The content of diet and physical activity consultations with older adults in primary care

Associations of sedentary behavior and screen time with biomarkers of inflammation and insulin resistance

Sedentary behavior (SB) has been linked to risk factors of cardiometabolic disease, with inconsistent findings reported in the literature. We aimed to assess the associations of SB with multiple biomarkers of inflammation and insulin resistance in adults. Domain-specific SB, sitting time and moderate-to-vigorous physical activity (MVPA) were measured in 78 adults (mean ± SD 52.0 ± 10.8 y). Body fat percentage (BF%) was assessed using multi-frequency bioelectrical impedance. A blood draw assessed glucose, insulin, C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), leptin, and adiponectin. Adiponectin-leptin ratio (ALR), homeostasis model assessment of insulin resistance (HOMA-IR) and beta-cell function (HOMA-β) were calculated. Multivariable linear regression analyses, controlling for age, sex, MVPA, and BF%, were used to assess associations. After adjustment for age, sex and MVPA, total SB (7.5 ± 2.5 h/day) was positively associated with leptin, insulin, HOMA-IR, HOMA-β (Standardized Beta (β) range 0.21-0.32) and negatively associated with ALR (β = -0.24, p < 0.05 for all). Similarly, total sitting time (7.2 ± 2.9 h/day) was associated with TNF-α (β = 0.22) and ALR (β = -0.26). These associations were attenuated to non-significance after adjustment for BF%. Leisure screen time was detrimentally associated with IL-6 (β = 0.24), leptin (β = 0.21), insulin (β = 0.37), HOMA-IR (β = 0.37), and HOMA-β (β = 0.34), independent of age, sex and MVPA (p < 0.05 for all). Only the associations with insulin (β = 0.26), HOMA-IR (β = 0.26), and HOMA-β (β = 0.23) remained significant after further controlling BF% (p < 0.05). Self-reported SB is associated with biomarkers of inflammation and insulin resistance, independent of MVPA, and in some cases BF%.

Delivering brief physical activity interventions in primary care: a systematic review

BACKGROUND

Physical activity (PA) brief interventions (BIs) involving screening and/or advice are recommended in primary care but frequency of delivery is unknown.

AIM

To examine the extent to which PA BIs are delivered in primary care, and explore factors associated with delivery, receipt, and patient receptivity.

DESIGN AND SETTING

A mixed-methods systematic review of studies conducted worldwide, with a narrative synthesis of results.

METHOD

CINAHL, EMBASE, MEDLINE, and APA PsycINFO index databases were searched for qualitative and quantitative studies, dating from January 2012 to June 2020, that reported the level of delivery and/or receipt of PA BIs in primary care, and/or factors affecting delivery, receipt, and patient receptivity. Quality was assessed using the Mixed Methods Appraisal Tool. Attitudes towards and barriers to delivery were coded into the Theoretical Domains Framework and the Capability, Opportunity, and Motivation Behaviour model.

RESULTS

After screening a total of 13 066 records, 66 articles were included in the review. The extent of PA screening and advice in primary care varied widely (2.4%-100% and 0.6%-100%, respectively). PA advice was delivered more often to patients with a higher body mass index, lower PA levels, and/or more comorbidities. Barriers - including a lack of time and training/guidelines - remain, despite recommendations from the World Health Organization and National Institute for Health and Care Excellence that PA advice should be provided in primary care. Few studies explored patients' receptivity to advice.

CONCLUSION

PA BIs are not delivered frequently or consistently in primary care. Addressing barriers to delivery through system-level changes and training programmes could improve and increase the advice given. Understanding when patients are receptive to PA interventions could enhance health professionals' confidence in their delivery.

