Perceived influences on post-diagnostic dietary change among a group of men with prostate cancer

A Better Me? An Interpretative Phenomenological Analysis of the Experiences of Female Cancer Survivors' Heightened Preoccupation With 'Healthy Eating'

The end of treatment is known to be a particularly challenging time for many cancer survivors as they transition to coping with their condition independently. They may engage in health behaviours, such as implementing drastic dietary changes to manage the side effects of treatment they have undergone or as a way to assuage their anxiety. Understanding cancer survivors' heightened preoccupation with healthy eating is therefore fundamental to our understanding of the psychological phenomenology of cancer. This study explored how people who have developed a heightened preoccupation with healthy eating after a cancer diagnosis make sense of this change. Eight participants were recruited through social media. They each engaged in a semi-structured interview over Zoom concerning their changed relationship with food following cancer. Their accounts were then analysed using interpretative phenomenological analysis (IPA). The article focuses on four group experiential themes arising from the analysis: Open and Enlightened About Food, Becoming a Better Me?, Developing a New Passion for Nutrition, and Becoming Consumed by Food. The themes that arose from the analysis speak to the experience of becoming a 'better' person from having lived through cancer and developed a new relationship with food. Instead of seeing illness as a loss, several of the participants reported a positive shift linked to having developed an interest in healthy eating, something which became central to their identity. However, others experienced their new engagement with healthy eating as a preoccupation that engulfed them. These findings are discussed in light of existing theory and research, and their clinical implications are outlined. Areas for future research are also suggested.

Stone diet and dietary change: understanding determinants for dietary change behaviour in patients following urinary stones

BACKGROUND

Dietary habit is one of the most important methods to prevent and treat urinary stones. However, only limited evidence of the experiences of dietary management among urinary stone patients in Malaysia is available. This study aimed to explore participants' current dietary practices after the diagnosis of urinary stones and to identify the factors that facilitate their dietary changes.

METHODS

A qualitative study with purposive sampling was conducted using face-to-face semistructured interviews. A total of 20 participants from a tertiary general hospital in Kuantan, Malaysia, were recruited in this study. Data were analysed using framework analysis.

RESULTS

Two themes emerged from the analysis. The first theme explained the changes in the dietary practice of the participants postdiagnosis. The second theme revealed that the participants' dietary changes were greatly influenced by personal factors and external support from professionals, family and peers.

CONCLUSIONS

Urinary stone patients highlighted the fear of complications, self-determination and knowledge of nutrition as the main drivers of their dietary change postdiagnosis. Emphasising proper nutritional care by assessing and evaluating dietary self-management among patients can facilitate effective self-care in stone prevention management.

"Keep Your Chin Up, and Keep Eating": Perceptions of Barriers and Facilitators to Healthful Dietary Behaviors Among Individuals With Gastrointestinal Cancer and Caregivers

BACKGROUND

This study explored perceptions of barriers and facilitators to healthful dietary behaviors among patients with gastrointestinal (GI) cancer and their caregivers, including caregiver preparedness, patient and caregiver self-efficacy for symptom management, and other environmental, social, and familial factors that may serve as barriers and facilitators to healthful eating.

METHODS

Using a concurrent mixed methods cross-sectional study design, individuals with GI cancer receiving outpatient chemotherapy and their caregivers completed surveys, dietary assessments, and interviews. Caregiving preparedness, self-efficacy for symptom management, and dietary intake were assessed using validated instruments. Dietary quality was measured using the Healthy Eating Index (HEI)-2020. In-depth interviews explored barriers and facilitators to healthful eating, symptom management, and caregiver preparedness.

RESULTS

Twenty-seven patient-caregiver dyads completed study activities (N = 54). Dietary quality scores ranged from 26 to 81, with a median score of 43 for patients and 42 for caregivers. Thematic analysis identified three barriers to healthful eating: caregiver self-efficacy and preparedness, caregiver needs are neglected, and nutrition as a source of conflict. Overall self-efficacy scores (Mdn, [IQR]) were 69.1 (45.0) for caregivers and 75.6 (34.1) for patients. Caregiver preparedness score was 2.99 ± .87; problem areas were identified, including addressing emotional needs, fluctuating eating habits, advanced disease progression and making care activities pleasant. Despite the challenges, three main facilitators were identified: increased awareness and value of nutrition, influential others, and positive coping.

