Annals of Behavioral Medicine

Abstract

Background

Intensive lifestyle intervention trials in type 2 diabetes contribute evidence on what can be achieved under optimal conditions, but are less informative for translation in applied settings.

Purpose

Living Well with Diabetes is a telephone-delivered weight loss intervention designed for real-world delivery.

Methods

This study is a randomized controlled trial of telephone counseling (n = 151) versus usual care (n = 151); 6-month primary outcomes of weight, physical activity, HbA1c; secondary diet outcomes; analysis was by adjusted generalized linear models.

Results

Relative to usual care, telephone counseling participants had small but significantly better weight loss [−1.12 % of initial body weight; 95 % confidence interval (CI) −1.92, −0.33 %]; physical activity [relative rate (RR) = 1.30; 95 % CI, 1.08, 1.57]; energy intake reduction (−0.63 MJ/day; 95 % CI, −1.01, −0.25); and diet quality (3.72 points; 95 % CI, 1.77, 5.68), with no intervention effect for HbA1c (RR = 0.99; 95 % CI, 0.96, 1.01).

Conclusions

Results are discussed in light of challenges to intervention delivery.
