Providing older person individuals with an appropriate intervention at the time of frailty onset is important to prevent the progression of the condition and the need for long-term care. However, the proper timing of starting nutritional and dietary interventions for frail older person subjects has not been fully elucidated. Therefore, in this cross-sectional study, we aimed to clarify the association between frailty and dietary variety among older persons in Japan. We surveyed sex, age, body height, body weight, body mass index, serum albumin level, dietary variety, and nutritional intake indexes in 747 community-dwelling older person individuals who underwent a comprehensive health examination in October 2014. Frailty was determined using the Kihon Checklist (25 questions). Kihon Checklist is widely used to assess frailty in Japan, and their physical, cognitive and social function was evaluated. After excluding those who did not complete the Kihon Checklist and those who required long-term care, frailty status was analyzed in 665 older person individuals. The numbers and percentages of frail, pre-frail and robust older persons were found to be 77 (11.6%), 182 (27.4%) and 406 (61.0%) respectively. Significant differences among robust, pre-frail, and frail subjects were observed in terms of age, serum albumin level, alcohol consumption, smoking, and history of diabetes. Among the nutrition-related indexes, only the dietary variety showed a significant difference. The results of ordinal logistic regression analysis showed a significant association between frailty and sex, age, smoking status, diabetes, and dietary variety score. Dietary variety was significantly associated with the progression of frailty among older persons in the community.
Background. Central sensitization (CS) and psychological factors are associated with pain intensity; however, the mediating role of CS on the relation between psychological factors and pain intensity remains unclear. Objectives. We performed mediation analysis to investigate how CS mediates relation between psychological factors and pain intensity. Methods. Twenty patients with musculoskeletal pain were included in this cross-sectional study. Central sensitization inventory (CSI), one pain intensity-related outcome measure (Short-Form McGill Pain Questionnaire 2 (SFMPQ2)), and three psychological outcome measures (Hospital Anxiety and Depression Scale (HADS), Pain Catastrophizing Scale-4 (PCS), and Tampa Scale for Kinesiophobia-11 (TSK)) of all participants were assessed. The mediation analysis with a bootstrap sampling procedure was used to assess the indirect effects. The level of significance was set at 5%. Results. Mediation analysis showed that the HADS-anxiety, HADS-depression, and PCS had significant indirect effects on the pain ratings of CSI. Additionally, the direct effect was significant only for PCS. Conclusions. The relationship among anxiety symptoms, depression symptoms, and pain intensity was completely mediated by CS. Furthermore, the relationship between catastrophic thinking and pain intensity was partially mediated by CS. Our findings suggest that CS mediates relation between psychological factors and pain intensity, and CS-focused intervention may be important.
This study aimed to perform cluster analysis in patients with chronic pain to extract groups with similar circadian rhythms and compare neuropathic pain and psychological factors among these groups to identify differences in pain-related outcomes. A total of 63 community-dwellers with pain lasting at least 3 months and Numerical Rating Scale scores of ≥2 were recruited from 3 medical institutions. Their pain circadian rhythms were evaluated over 7 days by measuring pain intensity at 6-time points per day using a 10-cm visual analog scale. Cluster analysis was performed using 6 variables with standardized visual analog scale values at 6-time points for individual participants to extract groups with similar pain circadian rhythms. The results of the Neuropathic Pain Symptom Inventory and psychological evaluations in each group were compared using the Kruskal–Wallis test. The results revealed 3 clusters with different circadian rhythms of pain. The total and evoked pain subscale Neuropathic Pain Symptom Inventory scores differed among the 3 clusters. The results suggest that a thorough understanding of circadian pain rhythms in chronic pain patients may facilitate the performance of activities of daily living and physical exercise from the perspective of pain management.
