Comprehensive nutrition and lifestyle education improves weight loss and physical activity in Hispanic Americans following gastric bypass surgery: a randomized controlled trial.
BACKGROUND As morbid obesity increasingly affects Hispanic Americans , the incidence of bariatric procedures among this population is rising . Despite this , prospect i ve research on the effects of comprehensive postoperative education-centered interventions on weight loss and physical activity focused on Hispanic Americans is lacking . OBJECTIVE To examine whether a comprehensive nutrition education and behavior modification intervention improves weight loss and physical activity in Hispanic Americans with obesity following Roux-en-Y gastric bypass surgery ( RYGB ) . METHODS A prospect i ve r and omized-controlled trial was conducted between November 2008 and April 2010 . At 6 months following RYGB , 144 Hispanic Americans with obesity were r and omly assigned to a comprehensive nutrition and lifestyle educational intervention ( n=72 ) or a noncomprehensive approach ( comparison group n=72 ) . Those in the comprehensive group received education sessions every other week for 6 weeks in small groups and frequent contact with a registered dietitian . Those in the comparison group received brief , printed healthy lifestyle guidelines . Patients were reassessed at 12 months following surgery . Main outcome measures were excess weight loss and physical activity changes over time . Statistical analyses used t test , ? ( 2 ) test , Wilcoxon signed rank , Mann-Whitney U test , and intent-to-treat analysis , significance P<0.05 . RESULTS Participants ( mean age 44.5 ± 13.5 years ) were mainly Cuban-born women ( 83.3 % ) .  Mean preoperative excess weight and body mass index ( calculated as kg/m(2 ) ) were 72.20 ± 27.81 kg and 49.26 ± 9.06 , respectively . At 12 months following surgery , both groups lost weight significantly , but comprehensive group participants experienced greater excess weight loss ( 80 % vs 64 % from preoperative excess weight ; P<0.001 ) and greater body mass index reduction ( 6.48 ± 4.37 vs 3.63 ± 3.41 ; P<0.001 ) than comparison group participants . Comprehensive group participants were significantly more involved in physical activity ( + 14 min/wk vs ? 4 min/wk ; P<0.001 ) than comparison group participants . Mean protein intake was significantly lower in the comparison group than that in the comprehensive group ( P<0.024 ) . CONCLUSIONS Findings support the importance of comprehensive nutrition education for achieving more effective weight reduction in Hispanic Americans following RYGB
