Community-based lifestyle modification workforce: an underutilised asset for cardiovascular disease prevention

Unhealthy changes in eating habits cause acute onset hypertension in the normotensive community-dwelling elderly-3 years cohort study

The aim of this study was to determine what lifestyle changes can predict acute onset hypertension in the normotensive community-dwelling elderly.This study targeted elderly people enrolled in National Health Insurance in Fukushima Prefecture, Japan. The subjects were 24,490 people who took all of the specific health examination conducted by National Health Insurance in fiscal years 2013, 2014, and 2015 continuously and had a recorded systolic blood pressure (BP) <130 mm Hg and diastolic BP <85 mm Hg in the first 2 fiscal years. We examined their lifestyle changes for the first 2 fiscal years using the questionnaires given at the health examination. Multivariate Poisson regression analysis was conducted to examine the relationship between new-onset hypertension observed at the last examination and unhealthy lifestyle changes.The mean age of the subjects was 61.5 ± 8.2 years old at baseline. We observed new-onset hypertension in 1.062 subjects at the last examination. Of the study subjects, 12,027 (49.1%) answered to having at least one of the items of unhealthy lifestyle change in the questionnaire. In the multivariate logistic regression, eating supper before bedtime showed a significant increase in the risk ratio for acute onset hypertension (risk ratio 1.27, 95% confidence interval, 1.01-1.58).This study indicated that eating before bedtime is a risk factor of new-onset hypertension in the normotensive community-dwelling elderly. Adequate health guidance to avoid unhealthy lifestyle changes is required even in normotensive people as this hypertension is preventable.

Implementation of cardiovascular disease prevention in primary health care: enhancing understanding using normalisation process theory

Background

The reorientation of primary health care towards prevention is fundamental to addressing the rising burden of chronic disease. However, in Australia, cardiovascular disease prevention practice in primary health care is not generally consistent with existing guidelines. The Model for Prevention study was a whole-of-system cardiovascular disease prevention intervention, with one component being enhanced lifestyle modification support and addition of a health coaching service in the general practice setting. To determine the feasibility of translating intervention outcomes into real world practice, implementation work done by stakeholders was examined using Normalisation Process Theory as a framework.

Methods

Data was collected through interviews with 40 intervention participants and included general practitioners, practice nurses, practice managers, lifestyle advisors and participants. Data analysis was informed by normalisation process theory constructs.

Results

Stakeholders were in agreement that, while prevention is a key function of general practice, it was not their usual work. There were varying levels of engagement with the intervention by practice staff due to staff interest, capacity and turnover, but most staff reconfigured their work for required activities. The Lifestyle Advisors believed staff had varied levels of interest in and understanding of, their service, but most staff felt their role was useful. Patients expanded their existing relationships with their general practice, and most achieved their lifestyle modification goals.

While the study highlighted the complex nature of the change required, many of the new or enhanced processes implemented as part of the intervention could be scaled up to improve the systems approach to prevention. Overcoming the barriers to change, such as the perception of CVD prevention as a ‘hard sell’, is going to rely on improving the value proposition for all stakeholders.

Conclusions

The study provided a detailed understanding of the work required to implement a complex cardiovascular disease prevention intervention within general practice. The findings highlighted the need for multiple strategies that engage all stakeholders. Normalisation process theory was a useful framework for guiding change implementation.

Developing research priorities in Australian primary health care: a focus on nutrition and physical activity

Research priority setting is an important component of research planning, particularly when research options exceed available resources. This study identified the research priorities for supporting healthy lifestyle behaviours in the Australian primary healthcare setting. A five-step stakeholder engagement process was undertaken. Ten stakeholder organisations participated in the process, including patient representatives, health professional associations, health educators, researchers, government advisors and policymakers. Each organisation was asked to provide up to three research questions deemed as a priority. Research questions were critically appraised by the project team for answerability, sustainability, effectiveness, potential for translation and potential to affect disease burden. A blinded scoring system was used to rank the appraised questions, with higher scores indicating higher priority (range of scores possible 87-156). Thirteen unique research questions were submitted by stakeholders and achieved a range of scores from 87 to 139 points. The highest scoring research questions focused on: (i) the effectiveness of different health professionals at facilitating healthy lifestyle behaviours; (ii) the effect of health literacy on behaviour change; and (iii) cost-benefit analysis of healthy lifestyle promotion in primary health care. These priorities can be used to ensure future research projects directly align with the needs and preferences of research end-users.
