Abstract Background Non-invasive anthropometric measurement methods such as those for measuring height and weight are crucial in pediatric patients. However, research focusing on the association between the type of dietary pattern and handgrip strength and handgrip-to-weight ratio in adolescents has not been carried out yet. Methods The current work aims to investigate the association between handgrip strength and dietary patterns in Korean adolescents. This cross-sectional analyses of the 2014-2017 Korean National Health and Nutrition Examination Survey assessed 2,327 adolescent (aged 10-18 years) who had measured handgrip strength and analyzed association between dietary pattern. The mean of three handgrip strength measurements, per hand, was used in the analysis. Handgrip-to-weight ratio was calculated by the following equation: Handgrip strength/body weight (kg)×100). The overall food intake data were subcategorized into 25 food groups from the Korean Nutrient Database. The clusters were examined for nutritional values, and the ready-to-eat , balanced, and western-style fast-food clusters were ultimately generated. The association between handgrip strength, handgrip-to-weight ratio, and dietary intake was analyzed. Results Overall, 85.6% of the participants were assigned to a ready-to-eat dietary pattern, 9.3% to a western-style fast-food dietary pattern, and 5.1% to a balanced dietary pattern. Compared with the participants following a balanced dietary pattern, those following a ready-to-eat dietary pattern were shown to have significantly lower handgrip strength and handgrip-to-weight ratio. However, no significant association was found between handgrip strength or handgrip-to-weight ratio when the western-style fast-food dietary pattern was compared to the balanced dietary pattern. Conclusions Decreased handgrip strength and handgrip-to-weight ratio value in participants following ready-to-eat dietary patterns indicate a diffuse problem in adolescents’ health and possibly imply an association between reduced muscle quality and dietary pattern. Moreover, the overall environmental factors potentially inducing such unhealthy dietary preferences should be investigated, and appropriate lifestyle changes in Korean adolescents should be encouraged.

Abstract Object: Measuring handgrip strength is a useful method to evaluate sarcopenia. No study has shown the trends of muscle quality among Korean adolescents by year. This study aimed to determine the trends of handgrip strength among Korean adolescents using data from the Korea National Health and Nutrition Examination Survey (KNHANES). Data of 2,304 adolescents who participated in the KNHANES between 2014 and 2017 were obtained. Muscle quality was estimated by dividing handgrip strength by body weight (handgrip-to-weight ratio). The handgrip-to-weight ratios were categorized by age, sex, and year. Results: Handgrip strength in adolescents decreased from 28.67kg in 2014 to 27kg in 2017. (P for trend<0.05) The handgrip-to-weight ratio also decreased from 51.48 in 2014 to 48.18 in 2017 (P for trend<0.05). The handgrip strength and handgrip-to-weight ratio also decreased among boys and girls over the years 2014–2017 (P for trend<0.05). The results of the present study indicate that the handgrip-to-weight ratio decreased in Korean adolescents from the years 2014 to 2017, and a declining overall ratio indicates a decrease in the quality of muscles among Korean adolescents. Hence, there is a need to review the health status of Korean adolescents.

Abstract Background: The incidence of obesity, metabolic syndrome, and nonalcoholic fatty liver disease among adolescents is increasing worldwide. Adolescents are also known to have sarcopenia along with these conditions. Measuring handgrip strength is a useful method to evaluate sarcopenia. No study has shown the trends of muscle quality (handgrip-to-weight) among Korean adolescents by year. This study aimed to determine the trends of handgrip strength among Korean adolescents using data from the Korea National Health and Nutrition Examination Survey (KNHANES).Methods: Data of 2,304 adolescents (1,227 boys; 1,077 girls; age, 10–18 years) who participated in the KNHANES between 2014 and 2017 were obtained. Muscle quality was estimated by dividing handgrip strength by body weight (handgrip-to-weight ratio). The handgrip-to-weight ratios were categorized by age, sex, and year. Results: Handgrip strength in adolescents decreased from 28.67kg in 2014 to 27kg in 2017. (P for trend<0.05) The handgrip-to-weight ratio also decreased from 51.48 in 2014 to 48.18 in 2017 (P for trend<0.05). The handgrip strength and handgrip-to-weight ratio also decreased significantly among boys and girls over the years 2014–2017 (P for trend<0.05). Conclusions: The results of the present study indicate that the handgrip-to-weight ratio decreased in Korean adolescents from the years 2014 to 2017, and a declining overall ratio indicates a decrease in the quality of muscles among Korean adolescents. Hence, there is a need to review the health status of Korean adolescents, and measures should be taken to prevent its deterioration.
