A total of 4,505 middle-aged and older people with stage 1-4 CKD who were free from cardiovascular events (mean age: 67.2 years) were followed up for an average of 10.3±2.4 years. We investigated the association of serum cholinesterase levels with all-cause mortality using multivariable regression analyses and restricted cubic spline analyses.
In middle-aged and older people with stage 1-4 CKD, the serum cholinesterase level had significant value in predicting all-cause mortality and added prognostic information to conventional risk assessments. -

This study aimed to clarify the association between PA changes and the risk of all-cause mortality among survivors of the Great East Japan Earthquake.
At two time points from 2011 to 2012, 2138 men and 3683 women responded to a question about walking time. The cut-off value was set at 30 min, and PA changes were evaluated using responses regarding walking time over 2 years. Participants were classified into four groups according to PA changes: high stable, increasing, decreasing and low stable. Using a Cox regression model, multivariate-adjusted HRs and 95% CIs for all-cause mortality, according to PA changes, were calculated after adjusting for age, area, smoking status, drinking status, grip strength, psychological distress, obesity, hypertension, diabetes, dyslipidaemia, residential status and current job status.
During the 5-year follow-up, 241 deaths occurred. Compared with that of the high stable group, the decreasing group had a higher risk of all-cause mortality; multivariate-adjusted HRs were 2.40 and 2.43 for men and women, respectively. Among women, the low stable group also had a higher risk of all-cause mortality compared with that of the high stable group.
Our findings indicate the importance of assessing PA and creating an environment to allow its maintenance as early as possible after large-scale natural disasters. -

Whether the association between metabolic syndrome (MetS) and functional disability differs depending on sex or age
remains unknown. To determine the association between MetS and functional disability in older people separately by sex and age groups. A total of 11 083 participants (4407 men and 6676 women) aged 65 years or over without functional disability
were enrolled. MetS was defined according to the revised NCEP ATP III guidelines. Functional disability was defined by a new certification in the long-term care insurance in Japan. Cox proportional hazards models were used to assess the risk of functional disability with adjustment for possible confounding factors. Over the mean observation period of 10.5 years, 1282 men and 2162 women experienced functional disability. For those aged 65 to 74 years, HRs (95% CIs) for functional disability
in the MetS group were 1.33 (1.07-1.66) in men and 1.15 (1.000-1.32) in women. For those aged 75 years or older, there was no significant association in men or women. In subjects with a severe care need level, there was a marginal significant association in men aged 65 to 74 years. Among the MetS components that independently increased the risk of functional disability were glucose intolerance and elevated blood pressure (men and women aged 65-74 years), obesity (women aged 65-74 years), and glucose intolerance (women aged 75 years or older). MetS contributed to an increase in a high risk of future
functional disability among individuals aged 65 to 74 years. In this age group, improvement of lifestyle, health promotion and interventions for MetS from middle age may prevent future functional disability. -

We analyzed data from a longitudinal study of 10 375 community-dwelling older Japanese adults (≥65 years) who were not LTCI needs certified at baseline and joined the study from 2002 to 2005. Weight change (percentage) was calculated by subtracting participants' weight in the previous year from that measured during a physical examination at study commencement. The five weight-change categories ranged from sizable weight loss (≤ -8.0%) to sizable weight gain (≥ +8.0%). Disability was defined according to LTCI certifications at follow-up. Hazard ratios (HRs) and 95% confidence intervals were calculated for new-onset disability using a Cox proportional hazards model that fitted the proportional subdistribution hazards regression model with weights for competing risks of death.

Of the 71 hospitals with 9,992 beds in the Iwate Prefecture in 2018, 50 hospitals with 8,316 beds participated in the DPC system. The proportion of registered cases from participating hospitals was 95.2% (44,779/47,018) for all stroke types (95.6% men and 94.9% women), 94.3% for cerebral infarction, 97.0% for intracerebral hemorrhage, and 98.7% for subarachnoid hemorrhage. Attending doctors and researchers registered 486 and 41 CVD cases from the core and noncore hospitals, respectively, whereas 455 and 46 CVD cases were extracted from the DPC data of these hospitals, respectively. This yielded 86.6% sensitivity, 99.3% specificity, 92.5% positive predictive value, and 98.7% negative predictive value for the core hospital; these values were 92.7%, 98.6%, 82.6%, and 99.5%, respectively, for the noncore hospital.
