Promoting Changes in Obesogenic Behaviors: Does Coworker Social Support Play a Role?

Abstract

Purpose.

To examine the association between worksite social support and changes in diet, physical activity, and body mass index (BMI).

Design.

Cohort analysis of an underlying randomized, controlled weight gain prevention worksite trial: Promoting Activity and Changes in Eating.

Setting.

The trial occurred in the greater Seattle area.

Subjects.

Baseline and follow-up data were obtained on a nested cohort of employees (n = 958–1078) from 33 small- to medium-sized worksites.

Measures.

Worksite social support, diet, physical activity, and BMI measures were assessed using a self-reported questionnaire.

Analysis.

To adjust for multilevel data and multiple time points, we used generalized estimating equations and logistic mixed models.

Results.

Higher baseline worksite social support was associated with greater changes in fruit and vegetable intake (p= .001; summary food-frequency questions).

Conclusion.

This study does not support a conclusive relationship between worksite social support and health behavior change.
