Table 6 Definition of obesity and systemic examination

Al – Zahrani et al. 2012 [8]

Normal-weight: BMI: 18.5 to < 25 kg/m²

Obese: BMI ≥ 30 kg/m²

Weight in kilograms and height in meters were measured;

BMI: (weight/height² [kg/m²])

Bouaziz et al. 2015 [28]

Normal-weight: BMI ≥ 18.5 kg/m² and ≤ 25 kg/m²

Obese: BMI ≥ 30 kg/m²

Weight (kg), height (m), waist/hip circumferences (cm)

weight was obtained using a calibrated scale,,

height was measured using a measuring board,

BMI: (weight/height² [kg/m²]),

waist measurements were taken at the level of the umbilicus (cm)

hip measurements were taken at the greatest circumference with a measuring tape,

WHR: ratio of waist to hip circumference

Duzagac et al. 2015 [29]

Normal-weight (CPNW): n.r.

Obese (CPO): BMI ≥ 30 % and WHR > 0.95 for males and 0,80 for females

One trained examiner performed all anthropometric measurements:

weight (kg), height (m), waist (cm), hip (cm),

BMI: (weight/height² [kg/m²]),

WHR: ratio of waist to hip circumference,

anthropometric measurements were repeated before the final follow-up visit to assess

whether there was any change in BMI or WHR

Eldin et al. 2013 [30]

Overweight: BMI: 25-29.9 kg/m²

Obese: BMI ≥ 30 kg/m²

According to the WHO (3)

n.r.

Gonçalves et al. 2015 [31]

Without obesity: BMI 20-29.9 kg/m² and

WHR < 0.85 for females and < 0.9 for males

With obesity: BMI ≥ 30 kg/m² and < 40 kg/m² and

WHR ≥ 0.85 for females and WHR ≥ 0.9 for males

BMI: (weight/height² [kg/m²])

WHR: ratio of waist to hip circumference

Non-obese: BMI: 20-24.9 kg/m2 and WHR below that determined for obesity (i.e. WHR < 0.85 for women and

WHR < 0.90 for men) (World Health Organization 2008)

Obese: BMI ≥ 30 and < 40 kg/m2 and concomitant WHR

≥0.85 for women and WHR ≥ 0.90 for men.

One trained examiner performed

all anthropometric measurements:

weight (kg), height (m), waist (cm) and

hip circumferences (cm)

BMI: (weight/height² [kg/m²]),

WHR: ratio of waist to hip circumference,

anthropometric measurements were reassessed at all follow-up visits to verify that the patients did not change their obese or non-obese status during the course of the study

Lakkis et al. 2011 [33]

Control: obese (BMI ≥ 30 kg/m²)

Did not have the bariatric surgery nor did they lose weight to serve as a control group

Surgery: obese (BMI ≥ 30 kg/m²) and

≥ 40 % loss of their excess weight at ≥ 6 months after bariatric surgery

BMI: (weight/height² [kg/m²])

Percentage of weight loss after BS

Suvan et al. 2014 [34]

Normal: BMI: 18.5-24.99 kg/m²

Overweight: BMI: 25-29.99 kg/m²

Obese: BMI ≥ 30 kg/m²

BMI: (weight/height² [kg/m²])

Based upon height and weight of the individual measured with a wall-mounted height measure and mechanical scales
