Nutritional Status and Iodized Salt Use Among School-aged Children

Iodine Deficiency Clinical Trial

Official title: Nutritional Status and Iodized Salt Use Among School-aged Children Living in Phu Kut City, Xieng Khouang Province, Lao PDR

Status Completed

Clinical Trial Summary

To determine and explore the iodized salt concentration provided in the local community, especially in the Phu Kut district whether it meets the standard or not. This district is located in a mountainous area which means that the local community confronts with geographical access due to the limited transportation and road condition, in addition, it is quite far from downtown approximately 26 kilometers and it is difficult to access the iodized salt consumption. On the other hand, since 2013, the Lao People's Democratic Republic has implemented the iodized survey of urine among the primary students, this time could be the chance to compare based on the previous data, which will be an important source of the data for certifying the quality of iodized salt available in the local community that could be one cause of lacking iodized salt intake. Furthermore, the investigators could conduct the survey and monitor the current action plan related to iodized consumption in Laos as well, in order to eradicate diseases concerning with lacking iodized salt intake. Objectives 1. To investigate the nutritional status of school-aged children (SAC) living in Phu Kut City, Xieng Khouang province. 2. To investigate the iodine status and iodized salt use of school-aged children (SAC) living in Phu Kut City, Xieng Khouang province.

Clinical Trial Description

Malnutrition Situation in Lao PDR. The Lao PDR has witnessed significant improvements in its Gross Domestic Product (GDP) for the past 2 decades. However, this does not commensurate with reductions in food insecurity and malnutrition (NNS, 2016). There exist significant disparities in income and living conditions between the rich and the poor; rural and urban dwellers; literates and illiterates (MOH-Lao PDR, 2014). Lao PDR has the highest prevalence of stunting in the ASEAN region with an estimated 33% of children under 5 years being too short for their age (stunted) and 9.6% acutely malnourished (LSIS, 2017). Whilst recognizing the marginal reductions in the prevalence of malnutrition, the rates are relatively higher than recommended thresholds and of public health significance. Micronutrient deficiency among the population is at an alarming level and calls for urgent action. 2 out of 5 children under 5 years are anemic and another 30% of preschool children are suffering from Vitamin A Deficiency (VAD). 36.2% of women in reproductive age are anemic with less than 20% of the general population consuming adequately iodized salt (LSIS, 2011-2012). In 2017, it can be seen that in the whole country, there are households that consume iodized salt increased to 89.2%, specifically in Xieng Khouang province it is 87.6% (LSIS, 2017). Most recently in 2018, according to the monitoring report on the quality of iodized salt of the Department of Food and Drug, the Ministry of Health conducted a survey to check the quality of iodized salt in 8 provinces: Vientian capital (Vernkham salt factory), Vientiane province (Ban Bor salt factory), Lung Namtha province (Boten salt factory), Oudomxay province (Elephant brand salt factory), Borikhamxay (Song Kone Salt factory), Savannakhet (Natei Salt factory, Kasay Salt factory and Kasay Thip salt factory), Xieng Khouang province and Huaphan province (imported salt, market salt and household salt). This report found that only 2 out of 9 salt factories produced iodized salt according to the standard (40 ppm -60 ppm) namely Vern Kham Salt Factory and Salt Factory, almost 80% of factory machinery is dilapidated, lack of improvement, looking for spare parts for injectors, there is no place to sell them, lack of mixing techniques and iodine is expensive. In the Xieng Khouang province, there is no any iodized salt factory, the local people just consumed the imported products. but they could detect the iodized salt concentration selling in the market and in the household. The results from iodized salt testing from 5 target districts have been done from the sampling in the district for a total of 125 samples from 10 trade names of the iodized salt. Unfortunately, there is no iodized salt trade name that meets the standard. Referring to the detail of the trade name and results of iodized salt testing below from five target districts: No Iodized salt brand name Factory Iodine content (ppm) 1. Iodize salt (spoon tradename) Koksaath 34.8 2. Iodize salt (spoon tradename) Koksaath 23.8 3. Iodize salt (spoon tradename) Koksaath 26.7 4. Iodize salt (spoon tradename) Koksaath 1 5.
