title: Vitamin status of healthy subjects in Burgundy (France).
abstract: A nutrition survey was conducted in Burgundy (France) with a population sample of 337 middle-aged and healthy subjects (157 males and 180 females) recruited at a health examination center in 1985-1986. The status of beta-carotene, thiamin, riboflavin, folate, vitamin B6, B12, C, A, D, and E was assessed by means of 7-day food records and biochemical studies. Results were compared with two other recent nutritional surveys conducted in France: ESVITAF (control group only) and Val de Marne surveys. The dietary information collected for each subject was compared to the 1992 French Recommended Dietary Allowances (FRDA). Dietary vitamin intakes were higher in males than in females. Low vitamin intakes (< 1/2 FRDA) were found in 5% of males and 7% of females for thiamin, in 11% of males and 28% of females for vitamin B6, in 6% of males and 3% of females for vitamin C, in 87% of males and 91% of females for vitamin D, and in 8% of males and 13% of females for vitamin E. No subject had a vitamin intake < 1/2 FRDA for riboflavin, folate, vitamins A and B12. ESVITAF and Val de Marne studies also show low vitamin intakes for vitamin B6, thiamin, riboflavin, vitamins D and E. Biochemical status was examined using erythrocyte enzyme function and blood vitamin levels. The percent of subjects with deficient biochemical values was high for vitamin B6 (15% of all males and 20% of all females), and vitamin D (13% of all males, and 15% of all females). With regard to thiamin, riboflavin, vitamin C, folate, vitamin B12, vitamin A, and vitamin E, < 5% of subjects had values in the range of major vitamin deficiency. However, in both genders, except for vitamin C and vitamin A (only for females), low values corresponding to a moderate risk of vitamin deficiency was high for most vitamins. The incidence of a severe deficient vitamin status for thiamin and riboflavin was higher in Val de Marne than in Burgundy, or ESVITAF. In Val de Marne, the probability of a moderate risk of vitamin deficiency was high for thiamin, riboflavin, vitamin B6, vitamin A and vitamin E. Our results (as other studies performed in France and in other industrialized countries) raise the issue of the health significance of marginally deficient vitamin status.
