ABSTRACT

Little is known about iodine nutritional status in island countries in the Pacific Ocean. The primary objective of this study was to report for the first time the iodine nutritional status of people in Nauru. In addition, sources of iodine nutrition (i.e., water and salt) were investigated. A school-based cross-sectional survey of children aged 6–12 years was conducted in three primary schools of Nauru. Urinary iodine concentration (UIC) was determined by spot urine samples. Available water and salt samples in Nauru were collected for the measurement of iodine content. A food frequency questionnaire was conducted. The median UIC was 142 μg/L, and 25.2% and 7.4% of the population had median UIC below 100 μg/L and 50 μg/L, respectively. Natural iodine-containing foods such as seaweeds and agar were rare. Iodine was undetectable in Nauruan tank water, filtered tap water, and raindrops. Of the analyzed salt products, five kinds were non-iodized, and three were iodized (iodine content: 15 ppm, 65 ppm, and 68 ppm, respectively). The results indicate that the iodine status in Nauruan school children is adequate. Iodized salt may serve as an important source of iodine nutrition in Nauru.

Mentions: This survey was a collaborative initiative between the Nauru Ministry of Health, Taiwan Ministry of Foreign Affairs, and Taipei Veterans General Hospital, Taiwan. Ethical approval was granted by the Nauru Non-communicable Disease Steering Committee, Nauru Ministry of Health (20150917). This research was designed as a school-based survey to collect nationally representative data of iodine status in Nauru. All three primary schools (Yaren Primary School, Nauru Primary School, and Kayser College, Figure 1) in Nauru with students aged 6–12 years participated in the study. Participating students were randomly selected by the Statistics Division of the Ministry of Education, Nauru, to represent their age, gender, and region of residence. Students were asked to provide a random spot urine sample and fill out a short Food Frequency Questionnaire (FFQ). Informed consent was signed by one of the parents of the enrolled school children. A total of 242 students (126 males, 116 females) aged 6–12 years successfully participated in this study. To determine the source of iodine nutrition, water samples from different regions were collected and analyzed. The iodine content in salt products in Nauru was also measured.
