Blood pressure is a modifiable risk grounds to own intellectual disability, as the dating anywhere between blood pressure levels and you can cognitive handicap isn’t completely know. The goal of this research was to read the the effect away from decades on relationships between blood pressure levels and you will cognitive disability.

Tips

Blood circulation pressure and you may around the world cognitive means suggestions was collected away from 1799 users (many years forty–85) just who lived-in a village in the suburbs regarding Xi’an, Asia, during the in-individual interviews. Intellectual impairment is recognized as a mini-Mental state Test (MMSE) rating below new cutoff worthy of. The outcome of age with the relationship ranging from blood pressure level variables [systolic blood pressure level (SBP), diastolic blood pressure level (DBP), indicate arterial hypertension (MABP), and you will elevated blood pressure (HBP, SBP?140 mm Hg and you can/or DBP?90 mm Hg)] and you will intellectual impairment is reviewed by the logistic regression activities using telecommunications and stratified investigation. Blood pressure level and ages was basically considered to be one another continuous and you may categorical analysis.

Abilities

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.

Conclusions

Elevated blood pressure is absolutely correlated with cognitive handicap on the middle-old, but which self-confident association declines which have growing many years. This type of overall performance revealed that particular blood pressure management suggestions for individuals age range may be critical for maintaining intellectual vitality.
