Quantitative assessment of dietary intake in adults with Type 1 diabetes following flexible insulin therapy education with an active promotion of dietary freedom

Abstract

Clinical practice guidelines for diabetes include dietary guidelines to address the increased risk of cardiovascular disease. Aims: To identify impact of flexible insulin education with an active promotion of dietary freedom on energy and macronutrient intake and achievement of nutrient recommendations in adults with Type 1 diabetes. Methods: Dietary assessment was performed prior to and 12 months following flexible insulin education. Nutrient intake and the proportion achieving the European Association for the Study of Diabetes (EASD) nutrient guidelines were compared at baseline and post course. Results: Dietary data were available for 46 participants. Post course reductions were seen in median [IQR] energy kcal/d (1799 [1521-1931] to 1592 [1378-1940], p = 0.002), fibre g/1000 kcal (14 [12-16] to 13 [11-15], p = 0.047), protein g/day (89 ([78-108] to 82 [74-93], p = 0.001) and carbohydrate g/day (198 [172-330] to 162 [143-204], p = <0.001). The proportion experiencing at least 1 severe hypoglycaemia event over 12 months was significantly reduced (χ2 = 7.7, p = 0.006) from baseline (n = 13, 26%) to post course (n = 3, 6%). Achievement of EASD guidelines was poor and did not change post course. Conclusions: Flexible insulin education with an active promotion of dietary freedom does not appear to 'worsen' the achievement of EASD nutrition guidelines in adults with Type 1 diabetes. On the contrary, the dietary changes observed were reductions in energy, carbohydrate and protein intake. Flexible insulin education may offer benefits in enabling reduced energy intake without increasing hypoglycaemia.L6103105652016-05-20 <br />2016-05-26 <br />
