Abstract Introduction The global obesity epidemic has mobilized health services to offer care at all levels, with reference outpatient clinics playing a prominent role in cases of greater complexity. Objectives The present study aimed to identify soft drinks consumption and physical activity habits among children and adolescents diagnosed with overweight and obesity during the first visit at a secondary level nutrology outpatient clinic, and to verify attendance at follow-up visits in a 2-year period from the first visit. Materials and Methods This is a retrospective, descriptive study based on data collection from medical records of overweighted or obese patients receiving first care at the Nutrology Clinic of the Municipal Health Secretariat from Ribeirão Preto, São Paulo, Brazil. The study population included children and adolescents aged between 2 and 18 years old cared for from January 2, 2013 to December 30, 2017. Age, weight, height, soft drinks consumption, physical activity, and attendance in scheduled follow-up visits during a 2-year period were analyzed. Results During the study period, 316 patients were registered, including 302 (95.5%) diagnosed with obesity. Of these, 112 (35.4%) were children and 204 (64.6%) were adolescents. Only 2.0% of the children and adolescents did not consume soft drinks, while 23.5 and 26.2% of the children and adolescents, respectively, consumed them daily. Physical inactivity was reported by 31.8% of the children and by 35.8% of the adolescents. Among those who practiced some type of physical activity, 81.3% of the children and 78.2% of the adolescents did not meet the recommendation of moderate to vigorous activity for 60 minutes per day. Dropout rates within the 1st year were of 41.9% for children and of 34.3% for adolescents, increasing to 76.9% and 73.8%, respectively, within the 2nd year. Conclusion There was a high consumption of soft drinks and low adherence to physical activity among patients who started outpatient follow-up. A small adherence to the follow-up program was also identified, with high dropout rates within the 2-year period following the first visit.

ABSTRACT Objective: to verify persistence of metabolic syndrome (MetS) and components in overweight children and adolescents, as well as its relation to socioeconomic and demographic characteristics and to the Pathobiological Determinants of Atherosclerosis in Youth (PDAY) score. Method: a two-point longitudinal study: at enrollment and after a 24-month interval, with 133 individuals ages from two to 18 years. The demographic anthropomorphic and blood variables were evaluated. Analysis was carried out by simple and paired association tests, as well as multiple logistic regression. Results: persistent MetS was observed in 38.3% of the sample, associated cardiovascular risk (ACR) in 79.7%, reduction in arterial pressure and do HDL-c. After adjusting for age and sex, excess weight (ExpB: 0.182; CI: 0.059-0.561), low HDL-c (ExpB: 9.247; CI: 1.157-73.930) and high LDL-c (ExpB:1.915; CI: 0.921-3.979) were associated with persistent MetS. Conclusion: persistent MetS was associated with obesity, HDL-c and LDL-c, but not with the PDAY score.

ABSTRACT Objective: To assess and compare the impact of the Bolsa Família Program (Family Allowance) on the nutritional status of children and adolescents from the Brazilian Northeastern and Southeastern regions. Methods: The study used data from a database derived from a subsample of the Family Budget Survey conducted from 2008 to 2009. The ratios of underweight, stunted, and overweight children were calculated. Impact measurement analysis was preceded by propensity score matching, which matches beneficiary and non-beneficiary families in relation to a set of socioeconomic features. The nearest-neighbor matching algorithm estimated the program impact. Results: The ratio of underweight children and adolescents was, on average, 1.1% smaller in the beneficiary families than in the non-beneficiary families in the Northeastern region. As for the Southeastern region, the ratio of overweight children and adolescents was, on average, 4.2% smaller in the beneficiary families. The program did not affect stunting in either region. Conclusion: The results showed the positive impact and good focus of the program. Thus, once linked to structural actions, the program may help to improve the nutritional status and quality of life of its beneficiaries.

Femur bone is the longest and largest bone in the human skeleton. This bone connects the pelvic bone to the knee and carries most of the body weight. The static behavior of femur bone has been a center of investigation for many years while little attention has been given to its dynamic and vibrational behavior, which is of great importance in sports activities, car crashes and elderly falls. Investigation of natural frequencies and mode shapes of bone structures are important to understand the dynamic and vibrating behaviors. Vibrational analysis of femoral bones is presented using finite element method. In the analysis, the bone was modeled with isotropic and orthotropic mechanical properties. The effect of surrounding bone muscles has also been accounted for as a viscoelastic medium embedding the femur bone. Natural frequencies extracted considering the effects of age aggravated by weakening the elastic modulus and density loss. The effects of real complex bone geometry on natural frequencies are studied and are compared with a simple circular cross-sectional model.
