Garcia‐Morales 2006	Waist circumference ‐ measured with a flexible tape between the highest point of the iliac crest and the lowest part of the costal margin at the midaxillary line (no reference) (IO)	A detailed questionnaire on food consumption was completed at the beginning and end of the trial (no reference) (SO)	N/I	N/I
Godoy‐Matos 2005	Waist circumference ‐ measured at the minimal circumference between iliac crest and last rib edge. Hip circumference assessed at the greatest circumference through the major trochanters (no reference) (IO)	N/I	N/I	N/I
Kendall 2013	Waist‐to‐hip ratio (no reference) (IO)	3 previously validated questionnaires (food frequency, diet and eating behaviour, and physical activity) were completed by each child at the start and end of the trial. No results presented (SO)	N/I	N/I
Maahs 2006	BIA	Diet records recorded before enrolment and at 3 and 6 months. No reference or results provided (SO)	N/I	N/I
Mauras 2012	Waist circumference measured at umbilicus (no reference). Intrahepatic fat content measured using fast MRI. References: Fishbein 2001; Fishbein 2003. Body composition was measured DEXA. Also measured waist‐to‐height ratio (no reference) (IO)	N/I	N/I	N/I

Ozkan 2004	N/I	N/I	N/I	N/I
Prado 2012	Waist circumference ‐ measured with a central flexible tape, corresponding to the perimeter less between the iliac crest and the bottom edge last rib, then exhale with arms relaxed on both sides (no reference) (IO)	N/I	N/I	N/I
Rezvanian 2010	Waist circumference ‐ measured at a point midway between the lower border of the rib cage and the iliac crest at the end of normal expiration (no reference) (IO)	N/I	N/I	N/I
Srinivasan 2006	Raw waist circumference data not reported. Waist circumference was calculated from the mean of 3 measures at the level of the umbilicus (no reference). Waist circumference z scores calculated from recent multiracial American reference data (Fernandez 2004). Raw body composition data were not reported. DEXA scans also used. MRI whole‐body scans (IO)	N/I	N/I	N/I
Van Mil 2007	Body composition was assessed using a 4‐component reference model: total bodyweight = fat mass + total body water + total bone mineral content and remaining fat‐free mass (references: Fuller 1992; Van Marken Lichtenbelt 1999). To calculate this they used densitometry, deuterium dilution (Maastricht protocol) with labelled water test and DEXA (IO)	Physical activity level was estimated using an activity questionnaire. A 7‐day dietary record was given to each participant. Only the food quotient used in the assessment (respiratory exchange ratio to calculate TEE). Rest of the data not presented (IO, SO)	N/I	N/I
Wiegand 2010	Waist‐to‐hip ratio and body composition (BIA) were measured but no explanation to how and no results given (apart from saying they were not significant) (IO)	N/I	N/I	N/I
Wilson 2010	Abdominal CT scans evaluated abdominal fat content and distribution (Borkan 1982). Whole body DEXA used to measure % body fat and lean body mass (von Scheven 2006). Waist circumference measured at the smallest circumference below the rib cage and above the umbilicus (Wang 2003) (IO)	N/I	N/I	N/I
Yanovski 2011	Abdominal and hip circumferences (assessed in triplicate) and triceps skinfold thickness. Whole‐body fat mass by DEXA and by air displacement plethysmography; and intra‐abdominal and subcutaneous abdominal adipose tissue by MRI at L2 to L3 and L4 to L5 (IO)	N/I	N/I	N/I
aIn addition to definition of endpoint measurement, description who measured the outcome (AO: adjudicated outcome measurement; IO: investigator‐assessed outcome measurement; SO: self‐reported outcome measurement). BIA: bioelectrical impedance analysis; CT: computed tomography; DEXA: dual‐energy X‐ray absorptiometry; MRI: magnetic resonance imaging; n: number of participants; N/I: not investigated; TEE: total energy expenditure.
