Chronic Lumbar Pain and Insomnia in College-Aged Students.

Insomnia in college students has a significant impact on academic performance and mental health (e.g., depression). Although the mechanisms underlying insomnia and chronic pain are becoming clearer, only a few studies on college students have examined these factors by their location in the body. The purpose of the present study was to identify the location of chronic pain in the body most associated with insomnia in college students. A web-based survey was used to collect information pertaining to nine questions from 494 university students: sex, age, presence of chronic pain, intensity of chronic pain, location of chronic pain, and duration of chronic pain, as well as scores from the Athens Insomnia Scale (AIS), Pain Catastrophizing Scale, and Hospital Anxiety and Depression Scale. To examine the association between insomnia and the site of chronic pain, stepwise logistic regression analysis was conducted with AIS as the target variable. The results showed a significant positive correlation between chronic pain in the lumbar region and AIS scores. Future longitudinal studies including multiple factors are necessary to clarify the causal relationship between insomnia and chronic lower back pain.

Factors Associated With Psycho-Cognitive Functions in Patients With Persistent Pain After Surgery for Femoral Neck Fracture.

BACKGROUND: The aim of the study was to address issues arising from fracture of the femoral neck in elderly individuals, the prevalence of which continues to increase in Japan. The prevalence is increasing in Japan and there have been many reports on physical functions such as prevention of a fall. However, there have been a few studies that focus on psycho-cognitive functions. We must examine factors in patients with fractured femur necks to develop methods to assist affected patients. The current study aimed to examine factors associated with psycho-cognitive functions after surgery for fractured femoral neck in the Japanese elderly. METHODS: In this study, we examined the relationships among sex, age, fracture site, operative procedure, body mass index, lifestyle, psycho-cognitive functions, and types of pain in 142 patients, performed multiple regression analysis using the mini-mental state examination (MMSE) and the Montgomery-Asberg depression rating scale (MADRS) scores as dependent variables, and created MMSE and MADRS models. RESULTS: Analysis of MMSE and MADRS models identified night pain and the number of family members as factors that affected mental function in a population with persistent pain for 1 week after surgery for fractured femoral neck. In addition, the number of family members was identified in multiple regression analysis models as a factor associated with psycho-cognitive functions. Pain, and night pain in particular, affect psycho-cognitive functions. CONCLUSIONS: We speculated that emotional changes were associated with number of family members. Patients living with family members maintained psycho-cognitive functions better than did those living alone, even when they experienced pain in their daily lives.

[An analysis of fall accidents in ambulance service records of fire department in Japan: investigation of time and location].

PURPOSE: The aim of this study was to examine fall accidents in Japan by analyzing records of ambulance responses. METHOD: The survey period was one year, from January to December, 2007. During this period, a total of 31,002 ambulance responses to fall accidents were recorded by 37 fire departments throughoutiapan. The ambulance responses to fall accidents were analyzed in terms of sex, age, place, time of fall, and degree of injury. RESULTS: The number of ambulance responses per population sample of 1000 people was 1.9 cases among people ranging in age from 20 to 64, 6.3 cases for people ranging in age from 65 to 74 and 15.9 cases for people aged 75 years or over. When excluding males in the 75 year or older group, more falls occurred from December to February than in the other seasons. There were also more falls in December than in any other month. In addition, more falls occurred in houses than at other locations. Roadside locations followed houses regarding the location of falls for males. In addition, public places were the second most common location for females. The degree of injury was higher for females than for males. Females 75 years of age or older sustained 2.8 times more serious injuries than females ranging from 20 to 64 years of age. CONCLUSION: The causes and other characteristics of fall accidents were thus found to vary according to sex and/or age.

[An analysis of fall accidents using Kochi Fire Department ambulance statistics].

PURPOSE: The aim of this study was to examine ambulance usage due to fall accidents in Kochi City. METHOD: The survey period was one year, from January to December, 2005. A total of 967 ambulance responses to fall accidents were recorded by the Kochi Fire Department during this period. Ambulance responses to fall accidents were analyzed in terms of sex, age, time, and place of fall. Adults were defined as subjects between the ages of 18 and 64; elderly adults were defined as being 65 or older. RESULTS: The number of ambulance responses per a population sample of 1000 people was 1.32 cases in adults (men 1.55, women 1.11) and 10.48 cases in elderly adults (men 9.14, women 11.32). The proportion of outdoor falls for adults was 60.8%, for women and 56.8% for men. The respective values for elderly adults were 54.9% and 36.6%. The majority of elderly adult women fell down indoors. More falls occurred in winter (from December to February) than in the other seasons. There were more falls in December than other months. CONCLUSION: Fall incidence varies according to sex, age and season. We can conclude that the causes and places of falls are related to physical activity and season. Fire department ambulance records can be utilized to analyze fall situation in local areas. Such analyses should lead to new approaches to fall prevention measures.
