Effects of an intervention in eating habits and physical activity in Japanese-Brazilian women with a high prevalence of metabolic syndrome in Bauru, São Paulo State, Brazil

We evaluated the impact of a lifestyle intervention on the cardiometabolic risk profile of women participating in the Study on Diabetes and Associated Diseases in the Japanese-Brazilian Population in Bauru. This was a non-controlled experimental study including clinical and laboratory values at baseline and after a 1-year intervention period. 401 Japanese-Brazilian women were examined (age 60.8±11.7 years), and 365 classified for metabolic syndrome (prevalence = 50.6%). Subjects with metabolic syndrome were older than those without (63.0±10.0 vs. 56.7±11.6 years, p < 0.01). After intervention, improvements in variables were found, except for C-reactive protein. Body mass index and waist circumference decreased, but adiposity reduction was more pronounced in the abdominal region (87.0±9.7 to 84.5±11.2cm, p < 0.001). Intervention-induced differences in total cholesterol, LDL, and post-challenge glucose were significant; women who lost more than 5% body weight showed a better profile than those who did not. The lifestyle intervention in Japanese-Brazilian women at high cardiometabolic risk improved anthropometric and laboratory parameters, but it is not known whether such benefits will persist and result in long-term reduction in cardiovascular events.

Within- and between-person variations as determinant factors to calculate the number of observations to estimate usual dietary intake of adolescents

This cross-sectional study describes the variation in the dietary intake of energy and macronutrients based on estimated coefficients of within- and between-person variation and intends to calculate the number of days required to evaluate the dietary intake of adolescents in Piracicaba, Brazil. The sample was made up by ninety-two adolescents aged between eleven and sixteen years. Interviews were performed to assess demographic, anthropometric and dietary variables, which were evaluated by the answers obtained through two 24-hour recalls. Descriptive analyses were performed and variances and Coefficients of variation within- and between-person were obtained by results of one-way ANOVA. The mean energy intake observed was 2,326.2 kilocalories; mean macronutrient intake came to 89.0 grams of fatty acids, 305.3 grams of carbohydrates and 82.2 grams of proteins. Coefficients of within-person variation ranged from 36% to 45%, while between-person coefficients varied from 26% to 31%. Variance ratios ranged from 1.35 (carbohydrate) to 2.62 (protein). The lowest number of observations required to correctly evaluate the usual diet calculated (r = 0.90) was six days, for carbohydrates while the highest was eleven, for proteins. Coefficients of variation were similar to those observed in international studies. We conclude that, in this study, two observations were sufficient to obtain reasonable correlations. However, six evaluations are necessary for these adolescents in order to obtain excellent correlations.

Associação entre prática de atividade física, escolaridade e perfil alimentar de motoristas de caminhão

A demanda da sociedade moderna intensificou o trabalho ininterrupto em diversas profissões. Além disso, o modo de organização da sociedade, com atividades predominantemente mecanizadas, tem contribuído para a prevalência de hábitos de vida não saudáveis, como a inatividade física. Este estudo objetiva verificar se fatores ocupacionais, sociodemográficos, antropométricos e alimentares estão associados à prática de atividade física insuficiente e se há diferenças nessa associação entre motoristas de caminhão que trabalham de dia ou à noite. Participaram da pesquisa 470 motoristas de caminhão, que responderam a questionários de dados sociodemográficos, atividade física e frequência alimentar. Foi realizada uma regressão logística univariada para verificar a associação entre atividade física insuficiente e as demais variáveis. Além disso, a regressão logística múltipla foi testada para obter modelos que mostrem a associação de conjuntos de variáveis relacionados à atividade física insuficiente. Os resultados indicaram que a prática de atividade física está associada ao maior nível de escolaridade (OR = 1,84; IC = 1,22-2,76) e menor consumo de bebidas alcoólicas (OR = 1,59; IC = 1,04-2,45). Maior ingestão de cereais integrais (OR = 1,63; IC = 1,08-2,46) foi associada à prática regular de atividade física. Entre os trabalhadores noturnos, foi encontrada associação entre a prática regular de atividade física, maior consumo de cereais integrais (OR = 2,02; IC =1,13-3,60) e menor consumo de carboidratos simples (OR = 1,91; IC = 1,08-3,37).