CONCLUSION

Our findings suggest the importance of developing interventions that increase nutrition-related preparedness among caregivers and self-efficacy for managing treatment side effects. Future research should continue to explore the relationship between positive coping and dietary behaviors. While engaging patients and caregivers together during dietary interventions is a promising modality, strategies for maintaining personal nutrition-related goals when facing contrasting priorities between patients and caregivers should be addressed.

Psychosocial Determinants of Lifestyle Change after a Cancer Diagnosis: A Systematic Review of the Literature

Simple Summary

Although cancer survivors may experience health benefits from favorable lifestyle changes, many cancer survivors do not adhere to lifestyle recommendations or make favorable lifestyle changes after cancer diagnosis. This systematic review of the literature aimed to provide an overview of the scientific literature on sociodemographic, psychological and social determinants that may facilitate or hamper lifestyle change after the diagnosis cancer. It provides a structured overview of the large variety of determinants of changes in different lifestyle behaviors (physical activity, diet, smoking, alcohol, sun protection, and multiple lifestyle behaviors) derived from the 123 included papers (71 quantitative and 52 qualitative). Findings demonstrate the important role of oncology healthcare professionals in promoting healthy lifestyle changes in cancer survivors and inform researchers and healthcare professionals about the methods and strategies they can use to promote healthy lifestyle changes in cancer survivors.

Abstract

The aim of this study is to provide a systematic overview of the scientific literature on sociodemographic, psychological and social determinants that may facilitate or hamper lifestyle change after the diagnosis cancer. Four databases (PubMed, PsychINFO, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science) were searched for relevant papers up to October 2021. Of the 9586 references yielded by the literature search, 123 papers were included: 71 quantitative and 52 qualitative papers. Findings showed a large variety of determinants influencing lifestyle change after cancer diagnosis, with differences between lifestyle behaviors (physical activity, diet, smoking, alcohol, sun protection, and multiple lifestyle behaviors) and findings from quantitative vs. qualitative studies. Findings demonstrate the important role of oncology healthcare professionals in promoting healthy lifestyle changes in cancer survivors. In addition, findings inform researchers involved in the development of health promotion programs about the methods and strategies they can use to promote healthy lifestyle changes in cancer survivors. Favorable lifestyle changes are expected to have beneficial effects on cancer risk and overall health in cancer survivors.

Supportive care needs of men with prostate cancer: A systematic review update

BACKGROUND

Prostate cancer is highly prevalent and impacts profoundly on patients' quality of life, leading to a range of supportive care needs.

METHODS

An updated systematic review and thematic synthesis of qualitative data using the Preferred Reporting Items for Systematic Reviews (PRISMA) reporting guidelines, to explore prostate cancer patients' experience of, and need for, supportive care. Five databases (Medline, Embase, PsycInfo, Emcare and ASSIA) were searched; extracted data were synthesised using Corbin and Strauss's 'Three Lines of Work' framework.

RESULTS

Searches identified 2091 citations, of which 105 were included. Overarching themes emerged under the headings of illness, everyday life and biographical work. Illness work needs include consistency and continuity of information, tailored to ethnicity, age and sexual orientation. Biographical work focused on a desire to preserve identity in the context of damaging sexual side effects. Everyday life needs centred around exercise and diet support and supportive relationships with partners and peers. Work-related issues were highlighted specifically by younger patients, whereas gay and bisexual men emphasised a lack of specialised support.

CONCLUSION

While demonstrating some overarching needs common to most patients with prostate cancer, this review offers novel insight into the unique experiences and needs of men of different demographic backgrounds, which will enable clinicians to deliver individually tailored supportive care.

Diet and Nutrition Advice After a Solid Tumor Diagnosis

PURPOSE

Credible evidence-based diet and nutrition advice is essential for patients with cancer. This study aimed to explore what advice patients with cancer obtained before a formal dietetic visit.

METHODS

A multicenter, observational study was conducted in seven hospital-based oncology services. Consecutive patients were recruited at first dietetic assessment. In addition to routine dietetic assessment, participants completed a four-item questionnaire describing diet and nutrition advice obtained since diagnosis.

RESULTS

Seventy-seven patients participated. More than 80% had multiple nutrition-impact symptoms. In total, 53 (69%) obtained advice from professional and nonprofessional sources before dietetic visit. Family and friends were the most common sources of advice. More than one third got advice from (nondietetic) healthcare professionals. Most advice related to "foods to include" (61%) and "foods to avoid" (54%) in the diet. Many of the "foods to avoid" were important sources of micro- and macronutrients. Advice about dietary supplements (31%) and specific diets (28%) was common, rarely evidence-based, and frequently contradictory. Participants found it difficult to discern what advice was trustworthy and reliable. Despite this, most followed the advice.

