Special Issue Information

Dear Colleagues,

Diabetes is a significant health and social problem worldwide, leading to serious complications, such as cardiovascular disease, diabetic foot, kidney disease, retinopathy, liver disease, and increased mortality and disability. An unbalanced diet and low physical activity are the most important risk factors for diabetes, in addition to genetics, making both dietary interventions and regular physical activity necessary for its prevention and proper management. However, patients should follow regular patient education sessions if they would like to see lasting improvements in their lifestyle and change their knowledge, attitudes, and skills regarding diabetes. Patient education, dietary interventions, and regular physical activity are now considered powerful therapeutic tools to improve the control of both diabetes and its comorbidities, such as hypertension, dyslipidemia, obesity, and hyperuricemia, and reduce the risk of complications.

This Special Issue aims to gather current knowledge on the effect of patient education, dietary interventions, and physical activity not only on the prevention and management of diabetes, but also its complications. We welcome original research and reviews (including systematic reviews and meta-analyses) providing useful information for diabetologists, endocrinologists, internists, nurses, nutritionists, trainers, and dieticians, as well as inspiring further innovative research.

Background. It is unclear if dietary education may increase adherence to the Mediterranean diet (MD). Study aim. We estimated the effect of dietary counseling on nutritional knowledge and adherence to MD in T2D adult patients. Methods. T2D patients who attended the Diabetology Center of the Grande Ospedale Metropolitano Niguarda were recruited (April to September 2019) and categorized into two groups: the intervention group (IG), receiving a 2.5-h education, and the control group (CG). The Moynihan questionnaire and the Mediterranean Diet Adherence Assessment Questionnaire (MDAAQ) were administered to estimate the overall knowledge and adherence to MD at baseline (T0), 1 week (T1), and 1 month (T2) later. Results. Seventy-two individuals (69.5 ± 8.6 years old) were included in the IG, and 52 (67.7 ± 9.2 years old) were included in the CG. All patients had sufficient dietary knowledge and intermediate adherence to MD at baseline. Those assigned to the IG showed a significant reduction in the Moynihan score from T0 (24.9 ± 2.6) to T1 (20.3 ± 1.8; p < 0.001) and T2 (20.4 ± 2.2; p < 0.001). CG had the same Moynihan score as IG individuals at T0 (24.8 ± 1.8), but their dietary knowledge was unchanged at T1 and T2 (24.9 ± 1.8). MD adherence was similar at each time in the IG, with a MDAAQ score of 4.4 ± 1.7 (T0), 5.1 ± 1.7 (T1), and 5.3 ± 1.8 (T2), and in the CG (T0: 5.1 ± 1.7; T1: 5 ± 1.5; T2: 5.1 ± 1.5). Discussion and Conclusions. The 2.5-h dietary counseling session improves dietary knowledge, but it is not enough to improve adherence to MD. Full article

Interventions for primary prevention are crucial in tackling type 2 diabetes (T2D) by offering a structured approach to implementing lifestyle modifications, such as community-based programs. The aim of this study was to demonstrate the effectiveness of primary prevention interventions in preventing or delaying the onset of T2D in the 28 EU member states (EU-28). The present systematic review is registered on PROSPERO (CRD42020219994), and it followed the PRISMA guidelines. Eligibility criteria comprised original interventional studies reporting incidence of T2D in member states of the EU-28. A total of 23,437 records were initially retrieved, of which 16 met the eligibility criteria for inclusion. These interventional studies, published between 2003 and 2021, provided data from Spain, the UK, Finland, the Netherlands, and Denmark. Thirteen studies were of low quality, two were moderate, and one was high-quality. Three studies focused solely on dietary interventions, twelve studies combined diet, physical activity, and lifestyle counseling, and one study applied repeated health checks with personalized feedback and lifestyle advice. Overall, 10 studies reported a significant reduction in T2D incidence exclusively among high-risk individuals following the interventions with HR: 0.4 (95% CI: 0.3–0.7) to 0.75 (95% CI: 0.58–0.96). Only a few studies reported that primary lifestyle interventions decreased T2D risk, thus limiting generalizability. While lifestyle improvements were noted on high-risk groups, significant risk reduction among healthy individuals was not observed. Multicomponent interventions combining dietary modifications, physical activity, and personalized lifestyle counseling were the most effective in reducing the incidence of T2D among high-risk populations in the EU-28.
