Objective light-intensity physical activity associations with rated health in older adults.

Abstract: The extent to which light-intensity physical activity contributes to health in older adults is not well known. The authors examined associations between physical activity across the intensity spectrum (sedentary to vigorous) and health and well-being variables in older adults. Two 7-day assessments of accelerometry from 2005 to 2007 were collected 6 months apart in the observational Senior Neighborhood Quality of Life Study of adults aged >65 years in Baltimore, Maryland, and Seattle, Washington. Self-reported health and psychosocial variables (e.g., lower-extremity function, body weight, rated stress) were also collected. Physical activity based on existing accelerometer thresholds for moderate/vigorous, high-light, low-light, and sedentary categories were examined as correlates of physical health and psychosocial well-being in mixed-effects regression models. Participants (N = 862) were 75.4 (standard deviation, 6.8) years of age, 56% female, 71% white, and 58% overweight/obese. After adjustment for study covariates and time spent in moderate/vigorous physical activity and sedentary behavior, low-light and high-light physical activity were positively related to physical health (all P < 0.0001) and well-being (all P < 0.001). Additionally, replacing 30 minutes/day of sedentary time with equal amounts of low-light or high-light physical activity was associated with better physical health (all P < 0.0001). Objectively measured light-intensity physical activity is associated with physical health and well-being variables in older adults.

Neuropsychiatric aspects of Huntington's disease

Abstract: OBJECTIVE Neuropsychiatric symptoms are common in Huntington9s disease and have been considered its presenting manifestation. Research characterising these symptoms in Huntington9s disease is variable, however, encumbered by limitations within and across studies. Gaining a better understanding of neuropsychiatric symptoms is essential, as these symptoms have implications for disease management, prognosis, and quality of life for patients and caregivers. METHOD Fifty two patients with Huntington9s disease were administered standardised measures of cognition, psychiatric symptoms, and motor abnormalities. Patient caregivers were administered the neuropsychiatric inventory. RESULTS Ninety eight per cent of the patients exhibited neuropsychiatric symptoms, the most prevalent being dysphoria, agitation, irritability, apathy, and anxiety. Symptoms ranged from mild to severe and were unrelated to dementia and chorea. CONCLUSIONS Neuropsychiatric symptoms are prevalent in Huntington9s disease and are relatively independent of cognitive and motor aspects of the disease. Hypothesised links between neuropsychiatric symptoms of Huntington9s disease and frontal-striatal circuitry were explored. Findings indicate that dimensional measures of neuropsychiatric symptoms are essential to capture the full range of pathology in Huntington9s disease and are vital to include in a comprehensive assessment of the disease.
