Abstract
Iodine deficiency (ID) is recognized as a leading risk factor for child development. Universal salt iodization (USI) is an effective and well-established intervention strategy for the prevention of iodine deficiency disorders (IDD). To evaluate the levels of iodine in household salt samples and the urinary iodine concentration (UIC) in schoolchildren aged 6 to 14 years in public schools in Bahia, Brazil. A cross-sectional study was conducted with 1231 students (6 to 14 years old) from 17 public schools in Bahia. The iodine concentration was evaluated in salt and UIC samples. The adapted Sandell-Kolthoff reaction was used to determine urinary iodine levels. A spectrophotometer (UV-Vis) was used to examine the reduction of ceric ammonium sulfate. A standard iodine solution using a potassium iodate was used to extrapolate the iodine concentrations. The total of 665 salt samples had a median iodine concentration of 24 mg/kg (25th-75th percentile 17.0 to 28.5 mg/kg). The largest proportion (79.6%) of salt samples had iodine concentration in the recommended range, 17.6% of the samples presented iodine at a salt concentration below the established level (<15 mg/kg) and a small proportion was above it (2.8%). The general mean urinary iodine concentration (MUIC) was 217.53 ± 28.30 μg/L and median was 205.50 μg/L. The students evaluated and the salt samples analyzed showed satisfactory results, as recommended by Brazilian legislation and nutritional recommendations of the World Health Organization (WHO).

Pavlova N, Filippova E. The co-relation of eating behavior and body image formation in children and adolescents in the context of child-parent relationships. СОВРЕМЕННАЯ ЗАРУБЕЖНАЯ ПСИХОЛОГИЯ 2020. [DOI: 10.17759/jmfp.2020090403] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 12/12/2022]
Abstract
The review presents foreign works aimed at studying the effects of parental and societal behavior on eating behavior and attitudes towards their bodies in children and adolescents. The reviewed articles analyze attitudes towards the bodies and internalized appearance patterns in children and adolescents, formation of their patterns of healthy eating and healthy eating behavior, and do not focus on eating disorders only. It must be noted that in Russia the issue of healthy eating behavior is touched upon mainly in publications concerning the medical aspect of this problem, while in foreign psychological studies it is becoming increasingly popular. The analysis of the publications also shows that the problem of eating behavior and attitude to the body, traditionally related to adolescence, is clearly "rejuvenated". Children aged 6-7 are gradually becoming the target group of researchers, so the problem deserves serious attention.
