Lifestyle-related signs of locomotive syndrome in the general Japanese population: A cross-sectional study.

BACKGROUND: This study aimed to estimate the prevalence of locomotive syndrome (LS) risk in age groups using the LS risk test proposed by the Japanese Orthopaedic Association. Based on this, this study identified the lifestyle-related signs that lead to LS, by clarifying the association between LS risk and lifestyle factors. METHODS: A total of 728 individuals aged 20-91 years who were without specific mobility disorders were evaluated. Participants were asked to perform the LS risk test and complete a self-administered original questionnaire survey for this study. The Mann-Whitney U test was used to examine the relationships of sex and age with LS. The prevalence of LS by sex and age was compared using the Chi-squared test or Student's t-test, as appropriate. The Mantel-Haenszel test was used to examine the relationship of each component of the lifestyle factors. RESULTS: Overall, 36.4% of males and 49.1% of females were classified into the LS group; the prevalence of LS was significantly higher in females than males (p < .001). The prevalence of LS tended to increase with age in both males and females (p < .05). As for health condition, pain in the locomotive organs, knees, back, and hip joints was significantly associated with LS (p < .05). Of the lifestyle-related diseases, only hypertension (p < .05) was significantly associated with LS, and drug treatment was significantly associated with LS (p < .05). As for lifestyle, anxiety about physical fitness, self-assessed poor health, irregular dietary habits, and lack of exercise were also associated with LS (p < .05). CONCLUSIONS: Interventions to prevent LS are important during its early stages, especially for females, and lifestyle-related signs of LS, such as pain in the locomotive organs, lifestyle-related disease, drug treatment, and a lower subjective evaluation of health must not be overlooked.

Relationship between social capital and happiness in a Japanese community: A cross-sectional study.

The influence of social capital on happiness is attracting attention around the world. Many studies that investigated the relationship between social capital and happiness suggest that happiness correlates to a positive social environment. The aim of this study was to examine the relationship between social capital and happiness in a community with the lowest National Health Insurance expenditures in Miyazaki Prefecture (Japan). This cross-sectional study targeted 2730 residents in the community aged 40-75 years who were covered by National Health Insurance in 2015. A self-administered questionnaire consisting of questions focusing on demographic characteristics, happiness, and social capital was sent to the residents, and 1106 of them (40.5%) returned the questionnaires by the deadline. The analysis of responses indicated a positive relationship between social capital and happiness with regard to all three factors of social capital (trust, connections and interaction, and social participation). Evaluating the relationship between social capital and health in terms of happiness is important to creating a lively society in which citizens support one another, in addition to promoting physical and mental well-being.
