The purpose of this study was to demonstrate the potential alterations in structural network properties related to physical activity (PA) in healthy elderly. We recruited 76 elderly individuals with normal cognition from Samsung Medical Center in Seoul, Korea. All participants underwent the Cambridge Neuropsychological Test Automated Battery and 3.0T brain magnetic resonance imaging (MRI). Participants were subdivided into quartiles according to the International Physical Activity Questionnaire scores, which represents the amount of PA. Through graph theory based analyses, we compared global and local network topologies according to PA quartile. The higher PA group demonstrated better performance in speed processing compared to the lower PA group. Regional nodal strength also significantly increased in the higher PA group, which involved the bilateral middle frontal, bilateral inferior parietal, right medial orbitofrontal, right superior, and middle temporal gyri. These results were further replicated when the highest and the lowest quartile groups were compared in terms of regional nodal strengths and local efficiency. Our findings that the regional nodal strengths associated with the attentional network were increased in the higher PA group suggest the preventive effects of PA on age-related cognitive decline, especially in attention.

“…Its abbreviated version, the WHOQOL-BREF, contains 26 items and is used for epidemiological surveys and clinical trials (WHOQOL Group, 1998a). Psychometric studies support the WHOQOL-BREF’s validity for general populations (Saxena et al, 2001; Skevington et al, 2004; WHOQOL Group, 1998a) and in many countries (Min et al, 2002; Noerholm et al, 2004; Xia et al, 2012; Yao et al, 2002). However, some international studies failed to replicate the original item structure (Moreno et al, 2006; Yao et al, 2008).…”

This study investigated the psychometric properties of the Japanese version of the WHOQOL-BREF among 10,693 community-based married Japanese men and women (4376 couples) who were either expecting or raising a child. Analyses of item-response distributions, internal consistency, criterion validity, and discriminant validity indicated that the scale had acceptable reliability and performed well in preliminary tests of validity. Furthermore, dyadic confirmatory factor analysis revealed that the theoretical factor structure was valid and similar across partners, suggesting that men and women define and value quality of life in a similar way.

Objective: To investigate influences of personality traits on quality of life (QOL) over the first 3 months after stroke. Methods: Participants were interviewed 2 weeks after stroke with a follow-up after 3 months, with QOL (WHOQOL-BREF) measured on both occasions. Personality traits were ascertained at the 3-month examination using the Big Five Inventory, quantifying five personality traits: extraversion, agreeableness, conscientiousness, neuroticism and openness. Influences of personality traits on QOL at the 2 examinations were investigated using repeated-measure analysis of variance (ANOVA) with adjustments for age, gender, number of years in education, use of antidepressants, stroke severity and physical disability. Results: In the 151 patients present at both examinations, neuroticism resulted in lower overall QOL levels on all 4 WHOQOL-BREF domains, and extraversion, agreeableness and conscientiousness influenced some, but not all, QOL domains. The openness trait had no influence on overall QOL levels but showed significant group-by-time interactions on psychological and environment QOL domains. Conclusions: QOL over the 3-month period after stroke was influenced by several personality traits. The neuroticism trait influenced overall QOL levels but not trajectories, while the opposite was true for the openness trait.
