Effects of mindfulness-based intervention on glycemic control and psychological outcomes in people with diabetes: A systematic review and meta-analysis

Effectiveness of Nurse-Led Psychological Interventions on Diabetes Distress, Depression, and Glycemic Control in Individuals With Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis

PURPOSE

To explore the effect of nurse-led psychological interventions on diabetes distress, depression, and glycemic control in individuals with type 2 diabetes mellitus (T2DM).

METHOD

Seven databases were systematically searched. Outcome measures were diabetes distress, depression, and hemoglobin A1c (HbA1c) level. RoB 2.0 was used for risk of bias assessment. Data were synthesized using Review Manager 5.4 software.

RESULTS

Fourteen studies were included from 2,837 articles. Five studies pooled in the meta-analysis demonstrated reduction in diabetes distress (standard mean difference = -0.36, 95% confidence interval [-0.49, -0.24], p < 0.001), favoring nurse-led psychological interventions over controls. Effects of the interventions on depression and HbA1c level were inconsistent across studies.

CONCLUSION

Nurse-led psychological interventions demonstrated the effect of reducing diabetes distress and some promising benefits for depression and glycemic control. Integrating nurse-led psychological interventions into usual care will be beneficial for individuals with T2DM in the future.

Effect of psychological intervention on glycemic control in middle-aged and elderly patients with type 2 diabetes mellitus: A systematic review and meta-analysis

AIM

There is an ongoing debate regarding the influence of psychological interventions on glycemic control in middle-aged and elderly patients diagnosed with type 2 diabetes. To establish evidence-based medical support for the therapeutic application of these interventions, this meta-analysis seeks to assess the impact of psychological interventions on glycemic control in middle-aged and elderly individuals with type 2 diabetes.

METHODS

This study systematically searched six electronic databases for randomized controlled studies of psychological interventions applied to middle-aged and elderly patients with type 2 diabetes, and the search time frames were all from the time of database creation to the search period from the establishment to March 2023. Two evaluators independently screened the literature evaluated the included studies' risk of bias, and carried out a meta-analysis using the RevMan5.4 program.

RESULTS

A total of 7 studies with 728 participants complied with the eligibility criteria. Meta-analysis showed that glycated glucagon was reduced in the psychological intervention group compared to the control group (MD = -0.26, 95 %CI:-0.51,-0.01,p = 0.01) with a statistically significant difference (p < 0.05). and their sensitivity analyses all showed stable and credible results.

CONCLUSIONS

This review concludes that psychological interventions, when applied to middle-aged and elderly individuals with type 2 diabetes, proved to be more effective in reducing HbA1c levels compared to standard care. Nevertheless, further evidence-based research is essential to elucidate the specific types of psychological interventions that contribute to improved glycemic control outcomes in middle-aged and older adults with type 2 diabetes.

Effectiveness of Mindfulness-Based Interventions with Respect to Psychological and Biomedical Outcomes in Young People with Type 1 Diabetes: A Systematic Review

BACKGROUND

Type 1 diabetes is a chronic disease especially affecting young people. Mindfulness-based psychological interventions might reduce emotional symptoms post-diagnosis, but the evidence is limited.

OBJECTIVES

This systematic review aimed to evaluate the effectiveness of mindfulness interventions on psychological well-being and biomedical variables in young people with type 1 diabetes.

METHODS

A systematic review of trials was conducted that involved a bibliographic search in electronic databases (Web of Science, MEDLINE, SciELO, Scopus, PsycINFO, and Cochrane Library) considering studies published between 2013 and 2024.

RESULTS

A total of 434 records were identified, of which 252 underwent selection according to title and abstract, leaving 32 that were evaluated for eligibility and 7 included in this review. From Google Scholar, six more studies were identified and evaluated, and two were selected. Finally, nine studies were subjected to full reading and a detailed analysis of the inclusion criteria. A total of 66.6% of the studies were evaluated as having a methodological quality of moderate or optimal, but the samples analysed tended to be small, and only two articles carried out short-term follow-up evaluations.

CONCLUSIONS

Mindfulness-based interventions, upon reviewing the preliminary results, may be posited as a viable strategy to enhance psychological (anxiety, diabetes distress, perceived stress, depression, self-efficacy, psychological well-being, and quality of life) and biomedical outcomes (glycaemic control, blood glucose levels, and diastolic blood pressure) for type 1 diabetes in young people. Although promising, further research is required to improve the quality, methodology, and design of studies.

Investigating the Impact of Ashwagandha and Meditation on Stress Induced Obesogenic Eating Behaviours

Obesity has been identified as a rapidly rising pandemic within the developed world, potentially increasing the risks of type 2 diabetes and cardiovascular disease. Various studies have identified a positive association between stress, elevated cortisol levels and obesity. Mechanisms of the stress response lead to hyperpalatable food preference and increased appetite through the activation of the HPA axis, elevated cortisol and the resulting interactions with the dopaminergic system, neuropeptide Y, ghrelin, leptin and insulin. The methodology of this review involved a Systematic Search of the Literature with a Critical Appraisal of papers considering ashwagandha, mediation and mindfulness in relation to mechanisms of the stress response. It incorporated 12 searches yielding 330 hits. A total of 51 studies met the inclusion criteria and were critically appraised with ARRIVE, SIGN50 and Strobe checklists. Data from the 51 studies was extracted, coded into key themes and summarized in a narrative analysis. Thematic analysis identified 4 key themes related to ashwagandha and 2 key themes related to meditation. Results provide an overview of evidence assessing the efficacy of ashwagandha and meditation in relation to weight loss interventions by supporting the stress response and the pathways highlighted. Results of Clinical studies indicate that ashwagandha supports weight loss through reduced stress, cortisol and food cravings. Pre-clinical studies also suggest that ashwagandha possesses the capacity to regulate food intake by improving leptin and insulin sensitivity and reducing addictive behaviors through dopamine regulation. Clinical studies on meditation indicate it may enhance a weight loss protocol by reducing the stress response, cortisol release and blood glucose and improving eating behaviors.

