Effectiveness of community-based exercise intervention programme in obese adults with metabolic syndrome

The effect of physical activity intervention on blood pressure in 18 low and middle-income countries: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

In especially, low and middle-income nations (LMICs), where healthcare access may be restricted, high blood pressure (BP) is a major risk factor for cardiovascular disease and stroke, both of which can even lead to death. Altering one's lifestyle, in conjunction with medical therapy, has been demonstrated to be effective in lowering BP. Recent research has shown that physical activity (PA), in a variety of guises and to varying degrees, can be an effective means of lowering BP.

OBJECTIVE

The purpose of this meta-analysis and systematic review was to evaluate the impact that PA plays in the development of hypertension in LMICs nations.

METHODS

An exhaustive search of the available research was carried out in order to locate studies that were pertinent. We searched a number of online databases, such as SCOPUS, Medline, and Web of Science, looking for clinical trials that were published before March of 2023. Studies were only considered for inclusion if they were randomized controlled trials (RCTs), reported on the association between PA and BP, and were carried out in LMICs countries.

RESULTS

This meta-analysis incorporated a comprehensive collection of 60 studies, encompassing a total of 11,002 people, consisting of 5,630 cases and 5372 controls. The findings indicate that engaging in PA had a notable impact on decreasing systolic blood pressure (SBP), as seen by a weighted mean difference (WMD) of -7.70 mmHg, with a 95% confidence interval (CI) ranging from -9.50 to -5.91 (p < 0.001). Additionally, PA was found to have a significant influence on reducing diastolic blood pressure (DBP), as indicated by a WMD of -3.60 mmHg, with a 95% CI ranging from -4.48to -2.73(p < 0.001). The findings from subgroup analysis indicate that the observed results remained statistically significant when considering individuals with baseline SBP of 120 mmHg or lower and DBP of 80 mmHg or lower.

CONCLUSION

The incorporation of PA can significantly contribute to the mitigation of high BP within LMICs nations. Additional investigation is required to ascertain the most effective form and amount of PA in order to mitigate BP levels within these specific individuals.

Exercise as a community treatment for obesity and the metabolic disease epidemic

The obesity epidemic has continued to rise at an alarming rate and has increased health complications in children, adolescents, and adults. Resistance training, aerobic training, and a combination of the two have been shown to be effective at reducing excess adiposity and improving outcomes of obesity. The continued development of programs, community centers, or medical exercise facilities prescribing these treatments is nearing an absolute necessity to slow the advancing nature of obesity and related metabolic diseases. In this brief review, we summarize the effectiveness of these three training paradigms from a population-centric perspective.

Efficacy of a multidimensional self-management intervention on low-education women with metabolic syndrome: a cluster randomized controlled trial

Low-education women, a substantially older population, are subject to increased risks of metabolic syndrome and consequent cardiometabolic diseases; early detection and effective management were urgently needed. Ninety-nine women with metabolic syndrome, age 61 and education ≤ 6 years, from four community units were randomly assigned to either a self-management intervention (n = 51) or a control arm (n = 48). The intervention consisted of five dimensions, physical activity and diet modifications (daily exercise classes and two nutrition courses), goal setting, coaching and peer support, problem-solving, and self-monitoring. The control arm received an education leaflet. Assessments were performed at baseline, six months, and 18 months. Compared with the control, the intervention participants improved the overall rate of meeting the recommended servings for six health foods, including vegetables, dairy products, and nuts (except whole grains, fruits, and protein); the rate of meeting regular leisure-time physical activity; and criteria biomarkers-waist circumference, fasting blood glucose, high-density lipoprotein cholesterol (except blood pressure and triglycerides); as well as body weight and body mass index; consequently decreased the number of risk factors and rate of metabolic syndrome. In conclusion, the multidimensional self-management intervention improved physical activity, healthy eating, and metabolic syndrome risks among low-education women with metabolic syndrome.

Community-based lifestyle intervention improves metabolic syndrome and related markers among Kenyan adults

Purpose

Metabolic syndrome (MetS) is a major risk factor for cardiovascular diseases and type-2 diabetes. The study aimed to establish the efficacy of a community-based lifestyle intervention on MetS in Kenyan adults using randomized control trial involving a 15-months follow up.

