“…Studies largely had body weight or BMI as the main outcome. Most of the included studies were targeted at low-SES adults (n = 67 43,65,66,103,128,132,134-137,140,141,143-148-150,152-160,164-171,174,176,178-185,197-199,200-217,223-225,230,231 ) although there was a reasonable number of studies that examined differential intervention effects by SES (n = 36 127,[129][130][131][138][139][140][141][142][143][144][145][146][161][162][163]172,173,175,[186][187][188][189][190][191][192][193][194][195][196]218,219,221,222 ). There were some high-quality studies (n = 23 128-131, 133,135,136,140,150,157,167,176,183,186,189,197-200,210,211,225,230 ) but the majority were only of low (n = 47 43,65,66,127,138,139,141-144, 146-149,152,153,155,156,159,161-166,169-173,178,180,188,193,195,196,201,204-206,208,213,214,218,223,224 ) or moderate (n = 33 Did not meet inclusion criteria (n = 3043) Individual (n = 31) (33 studies)…”
