Iodine Status of the Indigenous Peoples (Karen) Living in Thailand

Status Completed

Clinical Trial Summary

In describing the iodine status involving health conditions of the minority groups, this observational study aims to learn about the iodine status of the Indigenous Peoples (Karen) in a subdistrict in western Thailand. The Participants will be collected their urine to determine urinary iodine concentrations At the same time, their household salt will be also collected to determine iodine content.

Clinical Trial Description

Iodine deficiency (ID) is a global public health problem, and it is estimated that almost 240 million school-aged children (SAC) worldwide have an insufficient iodine intake. Currently, severe ID is uncommon, but mild-to-moderate ID is still widespread on a global level, especially in the Asia region. Iodine deficiency causes multiple adverse effects on growth and development in all age groups. Salt iodization is recommended as the most cost-effective way of delivering iodine to the target population to combat iodine deficiency. In addition, the cyclic monitoring of urinary iodine concentration (UIC) in vulnerable groups is recommended by the World Health Organization (WHO). However, some minority communities such as indigenous peoples living in remote rural areas are not included in IDD surveillance programs. Indigenous peoples in many developing countries, including Thailand, are largely ignored in development efforts, as they are disadvantaged minority groups in those societies. These indigenous peoples may therefore be at risk of many adverse health and nutrition consequences, resulting in their quality of life. In order to promote nutrition and health, and to ensure adequate iodine intake among indigenous peoples in Thailand, it is essential to understand the urinary iodine concentration of the populations and the iodine content in their household salt. The results from this study could then be considered and potentially strengthen the Universal Salt Iodization (USI) program in Thailand, to reach indigenous peoples in border areas. This study will conduct in Karen communities in Laiwo Subdistrict, Sangkhlaburi District, Kanchanaburi Province, Thailand. The participants will be divided into 2 groups, school-aged children, males and females (6-12 years), and women of reproductive age (15-49 years). The Participants will be collected their urine to determine urinary iodine concentrations At the same time, their household salt will be also collected to determine iodine content. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
