These results suggest that in children, just as in adults, obesity is related to a relatively decreased dipping in nocturnal BP.

Recent data has shown that ABPM is more strongly associated with end-organ damage than casual BP, and that obesity and secondary causes of hypertension are strongly associated with nocturnal hypertension. There is evidence that ABPM is useful in management of a larger variety of diagnoses than previously thought. New guidelines from the American Academy of Pediatrics recognize the importance of ABPM in the management of pediatric hypertension. ABPM has an important and growing role in the diagnosis and management of hypertension in children and adolescents. Future efforts should include developing more generalizable normative data and investigating associations between pediatric ABPM results and adult outcomes.

Our results demonstrate a positive association between maternal obesity and CAKUT in offspring, as well as between obesity severity and the odds of CAKUT in offspring. These findings provide additional evidence for the public health importance of obesity, particularly as a potentially modifiable risk factor.
