cruzi infection (n = 17).

The subjects included in the analysis were younger than those who were excluded (mean ages were 68.9 years (standard deviation (SD), 7.0) and 72.4 years (SD, 9.3), respectively; p < 0.001). The baseline prevalence of T. cruzi infection was 37.5%, comprising 524 and 874 selleck chemicals llc participants in the T. cruzi-infected and non-infected groups, respectively. Females were predominant in both groups (67.9% and 56.5%, respectively). The median BNP level was 80 pg/mL (interquartile range (IQ) 43–148), with significantly higher values in the T. cruzi-infected than in the non-infected group (median BNP 121 pg/mL (IQ, 63–204.5) versus 64 pg/mL (IQ 34–112), respectively). Regarding the anthropometric measures, BMI was significantly lower in the T. cruzi-infected than in the non-infected group (24.3 (SD 5.0) versus 25.5

(SD 4.8), respectively). Waist circumference (89.2 cm (SD 11.2) versus 92.4 cm (SD 11.0)) and triceps skin-fold thickness (14.5 mm (IQ 10.2–22.2) versus 16.0 mm (IQ 11.0–23.0)) KU-60019 chemical structure were significantly lower in infected than in non-infected individuals. Overall participant characteristics and characteristics for each group are depicted in Table 1. We found an inverse relationship between BNP levels and BMI, which was independent of age and sex (B = −0.024; 95% CI −0.034 to −0.013; p < 0.001). This association remained highly significant in the fully adjusted model (B = −0.018; enough 95% CI −0.028 to −0.008; p < 0.001). We also found an inverse association between waist circumference and BNP levels in the age–sex adjusted model (B = −0.008; 95% CI −0.013 to −0.004; p < 0.001) and in the fully adjusted model (B = −0.005; 95% CI −0.010 to −0.001; p < 0.05). Furthermore, an inverse relationship between BNP levels and triceps skin-fold thickness was also found in both univariate and adjusted models (B = −0.193; 95% CI −0.306 to −0.081; p < 0.01) Both T. cruzi-infected (B = −0.021; 95% CI −0.039 to −0.005; p = 0.013) and non-infected (B = −0.015; 95% CI −0.028 to −0.003; p = 0.017)

subjects showed a significant inverse association between BNP levels and BMI. Statistically significant associations between BNP levels and waist circumference (B = −0.009; 95% CI −0.017 to −0.002; p = 0.017) and triceps skin-fold thickness (B = −0.328; 95% CI −0.517 to −0.139; p = 0.001) were verified among T. cruzi-infected subjects; however, this association was not statistically significant in the non-infected group (B = −0.003; CI −0.008 to 0.002; p = 0.222 and B = −0.105; CI −0.246 to 0.362; p = 0.145, respectively). In addition, the differences of the regression coefficients between the infected and non-infected groups were not statistically significant for any of the anthropometric measures considered in the present analysis (p-values = 0.562, 0.178 and 0.390 for BMI, waist circumference and log triceps skin-fold, respectively).
