Improving the usability of large emergency 911 data reporting systems: A machine learning case study using emergency incident descriptions.

Introduction: Emergency 9-1-1 incident data are recorded voluntarily within fire-department-specific computer-aided dispatch systems. The National Fire Incident Reporting System serves as a repository for these data, but inconsistency and variability in reporting practices across departments often lead to challenges in data quality and utility. This study aims to enhance emergency incident categorization and explore the feasibility of an automated system using free-text incident data from the National Fire Operations Reporting System (NFORS).

Comparison of 24-Hour Movement Behaviors in Desk Workers Across Office and Work From Home Locations.

Objective: Work from home (WFH) is increasingly common, although 24-hour movement behaviors during WFH have rarely been studied. The goal of this study was to compare behaviors among WFH and office-based desk workers.

Methods: This was a secondary analysis of baseline data from the RESET BP randomized clinical trial among inactive desk workers from 2017-2022 ( N = 275).

Impact of sedentary behaviour reduction on desk-worker workplace satisfaction, productivity, mood and health-related quality of life: a randomised trial.

Objectives: Sedentary behaviour (SB) is related to lower worker health-related quality of life (HRQOL), mental health and productivity. However, it is unknown whether reducing SB improves these outcomes. This study assessed whether a 3-month SB reduction intervention improved or was associated with dose-response changes in workplace satisfaction, productivity, mood and HRQOL.

Cardiovascular Responses to Occupational Physical Activity Are Exaggerated by Work-Related Stress and Low Fitness.

Objectives: Paradoxical associations between high occupational physical activity (OPA) and cardiovascular disease may be explained by exaggerated cardiovascular responses from high work-related stress or low worker fitness.

Impact of stress and stress mindset on prevalence of cardiovascular disease risk factors among first responders.

Background: Psychological stress is recognized as an important modifiable risk factor for cardiovascular disease (CVD). Despite its potential significance, few to no studies have evaluated the association between stress, stress mindset, and CVD risk factors among rural first responders. The objectives of this study were to identify relationships between general stress, stress mindset, and CVD risk factors.

Thirteen-Year Associations of Occupational and Leisure-Time Physical Activity with Cardiorespiratory Fitness in CARDIA.

Purpose: Differential effects on fitness are hypothesized to contribute to the opposing health effects of leisure-time physical activity (LTPA) and occupational physical activity (OPA). As such, this study examined cross-sectional and longitudinal associations of fitness with LTPA and OPA.

Methods: This study examined fitness associations with LTPA and OPA across 13 yr in the Coronary Artery Risk Development in Young Adults study (years 7 (baseline), 10, 15, and 20 (follow-up) examinations).

Workers' compensation injury claims among firefighters in Ohio, 2001-2017.

Background: Firefighters are at high risk for nonfatal and fatal occupational injuries. While some past research has quantified firefighter injuries using various data sources, Ohio workers' compensation injury claims data largely have not been used.

Methods: Public and private firefighter claims, including volunteer and career firefighters, from Ohio's workers' compensation data for 2001-2017 were identified based on occupational classification codes and manual review of the occupation title and injury description.

Paradoxical Associations of Occupational and Nonoccupational Sedentary Behavior With Cardiovascular Disease Risk Measures in Desk Workers.

Objectives: We assessed sedentary behavior (SB) patterns and examined its associations, by domain, with cardiovascular disease (CVD) risk measures in desk workers ( N = 273).

Methods: Sedentary behavior was measured by activPAL3 and partitioned into occupational and nonoccupational SB. Cardiovascular disease risk measures included blood pressure, pulse wave velocity, heart rate, and heart rate variability.

Associations of physical and social workplace characteristics with movement behaviors at work.

Introduction/purpose: Sedentary behavior (SB) is common in desk-based work and prolonged periods of SB are associated with negative health outcomes. This study assessed associations between workplace characteristics and setting and movement patterns during working hours.

Methods: This secondary analysis used baseline data from the Reducing Sedentary Behavior to Decrease Blood Pressure (RESET BP) clinical trial which enrolled inactive, desk-based workers with elevated blood pressure (=271; mean age: 45.

Effect of cooling on static postural balance while wearing firefighter's protective clothing in a hot environment.

Postural imbalance can result from hyperthermia-mediated muscular fatigue and is a major factor contributing to injuries from falling. The objective of this study was to investigate the effect of exercise-induced hyperthermia and the impact of cooling on postural balance while wearing firefighters' protective clothing (FPC) in a hot environment. A portable force platform measured postural balance characterized by postural sway patterns using center of pressure metrics.