Methods

A randomized controlled trial involving 352 (18-64 years old) adults with MetS spanning 15-months duration. Participants were recruited from a Nairobi based Mission-led outpatient clinic, randomly assigned equally into intervention and control groups. The intervention group was exposed to a community-based health education on lifestyle modification, while control group was subjected to hospital-led routine care involving treatment and general lifestyle advice. The study was structured into baseline, intervention and evaluation phases with inbuilt data collection in each phase. Physiologic, anthropometric, and clinical parameters as well lifestyle characteristics were measured at baseline, midline and end-line. The parameters were compared across the groups and between the time points during analyses using chi-square test, binary logistic, independent t-test and paired t-test.

Results

Proportion of participants with MetS declined significantly (p < 0.001) with marked (p < 0.05) improvement in markers of MetS (elevated BP, raised sugars, cholesterols, central obesity) in intervention compared to control group. The rates of consumption of fruits, vegetables, legumes, nuts and uptake of physical activity significantly (p < 0.05) improved in the intervention group. However, the intake of processed/fast foods, salt, sugar, and alcohol significantly (p < 0.05) declined in the intervention compared to controls by the end-line.

Conclusion

One in three adults under the community-based lifestyle intervention had improvement in physiologic, anthropometrics and clinical markers relevant to definition of MetS. Additionally, an improved adherence to the recommended dietary intake and increased uptake of physical activity in adults with MetS was observed. These findings underscore the feasibility, effectiveness and proof of concept for community-based lifestyle approach as a viable strategic intervention for addressing premorbid risk factors for cardiovascular CVDs and diabetes before evolving into full blown conditions in low-income settings.

Group-Based Lifestyle Intervention Strategies for Metabolic Syndrome: A Scoping Review and Strategic Framework for Future Research

Background and Objectives: Group-based lifestyle interventions reap social support benefits and have been implemented among individuals with various chronic diseases. However, there is a lack of consolidated evidence on its approaches to prevent or manage metabolic syndrome (MetS). This scoping review aims to assess the group-based lifestyle interventional strategies for MetS and provide a strategic framework for future research in this area. Materials and Methods: Scholarly databases (OVID Medline, SCOPUS, PUBMED, PsycINFO, EMBASE, and Cochrane Central Register of Controlled Trials) and reference lists of included publications were systematically searched using appropriate keywords and MeSH terms. Peer-reviewed articles published from the start of indexing to 31 December 2020 focused on individuals with or at risk for MetS were included. Results: Thirteen interventions were identified, with seven conducted among adults with MetS and six in the population at risk for MetS. Three study designs were reported-randomised controlled trials (RCTs), pre-post interventions, and quasi-experiments. Most of the interventions were based in the community or community organisations, multifaceted, led by a multidisciplinary healthcare team, and assisted by peer educators. Waist circumference showed the most promising MetS-related improvement, followed by blood pressure. Conclusions: There is growing evidence supporting group-based lifestyle interventions to improve MetS-related risk factors. In summary, four strategies are recommended for future research to facilitate group-based interventions in preventing and managing MetS.

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.

Understanding and Measuring Adaptation Level Among Community-Dwelling Patients with Metabolic Syndrome: A Cross-Sectional Survey

PURPOSE

This study aimed to translate the Roy adaptation model concept of adaptation level into measurable concepts when considering the health-related quality of life, social support, and self-efficacy of community-dwelling Chinese adults with metabolic syndrome.

PATIENTS AND METHODS

This was a descriptive cross-sectional study. Data were collected from 144 adults with metabolic syndrome in the suburban area of Hangzhou, China. Correlation analysis was performed to examine the relationships between environmental stimuli (sociodemographic characteristics), adaptation level (health-related quality of life and social support), and prerequisite of behavior (self-efficacy). Regression analysis was applied to test the effect of stimuli on adaptation level and their associations with behavior.

RESULTS

Adaptation level was potentially influenced by environmental stimuli and evaluated by the quality of life. Age and education level were related to physiological and psychological function. Besides, family income was related to physiological function. Thus, adaptation level may predict individuals' behavior towards illness management, with a percentage classification accuracy of 76.40%. The vitality and social functioning of the quality of life were identified as significant correlates of self-efficacy.

