and well-being, on and off the job. This document describes organizational practices that can reduce the risks associated with sedentary work. Source: https://www.cdc.gov/niosh/docs/wp-solutions...
