Association between physical multimorbidity in middle adulthood and mortality
Physical multimorbidity in middle adulthood is associated with an increased risk of all-cause mortality in Japan
Differential Longitudinal Associations Between Domains of Cognitive Function and Physical Function
The results show that distinct domains of cognitive functions have different associations with physical functions. Namely, the aging-associated declines in the tested physical functions are robustly correlated with the declines in Gf, but are only weakly correlated with the declines in Gc. Therefore, Gc measures may be poor proxies for the patient's frailty and should be considered with caution in clinical assessment
Does positive affect predict mortality and morbidity? A 19-year longitudinal study of middle-aged and older Japanese adults
Positive affect contributes to health and longevity. While most research has been conducted in individualistic societies where the experience and expression of positive emotions are highly valued, evidence remains scarce in collectivistic societies that de-emphasize the importance thereof. Employing 19-year longitudinal data of Japanese adults (age range 40–79; N = 2,033), we examined whether positive affect predicted mortality and morbidity. Hea…
Stability and change in well-being among middle-aged and older Japanese
Prior evidence suggests that subjective well-being (SWB) remains relatively stable across adulthood. However, longitudinal evidence is sparse except in Western societies such as North America and Western Europe. We examined age-related changes in SWB (life satisfaction, positive affect, and negative affect) among middle-aged and older Japanese. We applied multilevel growth models to 14-year seven-wave longitudinal data of a dynamic cohort study. …
Protein intake per day and at each daily meal and skeletal muscle mass declines among older community dwellers in Japan
Objective: To examine associations between protein intake per day and at different meals and skeletal muscle mass declines. Design: Two-year prospective cohort study among older community dwellers. Setting: National Institute for Longevity Sciences–Longitudinal Study of Aging (NILS-LSA) in Japan. Participants: Older men ( n 292) and women ( n 363) aged 60–87 years who participated in the baseline (2006–2008) and follow-up studies (2008–2010) of N…
Green tea and coffee intake and risk of cognitive decline in older adults
Objective: To examine the association between green tea and coffee intake and cognitive decline in older adults. Design: A prospective cohort study. The average intake of green tea and coffee in the previous year was assessed through a dietitian interview using a dietary questionnaire. A Mini-Mental State Examination (MMSE) was conducted up to six times biennially. Cognitive decline was screened using the MMSE; its incidence was defined as the fi…
Fish and Meat Intake, Serum Eicosapentaenoic Acid and Docosahexaenoic Acid Levels, and Mortality in Community-Dwelling Japanese Older Persons
The associations between meat/fish consumption, docosahexaenoic acid (DHA)/eicosapentaenoic acid (EPA) intakes, and blood DHA/EPA levels, and mortality in Japan were examined as part of the National Institute for Longevity Sciences-Longitudinal Study of Aging: 520 men and 534 women (60-79 years at baseline) were followed from 1997-2017. Nutritional intakes were assessed using a 3-day dietary record and fasting venous blood samples were collected.…
Positive Effects of Openness on Cognitive Aging in Middle-Aged and Older Adults
The relationship between openness (a psychological trait of curiosity) and a cognitive change was examined in middle-aged and older adults. Participants were 2214 men and women (baseline age range: 40 to 81 years). They were tested up to seven times over approximately 13 years. Openness at the baseline was assessed by the NEO Five-Factor Inventory. Cognitive abilities were assessed at each examination using the Wechsler adult intelligence scale-r…
Does high educational level protect against intellectual decline in older adults
This study examined the relation between educational level and intellectual change in Japanese older adults. Participants (age = 65–79 years, n = 593) comprised the first‐wave participants of the N ational I nstitute for L ongevity S ciences‐ L ongitudinal S tudy of A ging ( NILS‐LSA ). They were followed for 10 years and were tested six times. Educational levels were divided into two groups (low‐educated or high‐educated), and intellectual chang…