The effectiveness of mindfulness-based cognitive therapy during poststroke rehabilitation: a randomized controlled trial

Stroke can have a range of physical, psychological, cognitive, and social impacts that are challenging for survivors. This study aimed to evaluate the efficacy of a group-based mindfulness intervention integrated into an inpatient rehabilitation program compared to standard care. A single-center, randomized, controlled trial was conducted in 93 poststroke patients. The intervention group received 6-weeks of mindfulness-based cognitive therapy (MBCT) and standard care; the control group received standard care. Primary outcomes were depression and trait anxiety; secondary outcomes were trait mindfulness and attention. Participants completed questionnaires at baseline, and postintervention (6 weeks). Mixed-effect model repeated measures analysis of variance was conducted between groups and across time. A total of 80 participants (intervention n  = 43; standard care n  = 37) were included in the postintervention analysis. There were no statistically significant differences in the primary outcomes between the groups over time. An improvement was found, however, on the trait mindfulness observing subscale in favor of the intervention group. Eight sessions of MBCT integrated into an inpatient stroke rehabilitation program over 6 weeks was not effective in improving depression and anxiety compared to standard care. Lack of follow-up and low to moderate pathological symptoms at baseline may have limited the effectiveness of this intervention.

Effectiveness of acceptance and commitment therapy in people with type 2 diabetes mellitus: A systematic review and meta-analysis

BACKGROUND

Acceptance and commitment therapy (ACT) is a psychotherapy technique, which promotes psychological flexibility and enables patients to change behaviors based on value-directed goals. However, the beneficial effects of ACT on glycemic control, self-care behaviors, acceptance of diabetes, self-efficacy, and psychological burden are still unclear among patients with type 2 diabetes mellitus (T2DM).

AIMS

This study aimed to systematically synthesize scientific evidence to determine the effectiveness of ACT among patients with T2DM on glycemic control, self-care behaviors, acceptance of diabetes, self-efficacy, and psychological burden and identify the optimal characteristics of effective interventions.

METHODS

Nine electronic databases were searched to identify eligible studies of randomized controlled trials from inception to June 2023. Two reviewers independently assessed the study eligibility, extracted the data, and performed the quality appraisal using the Cochrane Risk of Bias 2 Tool. The meta-analysis was conducted using Review Manager 5.3. The certainty of the evidence was rated using the Grading of Recommendations Assessment, Development, and Evaluation system.

RESULTS

Ten studies involving 712 participants were included. ACT demonstrated significant improvements on patients' glycemic control (mean difference [MD]: 0.95%; p < .001), self-care behaviors (MD: 1.86; p = .03), diabetes acceptance (MD: 7.80; p < .001), self-efficacy (standardized mean difference [SMD]: 1.04; p < .001), anxiety (SMD: -1.15; p = .006), and depression (SMD: -1.10; p = .04). However, favorable but nonsignificant improvements were found in diabetes distress. Subgroup analyses demonstrated that ACT offered more than five sessions using individualized format, with theoretical underpinnings and professional input from multidisciplinary therapists are recommended to yield better results on glycemic control and self-care behaviors.

LINKING EVIDENCE TO ACTION

Acceptance and commitment therapy could generate beneficial effectiveness on glycemic control, self-care behaviors, acceptance of diabetes, self-efficacy, anxiety, and depression among patients with T2DM. Large-scale trials with rigorous design and representative samples are warranted to strengthen the current evidence.

Mindfulness and self-regulation intervention for improved self-neglect and self-regulation in diabetic older adults

The current study aimed to assess the impact of combined interventions including mindfulness and self-regulation on self-neglect and self-regulation among Iranian older adults with type 2 diabetes. This was a three-arm cluster randomized controlled trial study conducted among 135 older diabetic patients in Shiraz, Iran. Three urban healthcare centers (clusters) were randomly assigned to three study groups. The intervention groups received either a Self-Regulation-based Intervention Program (SRIP) or a Combined Mindfulness and Self-Regulation Intervention Program (CMSRIP), while the control group received routine care and COVID-19 prevention training. These training programs, which consisted of text and video-based content, were conducted over 24 weeks using WhatsApp as a mobile-based communication platform. Outcomes were measured using the Elder Self-Neglect Scale and Short-Form Self-Regulation Questionnaire at baseline, week 4, and week 16 post-intervention, with data analysis conducted using SPSS 20 software. The CMSRIP led to significantly greater improvement in the score of self-regulation (χ2 = 73.23, P-Value =  < .001) and a reduction in the score of self-neglect (χ2 = 62.97, P-Value =  < .001) at both 4 weeks and 16 weeks after education compared to SRIP. In the control group, there was also a slight improvement. Improvement of self-regulation and reduction of self-neglect in all three groups were less in week 16 than in week 4. Nevertheless, the changes in the intervention groups were significantly better than the control group. This study confirmed a combination of mindfulness-based intervention and self-regulation intervention can effectively improve self-neglect and self-regulation behavior in older patients with type 2 diabetes.Trial registration: This trial (ISRCTN77260130) was retrospectively registered on 28/09/2021.

