Background: The aim of this study was to clarify pain, quality of life and activity in the aged evacuees living in temporary housing after the Great East Japan Earthquake on 11 March 2011.Methods: The study was a cross-sectional study performed in Minamisoma City, Fukushima Prefecture 1 year and 6 months after the disaster. Inclusion criteria were the ability to walk independently and consent to answer questionnaires. Seventy-one evacuees who met the inclusion criteria were included in this study. There were 16 men and 55 women with a mean age of 75.9 years. Sixty evacuees were surveyed when they gathered at the assembly hall in the temporary housing (Assembled group) and 11 evacuees were surveyed through individual visits to their residences (Individual group). Evacuees in the Individual group agreed to participate in this study, but refused to visit the assembly hall to engage in exercise and recreation. Pain, quality of life (QOL) and level of activity were assessed with the Numeric Rating Scale (NRS), the MOS Short-Form 36 item Health Survey (SF-36) and a pedometer, respectively. Student's t-test, Mann-Whitney U test, and Fisher's exact test were used for statistical analysis.Results: Forty-four (62.0 %) residents had chronic pain with a mean NRS of 2.74. Twenty-one (29.6 %) of these residents had relatively severe pain rated 5 or above on the NRS. QOL was significantly lower for the subscales of "physical functioning," "role physical", "general health", "social functioning", "role emotional" and "mental health", when compared with the national standard values. Values were also visibly lower for "physical component summary" in the summary score. On comparing the Assembled group and the Individual group, "physical function", "role physical", "social functioning" and "physical component summary" were found to be significantly lower in the Individual group. The mean daily number of steps was 1,892 in the Individual group and 4,579 in the Assembled group. The Individual group thus significantly took less mean daily number of steps compared with the Assembled group.Conclusions: This study quantified the state of pain, QOL and activity of aged evacuees living in temporary housing after the Great East Japan Earthquake. The evacuees frequently had chronic pain and lower physical and mental QOL scores compared to the national standard values. [ABSTRACT FROM AUTHOR]

Background: no study has examined the longitudinal association between hand-grip strength and mental health, such as depressive symptoms. Objective: we investigated the relationship between baseline hand-grip strength and the risk of depressive symptoms. Design: a prospective cohort study. Low hand-grip strength associates with depression Setting and Subjects: a prospective cohort study with a 1-year follow-up was conducted using 4,314 subjects from community-dwelling individuals aged 40--79 years in two Japanese municipalities, based on the Locomotive Syndrome and Health Outcomes in Aizu Cohort Study (LOHAS, 2008-10). Methods: we assessed baseline hand-grip strength standardised using national representative data classified by age and gender, and depressive symptoms at baseline and after the follow-up using the five-item version of the Mental Health Inventory (MHI-5). Results: the 4,314 subjects had a mean age of 66.3 years, 58.5% were women, and mean unadjusted hand-grip strength was 29.8 kg. Multivariable random-effect logistic regression analysis revealed that subjects with lower hand-grip strength (per 1SD decrease) had higher odds of having depressive symptoms at baseline [adjusted odds ratio (AOR) 1.15, 95% confidence interval (CI) 1.06--1.24; P = 0.001]. Further, lower hand-grip strength (per 1SD decrease) was associated with the longitudinal development of depressive symptoms after 1 year (AOR 1.13, 95% CI 1.01-1.27; P= 0.036). Conclusions: using a large population-based sample, our results suggest that lower hand-grip strength, standardised using age and gender, is both cross-sectionally and longitudinally associated with depressive symptoms.

Abstract Background  The Japanese Orthopaedic Association decided to revise the JOA score for low back pain and to develop a new outcome measure. In February 2002, the first survey was performed with a preliminary questionnaire consisting of 60 evaluation items. Based on findings of that survey, 25 items were selected for a draft of the JOA Back Pain Evaluation Questionnaire (JOABPEQ). The second survey was performed to confirm the reliability of the draft questionnaire. This article further evaluates the validity of this questionnaire and establishes a measurement scale. Methods  The subjects of this study consisted of 355 patients with low back disorders of any type (201 men, 154 women; mean age 50.7 years). Each patient was asked to fill in a self-administered questionnaire. Superficial validity was checked in terms of the completion rate for filling out the entire questionnaire. Factor analysis was then performed to evaluate the validity of the questionnaire and establish a measurement scale. Results  As a result of the factor analysis, 25 items were categorized into five factors. The factors were named based on the commonality of the items: social function, mental health, lumbar function, walking ability, and low back pain. To establish a measurement scale for each factor, we determined the coefficient for each item so the difference between the maximum factor scores and minimum factor scores was approximately 100. We adjusted the formula so the maximum for each factor score was 100 and the minimum was 0. Conclusions  We confirmed the validity of the JOA Back Pain Evaluation Questionnaire and est ablished a measurement scale. [ABSTRACT FROM AUTHOR]
