Blood lead level and its association with body mass index and XXXX in China - Results from SPECT-China study.

@entity1 @entity579 @entity28
UNASSIGNED: We aimed to report environmental and blood lead level (BLL) in China, and investigate the relationship of BLL with body mass index (BMI) and @entity28 . 5558 subjects were enrolled from 16 sites in China. BLL was measured by atomic absorption spectrometry. Obesity was defined as BMI   >=    30   kg/m(2). Median (interquartile range) of BLL was 44.00    g/L (29.00-62.16) for @entity1 and 37.79    g/L (25.13-54.35) for @entity1 , about twice higher than in U.S. POPULATION: Subjects in rural and high-economic-status areas had significantly greater BLL (P   <   0.001). However, in these areas, the lead levels in drinking water, river water and @entity579 were comparable to or significantly lower than those in urban and low-economic-status areas. After adjustment for age, urbanization, economic status and metabolic factors, BLL was independently associated with BMI in @entity1 (P for trend   <   0.001), but not in @entity1 . In fully adjusted model, increased quartiles of BLL were associated with significantly increased odds ratios of @entity28 (P for trend   <   0.01) in @entity1 . In conclusion, BLLs in Chinese adults were much higher than in developed countries. There was a sex-specific association between BLL and BMI. Elevated BLL does not appear to be associated with lead levels in drinking water or @entity579 , suggesting some other exposure source.
