Summary: | Under-reporting of self-reported energy intake (EI) has been described
in female, overweight, and pregnant subjects but little is known about
its prevalence in severely obese pregnancy. This study aimed to assess
this in severely obese pregnant women (body mass index ≥40 kg/m2
)
who completed a food frequency questionnaire at 28 weeks gestation
for a cohort study of severe obesity in pregnancy, and to compare it to
the prevalence in normal-weight pregnant women. Estimated energy
requirement (EER) was calculated using Dietary Reference Intakes equations
(Institute of Medicine, 2002) with adjustment for pregnancy
requirements. EI : EER ratio was used to categorize each person as under-, adequate or over-reporter by using published cut off-points
(Nowicki et al., 2011). 98 obese and 68 lean pregnant women were
included. Median EI : EER ratio was lower in obese than in lean (0.72
vs 0.95, p < 0.001), indicating higher prevalence of under-reporting in
obese as compared to in lean (49.0% vs 14.7%). Over-reporting was
lower in obese (7.1%) than in lean (13.2%).In both groups, underreporters
reported lower intakes of fats, dietary cholesterol and sugars
but higher of dietary fi bre, vitamin C, iron, calcium and folic acid (all
p < 0.05), compared to adequate or over-reporters. In conclusion, there
is a higher prevalence of energy under-reporting in obese, compared to
in lean pregnant women in this study. Statistical adjustment of energy
on nutrient intakes may reduce (but not fully remove) the infl uence of
energy misreporting. Data should still be interpreted with caution,
particularly in identifying dietary insufficiency. |
