Dietary Patterns and Frailty in Older Korean Adults: Results from the Korean Frailty and Aging Cohort Study.

There are few studies on dietary patterns and frailty in Asians, and the results are controversial. Therefore, this study examined the association between dietary patterns and frailty in older Korean adults using the Korean Frailty and Aging Cohort Study (KFACS). The sample consisted of 511 subjects, aged 70-84 years, community-dwelling older people from the KFACS.

Association of serum vitamin D with frailty in older Korean adults.

Objectives: The association between serum levels of vitamin D and frailty in older Korean adults was examined.

Study Design: Cross-sectional study. Older people living in the community across 10 study centers throughout South Korea.

Diet quality and osteosarcopenic obesity in community-dwelling adults 50 years and older.

Objectives: To examine the association between diet quality and osteosarcopenic obesity (OSO), low bone and muscle mass with concurrent high fat mass, in middle-aged and older adults.

Study Design: Data were from a cross-sectional study of 2579 men and 3550 women aged 50 years and older who completed the Korea National Health and Nutritional Examination Survey from 2008 to 2010.

Main Outcome Measures: Data were collected using 24-h dietary recall, and diet quality was determined by the Diet Quality Index-International (DQI-I), on which higher scores denote better quality.

Association of serum vitamin D with osteosarcopenic obesity: Korea National Health and Nutrition Examination Survey 2008-2010.

Background: Serum vitamin D levels have been reported to be associated with individual components of body composition. However, the relationship between serum vitamin D and combined indices of adverse body composition is largely unknown. This cross-sectional study examined the association between serum vitamin D and osteosarcopenic obesity in a nationally representative sample of middle-aged and older adults.

Association between healthy diet and exercise and greater muscle mass in older adults.

Objectives: To examine the association between healthy diet and exercise, individually and combined, and low muscle mass in older Korean adults.

Design: Population-based cross-sectional study from the Fourth and Fifth Korea National Health and Nutrition Examination Surveys from 2008 to 2011.

Setting: Community.

Under-reporting of Energy Intake from 24-hour Dietary Recalls in the Korean National Health and Nutrition Examination Survey.

Objectives: Chronic degenerative diseases are closely related to daily eating habits, nutritional status, and, in particular, energy intake. In clarifying these relationships it is very important for dietary surveys to report accurate information about energy intake. This study attempted to identify the prevalence of the under-reporting of energy intake and its related characteristics based on the Korean National Health and Nutrition Examination Survey conducted in the years 2007-2009.

Association of vegetables and fruits consumption with sarcopenia in older adults: the Fourth Korea National Health and Nutrition Examination Survey.

Background: several studies have found nutrients, including antioxidants, to be associated with sarcopenia. However, whether specific foods, such as vegetables and fruits, are associated with sarcopenia has not been studied.

Objective: to examine the association of the frequency of vegetables and fruits consumption with sarcopenia in older people.
