Abstract

BACKGROUND: Workplace barriers to physical activity (PA) and sedentary work contribute to obesity. Workplace lifestyle interventions are needed to reduce sedentary behavior. OBJECTIVE: The study evaluates the effects of a self-monitoring PA protocol plus diet on general health of workers with obesity. METHODS: Thirty-nine workers affected by obesity were enrolled in this pilot intervention study. Monthly and daily PA diary, six-minute walking test (6MWT), Short Form-36 health survey (SF-36), and Global Physical Activity Questionnaire (GPAQ) results were evaluated prior (T0) and at the end of the study (T1). A personalized low-calorie diet based on the Mediterranean diet model was also implemented. Participants followed the protocol from one to three months depending on the date of recruitment. RESULTS: Significant improvements in SF36 and GPAQ scores were recorded, along with reductions in sedentary activity, weight, and BMI (p < 0.001). 6MWT significantly increased from 462.5 [412.5–500] m at T0 to 500 [462.5–550] m at T1 (p < 0.001). A multiple linear regression analysis to investigate the impact of selected covariates (PA, body weight reduction, and sedentary time) on the 6MWT was significant in men. CONCLUSIONS: PA self-monitoring protocols and diets are effective and sustainable for workplace interventions. PA should be part of daily medical practice and occupational physicians should encourage behavioral changes in workers.
