(P22-054-20) Association Between Type of Dietary Patterns and Handgrip Strength in Korean Children and Adolescents

Objectives: To investigate the association between dietary patterns and handgrip strength in Korean youth population.

Methods: This cross-sectional study used HGS and HGSWR data from 2,327 participants aged 10 to18 years in the Korean National Health and Nutrition Examination Survey (KNHANES) in 2014-2017. Overall food intake data was subcategorized into 25 food groups from the Korean Nutrient Database.

Results: The clusters were examined for nutritional value, and 3 clusters were generated: ‘ready to eat(white rice, eggs, fish, dairy products and processed food)’, ‘balanced(wholegrains, potatoes, beans, nuts, vegetables, mushrooms, fruits, eggs, fish, seaweed and dairy products)’ and ‘western style fast food(wheat/bread, noodles, sugars, meats, oils, sodas (sweetened and unsweetened) and seasonings)’. Compared with the balanced diet, participants with the convenient diet pattern were shown to have significantly lower HGS (β = −1.3,  p < 0.05) and HGSWR(β = −1.6,  p< 0.05). However, no significant association was found between HGS or HGSWR when the western style fast food diet pattern was compared to the balanced diet pattern.

Conclusions: Our findings suggest the possibility that reduced muscle quality can reflect by type of diet in Korean children and adolescents.

Funding Sources: There was no funding source for this study.
