Autores: Yáñez,E.; Silva,C.; Nieto,K.; Barbieri,M.A.; Martínez,G.
A work of gathering historical fishing (catch, fishing effort, CPUE, characteristics and operation of purseiner fleet) and satellite (NOAA, SeaStar and SeaWind) database of northern Chile, and fishing and oceanographic in situ sampling for validation purpose is made. With this information and the use of geographical information system (GIS) the distribution of pelagic resources and the associated environmental conditions (sea surface temperature, thermal gradients, chlorophyll concentration and wind fields) are analysed in order to develop a probable fishing ground (PFG) index prediction model. A PFG model of anchovy (Engraulins ringens) is operative for the northern Chile. The impact of the use of PFG charts was evaluated analyzing the operational...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Tomé,F.S.; Cardoso,V.C.; Barbieri,M.A.; Silva,A.A.M. da; Simões,V.M.F.; Garcia,C.A.; Bettiol,H.
In the late 1980's child malnutrition was still prevalent in Brazil, and child obesity was beginning to rise in the richest regions of the country. To assess the extent of the nutritional transition during the period and the influence of birth weight and maternal smoking on the nutritional condition of schoolchildren, we estimated the prevalence of excess weight and malnutrition in a cohort of Brazilian schoolchildren from 1987 to 1989. We calculated the body mass index (BMI) of 8- to 10-year-old schoolchildren born in Ribeirão Preto in 1978/79. We considered children with a BMI &lt;5th percentile (P5) to be malnourished, children with P5³BMI&lt;P85 to be thin and normal, and children with BMI ³P85 to be overweight. We evaluated the association of these...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Figueiredo,F.P.; Silva,A.A.M.; Bettiol,H.; Barbieri,M.A.; Batista,R.F.L.; Lamy Filho,F.; Silva,R.A.; Aragão,V.M.F.
The association between socioeconomic position (SEP) and serum lipids has been little studied and the results have been controversial. A total of 2063 young adults born in 1978/79 were evaluated at 23-25 years of age in the fourth follow-up of a cohort study carried out in Ribeirão Preto, SP, Brazil, corresponding to 31.8% of the original sample. Total serum cholesterol (TC), triglycerides, high-density cholesterol (HDL cholesterol) and low-density cholesterol (LDL cholesterol) were analyzed according to SEP at birth and during young adulthood. SEP was classified into tertiles of family income and a cumulative score of socioeconomic disadvantage was created. TC was 11.85 mg/100 mL lower among men of lower SEP in childhood (P &lt; 0.01) but no difference...

Autores: Coimbra,L.C.; Figueiredo,F.P.; Silva,A.A.M.; Barbieri,M.A.; Bettiol,H.; Caldas,A.J.M.; Mochel,E.G.; Ribeiro,V.S.
Data for two birth cohorts from two Brazilian municipalities, Ribeirão Preto in 1994 and São Luís in 1997/1998, were used to identify and compare factors associated with inadequate utilization of prenatal care and to identify factors capable of explaining the differences observed between the two cities. Prenatal care was defined as adequate or inadequate according to the recommendations of the Brazilian Ministry of Health. The chi-square test and Poisson regression were used to compare differences in the inadequacy of prenatal care utilization. The percentage of inadequacy was higher in São Luís (34.6%) than in Ribeirão Preto (16.9%). Practically the same variables were associated with inadequacy in both cities. Puerperae with lower educational level,...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Ribeiro,V.S.; Figueiredo,F.P.; Silva,A.A.M.; Bettiol,H.; Batista,R.F.L.; Coimbra,L.C.; Lamy,Z.C.; Barbieri,M.A.
The objective of the present study was to investigate factors associated with cesarean sections in two cities located in different regions of Brazil and to determine factors that explain the higher cesarean section rate in the more developed city, Ribeirão Preto, compared to the less developed one, São Luís. Data from two cohort studies comprising 2846 women in Ribeirão Preto in 1994, and 2443 women in São Luís in 1997/1998 were used. Adjusted and non-adjusted risk estimates were calculated using a Poisson regression model. The cesarean section rate was 33.7% in São Luís and 50.8% in Ribeirão Preto. Adjusted analysis in a joint sequential model revealed a 51% higher risk of cesarean section in Ribeirão Preto compared to São Luís (prevalence rate ratio...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Silva,L.M.; Silva,R.A.; Silva,A.A.M.; Bettiol,H.; Barbieri,M.A.
Few studies are available about racial inequalities in perinatal health in Brazil and little is known about whether the existing inequality is due to socioeconomic factors or to racial discrimination per se. Data regarding the Ribeirão Preto birth cohort, Brazil, whose mothers were interviewed from June 1, 1978 to May 31, 1979 were used to answer these questions. The perinatal factors were obtained from the birth questionnaire and the ethnic data were obtained from 2063 participants asked about self-reported skin color at early adulthood (23-25 years of age) in 2002/2004. Mothers of mulatto and black children had higher rates of low schooling (£4 years, 27.2 and 38.0%) and lower family income (£1 minimum wage, 28.6 and 30.4%). Mothers aged less than 20...

