Horton CJ, et al. - Through a population-based cross-sectional study that used data from the 2013–2016 National Health and Nutrition Examination Survey of 5,933 men and women (≥15 years), the researchers intended to discover the correlation between length of time in the USA with blood lead (BPb, continues to be a major public health concern both globally and within the USA and it adversely influences every organ system in the body, inhibiting enzymatic processes and inducing oxidative stress, but is particularly seen for its influence as a neurotoxin). Men only (n=2,867), women only (n=3,064) and women of childbearing age (15–45 years) (n=1,580) were recruited in this study. In comparison with women born in the USA, women of childbearing age who had resided 0–4 years in the USA had, on average, a 54% higher BPb. For all women, men and the entire population, corresponding outcomes were 49%, 49%, and 49%, respectively. For other time periods, similar, statistically meaningful, results were recognized and the magnitude of the correlation declined with increasing time in the USA. Hence, the additional proof was concluded by that newcomers to the USA could be a community at a greater risk of elevated BPb.
