Key result
The year 2016, compared to 2009, was associated with a substantial increase in the prevalence of hypertension from 28.4% to 39.5% (P < 0.01) in rural Southwestern China.
Why the study?
This study examines socioeconomic differentials in trends in hypertension and pre-hypertension prevalence, awareness, treatment, and control in rural Southwestern China.
Cross-Sectional (n=12,709)
In rural Southwestern China, hypertension prevalence significantly increased between 2009 and 2016, with improvements in awareness and control being disproportionately associated with higher socioeconomic status.

SES-linked gaps in hypertension awareness and control persisted despite rising prevalence in rural China; leaves open equity-focused longitudinal studies before guiding practice.
Background: This study examines the socioeconomic differentials in trends in the prevalence of hypertension and pre-hypertension and hypertension awareness, treatment, and control in rural Southwestern China.Methods: Two cross-sectional interviews and health examination surveys were administered in rural Yunnan Province, including 6,350 consenting participants in 2009 and 6,359 consenting participants in 2016 (aged ≥ 35 years). Participant demographics, socioeconomic status (SES), and ethnicity, along with information about hypertension awareness, treatment, and control, were collected using similar questionnaires in the two surveys. The participants’ blood pressure levels were also measured.Results: From 2009 to 2016, the prevalence of hypertension substantially increased from 28.4% to 39.5% (P < 0.01), and awareness and control rose from 42.2 and 25.8% to 53.1 (P < 0.01) and 30.6% (P < 0.05), respectively. Although people with a higher education level also had higher awareness and control rates than the lower education level ones, there were no conspicuous differences in the improvement of awareness and control between publics with different education levels over the 7 years studied. Increases were observed in both rates of awareness and control in people with a high level of income (P < 0.01). However, only the awareness rate increased in participants with a low level of income. Furthermore, the prevalence (P < 0.01) and treatment (P < 0.05) of hypertension were higher in the Han people than in ethnic minorities.Conclusions: Individual SES has clear associations with trends in the prevalence, awareness, and control of hypertension. Future interventions to improve hypertension prevention and control should be tailored to address individual SES.

Wang et al. (2020) conducted a cross-sectional in Hypertension and pre-hypertension (n=12,709). Time (2016 survey) vs. 2009 survey was evaluated on Prevalence of hypertension (p=< 0.01). The year 2016, compared to 2009, was associated with a substantial increase in the prevalence of hypertension from 28.4% to 39.5% (P < 0.01) in rural Southwestern China.
