Gaps in awareness and control of hypertension: a cross-sectional study in Chinese urban adults.

Hypertension is a serious public health threat worldwide. This study sought to explore gaps in urban Chinese adults' awareness and control of hypertension. A cross-sectional study was carried out in eight Chinese cities in 2016. Participants were organized into four groups on the basis of blood pressure (BP) and self-reported disease history: healthy group (63.0%), well-controlled BP group (9.1%), unaware hypertension group (14.0%), and poorly controlled BP group (13.9%). Multinomial logistic regression with the healthy group as the reference group showed that younger age and body mass index <24 kg/m were negatively associated with lack of awareness of hypertension and poor control of BP. Lower salt intake, but not sodium intake, was associated with poor control of BP. Other factors associated with lack of awareness of hypertension included low fish and seafood intake. Low sodium intake contributed to good control of BP. In conclusion, there are gaps in urban Chinese adults' awareness and control of hypertension. A comprehensive strategy for enhancing awareness of hypertension and changing behaviors associated with the condition should be developed and implemented.