CONCLUSION

Our findings demonstrate that individuals' internal and external resources should be considered when developing nursing interventions to improve patients' adaptation level. Future research should explore whether facilitating self-efficacy among community-dwelling adults with metabolic syndrome may positively influence an individual's adaptation process in health management.

Ethnicity and Metabolic Syndrome: Implications for Assessment, Management and Prevention

The metabolic syndrome (MetS) is a constellation of cardiometabolic risk factors that identifies people at increased risk for type 2 diabetes and cardiovascular disease. While the global prevalence is 20%–25% of the adult population, the prevalence varies across different racial/ethnic populations. In this narrative review, evidence is reviewed regarding the assessment, management and prevention of MetS among people of different racial/ethnic groups. The most popular definition of MetS considers race/ethnicity for assessing waist circumference given differences in visceral adipose tissue and cardiometabolic risk. However, defining race/ethnicity may pose challenges in the clinical setting. Despite 80% of the world’s population being of non-European descent, the majority of research on management and prevention has focused on European-derived populations. In these studies, lifestyle management has proven an effective therapy for reversal of MetS, and randomised studies are underway in specific racial/ethnic groups. Given the large number of people at risk for MetS, prevention efforts need to focus at community and population levels. Community-based interventions have begun to show promise, and efforts to improve lifestyle behaviours through alterations in the built environment may be another avenue. However, careful consideration needs to be given to take into account the unique cultural context of the target race/ethnic group.

Recreational Centres' Facilities and Activities to Support Healthy Ageing in Singapore

Objective: This study examined the physical and social environment (facilities and activities) of Singapore’s Recreational Centres (RCs) and female patrons’ (>50 years) perception of the RC facilities and activities. Materials and Methods: A total of 100 RCs were audited, and 22 face-to-face interviews were undertaken. Results: Physical activity classes were the main activity offered (mean = eight classes per month), with walking (29.8%) and aerobics sessions (17.5%) being the most frequent. Nutrition classes and social activities were offered less often (mean = one class per month). The activities were well received by patrons, offering opportunities to interact while participating in physical activity and nutrition classes. However, the need for staff training, consideration of patron’s abilities and the desire to engage in alternative activities were expressed. Conclusion: Overall, RCs’ facilities and activities were well liked by the patrons but opportunities for improvements were identified. Regular reviews of facilities and activities through consultation with the RC patrons and managers are needed to ensure that the facilities and activities remain relevant and practical to the patrons. This will help to support active lifestyles and healthy eating practices among older adults residing within the community.

Nonpharmacologic management of hypertension: a multidisciplinary approach

PURPOSE OF REVIEW

Nonpharmacologic lifestyle modification interventions (LMIs), such as increasing physical activity, dietary modification, weight-loss, reducing alcohol consumption and smoking cessation, are effective strategies to lower resting blood pressures (BPs) in prehypertensive or hypertensive patients. However, the limited time shared between a physician and a patient is not adequate to instill an adoption of LMI. The purpose of this review is to therefore highlight evidence-based BP lowering, LMI strategies that can feasibly be implemented in clinical practices.

RECENT FINDINGS

Interventions focusing on modifying physical activity, diet, weight-loss, drinking and smoking habits have established greater efficacy in reducing elevated BP compared with providing guideline recommendations based on national guidelines. Alone greater reductions in BP can be achieved through programmes that provide frequent contact time with exercise, nutrition and/or wellness professionals. Programmes that educate individuals to lead peer support groups can be an efficient method of ensuring compliance to LMI.

SUMMARY

Evidence of a multidisciplinary approach to LMI is an effective and attractive model in managing elevated BP. This strategy is an attractive model that provides the necessary patient attention to confer lifestyle maintenance.

