ABSTRACT=<sec><title>Objectives</title><p>To investigate the relationship between dietary fiber intake and skeletal muscle mass, body fat mass, and muscle-to-fat ratio (MFR) among men and women with type 2 diabetes (T2D).</p></sec><sec><title>Methods</title><p>This cross-sectional study involved 260 men and 200 women with T2D. Percent skeletal muscle mass (%) or percent body fat mass (%) was calculated as (appendicular muscle mass [kg] or body fat mass [kg]/body weight [kg]) × 100. MFR was calculated as appendicular muscle mass divided by body fat mass. Information about dietary fiber intake (g/day) was obtained from a brief-type self-administered diet history questionnaire.</p></sec><sec><title>Results</title><p>Dietary fiber intake was correlated with percent body fat mass (<italic>r</italic> = –0.163, <italic>p</italic> = 0.021), percent skeletal muscle mass (<italic>r</italic> = 0.176, <italic>p</italic> = 0.013), and MFR (<italic>r</italic> = 0.157, <italic>p</italic> = 0.026) in women. However, dietary fiber intake was not correlated with percent body fat mass (<italic>r</italic> = –0.100, <italic>p</italic> = 0.108), percent skeletal muscle mass (<italic>r</italic> = 0.055, <italic>p</italic> = 0.376), and MFR (<italic>r</italic> = 0.065, <italic>p</italic> = 0.295) in men. After adjusting for covariates, dietary fiber intake was correlated with percent body fat mass (β = 0.229, <italic>p</italic> = 0.009), percent skeletal muscle mass (β = 0.364, <italic>p</italic> &lt; 0.001), and MFR (β = 0.245, <italic>p</italic> = 0.006) in women. Further, dietary fiber intake was related to percent skeletal muscle mass (β = 0.221, <italic>p</italic> = 0.008) and tended to be correlated with percent body fat mass (β = 0.148, <italic>p</italic> = 0.071) in men.</p></sec><sec><title>Conclusion</title><p>Dietary fiber intake was correlated with skeletal muscle mass, body fat mass, and MFR among women with T2D.</p></sec>
