The age-Built Relationships anywhere between Blood pressure level and you can Intellectual Handicap: A cross-Sectional Data inside the an outlying Area of Xi’an, Asia

Blood circulation pressure are a modifiable chance basis for cognitive impairment, as the relationships ranging from hypertension and you can intellectual impairment is not totally knew. The reason for this study would be to browse the the end result away from many years towards relationship anywhere between blood pressure levels and cognitive handicap.


Blood pressure level and you will all compatible partners reddit over the world intellectual form pointers try accumulated off 1799 people (age 40–85) whom lived-in a community from the suburbs away from Xi’an, China, during into the-people interview. Intellectual impairment try recognized as a mini-State of mind Examination (MMSE) score lower than the fresh new cutoff worth. The effect of age to your matchmaking anywhere between blood pressure variables [systolic hypertension (SBP), diastolic blood pressure (DBP), mean arterial blood circulation pressure (MABP), and you will high blood pressure (HBP, SBP?140 mm Hg and/otherwise DBP?90 mm Hg)] and cognitive handicap is assessed of the logistic regression activities using communication and you can stratified study. Blood pressure and you may many years have been thought to be one another continued and you may categorical analysis.

Overall performance

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.


Hypertension is absolutely synchronised having intellectual impairment about middle-aged, however, that it positive association declines with increasing years. These types of results indicated that certain blood circulation pressure management strategies for certain a long time is crucial for maintaining cognitive energies.
