RESUMO
This review aimed to map current evidence on the association between dietary factors and colorectal cancer (CRC) risk in Asia. This review was conducted based on Arksey and O'Malley methodological framework. Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) flow diagram was used to record the review process. For the purpose of searching for articles, three electronic databases namely PubMed, EBSCOHost and ScienceDirect were employed. The inclusion criteria for articles selection were articles with association analysis between diet and CRC risk among Asians, had adults as participants, articles were written in English, open-accessed and published between years 2009 and 2021. Thus, 35 out of 369 screened articles were eventually included in this review which covered 28 case-control studies, six prospective cohort studies and one randomised clinical trial. Foods such as meats, alcohol and westernised diet have been shown to be associated with increase of CRC risk while fruits, vegetables and traditional meals decreased the risk of CRC. Only a few interventional and dietary patterns studies were identified. Specific single foods and nutrients and dietary patterns have been found to increase the risk but also protected the Asian population against CRC. The findings of this review will guide health professionals, researchers and policy makers to conduct a suitable study design and topic for future research.
RESUMO
BACKGROUND: University students generally tend to engage in problematic eating behaviours, including unhealthy dieting, skipping meals, and high intake of fast food, although they are aware of the negative consequences. Eating behaviours have been shown to be interestingly related to quality of life (QoL). Our study aimed to 1) assess general nutrition quality of life (NQoL) status and 2) compare NQoL status based on gender, financial resources, study courses, year of study, and body mass index (BMI) profiles. METHODS: This study was conducted among undergraduates of health sciences in a local public university in Terengganu. Students completed the Malay version of NQoL (6 domains; 50 items; Likert-type responses 1-5). Data analysis was carried out by using SPSS 16.0, utilising descriptive and parametric statistics. RESULTS: A total of 241 students were enrolled [age = 19.7 (0.1) years; female (83.0%); Malay (96.7%)]. Social/Interpersonal Factors [3.84 (0.43)] emerged as the best component, while Food Impact [3.10 (0.40)] was the worst. Across all variables, only gender and study courses showed significantly different NQoL. Females scored better than males in Self-Efficacy (confidence in food selection ability) (P < 0.05). Nursing students also experienced significantly greater NQoL (mean = 3.58, 95% CI = 3.47, 3.68) than radiography students in Self-Efficacy (p < 0.05). Medical laboratory technology students had a significantly more favourable NQoL rating (mean = 3.62, 95% CI = 3.47, 3.76) than nursing students in Self-Image (p < 0.05). Study courses significantly influenced the NQoL status of students with Good NQoL, while those with Poor NQoL were mostly influenced by gender and financial resources (p < 0.05). CONCLUSION: These outcomes indicate that specific demographic characteristics seemed to make a difference in the NQoL of undergraduate students.