Evolução de parâmetros antropométricos em portadores do vírus da Imunodeficiência Humana ou com Síndrome da Imunodeficiência Adquirida: um estudo prospectivo

OBJETIVO: Avaliar o estado nutricional e a evolução de parâmetros antropométricos para alterações morfológicas em pacientes vivendo com o vírus da Imunodeficiência Humana ou com Síndrome da Imunodeficiência Adquirida em uso de terapia antirretroviral de alta atividade. MÉTODOS: Trata-se de estudo de coorte prospectiva com duração de 12 meses, envolvendo indivíduos adultos, de ambos os sexos, em terapia antirretroviral recém introduzida. Os indicadores antropométricos estudados foram índice de massa corporal, circunferência de cintura, dobras cutâneas subescapular, biciptal e triciptal, avaliados com intervalos de três meses, totalizando 4 medidas do tempo. Variáveis foram descritas segundo mediana e percentis 25 e 75 e analisadas por ANOVA para medidas repetidas. RESULTADOS: A população estudada foi composta por 53 indivíduos, a maioria do sexo masculino (81%), entre 30 e 39 anos. Apenas a dobra cutânea subescapular apresentou significante variação no tempo (T1=13,7 vs T4=16,0; p<0,001), apontando para lipo-hipertrofia dorso-cervical. CONCLUSÃO: Os achados deste estudo, embora limitados, direcionam para a necessidade de vigilância de parâmetros antropométricos associados a alterações morfológicas, em especial, aqueles usados no diagnóstico de acúmulo de gordura abdominal e dorso-cervical.

The burden of physical activity on type 2 diabetes public healthcare expenditures among adults: a retrospective study

Background: Determinants of public healthcare expenditures in type 2 diabetics are not well investigated in developing nations and, therefore, it is not clear if higher physical activity decreases healthcare costs. The purpose of this study was to analyze the relationship between physical activity and the expenditures in public healthcare on type 2 diabetes mellitus treatment. Methods: Cross-sectional study carried out in Brazil. A total of 121 type 2 diabetics attended to in two Basic Healthcare Units were evaluated. Public healthcare expenditures in the last year were estimated using a specific standard table. Also evaluated were: socio-demographic variables; chronological age; exogenous insulin use; smoking habits; fasting glucose test; diabetic neuropathy and anthropometric measures. Habitual physical activity was assessed by questionnaire. Results: Age (r = 0.20; p = 0.023), body mass index (r = 0.33; p = 0.001) and waist-to-hip ratio (r = 0.20; p = 0.025) were positively related to expenditures on medication for the treatment of diseases other than diabetes. Insulin use was associated with increased expenditures. Higher physical activity was associated with lower expenditure, provided medication for treatment of diseases other than diabetes (OR = 0.19; p = 0.007) and medical consultations (OR = 0.26; p = 0.029). Conclusions: Type 2 diabetics with higher enrollment in physical activity presented consistently lower healthcare expenditures for the public healthcare system.

Analysis of the effects of conical indentation variables on the indentation response of elastic-plastic materials through factorial design of experiment

In this work, the effects of conical indentation variables on the load-depth indentation curves were analyzed using finite element modeling and dimensional analysis. A factorial design 2(6) was used with the aim of quantifying the effects of the mechanical properties of the indented material and of the indenter geometry. Analysis was based on the input variables Y/E, R/h(max), n, theta, E, and h(max). The dimensional variables E and h(max) were used such that each value of dimensionless Y/E was obtained with two different values of E and each value of dimensionless R/h(max) was obtained with two different h(max) values. A set of dimensionless functions was defined to analyze the effect of the input variables: Pi(1) = P(1)/Eh(2), Pi(2) = h(c)/h, Pi(3) = H/Y, Pi(4) = S/Eh(max), Pi(6) = h(max)/h(f) and Pi(7) = W(P)/W(T). These six functions were found to depend only on the dimensionless variables studied (Y/E, R/h(max), n, theta). Another dimension less function, Pi(5) = beta, was not well defined for most of the dimensionless variables and the only variable that provided a significant effect on beta was theta. However, beta showed a strong dependence on the fraction of the data selected to fit the unloading curve, which means that beta is especially Susceptible to the error in the Calculation of the initial unloading slope.

Depressive symptoms in old age: relations among sociodemographic and self-reported health variables

Background: Depression in old age is a complex multifactorial phenomenon that is influenced by several biopsychosocial variables. Depressive symptoms are associated with the presence of chronic diseases, with being female, with low education and low income levels, and with poor perceived health assessment. In impoverished areas, older adults may have more physical disability, as they may have less access to health services. Therefore, they may be more likely to report depressive symptoms. Methods: Population-based cross-sectional research was undertaken using data from the FIBRA study conducted in Ermelino Matarazzo, a poor subdistrict of the city of Sao Paulo, Brazil. The participants comprised 303 elderly people, aged 65 years and over, who attended a single-session data collection effort carried out at community centers. The protocol comprised sociodemographic and self-reported health variables, and the Geriatric Depression Scale. Results: The majority of the subjects reported five or fewer symptoms of depression (79.21%), reported one or two self-reported chronic diseases (56.86%), declared themselves to have one or two self-reported health problems (46.15%), and had good perceived health assessment (40.27%). The presence of depressive symptoms was associated with a higher number of self-reported health problems, poor perceived health assessment, and lower schooling levels, in the total sample and in analyses including men only. For women, depressive symptoms were associated with the number of self-reported health problems and family income. Conclusion: The presence of health problems, such as falls and memory problems, lower perceived health, and low education (and low family income for women) were associated with a higher presence of depressive symptoms among elderly people in this poor area of Sao Paulo.
