High Water Iodine Concentrations Are Associated With the Prevalence of Subclinical Hypothyroidism, Thyroid Nodules, and Goiter Among Pregnant Women in Shandong, China.

Background: Both iodine deficiency and iodine excess can harm the thyroid glands during pregnancy. In areas without iodine fortification, the relationship between the water iodine concentration (WIC) and thyroid disease in pregnant women requires further investigation.

Objectives: The aim of this study was to evaluate the relationship between WICs and the prevalence of thyroid disease in pregnant women residing in areas with high WICs without access to iodized salt.

The relationship between psychological distress and weight maintenance in weight cycling: mediating role of eating behavior.

Background: Obesity is a global public health concern. The goal of this study was to see if eating habits could mediate the relationship between psychological distress and weight maintenance in a population with a history of weight cycling.

Methods: A 3-month outpatient intervention consisting of a diet and exercise program was provided to 153 participants.

Iodine Intakes of <150 μg/day or >550 μg/day are Not Recommended during Pregnancy: A Balance Study.

Background: Adequate iodine intake during pregnancy is critical for maintaining maternal and fetal thyroid function and development. There are only limited data from iodine-balance studies to inform iodine requirements during pregnancy.

Objectives: This is an iodine-balance study conducted to explore the associations among iodine intake, excretion, and retention to provide information regarding iodine requirements during pregnancy.

New Reference Values for Thyroid Volume and a Comprehensive Assessment for Influencing Factors in Chinese Adults with Iodine Sufficiency.

Objectives: The reference values for thyroid volume (Tvol) determined by ultrasound require supportive data of normal Tvol from local iodine-sufficient populations. This study aimed to explore new reference values for Tvol in Chinese adults and comprehensively evaluate the factors associated with enlarged Tvol.

Methods: A cross-sectional study was conducted in Tianjin, China.

Evaluation of variation of saliva iodine and recommendations for sample size and sampling time: Implications for assessing iodine nutritional status.

Background: Saliva iodine concentration (SIC) has been found to be a good indicator of iodine nutritional status. However, limited information is available regarding saliva iodine characteristics.

Aims: The study aimed to evaluate intra-day, intra-individual, and population SIC variation in order to provide information on optimal sample size and sampling time for assessing iodine nutritional status.

Saliva Iodine Concentration in Children and Its Association with Iodine Status and Thyroid Function.

Context: The effectiveness of saliva iodine concentration (SIC) in evaluating iodine status in children is not clear.

Objective: We aimed to explore associations between SIC and assessed indicators of iodine status and thyroid function.

Design: Cross-sectional study.

Intra-individual and inter-individual variations in iodine intake and excretion in adult women: implications for sampling.

Iodine intake and excretion vary widely; however, these variations remain a large source of geometric uncertainty. The present study aims to analyse variations in iodine intake and excretion and provide implications for sampling in studies of individuals or populations. Twenty-four healthy women volunteers were recruited for a 12-d sampling period during the 4-week experiment.
