In a recent study published in the journal Clinical Nutrition ESPEN, a compelling connection between anorexia, assessed through a simplified nutritional appetite questionnaire (SNAQ), and sarcopenia among community-dwelling older adults attending outpatient rehabilitation sessions has been studied. The implications of this relationship may prove crucial for the better health and recovery of older individuals suffering from sarcopenia.

The look into the Cross-Sectional Study

The research conducted by Ishimoto Taisei and colleagues from the Department of Rehabilitation, Akahige Clinic, Kinokawa, Wakayama, Japan, aimed to elucidate the potential link between the loss of appetite and the prevalence of sarcopenia, a muscle-wasting condition common in older adults. This association had been previously reported but remained unclear within the subset of older adults engaged in outpatient rehabilitation.

Methodology and Participant Details

The study took a cross-sectional approach, investigating 120 older adults, with a marked female majority of 72.5%. These participants were involved in outpatient rehabilitation, ranging from once to thrice weekly. The main variable under investigation was sarcopenia, defined according to the criteria set out by the Asian Working Group for Sarcopenia 2019.

Measurement Tools

To measure anorexia, the study employed the SNAQ, which provides a scoring range from 4 to 20, with a score of 13 or lower indicating anorexia. Body Mass Index (BMI), food intake levels, anorexia, and a propensity score – inclusive of age, sex, number of medications, and the updated Charlson comorbidity index – served as independent variables in the forced-entry logistic regression analysis.

Key Findings:
The study revealed a sarcopenia prevalence of 65.8% (79 out of 120 subjects), with 23.3% (28 subjects) presenting with anorexia. Upon analysis, BMI (odds ratio: 0.71 [95% CI: 0.61-0.84]) and anorexia (odds ratio: 5.35 [95% CI: 1.24-23.2]) emerged as significant variables.

Significance and Conclusion

The findings point to a significant association between anorexia, as determined by the SNAQ, and sarcopenia in community-dwelling older adults undergoing outpatient rehabilitation. This highlights the importance of recognizing and assessing anorexia when examining sarcopenia in this demographic, guiding healthcare professionals towards more comprehensive assessments and potentially more effective interventions.

The study, “Association between anorexia as assessed by simplified nutritional appetite questionnaire and sarcopenia in community-dwelling older adults using outpatient rehabilitation: A cross-sectional study,” has been an essential step in understanding the interplay between two conditions that significantly affect the aging population. The use of the SNAQ as a tool in outpatient settings offers a practical and easily implemented method to identify individuals at risk and guide interventions accordingly.
