Age-Depending Relationships between Blood pressure and you can Intellectual Impairment: A corner-Sectional Studies into the an outlying Area of Xi’an, China

Hypertension is a convertible chance foundation to own cognitive handicap, although the matchmaking ranging from blood pressure level and cognitive disability is not totally know. The objective of this study were to investigate the effect from many years to your relationships anywhere between blood pressure and you can intellectual handicap.


Blood circulation pressure and you will globally intellectual form suggestions are amassed regarding 1799 participants (ages forty–85) just who lived in a town regarding the suburbs out-of Xi’an, Asia, during inside the-people interviews. Intellectual impairment is identified as a micro-Mental state Test (MMSE) rating below the new cutoff worthy of. The outcome of age towards the relationships ranging from hypertension variables [systolic blood pressure level (SBP), diastolic blood pressure level (DBP), imply arterial blood circulation pressure (MABP), and high blood pressure levels (HBP, SBP?140 mm Hg and you may/or DBP?ninety mm Hg)] and you may cognitive impairment was assessed of the logistic regression habits having fun with telecommunications and you may stratified analysis. Blood pressure levels and you may ages were considered to be both proceeded and you may categorical research.


A total of 231 participants were diagnosed as having cognitive impairment based on our criteria. Interaction analysis for the total population showed that SBP (when regarded as continuous data) was positively correlated with cognitive impairment (OR = 1.130 [95% CI, 1.028–1.242] per 10mmHg, P = 0.011); however, the age by SBP interaction term was negatively correlated ardent with cognitive impairment (OR = 0.989 [95% CI, 0.982–0.997] per 10mmHg?year, P = 0.006), indicating that the relationship between SBP and cognitive impairment was age-dependent (OR = 1.130?0.989 (age-55.5) per 10mmHg,40 ?age?85). When the blood pressure and age were considered as binary data, the results were similar to those obtained when they were considered as continuous variables. Stratified multivariate analysis revealed that the relationship between SBP (when regarded as continuous data) and cognitive impairment was positive for patients aged 40–49 years (OR = 1.349 [95% CI: 1.039–1.753] per 10mmHg, P = 0.025) and 50–59 years (OR = 1.185 [95% CI: 1.028–1.366] per 10mmHg, P = 0.019), whereas it tended to be negative for patients aged 60–69 years (OR = 0.878 [95% CI: 0.729–1.058] per 10mmHg, P = 0.171) and ?70 years (OR = 0.927 [95% CI: 0.772–1.113] per 10mmHg, P = 0.416). Results similar to those for SBP were obtained for DBP, MABP and HBP as well. Subsequently, SBP, DBP and MABP were transformed into categorical data (SBP<140mmHg, 140mmHg?SBP<160mmHg, and SBP?160mmHg; DBP<90mmHg, 90mmHg?DBP<100mmHg, and DBP?100mmHg; MABP<100mmHg, 100mmHg?MABP<110mmHg, and MABP?110mmHg), and the stratified multivariate analysis was repeated. This analysis showed that the age-dependent association continued to exist and was especially prominent in the SBP?160 mmHg, DBP?90 mmHg and MABP?110 mmHg groups.


High blood pressure try surely synchronised that have intellectual disability regarding middle-old, however, this confident organization declines that have expanding years. Such efficiency indicated that particular hypertension government suggestions for some age range may be crucial for keeping intellectual energies.
