Rationale: The lack of a sensitive, low-cost and practical method in internal patients to assess the nutritional status makes this analyses complex. We verify the correlation between adductor pollicis muscle thickness (APMT),the mid-arm muscle circumference (MAMC) and body mass index (BMI), as well as the prognosis.
Methods: The data of patients ≥60 years old from January to December 2011 in 2 private hospitals were: height, body weight; arm circumference and MAMC; triceps skin fold and APMT; length of stay (LOS) and outcome. We used the statistical software R version 2.15. The association between variables was evaluated using the Pearson test. Test - χ2 was used to verify this correlation and statistic kappa the agreement between the 3 anthropometric parameters. Kappa levels were as follow: <0,40= poor; 0,40 to 0,75= good and >0,75= excellent agreement. Significant statistical: p≤0,05.
Results: 279 patients were select: 44% male and 56% female, median age of 81.89±8.06 years old. Media of APMT was 8,78±3,47 mm. The APMT was correlated with all anthropometric variables (p<0,05). APMT was the only tool that was significantly associated with the prognosis (p<0,001). Average of length of stay was 21 days and APMT and BMI were associated with this parameter (p<0,01). The level of agreement between the variables was poor (к<0,24).
Conclusion: Variables which reflect the lean body mass (LBM) correlate with prognosis, LOS and nutritional status. The poor agreement between the LBM indexes (MAMC and APMT) and BMI highlight the use at least 2 anthropometric tools for prognostic analysis. Our results of average APMT suggest that further research in the health elderly population are necessary.
