The association between interest of nutritional supplements and COVID-19 pandemic - evidence from Google Trends.

BACKGROUND: Due to the spread of the coronavirus disease 2019 (COVID-19) pandemic in 2020, the interest of nutritional supplements has emerged. Limited data are available on how the COVID-19 pandemic affects the search interest in nutritional supplements in Taiwan and worldwide. The study aims to investigate changes in public search interest of nutritional supplements pre- and during the COVID-19 pandemic. METHODS: Our World in Data dataset was used to collect both global and local (Taiwan) number of COVID-19 newly confirmed cases and deaths. Google Trends search query was being used to obtain relative search volumes (RSVs) covering a timeframe between 2019 to 2022. Spearman's rank-order correlation coefficients were used to measure relationships between confirmed new cases and deaths and RSVs of nutritional supplements. Multivariate analysis was conducted to examine the effect of domestic and global new cases and deaths on the RSVs of nutritional supplements. RESULTS: The mean RSVs for nutritional supplements were higher during the COVID-19 pandemic period (between 2020 to 2022) compared to the pre-pandemic period (year of 2019) for both Taiwan and worldwide. In terms of seasonal variations, except for vitamin D, the mean RSVs of probiotics, vitamin B complex, and vitamin C in winter were significantly lower compared to other seasons in Taiwan. The RSVs of nutritional supplements were not only affected by domestic cases and deaths but also by global new cases and deaths. CONCLUSIONS: The interests in nutritional supplements had substantially increased in response to the COVID-19 pandemic. The RSVs of nutritional supplements in Taiwan were not only influenced by global and domestic pandemic severity but also by seasons.

Developing an International Classification of Functioning, Disability and Health Core Set for Pediatric Brain Tumor Survivors in Chinese Clinical Settings.

BACKGROUND: The International Classification of Functioning, Disability and Health (ICF) core set (CS) facilitates the standardization of functioning and impairment assessment for integration of holistic care. OBJECTIVE: This study developed an ICF CS for interviewing pediatric brain tumor survivors in Taiwan to help healthcare professionals in implementing disability assessment and management measures. METHODS: A group of 29 experts in 10 relevant fields with at least 5 years of experience working with children with brain tumors participated in this study. The first questionnaire contained 247 second-level ICF categories. The experts rated the significance of each category by using a 5-point Likert scale. Correlations between individual and group scores were calculated to determine consensus. Categories with an average rating of higher than 4 and for which greater than or equal to 80% (23) of the participants provided a rating of 4 or higher were included in the final CS. RESULTS: The final CS contained a total of 57 ICF categories: 20 from the Body Functions and Structures component, 36 from the Activities and Participation component, and 1 from the Environmental Factors component. CONCLUSION: The ICF CS for pediatric brain tumor survivors provides a framework for relevant healthcare professionals to deliver patient-centered care, ensuring that services focus on all areas of development. IMPLICATIONS FOR PRACTICE: Patient ratings for this ICF CS may serve as a new practical and effective patient-reported information tool for acquiring patient input and for the systematic monitoring of pediatric brain tumor survivors in clinical practice. Further research should be conducted on this CS to verify our findings.
