Impact of Overweight, Obesity, and Lifestyle Changes on Work Performance and Well-Being in Medical Residents (OBESIT-A)
Observational Study on the Impact of Overweight and Obesity and Lifestyle Changes on Work Performance and Well-being
The goal of this observational study is to evaluate the impact of overweight, obesity, and lifestyle changes on work performance, work ability, quality of life, and overall well-being in medical residents working in hospital and university settings. The main questions it aims to answer are:
- Is overweight and obesity associated with reduced work productivity, including absenteeism, presenteeism, and perceived work ability?
- Is overweight and obesity associated with lower health-related quality of life, psychological well-being, and worker well-being?
- Do lifestyle improvements and clinically significant weight loss over a 12-month period lead to measurable improvements in work productivity, work ability, quality of life, and well-being?
- Do changes in physical health, mental health, and organizational factors mediate the relationship between weight loss and occupational outcomes? Participants will undergo assessments at baseline and after 12 months of follow-up. Researchers will evaluate associations between body weight status, health outcomes, and occupational performance over time.
Participants will: Attend occupational health surveillance visits at baseline and at 12 months. Undergo anthropometric measurements, including body mass index (BMI), waist circumference, and blood pressure assessment.
Provide blood samples for routine laboratory evaluation, including metabolic, cardiovascular, inflammatory, and hematological parameters.
Complete validated questionnaires assessing health-related quality of life (SF-12), work ability (Work Ability Index), work productivity and activity impairment (WPAI), fatigue (Fatigue Severity Scale), psychological well-being (PGWBI), mental health (DASS-21), worker well-being (NIOSH WellBQ), and resilience (CD-RISC). Provide information on sociodemographic characteristics, lifestyle habits, medical history, occupational characteristics, and work-related exposures.
The study will estimate the prevalence of overweight and obesity in a cohort of medical residents and investigate their association with occupational and health-related outcomes. Longitudinal analyses will examine whether changes in lifestyle behaviors and body weight are associated with changes in productivity, absenteeism, presenteeism, work ability, quality of life, and well-being over a 12-month observation period. The study will also explore potential mechanisms linking weight status and occupational outcomes, including physical health, psychological health, and organizational factors.

Medical Residents Cohort
Male and female medical residents undergoing occupational health surveillance, evaluated for body weight status, lifestyle factors, quality of life, well-being, work ability, and work productivity at baseline and after 12 months of follow-up.
|
Participants will not receive any study-specific intervention.
The study is observational and evaluates body weight status, including normal weight, overweight, and obesity, as well as changes in lifestyle behaviors and body weight over a 12-month follow-up period.
Associations between these factors and work productivity, work ability, quality of life, psychological well-being, and overall worker well-being will be assessed through clinical evaluations, laboratory testing, and validated questionnaires.

Prevalence of Overweight and Obesity
Časové okno: Baseline
|
Prevalence of overweight and obesity among medical residents, assessed using standardized anthropometric measurements including body mass index (BMI) and waist circumference.
Participants will be classified according to BMI categories (normal weight, overweight, and obesity) to estimate the burden of excess body weight in the study population.

Change in Work Productivity and Activity Impairment From Baseline to 12 Months
Časové okno: Baseline and 12 months
|
Change in work productivity and activity impairment will be assessed using the Work Productivity and Activity Impairment Questionnaire (WPAI).
Outcomes will be reported as percentages from 0% to 100%, including absenteeism, presenteeism, overall work productivity impairment, and activity impairment.
Higher percentages indicate greater impairment and worse productivity.
