The Impact of High Carbohydrate Intake on Physical Frailty in Older Korean Adults: a Cohort-based Cross-sectional Study


 Background: The relationship between macronutrients and frailty is unclear. Previous studies have confirmed the relationships between energy and protein intake and physical frailty, while few studies have examined the role of carbohydrate or fat intake in the prevalence of frailty. The aim of this study is to investigate the relationship of energy and macronutrients with physical frailty in the Korean elderly population who had a high proportion of energy intake from carbohydrates.Methods: This study included 954 adults aged 70 to 84 years who have completed the assessment of frailty and 24-h recall upon enrolment in the Korean Frailty and Aging Cohort Study and have no extreme intake under 400 kcal (n = 2). The relationship between energy or macronutrients and frailty was evaluated using multivariate logistic regression models and multivariate nutrient density models.Results: In the subjects with low energy intake (odds ratio [OR] = 2.94, 95% confidence interval [CI] = 1.34–6.45) and total subjects (OR = 2.01, 95% CI = 1.03–3.93), consuming carbohydrates above the acceptable macronutrient distribution range (65% of energy) was related to a higher risk of frailty. Substituting the energy from fat with carbohydrates was related to a higher risk of frailty (1%, OR = 1.05, 95% CI = 1.00–1.09; 5%, OR = 1.26, 95% CI = 1.02–1.56; 10%, OR = 1.59, 95% CI = 1.03–2.43).Conclusions: This study showed that the proportion of energy intake from carbohydrates and fats may be an important nutritional intervention factor for reducing the risk of frailty.