Physical Activity Promotion: A Systematic Review of The Perceptions of Healthcare Professionals

Physical activity (PA) is a cost-effective and non-pharmacological foundation for the prevention and management of chronic and complex diseases. Healthcare professionals could be viable conduits for PA promotion. However, the evidence regarding the effectiveness and benefits of the current forms of PA promotion are inconclusive. Healthcare professionals' perceptions on key determinants impact on the optimum promotion of PA were explored in this review. Thirty-four (34) studies were identified after systematically searching seven databases for peer-reviewed articles published within the last decade. PA advice or counselling was the most recorded form of PA promotion, limited counselling time was the most reported obstacle while providing incentives was viewed as a key facilitator. There is widespread consensus among healthcare professionals (HCPs) on some aspects of PA promotion. Utilisation of all PA promotional pathways to their full potential could be an essential turning point towards the optimal success of PA promotional goals. Hence, strategies are required to broaden chronic disease treatment methods to include preventive and integrative PA promotion approaches particularly, between frontline HCPs (e.g., GPs) and PA specialists (e.g., EPs). Future studies could explore the functionality of GP to EP referral pathways to determining what currently works and areas requiring further development.

Discussing lifestyle behaviors: perspectives and experiences of general practitioners

Background: Initiatives aimed at increasing participation in preventive health behaviors has been identified as a priority for addressing the increasing incidence of non-communicable chronic disease. General practice is an existing network that can be leveraged to intervene and promote messages for health behavior change. We aimed to explore the extent to which ‘lifestyle’ behaviors are discussed by general practitioners (GPs) with their patients in their practices, and the context and content of these discussions.

Methods: GPs (N = 26) practising in Australian clinics participated in semi-structured interviews. Data were analyzed using an inductive thematic analysis.

Results: Results showed discussions of lifestyle behaviors were brief, but relatively frequent and often initiated by the GP. GPs generally provided basic advice and education that was often ad-hoc and in reaction to prompts from the patient. GPs recognized the importance of addressing lifestyle behaviors in practice, but also highlighted substantive barriers that limit the initiation of these discussions. These included patient readiness for change, patient acceptance and openness, patient accountability and responsibility, patient background factors, GPs’ role and knowledge, GP financial implications, GP-patient relationship, and lack of time.

Conclusions: Current findings provide important preliminary knowledge on the extent to which Australian GPs discuss lifestyle behavior change with patients during routine consultations, the context and content of these discussions, and barriers to initiating these discussions. Further research should seek to gain a better understanding of barriers and identify strategies to mitigate their impact. This might maximize the potential for GPs to promote adaptive lifestyle behavior change for improving patient health.

Moving healthcare professionals - a whole system approach to embed physical activity in clinical practice

BACKGROUND

Healthcare professionals are key informants to support individual behaviour change, and although there has been some progress in empowering clinicians to promote physical activity and health at work, an effective strategy overarching the whole medical educational journey is still lacking. This report provides an overview from the Moving Healthcare Professionals programme (MHPP), a whole-system educational approach to embed prevention and physical activity promotion into clinical practice.

METHODS

The MHPP model integrates educational resources into three core domains of medical education: undergraduate education, postgraduate education and continuing professional development. The interventions are designed to spiral through existing educational approaches rather than as additional special study modules or bolt-on courses, thus reducing self-selection bias in exposure. Interventions include spiral undergraduate education materials, e-learning, embedded post-graduate resources and face-to-face peer-to-peer education.

RESULTS

To date the MHPP model has been applied in two key areas, physical activity and health and work. The physical activity programme in a partnership between Public Health England and Sport England has delivered face-to-face training to 17,105 healthcare professionals, embedded materials in almost three quarters of English medical schools and overseen > 95,000 e-learning modules completed over two and half years. Evaluation of the individual elements of the model is ongoing and aims to show improvements in knowledge, skills and practice. Further evaluation is planned to assess patient impact.

CONCLUSIONS

The MHPP model offers a coherent whole-system approach to embed public health action into existing healthcare education models, and as such provides a framework for rapid change as well as upstream implementation to support the clinicians of today and tomorrow.

Exercise for Multimorbid Patients in Primary Care: One Prescription for All?

