Abstract

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. Difference-in-differences methods and multilevel modeling were used to control for individual and site-level confounders.

RESULTS

Intervention participants maintained their weight and body mass index, whereas control participants gained 1.3 pounds and increased their body mass index values by 0.2 over 2 years. Significant differences in blood pressure and cholesterol values were observed when comparing intervention employees with controls. At higher intensity sites, improvements were more pronounced.

CONCLUSIONS

Environmental interventions at the workplace can support weight management and risk reduction after 2 years.

摘要

目的

评估创新的、基于证据的组织/支持性环境干预方法,旨在减少道氏员工肥胖症的患病率,为期 2 年。

方法

采用准实验研究设计,将两种干预强度水平的结果与对照组进行比较。使用倾向评分法对干预组和对照组之间的基线差异进行加权。采用差值法和多层次模型来控制个体和地点层面的混杂因素。

结果

干预参与者保持了他们的体重和体重指数,而对照组参与者在 2 年内体重增加了 1.3 磅,体重指数值增加了 0.2。比较干预组员工和对照组员工时,观察到血压和胆固醇值的显著差异。在干预强度较高的场所,改善更为明显。

结论

工作场所的环境干预可以在 2 年后支持体重管理和风险降低。
