SummaryObesity 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 and hip circumferences. Data were collected between January 2003 and January 2005. The survey collected objective body mass index (BMI) values of 8116 participants aged 18-64. Main findings were: 2.4% of the sample had low weight (BMI < 18.5), 39.4% were overweight (BMI between 25.0 and 29.9), and 14.2% obese (BMI Ն 30). Waist circumference measurement showed that 45.6% of the sample suffers increased cardiovascular health risks associated with high waist circumference. The overall overweight/ obesity prevalence increased from 49.6% (in 1995-1998) to 53.6% (in 2003-2005). These data suggest that although obesity was identified as a public health problem one decade ago, action to reduce it does not seem to have been very effective to date. Well-defined public health intervention must be targeted to specific population groups where higher levels of obesity prevalence were found: low socioeconomic level groups and low-education level groups.

SummaryObesity 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 already been measured and their respective body mass indexes (BMIs) calculated. Results from 2003 to 2005 show 38.6% is overweight and 13.8% has obesity. The total of overweight and obesity is 52.4%. In 1995-1998 survey, overweight was 35.2% and obesity was 14.4%. The total was 49.6%. These results suggest an increase of the overweight/obesity (altogether) prevalence in the last 10 years. Actual results show that more than half of the adult sample has excessive weight and 2.4% of the sample has low BMI. Finally, 45.6% of the sample suffers increased health risks because of high waist circumference ( ≥ 80 cm for women; ≥ 94 cm for men). These results highlight the fact that, although obesity was identified as a public health problem one decade ago, action to reduce it does not seem to have been very effective to date.

Higher drug acquisition costs for deferasirox are offset by the avoidance of infusion-related equipment costs. Combined with health benefits derived from an oral mode of administration and improved compliance, deferasirox has a high probability of being a cost-effective intervention compared with deferoxamine.

Sympathectomy provided excellent patient satisfaction and a low incidence of complications. There was no significant difference between the levels of ablation in terms of reflex sweating, although the intensity of this complication decreased when lower levels of blockage, principally at the T4 level, were employed.
