Effects of Guided Reflection on Diabetes Self-Care: A Randomized Controlled Trial

SGLT2 inhibitor versus carbohydrate-restricted isocaloric diet: reprogramming substrate oxidation in type 2 diabetes

OBJECTIVE

Based on the whole-body energy metabolism and insulin action, the difference between increased excretion of carbohydrate in urine by SGLT2i and reduced same amount of oral carbohydrate intake are scarce. This study aimed to compare the effect of carbohydrate availability with reduced oral intake (carbohydrate-restricted isocaloric diet: CRIC diet) or lost in urine, as urinary glucosuria on sodium/glucose cotransporter-2 inhibitor (SGLT2i) treatment, focus on the insulin requirement and the macronutrient oxidation within insulin treated type 2 diabetes.

METHODS

This is randomized 3-arm open-label prospective study. Subjects treated with titrated basal-bolus insulin regimen subsequent to three diet regimens, control diet (CON), administration of canagliflozin 100 mg/day to CON (SGLT2i), or CRIC diet, with a week admission to the endocrinology ward followed by 12 weeks outpatients' management. The main outcome measures including the total insulin dose (TID) required to achieve euglycemia, fasting and postprandial energy expenditure (EE) and respiratory quotient (RQ) at 1-week and 12-week.

RESULTS

We enrolled 23 patients with type 2 diabetes (male/female: 14/9, age: 53.6 ± 14.2 years, body mass index: 26.9 ± 4.8 kg/m2, HbA1c: 12.5 ± 1.6%). The TID was similar with CON and SGLT2i at both 1 and 12-weeks. Although comparable net carbohydrate availability in SGLT2i and CRIC groups, the TID was significantly higher in the CRIC (p = 0.02) compare to the SGLT2i at both 1 and 12-weeks. Fasting EE was similar in all groups, postprandial EE was significantly elevated in the SGLT2i and CRIC groups compared to the CON group (p = 0.03 and 0.04). Compare to the CON, lower basal fasting RQ (p = 0.049) and decreased delta-RQ (postprandial RQ/fasting RQ) indicated continuous lipid substrate utilization in the SGLT2i (p = 0.04) and CRIC (p = 0.03) groups.

CONCLUSION

The CRIC diet resulted in a similar fasting and postprandial EE and substrate oxidation compared to the SGLT2i. The increased insulin requirement in the CRIC diet indicates that a relatively highly lipid and protein consumption, compared to the SGLT2i and CON, may influence insulin requirement.

Undertaking Healthy Nutrition Behaviors by Patients with Type 1 Diabetes as an Important Element of Self-Care

BACKGROUND

Self-control/self-care means the active participation of a diabetic patient in therapy. It involves making numerous decisions and undertaking actions independently. The primary activities under the patient's control include adherence to medication regimens and maintenance of a health-promoting lifestyle, especially a healthy diet. However, the sense of responsibility for one's own health, i.e., high sense of responsibility (HSR), is an important element in the treatment of diabetes and in undertaking pro-health behaviors. The study aimed at analyzing adherence to dietary recommendations in the context of HSR in patients with type 1 diabetes.

METHODS

The cross-sectional study was conducted on a group of 394 adults. The assessment of adherence to dietary recommendations was performed with the present authors' Diabetes Dietary Guidelines Adherence Index (DDGA Index). The measurement of HSR was performed with the standardized Sense of Responsibility for Health Scale (HSRS). The assessment of the multifactorial influence of independent variables on the DDGA Index, including the "responsibility for health" variable, was conducted with the use of a linear regression model.

RESULTS

The mean DDGA value was 18.68 (SD = 3.97). The patients significantly more often avoided unhealthy products than included recommended products into the diet at a required frequency. A positive correlation was demonstrated between HSR and adherence to dietary recommendations (β_std. = 0.43, p < 0.001).

