This national cross-sectional survey aimed to assess the iodine status in pregnant women and their offspring, and also to demonstrate regional differences by measuring urinary iodine concentration (UIC). For each woman and her newborn a questionnaire was prepared with basic facts as age, parity number or birth weight and additional information regarding thyroid diseases, use of iodized salt in the household, extra iodine supplementation during pregnancy, education level and wage income. The target population represented 1444 pregnant women who gave birth between January 1 st, 2018 and 2019, and their offspring. Iodine deficiency for pregnant women and their offspring were defined as urine iodine level <150 μg/L and <100 μg/L, respectively. Results are given as median (25th-75th percentile). The median UIC in the group of pregnant woman was 94 (52-153) μg/L. Within the sample of 1444 pregnant women, UIC indicative of mild iodine deficiency (100-149 μg/L) was present in 21 % (n = 306), moderate deficiency (50-99 μg/L) in 30 % (n = 430), and severe deficiency (<50 μg/L) in 23 % (n = 337). This study showed a prevalence of 74 % of iodine deficiency in Turkish pregnant woman. The median UIC in the group of offspring was 96 (41-191) μg/L. Within the new-borns, UIC indicative of mild iodine deficiency (50-99 μg/L) was present in 22 % (n = 323), moderate deficiency (20-49 μg/L) in 15 % (n = 222), and severe deficiency (<20 μg/L) in 13 % (n = 192). This survey showed a prevalence of 51 % of iodine deficiency in Turkish new-borns. Pregnant women with lower socioeconomic and education level, lower access to household iodized salt, lower rates of exposure to povidone-iodine containing skin disinfectant, higher parity and higher iodine deficiency had higher rates of iodine deficiency in their offspring. Regional differences were observed both in mothers and their offspring concerning their iodine status. Our findings suggest that iodine deficiency is still an important public health problem in Turkey. More drastic measures should be taken to decrease these important iodine deficiencies, both in pregnant women and in their offspring.

Consumers’ conviction of the benefits of probiotics is influenced by their existing beliefs and by the information they receive from healthcare professionals. The attitude of healthcare professionals towards commercially available probiotics will, therefore, determine how trustworthy and beneficial these products are perceived by consumers. Furthermore, due to European Union legislation, companies are prohibited from displaying information on product packaging; therefore, consumers are dependent primarily on healthcare professionals for correct information and guidance on the use of these products. The aim of this pilot study was to explore the understanding and use of probiotics in clinical practice by professionals who are involved in child healthcare in different European countries and to assess how much they value the scientific evidence behind these products. The study was performed using a cross-sectional, descriptive, 30-question online questionnaire circulated among healthcare professionals belonging to three professional categories that are typically involved in childhood probiotic prescription: paediatricians, dieticians and general practitioners. The questionnaire was developed using web-based standard guidelines, and the questions were modelled on those used in previously published probiotics studies. Overall, 27,287 healthcare professionals belonging to three major European scientific societies were contacted by the organizations participating in the study. In total, 1360 valid questionnaires were recorded, and the results were statistically analysed. The results emphasize the importance for healthcare professionals to be properly educated and updated on probiotics. An improved knowledge about probiotics led to increased prescriptive confidence. To disseminate accurate information on probiotics, healthcare professionals look for appropriate and scientifically validated educational platforms to acquire information, explore concerns and barriers and look for positive approaches towards recommending probiotics.