CONCLUSION

The majority of patients received diet and nutrition advice before first dietetic visit. Most of this came from nonprofessional sources. Any advice from nondietetic healthcare professionals was inconsistent or vague. This was mainly related to the avoidance and/or inclusion of particular foods and was often contradictory. Nevertheless, patients usually followed such advice fully. To help manage their frequent nutrition-impact symptoms and resolve the contradictory advice they had received, many expressed the need for earlier professional dietetic consultation.

The provision of nutritional advice and care for cancer patients: a UK national survey of healthcare professionals

Purpose

People living with and beyond cancer often experience nutrition-related issues and should receive appropriate advice on nutrition that is consistent and evidence based. The aim of this study was to investigate current practice for the provision of nutritional care by healthcare professionals (HCPs) from a UK national survey produced by the National Institute for Health Research (NIHR) Cancer and Nutrition Collaboration.

Methods

An online survey sent to professional groups and networks included questions on discussing nutrition, providing information, awareness of guidelines, confidence in providing nutritional advice, training and strategies for improving nutritional management.

Results

There were 610 HCPs who responded including nurses (31%), dietitians (25%), doctors (31%) and speech and language therapists (9%). The majority of HCPs discusses nutrition (94%) and provides information on nutrition (77%). However, only 39% of HCPs reported being aware of nutritional guidelines, and just 20% were completely confident in providing nutritional advice. Awareness of guidelines varied between the different professional groups with most but not all dietitians reporting the greatest awareness of guidelines and GPs the least (p = 0.001). Those HCPs with a greater awareness of guidelines had received training (p = 0.001) and were more likely to report complete confidence in providing nutritional advice (p = 0.001).

Conclusion

Whilst HCPs discuss nutrition with cancer patients and may provide information, many lack an awareness of guidelines and confidence in providing nutritional advice. To ensure consistency of practice and improvements in patient care, there is scope for enhancing the provision of appropriate nutrition education and training.

Diet and nutrition information and support needs in pelvic radiotherapy: A systematic, mixed-methods review

INTRODUCTION

This study aimed to review diet and nutrition information and support needs of cancer patients who receive pelvic radiotherapy to inform the development of interventions to improve this area of care.

METHODS

The systematic review followed the PRISMA guidelines. Six electronic databases were searched for peer-reviewed studies of any design that assessed diet and nutrition needs after a pelvic cancer diagnosis. Narrative synthesis was used to integrate findings.

RESULTS

Thirty studies (12 quantitative, 15 qualitative, 3 mixed-methods) were included. Four themes, "content of dietary information"; "sources of information"; "sustaining dietary change"; and "views on the role of diet post-treatment," summarised evidence about provision of nutritional guidance following diagnosis, but also contrasting views about the role of diet post-diagnosis. Qualitative studies contributed considerably more to the synthesis, compared to quantitative studies. Included studies were of moderate to good quality; selection bias in quantitative studies and poor evidence of credibility and dependability in qualitative studies were highlighted.

CONCLUSION

There is some evidence of lack of nutrition support in pelvic cancer survivors, but methodological limitations of included studies may have had an impact on the findings. Future, prospective studies that focus on diet and nutrition needs post-diagnosis are warranted to improve care.

Diet and weight management by people with nonmetastatic colorectal cancer during chemotherapy: mixed methods research

Aim: To investigate self-management of dietary intake by colorectal cancer patients receiving chemotherapy. Methods: A questionnaire was administered to 92 patients with nonmetastatic colorectal cancer receiving chemotherapy treatment at a UK cancer center in 2018–19. A maximum variation sample of 20 patients who completed the questionnaire were interviewed. Results: More than three in five patients were at nutritional risk but fewer than one in five were concerned about dietary intake or weight. Self-management of diet and weight was inconsistent with achieving the nutritional intake recommended by clinical guidelines on nutrition in cancer. Conclusion: There is potential for psychoeducation to support change in self-management of nutritional risk, with implications for better treatment tolerance and outcomes including quality of life.

