RESUMO
O parto cesáreo é apontado como fator de risco para diversas doenças crônicas. Neste estudo, objetivou-se averiguar a associação entre parto cesáreo e pressão arterial (PA) de crianças de 6 anos. Trata-se de estudo transversal conduzido em Feira de Santana (BA), com 635 pares de mãe e filho. O tipo de parto foi categorizado em cesárea e vaginal. A PA foi aferida por meio de esfigmomanometria e considerada elevada quando atingiu níveis iguais ou maiores ao percentil 90 para idade, sexo e altura. Razões de prevalência brutas (RPbruta) e ajustadas (RPajustada) e respectivos intervalos de confiança de 95% (IC95%) foram estimados via regressão logística múltipla. A cesariana ocorreu em 46,5% dos casos, as prevalências de pressão arterial sistólica (PAS) e diastólica (PAD) elevadas foram de 17,2% e 5,6%, respectivamente. O excesso de peso foi verificado em 28,6% das crianças. A maior prevalência de PAS elevada foi observada entre as crianças que nasceram por cesariana (61%) em relação às que nasceram por parto vaginal (RPbruta: 1,51; IC95%: 1,07-2,14; RPajustada: 1,61; IC95%: 1,05-2,46). A idade materna ao nascimento da criança foi fator de interação na associação principal, assim, as crianças nascidas via parto vaginal exibiram maior prevalência de PAS elevada, comparadas às nascidas via cesárea. O parto cesáreo se associou à PAS elevada aos 6 anos de idade.
Cesarean delivery is considered a risk factor for several chronic diseases. This study aimed to investigate the association between cesarean section and blood pressure (BP) in 6-year-old children. This is a cross-sectional study carried out in Feira de Santana, (BA) with 635 mother-child pairs. The type of birth was categorized into cesarean and vaginal. The BP was measured by using sphygmomanometry and considered high when it reached levels equal or higher than the 90th percentile for age, gender, and height. Crude (PRcrude) and adjusted (PRadjusted) prevalence rate and respective 95% confidence intervals (95%CI) were estimated by multiple logistic regression. Cesarean section occurred in 46.5% of the cases, the prevalence of high systolic (SBP) and diastolic (DBP) blood pressure were 17.2% and 5.6%, respectively. Excess weight was verified in 28.6% of the children. The highest prevalence of high SBP was among children who were born by cesarean section (61%) compared with those who were born vaginally (PRcrude: 1.51; 95%CI: 1.07-2.14; PRadjusted: 1.61; 95%CI %: 1.05-2.46). Maternal age at the birth of the child was an interaction factor in the main association, thus, children born vaginally had a higher prevalence of elevated SBP, compared with those born via cesarean section. Cesarean section was associated with increased SBP at six years of age.
El parto por cesárea presenta un factor de riesgo para varias enfermedades crónicas. El objetivo de este estudio fue investigar la asociación entre el parto por cesárea y la presión arterial (PA) en niños de 6 años de edad. Se trata de un estudio transversal, realizado en Feira de Santana, en Bahía (Brasil), con 635 pares de madre e hijo. El tipo de parto se clasificó en cesárea y vaginal. La PA se midió mediante esfigmomanometría y se consideró alta cuando alcanzó niveles más altos o iguales al percentil 90 para edad, sexo y talla. Las razones de prevalencia crudas (RPcrudas) y ajustadas (RPajustadas) y los respectivos intervalos de confianza del 95% (IC del 95%) se estimaron mediante regresión logística múltiple. La cesárea ocurrió en el 46,5%, las prevalencias de presión arterial sistólica (PAS) y diastólica (PAD) altas fueron el 17,2% y el 5,6%, respectivamente. El exceso de peso se presentó en el 28,6% de los niños. La mayor prevalencia de PAS alta se observó entre los niños nacidos por cesárea (61%) en comparación con los nacidos por vía vaginal (RPcruda: 1,51; IC95%: 1,07-2,14; RPajustada: 1,61; IC95%: 1,05-2,46). La edad materna al nacimiento del niño fue un factor de interacción en la principal asociación, así, los niños nacidos por vía vaginal tuvieron una mayor prevalencia de PAS elevada en comparación con los nacidos por cesárea. El parto por cesárea se asoció con un aumento de la PAS a los 6 años de edad.

