Abstract
Background: Blood leptin concentration is related to fat mass, adipose cell and leptin receptor function, and
comorbidities. The aim of this study is to determine the relationships between blood leptin concentration
and nutritional status assessment among inpatients with stable cardiovascular disorders.
Materials and Methods: Blood leptin concentration and nutritional risk and status assessments using clinical,
anthropometric and biochemical parameters, as well bioelectrical impedance (BIA), were determined in
160 consecutive inpatients with mild exacerbation of cardiovascular diseases cardiovascular disorders
undergoing non-urgent hospitalization.
Results: Patients with lower values of Minimal Nutritional Assessment score had lower blood leptin concentration
and lower value of leptin to CRP ratio. Compared to patients with leptin concentration in the
upper quartiles, individuals in the lowest quartile had a lower BMI and fat mass, thinner skinfolds, greater
skeletal muscle mass and handgrip strength. In comparison with the values for leptin-to-CRP ratio, albumin,
albumin-to-CRP ratio and lymphocyte count, leptin explained a greater part of the variance in the majority
of parameters of nutritional status and body composition. Contrasting associations of leptin with ideal
(negative) and current (positive) body mass were found.
Conclusions: Leptin was associated with parameters of nutritional status assessments more strongly
than other biochemical parameters usually used. However, the use of leptin as a biomarker of nutritional
status should be approached carefully and needs further evaluation, especially in the context of its strong
association with both current and ideal body mass, the importance of receptors’ resistance to leptin, and
leptin’s negative relationships with muscle mass and strength.
