Abstract
BackgroundThere is a worldwide trend among the general population including health workers to become more overweight and obese. Such obesity can reduce work ability as manifested through sickness absenteeism. The aim of this study was to describe the obesity among health workers in a private hospital in central South Africa, as measured by the body mass index (BMI) as well as the association of obesity and sickness absenteeism.MethodsA cohort analytical study was conducted to describe changes in the BMI of employed health workers as well as the association of obesity and absenteeism in a private hospital in South Africa. The BMI measurement on employment, a repeat BMI at the time of the study as well as the sick leave days taken since employment of all health workers who had been employed for more than one year were analysed.ResultsFull time employees (n = 344) participated in the study of whom 33.7% were obese; 26.2% were overweight; 36.3% had normal weight and 3.7% were underweight at employment. On repeat BMI done in February 2016, 43.0% were obese; 27.6% were overweight; 28.2% had normal weight and 1.2% were underweight. There was no difference in the amount of sick leaves taken between the normal weight, overweight and obese groups.ConclusionA trend among health workers to change to a higher BMI category during employment is concerning, but there was no statistically significant association between the different weight groups and sickness absenteeism. The negative impact of obesity on the productivity of workers cannot be ignored.
Highlights
Obesity can be considered a disease caused by an unhealthy lifestyle that has reached epidemic proportions.[1]
They found that a 10% increase in the openness index was associated with an increase in adult obesity prevalence of 1.44% in Asia, but a less strong relationship was found in North American and African countries with a 10% increase in the openness index associated with an increase in adult obesity prevalence of 0.41% and 0.21%, respectively
The results indicated that only 28.2% of health workers in the private hospital had a normal body mass index (BMI) at the time of the study in 2016
Summary
Obesity can be considered a disease caused by an unhealthy lifestyle that has reached epidemic proportions.[1] The statement was confirmed by the World Health Organization (WHO) when it declared obesity as the largest non-communicable disease in adults, which is increasingly turning into a more serious problem than malnutrition.[2] An et al.[3] conducted a study across 175 countries and found that the global average adult obesity prevalence steadily increased from 5% in 1975 to 19% in 2016. The aim of this study was to describe the obesity among health workers in a private hospital in central South Africa, as measured by the body mass index (BMI) as well as the association of obesity and sickness absenteeism
