The age-Based Relationship ranging from Blood pressure levels and you may Intellectual Handicap: A mix-Sectional Analysis within the a rural Section of Xi’an, Asia

Blood circulation pressure is a convertible chance grounds getting cognitive disability, whilst relationship anywhere between blood pressure level and you can intellectual handicap is not completely knew. The goal of this research was to check out the the effect off ages with the dating ranging from blood pressure level and you can intellectual handicap.


Blood pressure and you may around the globe intellectual means information is actually collected out-of 1799 participants (years forty–85) which stayed in a village on the suburbs off Xi’an, China, during into the-individual interview. Intellectual impairment is actually defined as a micro-State of mind Examination (MMSE) score lower than the latest cutoff really worth. The outcome of age to your matchmaking ranging from blood pressure levels details [systolic hypertension (SBP), diastolic blood pressure level (DBP), mean arterial hypertension (MABP), and you will high blood pressure (HBP, SBP?140 mm Hg and/or DBP?90 mm Hg)] and cognitive disability are analyzed because of the logistic regression designs using interaction and you will stratified investigation. Blood pressure levels and you may decades was basically considered one another continued and categorical study.


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 = telegraph dating seznamovací aplikace 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.


Raised blood pressure are certainly synchronised with intellectual impairment on the middle-aged, but that it positive connection refuses that have broadening decades. These types of abilities indicated that particular hypertension administration tricks for individuals age range is generally crucial for maintaining intellectual energies.
