ABSTRACT:Objective: To analyze the occurrence of sleep-related disorders among adults from Presidente Prudente, Brazil, as well as to identify associations with behavioral, socio-demographic and nutritional status variables. Methods: After random selection of the sample, interviews were performed with 743 adults of both genders, living in Presidente Prudente, Brazil. Sleep-related disorders, demographic variables (sex, age, ethnicity and schooling), behavioral variables (leisure physical activity, alcohol consumption, and smoking) and nutritional status were analyzed by questionnaires. Results: The prevalence of sleep-related disorders was 46.7%, with 95% confidence interval (95%CI) 43.1 -50.2. In the multivariate analysis, female sex, with odds ratio (OR) 1.74 (95%CI 1.26 -2.40), schooling (OR = 0.49; 95%CI 0.28 -0.82), overweight (OR = 1.99; 95%CI 1.39 -2.85) and obesity (OR = 2.90; 95%CI 1.94 -4.35) were associated with sleep-related disorders. Conclusion: There is high occurrence of sleep-related disorders in this sample, which was associated with female sex, lower schooling, overweight and obesity.

Effects of HMB supplementation on body composition of rats. Int. J. Morphol., 35(2):705-710, 2017. SUMMARY:The aim was to investigate the effects of HMB supplementation on the physical performance and anthropometric parameters of Wistar rats that underwent eight weeks of concurrent training. We used 22 male Wistar rats of approximately 60 days of age, And were divided into four groups: control (C), supplemented control (SC), exercise (E) and supplemented exercise (SE). The training consisted of 30 minutes of swimming with an overload corresponding to 70 % of the anaerobic threshold, a one-minute interval, and four sets of ten jumps in water with a one minute interval between sets and a load of 50 % of body weight. After the tests, the tLIM and tTESTE were obtained and used to evaluate the performance of the animals, and anthropometric indices evaluated. The weight increases during the treatment in the SC animals was significantly higher than the animals in groups C and E. The absolute weight of the muscles, kidney and epididymal fat showed higher values for the SC and SE groups in relation to the others. ARAUJO, R. G.; CASTOLDI, R. C.; DOS SANTOS, C. C.; MACHADO, J.

The aim of the present study was to investigate the effects of β-hydroxy-β-methylbutyrate (HMB) supplementation in association with concurrent training on morphological soleus muscle of rats. Wistar male rats were divided randomly into four groups: Control (C), Supplemented (S), Training (T) and Training + Supplemented (TS). Groups S and TS received 76mg/kg/day of HMB and the training groups (T and TS) were inserted into concurrent training program 3 times/week for 8 weeks. HMB had positive effects either on body composition of the animals or in type II muscle fibers. The concurrent exercise training was able in reducing the total fat mass as well as in increasing the diameter of muscle fibers. Our findings shows that HMB had an anti-catabolic effect with reference to the parameters of volume, weight and morphology of the soleus muscle, and there was a positive interaction between HMB supplementation and concurrent exercise training.