Stable, fragile and recreated - a qualitative study of agency in everyday life with breast and prostate cancer

Purpose: This study aims to explore how agency is constructed in everyday life with cancer in relation to daily activities and habits. Agency is approached as a key element of daily life existence, and it is constructed in terms of "acting in the world", self-behaviour, changing routines, identity expectations and life course.Methods: The study is based on a social constructionist approach and the data of 32 participants were gathered through a public call for narratives on "everyday life with breast and prostate cancer" in Finland in 2009. The analysis was conducted by utilizing a discursive research approach and coding.Results: Three categories of agency were identified: stable-where agency continues fluently after cancer; fragile-where the ability to take care of daily activities has deteriorated; and recreated-where living with cancer adapts or creates a new basis for daily living.Conclusions: The findings of the study suggest that everyday life activities and habits define and (de)construct agency, and that these constructions are tightly linked to the ill person's overall life situation, physical abilities and cultural context. Having cancer can create new challenges to agency in daily life but does not suppress agency.

Facilitators and barriers to participation in lifestyle modification for men with prostate cancer: A scoping review

PURPOSE

Diet and physical activity changes have been shown to improve quality of life and health outcomes for prostate cancer (PC) survivors; however, few survivors make lifestyle changes. We aimed to identify PC-specific facilitators and barriers to dietary and physical activity changes and participation in survivorship-based lifestyle management programmes.

METHODS

A scoping review investigating facilitators and barriers of PC survivor's participation in lifestyle management programmes was conducted in June 2018. A total of 454 studies were identified, 45 studies were assessed in full, and 16 were included in the scoping review.

RESULTS

Barriers to lifestyle change included perceived lack of evidence for lifestyle guidelines, treatment side effects, perception of change as unnecessary, time pressure and age. Facilitators for lifestyle change included advice from health professionals, support systems (family and peer), diagnosis as a time for change, lifestyle as a coping strategy to manage side effects and improve well-being.

CONCLUSIONS

Health professionals, peers and family have a significant role in lifestyle management for PC survivors to facilitate engagement. Specific and clear messaging of the benefits of lifestyle management is warranted. Treatment-related side effects, time pressure, current health perception and age should be considered when developing lifestyle management programmes for PC survivors.

Making Active Surveillance a path towards health promotion: A qualitative study on prostate cancer patients' perceptions of health promotion during Active Surveillance

OBJECTIVE

Health promotion is a key aspect for health outcomes of prostate cancer (PCa) patients. However, it has been poorly explored among patients following monitoring programmes, for example Active Surveillance (AS). This study aimed to explore PCa patients' perceptions of health promotion during AS.

METHODS

An explorative qualitative research design was adopted. Four focus groups were used to collected data from 24 men enrolled in the Prostate Cancer Research International: AS (PRIAS) protocol. A thematic analysis with an inductive approach was performed.

RESULTS

Participants described promoting health during AS as challenged by mental, age-related, informational and organisational issues. It was reported as an effort to stay in the present with a positive outlook, despite the worries for the future ("the mental theme"). It was perceived as impacted by being older and having to manage physical and mental struggles related to age ("the life-course theme"). It depended, in their accounts, on obtaining reliable information and personalised education ("the educational theme"). Finally, it was related on taking responsibility on the care process ("the organisational theme").

CONCLUSION

This study suggested ways of promoting health during AS that can help healthcare professionals and organisations building a "health-promoting AS," able to improve overall health outcomes.

The feasibility of the Prostate cancer: Evidence of Exercise and Nutrition Trial (PrEvENT) dietary and physical activity modifications: a qualitative study

Background

There is increasing evidence that low levels of physical activity and diets low in fruit and vegetables and high in meat and dairy products are risk factors for prostate cancer disease progression. The Prostate cancer: Evidence of Exercise and Nutrition Trial (PrEvENT) aimed to assess a diet and physical activity intervention in men undergoing radical prostatectomy for localized prostate cancer. The trial included a qualitative component to explore the experiences of men participating in the trial in order to understand the acceptability of the intervention and data collection methods. We report the qualitative findings of the trial and consider how these can be used to inform future research.

Methods

PrEvENT involved randomizing men to either a dietary and/or physical activity intervention. Semi-structured interviews were conducted with a purposive sample of 17 men on completion of the 6 month trial. Interviews took place in clinic or as telephone interviews, if requested by the participant, and were audio recorded, transcribed, and analyzed using the thematic-based framework approach. Analysis was conducted throughout the data collection process to allow emergent themes to be further explored in subsequent interviews.

Results

Three overarching themes were identified: acceptability of the intervention, acceptability of the data collection methods and trial logistics. Participants were predominantly positive about both the dietary and physical activity interventions and most men found the methods of data collection appropriate. Recommendations for future trials include consideration of alternative physical activity options, such as cycling or gym sessions, increased information on portion sizes, the potential importance of including wives or partners in the dietary change process and the possibility of using the pedometer or other wearable technology as part of the physical activity intervention.

