The correlation between age and serum β
2-MG levels and between age and urinary β
2-MG levels of Japanese was studied, and the results were as follows.
1. The correlation coefficients between age and β
2-MG level in the serum were +0.240 for males, +0.448 for females and +0.303 for both sexes.
2. The correlation coefficients between age and actual β
2-MG level in the urine were +0.321 for males, +0.294 for females and 0.288 for both sexes.
3. The correlation coefficients between age and β
2-MG level corrected for creati-nine in the urine were +0.265 for males, +0.423 for females and +0.345 for both sexes.
4. The correlation coefficients between age and β
2-MG level corrected for density in the urine were +0.278 for males, +0.315 for females and +0.298 for both sexes.
5. The correlation coefficients between cadmium level and β
2-MG level in the urine were +0.075 for males, +0.618 for females and +0.441 for both sexes.
6. The correlation coefficients for items (1) to (5) were significantly different from zero (p<0.05).