Significance of non-motor symptoms and development of a screening tool for osteoporosis in Parkinson's disease

BACKGROUND AND PURPOSE

Parkinson's disease (PD) patients have a higher likelihood of having osteoporosis compared to controls, therefore deserving special attention. This study was to 1) investigate the association of non-motor symptoms with osteoporosis amongst PD patients, and 2) develop screening tools for osteoporosis.

MATERIALS AND METHODS

PD Patients were included (n = 109). The factors/variables were obtained from clinical records due to the retrospective nature of this study. The bone mineral density (BMD) of the lumbar spine and femoral neck was examined using a dual-energy X-ray absorptiometry machine, according to which they were categorized as either having (T-score ≤ -2.5) or not having osteoporosis (T-score>-2.5) at the two sites. The non-motor symptoms were assessed using clinical scales, including non-motor experiences of daily living, depression, anxiety, cognitive function, and autonomic function. The potential covariates included demographic and clinical factors/variables, such as age and sex. Logistic regression was used to investigate the associations and establish the screening tools.

RESULTS

Patients with autonomic dysfunction had significantly (p = 0.011) higher odds of having femoral neck osteoporosis compared to those with no/minimal dysfunction after adjusting for sex, disease duration, and body mass index, demonstrating a strong association (odds ratio=12.81). Based on the four factors/variables, a screening tool with a good accuracy was established (C-statistic = 0.85).

CONCLUSION

PD patients with autonomic dysfunction had greater odds of having femoral neck osteoporosis compared to those with no/minimal dysfunction. The screening tool may lay a foundation for developing screening models with higher accuracy to identify which PD patients may require a BMD test.

Mindful Eating and Current Glycemic Control in Patients With Type 2 Diabetes

Objective Lifestyle adjustments are essential in the management of type 2 diabetes mellitus (T2DM). Mindful eating involves being more attentive to and aware of meals. This study aimed to investigate the relationship between mindful eating and glycemic control, as well as body mass index (BMI), in people with T2DM. Materials and methods This cross-sectional study included 448 participants who had been diagnosed with T2DM for at least six months. The participants were categorized into three groups based on their HbA1c levels. The Turkish adaptation of the Mindful Eating Questionnaire (MEQ-30) was employed to assess levels of mindful eating behavior. Obesity was defined as a BMI ≥ 30. Anthropometric measurements, laboratory tests, and questionnaire responses were also collected. Results Participants with well-controlled diabetes (HbA1c ≤7%) demonstrated significantly higher scores on the MEQ-30 and its various subgroups in comparison to those with poorly controlled diabetes (HbA1c >9%). The suboptimal glycemic control groups exhibited noticeable variations in mindful eating behaviors. Moreover, participants with lower BMIs displayed stronger inclinations toward mindful eating. Weak negative correlations were observed between BMI and specific MEQ-30 subgroups. Notably, subgroups such as emotional eating, eating control, eating discipline, and interference demonstrated weak negative correlations with the HbA1c levels. Conclusion  Higher levels of mindful eating were associated with lower levels of HbA1c and BMI, indicating that incorporating mindful eating practices may present promising advantages for individuals diagnosed with type 2 diabetes, specifically in terms of glycemic control and weight management.

Global trends and developments in mindfulness interventions for diabetes: a bibliometric study

BACKGROUND

Diabetes is a metabolic disorder posing a global threat to health. Many scholars are dedicated to developing non-pharmacological therapies, and mindfulness intervention is among the potentially effective approaches. Due to the rapid increase in relevant research in recent years, along with the diverse focus and interventions used in studies, it has become challenging for practitioners to quickly comprehend the key features of this field and the directions worth paying attention to. Bibliometric analysis, in response, can help scholars understand this field and identify points of interest.

METHODS

Publications related to mindfulness intervention in diabetes from the establishment of the Web of Science Core Collection (WOSCC) to September 2023 were searched. We employed four bibliometric techniques: General Analysis of Publications, Collaborative Network Analysis, Co-citation Analysis, and Keyword Analysis. The CiteSpace 6.1.R was used to analyze the literature with the strongest citation bursts, while VOSviewer 1.6.13 was used to provide visualizations of publicly available data by analyzing co-citations or co-authorship affiliations.

RESULTS

We found a total of 387 articles. The results indicate that research on this topic has been steadily increasing over time. The United States is the top producer of relevant publications, with Tilburg University being the institution that publishes the most articles. The journal "Mindfulness" has the highest publication count. In the collaborative network analysis, the United States emerged as the main hub for global cooperation in this research field, contributing 182 articles with a total of 5872 citations. The journal "Diabetes Care" was frequently cited and played a central role. The keyword analysis revealed that researchers have shown a strong interest in how mindfulness interventions affect the mental health of diabetic individuals. Additionally, there is a focus on studying elderly diabetic groups and exploring how mindfulness interventions impact metabolic diseases. These areas are currently the main research priorities.

CONCLUSION

Our findings demonstrate the current trend and hotspots in mindfulness intervention and offer some directions for future research.