Effectiveness of the I2AO2 interdisciplinary programme led by nurses on metabolic syndrome and cardiovascular risk: a randomized, controlled trial

Objective To evaluate the effectiveness of an interdisciplinary programme led by nurses in relation to metabolic syndrome (MS) and cardiovascular risk (CVR). Methods This randomized, controlled, clinical trial included 74 patients diagnosed with MS (experimental group [EG], n = 37; control group [CG], n = 37). The intervention consisted of a 12-month interdisciplinary programme (pre-test, 6 months of intervention, 12 months of intervention, and 1-year follow-up post-intervention) coordinated by nursing. Results We found a progressive and significant reduction for all clinical, biochemical, and anthropometric parameters analysed at different time points. In the EG, remission of MS by 48.1% in the short term was observed (83.8% in the medium term) and maintained at 1 year post-intervention. In the CG, the prevalence of MS increased by 2.7% from the initial evaluation to study completion. A similar trend was observed for CVR. In the EG, 100% of subjects had a moderate-low risk of CVR at 1 year post-intervention, whereas the CG had CVR in all categories. Conclusion An interdisciplinary, nurse-led programme improves participants' metabolic and cardiovascular health, while maintaining long-term effects. Our findings suggest an important role of the professional nurse as a nexus between the patient, different professionals, and the community.

Impact of the I2AO2 interdisciplinary program led by nursing on psychological comorbidity and quality of life: Randomized controlled clinical trial

OBJECTIVE

Obesity is an entity of highly prevalent multifactorial origin with associated metabolic and psychological comorbidity, causing a negative impact on the quality of life of those who suffer from it. The objective is to evaluate the impact of an interdisciplinary program for nurse-led obesity on quality of life related to health and anxiety.

METHODS

Randomized controlled clinical trial with a sample of 74 subjects diagnosed with obesity (EG: n=37; CG: n=37). The intervention consisted of a 12-month interdisciplinary program (with pre-test, 12month and 24month follow-up) coordinated by nurses.

RESULTS

The anxiety analysis shows that there is no effect of the intervention on S-STAI (F2; 144=0.246; p=0.782), which has increased in both groups. However, there is an effect on T-STAI (F2; 144=8872; p<0.001), which only increases in the control group. The interdisciplinary program has significantly improved health-related quality of life (SF-36), both in physical health parameters as well as in mental health.

CONCLUSION

The interdisciplinary program led by nursing professionals has improved the quality of life related to health and has prevented the increase of anxiety-trait in participants, maintaining the long-term effects.

Long-Term Lifestyle Intervention in Elderly With Metabolic Syndrome

The purpose of this study was to examine the effects of a long-term community-based lifestyle intervention on the biochemical indicators and prevalence of metabolic syndrome among elderly adults. This was a randomized controlled trial in northern Taiwan from August 2013 to February 2015. Sixty-nine elderly adults participated in this study. There were three measurements. The experimental group participated in exercise and diet interventions. The control group participated in the exercise intervention. Repeated measurement and ANCOVA were performed to evaluate the effectiveness. After 18 months, body weight (1.06 kg), body mass index (1.21 kg/m2), waist circumference (3.32 cm), blood pressure, and prevalence (30.4%) of metabolic syndrome were significantly reduced in all subjects. There were significant differences in waist circumference and high-density lipoprotein cholesterol between the two groups. This intervention can lower the indicators and prevalence of metabolic syndrome. Exercise and diet interventions could promote further metabolic changes.

Sitting-Time and Exercise Predict Depressive Symptoms Among Taiwanese Middle-Aged Adults

BACKGROUND

Exercise and sitting-time may influence depressive symptoms.

OBJECTIVE

The purpose of this study was to examine the relationship between sitting-time, exercise, and depressive symptoms among middle-aged adults.

DESIGN

Data from community-based physical examinations between 2013 and 2014 in northern Taiwan were used for this cross-sectional study. We collected demographic data and data on exercise behaviours, sitting-time, and depressive symptoms.

RESULTS

A total of 655 participants completed this survey. Of these, 21.2% had depressive symptoms, 33.7% had regular exercise habits, and 24.1% reported a daily average sitting-time of more than 6 hours. Subjects who had regular exercise with lower sitting-time (odds ratio [OR] = 0.49), subjects who had regular exercise with higher sitting-time (OR = 0.55), and subjects who did not have regular exercise with lower sitting-time (OR = 0.34) had less prevalence of depressive symptoms compared to subjects without regular exercise and with higher sitting-time.

CONCLUSIONS

Middle-aged adults must exercise regularly and reduce sitting-time to prevent depressive symptoms.
