| Popis: | Although direct drinking water (DDW) systems that utilize a reverse-osmosis technique are thought to be harmful to children's development by reducing their daily mineral intake, few population data are available regarding this topic. We conducted an eco-epidemiological study to investigate the influence of low-mineral DDW on the development of schoolchildren. We collected developmental parameters of 13,723 girls and 16,161 boys before and after the introduction of DDW systems in 25 schools and measured the mineral levels in the DDW of each school. The DDW in 22 schools had lower-than-recommended levels of magnesium and calcium (magnesium, 10 mg/L and calcium, 20 mg/L, WHO). We found that children exposed to low-mineral DDW exhibited reduced height and diminished height increases as well as higher prevalences and incidences of hypoevolutism and dental caries (p |
