Objective: Evaluate innovative, evidence-based approaches to organizational/supportive environmental interventions aimed at reducing the prevalence of obesity among Dow employees after 2 years of implementation.
Methods: A quasi-experimental study design compared outcomes for two levels of intervention intensity with a control group. Propensity scores were used to weight baseline differences between intervention and control subjects.
Objective: To examine first-year results from a workplace environmental obesity prevention program at The Dow Chemical Company.
Methods: A quasi-experimental cohort study was conducted among employees at nine treatment worksites (n = 8013) who received environmental weight management interventions and three control worksites (n = 2269). Changes in employees' weight, body mass index (BMI), and other health risks were examined using chi2 and t-tests.
Objective: To describe the development, reliability, and validity of the Environmental Assessment Tool (EAT) for assessing worksite physical and social environmental support for obesity prevention.
Methods: The EAT was developed using a multistep process. Inter-rater reliability was estimated via Kappa and other measures.
Objective: This paper presents the formative research phase of a large multi-site intervention study conducted to inform the feasibility of introducing environmental and ecological interventions.
Research Methods And Procedures: Using mixed methods that included an environmental assessment, climate survey, leadership focus groups and interviews, and archival data, information was collected on employee health and job factors, the physical environment, social-organizational environment, and current health programs.
Results: Results show that 83% of employees at the study sites were overweight or obese.
