As. Anderson et al., NUTRITION KNOWLEDGE, ATTITUDE TO HEALTHIER EATING AND DIETARY-INTAKE IN PREGNANT COMPARED TO NONPREGNANT WOMEN, Journal of human nutrition and dietetics, 6(4), 1993, pp. 335-353
The nutrition knowledge, attitudes and dietary behaviour of a group of
women in early pregnancy and a group of non-pregnant women were compa
red to ascertain the impact of pregnancy on diet. The main results ind
icate that pregnant women do eat differently from non-pregnant women,
in particular intakes of zinc and vitamin C, and the nutrient density
of protein and sodium were higher and intakes of alcohol lower in the
pregnancy group compared to the non-pregnant group. The group of pregn
ant women also tended to consume more milk and fruit and less chocolat
e, cakes and pastries compared to non-pregnant women. However, the dif
ferences in dietary behaviour between the two groups could not be acco
unted for by nutrition knowledge (the same in both groups). Higher sco
res for beliefs about 'healthier eating' and subjective norm were foun
d in the early pregnancy group which might account for some of the obs
erved differences between the groups. In addition, it is concluded tha
t 'historicity' or a basic 'knowledge' of which foods to consume is pr
evalent in early pregnancy.
