- ItemAcesso aberto (Open Access)Biometria ocular, erro refrativo e sua relação com a estatura, idade, sexo e escolaridade em adultos brasileiros(Conselho Brasileiro de Oftalmologia, 2007-06-01) Pereira, Graziela Campanelli [UNIFESP]; Allemann, Norma [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To assess ocular biometric parameters and refractive error in Brazilian adults and their relationship with height, age, gender and years of formal education. METHODS: Cross-sectional study that assessed 173 subjects by keratometry, echobiometry, refraction and measurement of body height. The statistical analysis was performed using Pearson's coefficient and a regression model was constructed. RESULTS: The correlations found were: each 10 cm - increase in height was related to a 0.32 mm longer axial length, 0.07 mm deeper anterior chamber, 0.26 mm deeper vitreous chamber and 0.50 D flatter keratometry. Each 10-year increase in age, related to a 0.15 mm smaller axial length, 0.25 mm thicker lens, 0.21 mm shallower vitreous chamber and 0.23 D more positive spherical equivalent. Each 10-year increase in education related to a 0.74 D more negative spherical equivalent. Gender did not influence the analyzed biometric parameters. Equations referring to biometric parameters and spherical equivalent were formulated. CONCLUSIONS: Positive correlations were found between: axial length and height; anterior chamber and vitreous cavity depth with height; lens thickness with age; keratometry with height; and spherical equivalent with age. Negative correlations were found between: anterior chamber and vitreous cavity depth with age; spherical equivalent and years of formal education.
- ItemAcesso aberto (Open Access)Estudo sobre nascidos vivos em maternidades: 1. Peso ao nascer, sexo, tipo de nascimento e filiação previdenciária das mães(Faculdade de Saúde Pública da Universidade de São Paulo, 1988-12-01) Souza, Maria de Lourdes R. de; Tanaka, Ana Cristina D'Andretta; Siqueira, Arnaldo Augusto Franco de; Santana, Renato Martins [UNIFESP]; Universidade Federal de Santa Catarina Centro de Ciências da Saúde Departamento de Saúde Pública; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)Birthweight is the result of many factors (organic, psychological, social) acting on the genetic potential of the fetus. Consequently, its distribution is different according to the characteristics of the population. In this paper the authors studied the weight at birth of live newborns (from 1978 to 1979) in the two big maternity hospitals, in Florianópolis, responsible for 90% of all births in the area, by sex, litter size and mother's health security. The authors verified that the mean birthweight of the 18,491 live newborns was 3,347.6gr. In that population 5.3% of the newborns were low birthweight infants, and 11.1% weighed 4,000gr or more. Male newborns weighed significantly more than female babies, and the same difference occurred between single and multiple births. The relationship between the newborn's birthweight and the kind of health security the mother had showed that the mothers who didn't pay any kind of health security had babies with lower birthweight than those of the mothers who subscribed to some health security scheme. The data showed that this population has a low incidence of low birthweight babies, with a distribution similar to that observed in developed countries.
- ItemAcesso aberto (Open Access)Gender differences in the sleep habits of 11-13 year olds(Associação Brasileira de Psiquiatria - ABP, 2009-12-01) Natal, Cezar Laerte; Lourenço, Tânia Jordana; Silva, Luana A.; Boscolo, Rita Aurélia [UNIFESP]; Silva, Andressa [UNIFESP]; Tufik, Sergio [UNIFESP]; Mello, Marco Tulio de [UNIFESP]; Faculdades COC; Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: Sleep plays an important role in the physical and emotional development of adolescents. The aim of this study was to examine gender differences in sleep habits in a sample of 11-13 year olds. METHOD: The study was carried out in the city of Patos de Minas, Brazil. The study cohort was composed of 200 students (96 boys and 104 girls) attending (in the morning or in the afternoon) the 5th, 6th or 7th grades, with ages ranging from 11 to 13 years. A Sleep Questionnaire developed at the Federal University of São Paulo was used in order to evaluate student sleep habits and schedules, as well as the overall quality of sleep. RESULTS: For the period between Friday night and Sunday morning, girls displayed longer sleep duration than did boys. During the week, students attending only afternoon classes woke up later than did students attending only morning classes. In addition, morning-class students showed more adverse effects on sleep, including irregular sleep/wakefulness circadian rhythms, when compared with afternoon-class students. CONCLUSION: Sleep habits are affected by gender and school schedule.
- ItemAcesso aberto (Open Access)Localização do carcinoma pulmonar em relação ao vício tabágico e ao sexo(Sociedade Brasileira de Pneumologia e Tisiologia, 2006-12-01) Jamnik, Sergio [UNIFESP]; Uehara, Cesar [UNIFESP]; Silva, Vilmer Vieira da [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: To analyze the locations of lung carcinomas in relation to patient gender and smoking status. METHODS: In order to test the hypothesis that lung carcinoma location (upper or lower lobe; left or right side) is correlated with smoking status and gender, we conducted a retrospective study of 697 patients with bronchogenic carcinoma treated at the Pulmonology-Oncology Outpatient Clinic of the Federal University of São Paulo. RESULTS: We found that the bronchogenic carcinomas occurring in smokers were more frequently located in the upper lobes, whereas those occurring in nonsmokers were more frequently located in the lower lobes. In women, the neoplasms were more often seen in the lower lobes, especially in nonsmokers. Based on the available data, there were no differences in terms of the side affected (left or right). CONCLUSION: Overall, bronchogenic carcinomas are predominantly found in the upper lobes. However, in nonsmokers, they occur more frequently in the lower lobes. In females, bronchogenic carcinomas present a tendency to occur more often in the lower lobes.
