Randomized controlled trial on the long-term efficacy of a multifaceted, interdisciplinary lifestyle intervention in reducing cardiovascular risk and improving lifestyle in patients at risk of cardiovascular disease

Effect of educational intervention based on the theory of planned behavior (TPB) on amount of salt intake in pregnant women with PreHypertension

BACKGROUND

Prehypertension is one of the common disorders during pregnancy. Reducing salt intake is among the best cost-effective interventions to reduce the risk of hypertension. The present study aimed to explore the effect of an educational intervention based on the Theory of Planned Behavior (TPB) on amount of salt consumed by prehypertensive pregnant women.

METHODS

The present quasi-experimental study was conducted in 2022 on 61 prehypertensive pregnant women visiting the Comprehensive Health Services Centers in Birjand, Iran. Pregnant women were selected through a convenience sampling method and randomly assigned to intervention and control groups. A blood pressure test and a 24-hour urine test were taken in 3 stages (before, immediately after, and one month after the intervention). A reliable and valid questionnaire based on the TPB was used to measure the cognitive variables. The intervention program included three training sessions based on the TPB held on an online platform (WhatsApp social network). Data were analyzed using repeated measures ANOVA and longitudinal marginal model with the GEE approach in SPSS19. The significance level for all statistical tests was set at p < 0 0.05.

RESULTS

After intervention, the mean score of perceived behavioral control (p = 0.02), intention (p = 0.004), and salt consumption behavior (p = 0.03) increased significantly in the intervention group, and the mean score of systolic blood pressure (p < 0.001) and diastolic blood pressure (P < 0.01) decreased significantly in this group. In the control group, a statistically significant difference was observed in the systolic and diastolic blood pressure of the subjects (p < 0.01). However, the score of attitude, subjective norms, perceived behavioral control, intention, salt consumption behavior and the daily salt intake did not show a statistically significant difference over time (P < 0.05).

CONCLUSION

The present findings showed that the perceived behavioral control, intention, behavior, systolic and diastolic blood pressure can be modifiable variables to improve the amount of salt consumed by pre-hypertensive pregnant women. Therefore, we recommend that the present model be used to develop interventions to improve health indicators in pregnant women as a highly susceptible group in society.

Effectiveness of Integrated Care for Diabetes Mellitus Type 2, Cardiovascular and Chronic Respiratory Diseases: A Systematic Review and Meta-Analysis

Introduction

In this paper, we use the Rainbow Model of Integrated Care (RMIC) framework to evaluate the effectiveness of integrated care in terms of enhancing the outcomes of chronic conditions such as diabetes mellitus type 2 (DMT2), cardiovascular diseases (CVD), chronic respiratory diseases (CRD), or their combinations.

Methods

The data extracted from randomized controlled trials (RCT) of integrated care interventions for DMT2, CVD, and CRD (follow-up ≥ 3 months) in 11 databases were analysed using random-effects meta-analysis.

Results

A total of 54 eligible studies covering 12,976 participants, with a mean follow-up of 54 weeks, were included. In moderate-quality evidence, integrated care interventions reduced mortality for CVD, adverse events for CVD and DMT2, and improved quality of life for CVD and DMT2, physical and mental functioning, self-management, and blood pressure control.

Conclusion

Integrated care can reduce all-cause mortality, adverse events, and improve quality of life, physical and mental functioning, self-management and blood pressure control in chronic disease patients. However, available evidence for some outcomes (e.g., all-cause hospital admissions) remains uncertain.

Cardiovascular Disease Risk Screening for Commercial Drivers Examined in Occupational Practice: Implementing Evidence-Based Practice to Champion the Health of Essential Workers

BACKGROUND

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality in the United States, with 20% of deaths in adults under age 65. Commercial drivers have an increased CVD incidence rate of 50% compared to 30% for the general population, yet one third of drivers will not be screened for risk factors due to a lack of insurance or primary care. With approximately 3.5 million commercial drivers nationally and correlation of CVD to increased motor vehicle accidents, fatalities, and excessive healthcare costs, addressing the care gap for this high-risk population is imperative.

