Attitudes and adherence to changes in nutrition and physical activity following surgery for prostate cancer:a qualitative study

OBJECTIVES: Interventions designed to improve men’s diet and physical activity (PA) have been recommended as methods of cancer prevention. However, little is known about specific factors that support men’s adherence to these health behaviour changes, which could inform theory-led diet and PA interventions. We aimed to explore these factors in men following prostatectomy for prostate cancer (PCa). DESIGN, SETTING AND PARTICIPANTS: A qualitative study using semistructured interviews with men, who made changes to their diet and/or PA as part of a factorial randomised controlled trial conducted at a single hospital in South West England. Participants were 17 men aged 66 years, diagnosed with localised PCa and underwent prostatectomy. Interview transcripts underwent thematic analysis. RESULTS: Men were ambivalent about the relationship of nutrition and PA with PCa risk. They believed their diet and level of PA were reasonable before being randomised to their interventions. Men identified several barriers and facilitators to performing these new behaviours. Barriers included tolerance to dietary changes, PA limitations and external obstacles. Facilitators included partner involvement in diet, habit formation and brisk walking as an individual activity. Men discussed positive effects associated with brisk walking, such as feeling healthier, but not with nutrition interventions. CONCLUSIONS: The facilitators to behaviour change suggest that adherence to trial interventions can be supported using well-established behaviour change models. Future studies may benefit from theory-based interventions to support adherence to diet and PA behaviour changes in men diagnosed with PCa

Tobacco and alcohol cessation or reduction interventions in people with oral dysplasia and head and neck cancer:systematic review protocol

Abstract Background Head and neck cancers include malignancies of the mouth, larynx and oropharynx. Tobacco use and alcohol consumption are associated with increased risks of developing and dying from head and neck cancer. The aim of this review is to examine the effectiveness of smoking and alcohol cessation interventions on disease-related outcomes, quality of life and behavioural change in adults with head and neck cancer and oral dysplasia. Methods The Cochrane library, CINAHL, Embase, MEDLINE, PsycINFO and Web of Science databases will be searched for randomised controlled trials investigating the effects of smoking or alcohol interventions on patients with either head and neck cancer or oral dysplasia. The primary outcomes are disease-free survival and, for participants with oral dysplasia, malignant transformation to cancer. Secondary outcomes are disease recurrence and progression, quality of life and behavioural change. The quality of included studies will be assessed using the ‘Cochrane Collaborations tool for assessing risk of bias’. A qualitative synthesis of the results will be reported, and a meta-analysis of the outcome data conducted, where appropriate. Discussion This systematic review will identify the extent of the current research on smoking and alcohol cessation interventions in patients with head and neck cancer and oral epithelial dysplasia. The findings have the potential to inform which interventions have been successful and how future behavioural change interventions should be conducted within these populations.
