Nutrition and Exercise Knowledge, Attitude, and Practice: A Scoping Review of Assessment Questionnaires in Cancer Survivorship.

Cancer survivors are encouraged to maintain a healthy diet and engage in regular exercise to improve overall physical and psychosocial health, and to reduce the likelihood of cancer recurrence and related mortality. Consequently, nutrition and exercise (the structured component of physical activity) knowledge, attitude, and practice (NE-KAP) are frequently evaluated in research studies involving cancer survivors and are associated with various health outcomes. The aims of this scoping review were to (1) systematically map the types of NE-KAP assessment questionnaires used in cancer survivorship research (i.e., trend or use over the past five years), (2) provide a directory of questionnaires, and (3) identify the most frequently reported health outcomes that have been associated with them. A systematic search was conducted across four databases-Medline, Emcare, CINAHL, and Scopus-from 1 January 2019 to 9 May 2024, for studies addressing one or more aspects of NE-KAP (e.g., food frequency questionnaire for nutrition practice, attitude towards exercise scale for exercise attitude). Eligible studies were extracted, assessed, and reviewed by two independent authors, and data were summarized descriptively. Of the initial 5452 records screened, 1122 articles were screened for full text, and 852 were deemed eligible, with 262 studies included. There was an overall increasing trend in NE-KAP research in cancer survivorship research from 2019 to 2023. Of the 200 unique questionnaires aligning with at least one NE-KAP domain, 45 were untitled and created/adapted specifically for their respective studies, with limited information about their psychometric properties. Out of the 262 included studies, the most utilized questionnaires were those measuring nutrition or physical activity practices, such as study-specific food frequency questionnaires ( = 26, 10%) and the Godin-Shephard Leisure-Time Physical Activity questionnaire ( = 52, 20%). Out of studies that had reported health outcomes (nutrition, = 23; exercise, = 40), health-related quality of life was most commonly associated with nutrition ( = 12, 53%) and exercise ( = 9, 23%), and from cross-sectional studies (nutrition, = 13; exercise, = 23). An emphasis was placed on assessing nutrition and exercise practices, with limited attention towards the knowledge and attitude domains. Psychometric evaluation of questionnaires was also lacking.