METHODS

An evidence-based practice (EBP) project synthesized the literature and implemented CVD risk screening for commercial drivers examined in an occupational practice setting. Using the non-laboratory Framingham CVD risk score calculator, over 90% of drivers were screened during mandated medical examinations and provided education regarding modifiable risk factors during a 2-month period.

FINDINGS

Over 40% of commercial drivers were at high risk for CVD with 25% uninsured and 32% without primary care. The average CVD risk score was twice the general population's risk score, with obesity, hypertension, and smoking being the most common risk factors discussed.

CONCLUSIONS/APPLICATION TO PRACTICE

Incorporating CVD risk screening and education during opportune encounters is logical, efficient, and financially prudent. The EBP change supports occupational professionals' standards, and ongoing review of CVD screening guidelines with integration into practice provides health promotion and promotes public safety for these essential workers.

Does problem-based learning improve patient empowerment and cardiac risk factors in patients with coronary heart disease in a Swedish primary care setting? A long-term prospective, randomised, parallel single randomised trial (COR-PRIM)

OBJECTIVES

To investigate long-term effects of a 1-year problem-based learning (PBL) on self-management and cardiac risk factors in patients with coronary heart disease (CHD).

DESIGN

A prospective, randomised, parallel single centre trial.

SETTINGS

Primary care settings in Sweden.

PARTICIPANTS

157 patients with stable CHD completed the study. Subjects with reading and writing impairments, mental illness or expected survival less than 1 year were excluded.

INTERVENTION

Participants were randomised and assigned to receive either PBL (intervention) or home-sent patient information (control group). In this study, participants were followed up at baseline, 1, 3 and 5 years.

PRIMARY AND SECONDARY OUTCOMES

Primary outcome was patient empowerment (Swedish Coronary Empowerment Scale, SWE-CES) and secondary outcomes General Self-Efficacy Scale (GSES), self-rated health status (EQ-VAS), high-density lipoprotein cholesterol (HDL-C), body mass index (BMI), weight and smoking. Outcomes were adjusted for sociodemographic factors.

RESULTS

The PBL intervention group resulted in a significant improved change in SWE-CES over the 5-year period (mean (M), 39.39; 95% CI 37.88 to 40.89) compared with the baseline (M 36.54; 95% CI 35.40 to 37.66). PBL intervention group increased HDL-C level (M 1.39; 95% CI 1.28 to 1.50) compared with baseline (M 1.24; 95% CI 1.15 to 1.33) and for EQ-VAS (M 77.33; 95% CI 73.21 to 81.45) compared with baseline (M 68.13; 95% CI 63.66 to 72.59) while these outcomes remained unchanged in the control group. There were no significant differences in BMI, weight or scores on GSES, neither between nor within groups over time. The overall proportion of smokers was significantly higher in the control group than in the experimental group.

CONCLUSION

One-year PBL intervention had positive effect on patient empowerment, health status and HDL-C at a 5-year follow-up compared with the control group. PBL education aiming to improve patient empowerment in cardiac rehabilitation should account for sociodemographic factors.

The effect of educational intervention on self-care behavior in hypertensive older people: Applying the health belief model

BACKGROUND

Hypertension is a worldwide health issue. Increasing aging has given rise to the prevalence of this problem. Disease management using educational intervention based on theoretical frameworks is effective for influencing self-care behavior. The goal of this study is to investigate the effects of educational intervention on self-care behaviors that influence hypertension control among the elderly population during 2020 based on the health belief model.

