Recent studies have measured UA in saliva in relation to obesity and chronic disease risk. Given the increasing prevalence of metabolic syndrome among Latino youth, we examined gender and age differences in salivary uric acid (sUA) and weight in a sample of Mexican\u2010origin children (<jats:italic>n<\/jats:italic>\u2009=\u200965, 2 months to 18 years, 49% female) and adults (<jats:italic>n<\/jats:italic>\u2009=\u200946, 19\u201358 years, 72% female). We measured weight, height, waist, and hip circumference and collected saliva samples (later assayed for sUA). Structural equation models estimated the relationship between age, developmental stage, and weight outcomes in relation to sUA levels between genders, while controlling for race. Results demonstrate that increased sUA levels were related to higher BMI percentiles in females of all ages (<jats:italic>\u03b2<\/jats:italic>\u2009=\u20090.43,<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001). There were significant differences in sUA levels between developmental stages for girls, with female toddlers having the highest sUA levels (<jats:italic>\u03b2<\/jats:italic>\u2009=\u2009.28,<jats:italic>p<\/jats:italic>\u2009=\u2009.02). In an interaction between BMI<jats:italic>z<\/jats:italic>\u2010score and gender between youth and adults, BMI has a larger effect on increasing sUA levels among younger girls (<jats:italic>\u03b2<\/jats:italic>\u2009=\u20090.27,<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.03) and adult women (<jats:italic>\u03b2<\/jats:italic>\u2009=\u20090.33,<jats:italic>p<\/jats:italic>\u2009=\u2009.02).