Meditation for the primary and secondary prevention of cardiovascular disease

BACKGROUND

Interventions incorporating meditation to address stress, anxiety, and depression, and improve self-management, are becoming popular for many health conditions. Stress is a risk factor for cardiovascular disease (CVD) and clusters with other modifiable behavioural risk factors, such as smoking. Meditation may therefore be a useful CVD prevention strategy.

OBJECTIVES

To determine the effectiveness of meditation, primarily mindfulness-based interventions (MBIs) and transcendental meditation (TM), for the primary and secondary prevention of CVD.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, three other databases, and two trials registers on 14 November 2021, together with reference checking, citation searching, and contact with study authors to identify additional studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of 12 weeks or more in adults at high risk of CVD and those with established CVD. We explored four comparisons: MBIs versus active comparators (alternative interventions); MBIs versus non-active comparators (no intervention, wait list, usual care); TM versus active comparators; TM versus non-active comparators.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were CVD clinical events (e.g. cardiovascular mortality), blood pressure, measures of psychological distress and well-being, and adverse events. Secondary outcomes included other CVD risk factors (e.g. blood lipid levels), quality of life, and coping abilities. We used GRADE to assess the certainty of evidence.

MAIN RESULTS

We included 81 RCTs (6971 participants), with most studies at unclear risk of bias. MBIs versus active comparators (29 RCTs, 2883 participants) Systolic (SBP) and diastolic (DBP) blood pressure were reported in six trials (388 participants) where heterogeneity was considerable (SBP: MD -6.08 mmHg, 95% CI -12.79 to 0.63, I2 = 88%; DBP: MD -5.18 mmHg, 95% CI -10.65 to 0.29, I2 = 91%; both outcomes based on low-certainty evidence). There was little or no effect of MBIs on anxiety (SMD -0.06 units, 95% CI -0.25 to 0.13; I2 = 0%; 9 trials, 438 participants; moderate-certainty evidence), or depression (SMD 0.08 units, 95% CI -0.08 to 0.24; I2 = 0%; 11 trials, 595 participants; moderate-certainty evidence). Perceived stress was reduced with MBIs (SMD -0.24 units, 95% CI -0.45 to -0.03; I2 = 0%; P = 0.03; 6 trials, 357 participants; moderate-certainty evidence). There was little to no effect on well-being (SMD -0.18 units, 95% CI -0.67 to 0.32; 1 trial, 63 participants; low-certainty evidence). There was little to no effect on smoking cessation (RR 1.45, 95% CI 0.78 to 2.68; I2 = 79%; 6 trials, 1087 participants; low-certainty evidence). None of the trials reported CVD clinical events or adverse events. MBIs versus non-active comparators (38 RCTs, 2905 participants) Clinical events were reported in one trial (110 participants), providing very low-certainty evidence (RR 0.94, 95% CI 0.37 to 2.42). SBP and DBP were reduced in nine trials (379 participants) but heterogeneity was substantial (SBP: MD -6.62 mmHg, 95% CI -13.15 to -0.1, I2 = 87%; DBP: MD -3.35 mmHg, 95% CI -5.86 to -0.85, I2 = 61%; both outcomes based on low-certainty evidence). There was low-certainty evidence of reductions in anxiety (SMD -0.78 units, 95% CI -1.09 to -0.41; I2 = 61%; 9 trials, 533 participants; low-certainty evidence), depression (SMD -0.66 units, 95% CI -0.91 to -0.41; I2 = 67%; 15 trials, 912 participants; low-certainty evidence) and perceived stress (SMD -0.59 units, 95% CI -0.89 to -0.29; I2 = 70%; 11 trials, 708 participants; low-certainty evidence) but heterogeneity was substantial. Well-being increased (SMD 0.5 units, 95% CI 0.09 to 0.91; I2 = 47%; 2 trials, 198 participants; moderate-certainty evidence). There was little to no effect on smoking cessation (RR 1.36, 95% CI 0.86 to 2.13; I2 = 0%; 2 trials, 453 participants; low-certainty evidence). One small study (18 participants) reported two adverse events in the MBI group, which were not regarded as serious by the study investigators (RR 5.0, 95% CI 0.27 to 91.52; low-certainty evidence). No subgroup effects were seen for SBP, DBP, anxiety, depression, or perceived stress by primary and secondary prevention. TM versus active comparators (8 RCTs, 830 participants) Clinical events were reported in one trial (201 participants) based on low-certainty evidence (RR 0.91, 95% CI 0.56 to 1.49). SBP was reduced (MD -2.33 mmHg, 95% CI -3.99 to -0.68; I2 = 2%; 8 trials, 774 participants; moderate-certainty evidence), with an uncertain effect on DBP (MD -1.15 mmHg, 95% CI -2.85 to 0.55; I2 = 53%; low-certainty evidence). There was little or no effect on anxiety (SMD 0.06 units, 95% CI -0.22 to 0.33; I2 = 0%; 3 trials, 200 participants; low-certainty evidence), depression (SMD -0.12 units, 95% CI -0.31 to 0.07; I2 = 0%; 5 trials, 421 participants; moderate-certainty evidence), or perceived stress (SMD 0.04 units, 95% CI -0.49 to 0.57; I2 = 70%; 3 trials, 194 participants; very low-certainty evidence). None of the trials reported adverse events or smoking rates. No subgroup effects were seen for SBP or DBP by primary and secondary prevention. TM versus non-active comparators (2 RCTs, 186 participants) Two trials (139 participants) reported blood pressure, where reductions were seen in SBP (MD -6.34 mmHg, 95% CI -9.86 to -2.81; I2 = 0%; low-certainty evidence) and DBP (MD -5.13 mmHg, 95% CI -9.07 to -1.19; I2 = 18%; very low-certainty evidence). One trial (112 participants) reported anxiety and depression and found reductions in both (anxiety SMD -0.71 units, 95% CI -1.09 to -0.32; depression SMD -0.48 units, 95% CI -0.86 to -0.11; low-certainty evidence). None of the trials reported CVD clinical events, adverse events, or smoking rates.

