Blood circulation pressure are a modifiable risk foundation to possess cognitive impairment, as the relationships anywhere between hypertension and you may intellectual impairment isn’t fully understood. The reason for this study was to have a look at the outcome out-of decades to your relationships anywhere between hypertension and you will intellectual handicap.

Steps

Blood circulation pressure and you may all over the world intellectual means suggestions is actually accumulated out of 1799 members (decades 40–85) which lived in a village from the suburbs out-of Xi’an, Asia, during inside-individual interview. Cognitive handicap are defined as a micro-State of mind Test (MMSE) score below brand new cutoff value. The end result old towards the dating between hypertension parameters [systolic blood pressure level (SBP), diastolic blood pressure (DBP), mean arterial blood circulation pressure (MABP), and you will raised blood pressure (HBP, SBP?140 mm Hg and/or DBP?90 mm Hg)] and you may cognitive handicap are examined from the logistic regression designs having fun with correspondence and you can stratified investigation. Hypertension and you will many years was indeed considered to be one another proceeded and you will categorical investigation.

Efficiency

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 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.

Findings

High blood pressure levels try absolutely correlated which have cognitive impairment from the middle-old, but that it positive organization declines that have expanding age. This type of results indicated that particular hypertension government tips for some a long time could be critical for keeping cognitive vitality.
