Effectiveness of a weight loss intervention in postpartum women: results from a randomized controlled trial in primary health care.
BACKGROUND Reproduction has been identified as an important factor for long-term  weight gain among women . A previous efficacy trial has successfully produced postpartum weight loss ; however , the effectiveness of this intervention needs to be established . OBJECTIVE This study was design ed to evaluate the short- and long-term effectiveness of a diet behavior modification treatment to produce weight loss in postpartum women within the primary health care setting in Sweden . DESIGN During 2011 - 2014 , 110 women with a self-reported body mass index ( BMI ; in kg/m(2 ) ) of ≥27 at 6 - 15 wk postpartum were r and omly assigned to the diet behavior modification group ( D group ) or the control group ( C group ) . Women r and omly assigned to the D group ( n = 54 ) received a structured 12-wk diet behavior modification treatment by a dietitian and were instructed to gradually implement a diet plan based on the Nordic Nutrition Recommendations and to self-weigh ≥3 times/wk . Women r and omly assigned to the C group ( n = 56 ) were given a brochure on healthy eating . The primary outcome was change in body weight after 12 wk and 1 y. The retention rate was 91 % and 85 % at 12 wk and 1 y , respectively . RESULTS At baseline , women had a median ( 1st , 3rd quartile ) BMI of 31.0 ( 28.8 , 33.6 ) , and 84 % were breastfeeding . After 12 wk , median weight change in the D group was -6.1 kg ( -8.4 , -3.2 kg ) compared with -1.6 kg ( -3.5 , -0.4 kg ) in the C group ( P < 0.001 ) . The difference was maintained at the 1-y follow-up for the D group , -10.0 kg ( -11.7 , -5.9 kg ) compared with -4.3 kg ( -10.2 , -1.0 kg ) in the C group ( P = 0.004 ) . In addition , the D group reduced BMI , waist circumference , hip circumference , and body fat percentage more than did the C group at both 12 wk and 1 y ( all P < 0.05 ) . CONCLUSION A low-intensity diet treatment delivered by a dietitian within the primary health care setting can produce clinical ly relevant and sustainable weight loss in postpartum women with overweight and obesity . This trial was registered at clinical trials.gov as NCT01949558
