“…Thirty-eight per cent of the interviewees (n 5 893) agreed to participate in the biochemical analysis of nutritional status. Of these persons, blood samples from a subsample of 378 individuals were randomly selected for determining levels of b-carotene, retinol and a-tocopherol [15][16][17] .…”

“…ENCAT 1992-93 survey In 1992-93, samples were obtained and processed by a mobile team at health centres that had been selected among those available in municipalities that were included in the sample. Blood samples were collected between 8 and 10 a.m. in 12-hour fasting conditions [15][16][17] .…”

“…Given that commercial quality control teams did not exist at the time samples were collected, blood bank donor samples were used as control and it was determined as a coefficient of variation. The coefficients of variation (CV) intra and inter-assay ranged from 6% to 9.9% for b-carotene, from 4.5% to 7.3% for retinol and from 3.5% to 8.4% for a-tocopherol 17 .…”

“…In 1992-93, the Catalan government developed an Evaluation of Nutritional Status of the Catalan population, which included a biochemical assessment [15][16][17] . Blood lipid analysis included total cholesterol (TC), low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL) and serum triglycerides (TG).…”

Objective: The purpose of this study was to assess the 10-year trend in lipid and antioxidant vitamin levels in the Catalan population from 1992 to 2003. Design: Two cross-sectional surveys were carried out in Catalonia, Spain, during 1992-93 and 2002-03. A subsample of the individuals participating in the surveys agreed to undergo a biochemical evaluation. Subjects: Eight hundred and eighty individuals (393 males and 487 females) in the 1992-93 nutritional survey and 429 individuals (205 males and 224 females) in the 2002-03 nutritional and health survey. The subjects' ages ranged from 18 to 74 years. Results: Mean total cholesterol decreased from 5.3 to 5.1 mmol l 21 (P , 0.005), and the prevalence of hypercholesterolaemia decreased, especially in males (from 23% to 10% in males from 50 to 64 years old, P , 0.05). Mean cholesterol high-density lipoprotein (HDL) values decreased in the entire sample (from 1.4 to 1.3 mmol l 21 , P , 0.001) and there was an increase in the percentage of population with low values of HDL (from 10% to 19%, P , 0.001). An increase in the percentage of the population with values of a-tocopherol at marginal risk levels (from 6% to 9%) and with low values of b-carotene (from 59% to 66%) was observed. The mean values for retinol increased in both males (from 1.99 to 2.44 mmmol l 21 , P , 0.001) and females (from 1.69 to 2.29, P , 0.001). Conclusion: Although there was a decrease in the percentage of population with hypercholesterolaemia, the decrease in HDL cholesterol worsened the lipid profile of the Catalan population. The increase in the values of some antioxidant vitamins did not affect the entire population since an increase in the number of individuals with marginal values was observed.
