Dietary patterns and decreased muscle strength incidence: findings from the Korean Genome and Epidemiology Study
Abstract
OBJECTIVES: Muscle strength is a fundamental determinant of functional capacity across adulthood. While dietary protein has been widely studied, prospective evidence considering overall dietary patterns remains inconsistent. We examined the association between macronutrient-based dietary patterns and incident decreased muscle strength among adults aged 40 years and older. METHODS: We analyzed 31,968 adults aged ≥40 years without decreased muscle strength at baseline from the Korean Genome and Epidemiology Study. The participants were categorized into four groups according to macronutrient energy proportions: high-carbohydrate, high-fat, high-protein, and normal diets. The incidence of decreased muscle strength was defined as
