Assessment of Alimentación Normal con Ajuste de Insulina (ANAIS), a Spanish version of the DAFNE programme, in people...

To evaluate the effects of Alimentación Normal con Ajuste de Insulina (ANAIS), a group-based, therapeutic education programme for Type 1 diabetes based on a flexible insulin regimen adjusted to the individual's food intake.

Participants with Type 1 diabetes and HbA_1c levels of 53-86 mmol/mol (7-10%) were recruited from outpatient clinics at a tertiary care centre. They were randomized (using opaque, sealed envelopes, with a 2:1 treatment allocation ratio) to attend the training course immediately (immediate ANAIS; intervention group) or a year later (delayed ANAIS; control group). The main outcome was HbA_1c level at 1 year. Secondary outcomes included lipid levels, weight, hypoglycaemic events, insulin dose, treatment satisfaction, self-perceived dietary freedom, quality of life and participant-defined goals.

A total of 48 participants were assigned to the intervention group and 32 to the control group. Twelve months after completing the training, adjusted HbA_1c was not significantly different in the intervention group [64 ± 1.3 vs 68 ± 1.6 mmol/mol (8.0 ±0.1% vs 8.4 ±0.1%); P=0.081]. Treatment satisfaction was significantly higher in the intervention group, but no differences were found in hypoglycaemic events, weight, insulin dose or changes in dietary freedom. At 1 year after the intervention, 72% of the participants (vs 33% in the control group; P=0.046) reported exceeding their expectations regarding achievement of their main personal goal.

Promoting dietary freedom and empowering people with Type 1 diabetes through structured education programmes, such as ANAIS, improves treatment satisfaction and self-defined goals. No significant improvement in HbA_1c level was achieved.
