The aim of this study was to evaluate the insulin resistance (IR) using the HOMA (<jats:italic>Homeostasis Model Assessment<\/jats:italic>) method, in DS adolescents, describing it according to the sex, body mass index (BMI) and pubertal development.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>15 adolescents with DS (8 males and 7 females) were studied, aged 10 to 18 years, without history of disease or use of medication that could change the suggested laboratory evaluation. On physical examination, the pubertal signs, <jats:italic>acanthosis nigricans (AN)<\/jats:italic>, weight and height were evaluated. Fasting plasma glucose and insulin were analysed by the colorimetric method and RIA-kit LINCO, respectively. IR was calculated using the HOMA method. The patients were grouped into obese, overweight and normal, according to their BMI percentiles. The EPIINFO 2004 software was used to calculate the BMI, its percentile and Z score.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Five patients were adults (Tanner V or presence of menarche), 9 pubertal (Tanner II \u2013 IV) and 1 prepubertal (Tanner I). No one had <jats:italic>AN<\/jats:italic>. Two were obese, 4 overweight and 9 normal. Considering the total number of patients, HOMA was 1.7 \u00b1 1.0, insulin 9.3 \u00b1 4.8 \u03bcU\/ml and glucose 74.4 \u00b1 14.8 mg\/dl. The HOMA values were 2.0 \u00b1 1.0 in females and 1.5 \u00b1 1.0 in males. Considering the nutritional classification, the values of HOMA and insulin were: HOMA: 3.3 \u00b1 0.6, 2.0 \u00b1 1.1 and 1.3 \u00b1 0.6, and insulin: 18.15 \u00b1 1.6 \u03bcU\/ml, 10.3 \u00b1 3.5 \u03bcU\/ml and 6.8 \u00b1 2.8 \u03bcU\/ml, in the obese, overweight and normal groups respectively. Considering puberty, the values of HOMA and insulin were: HOMA: 2.5 \u00b1 1.3, 1.4 \u00b1 0.6 and 0.8 \u00b1 0.0, and insulin: 13.0 \u00b1 5.8 \u03bcU\/ml, 7.8 \u00b1 2.9 \u03bcU\/ml and 4.0 \u00b1 0.0 \u03bcU\/ml, in the adult, pubertal and prepubertal groups respectively.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>The obese and overweight, female and adult patients showed the highest values of HOMA and insulin.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1472-6823-5-6","type":"journal-article","created":{"date-parts":[[2005,6,17]],"date-time":"2005-06-17T18:14:10Z","timestamp":1119032050000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":46,"title":["Insulin resistance in adolescents with Down syndrome: a cross-sectional study"],"prefix":"10.1186","volume":"5","author":[{"given":"Cristina T","family":"Fonseca","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela M","family":"Amaral","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M\u00e1rcia G","family":"Ribeiro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Izabel CR","family":"Beserra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00edlia M","family":"Guimar\u00e3es","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2005,6,17]]},"reference":[{"key":"19_CR1","first-page":"638","volume-title":"Endocrinologia Pedi\u00e1trica \u2013 Aspectos f\u00edsicos e metab\u00f3licos do rec\u00e9m-nascido ao adolescente","author":"SMM Sugayama","year":"2002","unstructured":"Sugayama SMM, Kim CA: Anormalidades Cromoss\u00f4micas.