AUTHORS' CONCLUSIONS

Despite the large number of studies included in the review, heterogeneity was substantial for many of the outcomes, which reduced the certainty of our findings. We attempted to address this by presenting four main comparisons of MBIs or TM versus active or inactive comparators, and by subgroup analyses according to primary or secondary prevention, where there were sufficient studies. The majority of studies were small and there was unclear risk of bias for most domains. Overall, we found very little information on the effects of meditation on CVD clinical endpoints, and limited information on blood pressure and psychological outcomes, for people at risk of or with established CVD. This is a very active area of research as shown by the large number of ongoing studies, with some having been completed at the time of writing this review. The status of all ongoing studies will be formally assessed and incorporated in further updates.

Effect of mindfulness-based interventions on people with prehypertension or hypertension: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Hypertension and prehypertension have been widely recognized as the main contributors of global mortality. Evidence shows mindfulness-based interventions may reduce blood pressure and improve mental health. However, the effect of mindfulness-based interventions on blood pressure and mental health has not been fully understood.

METHODS

Potential studies published before May 24th 2023 were identified by searching Embase, Ovid Emcare, PsycINFO, CINAHL, Web of Science, Cochrane, PubMed, China National Knowledge Infrastructure, Wanfang database, and VIP China Science. Additionally, two grey databases were searched: Mednar, WorldWideScience.org. The risk of bias in the included studies was assessed using the Cochrane Risk of Bias Assessment tool. The random-effects meta-analyses were conducted using Review Man 5.4 software and the key outcomes are presented as mean difference or standard mean difference and the 95% confidential interval.

RESULTS

Searches returned 802 studies in total, of which 12 were included (N = 715). The duration of interventions was 8 weeks in 10 trials and 6 weeks in one trial. Pooled effect sizes indicated reductions in systolic blood pressure (MD = - 9.12, 95% CI [- 12.18, - 6.05], p < 0.001), diastolic blood pressure (MD = - 5.66, 95% CI [- 8.88, - 2.43], p < 0.001), anxiety (SMD = - 4.10; 95% CI [- 6.49, - 1.71], p < 0.001), depression (SMD = - 1.70, 95%CI [- 2.95, - 0.44], p < 0.001) and perceived stress (SMD = - 5.91, 95%CI [- 8.74, - 3.09], p < 0.001) at post-intervention. The findings from subgroup analyses are favorable for mindfulness-based interventions regardless of gender and baseline blood pressure with regard to BP reduction, with a more profound effect observed in participants with higher pre-intervention blood pressure.

CONCLUSIONS

The results provide evidence for the positive role of mindfulness-based interventions in hypertension management. More large randomized control trials with sufficient statistical power and long-term follow-up are needed.

TRIAL REGISTRATION

The protocol had been registered with Prospero on October 2nd 2021 (registration NO. CRD42021282504 ).

Effects of mindfulness-based interventions on cardiovascular risk factors: An umbrella review of systematic reviews and meta-analyses

OBJECTIVE

Reviews have shown that mindfulness-based interventions (MBIs) were effective in improving cardiovascular risk factors (CVRFs), but the results were contradictory. This umbrella review aimed to summarize and grade the existing reviews on CVRFs associated with MBIs.

METHODS

The protocol of this umbrella review had been registered in PROSPERO (CRD42022356812). PubMed, Web of science, Embase, The Cochrane Library, Scopus, Medline, PsycINFO and CINAHL were searched from database inception to 20 July 2022. The quality of evidence was assessed through GRADE.

RESULTS

Twenty-seven reviews with 14,923 participants were included. Overall, 45% of reviews had low heterogeneity (I2 < 25%). For the quality of evidence, 31% were rated very low, 42% were rated low, 17% were rated moderate and 10% were rated high. MBIs significantly improved systolic blood pressure [SMD -5.53 mmHg (95% CI -7.81, -3.25)], diastolic blood pressure [SMD -2.13 mmHg (95% CI -2.97, -1.30)], smoking [Cohen's d 0.42 (95% CI 0.20, 0.64)], glycosylated hemoglobin [MD 0.01 (95% CI -0.43, -0.07)], binge eating behavior [SMD -6.49 (95% CI -10.80, -2.18)], depression [SMD -0.72 (95% CI -1.23, -0.21)] and stress [SMD -0.67 (95% CI -1.00, -0.34)].

CONCLUSIONS

In conclusion, this umbrella review provided evidence for the role of MBIs in the improvement of CVRFs.

Effects of Meditation Intervention on Self-management in Adult Patients With Type 2 Diabetes: A Systematic Literature Review and Meta-analysis

BACKGROUND

Diabetes complications are prevalent and cause adverse effects on the physical, psychological, and economic status of adult patients with type 2 diabetes. Meditation may positively affect self-management and, in turn, reduce diabetes complications. However, the systematic examination of the effects of meditation without additional components on self-management in this population have been rarely examined.

