Introduction High serum uric acid due to improper dietary intake has been identified to associate with painful gouty attack. This study investigates the relationship between point-of-care testing in uric acid and the dietary pattern among participants attending the 2014 Vegetarian Festival in Hong Kong.
Method A cross-sectional study was conducted using questionnaire to collect demographic data and dietary pattern of the participants. Point-of-care analyzer was used to measure their serum uric acid. Data was analyzed by descriptive and non-parametric statistics.
Results A total of 94 health seekers participated in the study. A prevalence of high POC-UAs was identified among these participants (14.9% (14/94)); non-vegetarians (18.5% (12/65)) tended to have a higher proportion of high POC-UAs compared to vegetarians (7.1% (2/28)); half of these participants with high POC-UAs had obesity 23.5% (4/17) and 1-3 chronic diseases (53.3% (8/15)). The POC-UAs of those having 1-3 chronic diseases 53.3% (8/15) were also significantly greater than those of a single chronic disease 25.0% (1/4) (Χ²=26.769, p<0.001).
Discussion The findings suggested that Point-of-care testing can be an effective predictor of gout risk as most individuals may be unaware of their hyperuricemia condition because of asymptomatic at an early stage.
Conclusion For a better control of hyperuricemia and prevention of acute gouty attack, health education with a convenient monitoring using Point-of-care method and dietary intervention is recommended.
