Blood pressure levels is a modifiable exposure grounds having intellectual handicap, whilst the relationship ranging from blood pressure level and you will cognitive disability is not completely know. The goal of this study were to check out the the result away from ages with the matchmaking anywhere between blood pressure levels and you will cognitive impairment.
Methods
Blood pressure levels and you will globally intellectual setting suggestions is actually accumulated out-of 1799 participants (ages 40–85) just who lived-in a town throughout the suburbs from Xi’an, China, throughout when you look at the-person interviews. Cognitive handicap try defined as a mini-State of mind Examination (MMSE) score lower than the new cutoff worth. The outcome old into relationships ranging from blood pressure variables [systolic blood pressure (SBP), diastolic blood circulation pressure (DBP), suggest arterial hypertension (MABP), and you will high blood pressure (HBP, SBP?140 mm Hg and you can/otherwise DBP?90 mm Hg)] and you will cognitive disability try reviewed by logistic regression models using correspondence and you will stratified study. Blood pressure levels and you may decades was in fact considered both continuing and you may categorical data.
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 charmdate bezpÅ‚atna aplikacja. 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
Hypertension is surely correlated that have intellectual disability regarding the middle-aged, but that it positive organization declines that have growing decades. Such efficiency revealed that certain blood pressure level management suggestions for certain age groups are critical for maintaining intellectual vitality.
