研究概览
简要总结
Hashimoto's disease is listed among the most common endocrine causes of obesity. As treatment of obesity in women with Hashimoto's disease is frequently unsuccessful, the aim of this study was to evaluate the effectiveness of two different reducing diets and their influence on changes in thyroid parameters in the female patients. A six-month observational/interventional study was performed on 100 women aged 18-65 years, previously diagnosed with Hashimoto's disease and obesity and receiving L-thyroxine. The women were randomly assigned to the test group (group A, n=50) following elimination/reducing diets, and the control group (group B, n=50) following reducing diets with the same caloric content (without elimination). Anthropometric and thyroid parameters were evaluated at the beginning, after 3 months and after 6 months of treatment.

研究组 & 干预措施
Test group (group A)
The women were randomly assigned to group A. Test group included 50 women aged 18-65 years with previously diagnosed Hashimoto's disease and obesity. Hashimoto's disease (AITD) was diagnosed by a specialist based on the ultrasound image characteristic of AITD and high levels of anti-thyroid antibodies.
干预措施: Individually balanced elimination/reducing diets (Behavioral)
Control group (group B)
The women were randomly assigned to group B. Control group included 50 women aged 18-65 years with previously diagnosed Hashimoto's disease and obesity. Hashimoto's disease (AITD) was diagnosed by a specialist based on the ultrasound image characteristic of AITD and high levels of anti-thyroid antibodies.
干预措施: Individually balanced reducing diets (without elimination) (Behavioral)

主要结局
Effect of reducing/elimination diets based on IgG1-3 food sensitivity tests and standard balanced reducing diets on body weight changes in patients from obesity and Hashimoto's disease.
时间窗: This measurement was repeated during 3 visits every 12 weeks.
The body weight (kg) was measured using a scale with a stadiometer.
Effect of reducing/elimination diets based on IgG1-3 food sensitivity tests and standard balanced reducing diets on body weight changes in patients suffering from obesity and Hashimoto's disease.
时间窗: This measurement was repeated during 3 visits every 12 weeks.
The height (cm) was measured using a scale with a stadiometer. This measurement is needed to calculate the Body Mass Index.
Effect of reducing/elimination diets based on IgG1-3 food sensitivity tests and standard balanced reducing diets on Body Mass Index changes in patients suffering from obesity and Hashimoto's disease.
时间窗: This measurement was repeated during 3 visits every 12 weeks.
Body Mass Index (kg/m\^2) was calculated from the measurements of height and weight using a mathematical formula.
Effect of reducing/elimination diets based on IgG1-3 food sensitivity tests and standard balanced reducing diets on changes in muscle mass in patients suffering from obesity and Hashimoto's disease.
时间窗: This measurement was repeated during 3 visits every 12 weeks.
Muscle mass (kg) was determined using the bioimpedance method with a TANITA BC-420 body composition analyzer (T6360, Japan).

Effect of reducing/elimination diets based on IgG1-3 food sensitivity tests and standard balanced reducing diets on changes in thyroid parameters in patients suffering from obesity and Hashimoto's disease.
时间窗: This examination was repeated during 3 visits every 12 weeks.
Laboratory tests were performed to determine the following serum levels: TSH, fT3, fT4, anti-TPO, and anti-TG. Blood samples were collected in an accredited medical laboratory, in the morning, on an empty stomach after a 12-hour fast.