MATERIALS AND METHODS

A quasi-experimental study was conducted on rural older people in Ardestan, Iran. Assessments were done before and after three educational intervention sessions with a control group. The random sampling has done on 99 hypertensive elderly people in two rural centers of Ardestan from 2019 to 2020. Awareness variables, components of the health belief model, and blood pressure were assessed before and three months after the intervention. Data analysis was done using descriptive and analytical statistics.

RESULTS

The study groups did not differ significantly in terms of the variables studied at the beginning of the study. After three months, the variables of awareness, self-care, and perceived sensitivity constructs, perceived severity, perceived benefits, and guide to action showed a significant rise in the experimental group compared to the control group. In addition, the effectiveness of educational intervention significantly increased self-care behavior in the experimental group.

CONCLUSIONS

Educational intervention based on the health belief model can be effective to reduce the barriers of self-care behaviors. In order to have a lasting change in behavior, the use of behavioral change patterns that ecologically take into account interpersonal, organizational, and social factors is suggested too.

Patient-centered education in dyslipidemia management: a systematic review

Background

Dyslipidemia management is crucial to reduce mortality and morbidity from cardiovascular diseases (CVDs). Patients must be educated and empowered to enable them to manage their own diseases. Various methods of patient education, such as patient-centered education (PCE) or non-PCE (such as didactic education or any traditional form of education), have been implemented.

Objective

To review and determine the effectiveness of PCE for dyslipidemia management compared with usual care. The primary outcome chosen was cholesterol level. Other measures, such as psychosocial or cognitive, behavioral, and other relevant outcomes, were also extracted. Additionally, underlying theories and other contributing factors that may have led to the success of the intervention were also reviewed and discussed.

Methods

We conducted searches in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, and Google Scholar from inception until April 2021. All studies involving randomized controlled trials were included. Study quality was assessed using the Critical Appraisal Skills Program (CASP) checklist specifically for randomized controlled trials.

Results

The search identified 8,847 records. Of these, 20 studies were eligible for inclusion. Interventions using a PCE approach were largely successful. Contributing factors extracted from the included studies were underlying theories, instant reward system, dietary education, collaborative care, duration of intervention with systematic follow-ups, social support, adherence assessment method, and usage of e-health.

Conclusions

PCE is successful in achieving the desired outcomes in dyslipidemia management. Future studies may incorporate the elements of PCE to improve the management of dyslipidemia in hospital or community settings where appropriate.

Design of a Randomized Placebo-Controlled Trial to Evaluate the Anti-inflammatory and Senolytic Effects of Quercetin in Patients Undergoing Coronary Artery Bypass Graft Surgery

Background: Following an acute coronary syndrome, patients display an elevated inflammatory profile, promoted in part by cellular senescence. For patients requiring a coronary artery bypass (CABG) surgery, exposure to the surgical intervention and cardiopulmonary bypass further exacerbate their residual inflammation. Experimental evidence identified quercetin, a natural senolytic drug, as a cardioprotective agent against inflammatory injuries. The Q-CABG study aims to explore the efficacy of quercetin to reduce inflammation, myocardial injury and senescence in patients undergoing CABG following an acute coronary syndrome.

Methods: Q-CABG is a phase II, prospectively registered, randomized, double-blind and placebo-controlled clinical trial. Recruited patients awaiting CABG surgery at the Montreal Heart Institute (n = 100) will be randomly assigned in a 1:1 ratio to receive either quercetin supplementation (500 mg twice daily) or placebo, starting 2 days before surgery and until the seventh postoperative day. The primary endpoint examines the effects of quercetin on blood inflammatory cytokines and markers of myocardial injury and senescence in this patient population. Blood samples will be taken at four time points: baseline, postoperative day 1, postoperative day 4 and at hospital discharge, or after a maximum of seven postoperative days. The secondary endpoint is the assessment of endothelial (dys) function by looking at ex vivo vascular reactivity and mRNA expression of endothelial cells from the wall of discarded segments of internal mammary artery.

