The nutritional status of people living with HIV/AIDS (PLWHA) is related to morbidity and mortality and its monitoring is important in the maintenance of the health status. This is a cross-sectional study carried out in Brazilian National Health System in the Municipality of São Paulo. It describes anthropometrical characteristics: weight and height; indices of weight for height (W/H), height for age (H/A), body mass index for age (BMI/A) and Z score for height and weight. The study includes 772 participants from all ages: children, adolescents, adults and elderly. The graphical analysis shows that in under-5s and in the 5 to 19 years old group, the W/H, the H/A and the BMI/A curves are similar to the reference population with an exception in the H/A for 5 to 19 years old group which is left-shifted (mean Z = -0.66). In the case of adults, graphics for the study population show median weight apparently lower than in the reference population for most age groups in the case of men, and when age is greater in women. The proportion of people over 20 years old with AIDS on anti-retroviral therapy is lower when coinfection is present (p < 0.001). The findings of the study showed that, for children and adolescents with HIV/AIDS, the average weight and height are lower than the values for non infected population. For adults and elderly, the weight average is lower than the reference population with a worsening among coinfected patients. This underscores the need to direct more effort in nutritional actions thus helping enhance the health status of this group.

Introduction: Nutrition currently plays a key role in the treatment of people living with HIV/AIDS (PLHA), especially in the case of metabolic alterations due to highly active antiretroviral therapy (HAART), which could be related to cardiovascular diseases (CD)., Objective: to describe the nutritional and clinical status, and the quality of diet of PLHA., Methods: It is a cross-sectional study involving a network of ambulatory care facilities for PLHA in the city of São Paulo, Brazil. Patients, in use of HAART or not, were selected from December 2004 to may 2006, through routine clinic visits. We collected: socio-demographic, clinical, biochemical, anthropometric measures and dietary data. Diet quality was evaluated according to a "protecting" or "non-protecting" pattern of consumption scores for CD., Results: The sample had 238 patients on HAART and 76 without treatment. Mean serum levels of total cholesterol, triglycerides and glucose were higher in the HAART group (p < 0.001). The majority of patients of both the treated and untreated group were eutrophic with a mean body mass index (BMI) of 24.4 (± 4.3) kg/m² and 24.3 (± 3.5), respectively. The waist-hip ratio was higher among men on HAART (0.90 ± 0.06 versus 0.87 ± 0.05) (p < 0.001). The HAART group showed a mean food pattern score indicating a higher consumption of "non-protecting" foods for CD (p = 0.001)., Conclusion: The results showed undesired nutritional and metabolic conditions among patients on HAART associated with CD. It is necessary to manage health intervention programs for PLHA in order to control cardiovascular risk factors before final outcomes.
