There is a wide acknowledgement of obesity as a relevant clinical entity. Such relevance can be inferred by the huge worldwide amount of research and related health promotion and clinical efforts. Though the evidence sustains some cues for the therapeutic success, the overall long-term effectiveness of obesity treatment tends to be not so satisfactory. Scientific literature is not unequivocal in key areas of nu...

São vários, e ainda mal compreendidos, os factores que contribuem para a obesidade. Em Portugal, há simultaneamente uma elevada prevalência de obesidade e um elevado consumo de bebidas alcoólicas. A associação entre consumo de álcool e obesidade não é clara. Este artigo analisa a associação entre a frequência auto-relatada de consumo de bebidas alcoólicas (vinho, cerveja e bebidas brancas/espirituosas) e a prev...
Sabe-se pouco sobre a prevalência da prática de actividade física em Portugal, estratificada por categorias de índice de massa corporal. O objectivo do presente projecto foi verificar a associação da prática de actividade física como (a) características sociodemográficas e (b) índice de massa corporal. Trata-se de um estudo observacional e transversal. Dados recolhidos entre Janeiro/2003 e Janeiro/2005, por que...

It is indicated in the super--obese who are candidates for bariatric surgery to lose weight and to reduce their high surgical risk. Our aim was to retrospectively evaluate the results of the patients in whom this device was inserted during a three-year period from the beginn...
O uso de valores de peso e altura auto-relatados para cálculo do índice de massa corporal (IMC) é comum na investigação biomédica. Contudo, existe tendência para subestimação do peso e sobreestimação da altura auto-relatados. Destes desvios resulta um IMC auto-relatado subestimado e, consequentemente, estimativas de menor prevalência de pré-obesidade e de obesidade, especialmente entre populações femininas e id...
Obesity is an endemic health problem in most developed countries, requiring serious public health attention. The first Portuguese nationwide representative survey about obesity (with objective anthropometric measurement) was undertaken from 1995 to 1998. This paper presents data coming from the second and most recent nationwide representative study of obesity, with objective measurement of weight, height, waist...
Obesity is a serious health problem in developed countries. Knowledge of reliable and nationwide representative data is a must for any public health action. The dimension of this problem in Portugal was first assessed in 1995–1998. A similar populational survey using objective anthropometric measures is now being conducted (field work started in January 2003). A total of 6411 subjects aged 18– 64 years old have...
