Implication
Supports dietary/BMI factors explaining north-south BP differences in China; hypothesis-generating for interventions, needs prospective confirmation.
Structured PICO
Do dietary factors account for the blood pressure differences between northern and southern Chinese populations?
P
Population
839 Chinese participants (561 northern, 278 southern), aged 40 to 59 years, from the International Study on Macronutrients and Blood Pressure (INTERMAP).
I
Intervention
Dietary factors (including sodium, potassium, magnesium, phosphorus intake, and body mass index)
C
Comparator
Comparison between northern and southern Chinese populations
O
Outcome
Systolic and diastolic blood pressure differencessurrogate
Multiple dietary factors and body mass index largely account for the higher blood pressure observed in northern compared to southern Chinese populations.
