Self-regulation and weight reduction in patients with type 2 diabetes: A pilot intervention study

Abstract Objective To evaluate the efficacy of a self-regulation (SR) weight reduction intervention on weight, body mass index (BMI), glycosylated hemoglobin (HbA1c) (primary outcomes), exercise, nutrition and quality of life (secondary outcomes). Methods A pilot intervention ( n = 53) based on SR-p...

Description
Summary:Abstract Objective To evaluate the efficacy of a self-regulation (SR) weight reduction intervention on weight, body mass index (BMI), glycosylated hemoglobin (HbA1c) (primary outcomes), exercise, nutrition and quality of life (secondary outcomes). Methods A pilot intervention ( n = 53) based on SR-principles consisted of a motivational interview, group sessions and a workbook and was evaluated against standard care with ( n = 38) and without a self-help manual ( n = 38). Subjects were overweight (BMI > 27) patients with type 2 diabetes (52% female) from a Dutch hospital (mean age 58.14, S.D. = 8.86). Results No differences in the outcomes were found between the intervention and control groups at 3 (T2) or 6 (T3) months. However, results at T2 and T3 revealed that patients with higher SR-skills scores had lower HbA1c levels than patients with lower scores. Conclusion The SR-intervention did not significantly influence the outcomes. This apparent lack of effect might, however, partly be due to high attrition rates in all treatment groups. SR-skills were positively related to changes in HbA1c-levels. Practice implications Improving SR-skills of overweight diabetes type 2 patients may improve their glycemic control. Patients who are ‘external regulators’ may however profit more from directive than from SR-interventions.
