Adherence to dietary guidelines and associated factors among rural Australian cancer survivors: a cross-sectional study.

PURPOSE: This study aimed to explore levels of adherence to dietary guidelines, and factors associated with dietary guideline adherence, among rural Australian cancer survivors. METHODS: A cross-sectional study was undertaken. We recruited a convenience sample of adults with cancer who attended the chemotherapy day unit or allied health appointments at a rural hospital in Baw Baw Shire, Victoria, Australia, between August 2017 and December 2021. Dietary guideline adherence was assessed by cross-referencing participants' responses to an adapted version of the Dietary Questionnaire for Epidemiological Studies with dietary recommendations in Australian dietary guidelines. Binary logistic regression was used to assess factors associated with dietary guideline adherence for fruits and whole red meats. RESULTS: There were 107 rural cancer survivors (median age, 67 years). Dietary guideline adherence was highest for alcohol (88%) followed by whole red meats (63%), fruits (56%), processed red meats (24%), cereals/breads/grains (7%), and vegetables (4%). Relative to those aged < 65 years, 65-74-year-olds had 5.7-fold greater odds (adjusted odds ratio (aOR) = 5.74, 95% confidence interval (CI) = 1.91-17.17) of adhering to the dietary guideline for fruits. Relative to those who had completed/ceased treatment, participants who were currently receiving treatment had 78% lower odds (aOR = 0.22, 95% CI = 0.09-0.59) of adhering to the dietary guideline for fruits. CONCLUSION: This study contributes preliminary data on adherence to dietary guidelines and associated factors among rural Australian cancer survivors. Dietary guideline adherence varied across food groups and was mostly low, albeit not markedly worse than Australia's national population for the fruits and vegetables groups. The mostly low adherence in our sample suggests a potential need to increase provision of dietary information, supportive care screening, and, wherever necessary, dietetics referrals, assessments, and interventions among rural cancer survivors. Larger, longitudinal studies of adherence to dietary guidelines and/or tailored, cancer-specific dietary recommendations should be undertaken in future.

Physical activity, obesity, and quality of life among rural Australian cancer survivors: a cross-sectional study.

PURPOSE: We aimed to describe physical activity (PA), obesity, and quality of life (QoL) among rural Australian cancer survivors, assess whether total and item-specific QoL are associated with sufficient PA and obesity, and assess whether PA and obesity interact with respect to QoL. METHODS: In a cross-sectional study, convenience sampling was used to recruit adult cancer survivors via a chemotherapy day unit and allied health professionals at a rural hospital in Baw Baw Shire, Australia. Exclusion criteria were acute malnutrition and end-of-life care. PA and QoL were measured using Godin-Shephard and 7-item Functional Assessment of Cancer Therapy (FACT-G7) questionnaires, respectively. Factors associated with total and item-specific QoL were assessed via linear and logistic regression, respectively. RESULTS: Among 103 rural cancer survivors, the median age was 66 years, 35% were sufficiently physically active, and 41% presented with obesity. Mean/median total QoL scores were 17 on the FACT-G7 scale (0-28; higher scores indicate better QoL). Sufficient PA was associated with better QoL ([Formula: see text]=2.29; 95% confidence interval [CI] = 0.26, 4.33) and more energy (odds ratio [OR] = 4.00, 95% CI = 1.48, 10.78) while obesity was associated with worse QoL ([Formula: see text]=-2.09; 95% CI = -4.17, -0.01) and more pain (OR = 3.88, 95% CI = 1.29, 11.68). The PA-obesity interaction was non-significant (p-value = 0.83). CONCLUSIONS: This is the first known study conducted among rural survivors of any cancer to find sufficient PA and obesity are associated with better and worse QoL, respectively. PA, weight management, and QoL-including energy and pain-should be considered when targeting and tailoring supportive care interventions for rural cancer survivors.

Factors associated with physical activity levels in people with venous leg ulcers: A multicentre, prospective, cohort study.

Increasing levels of physical activity among people with venous leg ulcers (VLUs) can potentially reduce the health cost burden, improve functional aspects of patients' lives and increase ulcer healing rates. The aim of this study was to investigate factors associated with physical activity levels in patients with VLUs. Data from 2016 to 2017 Aspirin for Venous Leg Ulcer cohort study were analysed for the present study. Ninety participants were recruited from 5 outpatient specialist wound clinics across Victoria, Australia between August 2016 and April 2017. There was a statistically significant association between diabetes and physical activity, with a higher proportion of people with type 2 diabetes in the sedentary category. Further, there was a statistically significant association between patient-reported VLU education and physical activity levels. An indirect advantage of relevant, easy-to-understand education about VLUs may increase physical activity levels, which may facilitate improved time to healing of VLUs.

Effects and associations of nutrition in patients with venous leg ulcers: A systematic review.

AIMS: To identify the associations and effects of nutritional characteristics and interventions on ulcer outcomes in adult patients with venous leg ulcers. BACKGROUND: Venous leg ulcers are the most prevalent type of lower limb ulcer; however, little evidence exists regarding the relationship between nutritional status and ulcer healing. DESIGN: A systematic search of English language articles was conducted using the Cochrane Collaboration Handbook for Systematic Reviews of Interventions. DATA SOURCES: A search of databases Ovid MEDLINE, EMBASE, Cochrane, CINAHL and Scopus was performed for studies published between January 2004 - May 2017. REVIEW METHODS: Quality of the included studies was assessed using the Cochrane Collaboration's Risk of Bias Assessment tool and the relevant Joanna Briggs Institute quality appraisal checklists. RESULTS: Twenty studies met the inclusion criteria. All participants had Clinical Aetiology Anatomy Pathophysiology classification C5 (healed) or C6 (active) ulcers. Studies were conducted in a range of clinical settings with relatively small sample sizes. The majority of patients were overweight or obese. Increased body mass index was associated with delayed wound healing. Vitamin D, folic acid and flavonoids were associated with some beneficial effects on ulcer healing. Dietary intakes of omega-3 fatty acids, vitamin C and zinc were low for some patients. CONCLUSION: Current evidence suggests that venous leg ulcer patients are more likely to be overweight or obese. However, evidence for weight management improving wound healing is lacking. Micronutrients, including vitamin D and folic acid, may improve wound healing in at-risk patients.
