abstract = {Physical fitness is a strong marker of health, but objective fitness measurements are not always
feasible. The International FItness Scale (IFIS) for self-reported fitness is a simple-to-use tool with
demonstrated validity and reliability; however, validation in pregnancy needs to be confirmed.
Also, its association with cardiometabolic health in pregnant women is unknown. Hence, we
examined (1) the validity of the IFIS with objectively measured fitness, and (2) the associations of
self-reported versus objectively measured cardiorespiratory fitness (CRF) and muscular strength with
cardiometabolic risk factors in early pregnancy. Women (n = 303) from the HealthyMoms trial were
measured at gestational week 14 for: CRF (6-min walk test); upper-body muscular strength (handgrip
strength test); self-reported fitness (IFIS), body composition (air-displacement plethysmography);
blood pressure and metabolic parameters (lipids, glucose, insulin). Higher self-reported fitness was
associated with better measured fitness (ANOVA overall p < 0.01 for all fitness types), indicating the
usefulness of the IFIS in pregnancy. Furthermore, higher self-reported overall fitness and CRF were
associated with lower cardiometabolic risk scores (ANOVA p < 0.001), with similar results shown for
measured CRF (ANOVA p < 0.001). The findings suggest that IFIS could be useful to stratify pregnant
women in appropriate fitness levels on a population-based level where objective measurement is not
possible.},