Autores: Goldani,M.Z.; Haeffner,L.S.B.; Agranonik,M.; Barbieri,M.A.; Bettiol,H.; Silva,A.A.M.
The association between early life factors and body mass index (BMI) in adulthood has been demonstrated in developed countries. The aim of the present study was to assess the influence of early life factors (birth weight, gestational age, maternal smoking, and social class) on BMI in young adulthood with adjustment for adult socioeconomic position. A cohort study was carried out in 1978/79 with 6827 mother-child pairs from Ribeirão Preto city, located in the most developed economic area of the country. Biological, economic and social variables and newborn anthropometric measurements were obtained shortly after delivery. In 1996, 1189 males from this cohort, 34.3% of the original male population, were submitted to anthropometric measurements and were asked...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Ribeiro,V.S.; Figueiredo,F.P.; Silva,A.A.M.; Batista,R.L.F.; Barbieri,M.A.; Lamy Filho,F.; Alves,M.T.S.S.B.; Santos,A.M.; Bettiol,H.
The prevalence of smoking during pregnancy in Ribeirão Preto, a rich Brazilian city, was significantly higher (21.4%) than in São Luís (5.9%), a less developed city. To assess which variables explain the difference in prevalence of smoking during pregnancy, data from two birth cohorts were used, including 2846 puerperae from Ribeirão Preto, in 1994, and 2443 puerperae from São Luís, in 1997/98. In multivariable analysis, risk of maternal smoking during pregnancy was higher in São Luís for mothers living in a household with five or more persons (OR = 1.72, 95%CI = 1.12-2.64), aged 35 years or older (OR = 1.98, 95%CI = 0.99-3.96), who had five or more children (OR = 2.10, 95%CI = 1.16-3.81), and whose companion smoked (OR = 2.20, 95%CI = 1.52-3.18).

Do intrauterine growth restriction and overweight at primary school age increase the risk of elevated body mass index in young adults?
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Bettiol,H.; Sabbag Filho,D.; Haeffner,L.S.B.; Barbieri,M.A.; Silva,A.A.M.; Portela,A.; Silveira,P.; Goldani,M.Z.
Obesity is one of the rising public health problems characterized as a risk factor for many chronic diseases in adulthood. Early life events such as intrauterine growth restriction, as well as life style, are associated with an increased prevalence of this disease. The present study was performed to determine if intrauterine growth restriction interacts with overweight at primary school age to affect body mass index (BMI) in young adults. From June 1, 1978 to May 31, 1979, 6827 singleton liveborns from Ribeirão Preto, São Paulo State, Brazil, corresponding to 98% of all births at the 8 maternity hospitals, were examined and their mothers were interviewed. Samples from the initial cohort were examined again at primary school age (8 to 11 years of age) and...

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%); overweight was...

Factors associated with infant and adolescent mortality
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Oliveira,Z.A.R.; Bettiol,H.; Gutierrez,M.R.P.; Silva,A.A.M.; Barbieri,M.A.
Few studies have described factors associated with infant and adolescent mortality since birth. We report here mortality during a 20-year period in a birth cohort from Ribeirão Preto in order to identify birth variables that influenced mortality among infants and children between 10 and 19 years of age, the main causes of death, and the influence of social inequality at birth on death. Mothers were interviewed shortly after delivery. Social, biological and demographic information was collected, and mortality up to 19 years of age was investigated in registry systems. Of the 6748 liveborn singletons born in the municipality from 1978 to 1979, 343 died before or when 19 years of age were completed. Most of the cohort mortality (74.9%) occurred during the...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Lamy Filho,F.; Assunção Júnior,A.N.; Silva,A.A.M.; Lamy,Z.C.; Barbieri,M.A.; Bettiol,H.
The objective of the present study was to estimate and compare social inequality in terms of three indicators, i.e., low birth weight (LBW), preterm birth (PTB) and small for gestational age (SGA) birth, in three birth cohorts. Two cohorts were from the city of Ribeirão Preto, where data were collected for all 6748 live born singletons in 1978/79 and for one third of live born singletons (2846) in 1994. The third cohort consisted of 2443 singletons born in São Luís over a period of one year (1997/98). In Ribeirão Preto, LBW and PTB rates increased in all social strata from 1978/79 to 1994. Social inequalities regarding LBW and PTB disappeared since the increase in these rates was more accelerated in the groups with higher educational level. The percentage...