CONCLUSIONS

The sense of responsibility for one's health plays a main role in adherence to dietary recommendations in diabetes. Our study showed that a higher sense of responsibility for health was associated with a higher level of adherence to dietary recommendations. Patients with a high sense of responsibility for one's health will be more involved in the therapeutic process, including adherence to dietary recommendations. Therefore, all education actions should comprise not only dietary knowledge transfer and shaping appropriate skills, but they should also strengthen the sense of responsibility for one's health.

Effects of self-care programs on the incidence of diabetes among adults with prediabetes: A systematic review and meta-analysis of randomised controlled trials

OBJECTIVES

To verify the effects of self-care programs among adults with prediabetes, to identify the preferable structure components and to summarise the core content components of self-care programs.

DESIGN

A systematic review and meta-analysis of randomised controlled trials.

METHODS

PubMed, Embase, Cochrane, CINAHL, PsycINFO, Wanfang, CNKI, Chinese Biomedical Database and Open Grey were searched for studies published from January 2002 to December, 2021. Meta-analysis was conducted to verify the effects of self-care programs on diabetes incidence. Subgroup analyses based on structure components were performed to contrast the effects. We made a critical analysis to generalise the core elements of content components. The study was reported according to PRISMA statement.

RESULTS

Totally, 15 studies were included in systematic review, of which 14 studies were eligible for meta-analysis. The results of meta-analysis showed the incidence of diabetes for prediabetic adults receiving self-care programs was significantly lower than those who received usual care (OR 0.58; 95% CI 0.46 to 0.73). The results of subgroup analyses based on delivery mode, intervention implementer, health education brochures provided, and follow-up duration showed statistically significant reduction in incidence compared with control group (p < .05). However, the differences of these pair-wise comparisons (face-to-face or remote, individual or interdisciplinary team, with or without brochures provided, ≤1 year or >1 year) were not statistically significant (p > .05). Three core content elements were generalised: cognitive education, behaviour guidance and psychological support.

CONCLUSIONS

Self-care programs can effectively delay the progression of prediabetes to diabetes. Regardless of the diversified structure components, self-care programs can achieve better effects on the diabetes incidence than usual care, while the optimal structure components still remain unknown. Cognitive education, behaviour guidance and psychological support are core elements for these programs.

RELEVANCE TO CLINICAL PRACTICE

More clinical trials with rigorous study design are needed to provide further evidence.

A Self-Report Measure of Diabetes Self-Management for Type 1 and Type 2 Diabetes: The Diabetes Self-Management Questionnaire-Revised (DSMQ-R) – Clinimetric Evidence From Five Studies

Aims

Measurement tools to evaluate self-management behavior are useful for diabetes research and clinical practice. The Diabetes Self-Management Questionnaire (DSMQ) was introduced in 2013 and has become a widely used tool. This article presents a revised and updated version, DSMQ-R, and evaluates its properties in assessing self-management practices in type 1 diabetes (T1D) and type 2 diabetes (T2D).

Methods

The DSMQ-R is a multidimensional questionnaire with 27 items regarding essential self-management practices for T1D and T2D (including diabetes-adjusted eating, glucose testing/monitoring, medication taking, physical activity and cooperation with the diabetes team). For the revised form, the original items were partially amended and the wording was updated; eleven items were newly added. The tool was applied as part of health-related surveys in five clinical studies (two cross-sectional, three prospective) including a total of 1,447 people with T1D and T2D. Using this data base, clinimetric properties were rigorously tested.

Results

The analyses showed high internal and retest reliability coefficients for the total scale and moderate to high coefficients for the subscales. Reliability coefficients for scales including the new items were consistently higher. Correlations with convergent criteria and related variables supported validity. Responsiveness was supported by significant short to medium term changes in prospective studies. Significant associations with glycemic outcomes were observed for DSMQ-R-assessed medication taking, glucose monitoring and eating behaviors.

Conclusions

The results support good clinimetric properties of the DSMQ-R. The tool can be useful for research and clinical practice and may facilitate the identification of improvable self-management practices in individuals.
