| Popis: | Purpose This study utilized data from the Korean National Health and Nutrition Examination Survey (KNHANES) to explore differences in the timing of menarche in Korean girls according to blood heavy metal concentrations. Methods This study performed a secondary analysis of cross-sectional data from the sixth KNHANES. Data from 179 female children and adolescents aged 10~18 were included in this study. The relationships of blood heavy metal concentrations (lead, mercury, and cadmium) with age of menarche were analyzed using complex sample multiple logistic regression. Results In the participants of this study, the geometric mean values of blood lead, mercury, and cadmium concentrations were 1.15±0.04 μg/dL, 1.80±0.08 μg/L, and 0.30±0.03 μg/L, respectively. Mercury poisoning (>5 μg/L) was found in 1.5% of participants. Furthermore, significant relationships were found between blood lead and mercury concentrations and age at menarche (p for trend: p |