PURPOSE

The aim of this study was to examine the effects of meditation interventions on self-management (ie, control of glucose, blood pressure, cholesterol, and obesity and self-management) among adult patients with type 2 diabetes in randomized controlled trials.

METHODS

In this systematic review and meta-analysis, 6 electronic databases were searched using major keywords of meditation , diabetes , and self-management during March 2022.

RESULTS

Eight studies (9 articles) using mindfulness-based meditation were included. The meta-analysis showed that meditation improved hemoglobin A 1c (effect size = -0.75; 95% confidence interval, -1.30 to -0.21; P = .007) but not fasting blood glucose. Only a few studies examined meditation effects on other types of self-management (eg, blood pressure, body mass index, cholesterol, diet, exercise, foot care, and monitoring of blood glucose), and the effects were inconsistent. In 1 study, meditation improved diabetes self-management.

CONCLUSIONS

Mindfulness-based meditation reduced hemoglobin A 1c levels in adult patients with type 2 diabetes but did not consistently improve other types of self-management in a few studies examined. This may imply the need for additional intervention components to improve different types of self-management. Further studies are needed to examine the effects of different types of meditations with additional components on different types of self-management.

The Effects of Mindfulness on Glycemic Control in People with Diabetes: An Overview of Systematic Reviews and Meta-Analyses

Background: Previous research has demonstrated the effectiveness of mindfulness interventions in improving glycemic control. By enhancing attention control, emotion regulation, and self-awareness, mindfulness shows promise in managing the lifestyle factors associated with cardiovascular disease risk. However, the impact of mindfulness on glycemic control in people with diabetes remains unclear. This overview aims to summarize the current evidence of the impact of mindfulness interventions on glycemic control in people with diabetes and propose suggestions for future research. Methods: The author searched electronic databases (PubMed/MEDLINE, Embase, and Cochrane Library) to identify relevant systematic reviews and meta-analyses. The current evidence regarding the effects of mindfulness on glycemic control in people with diabetes was summarized. Results: This review evaluated a total of five systematic reviews and meta-analyses of randomized controlled trials (RCTs). Mindfulness interventions show potential for improving glycemic control as measured by hemoglobin A1c (HbA1c) levels, as well as reducing stress, depression, and anxiety in people with diabetes. Four out of five systematic reviews and meta-analyses reported a significant reduction in HbA1c levels by approximately 0.3%. However, the available studies lacked adequate description of key characteristics of study subjects, such as body mass index, medication, and disease conditions, which are essential for assessing the impact of mindfulness on glycemic control. Moreover, there was significant heterogeneity in the intervention methods employed across the included RCTs. Conclusions: Mindfulness interventions are effective in improving glycemic control in people with type 2 diabetes. However, the overall quality of the reviewed studies raises uncertainty regarding the effectiveness of mindfulness as a treatment for people with diabetes. Further research is necessary to elucidate the biological effects of mindfulness on physiological, neurological, and endocrinological functions in humans.

Psychological Support Strategies for Adults With Type 2 Diabetes in a Very Low-Carbohydrate Web-Based Program: Randomized Controlled Trial

BACKGROUND

A very low-carbohydrate (VLC) nutritional strategy may improve glycemic control and weight loss in adults with type 2 diabetes (T2D). However, the supplementary behavioral strategies that might be able to improve outcomes using this nutritional strategy are uncertain.

OBJECTIVE

This study aims to compare the impact of adding 3 different supplementary behavioral strategies to a web-based VLC diet intervention. To our knowledge, this is the first trial to randomize participants to different frequencies of dietary self-monitoring.

METHODS

The study included 112 overweight adults with T2D (hemoglobin A1c ≥6.5%) taking no antiglycemic medications or only metformin. They received a remotely delivered 12-month VLC diet intervention. Participants were randomly assigned through a full factorial 2×2×2 design to supplementary strategies: either daily or monthly dietary self-monitoring, either mindful eating training or not, and either positive affect skills training or not. Our research goal was to determine whether 3 different supplemental strategies had at least a medium effect size (Cohen d=0.5).

RESULTS

Overall, the VLC intervention led to statistically significant improvements in glycemic control (-0.70%, 95% CI -1.04% to -0.35%; P<.001), weight loss (-6.82%, 95% CI -8.57% to -5.08%; P<.001), and depressive symptom severity (Cohen d -0.67, 95% CI -0.92 to -0.41; P<.001). Furthermore, 30% (25/83) of the participants taking metformin at baseline reduced or discontinued their metformin. Only 1 Cohen d point estimate reached 0.5; daily (vs monthly) dietary self-monitoring had a worse impact on depressive symptoms severity (Cohen d=0.47, 95% CI -0.02 to 0.95; P=.06). None of the strategies had a statistically significant effect on outcomes. For changes in our primary outcome, hemoglobin A1c, the daily (vs monthly) dietary self-monitoring impact was 0.42% (95% CI -0.28% to 1.12%); for mindful eating, it was -0.47% (95% CI -1.15% to 0.22%); and for positive affect, it was 0.12% (95% CI -0.57% to 0.82%). Other results for daily (vs monthly) dietary self-monitoring were mixed, suggesting an increase in weight (0.98%) and depressive symptoms (Cohen d=0.47), less intervention satisfaction (Cohen d=-0.20), more sessions viewed (3.02), and greater dietary adherence (Cohen d=0.24). For mindful eating, the results suggested a benefit for dietary adherence (Cohen d=0.24) and intervention satisfaction (Cohen d=0.30). For positive affect, the results suggested a benefit for depressive symptoms (Cohen d=-0.32), the number of sessions viewed (3.68), dietary adherence (Cohen d=0.16), and intervention satisfaction (Cohen d=0.25).

