A 7-Month Multidisciplinary Healthy Lifestyle Intervention Effectively Improved Cardiometabolic Risk Profile of Firefighters

Abstract

Objective We investigated the effect of a 7-month healthy lifestyle intervention on cardiometabolic risk factors (CMRF) among male career military firefighters (FFs). Methods Forty-nine FFs participated in a 7-month workplace multiddisciplinary healthy lifestyle intervention designed to reduce CMRF through exercise, diet, and improved sleep. Medical assessments, accelerometry, and surveys at the beginning and end determined program effectiveness. Results At the end of the intervention period, there was a significant improvement in measures of body composition and blood glucose. The prevalence of hypertension also decreased significantly (P < 0.01). The 57% of participants who fully adhered to the program had significantly greater improvements across multiple CMRF. Participants increased their physical activity and improved their diet following the intervention. Conclusions This healthy lifestyle intervention was effective in changing behavior and lowering cardiometabolic risk among FFs.
