PARMA, R et al. CABE-FASEN Report: Screening of Disorders Associated with lodine Defciency in the Province of Santa Fe, Argentina (2007). Rev. argent. endocrinol. metab. [online]. 2013, vol.50, n.3. ISSN 1851-3034.

A total of 1,470 primary school students were evaluated to monitor the prevalence of endemic goiter in four cit-ies of Santa Fe province: Reconquista (404) and Villa Ocampo (294) situated in the north, and Rufino (317) and Venado Tuerto (455) situated in the south of the province. Their age ranged from 6 to 14 years. Neck palpation was performed in all students; for the sake of consistency with monitoring performed in other provinces, palpation was performed by only one physician (HN). The goiter grading system was the same used in other surveys. After palpation, urine samples for iodine determination were randomly collected (109 from Reconquista, 105 from Villa Ocampo, 113 from Rufino and 139 from Venado Tuerto). Iodine was also measured in salt samples collected from the children's homes (337 from Reconquista, 227 from Villa Ocampo, 295 from Rufino and 422 from Venado Tuerto). Prevalence of goiter was 2.6 % without differences among cities. Urine iodine levels were significantly different between northern and southern cities: Reconquista had a mean of 238.6 ± 116 µg/L (median 213 µg/L) and Villa Ocampo had a mean of 241.6 ± 223.5 µg/L (median 188 µg/L), while in Rufino the mean was 544 ± 349 µg/L (median 442 µg/L) and in Venado Tuerto it was 550 ± 375 µg/L (median 418 µg/L; mean ± SD). Iodine contents in salt were similar across the province, with a mean of 35.5 mg/kg. Prevalence of salt samples with iodine concentration <15 mg/kg was 0.3 % in Reconquista, 1.3 % in Villa Ocampo, 3 % in Rufino, and 4 % in Venado Tuerto. We conclude that the province of Santa Fe, Argentina, is free from endemic goiter. No financial conflicts of interest exist.
