Relationship between Health Costs and Inflammatory Profile in Public Health.

INTRODUCTION: The association between obesity and physical activity level is well established in the literature, as well as its consequences that lead to chronic noncommunicable diseases. In addition, it is also possible to obtain the immunometabolic mechanism that explains the pathway of associations between obesity, chronic noncommunicable diseases and the level of physical activity. It also seems clear that treating illnesses has a financial impact on healthcare systems around the world, so it seems important to assess the financial impact on the healthcare system of individuals with immunometabolic dysfunction. AIM: This study aimed to assess whether there is a correlation between metabolic and inflammatory markers and healthcare costs according to body adiposity and habitual physical activity (HPA). METHODS: This is a cross-sectional study, where the sample includes men and women aged over 50. Participants underwent evaluations that included the following variables: i) immunometabolic markers, ii) healthcare costs, iii) obesity, iv) habitual physical activity, and v) history of personal illness. Statistical significance was set at values lower than 5% and the software used was BioEstat. RESULTS: The correlation between metabolic and inflammatory markers and healthcare costs demonstrated a positive and significant relationship, adjusted for obesity and HPA, between glucose concentrations and exam costs (r = 0.343, p-value = 0.007) and total cost (r = 261; p-value = 0.043); HOMA index and cost of exams (r = 0.267; pvalue = 0.038); and IL-10 and cost of medical consultation (r = 0.297; p-value = 0.020). CONCLUSION: Metabolic and inflammatory markers may be related to the costs of consultations and examinations, independent of obesity and HPA.

Cardiovascular risk factors and body fat distribution in brazilians aged 80 years or over / Fatores de risco cardiovascular e distribuição de gordura corporal em brasileiros com 80 anos ou mais

Study design: Cross-sectional study. Objective: To analyze the presence of cardiovascular risk factors (CRFs) according to the pattern of body fat distribution, in Brazilians aged 80 years or over. Methods: The sample consisted of 113 subjects, of 83.4 years, of both sexes. The percentages of total and abdominal body fat, hypertension and lipid profile were used for characterization of CRFs. The chisquare test was used to assess proportions of CRFs and the Mann-Whitney test was used to compare the results of adiposity. Results: Eutrophic subjects presented lower triglycerides (p=0.017), total cholesterol (p=0.001) and prevalence of both hypertension (p=0.003) and hypertriglyceridemia (p=0.007). Subjects with higher abdominal adiposity presented higher total cholesterol (p=0.026) and prevalence of hypertriglyceridemia (p=0.011) and hypercholesterolemia (p=0.026) than those with no excess abdominal adiposity. Those with excess fat (total, abdominal or both), with the exception of glucose(p=0.877), presented a high prevalence of CRFs. Those with both types of excess fat presented differences, with a higher prevalence level when compared to those with only one or neither of the excesses. Conclusion: Obesity, whether abdominal or total, is similarly associated with CRFs in subjects aged 80 years and over.

Modelo do estudo: Estudo transversal. Objetivo: Analisar a presença de fatores de risco cardiovascular (FRC) de acordo com o padrão de distribuição de gordura corporal em brasileiros com 80 anos ou mais. Materiais e Método: A amostra foi composta de 113 idosos, com média de idade de 83,4 anos, de ambos os sexos. O percentual de gordura corporal total e abdominal, hipertensão e perfil lipídico foram usados para caracterização dos FRC. O teste qui-quadrado foi utilizado para avaliação das proporções de FRC e o teste Mann-Whitney foi utilizado para comparar os resultados de adiposidade. Resultados: Idosos eutróficos apresentaram baixo triglicerídeos (p=0,017) e colesterol total (p=0,001) além de menores prevalências de hipertensão (p=0,003) e hipertrigliceridemia (p=0,007). Idosos com maior adiposidade abdominal apresentaram maior colesterol total (p=0,026) e prevalência de hipertrigliceridemia(p=0,011) e hipercolesterolemia (p=0,026) quando comparados com os de menor adiposidade abdominal. Aqueles com excesso de gordura (total, ou abdominal ou ambos), com exceção da glicemia (p=0,877), apresentaram alta prevalência de FRC. Aqueles com ambos os excessos de gordura apresentam diferenças, com maior nível de prevalência quando comparados aqueles com apenas um ou nenhum dos excessos. Conclusão: A obesidade, sendo abdominal ou total, é associada, da mesma maneira, com FRC em sujeitos com 80 anos ou mais.

Factors associated with leisure-time physical activity among patients undergoing hemodialysis.

BACKGROUND: End-stage renal disease patients are characterized by low levels of physical activity, especially during leisure time. However, the recognition of variables associated with patterns of physical activity in this population has been little explored. Thus, the objective was to assess factors associated with levels of physical activity during leisure time among patients on haemodialysis. METHODS: Ninety-eight patients (51.6 ± 15.7 years, 57 M/41 F) from two dialysis centres in São Paulo, Brazil participated in this cross-sectional study. Participants were divided into those who never exercised during leisure-time (inactive) and those who exercised at least once a week (active). The independent factors assessed were: socio-demographic data, comorbidities, personal barriers to exercise and physical activity records from childhood to adulthood (tracking of physical activity). RESULTS: Only 27 % of patients were engaged in PA during their leisure time at least once a week. Patients who engaged in regular physical activity during adulthood before the initiation of the hemodialysis treatment (adjusted OR: 7.24 95 % IC: 1.99; 26.50), those who developed the renal disease through diseases other than diabetes or hypertension (adjusted OR: 4.82; 95 % IC: 1.48; 15.68), and those who had no cardiovascular diseases (adjusted OR: 11.33; 95 % IC: 1.23; 103.8) where more likely to be active during their leisure-time. CONCLUSION: Comorbidities such as cardiovascular disease, hypertension and diabetes mellitus as well as the level of physical activity prior to end-stage renal disease could predict leisure-time physical activity among patients receiving hemodialysis therapy.
