Health in early adulthood: the contribution of the 1978/79 Ribeirão Preto birth cohort

The increase in non-communicable chronic diseases of adults is due to demographic changes and changes in the risk factors related to physical activity, smoking habits and nutrition. We describe the methodology for the evaluation of persons at 23/25 years of age of a cohort of individuals born in Ribeirão Preto in 1978/79. We present their socioeconomic characteristics and the profile of some risk factors for chronic diseases. A total of 2063 participants were evaluated by means of blood collection, standardized questionnaires, anthropometric and blood pressure measurements, and methacholine bronchoprovocation tests. The sexes were compared by the chi-square test, with alpha = 0.05. Obesity was similar among men and women (12.8 and 11.1 percent); overweight was almost double in men (30.3 vs 17.7 percent). Weight deficit was higher among women than among men (8.6 and 2.6 percent). Women were more sedentary and consumed less alcohol and tobacco. Dietary fat consumption was similar between sexes, with 63 percent consuming large amounts (30 to 39.9 g/day). Metabolic syndrome was twice more frequent among men than women (10.7 vs 4.8 percent), hypertension was six times more frequent (40.9 vs 6.4 percent); altered triglyceride (16.1 vs 9.8 percent) and LDL proportions (5.4 vs 2.7 percent) were also higher in men, while women had a higher percentage of low HDL (44.7 vs 39.5 percent). Asthma and bronchial hyper-responsiveness were 1.7 and 1.5 times more frequent, respectively, among women. The high prevalence of some risk factors for chronic diseases among young adults supports the need for investments in their prevention.

Resposta a administracao de corticosteroide em pacientes portadores de doenca pulmonar obstrutiva cronica e asma / Response to administration of corticosteroids in patients with chronic obstructive lung disease and asthma

Realizamos estudo espirometrico avaliando a resposta a adminisatracao de 200 mcg de salbutamol via inalatoria, antes e apos a administracao diaria de 8 mg de triancinolona, via oral, por um periodo de em media duas semanas, em 21 pacientes portadores de doenca pulmonar obstrutiva cronica (DPOC) ou asma. Onze pacientes responderam com aumento significante da CVF ou "VEF IND. 1" ou "FEF IND. 25-75 por cento", apos o uso de corticosteroides. Dez pacientes nao responderam. Houve em media aumento significante da CVF e "VEF IND. 1" (p < 0,01) e do "FEF IND. 25-75 por cento" (p < 0,05), apos o uso de corticosteroide. Nao houve diferenca significante entre os respondedores e nao respondedores ao uso de corticosteroide quanto a idade, a CVF, "VEF IND. 1" e "FEF IND. 25-75 por cento" iniciais (percentagem do predito). O grupo dos pacientes respondedores ao uso de corticosteroide, tambem respondeu ao uso do broncodilatador, quanto ao "FEF IND. 25-75 por cento", deferindo significativamente do grupo dos nao respondedores (p < 0,02). Houve correlacao negativa significante entre a intensidade da resposta ao corticosteroide e ao broncodilatador, avaliada pelo delta "FEF IND. 25-75 por cento" (p < 0,05). A administracao do corticoide nao modificou a resposta ao broncodilatador.