The purpose of this article was to discuss guidelines for the management of the most prevalent chronic diseases treated by primary care physicians (PCPs) in order to identify the best exercise regimen for each clinical population, and to provide preliminary guidance for primary care providers on exercise counselling in the 'real-world' context of multimorbidity. After a search of the PubMed electronic database, the 11 most prevalent conditions currently treated by PCPs were identified. The recommendations provided by recognised learned/scientific societies for the management of each disease were then examined and any recommendations involving physical activity and exercise were identified. It was found that the best exercise regimen (i.e. exercise type, intensity, duration, and frequency) was very similar across chronic diseases, which suggests that elaborating and implementing a standardised, minimum exercise guideline for multimorbid patients in primary care may be an alternative approach to time-costly individualised exercise prescriptions. Based on this finding, I propose an example of standardised, cross-disease exercise prescription, and discuss how such a prescription could be operationalised by PCPs in their routine clinical practice.

The Role of Primary Care Providers in Encouraging Older Patients to Change Their Lifestyle Behaviors

OBJECTIVES

This study sought to identify older patients' perceptions of primary care providers' influence on their likelihood of improving diet and physical activity.

METHODS

104 adults ages 65 and older were interviewed immediately following a routine primary care visit about their plans and motivations for behavior change and how their clinic visit would influence their likelihood of making lifestyle changes. All interviews were recorded, transcribed and analyzed using a constant comparison approach.

RESULTS

Participants reported that their providers influence their health behaviors by developing strong relationships, addressing concerns and encouraging change, and providing concrete instruction. When providers did not discuss diet or physical activity, or mentioned these topics only briefly, participants often perceived the message that they should continue their current behaviors.

CONCLUSIONS

Whether and how diet and physical activity are discussed in primary care influences the likelihood that older adults will make changes in these behaviors.

CLINICAL IMPLICATIONS

These findings highlight the need for a patient-centered counseling approach and caution providers to think twice before omitting discussion of the need for lifestyle change.

Key Strategies for Physical Activity Interventions Among Older Women: Process Evaluation of a Clinical Trial

PURPOSE

To describe strategies salient to physical activity (PA) initiation and maintenance among older women who participated in a clinical trial that tested a PA intervention.

DESIGN

A descriptive phenomenological, qualitative design for a process evaluation of a successful clinical trial.

SETTING

Senior primary care clinics associated with a large medical center in a southern state.

PARTICIPANTS

A total of 20 older women at least 60 years without advanced frailty.

METHOD

Purposive sampling using maximum variation technique was used to select participants. A semi-structured interview guide facilitated individual, in-depth interviews lasting 45 to 90 minutes. Narratives were analyzed using content analysis with constant comparison technique to summarize the data.

RESULTS

Eight African American and 12 white older women with a mean age of 68 from control and intervention arms participated. Five central themes described salient strategies to promote and maintain PA: sensed benefits, motivation, and self-efficacy were central to success, while a reduction in barriers was essential before maintaining PA. The last theme, a life-changing awareness indicated that PA had become a shared value. An explanatory model describing interrelationships is presented.

CONCLUSIONS

This study suggests key strategies to include in PA interventions with older women. An unexpected finding was that PA became a shared value, an action promoted by the Culture of Health initiative to improve population health and well-being.

Primary Care Providers' Level of Preparedness for Recommending Physical Activity to Adults With Disabilities

INTRODUCTION

Adults with disabilities are more likely to be physically inactive than those without disabilities. Although receiving a health care provider recommendation is associated with physical activity participation in this population, there is little information on factors associated with primary care providers recommending physical activity to patients with disabilities.

METHODS

We used 2014 DocStyles data to assess primary care provider characteristics and perceived barriers to and knowledge-related factors of recommending physical activity to adult patients with disabilities, by how prepared primary care providers felt in making recommendations. We used log-binomial regression to estimate adjusted prevalence ratios (PRs) and 95% confidence intervals (CIs) between recommending physical activity at most visits and primary care provider characteristics and preparedness.

RESULTS

Most primary care providers strongly (36.3%) or somewhat (43.3%) agreed they felt prepared to recommend physical activity to patients with disabilities. We found significant trends between preparedness and primary care provider age (P = .001) and number of patients with disabilities seen per week (P < .001). Half (50.6%) of primary care providers recommend physical activity to patients with disabilities at most visits. Primary care providers who strongly agreed (adjusted PR, 1.74; 95% CI, 1.44-2.09) or somewhat agreed (adjusted PR, 1.36; 95% CI, 1.22-1.65) they felt prepared were more likely to recommend physical activity at most visits compared with those who were neutral or disagreed.

