© 2019 Elsevier GmbH Background: The objective of the study was to assess hair trace element and mineral content in children undergoing WFP UN and the governmental programs of school nutrition in Tajikistan. Methods: WFP program included provision or wheat flour fortified with micronutrients including Fe and Zn, and iodized salt, whereas within the governmental program hot meals were provided. A total of 202 children studying in schools that were not (Type 1, n = 100) or were involved in dietary intervention programs (Type 2, n = 102). Food and hair trace element content was assessed using ICP-MS. Results: Daily intake of Fe, I, Zn, B, Co, Mg, Si, and Sr in Type 2 schools was more than 2.5, 12, 4, 2.9, 2.6, 2, 3, and 2-fold higher than that in Type 1 schools. Correspondingly, anthropometric parameters in children from Type 2 schools exceeded the control values. Surprisingly, no significant difference in hair iodine levels was detected. Hair analysis demonstrated a significant increase in hair Ca, Mg, Na, Co, Cr, Cu, Fe, Li, Mn, Se, V, Zn content. Certain toxic elements including Al, As, and Be were also characterized by an increase in Type 2 schools. At the same time, nutritional intervention was associated with a significant decrease in hair B, Hg, and Sn levels. Conclusions: Nutritional intervention within WFP and the governmental program was effective in increasing essential trace element supply in Tajik schoolchildren. However, further studies including a detailed assessment of nutritional and health status with a special focus on iodine and thyroid functioning are required.

The authors have carried out a systems analysis of the data available in the current literature on the effect of micronutrients, such as iodine, polyunsaturated fatty acids, folic acid, and vitamin D, on a woman’s reproductive health. Due to its geographical location, climatic features, and eating habits, our country has the proven deficiency of a number of micronutrients that play an important role in the periconceptional period. These micronutrients include iodine, polyunsaturated fatty acids, folic acid, and vitamin D. The content of micronutrients should not exceed the physiological daily requirement in the basic complexes intended for the prevention of deficiency, The excessive content of components can cause undesirable reactions and contribute to the allergization of newborns. In clinically pronounced deficiency, the basal complex can be combined with a monocomponent vitamin preparation for the targeted correction of vitamin and mineral status.
