Anthropometric evaluation, hormonal and lipid assays, oral glucose tolerance test (OGTT) and euglycaemic\u2013hyperinsulinaemic clamp were performed. Hirsutism was assessed with the Ferriman\u2013Gallwey (FG) score.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Main results<\/jats:title>\n<jats:p>SCH was found in 14% of PCOS subjects and in 1% of controls (P\u2009&lt;\u20090.01). In PCOS women, TSH levels were directly correlated with fasting glycaemia, but not with other hormonal and metabolic parameters. When PCOS patients were classified on the basis of BMI, TSH levels significantly correlated with insulin secretion, insulin resistance, DHEAS and cortisol levels in obese PCOS women. Inverse correlations were found between TSH and both oestradiol and SHBG in the same group. In nonobese PCOS patients, only waist-to-hip ratio values were correlated with TSH. The prevalence of SCH was not different between nonobese and obese PCOS groups (14 and 15% respectively). However, SCH was associated with higher levels of insulin, DHEAS, cortisol and FG score only in the obese subgroup.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Our data confirm that the prevalence of SCH is increased in PCOS women. The presence of SCH is associated with endocrine and metabolic imbalances of PCOS, and the excessive body weight seems to promote this interplay.<\/jats:p>\n<\/jats:sec>","DOI":"10.1530\/eje-16-0358","type":"journal-article","created":{"date-parts":[[2016,8,11]],"date-time":"2016-08-11T02:39:35Z","timestamp":1470883175000},"page":"433-441","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-1","source":"Crossref","is-referenced-by-count":28,"title":["The link between metabolic features and TSH levels in polycystic ovary syndrome is modulated by the body weight: an euglycaemic\u2013hyperinsulinaemic clamp study"],"prefix":"10.1093","volume":"175","author":[{"given":"Valeria","family":"Tagliaferri","sequence":"first","affiliation":[{"name":"1Department of Obstetrics and GynaecologyUniversit\u00e0 Cattolica del Sacro Cuore, Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Romualdi","sequence":"additional","affiliation":[{"name":"1Department of Obstetrics and GynaecologyUniversit\u00e0 Cattolica del Sacro Cuore, Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maurizio","family":"Guido","sequence":"additional","affiliation":[{"name":"1Department of Obstetrics and GynaecologyUniversit\u00e0 Cattolica del Sacro Cuore, Roma, Italy"},{"name":"2Department of Obstetrics and GynaecologyEnte Ecclesiastico Ospedale Generale Regionale \u201cF.