CONCLUSIONS

Overall, our results support the use of a VLC diet intervention in adults with T2D. The addition of monthly (not daily) dietary self-monitoring, mindful eating, and positive affect skills training did not show a definitive benefit, but it is worth further testing.

Effects of Mind-Body Training as a Mental Health Therapy in Adults with Diabetes Mellitus Type II: A Systematic Review

The increase in the prevalence and disease burden of diabetes has highlighted the need to strengthen a comprehensive care system that includes mental health treatment. A systematic review was carried out to analyze the effectiveness of mind-body training as a therapy for the mental health management of adult patients with type 2 diabetes mellitus (T2DM) following the PRISMA 2020 guidelines. Pubmed, Scopus and Web of Science databases were consulted between November and December 2022. Eight articles were selected according to the inclusion and exclusion criteria. Only randomized controlled trials were included. The interventions focused on mindfulness and yoga with variable durations of between 8 weeks and 6 months. Four of the included studies observed statistically significant changes (p < 0.05) in anxiety. Six articles determined that mind-body training was effective for treating depression. Finally, five articles found favorable effects on stress, while one did not observe changes at 8 weeks of intervention or after 1 year of follow-up. The evidence supports the use of mind-body training to reduce stress, depression, and anxiety levels in the adult population with T2DM, which makes this type of training a valuable intervention to be included in an integral approach to diabetic pathology.

Mindfulness, disordered eating, and impulsivity in relation to glycemia among adolescents with type 1 diabetes and suboptimal glycemia from the Flexible Lifestyles Empowering Change (FLEX) intervention trial

OBJECTIVE

To assess the relationship between mindfulness and glycemia among adolescents with type 1 diabetes (T1D) with suboptimal glycemia, and evaluate the potential mediation by ingestive behaviors, including disordered eating, and impulsivity.

RESEARCH DESIGN AND METHODS

We used linear mixed models for hemoglobin A1c (HbA1c) and linear regression for continuous glucose monitoring (CGM) to study the relationship of mindfulness [Child and Adolescent Mindfulness Measure (CAMM)] and glycemia in adolescents with T1D from the 18-month Flexible Lifestyles Empowering Change (FLEX) trial. We tested for mediation of the mindfulness-glycemia relationship by ingestive behaviors, including disordered eating (Diabetes Eating Problem Survey-Revised), restrained eating, and emotional eating (Dutch Eating Behavior Questionnaire); and impulsivity (total, attentional, and motor, Barrett Impulsiveness Scale).

RESULTS

At baseline, participants (n = 152) had a mean age of 14.9 ± 1.1 years and HbA1c of 9.4 ± 1.2% [79 ± 13 mmol/mol]. The majority of adolescents were non-Hispanic white (83.6%), 50.7% were female, and 73.0% used insulin pumps. From adjusted mixed models, a 5-point increase in mindfulness scores was associated with a -0.19% (95%CI -0.29, -0.08, p = 0.0006) reduction in HbA1c. We did not find statistically significant associations between mindfulness and CGM metrics. Mediation of the relationship between mindfulness and HbA1c by ingestive behaviors and impulsivity was not found to be statistically significant.

CONCLUSIONS

Among adolescents with T1D and suboptimal glycemia, increased mindfulness was associated with lower HbA1c levels. Future studies may consider mindfulness-based interventions as a component of treatment for improving glycemia among adolescents with T1D, though more data are needed to assess feasibility and efficacy.

Effects of an integrated mindfulness intervention for veterans with diabetes distress: a randomized controlled trial

INTRODUCTION

US military veterans have disproportionately high rates of diabetes and diabetes-related morbidity in addition to being at risk of comorbid stress-related conditions. This study aimed to examine the effects of a technology-supported mindfulness intervention integrated into usual diabetes care and education on psychological and biobehavioral outcomes.

RESEARCH DESIGN AND METHODS

Veterans (N=132) with type 1 or 2 diabetes participated in this two-arm randomized controlled efficacy trial. The intervention arm received a one-session mindfulness intervention integrated into a pre-existing program of diabetes self-management education and support (DSMES) plus one booster session and 24 weeks of home practice supported by a mobile application. The control arm received one 3-hour comprehensive DSMES group session. The primary outcome was change in diabetes distress (DD). The secondary outcomes were diabetes self-care behaviors, diabetes self-efficacy, post-traumatic stress disorder (PTSD), depression, mindfulness, hemoglobin A1C (HbA1C), body weight, and blood pressure. Assessments were conducted at baseline, 12 weeks, and 24 weeks. Participant satisfaction and engagement in home practice were assessed in the intervention group at 12 and 24 weeks.

RESULTS

Intention-to-treat group by time analyses showed a statistically significant improvement in DD in both arms without significant intervention effect from baseline to 24 weeks. Examination of distal effects on DD between weeks 12 and 24 showed significantly greater improvement in the intervention arm. Improvement in DD was greater when baseline HbA1C was <8.5%. A significant intervention effect was also shown for general dietary behaviors. The secondary outcomes diabetes self-efficacy, PTSD, depression, and HbA1C significantly improved in both arms without significant intervention effects. Mindfulness and body weight were unchanged in either group.

