Article Abstract
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. The incidence of sarcopenia was significantly greater in MetS group than normal group. We observed significantly differences in the amount of protein in the participants' diet that related to sex, income, and education level. The highest protein consumption group had significantly reduced abdominal obesity (44%; 0.293-0.652, P < .001), lower HDL-cholesterol (47%, 0.316-0.683, P < .001), elevated TG (45%, 0.298-0.679, P < .001), and MetS (42%, 0.293-0.598, P < .001) compared to the other groups, after adjustment for sex, income, education level. Total muscle mass were correlated positively with protein consumption, but there was a negative correlation between protein consumption and total fat mass. The present study suggests that at least 0.8 g/kg per day of protein may reduce MetS and help manage body composition changes to mitigate MetS in Korean elderly.
Background: Psoriatic arthritis (PSA) is an inflammatory joint disease associated with psoriasis (PSO) that can be easily missed. Existing PSA screening tools ignore objective serologic indicators. The aim of this study was to develop a disease screening model and the Psoriatic Arthritis Inflammation Index (PSAII) based on serologic data to enhance the efficiency of PSA screening.
Objective: To estimate the prevalence of anxiety and examine the association between the dietary diversity and anxiety among older Chinese adults.
Methods: The data from the 2018 Chinese Longitudinal Healthy Longevity Survey(CLHLS) was used, a nationwide survey with 10 555 adults aged ≥65 years in 23 provinces of China. Dietary diversity score(DDS) was constructed based on 11 items of a food frequency questionnaire.
Objective: To describe the mean systolic blood pressure and diastolic blood pressure among adults in China in 2015-2017.
Methods: The data was from the China Nutrition and Health Surveillance(2015-2017), and the research objects were from 31 provinces(autonomous regions and municipalities) in mainland China. In this study, 182 356 adults aged 18 years and above with complete blood pressure data were selected as subjects.
Radiation-induced angiosarcoma (RIAS) is a rare, late adverse event of radiotherapy comprising approximately half of all radiation-induced sarcomas. It has a relatively short latency period and generally unfavorable prognosis. This study presents a case of RIAS that developed 5 years and 11 months after the completion of hypofractionated radiotherapy (42.
