Patient-planetary health co-benefit prescribing in a circumpolar health region: a qualitative study of physician voices from the Northwest Territories, Canada

Por: Redvers · N. · Hartmann-Boyce · J. · Tonkin-Crine · S.
Background

Despite climate change being described as a code red for humanity, health systems have been particularly slow in both climate mitigation and adaptation responses. The effects of climate change on health and health systems will not be felt equally, with underserved and marginalised communities disproportionately impacted. The circumpolar region is warming at 3–4 times the global rate, amplifying already existing socioeconomic barriers and health inequities, with particular amplified effects for the substantial Indigenous population in the area.

Objectives and setting

We therefore sought to explore perspectives of physicians around patient-planetary health (P-PH) co-benefit prescribing in a circumpolar region in the Northwest Territories (NWT), Canada, known to be one of the ground zero levels for climate change.

Methods

Thirteen semi-structured physician interviews were carried out in the NWT region between May 2022 and March 2023 using purposive sampling. Interviews were transcribed verbatim and reflexive thematic analysis was carried out to identify key themes.

Results

There were three main themes identified including (1) current healthcare system does not support planetary health, (2) supporting patient-planetary health is currently difficult for clinicians and (3) considering change in the NWT to support patient-planetary health. Participants noted key opportunities to move planetary health forward, with the NWT having the potential to be an innovative model for planetary health-informed change for other health systems.

Conclusion

The NWT health system has unique features due to its rural and remote nature and smaller population base. Despite this, our study identified some key opportunities for advancing P-PH co-benefit efforts. The identified opportunities may be considered in future intervention, organisational change and policy-making efforts with potential relevance in other settings.

Fibre-rich Foods to Treat Obesity and Prevent Colon Cancer trial study protocol: a randomised clinical trial of fibre-rich legumes targeting the gut microbiome, metabolome and gut transit time of overweight and obese patients with a history of noncancerou

Introduction

Recently published studies support the beneficial effects of consuming fibre-rich legumes, such as cooked dry beans, to improve metabolic health and reduce cancer risk. In participants with overweight/obesity and a history of colorectal polyps, the Fibre-rich Foods to Treat Obesity and Prevent Colon Cancer randomised clinical trial will test whether a high-fibre diet featuring legumes will simultaneously facilitate weight reduction and suppress colonic mucosal biomarkers of colorectal cancer (CRC).

Methods/design

This study is designed to characterise changes in (1) body weight; (2) biomarkers of insulin resistance and systemic inflammation; (3) compositional and functional profiles of the faecal microbiome and metabolome; (4) mucosal biomarkers of CRC risk and (5) gut transit. Approximately 60 overweight or obese adults with a history of noncancerous adenomatous polyps within the previous 3 years will be recruited and randomised to one of two weight-loss diets. Following a 1-week run-in, participants in the intervention arm will receive preportioned high-fibre legume-rich entrées for two meals/day in months 1–3 and one meal/day in months 4–6. In the control arm, entrées will replace legumes with lean protein sources (eg, chicken). Both groups will receive in-person and written guidance to include nutritionally balanced sides with energy intake to lose 1–2 pounds per week.

Ethics and dissemination

The National Institutes of Health fund this ongoing 5-year study through a National Cancer Institute grant (5R01CA245063) awarded to Emory University with a subaward to the University of Pittsburgh. The study protocol was approved by the Emory Institutional Review Board (IRB approval number: 00000563).

Trial registration number
