"O peso da obesidade abdominal e inatividade física em despesas de saúde no Brasil." O objetivo deste estudo foi analisar a associação entre a agregação de inatividade física com a obesidade abdominal e despesas de saúde pública em adultos brasileiros. A amostra foi composta de 963 pacientes de ambos os sexos, selecionados aleatoriamente no Sistema Único de Saúde em 2010. Gastos com saúde durante o último ano foram computados e estratificados em: consultas médicas, distribuição de medicamentos, exames laboratoriais e gasto total. A circunferência da cintura foi usada para diagnosticar a obesidade abdominal e atividade física foi avaliada através de um questionário previamente validado. Pacientes sedentários e com obesidade abdominal (OR = 3.01 [IC95% = 1.81-4.99]) apresentaram maior probabilidade de ser inserido no grupo de despesas mais elevadas do que apenas os pacientes com obesidade abdominal (OR= 1.66 [IC95%= 1.07-2.59]). Existe um efeito sinérgico entre a obesidade abdominal e sedentarismo em despesas totais de saúde.

The purpose of this study was to analyze the association between the clustering of physical inactivity with abdominal obesity and public health care expenditure in Brazilian adults. The sample was composed of 963 patients of both genders, randomly selected in the Brazilian Public Health care System during 2010. Entire health care expenditures during the last year were computed and stratified into: medical consultations, medication dispensing, laboratory tests and overall expenditure. Waist circumference was used to diagnose abdominal obesity and physical activity was assessed by previously validated questionnaire. Sedentary and abdominally obese patients (OR= 3.01 [OR95%CI= 1.81-4.99]) had higher likelihood be inserted in the group of higher expenditures than only abdominally obese patients (OR= 1.66 [OR95%CI= 1.07-2.59]). There is a synergic effect between abdominal obesity and physical inactivity on overall health care expenditures.

"El peso de la obesidad abdominal y la inactividad física en el gasto en salud en Brasil." El objetivo de este estudio fue analizar la asociación entre la agregación de la inactividad física con la obesidad abdominal y el gasto público en salud en adultos brasileños. La muestra consistió en 963 pacientes de ambos sexos, seleccionados al azar en el Sistema de la Salud en 2010. El gasto en salud en el último año se calcula y se estratificó en: consultas médicas, medicamentos, exámenes de laboratorio y el gasto total. Circunferencia de la cintura se utiliza para diagnosticar la obesidad abdominal y la actividad física se evaluó mediante un cuestionario previamente validado. Pacientes sedentarios y con obesidad abdominal (OR= 3,01 [IC95%= 1,81-4,99]) tenían más probabilidades de ser incluido en el grupo de los mayores gastos que sólo los pacientes con obesidad abdominal (OR= 1,66 [IC95%= 1,07-2,59]). Existe un efecto sinérgico entre la obesidad abdominal y la inactividad física en el gasto total en salud.

Background: It is unclear whether early physical activity has a greater influence on intima-media thickness and metabolic variables than current physical activity. Objective: To analyze the relationship between current and early physical activity, metabolic variables, and intima-media thickness measures in adults. Method: The sample was composed of 55 healthy subjects of both sexes (33 men and 22 women). Total body fat and trunk fat were estimated by dual-energy X-ray absorptiometry. Carotid and femoral intima-media thickness were measured using a Doppler ultrasound device. A 12-hour fasting blood sample collection was taken (fasting glucose and lipid profile). Early physical activity was assessed through face-to-face interview, and the current physical activity was assessed by pedometer (Digi-Walker Yamax, SW200), which was used for a period of seven days. Results: Current physical activity was negatively related to total cholesterol (rho=-0.31), while early physical activity was negatively related to triglycerides (rho=-0.42), total cholesterol (rho=-0.28), very low density lipoprotein (rho=-0.44), and carotid intima-media thickness (rho=-0.50). In the multivariate model, subjects engaged in sports activities during early life had lower values of very low density lipoprotein (b=-8.74 [b=-16.1; -1.47]) and carotid intima-media thickness (b=-0.17 [95%CI: -0.28; -0.05]). Conclusion: Early 95%CI physical activity has a significant influence on carotid intima-media thickness, regardless of the current physical activity.

OBJETIVO: analisar associações entre excesso de peso e fatores de risco familiares em diferentes âmbitos escolares. MÉTODOS: estudo descritivo/analítico de delineamento transversal com 1779 adolescentes (11 a 17 anos) de ambos os sexos, da rede pública (n=1309) e privada de ensino (n=470). Foram avaliados os fatores familiares: sexo, condição econômica, número de irmãos/televisores e escolaridade dos pais. A razão de prevalência (RP) em modelo univariado e multivariado indicou a magnitude das associações analisadas. RESULTADOS: nas escolas particulares, o excesso de peso associou-se com a escolaridade paterna (RP= 0,68 [0,5-0,9]) e sexo masculino (RP= 1,38 [1,0-1,8]). Nas escolas públicas, com a escolaridade materna (RP= 1,42 [1,1-1,8]), menor número de irmãos (RP= 1,23 [0,9-1,5]) e sexo masculino (RP= 1,32 [1,6-1,6]). CONCLUSÕES: o excesso de peso associou-se com diferentes fatores familiares, dependendo da rede de ensino em que foi analisado.

OBJECTIVE: to analyze associations between overweight and family risk factors in different school environments. METHODS: a descriptive/analytical cross-sectional study of 1779 adolescents (aged between 11 and 17 years) of both sexes in the public (n=1309) and private (n=470) education systems. Family factors evaluated included: sex, economic circumstances, number of siblings, number of televisions and level of schooling of parents. The prevalence ratio (PR) in a univariate and multivariate model suggested the scale of the associations under study. RESULTS: in private schools, overweight was associated with the level of schooling of the father (RP= 0.68 [0.5-0.9]) and with boys (RP= 1.38 [1.0-1.8]). In public schools it was associated with the level of schooling of the mother (RP= 1.42 [1.1-1.8]), having fewer siblings (RP= 1.23 [0.9-1.5]) and with boys (RP= 1.32 [1.6-1.6]). CONCLUSIONS: overweight is associated with different family factors depending on the kind of school.