Conclusions

We provide insight into the opinions and experiences of the acceptability of the PrEvENT diet and physical activity intervention from the participants themselves. The interventions delivered were acceptable to this sample of participants, as were the data collection methods utilized. We also highlight some considerations for further behavioural change interventions in prostate cancer and other similar populations.

Risk Factors for Chronic Diseases and Multimorbidity in a Primary Care Context of Central Argentina: A Web-Based Interactive and Cross-Sectional Study

Global health agencies estimate an increase of chronic diseases in South America. Nevertheless, few studies have investigated chronic diseases and their risk factors in the perspective of multimorbidity. This research aimed to identify these aspects in a primary health care setting of central Argentina. The Pan America version of the STEP wise approach surveillance (STEPS) instrument of the World Health Organization was applied to 1044 participants, 365 men and 679 women, with a mean age of 43 years. High prevalence of overweight (33.5%), obesity (35.2%), central obesity (54%), dyslipidemia (43.5%), metabolic syndrome (21.1%), low intake of fruit and vegetables (91.8%), low levels of physical activity (71.5%), risky alcohol consumption (28%), and smoking (22.5%) were detected. Hypertension and diabetes were the most prevalent chronic conditions and the total prevalence of multimorbidity was 33.1%, with 2, 3, 4, 5 and 6 chronic conditions found in 19.9%, 9.1%, 2.6%, 1.1% and 0.4% of the population, respectively. Multimorbidity affected 6.4% of the young, 31.7% of the adults, and 60.6% of the elderly, and was more prevalent among women, and in participants with lower levels of education. Having multimorbidity was significantly associated with obesity, central obesity, and higher concentrations of total blood cholesterol, low-density lipoprotein cholesterol, triglycerides, and glucose. A website was made available to the participants in order to share the experimental results and health-promoting information.

"What about diet?" A qualitative study of cancer survivors' views on diet and cancer and their sources of information

Given the abundance of misreporting about diet and cancer in the media and online, cancer survivors are at risk of misinformation. The aim of this study was to explore cancer survivors' beliefs about diet quality and cancer, the impact on their behaviour and sources of information. Semi-structured interviews were conducted with adult cancer survivors in the United Kingdom who had been diagnosed with any cancer in adulthood and were not currently receiving treatment (n = 19). Interviews were analysed using Thematic Analysis. Emergent themes highlighted that participants were aware of diet affecting risk for the development of cancer, but were less clear about its role in recurrence. Nonetheless, their cancer diagnosis appeared to be a prompt for dietary change; predominantly to promote general health. Changes were generally consistent with healthy eating recommendations, although dietary supplements and other non-evidence-based actions were mentioned. Participants reported that they had not generally received professional advice about diet and were keen to know more, but were often unsure about information from other sources. The views of our participants suggest cancer survivors would welcome guidance from health professionals. Advice that provides clear recommendations, and which emphasises the benefits of healthy eating for overall well-being, may be particularly well-received.

Food Habits, Lifestyle Factors, and Risk of Prostate Cancer in Central Argentina: A Case Control Study Involving Self-Motivated Health Behavior Modifications after Diagnosis

Cancer is the second most important non-communicable disease worldwide and disproportionately impacts low- to middle-income countries. Diet in combination with other lifestyle habits seems to modify the risk for some cancers but little is known about South Americans. Food habits of Argentinean men pre- and post-diagnosis of prostate cancer (n = 326) were assessed along with other lifestyle factors. We studied whether any of the behaviors and risk factors for prostate cancer were found in men with other cancers (n = 394), compared with control subjects (n = 629). Before diagnosis, both cases reported a greater mean consumption of meats and fats and lower intakes of fruits, green vegetables, cruciferous vegetables, legumes, nuts, seeds, and whole grains than the controls (all p < 0.001). After diagnosis, cases significantly reduced the intake of meats and fats, and reported other dietary modifications with increased consumption of fish, fruits (including red fruits in prostate cancer), cruciferous vegetables, legumes, nuts, and black tea (all p < 0.001). Additional lifestyle aspects significantly predominant in cases included a reduced quality of sleep, emotional stress, low physical activity, tobacco smoking, alcohol consumption, living in rural areas, and being exposed to environmental contaminants. Argentinian men were predisposed to modify their unhealthy dietary habits and other lifestyle factors after cancer diagnosis.