BACKGROUND: Studies on diabetic foot and its complications involving a significant and representative sample of patients in South American countries are scarce. The main objective of this study was to acquire clinical and epidemiological data on a large cohort of diabetic patients from 19 centers from Brazil and focus on factors that could be associated with the risk of ulcer and amputation. METHODS: This study presents cross sectional, baseline results of the BRAZUPA Study. A total of 1455 patients were included. Parameters recorded included age, gender, ethnicity, diabetes and comorbidity-related records, previous ulcer or amputation, clinical symptomatic score, foot classification and microvascular complications. RESULTS: Patients with ulcer had longer disease duration (17.2 ± 9.9 vs. 13.2 ± 9.4 years; p < 0.001), and poorer glycemic control (HbA1c 9.23 ± 2.03 vs. 8.35 ± 1.99; p < 0.001). Independent risk factors for ulcer were male gender (OR 1.71; 95 % CI 1.2-3.7), smoking (OR 1.78; 95 % CI 1.09-2.89), neuroischemic foot (OR 20.34; 95 % CI 9.31-44.38), region of origin (higher risk for those from developed regions, OR 2.39; 95 % CI 1.47-3.87), presence of retinopathy (OR 1.68; 95 % CI 1.08-2.62) and absence of vibratory sensation (OR 7.95; 95 % CI 4.65-13.59). Risk factors for amputation were male gender (OR 2.12; 95 % CI 1.2-3.73), type 2 diabetes (OR 3.33; 95 % CI 1.01-11.1), foot at risk classification (higher risk for ischemic foot, OR 19.63; 95 % CI 3.43-112.5), hypertension (lower risk, OR 0.3; 95 % CI 0.14-0.63), region of origin (South/Southeast, OR 2.2; 95 % CI 1.1-4.42), previous history of ulcer (OR 9.66; 95 % CI 4.67-19.98) and altered vibratory sensation (OR 3.46; 95 % CI 1.64-7.33). There was no association between either outcome and ethnicity. CONCLUSIONS: Ulcer and amputation rates were high. Age at presentation was low and patients with ulcer presented a higher prevalence of neuropathy compared to ischemic foot at risk. Ischemic disease was more associated with amputations. Ethnical differences were not of great importance in a miscegenated population.
RESUMO
BACKGROUND: The Study of Cardiovascular Risk in Adolescents (Portuguese acronym, "ERICA") is a multicenter, school-based country-wide cross-sectional study funded by the Brazilian Ministry of Health, which aims at estimating the prevalence of cardiovascular risk factors, including those included in the definition of the metabolic syndrome, in a random sample of adolescents aged 12 to 17 years in Brazilian cities with more than 100,000 inhabitants. Approximately 85,000 students were assessed in public and private schools. Brazil is a continental country with a heterogeneous population of 190 million living in its five main geographic regions (North, Northeast, Midwest, South and Southeast). ERICA is a pioneering study that will assess the prevalence rates of cardiovascular risk factors in Brazilian adolescents using a sample with national and regional representativeness. This paper describes the rationale, design and procedures of ERICA. METHODS/DESIGN: Participants answered a self-administered questionnaire using an electronic device, in order to obtain information on demographic and lifestyle characteristics, including physical activity, smoking, alcohol intake, sleeping hours, common mental disorders and reproductive and oral health. Dietary intake was assessed using a 24-hour dietary recall. Anthropometric measures (weight, height and waist circumference) and blood pressure were also be measured. Blood was collected from a subsample of approximately 44,000 adolescents for measurements of fasting glucose, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides, glycated hemoglobin and fasting insulin. DISCUSSION: The study findings will be instrumental to the development of public policies aiming at the prevention of obesity, atherosclerotic diseases and diabetes in an adolescent population.
