The Function of Body Mass Index in the Older with Osteosarcopenia: A Systematic Review and Meta-analysis.

Background: Due to the aging population worldwide, diseases that frequently attack elderly people, such as sarcopenia and osteoporosis, are major public health issues.

Methods: This study used a systematic review and meta-analysis to examine the associations among body mass index (BMI), sarcopenia, and bone mineral density (BMD) in a group of adults older than 60 years. Eight studies with a total of 18,783 subjects were examined using a random effect model.

Does vitamin D affect sarcopenia with insulin resistance in aging?

There are many studies investigating nutritional factors that affect both sarcopenia and muscle formation. According to extensive research, protein has an essential role in muscle formation. More recently, vitamin D has emerged as an important factor that regulates muscle metabolism.

Effects of Soy Foods in Postmenopausal Women: A Focus on Osteosarcopenia and Obesity.

Chronic diseases in postmenopausal women are caused by rapid changes in hormones and are accompanied by rapid changes in body composition (muscle, bone, and fat). In an aging society, the health of postmenopausal women is a social issue, and people's interest in ingesting high-quality protein is increasing in order to maintain a healthy body composition. This review aims to summarize the efficacy of soy foods and their impact on body composition.

Advantage of Dairy for Improving Aging Muscle.

The risk of sarcopenia increases with aging. Malnutrition in the elderly population is an important risk factor for sarcopenia. Calcium (Ca), phosphate (P), vitamin D and protein are key nutrients for the human body and affect muscle mass and quality.

The Quality of a Traditional Dietary Pattern in Relation to Metabolic Syndrome in Elderly South Koreans.

Background: The most beneficial dietary pattern in managing metabolic syndrome (MetS) in the elderly has not been ascertained. The aim of this study is to classify dietary patterns and to examine associations between dietary pattern, MetS and body composition in elderly Koreans.

Methods: This study was conducted among Koreans 65 years or older using data from the Korea National Health and Nutrition Examination Survey in 2009.

Associations between Sarcopenia and Metabolic Risk Factors: A Systematic Review and Meta-Analysis.

Background: Metabolic risk factors can impact sarcopenia, but the direct relationship of metabolic risk factors with sarcopenia has not been examined. Our purpose was to investigate the effects of metabolic risk factors on sarcopenia in older adults.

Methods: Sixteen studies were found through a search of electronic databases and were subjected to a meta-analysis to investigate the differences in metabolic risk factors between patients with sarcopenia and controls.

Appropriate protein intake is one strategy in the management of metabolic syndrome in Korean elderly to mitigate changes in body composition.

Higher protein intake could reduce metabolic syndrome (MetS) by managing body composition among Korean elderly although the research is scant. Herein, we examined the hypothesis that the optimal protein intake of Korean elderly is associated with both improvements in MetS risk as well as favorable changes in body composition. The present study employs a national data source, the Korea National Health and Nutrition Examination Survey (KNHANES, 2009), and a total 1,567 elderly (651 men and 916 women) were included in the final data analyses.

Does Protein Intake Affect Metabolic Risk Factors among Older Adults in Korea?

Background: Carbohydrate intake can impact metabolic risk factors, but related research on protein intake in the elderly is rare. Our purpose was to estimate protein intake and explore how different levels of protein intake influence metabolic risk factors in Korean older adults.

Methods: Data were obtained from men aged 51-70 years (n=1,735), men aged ≥71 years (n=700), women aged 51-70 years (n=2,305), and women aged ≥71 years (n=957).

The most effective factors to offset sarcopenia and obesity in the older Korean: Physical activity, vitamin D, and protein intake.

Objective: The aim of this study was to evaluate the effects of the types and levels of physical activity in conjunction with protein intake and vitamin D on sarcopenia and obesity status in an elderly population.

Methods: Study participants (N = 4452) were ages ≥60 y and included 1929 men and 2523 women who completed a body composition analysis with a dual energy x-ray absorptiometry and provided health and dietary data.

Results: Higher appendicular skeletal muscle mass/weight was observed in the non-obese group, although obese participants had greater weights.

Can nutrition label recognition or usage affect nutrition intake according to age?

Objectives: The aim of this study was to investigate the effect of the use of nutrition labeling on nutritional intake according to age groups, focusing on Korean elderly.

Methods: Study participants (N = 5223) were adults at least 20 y of age and had participated in the Korean National Health Examination and Nutrition Survey in 2012. Data for recognition/use of nutrition labels were obtained by self-report.

Impact of dining out on nutritional intake and metabolic syndrome risk factors: data from the 2011 Korean National Health and Nutrition Examination Survey.

The frequency of dining out has rapidly increased; however, the independent associations between dining out, metabolic syndrome risk factors and nutritional status have not been well characterised. The aim of the present study was to investigate the associations between dining out, nutritional intakes and metabolic syndrome risk factors among Korean adults, using data from the 2011 Korean National Health and Nutrition Examination Survey. Frequency of dining out was significantly associated with intake of nutrients such as energy, water, protein, fat, carbohydrate, Ca, Na, vitamin A and carotene.

Body composition changes were related to nutrient intakes in elderly men but elderly women had a higher prevalence of sarcopenic obesity in a population of Korean adults.

In this study, we examined the relationship between sarcopenic obesity (SO) and nutrition status, according to sex in Korean adults who were 60 years or older. Body composition was categorized as SO, sarcopenic nonobesity, nonsarcopenic obesity, and nonsarcopenic nonobesity. Obesity was defined by body mass index.

Dietary pattern classifications with nutrient intake and body composition changes in Korean elderly.

Background/objectives: The body composition changes in aging increased the risk of metabolic disorder. Recent dietary studies have increasingly focused on the correlations between dietary patterns and chronic diseases to overcome the limitations of traditional single-nutrient studies because nutrients in food have complex relations that interact.

Subjects/methods: This study was conducted to classify a dietary pattern among Korean elderly using cluster analysis and to explore the relationships between dietary patterns and body composition changes in Korean elderly aged 65 years or older.

Applying the Health Belief Model to college students' health behavior.

The purpose of this research was to investigate how university students' nutrition beliefs influence their health behavioral intention. This study used an online survey engine (Qulatrics.com) to collect data from college students.

5-Hydroxytrytophan inhibits tert-butylhydroperoxide (t-BHP)-induced oxidative damage via the suppression of reactive species (RS) and nuclear factor-kappaB (NF-kappaB) activation on human fibroblast.

5-Hydroxytryptophan (5HTP), an analogue of tryptophan, is a precursor of serotonin that also has effective antioxidative and anti-apoptotic properties (1) . However, the cellular mechanisms underlying these properties of 5HTP have not been explored. In this study, we tested the hypothesis that 5HTP exerts its antioxidative action against oxidative stress and inflammation by suppressing the activation of the key pro-inflammatory transcriptional pathways, p38 mitogen-activated protein kinase (p38MAPK) and nuclear factor-kappaB (NF-kappaB).

Modulation of age-related NF-kappaB activation by dietary zingerone via MAPK pathway.

Zingerone, a major component found in ginger root, has been known as anti-mutagenic and anti-carcinogenic activities that are often associated with its anti-oxidative and anti-inflammatory activities. In recent studies, we examined molecular mechanism of zingerone treatment on pro-inflammatory NF-kappaB activation via the redox-related NIK/IKK and MAPK pathways. Action mechanism of zingerone on NF-kappaB signaling was investigated in aged rat kidney and endothelial cells.
