Divergent secular trends in blood pressure and body mass index in children and adolescents in Hong Kong

Abstract Secular trends in blood pressure (BP) and body mass index (BMI) during childhood and adolescence are sentinels for the future population cardiovascular disease burden. We examined trends in BP z-score (ages 9–18 years from 1999 to 2014) and BMI z-score (ages 6–18 years from 1996 to 2014) in...

We examined trends in BP z-score (ages 9–18 years from 1999 to 2014) and BMI z-score (ages 6–18 years from 1996 to 2014) in Hong Kong, China.

However, the trends were not consistent, for both sexes, systolic BP z-score was stable from 1999, decreased slightly from 2002 to 2005 and increased slightly to 2014, diastolic BP z-score decreased slightly from 1999 to 2004 and then remained stable to 2014.
