DataSheet_1_Sirtuin 1 serum concentration in healthy children - dependence on sex, age, stage of puberty, body weight and diet.docx

IntroductionSirtuin 1 (SIRT1) is known to be involved in sensing cellular energy levels and regulating energy metabolism. This study aimed to evaluate fasting serum SIRT1 levels in healthy children, and to analyse the influence of age, sex, puberty, body weight, height, and diet on its concentration.
Methods47 healthy children aged 4-14 with weight and height within normal range and no chronic disease were included into the study. Fasting serum SIRT1 concentrations were estimated by Enzyme Linked Immunosorbent Assay (ELISA).
ResultsResults showed that serum SIRT1 concentrations in healthy children did not differ with respect to sex, age, height, weight and puberty. Whereas, it appeared that a higher frequency of fruits, vegetables and dairy products consumption was associated with an increase in serum SIRT1 levels.
DiscussionStudying SIRT1 in the context of children’s health may have implications for a broader understanding of growth processes, pubertal development, metabolic disorders and nutrition.
