The age-Oriented Dating between Blood circulation pressure and you may Cognitive Disability: A mix-Sectional Investigation in an outlying Area of Xi’an, China

Blood pressure try a convertible chance factor to own cognitive disability, whilst dating ranging from blood pressure levels and you can cognitive handicap is not totally knew. The purpose of this research was to read the the effect off ages to your matchmaking ranging from blood pressure level and cognitive disability.


Blood circulation pressure and you can in the world intellectual setting information is obtained regarding 1799 professionals (age 40–85) whom stayed in a community in the suburbs away from Xi’an, Asia http://datingranking.net/pl/grizzly-recenzja, while in the when you look at the-individual interviews. Intellectual handicap try defined as a small-State of mind Examination (MMSE) rating below the cutoff well worth. The effect of age for the matchmaking anywhere between blood pressure variables [systolic blood circulation pressure (SBP), diastolic hypertension (DBP), suggest arterial blood circulation pressure (MABP), and you may hypertension (HBP, SBP?140 mm Hg and you will/otherwise DBP?90 mm Hg)] and you may cognitive disability are examined by logistic regression designs playing with telecommunications and you will stratified studies. Blood pressure and you will age had been regarded as each other proceeded and categorical investigation.


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.


High blood pressure try certainly correlated that have cognitive disability in the middle-aged, however, which self-confident relationship refuses with expanding many years. This type of show revealed that certain blood circulation pressure management tricks for certain age groups can be critical for maintaining cognitive powers.
