背景：与肥胖相关的肌肉力量下降是老年人的一个重要公共卫生问题。膳食蛋白质与肌肉质量的维持有关，但其与肌肉力量的关系尚不清楚。（总的，动物的，和植物的）摄入量，通过食物频率调查问卷测量，在6年中握力的变化在1，746名男性和女性从Frachial Offspring队列。（范围：29-85），平均总，动物和植物蛋白摄入量分别为79，57和22克/天。调整后的基线平均握力在能量调整后的总摄入量、动物摄入量或蛋白质摄入量的四分位数之间没有差异。无论蛋白质来源如何，蛋白质摄入量越大，握力下降越少（趋势均为p
Background: Age-related decline in muscle strength is an important public health issue for older adults. Dietary protein has been associated with maintenance of muscle mass, yet its relation to muscle strength remains unclear.Methods: We determined the association of dietary protein (total, animal, and plant) intake, measured by food frequency questionnaire, with change in grip strength over 6 years in 1,746 men and women from the Framingham Offspring cohort.Results: Mean age at baseline was 58.7 years (range: 29-85), and mean total, animal, and plant protein intakes were 79, 57, and 22 g/d, respectively. Adjusted baseline mean grip strength did not differ across quartiles of energy-adjusted total, animal or protein intake. Greater protein intake, regardless of source, was associated with less decrease in grip strength (all p for trend
