Efficacy of Cognitive Behavioral Therapy in Adherence to the Mediterranean Diet in Metabolic Syndrome Patients: A Randomized Controlled Trial

Comprehensive lifestyle modification interventions for metabolic syndrome: A systematic review and meta-analysis

INTRODUCTION

Previous systematic reviews and meta-analyses have mainly focused on improvements in the number of metabolic syndrome risk factors and individual changes in each risk factor, making it challenging to examine the impact of comprehensive lifestyle modification interventions on adherence to recommended health behaviors. To address this gap, we conducted a systematic and meta-analysis aimed at identifying clinical parameter levels associated with lifestyle modification outcomes and adherence to recommended health behaviors for individuals with metabolic syndrome.

METHODS

A total of seven studies retrieved from four databases (CINAHL, Medline via PubMed, American Psychological Association PsycINFO, and Embase) were included in the review. The selected studies, which demonstrated improvements in health behaviors, all included diet and exercise as main factors of comprehensive lifestyle modification in home settings.

RESULTS

Our findings suggest that a 6-month comprehensive intervention including diet and exercise can be effective in decreasing glucose levels and systolic blood pressure. However, given the limited available data, further studies investigating the efficacy of interventions of varying durations are needed.

DISCUSSION

Although our review included a small number of studies, comprehensive lifestyle modifications consisting of at least two components (primarily diet and exercise) can improve health behaviors and some clinical parameters among individuals with metabolic syndrome. Future studies are needed to investigate the long-term effects of lifestyle modifications on health behavior adherence and explore effective interventions to address certain clinical parameters, such as high-density lipoprotein levels. Also, we recommend using objective and quantifiable measure to compare adherence to recommended lifestyle modifications across studies.

CLINICAL RELEVANCE

This research provides empirical evidence of the effectiveness of comprehensive lifestyle modification and emphasizes the need to develop long-term nursing strategies in public health that can be used to effectively manage metabolic syndrome.

Efficacy of cognitive-behavioural therapy for lifestyle modification in metabolic syndrome: a randomised controlled trial with a 18-months follow-up

OBJECTIVE

To test the efficacy of cognitive-behavioural therapy (CBT) for lifestyle modification in patients with metabolic syndrome (MetS).

DESIGN

76 MetS patients completed this clinical trial, with 18 months follow-up. 45 participants from the experimental group (EG - CBT) and 31 to the control group (CG - usual care). The CBT programme was performed by a psychologist in a face-to-face group format, during 12 weekly sessions lasting 90 minutes. The intervention for the CG consisted of workshops with basic information about MetS and it's associated cardiovascular risk.

MAIN OUTCOME MEASURES

Efficacy of (CBT) in (MetS) patients.

RESULTS

Results showed reduction in weight (mean difference - MD -2.633, 95%CI [-4.322, -0.943]; p<.003), waist circumference (MD -2.944, 95%CI [-5.090, -0.798]; p<.008), body mass index (MD -0.915, 95%CI [-1.494, -0.335]; p<.003), systolic (MD -0.046, 95%CI [-0.685, -0.023]; p<.0002) diastolic blood pressure (MD -4.777, 95%CI [-7.750, -1.804]; p<.002), and cardiovascular risk score after 18 months. An increase in adherence to the Mediterranean diet and assertiveness and a reduction in anger were observed in EG. The CG did not show any significant differences.

CONCLUSION

The CBT focused on changes in lifestyle seems to be effective in the reduction of MetS and cardiovascular risk factors.

The evaluation of cognitive-behavioral therapy-based intervention on type 2 diabetes patients with comorbid metabolic syndrome: a randomized controlled trial

BACKGROUND

Cognitive behavior therapy (CBT) has been applied in intervention research in diabetes patients with satisfying results. However, there was no research on type 2 diabetes (T2DM) patients with comorbidities. This study aimed to investigate the effectiveness of CBT on psychological variables, behavior variables, quality of life, sleep quality, and physical variables among adult T2DM patients with comorbid metabolic syndrome (MS).

