Results show no significant difference between the age-energy intake profiles of men and women. The decomposition of this intake between carbohydrates, lipids (i.e., fats) and proteins shows a lack of balance in the diet in Czechoslovakia, but significant progress toward a more balanced diet has taken place over the period. Finally, household characteristics such as the woman's level of education, or household income, have at most a marginal impact on these profiles.ennutritionhousehold budget datademand analysispenalized least squaresjournal article