Discussion: The preventive intake of quercetin supplementation may help limit the vigorous inflammatory response triggered by CABG and subsequent postoperative complications in patients suffering from an acute coronary syndrome. In an exploratory way, quercetin supplementation could also improve endothelial function by eliminating senescent vascular endothelial cells. The results of this trial should provide valuable information regarding a novel approach to improve biological, and potentially clinical, outcomes post CABG.

The Effects of Lifestyle Intervention Using the Modified Beliefs, Attitude, Subjective Norms, Enabling Factors Model in Hypertension Management: Quasi-Experimental Study

BACKGROUND

Hypertension is a serious health issue and a significant risk factor for cardiovascular disease and stroke. Although various health education models have been used to improve lifestyle in patients with hypertension, the findings have been inconsistent.

OBJECTIVE

This study aims to assess the effects of a lifestyle intervention program using a modified Beliefs, Attitude, Subjective Norms, Enabling Factors (BASNEF) model among nonadherent participants with hypertension in managing elevated blood pressure (BP) levels.

METHODS

This study reports a quantitative quasi-experimental research work, particularly using a repeated-measures design of the within-subjects approach on the 50 nonadherent patients who received a diagnosis of essential hypertension in Cebu, Philippines. The research participants received 5 sessions of training based on a modified BASNEF model. An adherence instrument was used as an evaluation platform. The first phase gathers participants' relevant profiles and background, and the final phase gathers participants' systolic BP, diastolic BP, heart rate, and adherence scores.

RESULTS

The results indicate that the phase 1 mean systolic readings (146.50, SD 19.59) differ significantly from the phase 4 mean systolic readings (134.92, SD 15.24). They also suggest that the lifestyle intervention based on session III or phase IV behavioral intention in the BASNEF model microgroup sessions positively affects BP readings among the research participants.

CONCLUSIONS

This study has established that the BASNEF model approach can be a good BP management technique.

Long-term effects (> 24 months) of multiple lifestyle intervention on major cardiovascular risk factors among high-risk subjects: a meta-analysis

Background

The evidence of the long-term effects of multiple lifestyle intervention on cardiovascular risk is uncertain. We aimed to summarize the evidence from randomized clinical trials examining the efficacy of lifestyle intervention on major cardiovascular risk factors in subjects at high cardiovascular risk.

Methods

Eligible trials investigated the impact of lifestyle intervention versus usual care with minimum 24 months follow-up, reporting more than one major cardiovascular risk factor. A literature search updated April 15, 2020 identified 12 eligible studies. The results from individual trials were combined, using fixed and random effect models, using the standardized mean difference (SMD) to estimate effect sizes. Small-study effect was evaluated, and heterogeneity between studies examined, by subgroup and meta-regression analyses, considering patient- and study-level variables.

Results

Small-study effect was not identified. Lifestyle intervention reduced systolic blood pressure modestly with an estimated SMD of − 0.13, 95% confidence interval (CI): − 0.21 to − 0.04, with moderate heterogeneity (I² = 59%), corresponding to a mean difference of approximately 2 mmHg (MD = − 1.86, 95% CI − 3.14 to − 0.57, p = 0.0046). This effect disappeared in the subgroup of trials judged at low risk of bias (SMD = 0.02, 95% CI − 0.08 to 0.11). For the outcome total cholesterol SMD was − 0.06, 95% CI − 0.13 to 0.00, with no heterogeneity (I² = 0%), indicating no effect of the intervention.

Conclusion

Lifestyle intervention resulted in only a modest effect on systolic blood pressure and no effect on total cholesterol after 24 months. Further lifestyle trials should consider the challenge of maintaining larger long-term benefits to ensure impact on cardiovascular outcomes.

Assessment of Interprofessional Collaborative Practices and Outcomes in Adults With Diabetes and Hypertension in Primary Care: A Systematic Review and Meta-analysis

Importance

Interprofessional collaborative practice (ICP), the collaboration of health workers from different professional backgrounds with patients, families, caregivers, and communities, is central to optimal primary care. However, limited evidence exists regarding its association with patient outcomes.