METHODS

281 patients aged 18-75 years were recruited from Ningbo First Hospital in China from October 2021 to March 2022. Patients were randomized to the intervention group (IG, N = 148) or control group (CG, N = 133). Patients in the IG received 12 CBT-based sessions during a six-month intervention time. Patients in the CG received the usual care only. Univariate General Linear Model was used to analyze the effect of CBT-based interventions. The analysis was conducted by SPSS Version 28.

RESULTS

Results indicated that CBT-based intervention was superior in the following aspects: relieving depression symptoms: IG (4.11 ± 4.35 vs. 1.99 ± 2.12), CG (3.40 ± 3.26 vs. 2.32 ± 1.88), interaction effect (F = 4.074, P = 0.044); enhancing diabetes self-care behaviors: IG (26.79 ± 12.18 vs. 37.49 ± 10.83), CG (25.82 ± 13.71 vs. 31.96 ± 11.72), interaction effect (F = 5.242, P = 0.022); promoting the efficacy of CBT: IG (47.45 ± 6.83 vs. 50.76 ± 4.98), CG (46.74 ± 6.94 vs. 47.87 ± 5.11), interaction effect (F = 5.198, P = 0.023); improving subjective sleep quality: IG (0.93 ± 0.68 vs. 0.69 ± 0.63), CG (1.03 ± 0.72 vs. 1.01 ± 0.68), interaction effect (F = 3.927, P = 0.048).

CONCLUSIONS

The CBT-based intervention was beneficial in improving depression symptoms, diabetes self-care behaviors, the efficacy of CBT, and sleep quality in T2DM patients with comorbid MS. The downtrend of body mass index, systolic blood pressure, diastolic pressure, and glycated hemoglobin was larger in the intervention group but not to a significant level.

Online cognitive behavioural therapy as a psychological vaccine against stress during the COVID-19 pandemic in pregnant women: A randomised controlled trial

The COVID-19 pandemic has affected the population's levels of stress and anxiety due to its contagious nature and the uncertainties generated by its novelty. One population that is especially vulnerable to these psychological consequences are pregnant women. This is why the objective of this study was to test the efficacy of an online stress management programme of a cognitive behavioural nature on pregnant women during the COVID-19 pandemic, in Spain. The trial was controlled and randomised, with a total of 207 pregnant women divided into three groups: the Online Cognitive Behavioural Therapy group (o-CBT) (N = 70); the Online Psychological Support group (o-PS) (N = 69); and the Usual Care group (UC) (N = 68). To test the therapy's efficacy, the women's resilience, perceived stress, pregnancy-specific stress and psychopathological symptoms were assessed before and after the intervention. The o-CBT and o-PS consisted of a programme of 8 group sessions (one per week). The results showed that pregnant women who participated in the o-CBT group presented lower rates of pregnancy-specific stress and perceived stress, as well as greater resilience and lower anxiety, depression and obsessions-compulsions symptoms. These data show the efficacy of the treatment programme and thus confirm the importance of implementing these types of interventions during a woman's pregnancy, especially over periods of major stress, such as during a pandemic.

An evolutionary mismatch narrative to improve lifestyle medicine: a patient education hypothesis

An evolutionary perspective provides a unifying explanation for the modifiable risk factors and lifestyle-based interventions for the leading causes of morbidity and mortality globally. Non-communicable diseases develop from an evolutionary mismatch between the prior environment and modern patterns of behavior; however, it is unclear whether an evolutionary mismatch narrative could promote positive behavior change in patients. We hypothesize that educating patients about evolutionary mismatch could augment efforts to improve healthful behavior. Specifically, explaining the 'why' behind what is being recommended could promote health literacy and adherence. Furthermore, we offer suggestions of how clinicians could educate patients about evolutionary mismatch for key-lifestyle factors, diet and physical activity, as well as several specific modern diseases. We also consider how to sidestep patients' skepticism of evolutionary theory. Here, we lay the groundwork for research on how educating patients with an evolutionary mismatch narrative could impact health behaviors and improve outcomes.

