Associations between markers of glucose metabolism and bone measures among diabetic and non-diabetic adults.

Purpose: To investigate the relationships between bone measures, vitamin D status and markers of glucose metabolism among diabetic and non-diabetic adults.

Methods: Cross sectional study with 298 adults (mean age 57.5 years, SD = 14.

Higher Concentrations of Parathyroid Hormone (PTH) are Associated with Reduced Gait Velocity in Adults: A Systematic Review.

Introduction/objectives: High serum concentrations of parathyroid hormone (PTH) have been associated with osteoporosis, sarcopenia and osteosarcopenia. Gait velocity is a predictor of adverse outcomes. This systematic review aimed to assess the observational evidence studying the association of PTH concentrations with gait velocity in adults.

Misreporting of dietary energy intake obtained by 24 h recalls in older adults: a comparison of five previous methods using doubly labeled water.

Background/objective: To test five different methods to detect misreporting in comparison to doubly labeled water in a sample of older adults.

Subjects/methods: A cross-sectional study with thirty-eight Brazilian community-dwelling older adults aged 60-84 years, who had their total energy expenditure measured by doubly labeled water (TEE). Dietary data were collected by two 24 h recalls.

Estimating total daily energy requirements in community-dwelling older adults: validity of previous predictive equations and modeling of a new approach.

Background/objectives: Accurate estimation of energy requirements is crucial for health maintenance and prevention of malnutrition in older adults. This study aimed to assess the accuracy of predictive equations for estimating energy requirements in older adults and to test the validity of new predictive equations for this age group.

Subjects/methods: This is a cross-sectional study including 38 Brazilian community-dwelling older adults aged 60-84 years, who had their total energy expenditure measured by doubly labeled water (TEE).

Correlations among vitamin K intake, body fat, lipid profile and glucose homeostasis in adults and the elderly.

Objective Recent research has investigated the possible inverse relationship between vitamin K intake and body fat. In addition, an increasing number of studies are supporting a key role for this vitamin in improving lipid profile and insulin sensitivity and reducing the risk of type 2 diabetes mellitus, but little is known about what mechanisms would be involved. Thus, the objective of this study was to investigate the relationship between vitamin K intake (in the form of phylloquinone - PK), body fat, lipid profile and markers of glucose homeostasis in adults and the elderly.

High parathyroid hormone levels are associated with poor balance in older persons: A cross-sectional study.

Objectives: A high level of parathyroid hormone (PTH) was recently identified as a risk factor for falling. As balance instability is one of the major risk factors for falls, we aimed to investigate whether high PTH concentrations are associated with poor balance in older persons.

Study Design: Cross-sectional study with 127 community-dwelling older adults (75% female), aged 65-96 years, at the Falls and Fracture Clinic, Western Health-Sunshine Hospital, Melbourne, Australia.

Antioxidant intake and bone status in a cross-sectional study of Brazilian women with osteoporosis.

This study aimed to investigate the association between antioxidant intake and bone mineral density (BMD) in postmenopausal women with osteoporosis. We conducted a cross-sectional study with 150 women, mean age 68.7 (SD 9.
