Brief summary

Many recent studies have shown that overweight and mildly obese individuals have marginally better outcomes compared to individuals with normal weight following surgery or even nonsurgical situations such as heart related problems. However, body mass index (BMI) is not an accurate measure of body fat composition. We therefore need a measure that can be used at the bedside as well as one that can accurately predict the body fat composition and hence the risk associated with surgery. This pilot study is a miniature version of a future multicentre prospective cohort study to assess if waist circumference is a predictor of postoperative major adverse outcomes after elective non-cardiac surgeries. If that is so, we would like to know if it is better predictor than the currently popular predictor, BMI. We are also testing if other measures like waist to hip ratio, neck circumference are equally useful predictors or not.