Weight Loss and Improvement of Metabolic Alterations in Overweight and Obese Children Through the I2AO2 Family Program: A Randomized Controlled Clinical Trial

Childhood obesity is a major public health concern. We wanted to evaluate the effectiveness of a multidisciplinary program based on healthy eating, exercise, cognitive-behavioral therapy, and health education to achieve weight loss and improve metabolic parameters in overweight and obese children. A randomized, controlled clinical trial with long-term follow-up (24 months) was conducted at a community care center in overweight and obese individuals aged 6-12 years. A sample of 108 children was divided into an experimental and a control group receiving a standard care program. The experimental groups received a 12-month interdisciplinary program; the results were evaluated at 4 months, the end of the intervention, and at follow-up 12 months later. Anthropometric and biological marker measurements related to metabolic alterations, dyslipidemia (based on total cholesterol), hyperglycemia, fasting glycaemia, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol in blood were recorded. The intervention had a significant effect (p < 0.001) in terms of decreased body mass index, skinfolds, and waist and arm circumferences. These changes were accompanied by biochemical changes underlying an improvement in metabolic parameters, such as a significant reduction in total cholesterol, low-density lipoprotein-cholesterol, triglycerides, and hyperglycemia and a significant increase in high-density lipoprotein-cholesterol. These effects were still significant for markers of excess weight or obesity in the experimental group 12 months after the end of the intervention, suggesting that an enduring change in healthy lifestyles had been maintained period. This interdisciplinary, nurse-led program helped to reduce childhood and adolescent excess weight and obesity and had long-lasting effects.

Cognitive Impairments and Associated Structural Brain Changes in Metabolic Syndrome and Implications of Neurocognitive Intervention

Currently, metabolic syndrome has become a global health problem. Alterations in neurocognitive functions among patients with metabolic syndrome are important issues in this disorder. In this paper, studies on metabolic syndrome were reviewed and their importance emphasized for the benefit of experts and policy makers. Metabolic syndrome activates inflammatory mediators that disrupt brain metabolism. These mediators can be activated by metabolic inflammation and microvascular disorders and may further cause damage to the white matter and impair cognitive function. These alterations can result in serious changes in cognitive abilities. The association between cognitive changes and metabolic syndrome has been independently evaluated in several studies. In addition, some areas of research in the field of metabolic syndrome include the effectiveness of neurocognitive interventions to enhance normal behaviors or reduce risky behaviors in patients. Structural brain correlates of health-related behaviors provide a basis for designing more effective behavioral interventions by identifying the corresponding brain regions and using behavioral interventions.

Effects of cognitive-behavioural therapy for stress management on stress and hair cortisol levels in pregnant women: A randomised controlled trial

OBJECTIVE

To demonstrate the effectiveness of a cognitive behavioural therapy for stress management in pregnant women in the reduction of psychological stress and hair cortisol levels.

METHODS

The trial was controlled and randomised, with a total of 78 pregnant women: control group (n-39) and Cognitive Behavioural Therapy group (n-39). To test the therapy's efficacy, an evaluation of the primary outcome (hair cortisol levels) and secondary outcomes (psychological stress, psychopathological symptomatology and resilience) was conducted before and after the treatment. The therapy was conducted during 8 sessions (one per week) in a group setting. The study was registered as a Randomised Controlled Trial with the code NCT03404141.

RESULTS

The results showed a group time interaction between hair cortisol levels, psychological stress (perceived and pregnancy-specific), and in the exacerbation and severity of psychopathological symptoms. These variables presented reductions after treatment only in the Cognitive Behavioural Therapy group.

CONCLUSIONS

Using a novel way of assessing chronic stress (psychological and objective measures as hair cortisol levels), this is the first study that has shown a decrease in both the levels of cortisol in hair and in psychological stress. This decline could have implications for maternal and fetal health.
