Energy intake and physical activity during pregnancy in relation to maternal fat accretion and infant birthweight.
During the second pregnancy of 56 Swedish women resulting in a term birth, energy intake and physical activity were measured for 3 days at weeks 17 and 33. The values were related to maternal lean body mass, pregnancy weight gain, maternal fat accretion and infant birthweight by multiple linear regression analyses. A significant regression coefficient was found for energy intake at week 17 on maternal fat accretion. Energy intake was not significantly correlated with infant birthweight, not even when physical activity and maternal lean body mass were taken into account. Thus in a well-nourished Swedish population, energy intake is positively related to maternal fat accretion but not to the birthweight of term infants.