Objective

To examine the association of ICP with hemoglobin A1C (HbA1c), systolic blood pressure (SBP), and diastolic blood pressure (DBP) levels among adults receiving primary care.

Data Sources

A literature search of English language journals (January 2013-2018; updated through March 2020) was conducted using MEDLINE; Embase; Ovid IPA; Cochrane Central Register of Controlled Trials: Issue 2 of 12, February 2018; NHS Economic Evaluation Database: Issue 2 of 4, April 2015; Clarivate Analytics WOS Science Citation Index Expanded (1990-2018); EBSCOhost CINAHL Plus With Full Text (1937-2018); Elsevier Scopus; FirstSearch OAIster; AHRQ PCMH Citations Collection; ClinicalTrials.gov; and HSRProj.

Study Selection

Studies needed to evaluate the association of ICP (≥3 professions) with HbA1c, SBP, or DBP levels in adults with diabetes and/or hypertension receiving primary care. A dual review was performed for screening and selection.

Data Extraction and Synthesis

This systematic review and meta-analysis followed the PRISMA guideline for data abstractions and Cochrane Collaboration recommendations for bias assessment. Two dual review teams conducted independent data extraction with consensus. Data were pooled using a random-effects model for meta-analyses and forest plots constructed to report standardized mean differences (SMDs). For high heterogeneity (I2), data were stratified by baseline level and by study design.

Main Outcomes and Measures

The primary outcomes included HbA1c, SBP, and DBP levels as determined before data collection.

Results

A total of 3543 titles or abstracts were screened; 170 abstracts or full texts were reviewed. Of 50 articles in the systematic review, 39 (15 randomized clinical trials [RCTs], 24 non-RCTs) were included in the meta-analyses of HbA1c (n = 34), SBP (n = 25), and DBP (n = 24). The sample size ranged from 40 to 20 524, and mean age ranged from 51 to 70 years, with 0% to 100% participants being male. Varied ICP features were reported. The SMD varied by baseline HbA1c, although all SMDs significantly favored ICP (HbA1c <8, SMD = -0.13; P < .001; HbA1c ≥8  to < 9, SMD = -0.24; P = .007; and HbA1c ≥9, SMD = -0.60; P < .001). The SMD for SBP and DBP were -0.31 (95% CI, -0.46 to -0.17); P < .001 and -0.28 (95% CI, -0.42 to -0.14); P < .001, respectively, with effect sizes not associated with baseline levels. Overall I2 was greater than 80% for all outcomes.

Conclusions and Relevance

This systematic review and meta-analysis found that ICP was associated with reductions in HbA1c regardless of baseline levels as well as with reduced SBP and DBP. However, the greatest reductions were found with HbA1c levels of 9 or higher. The implementation of ICP in primary care may be associated with improvements in patient outcomes in diabetes and hypertension.

Lifestyle Intervention for Cardiovascular Disease Risk Factors in Jeddah, Saudi Arabia

Background Cardiovascular disease (CVD) remains the major cause of global mortality. Applying a comprehensive interventional program may reduce the incidence of cardiovascular disease and its complications. Objective This study compared the effects of a three-month intervention involving lifestyle modification and physical activity with standard care in women ≥30 years having a moderate to high risk of CVD, with respect to improving physical activity and cardiovascular disease risk factors at the National Guard Residential City in Jeddah, Saudi Arabia, in 2015. Methods The effects of this community-based lifestyle program were assessed through a randomized controlled trial from January 1st to September 6th, 2015. Women in the intervention group (n = 31) received health education, exercise training, and diet counselling as individuals and in groups according to the participant's risk. Women in the control group (n = 28) received one health education session at the screening site. The primary outcome was the proportion of women with moderate Framingham risk scores (FRS) reducing their risk by 10% and the proportion of women with high FRS reducing their risk by 25%. The secondary outcome was the proportion of women reducing their risk by ≥1 risk category. Results The mean participant age was 42 ± 8 years. At three-month's follow-up, reductions were greater in the intervention group and the difference between groups was statistically significant (p < 0.05). Lifestyle intervention program significantly reduced systolic blood pressure (-9.2 mmHg), blood glucose (-45 mg/dL) and Framingham risk score (-13.6). Linear regression analysis revealed a significant improvement in the Framingham risk score (p < 0.01). Conclusion In a population of women with moderate-to-high risk of CVD, a personalized lifestyle modification program showed positive association in improving the 10-year cardiovascular Framingham risk score after three months.

