“…1 There is growing evidence suggesting that not only anthropometric factors, hypertension, 2 diabetes, 3 obesity, 4 and physical activity 5 but also sleep duration 6,7,8 are implicated in decreased bone mineral density (BMD) in elderly. The association between sleep duration and osteoporosis has been recently studied with conflicting results, 9,10 with some studies stressing the independent risk of short sleep for OS and others reporting an independent risk in long sleepers.…”

Study Objectives: Clinical and epidemiological studies suggest a relation between bone mineral density (BMD) and self-assessment of sleep with an effect on bone formation and osteoporosis (OS) risk in short and long sleepers. This study explores this association in a large sample of older subjects. Methods: We examined 500 participants without insomnia complaints aged 65.7 ± 0.8 y. Each participant had a full evaluation including anthropometric measurement, clinical examination and measurements of BMD at the lumbar spine and femoral sites by dual-energy X-ray absorptiometry. The daily energy expenditure (DEE) was measured by the Population Physical Activity Questionnaire. Sleep duration and quality were evaluated by the Pittsburgh Sleep Quality Index. The subjects were stratified into three groups according to sleep duration, i.e., short (< 6 h), normal (6-8 h), and long (≥ 8 h) sleepers. Results: Osteopenia was found in 40% of the subjects at the femoral level and 43% at the vertebral level. The prevalence of OS was lower both at femoral (8%) and vertebral (12%) levels. Short, normal, and long sleepers accounted for 29%, 40%, and 31% of subjects, respectively. After adjustments for metabolic, anthropometric, and DEE, multinomial logistic regression analysis indicated that long sleepers were more likely to have femoral neck OS with a slight effect of DEE at vertebral spine. Conclusions: In a sample of older subjects, self-reported long sleep was the best predictor of OS risk at the femoral level. This finding suggests an association between OS and self-reported sleep duration in older subjects.

“…Furthermore, the chosen method was logistically preferable to the use of interview-based assessments, due to the large number of participants [40]. The use of accelerometers to objectively measure physical activity allowed data collection for only 1 week, although this approach may be preferable to the assessment of self-recalled physical activity, considering the effects of recall bias [16]. Although we had access to a large number of covariates, there is likely residual confounding in the associations found.…”

“…At the end of the testing session, each participant was asked to wear a triaxial accelerometer (GT3X+; ActiGraph, Pensacola, FL, USA) for seven consecutive days, as described previously [16]. When participants returned with the accelerometers, the data were downloaded and wear time was validated using the ActiLife software (version 6.11.2; ActiGraph).…”

Summary In the present population-based study including 70-year-old men and women, total dairy product intake was associated with a weak positive association with tibia trabecular and cortical cross-sectional areas. Purpose Milk consumption has recently been suggested to increase fracture risk. Therefore, we aimed to investigate associations between dairy product consumption and peripheral bone properties. Furthermore, we explored whether consumption of milk and fermented dairy products affected bone properties differently. Methods The Healthy Aging Initiative is a population-based, cross-sectional study investigating the health of 70-year-old men and women. Out of the 2904 individuals who met the inclusion criteria, data on self-reported daily dairy product consumption (dl/ day), peripheral quantitative computed tomography (pQCT) examinations at the 4 and 66% scan sites of the tibia and radius, and dual-energy X-ray absorptiometry (DXA) scans were collected from 2040 participants. Associations between dairy product consumption and bone properties were examined using multiple linear regression models adjusted for sex, muscle area, meal size, dietary protein proportion, current smoking status, and objectively measured physical activity. Results Total dairy product intake was associated with larger trabecular (2.296 (95% CI, 0.552-4.039) mm 2 , per dl/day increase, p = 0.01) and cortical cross-sectional areas (CSAs) in the tibia (1.757 (95% CI, 0.683-2.830 mm 2 , p = 0.001) as measured by pQCT and higher areal bone mineral density (aBMD) of the radius (3.231 (95% CI, 0.764-5.698) mg/cm 2 , p = 0.01) as measured by DXA. No other measurement in the tibia, radius, femoral neck, or lower spine was associated significantly with dairy product intake. Bone properties did not differ according to the type of dairy product consumed. Conclusion No evidence of a negative association between dairy product consumption and bone health was found. Furthermore, total dairy product consumption was associated with increased CSAs in the tibia, regardless of dairy product type. Collectively, our findings indicate the existence of a weak but significant positive association between dairy product consumption bone properties in older adults.

“…Bone is a biomechanical tissue that adapts its structure to withstand varying forces stemming from muscle activity and gravity 29 . The relationship between physical activity, objectively measured by triaxial accelerometers, and BMD has been described in both healthy older adults 30 and in COPD patients 31 . In healthy older adults, a positive association was found between moderate to vigorous physical activity and femoral neck BDM 30 .…”

In healthy older adults, a positive association was found between moderate to vigorous physical activity and femoral neck BDM 30 .

Objective: To investigate whether there is a relationship between nutritional status and limitations in activities of daily living in patients with chronic obstructive pulmonary disease. Methods: A cross sectional study was conducted from July to December 2011 in Santa Catarina. Seventeen chronic obstructive pulmonary disease patients [age (years) = 67±8; forced expiratory volume in one second (% of the predicted value) = 38.6±16.1; body mass index (kg/m2) = 24.7±5.4] underwent the assessments: pulmonary function (spirometry); functional status (London Chest Activity of Daily Living scale, physical activities in daily life, and Glittre ADL-Test; nutritional status (anthropometry and dual-energy X-Ray absorptiometry). Results: The total score of the London Chest Activity of Daily Living scale correlated with fat-free mass (r=-0.50; p=0.04) and lean mass (r=-0.50; p=0.04). The lying time in physical activities in daily life correlated with bone mineral content (r=-0.50; p=0.04). Nutricional status was not correlated with time spent on Glittre ADL-test. Conclusion: Variables that reflect muscle mass depletion are related to variables of self-reported limitation in activities of daily living. Bone mineral content is correlated with time patients spend lying, reflecting the impact of inactive postures on the nutritional status of these patients.
