Abstract
Management of type 2 diabetes includes medications that can unintentionally increase obesity and insulin resistance. This unblinded, single-centre, randomised controlled trial focused on rural Australian adults with type 2 diabetes (aged 18-75 and body mass index [BMI] >30 kg/m2), measuring the effectiveness of a tailored interdisciplinary obesity care approach compared with usual diabetes care. Led by a nurse practitioner with allied health support (dietitian ± psychologist and physiotherapist), the bariatric treatment involved reducing weight-gaining medications, a 500-calories/day deficit, an unsupervised exercise program emphasising movement/strength and psychotherapy, 3-monthly to 24-months with support phone calls at weeks 2, 4, 8 and 10. Outcomes from the 224 (113 intervention/111 control) participants were differences in biomedical and physical markers within- and between-groups estimated using multivariate mixed-effects linear regression between recruitment and 6-monthly follow-ups. Greater change occurred in intervention compared with control groups at 12 and 24 months in mean: body weight (-5.9 kg [95% confidence interval, CI: -8.53, -3.23] and -9.0 kg [95% CI: -13.2, -4.77]); BMI (-2.03 kg/m2 [95% CI: -2.92, -1.15] and -3.51 kg/m2 [95% CI: -4.93, -2.08]); and glycated haemoglobin (-0.26% [95% CI: -0.69%, 0.18%] and -0.63% [95% CI: -1.17%, 0.08%]). The control group showed a significant increase in mean leptin level, resulting in a between-group difference (-27.1 [95% CI: -42.7, -11.5]). Lipids and blood pressure differences were inconclusive, while exploratory analysis showed greater decline in estimated glomerular filtration rate in the control group. The interdisciplinary obesity approach, compared with usual diabetes care, resulted in sustained weight loss and improved diabetes control over 2 years. Trial registration number: ACTRN12622000240741.
