Background Energy intake is important for the maintenance of muscle mass. The relationship between energy intake and sarcopenia in elderly patients with type 2 diabetes (T2D) has been unclear. Methods Using a brief‐type self‐administered diet history questionnaire we assessed habitual food and nutrient intake of patients with T2D aged ≥65 years, all of whom were Japanese and physically active, taking part in the KAMOGAWA‐DM cohort study. Patients' body composition was evaluated by bioimpedance analysis. Sarcopenia was defined as having both a grip strength of &lt;26 kg for men and &lt;18 kg for women and a skeletal muscle mass index of &lt;7.0 kg/m 2 for men and &lt;5.7 kg/m 2 for women. Logistic regression analyses were used to investigate the effect of energy intake on the presence of sarcopenia in this cross‐sectional study of 391 patients (205 men, 186 women). Results Fifty‐five patients (14.1%) were diagnosed as having sarcopenia. Energy intake was significantly lower in patients with sarcopenia than without sarcopenia (mean ± SD [n = 366] 1498.8 ± 389.4 vs 1786.2 ± 706.7 kcal/d, respectively; P = 0.016). After adjusting for age, sex, exercise, smoking status, HbA1c, and body mass index, patients' energy intake (per 100 kcal) was negatively associated with the presence of sarcopenia (odds ratio 0.86; 95% confidence interval 0.78‐0.95; P = 0.001). Conclusion Energy intake was negatively associated with the presence of sarcopenia in elderly patients with T2D.
