Still, other factors, such as diet composition, have not been considered. This study aims to determine the association between serum UA, impulsivity\/hyperactivity symptoms, and dietary components in adults with psychiatric disorders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec002\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A prospective cross-sectional study was conducted on 128 adults who attended a psychiatric service. Fasting serum UA levels were determined by spectrophotometry. Impulsivity and hyperactivity symptoms were evaluated using the Adult ADHD Self-Report Scale (ASRS). Dietary components, including macronutrients, fiber, fructose, added sugar, vitamin C, zinc, copper, n-3 fatty acids, caffeine, and alcohol, were estimated using a 24-hour recall, food models, and nutrition software. Spearman's correlation and general linear models were applied. The last was used to adjust for confounders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Serum UA levels were positively correlated to symptoms of hyperactivity\/impulsivity and hyperactivity (\n                      <jats:italic>Rho<\/jats:italic>\n                      \u2009=\u20090.206,\n                      <jats:italic>p<\/jats:italic>\n                      =\u20090.020;\n                      <jats:italic>Rho<\/jats:italic>\n                      \u2009=\u20090.194,\n                      <jats:italic>p<\/jats:italic>\n                      =\u20090.028, respectively).
