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 Purpose:
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<.001 and p=.015, respectively).
Conclusion: Through an analysis of national big data, this study found evidence that Korean girls showed a younger age at menarche in response to higher blood lead and mercury concentrations. To prevent and manage precocious puberty in Korean children and adolescents, a systematic policy that monitors both exposure to environmental hazards and blood heavy metal concentrations is needed.
