Obesity assessment

Prevalence of obesity, central obesity and the associated factors in urban population aged 20–70 years, in the north of Iran: a population‐based study and regression approach

“…In this study we have also determined the prevalence rate as well as the risk factors for central obesity. Since substantial evidences indicate that increased WC or waist to hip ratio (WHR) independently predict obesity associated comorbidities and mortality (4,12). In this study we determined central obesity based on WC criteria.…”

“…The demographic and lifestyle data, in particular, age, gender, marital status, marriage age, family history of obesity, educational level, occupation, occupational physical activities, the level of leisure time physical activities, the duration of exercise per week by hours, the number of children and the parity were collected with designed questionnaire. The diagnosis of obesity was confirmed by the WHO standard recommended method (11–13) in which a BMI 25–29.9 kg m −2 was regarded as overweight; BMI ≥ 30 kg m −2 as obesity. Central obesity was diagnosed on the base of WC with cut‐off points of WC > 88 cm for women and WC > 102 cm for men.…”

Post-Operative Obesity and Cachexia Are Risk Factors for Morbidity and Mortality After Heart Transplant: Multi-Institutional Study of Post-Operative Weight Change

“…Patients were divided into groups using cut-offs for categories of BMI (underweight, normal, overweight, obese) from the National Heart Lung and Blood Institute (NHLBI), National Institutes of Health (NIH). 2,18 The current cut-off scheme for BMI is different from the cut-off points used in our previous analyses on the impact of pre-transplant body weight on post-transplant morbidity and mortality. 11 The categories from our previous report were from the NHANES II study (based on statistical data from reference populations and risk of morbidity and mortality in men and women at that time).…”

“…18 -20 The reason we chose to use the current categorization of BMI is that, based on more recent epidemiologic data, an expert panel of the NHLBI found a modest risk for increased mortality at a BMI of Ͼ25 kg/m 2 and a markedly increased risk at a BMI of Ͼ30 kg/m 2 , which are lower cut-offs for overweight and obesity than cut-offs used in our previous report. 2,18 Furthermore, the NHLBI sub-classified obesity as follows: Class I (BMI 30.0 to 34.9 kg/m 2 ); Class II (BMI 35 to 39.9 kg/m 2 ); and Class III (BMI Ն 40.0 kg/m 2 ). In this study, 37% of patients were overweight, and 17% were obese immediately before heart transplantation (Table 1).…”

Moderate intensity exercise improves heart rate variability in obese adults with type 2 diabetes

“…Each participant underwent the measurement of his weight and height recorded while wearing light indoor clothes but no shoes. Body mass index (BMI) was calculated as weight in kilograms/height in meters squared as a measure of overall adiposity whereas waist circumference (midway between the lower rib margin and the top of the iliac crest) was considered a measure of central or abdominal adiposity 16 . Blood pressure was measured using standard protocol.…”
