Este estudo teve como objetivos conhecer a distribuição do peso de nascimento das crianças de Campinas (SP) e indicar fatores de risco para baixo peso. Realizou-se estudo transversal no qual foram utilizados dados das 14.444 Declarações de Nascidos Vivos de 2001. A variável dependente foi o peso de nascimento, e as independentes as características maternas, gestacionais, do parto e do recém-nascido. Na avaliação da associação entre variáveis empregou-se teste de qui-quadrado e calculou-se valores de odds ratio brutos (OR) e ajustados (ORaj). A média do peso de nascimento foi 3.142g, variando de 285 a 5.890g; 65,1% das crianças pesaram 3.000g ou mais, 25,7% entre 2.500 e 2.999g e 9,1% menos de 2.500g. Os determinantes para baixo peso em prematuros foram cesariana, gemelaridade, recém-nascidos femininos e os de mulheres com menos de sete consultas de pré-natal. Para crianças a termo os riscos foram gestação dupla, tripla ou mais, filhos de mulheres com mais de 34 anos, das com até sete anos de estudo, com oito a onze e das com menos de sete consultas de pré-natal. A distribuição de peso de nascimento em Campinas foi inadequada e a proporção de baixo peso foi mais que o dobro dos países desenvolvidos. Os recém-nascidos prematuros que nasceram por cesariana, os prematuros e os a termo de gestação múltipla, os femininos, os de mulheres com pré-natal inadequado e os a termo daquelas com maior idade e baixa escolaridade apresentaram maior chance de nascer com baixo peso.

OBJECTIVE: To evaluate the correlation between neck circumference and insulin resistance and components of metabolic syndrome in adolescents with different adiposity levels and pubertal stages, as well as to determine the usefulness of neck circumference to predict insulin resistance in adolescents. METHODS:Cross-sectional study with 388 adolescents of both genders from ten to 19 years old. The adolescents underwent anthropometric and body composition assessment, including neck and waist circumferences, and biochemical evaluation. The pubertal stage was obtained by self-assessment, and the blood pressure, by auscultation. Insulin resistance was evaluated by the Homeostasis Model Assessment-Insulin Resistance. The correlation between two variables was evaluated by partial correlation coefficient adjusted for the percentage of body fat and pubertal stage. The performance of neck circumference to identify insulin resistance was tested by Receiver Operating Characteristic Curve. RESULTS: After the adjustment for percentage body fat and pubertal stage, neck circumference correlated with waist circumference, blood pressure, triglycerides and markers of insulin resistance in both genders. CONCLUSIONS: The results showed that the neck circumference is a useful tool for the detection of insulin resistance and changes in the indicators of metabolic syndrome in adolescents. The easiness of application and low cost of this measure may allow its use in Public Health services.

Gamma interferon, tumor necrosis factor alpha, interleukin-4 (IL-4), and IL-10 levels in supernatants and serum anti-PT IgG levels were determined using enzyme-linked immunosorbent assay (ELISA). The net percentage of CD3؉ blasts in cultures with B. pertussis in the group vaccinated with wP was higher than that in the group vaccinated with the wP low vaccine (medians of 6.2% for the wP vaccine and 3.9% for the wP low vaccine; P ‫؍‬ 0.029). The frequencies of proliferating CD4 ؉ , CD8 ؉ , and ␥␦ ؉ cells, cytokine concentrations in supernatants, and the geometric mean titers of anti-PT IgG were similar for the two vaccination groups. There was a significant difference between the T-cell subpopulations for B. pertussis and PHA cultures, with a higher percentage of ␥␦ ؉ cells in the B. pertussis cultures (P < 0.001). The overall data did suggest that wP vaccination resulted in modestly better specific CD3 ؉ cell proliferation, and ␥␦ ؉ cell expansions were similar with the two vaccines.

; for the Brazilian Metabolic Syndrome Study (BRAMS) Investigators IMPORTANCE The association between short sleep duration and decreased insulin sensitivity in adolescents has been described. However, to our knowledge, no studies have investigated this association measuring insulin sensitivity by the hyperglycemic clamp technique. OBJECTIVES To compare the distributions of parameters of insulin resistance in adolescents with sleep deprivation vs adequate sleep, and to investigate the association between sleep deprivation and insulin sensitivity. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional multicenter study using data from the Brazilian Metabolic Syndrome Study conducted from June 29, 2011, to December 3, 2014, at an obesity outpatient clinic at the University of Campinas and public schools, with a convenience sample of 615 adolescents aged 10 to 19.9 years with a body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) for age and sex at the fifth percentile or higher. A subsample of 81 adolescents underwent the hyperglycemic clamp technique. MAIN OUTCOMES AND MEASURES The self-reported sleep duration was used to classify the population into 2 groups: adolescents with sleep deprivation (<8 hours/night) and adolescents with adequate sleep (Ն8 hours/night). Insulin sensitivity was assessed using the hyperglycemic clamp technique. RESULTS Among the 615 adolescents (56.3% female; median age, 15.9 years [interquartile range, 12.9-17.8 years]) included in the sample, the mean (SD) sleep duration was 7.9 (1.7) hours/night. The adolescents with sleep deprivation (n = 257) compared with those with adequate sleep (n = 358) had a higher median (interquartile range) age (17.

The risk for insufficient birth weight was higher for female newborn, offspring of primiparous women, of women who had inadequate prenatal care and had vaginal delivery.
