Summary, in English

Clinically relevant weight loss is achievable through lifestyle modification, but unintentional weight regain is common. We investigated whether recently discovered genetic variants affect weight loss and/or weight regain during behavioral intervention. Participants at high-risk of (Diabetes Prevention Program [DPP]; N=917/907 intervention/comparison) or with (Look AHEAD; N=2,014/1,892 intervention/comparison) type 2 diabetes were from two parallel arm (lifestyle vs. comparison) randomized controlled trials. The associations of 91 established obesity-predisposing loci with weight loss across 4 years, and with weight regain across years-2-4 after a minimum of 3% weight loss, were tested. Each copy of the minor G allele of MTIF3 rs1885988 was consistently associated with greater weight loss following lifestyle intervention over 4-years across DPP and LA. No such effect was observed across comparison arms, leading to a nominally significant SNP × treatment interaction (P=4.3×10(-3)). However, this effect was not significant at a study-wise significance level (Bonferroni threshold P<5·8×10(-4)). Most obesity-predisposing gene variants were not associated with weight loss or regain within the DPP and Look AHEAD trials, directly or via interactions with lifestyle.
