[Iodine deficiency in Southern Badenia--changes during the last 55 years].

Despite the voluntary iodine prophylaxis in Germany no significant change in the iodine supplementation was observed in the last two decades in Southern Badenia. This finding relates to urinary iodine excretion as well as to goiter prevalence and thyroid volume. The comparison with studies from the 30es and 50es shows significant changes, however. There were relevant regional differences in goiter prevalence and iodine supply in Southern Badenia at that time. The supply of more iodine-containing food could be improved for all walks of life by raising the general standard of life. Actually, there are no longer regional differences in iodine supply and goiter volume in Southern Badenia. However, in 95% of patients investigated the urinary iodine excretion is still below the minimum of 150 micrograms iodine/g creatinine recommended by WHO.
