Purpose To investigate morbidity associated with overweight and obesity in health personnel and compare the differences among work roles. Materials and methods This retrospective cohort study examined measurements obtained during employee medical checkups between 2007 and 2016 in a Taiwan medical center. BMI was used to define overweight (≥24 and <27 kg/m2) and obesity (≥27 kg/m2). Morbidity refers to prevalence, period incidence proportion, and incidence rate. Multivariable Cox model was used to estimate the HRs and 95% CI of the incidence proportion across work roles. Results Ten thousand six hundred fifty-one health personnel with 24,295 BMI measurements were recruited. Mean age was 33.4±10.7 years and 72.4% was female. In total, 1,992 (8.2%) health personnel were underweight, 13,568 (55.8%) had a normal BMI, 5,097 (21%) were overweight, and 3,638 (15%) were obese. Five thousand nine hundred one health personnel with 31,172 different interval-year arrangement combinations were obtained. The incidence proportion of overweight and obesity was 1,947 (6.2%) and 1,494 (4.8%), respectively. The incidence rate was 37/1,000 and 15/1,000 person-years, respectively. Compared with that in supporting staff, the HR of overweight in doctors, nurses, and allied health professionals was 0.93 (95% CI =0.73–1.18, P=0.553), 0.92 (95% CI =0.73–1.16, P=0.491), and 0.85 (95% CI =0.67–1.09, P=0.202), respectively. Similarly, the HR of obesity was 0.86 (95% CI =0.66–1.14, P=0.301), 0.89 (95% CI =0.67–1.18, P=0.430), and 0.84 (95% CI =0.63–1.13, P=0.248), respectively. Conclusion In health personnel, the prevalence of overweight and obesity was 21% and 15%, respectively. The incidence proportion was 6.2% and 4.8%, respectively. Morbidity across the four health work roles examined was not significantly different.
