AbstractThe aim of this cross-sectional study in Jordan was to estimate the prevalence of hypothyroidism among women during early pregnancy and to assess the association of risk factors with hypothyroidism. According to internationally adopted thyroid stimulating hormone [TSH] and thyroxine [T4] pregnancy reference ranges [TSH >/= 2.6 mIU/L and T4 10.6-20.4 pmol/L], 67 of 322 [20.8%] women were diagnosed with sub-clinical hypothyroidism. When the general laboratory criteria were applied [TSH >/= 4.6 mIU/L and T4 < 10.6 pmol/L] the prevalence dropped to 4.3%. No cases of overt hypothyroidism were diagnosed using either diagnostic criterion. Younger age and being in gestational weeks 1-8 were significant risk factors for hypothyroidism. It is suggested that the reference criteria need revision, and that pathology laboratories should adopt appropriate pregnancy specific reference intervals

Hashemipour, M.; Amini, M.; Talaie, M.; Kelishadi, R.; Hovespian, S.; Iranpour, R.; Salek, M.; Haghigh, S.; Khatibi, K.H. (2007)We determined the prevalence of congenital hypothyroidism and the rate of consanguinity among parents of hypothyroid neonates among 93 381 neonates born in 17 hospitals in Isfahan from May 2002 to April 2005. Serum thyroxine [T4] and thyroid stimulating hormone [TSH] levels were measured on the 3rd-7th day of birth and neonates with abnormal levels were recalled and the levels reassessed. Those with TSH </= 10 mIU/L and T4 < 6.5 micro g/dL on the second assay were considered hypothyroid. In all, 1038 neonates were recalled and 274 were diagnosed ...
Prevalence of iodine deficiency disorders in the United Arab Emirates measured by raised TSH levels Al Hosani, H.; Osman, H.; Abdel Wareth, L.; Saade, D.; Salah, M. (2003)The United Arab Emirates National Screening Programme for Congenital Hypothyroidism was established in January 1998. The programme measures neonatal thyroid-stimulating hormone [TSH] levels of blood samples collected on filter paper on day 5 by heel prick. The prevalence of raised TSH levels [> 5 microU/mL whole blood] during 1998 and 1999 was used to evaluate the degree of iodine-deficiency disorders [IDD] in the population in different regions. The ratio of TSH profile in the present study and goitre rate in schools in a 1994 study were discrepant, ...
