SUMMARY:

Dinapenia is characterized by the loss or reduction of muscle strength and an increase in age, its development is multifactorial, being more prevalent in elderly individuals and is associated with negative short and long-term health outcomes. One of the factors that needs better understanding is the relationship with low serum levels of vitamin D (Vit. D). Vitamin D, or colecalciferol, is a steroid hormone whose main function is to regulate calcium homeostasis, bone formation, and resorption. Low serum levels of vitamin D are prevalent in elderly community-dwelling individuals, but when adequate, it seems to play an important role in maintaining muscle strength. This study aims to assess whether there is an association between dinapenia and vitamin D in community-dwelling elderly women. Method: Used was a cross-sectional study with elderly women enrolled in the Open University for the Third Age (UATI) in the city of Salvador, Bahia. Groups with and without dinapenia were divided based on the mean handgrip strength (<23 kgf) measured by a portable dynamometer. Serum vitamin D was analyzed in the form of 25-hydroxyvitamin D in ng/dl and subsequently classified as adequate or low. Other factors were evaluated to determine the association with dinapenia. The Mann-Whitney U test, Student's t-test, and chi-square test were used for association analysis. Pearson and Spearman correlation coefficients were also used. Results: Showed that out of the 147 elderly women evaluated, with an average age of 69.4 years (SD = 6.1), the prevalences of dinapenia and low serum vitamin D levels were 49.7% and 61.6%, respectively. Dinapenia was associated with low serum vitamin D levels, age, dyslipidemia, gait speed, skeletal muscle mass (SMM), and skeletal muscle mass index (SMI). Additionally, a positive correlation was found between handgrip strength and vitamin D levels, gait speed, and SMM; and a negative correlation was found between handgrip strength and age (p-value <0.05). Conclusion: The association was found between dinapenia, vitamin D, age, dyslipidemia, gait speed, low skeletal muscle mass, and low skeletal muscle mass index. Early assessment of these parameters in the healthcare of elderly women allows for appropriate interventions, avoiding associated negative outcomes.
