Age-Mainly based Dating ranging from Hypertension and you will Intellectual Disability: A mix-Sectional Study during the a rural Part of Xi’an, Asia

Blood pressure is a modifiable risk factor to possess intellectual impairment, although the relationships between blood pressure level and you can intellectual impairment isn’t completely understood. The objective of this study were to look at the the effect out of decades into relationships ranging from blood pressure levels and you will intellectual disability.

Strategies

Blood pressure and global cognitive means pointers was built-up out-of 1799 users (ages 40–85) which lived in a village regarding suburbs out of Xi’an, Asia, during in the-people interviews. Cognitive impairment try defined as a micro-State of mind Examination (MMSE) score below brand new cutoff value. The result old toward relationship ranging from blood pressure level variables [systolic hypertension (SBP), diastolic blood pressure (DBP), imply arterial blood circulation pressure (MABP), and you can elevated blood pressure (HBP, SBP?140 mm Hg and/or DBP?90 mm Hg)] and you can intellectual impairment are examined of the logistic regression patterns having fun with correspondence and stratified research. Blood pressure level and you can age was in fact thought to be one another continued and you may categorical study.

Results

A total of 231 participants were diagnosed as having cognitive impairment based on our criteria. Interaction analysis for the total population together2night seznamovací web 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 is undoubtedly correlated which have cognitive impairment from the middle-old, but this positive relationship declines that have increasing age. Such abilities showed that certain blood pressure management approaches for various age range tends to be crucial for keeping intellectual energies.
