OBJETIVO: Avaliar a densidade energética da dieta de adultos do município de São Paulo e fatores associados. SUJEITOS E MÉTODOS: Participantes do estudo ISA-Capital, com amostragem probabilística (n = 710 adultos). O consumo alimentar foi avaliado pelo R24h. As correlações foram investigadas pelo coeficiente de correlação de Pearson. As associações com dados demográficos, socioeconômicos e de estilo de vida foram investigadas por modelos de regressão multivariados. RESULTADOS: A densidade energética média foi 1,98 kcal/g (IC95% [1,94; 2,01]) e correlacionou-se positivamente com a ingestão de energia, gordura, carboidrato, colesterol, gordura saturada, sacarose, gordura trans e açúcar adicionado e negativamente com fibras. Apenas idade e hábito de fumar apresentaram associação com a densidade energética. CONCLUSÕES: Os valores elevados da densidade energética da dieta e a relação demonstrada com outros constituintes nutricionais denotam má qualidade da dieta nessa população, o que pode estar contribuindo para crescentes taxas de excesso de peso.

OBJECTIVE: To evaluate dietary energy density in adults living in Sao Paulo and associated factors. SUBJECTS AND METHODS: Subjects were participants of ISA-Capital study, which was carried out with probabilistic sampling (n = 710 adults). Food consumption was assessed by R24h. Correlations with dietary constituents were evaluated using Pearson's correlation coefficient. Associations with demographic, socioeconomic and lifestyle data were investigated by multivariate regression models. RESULTS: The average energy density was 1.98 kcal/g (95% CI [1.94, 2.01]). It was positively correlated with energy, fat, carbohydrate, cholesterol, saturated fat, sucrose, trans fat and added sugar intake; and negatively correlated with fiber intake. Only age and smoking were associated with energy density. CONCLUSIONS: High values of energy density and the relationship determined with other nutritional constituents denote the poor quality of the diet in this population, which may be contributing to the rising rates of overweight.

OBJECTIVE: To describe the lipid profile and to verify its relationship with cardiovascular disease risk factors in students at a public university in São Paulo. METHODS: After obtaining clinical, anthropomorphic, and lipid profile data from 118 students, variables of the lipid profile were related to other risk factors. RESULTS: The mean age of the students was 20.3 years (SD=1.5). The risk of cardiovascular disease was characterized by a positive family history of ischemic heart disease in 38.9%; sedentariness in 35.6%; limiting and increased total and LDL-C cholesterol levels in 17.7% and 10.2%, respectively; decreased HDL-C levels in 11.1%; increased triglyceride levels in 11.1%; body mass index >25 in 8.5%, and smoking in 6.7% of the subjects. Students' diet was found to be inadequate regarding protein, total fat, saturated fat, sodium, and fiber contents. A statistically significant association between cholesterol and contraceptive use, between HDL-C and contraceptive use, age and percent body fat, and triglycerides and percent lean weight was observed. CONCLUSION: A high prevalence of some risk factors of cardiovascular disease as well as the association between these factors with altered lipid profiles was observed in the young population studied.
