1Based on WHO's dietary goals [19] as proportion of total energy intake. Risk for excessive intakes of TF, SFA, PUFA and n-6 were set at >30%, ≥10%, >10% and >8%, respectively. Low intakes of PUFA, n-6 and n-3 were set at below 6%, 5% and 1 %E, respectively.

2Ratio n-6:n-3 >8 was defined as inadequate

3For cholesterol, intakes equal or above 300 mg/day were considered as risk for excessive intakes.

4Differences, between SES groups, in prevalence of the risk for inadequate intakes of the fat and fatty acids listed in the table, were tested, for the total sample and within each gender group, with logistic regression models, with adjustment for energy intake in the case of cholesterol. OR = odds ratio; CI = confidence interval.
