Blood pressure is actually a modifiable chance foundation for cognitive impairment, whilst the relationships anywhere between blood pressure level and you will intellectual disability isn’t fully understood. The objective of this research were to look at the the outcome off age into relationship ranging from hypertension and you can intellectual disability.
Measures
Blood pressure level and you can around the globe cognitive means pointers try gathered out-of 1799 participants (age 40–85) which stayed in a community regarding suburbs away from Xi’an, China, through the in-person interview. Cognitive disability is defined as a small-State of mind Test (MMSE) score less than the new cutoff worth. The effect old toward dating ranging from hypertension details [systolic blood pressure level (SBP), diastolic hypertension (DBP), imply arterial hypertension (MABP), and you can high blood pressure (HBP, SBP?140 mm Hg and you will/or DBP?ninety mm Hg)] and you will intellectual handicap is examined of the logistic regression patterns using correspondence and you can stratified research. Hypertension and age was basically thought to be both carried on and categorical research.
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.
Results
High blood pressure levels was absolutely correlated with intellectual handicap in the middle-old, however, so it confident association refuses with broadening ages. These types of overall performance revealed that particular blood circulation pressure administration methods for individuals age groups tends to be critical for keeping intellectual vitality.
