Implication

Reverses prior upward BP trends in US youth; leaves open dietary causality and durability beyond 2012.

Structured PICO

Population

14,270 US children and adolescents aged 8-17 years from the National Health and Nutrition Examination Survey (NHANES) 1999-2012.

Outcome

Trends in mean systolic and diastolic blood pressure levels and prevalence of elevated blood pressure and high blood pressure (HBP)surrogate

Contrary to previous upward trends, blood pressure levels and the prevalence of elevated blood pressure among US children and adolescents declined from 1999 to 2012, potentially associated with favorable changes in dietary factors.

Limitations

15.4% of participants had only 1 or 2 BP measurements instead of 3.
Average BP levels in a single visit were used instead of 3 repeated visits of different times, potentially overestimating prevalence.
24-hour recall questionnaire for dietary information may not fully capture long-term diet patterns or may introduce recall bias.
Unable to assess improvements in healthcare, parents' education, and overall children nutrition.
Causal relationships between influencing factors and BP decrease should be interpreted with caution.
Lack of data on physical activity and sedentary behaviors.