Using Social Marketing to Reduce Salt Intake in Iran

Objectives: WHO has recommended that the average salt intake must be <5 grams per day. However, people consume salt much more in many countries. In this study, we design and implement an intervention based on social marketing model to reduce salt consumption in Yasuj, Iran. Materials and Methods: This study employed a quasi-experimental pretest-posttest with control group design which consisted of a formative research (qualitative-quantitative) and an interventional phase. To collect the qualitative data, six focus group discussions by participating of 66 people were established. The qualitative data were analyzed manually using directed content analysis. In quantitative study, 166 people aged 25-50 years completed a KAP questionnaire, and their average salt intake was determined through measuring sodium in their urine sample. By analyzing the data, marketing mix components were determined for designing an intervention. An educational package (including posters for installing in the kitchen, pamphlets, phone counseling, four educational classes, and brief interventions done by physicians and other health personnel) focused on reducing salt intake and using alternatives was developed. For one month, program was implemented for intervention group. Two months later, KAP survey and measuring the urine sodium were repeated for intervention and control groups. The data was compared for two groups, before and after the intervention by using independent t-test, paired t-tests and repeated measures ANOVA. Results: The qualitative findings showed that most participants agreed that the salt intake was high in Iran. Most of them recommended home-based and family-driven strategies to reduce salt intake, offered using healthier alternatives for salt, and recognized physicians and health care providers in healthcare facilities as the most important to encourage people to reduce salt intake. After the intervention, the mean and standard deviation of KAP were improved significantly in intervention group. The mean salt intake decreased significantly by 3.01 ± 2.38 in the intervention group and repeated measures ANOVA showed significant change over time (P < 0.001) and a significant difference between two groups (P = 0.04)_. Also, the interaction between time and group was significant (P = 0.001). Conclusion: The mean salt intake among the study population was approximately three times more than the level recommended by the WHO. The social marketing-based intervention succeeded in reducing the salt intake of the study subjects by ~3 grams on average.

Participant Evaluation of a Prediabetes Intervention Program Designed for Rural Adults

The type 2 diabetes epidemic is a global crisis threatening the health and economies of many nations. This study aimed to evaluate a prediabetes intervention program designed for rural adults in southwestern Ontario based on the feedback of participants. Rural adults with prediabetes were referred by physicians to an intervention program developed to assist with unique barriers rural adults face related to the built environment and socioeconomic status when adopting a healthy lifestyle. After 6 monthly education sessions offered by a dietitian and a nurse, participants completed a questionnaire to share their program experience. In addition, 6 focus groups consisting of 5-9 participants were conducted to assess program acceptability, feasibility, and practicality. Of 49 enrolled, 35 participants aged 60.8 ± 7.1 (mean ± SD) evaluated the program. Participants reported finding the program to be acceptable, feasible, and practical due to the interactive nature of the sessions, the group setting and the availability of health professionals. This prediabetes lifestyle intervention program was perceived as successfully addressing rural adults' needs in terms of adopting a healthy lifestyle. Feedback received through program evaluation, which included a participant experience survey and focus groups has helped improve this program and may benefit other prediabetes education intervention programs.

