Does elevated systolic blood pressure impact mortality and life expectancy in adults aged ≥25 years in Ningbo, China?
Elevated systolic blood pressure significantly contributes to mortality and loss of life expectancy in Chinese adults, highlighting the need for improved hypertension management.
Elevated SBP linked to major mortality and LE loss in Chinese adults; leaves open whether interventions improve outcomes in similar settings.
BACKGROUND: We aimed to analyse the impact of elevated systolic blood pressure (SBP) levels on mortality and life expectancy among ≥25 yr adults in the municipality of Ningbo, China. METHODS: The death cause data were collected from the Internet-based Comprehensive Chronic Disease Surveillance System in Zhejiang Province in 2015, and SBP level data were obtained from the Ningbo Adult Chronic Disease Surveillance survey. According to the comparative risk assessment theory, the population attributable fraction (PAF) of elevated SBP levels by gender and urban-rural regions has been calculated. The deaths and life expectancy loss due to elevated SBP levels were estimated. RESULTS: In 2015, the average SBP level among ≥25 yr adults in Ningbo was 129.01 ± 17.73 mmHg, which was higher in men (131.67 ± 16.89 mmHg) than in women (126.24 ± 18.15 mmHg) and was higher among adults in rural regions (130.55 ± 18.75 mmHg) than among adults in urban regions (127.15 ± 16.19 mmHg). A total of 6181 deaths were attributed to elevated SBP levels among adults in Ningbo. The PAF of deaths caused by elevated SBP levels among adults was 16.14%, which was higher in women (18.73%) than in men (14.31%). The overall loss of life expectancy caused by elevated SBP levels among adults was 1.76 yr, which was higher in women (1.99 yr) than in men (1.53 yr) and was higher in rural regions (1.91 yr) than in urban regions (1.49 yr). CONCLUSION: Elevated SBP levels had a serious impact on the death and life expectancy loss of residents in Ningbo.

Feng et al. (2021) conducted an observational in Elevated systolic blood pressure (n=4,800). Elevated systolic blood pressure vs. Theoretical minimum SBP level of 115 mmHg was evaluated on Population attributable fraction (PAF) of deaths caused by elevated SBP. Elevated systolic blood pressure was responsible for 6,181 deaths (16.14% of total deaths) and a life expectancy loss of 1.76 years among adults aged 25 and older in Ningbo, China in 2015.
