Factors associated with overweight and central adiposity in urban workers covered by the Workers Food Program of the Brazilian Amazon Region.

OBJECTIVE: To investigate factors associated with overweight and abdominal obesity in male and female workers. METHODS: This is a cross-sectional population-based study. A representative sample of 1,054 workers ranging from 18 to 74 years of age, selected among individuals covered by the Workers´ Food Program living in the Metropolitan region of Belém, Northern Brazil. Health-related behavior and anthropometry were assessed. Fasting blood samples were collected. RESULTS: Overweight prevalence was 38.0% among women and 50.4% among men. Among overweight subjects, there were 6.1% obese women and 10.7% obese men. Multivariate analysis was used to identify social behavior and clinical-biochemical factors associated with increased body adiposity (BMI > 25 kg/m² and increased waist circumference: > 80 cm for women and > 94 cm for men). Variables positively and significantly associated with overweight and abdominal obesity in men according to prevalence ratio (PR) values were: age (1.02), high family income (1.05), smoking (1.36), hypertension (systolic blood pressure, 1.41; diastolic blood pressure, 1.85) and hypertriglyceridemia (2.29). In women, the PR of increased body adiposity was associated with: age (1.02), alcohol intake (1.42), hypertriglyceridemia (1.44), diastolic blood pressure (1.65) and hyperglycemia (1.71). CONCLUSIONS: The association of overweight and abdominal obesity with social behavior variables should be corrected with preventive and educational measures. Furthermore, association of overweight and abdominal obesity with clinical and biochemical variables places the urban workers from the Amazon region assisted by the Workers´ Food Program at a possible risk for morbidity and mortality from increased body adiposity.

OBJETIVO: Investigar os fatores associados ao sobrepeso e a obesidade abdominal em trabalhadores de ambos os sexos. MÉTODO: Estudo transversal de base populacional, de uma amostra representativa de 1054 trabalhadores, com idade entre 18 e 74 anos, assistidos pelo Programa de Alimentação do Trabalhador na região metropolitana de Belém do Pará, na região norte do Brasil. Parâmetros relacionados à saúde e medidas antropométricas foram obtidas e amostra de sangue foram coletadas. RESULTADOS: A prevalência de sobrepeso foi de 38 por cento nas mulheres e 50,4 por cento nos homens. Dentre os indivíduos com sobrepeso, 6,1 por cento das mulheres eram obesas e 10,7 por cento dos homens tinham obesidade. Análise multivariada foi utilizada para identificar os fatores sociocomportamentais e clínico-bioquímicos associados com o aumento da adiposidade corporal (IMC > 25kg/m2 e circunferência de cintura > 80cm para mulheres e >94cm para homens). As variáveis e a razão de prevalência (PR) associadas ao sobrepeso e adiposidade abdominal nos homens foram: idade (1,02), renda familiar alta (1,05), fumo (1,36), hipertensão (pressão arterial sistólica 1,41 e pressão arterial diastólica 1,85) e hipertrigliceridemia (2,29). Nas mulheres as razões de chance para sobrepeso e adiposidade abdominal foram: idade (1,02), consumo de álcool (1,42), hipertrigliceridemia (1,44), pressão arterial diastólilca (1,65) e hiperglicemia (1,71). CONCLUSÃO: A associação do sobrepeso e obesidade abdominal com parâmetros sociocomportamentais devem ser corrigidos com medidas educativas e preventivas. Além disso, a associação de sobrepeso e obesidade abdominal com parâmetros clínicos e bioquímicos coloca os trabalhadores de Belém do Pará, assistidos pelo Programa de Alimentação do Trabalhador, em possível risco de morbidades e mortalidade precoce pelo aumento de adiposidade corporal.

First isolation of Cryptococcus gattii molecular type VGII and Cryptococcus neoformans molecular type VNI from environmental sources in the city of Belém, Pará, Brazil.

Cryptococcus neoformans and Cryptococcus gattii are important agents of meningoencephalitis in humans in the city of Belém. This clinical data suggests that the region may be a highly endemic area for the pathogenic Cryptococcus species within the state of Pará (PA), Northern Brazil. Preliminary analysis of 11 environmental samples from the city of Belém showed two positive locations, including a hollow of a kassod tree (Senna siamea) colonized simultaneously by C. gattii molecular type VGII and C. neoformans molecular type VNI, and a birdcage in a commercial aviary positive for C. neoformans, molecular type VNI. This is the first evidence of an environmental occurrence of molecular types VNI and VGII in PA.

Flavonóides de Cissus verticillata e a atividade hipoglicemiante do chá de suas folhas

Cissus verticillata, a Vitaceae very used in the traditional medicine in Pará and Minas Gerais State - Brazil, was investigated in order to validate its indication for the hyperglycaemia control. The aqueous extract reduces the normal glycaemia of male white Wistar rats in about 19.5 percent. The hypoglycaemic effect of this extract could be related to the flavonoids found in the preparation. Luteolin, Kaempferol and Luteolin-3'-sulphate could be isolated from the aqueous extract after acid hydrolysis.
