Alcohol drinking patterns have a positive association with cognitive function among older people: a cross-sectional study.

Background: The relationship between moderate alcohol drinking or other alcohol drinking patterns such as frequency, beverage type, and situation of drinking and cognitive function is not sufficiently clear in older people. The purpose of this study was to investigate the association between alcohol drinking patterns and cognitive function in community-dwelling Japanese people aged 75 and over.

Methods: This study was a cross-sectional design based on a prospective cohort study called the SONIC study.

The Association Between Longevity-Associated FOXO3 Allele and Heart Disease in Septuagenarians and Octogenarians: The SONIC Study.

The G allele of FOXO3 gene (single-nucleotide polymorphism; rs2802292) is strongly associated with human longevity. However, knowledge of the effect of FOXO3 in older populations, men or women, with heart disease is limited. This cross-sectional study in Japan included 1836 older adults in the 70- and 80-year-old groups.

Association between physical function and onset of coronary heart disease in a cohort of community-dwelling older populations: The SONIC study.

Background: Physical function is a strong predictor of the adverse outcomes of cardiovascular disease in older populations. However, studies of healthy older people on the prevention of coronary heart disease (CHD) are very limited.

Objectives: We prospectively examined the association of walking speed and handgrip strength with CHD in the community-dwelling older populations.

Association between heart diseases, social factors and physical frailty in community-dwelling older populations: The septuagenarians, octogenarians, nonagenarians investigation with centenarians study.

Aim: Heart diseases and social factors are associated with physical frailty, but there are few studies of older people living in the community. Consequently, the aim of this study was to examine the association between heart diseases, social factors and physical frailty in community-dwelling older populations including the oldest-old people.

Methods: The cross-sectional study included 1882 participants of community-dwelling older and oldest-old people.

Association between physical function and long-term care in community-dwelling older and oldest people: the SONIC study.

Background: Preventing the need for long-term care (LTC) by identifying physical function risk factors are important to decrease the LTC burden. The objective of this study was to investigate whether grip strength and/or walking speed, which are components of the frailty definition, are associated with LTC in community-dwelling older and oldest people.

Methods: The participants were 1098 community-dwelling older and oldest people who had not received LTC at the baseline.

The importance of stroke as a risk factor of cognitive decline in community dwelling older and oldest peoples: the SONIC study.

Background: Cognitive impairment is a major health concern among older and oldest people. Moreover, stroke is a relevant contributor for cognitive decline and development of dementia. The study of cognitive decline focused on stroke as the important risk factor by recruiting older and oldest is still lagging behind.