A Scoping Review of Positive Lifestyle and Wellness Interventions to Inform the Development of a Comprehensive Health Promotion Program: "HealthPro"

Background. Lifestyle medicine has emerged as a transformational force in mainstream health care. Numerous health promotion and wellness programs have been created to facilitate the adoption of increased positive, modifiable health behaviors to prevent and lessen the effects of chronic disease. This article provides a scoping review of available health promotion interventions that focus on healthy adult populations in the past 10 years. Methods. We conducted a scoping review of the literature searching for health promotion interventions in the past 10 years. Interventions were limited to those conducted among healthy adults that offered a face-to-face, group-based format, with positive results on one or more health outcomes. We then developed a new health promotion intervention that draws on multiple components of included interventions. Results. Fifty-eight articles met our inclusion criteria. Physical activity was the primary focus of a majority (N = 47) of articles, followed by diet/nutrition (N = 40) and coping/social support (N = 40). Conclusions. Efficacious health promotion interventions are critical to address the prevention of chronic disease by addressing modifiable risk factors such as exercise, nutrition, stress, and coping. A new intervention, discussed is this article, provides a comprehensive approaches to health behavior change and may be adapted for future research.

Effectiveness of an intensive intervention to improve lifestyles in people with intermediate cardiovascular risk (DATE study): Study protocol for a randomized controlled trial

AIM

The aim of this study was to evaluate the effectiveness of an intensive intervention led by primary care nurses for lifestyle modification among people with intermediate cardiovascular risk.

BACKGROUND

Cardiovascular diseases may be prevented by adopting healthy lifestyles. Interventions focused on populations at risk are more efficient than those aimed at the general population. More than 50 per cent of cardiovascular events occur in people with intermediate cardiovascular risk, but only a few studies have targeted this population.

DESIGN

A randomized controlled trial approved in January 2017.

METHODS

We will recruit 208 participants aged 35-74 years who have intermediate cardiovascular risk. They will be selected by consecutive sampling and will be randomized into a control group or intervention group. Individual standardized brief counselling on healthy lifestyles will be provided to both groups. Additionally, individuals from the intervention group will receive four weekly group sessions focusing on cardiovascular risk, healthy diet, moderation in alcohol consumption, daily physical activity, stress management and smoking cessation and two motivational follow-up calls. The primary outcome will be the lifestyle modification measured by total steps recorded by a pedometer, total score on the Mediterranean Diet Adherence Screener and percentage of current smokers.

DISCUSSION

This study will allow us to investigate whether an intensive intervention based on a multifactorial group approach is more effective in lifestyle modification than individual standardized brief counseling among adults with intermediate cardiovascular risk. Our results could lead to the establishment of new strategies for cardiovascular risk management.

The Effect of Interdisciplinary Interventions on Risk Factors for Lifestyle Disease: A Literature Review

Interventions that comprise interdisciplinary collaboration including behavioral elements are effective in addressing lifestyle disease risk factors. However, it is not known how best to conduct this collaboration for sustainable change. The aim of this study was to systematically examine the evidence for the effects of interdisciplinary interventions on lifestyle disease risk factors including weight, lipid levels, glycemic control, and blood pressure. To do so, a systematic review of the literature was conducted using the databases Scopus, Medline, and Web of Science (all years to September 2014). Eighteen articles describing 16 studies of interdisciplinary interventions were identified. Consistent results were found for effects on weight loss but not for effects on blood lipids, blood glucose, and blood pressure. Effective interventions involved collaborations between dieticians, exercise physiologists, and psychologists and incorporated intensive initial participant engagement. Few studies investigated the long-term effect of interventions, but where this was done, the maintenance of favorable changes required ongoing participant support. Current evidence suggests that interdisciplinary interventions are effective in promoting weight loss and that ongoing support of participants is key to maintaining results beyond initial study duration. Future studies should examine long-term effects in pragmatic trials that address translation to practice.
