Key result
Workplace lifestyle program is linked to a ~7-unit boost in diet quality and better lipid profiles.
Why the study?
Overall diet quality is included in American Heart Association cardiovascular health criteria, but the effect of targeting diet quality and physical activity via workplace health promotion on cardiometabolic risk needed evaluation.
Does a workplace health promotion program targeting diet quality and physical activity improve cardiometabolic risk in employees?

A workplace health promotion program targeting diet quality and physical activity significantly improves cardiometabolic risk factors such as waist circumference and lipid levels.
Workplace programs were associated with cardiometabolic gains; leaves open confirmation via randomized trials in employees.
The American Heart Association criteria for cardiovascular health include overall diet quality (DQ). The present study evaluated the effect of a workplace health promotion program targeting DQ and physical activity on features of cardiometabolic risk (CMR). Before and after the 3-month intervention, 2260 employees (1462 men and 798 women) completed a health and fitness evaluation including assessment of DQ using a validated food-based questionnaire. After the 3-month lifestyle modification program, DQ increased significantly in both sexes (p < 0.0001) as well as physical activity level (p < 0.0001). A reduction in waist circumference (p < 0.0001) and improved lipid levels were also observed. Significant associations were found between changes in DQ index and changes in CMR variables in both men (standardized regression coefficients ranged from −0.19 (95% confidence interval: −0.26 to −0.12) to −0.29 (95% confidence interval: −0.34 to −0.25)) and women (standardized regression coefficients ranged from −0.18 (95% confidence interval: −0.25 to −0.11) to −0.27 (95% confidence interval: −0.41 to −0.13)). Multiple linear regression analyses showed a significant contribution of changes in the DQ index to the variation in some CMR variables, independent from changes in physical activity level and cardiorespiratory fitness. This study provides evidence that targeting DQ at the workplace is relevant to improve cardiometabolic health.

Amil et al. (2021) conducted a cohort in Cardiometabolic risk (n=2,260). Workplace lifestyle modification program vs. Baseline (pre-intervention) was evaluated on Diet Quality (DQ) index (7 unit increase, p=<0.0001). A 3-month workplace lifestyle modification program significantly increased diet quality by 7 units (p<0.0001) and improved physical activity, waist circumference, and lipid levels in both men and women.
