Effect of diabetes and prediabetes on the development of disability and mortality among middle-aged Japanese adults : A 22-year follow up of NIPPON DATA90.
Aims/introduction:To examine the association between diabetes and prediabetes at baseline, and disability, mortality over a 22-year period among middle-aged Japanese adults.Materials and methods:Participants consisted of 1,788 adults aged 45-64 years at baseline from the cohort study National Integrated Project for Prospective Observation of Non-communicable Disease and its Trends in the Aged 1990 (NIPPON DATA90). Disability, defined as having a decline in activities of daily living (ADL), was assessed by a modified Katz questionnaire at four time points. Disability and death without disability for 22-year follow up were used as outcomes to test the association with a diagnosis of diabetes or prediabetes at baseline, using multinomial logistic regression. Adjusted odds ratios (ORs) were obtained from four models that contained appropriate adjustment factors, such as age, sex, smoking status, drinking status, body mass index and cardiovascular risk factors (hypertension, hypercholesterolemia, triglycerides, low serum high-density lipoprotein), at baseline.Results:In the present study, 334 participants (18.7%) reported at least one disability, and 350 (19.6%) were reported dead without observation of disability during follow up. Adjusting sex and other risk factors, participants with diabetes and prediabetes had a higher risk for disability (OR 1.43, 95% confidence interval [CI] 1.07-1.91 and OR 1.66, 95% CI 1.10-2.50, respectively) and for mortality (OR 1.56, 95% CI 1.16-2.08 and OR 1.77, 95% CI 1.18-2.65, respectively) than individuals with normal glucose tolerance.Conclusions:In middle-aged Japanese adults, individuals with diabetes and prediabetes were more likely to be associated with disability and mortality. Our findings suggest that prediabetes and diabetes in middle-aged adults should be paid more attention, and requires more intervention to prevent disability and mortality in later life

Relationship of Higher-level Functional Capacity With Long-term Mortality in Japanese Older People : NIPPON DATA90
Background:Basic and instrumental activities of daily living (BADL and IADL, respectively) are known predictors of mortality. However, the relationship between higher-level functional capacity (HLFC) and mortality and related sex differences have rarely been investigated.Methods:A prospective population-based cohort study was conducted in 1,824 older residents (≥65 years) with independent BADL from 300 randomly selected areas in Japan from 1995, and the participants were followed up until 2010. Using the Cox proportional hazards model, the relationship between HLFC and mortality risk was investigated, with adjustment for possible confounders. HLFC was assessed using the Tokyo Metropolitan Institute of Gerontology Index of Competence. Baseline data were collected using a questionnaire or by home-visit interviews.Results:During an average 12.2-year follow-up, all-cause death was observed in 836 (45.8%) participants. Impaired HLFC was significantly associated with mortality (hazard ratio [HR] 1.37; 95% confidence interval [CI], 1.13-1.65). Lower social role was significantly associated with higher mortality risk in men (HR 1.38; 95% CI, 1.13-1.68). Lower IADL and intellectual activity were significantly associated with higher mortality risk in women (HR 1.50; 95% CI, 1.15-1.95 and HR 1.46; 95% CI, 1.19-1.79, respectively). The relationship between HLFC and mortality risk showed a similar tendency among cardiovascular diseases, stroke, cancer, and pneumonia.Conclusion:Impaired HLFC was associated with a high risk of all-cause mortality among community-dwelling older people with independent BADL. In particular, social role in men and IADL and intellectual activity in women were associated with long-term mortality risk
Isolated systolic hypertension and 29-year cardiovascular mortality risk in Japanese adults aged 30--49 years.
Objective:The prognostic implication of isolated systolic hypertension (ISH), defined as SBP at least 140 mmHg and DBP less than 90 mmHg, among young-to-middle-aged adults remains controversial. We examined the association of ISH with cardiovascular disease (CVD) risk in adults aged 30-49 years.Methods:In a prospective cohort of representative Japanese general populations from the NIPPON DATA80 (1980-2009), we studied 4776 participants (mean age, 39.4 years; 55.4% women) without clinical CVD or antihypertensive medication. Participants were classified as follows: normal blood pressure (BP) (SBP/DBP, <120/<80 mmHg), high-normal BP (120-129/<80 mmHg), elevated BP (130-139/80-89 mmHg), ISH, isolated diastolic hypertension (IDH) (<140/≥90 mmHg), and systolic--diastolic hypertension (SDH) (≥140/≥90 mmHg).Results:ISH was observed in 389 (8.1%) participants. During the 29-year follow-up, 115 participants died of CVD, 28 of coronary heart disease, and 49 of stroke. Cox proportional hazards models adjusted for demographics and CVD risk factors showed that participants with ISH had higher risk of CVD mortality than those with normal BP [hazard ratio (confidence interval), 4.10 (1.87-9.03)]. The magnitude of CVD mortality risk related to ISH was comparable with that related to IDH [3.38 (1.31-8.72)] and not as great as that related to SDH [5.41 (2.63-11.14)]. We found significant associations of ISH with coronary and stroke mortality. The association of ISH with CVD mortality was consistent across men and women and those aged 30-39 and 40-49 years.Conclusion:ISH among young-to-middle-aged Japanese adults was independently associated with higher risk of CVD mortality later in life
