The importance and effectiveness of nutritional counselling in patients with autoimmune thyroid diseases in Poland

BACKGROUND: Autoimmune thyroid diseases are the most common diseases in humans. Their pathogenesis is complex, pushing patients to search different ways of alleviating their effects, one of which is diet change. The aim of this study was to assess the role of medical personnel in shaping eating habits in patients with autoimmune thyroid disease based on experiences declared by patients. METHODS: We examined 208 individuals, of which 205 were qualified for final investigation. We selected study participants using accidental sampling, based on their appearance in health care facilities, including the ones providing endocrinological advices. The relationships between the qualitative features were tested using the Chi-square test of independence, assuming the significance level of p < 0.05. In the case of the expected cardinality < 10, the Chi-square test with correction for Yates continuity was used, while for the cardinality < 5—the Fisher exact test. RESULTS: People with thyroid disease are statistically more likely to use dietitian advice than people without thyroid disease. The highest percentage of respondents decided to modify their nutrition due to their own initiative. In addition, patients with autoimmune thyroid disease are statistically more likely to consider changing their diet to improve their well-being. The connection between the source of advice and modification of eating behaviour was also noted. CONCLUSION: Thanks to the joint effort of medical staff, patients can receive reliable knowledge about their disease, treatment and nutrition adapted to their needs.