CONCLUSIONS

A technology-supported mindfulness intervention integrated with DSMES showed stronger distal effects on DD compared with DSMES control. Examination of longer-term outcomes, underlying mechanisms, and the feasibility of virtual delivery is warranted.

Trait Mindfulness and Mindfulness Practices in Adolescents with Type 1 Diabetes: Descriptive and Comparative Study

INTRODUCTION

Study describes mindfulness (trait and practices) and compares levels of trait mindfulness (low/high) and practices (yes/no) on demographic, clinical characteristics, and diabetes-related outcomes among adolescents with type 1 diabetes (T1D).

METHODS

Adolescents completed a survey on demographics, clinical data, trait mindfulness/practices, diabetes-specific stress, and diabetes self-management (DSM). Glycemic control (A1c) obtained from medical records. T and χ² tests were applied for comparative analyses.

RESULTS

129 adolescents (12-18 years) reported moderately high levels of mindfulness (31 ± 8; range, 10-40). One-third (30%) reported having experience with mindfulness practices (formal, informal, and religious). Adolescents who reported higher levels of trait mindfulness had higher insulin pump usage (p =.005), less diabetes-specific stress (p <.001), greater DSM (p =.006), and less A1c (p =.013). Adolescents who reported more types of mindfulness practices had greater DSM scores.

DISCUSSION

Adolescents with higher levels of trait mindfulness and with more types of mindfulness practices had better diabetes-related outcomes. Introducing mindfulness training tailored to adolescents with T1D should be examined.

Psychotherapeutic Interventions to Improve Psychological Adjustment in Type 1 Diabetes: A Systematic Review

Background: International clinical practice guidelines highlight the importance of improving the psychological and mental health care of patients with Type 1 diabetes mellitus (T1DM). Psychological interventions can promote adherence to the demands of diabetes self-care, promoting high quality of life and wellbeing. Methods: A systematic review was carried out to determine whether psychological treatments with a specific focus on emotional management have an impact on glycemic control and variables related to psychological adjustment. Comprehensive literature searches of PubMed Medline, Psycinfo, Cochrane Database, Web of Science, and Open Grey Repository databases were conducted, from inception to November 2019 and were last updated in December 2020. Finally, eight articles met inclusion criteria. Results: Results showed that the management of emotions was effective in improving the psychological adjustment of patients with T1DM when carried out by psychologists. However, the evidence regarding the improvement of glycemic control was not entirely clear. When comparing adolescent and adult populations, findings yielded slightly better results in adolescents. Conclusions: More rigorous studies are needed to establish what emotional interventions might increase glycemic control in this population.

Factors Associated with Diabetes-Related Distress in Patients with Type 2 Diabetes Mellitus

Introduction: The aim of this study was to identify factors associated with diabetes-related distress (DRD) in adult patients with type 2 diabetes mellitus (T2DM).

Material and Methods: This was an analysis of data previously obtained from two cross-sectional studies, in which medical charts review and direct interviews were employed to obtain medical and demographic data. Vital status assessment and anthropometric measurements were performed. The patients filled out specific questionnaires for DRD (DDS-17), symptoms of depression (PHQ-9), and of anxiety (GAD-7). A clinical meaningful threshold for DRD was set at ≥2.0 points. Symptoms of depression and anxiety, number of chronic complications, therapy for T2DM, anthropometric and cardio-metabolic parameters, as well as demographic, socio-economic data, and lifestyle habits were evaluated as factors possibly associated with DRD by univariate and multiple regression analyses.

Results: A total of 271 patients with T2DM were included in this analysis, of whom 25.1% presented a DDS-17 score ≥2 points (and 9.96% a DDS-17 score ≥3). Subjects with a DDS-17 score ≥2 had higher HbA1c levels (p = 0.018), PHQ-9 and GAD-7 scores (p <0.0001 for both). The multiple regression model indicated that anxiety (p = 0.026), depression (p = 0.001), and ethnicity (p = 0.002) were significantly correlated with DRD (p <0.0001). With regards to subscales, the HbA1c (p = 0.005) and PHQ-9 score (p <0.0001) were significantly associated with emotional burden, ethnicity (p = 0.001) and depression (p = 0.004) with regimen-related distress, whereas ethnicity (p = 0.010) and GAD-7 score (p = 0.012) with interpersonal distress.

Conclusions: Psychosocial factors like depression, anxiety, or ethnicity significantly contribute to DRD in patients with T2DM, and worse glycemic control is associated with emotional burden.

Contemplative sciences: A future beyond mindfulness

Mindfulness is a psychological technique based on Eastern meditative practices that was developed in the late 1970s by Kabat-Zinn at the University of Massachusetts. Initially, there was a debate over whether it should be considered a scientific technique or labelled as part of the "new wave" practices. Today, mindfulness is omnipresent in modern societies but has suffered from merchandising and banalization, which has been strongly criticized. Despite some limitations regarding methodological aspects of mindfulness research, it is considered effective for treating many physical and psychological disorders, and even it is recommended in clinical guidelines such the British National Institute for Health and Care Excellence. During the last 2500 years, mindfulness practices have moved from Northern India across most of Asia, but their mixing with Western science and culture at the end of the 20th century is considered a key event in recent history. For the first time in human history, due to globalization, the wisdom of all contemplative traditions can be shared with all human beings and assessed by science. Mindfulness practices, yoga included, are giving birth to a new field of knowledge, contemplative sciences, which go beyond mindfulness and is devoted to helping humanity to reach higher levels of happiness and mental peace.