CONCLUSION

Primary care providers are more likely to recommend physical activity to patients with disabilities regularly if they feel prepared. Understanding factors and barriers associated with preparedness can help public health programs develop and disseminate resources for primary care providers to promote physical activity among adults with disabilities.

Self-Care for the Prevention and Management of Cardiovascular Disease and Stroke: A Scientific Statement for Healthcare Professionals From the American Heart Association

Self-care is defined as a naturalistic decision-making process addressing both the prevention and management of chronic illness, with core elements of self-care maintenance, self-care monitoring, and self-care management. In this scientific statement, we describe the importance of self-care in the American Heart Association mission and vision of building healthier lives, free of cardiovascular diseases and stroke. The evidence supporting specific self-care behaviors such as diet and exercise, barriers to self-care, and the effectiveness of self-care in improving outcomes is reviewed, as is the evidence supporting various individual, family-based, and community-based approaches to improving self-care. Although there are many nuances to the relationships between self-care and outcomes, there is strong evidence that self-care is effective in achieving the goals of the treatment plan and cannot be ignored. As such, greater emphasis should be placed on self-care in evidence-based guidelines.

Unravelling effectiveness of a nurse-led behaviour change intervention to enhance physical activity in patients at risk for cardiovascular disease in primary care: study protocol for a cluster randomised controlled trial

Background

Self-management interventions are considered effective in patients with chronic disease, but trials have shown inconsistent results, and it is unknown which patients benefit most. Adequate self-management requires behaviour change in both patients and health care providers. Therefore, the Activate intervention was developed with a focus on behaviour change in both patients and nurses. The intervention aims for change in a single self-management behaviour, namely physical activity, in primary care patients at risk for cardiovascular disease. The aim of this study is to evaluate the effectiveness of the Activate intervention.

Methods/design

A two-arm cluster randomised controlled trial will be conducted to compare the Activate intervention with care as usual at 31 general practices in the Netherlands. Approximately 279 patients at risk for cardiovascular disease will participate. The Activate intervention is developed using the Behaviour Change Wheel and consists of 4 nurse-led consultations in a 3-month period, integrating 17 behaviour change techniques. The Behaviour Change Wheel was also applied to analyse what behaviour change is needed in nurses to deliver the intervention adequately. This resulted in 1-day training and coaching sessions (including 21 behaviour change techniques). The primary outcome is physical activity, measured as the number of minutes of moderate to vigorous physical activity using an accelerometer. Potential effect modifiers are age, body mass index, level of education, social support, depression, patient-provider relationship and baseline number of minutes of physical activity. Data will be collected at baseline and at 3 months and 6 months of follow-up. A process evaluation will be conducted to evaluate the training of nurses, treatment fidelity, and to identify barriers to and facilitators of implementation as well as to assess participants’ satisfaction.

Discussion

To increase physical activity in patients and to support nurses in delivering the intervention, behaviour change techniques are applied to change behaviours of the patients and nurses. Evaluation of the effectiveness of the intervention, exploration of which patients benefit most, and evaluation of our theory-based training for primary care nurses will enhance understanding of what works and for whom, which is essential for further implementation of self-management in clinical practice.

Older Patients' Recall of Lifestyle Discussions in Primary Care

Despite the known benefits of engaging in healthy diet and physical activity across the life span, suboptimal diet and physical inactivity are pervasive among older adults. While health care providers can promote patients' engagement in health behaviors, patient recall of recommendations tends to be imperfect. This study sought to better understand older adults' recall of dietary and physical activity discussions in primary care. One hundred and fifteen adults aged 65 and older were interviewed immediately following a routine primary care visit on whether and what they recalled discussing pertaining to diet and physical activity. Compared against transcripts, most patients accurately recalled their diet and physical activity discussions. The inclusion of a recommendation, and for diet discussions longer duration, increased the likelihood of patient recall for these health behavior discussions. These findings suggest that specific recommendations and an extra minute of discussion, at least for dietary discussions, increase the likelihood of accurate patient recall.
