“…These findings therefore suggest that young asymptomatic children, particularly of black ethnicity, are susceptible to the early development of elevated BP and complications associated with renal function. Previously, hypertension and its adverse after-effects were mainly attributed to adults and rare in children [46]. More recently, secondary causes of hypertension are mostly found in children where renal and renovascular diseases are among the most identifiable precursors of childhood hypertension [47].…”

Objectives and methods: Hypertension is a growing health concern in childhood populations and individuals of African descent. As the kidneys play a significant role in blood pressure regulation, we compared alpha-1 microglobulin (A1M) as a marker of proximal tubular function between young healthy black and white children (n ¼ 957; aged: 5-9 years) and explored its association with blood pressure.Results: The black children had higher levels of A1M (P < 0.001) and higher DBP (P < 0.001) when compared with their white counterparts. In multiple regression analysis, SBP (adj. R 2 ¼ 0.173, b ¼ 0.151; P < 0.001) and DBP (adj. R 2 ¼ 0.110, b ¼ 0.179; P < 0.001) associated positively with A1M in the black children. In binary logistic regression, each standard deviation increase in A1M increased the odds of having elevated blood pressure by 28% (P ¼ 0.002) in the black group, independent of age, sex, BMI z-score and body height. No significance was reached in the white children. Conclusion:Our findings highlight the importance of a marker of proximal tubular function, especially in children of black ethnicity, in the setting of elevated blood pressure. Early childhood screening for elevated blood pressure remains essential in order to promote primary prevention of hypertension and early onset kidney damage in children.
