Aim It has been reported that if nutrient intake is unbalanced, muscle mass, muscle strength and physical performance declines, and therefore it is important to maintain chewing ability to keep a balanced nutrient intake. However, the relationship between chewing ability and sarcopenia has not been previously reported. Therefore, the present study investigated the relationship between chewing ability and sarcopenia in addition to known sarcopenia‐related factors. Methods We examined 761 participants (average age 73.0 ± 5.1 years), who lived in the I tabashi city of T okyo. Our research was designed to examine the relationship between chewing ability and sarcopenia. We carried out regression analysis to analyze the relationship with sarcopenia‐related factors with consideration of the age of the participants. Results The 761 participants were divided into two groups in terms of the stage of sarcopenia according to whether there was a deterioration of muscle strength or physical performance. Furthermore, we carried out logistic regression analyses on the value as a dependent variable, including known sarcopenia‐related factors. There were significant correlations of sarcopenia with age (odds ratio 2.37, 95% confidence interval 1.52–3.70), body mass index (odds ratio 0.75, 95% confidence interval 0.69–0.81) and chewing ability (odds ratio 2.18, 95% confidence interval 1.21–3.93). Conclusions The present study shows that chewing ability is related to sarcopenia, which is equal to the relationship with the known factor of age by odds ratio.
