Implication

Persistent regional gaps in hypertension care may sustain excess CV risk in China; leaves open causal drivers and targeted intervention effects.

Structured PICO

P
Population
13,725 Chinese residents aged 45 and older from the China Health and Retirement Longitudinal Study (CHARLS) baseline in 2011, with follow-ups in 2013 (n=10,893) and 2015 (n=11,675).
O
Outcome
Rates of undiagnosed, untreated, and uncontrolled hypertension

While hypertension diagnosis, treatment, and control in China improved significantly between 2011 and 2015, substantial geographic and socioeconomic disparities persist, highlighting the need for targeted regional interventions.

Limitations

  • Institutionalized population was not included in the survey
  • Conducted in only 28 provinces, with data of 6 provinces missing
  • Average age of the panel increased by roughly 2 years in each follow-up survey, potentially impacting prevalence estimation
  • About 20% of participants did not report their blood pressure readings in all three survey rounds
