“…This is in line with the findings of two papers of the research group of De Lorenzo, in which they reported a moderate but significant increase of ICW during the third trimester [4,14]. They explained a slight increase of ICW at the end of gestation by the water-filling need of the breast tissue and the inferior pelvis in order to guarantee the correct course of labour, delivery and puerperium [14].…”

“…The increasing fluid parameters during an uncomplicated pregnancy found in this study, is in line with different other studies [4,[13][14][15]. The slight decrease of ECW at earlier gestation till 14 weeks as reported by Larciprete et al could not be confirmed in our study [14].…”

“…For this, a large prospective clinical trial is needed. The increased TBW in LPE in this study is in concordance with the report of Levario-Carrillo et al [6], but inconsistent with the results reported by Valensise et al [4]. The latter studied patients with uncomplicated pregnancies and gestational hypertension and found a significantly lower TBW, ECW and ICW in the hypertensive group (TBW: 17.5 AE 3.4L versus 44.4 AE 7.2L for UP and GH respectively).…”

“…The symptoms of preeclampsia like plain oedema, hypertension and oliguria suggest that total body water (TBW) is different in preeclamptic patients compared to uncomplicated pregnancies. However, conclusions regarding body composition, and TBW in particular, are still inconsistent in literature [2][3][4]. Nevertheless, changes in TBW as part of the total body composition is of potential interest to clinicians as abnormal fluid adaptation might give rise to maternal and fetal pathologies such as intrauterine growth restriction [5] or hypertensive gestational complications [6].…”

A B S T R A C TObjectives: Body fluid composition changes during the course of pregnancy and there is evidence to suggest that these changes are different in uncomplicated pregnancies compared to hypertensive pregnancies. The aim of this study was to evaluate the changes in maternal body fluid composition during the course of an uncomplicated pregnancy and to assess differences in uncomplicated pregnancies versus hypertensive pregnancies by using a bio-impedance analysis technique. Study design: Body fluid composition of each patient was assessed using a multiple frequency bioelectrical impedance analyser. Measurements were performed in 276 uncomplicated pregnancies, 34 patients with gestational hypertension, 35 with late onset preeclampsia and 11 with early onset preeclampsia. Statistical analysis was performed at nominal level a = 0.05. A longitudinal linear mixed model based analysis was performed for longitudinal evolutions, and ANOVA with a post-hoc Bonferroni was used to identify differences between groups. Results: Measurements showed that total body water (TBW), intracellular (ICW) and extracellular water (ECW) and ECW/ICW significantly increase during the course of pregnancy. Late onset preeclampsia is associated with a higher TBW and ECW as compared to uncomplicated pregnancies, the ECW/ICW ratio is higher in preeclamptic patients compared to uncomplicated pregnancies and gestational hypertension, and ICW is not different between groups. Conclusion: Body fluid composition changes differently during the course of uncomplicated pregnancies versus hypertensive pregnancies.

“…The evaluation of these components and their modifications could be of the utmost importance during pregnancy, since they can vary on an individual basis, thereby affecting GWG to a variable degree. Nowadays, there aren't studies evaluating the BIA during the different trimesters of pregnancy in obese women with the purpose of monitoring the FM and FFM increase, since the most of them namely consider the total body water [29][30][31][32]. Moreover, there are not so many studies evaluating both the adherence to a proper nutrition and the PA in obese pregnant women, namely through respectively FFQ and SWA.…”

Objectives: Human pregnancy is associated with important physiological changes that usually increase energetic requirements. However, great variability exists in the costs and mechanisms required to bear pregnancy. Since body mass (BM) and composition are modified during gestation, it is of great interest to compare the influence of BM on energy expenditure (EE) in pregnant and nonpregnant females.Methods: BM, body composition, and EE of 77 volunteers (35 pregnant and 42 nonpregnant females) were measured. The pregnant volunteers completed two measurement rounds at 28 and 32 gestation weeks. Differences on the measured parameters were sought, and comparison of regression lines was computed to test how BM affected the EE of the volunteers.Results: BM and body composition parameters are significantly higher in pregnant females, but EE is not statistically different. Pregnant females have a larger percentage of fat mass, but lower percentage of fat-free mass (FFM). The EE per kg of FFM is similar in both groups. Comparison of regression lines shows that pregnancy does not change the relationship between BM and EE, but for similar BM pregnant females expend less energy than nonpregnant females. Conclusions: We propose that their larger percentage of passive body tissues is the reason why pregnant females expend less energy than nonpregnant females of similar BM, without changing the scaling of EE on BM. Thus, pregnancy could not be as energetically constraining as usually assumed, with important consequences for human reproductive ecology.

Multifrequency bioelectrical impedance analysis in women with a normal and hypertensive pregnancy

Abstract: Our results show that multifrequency bioelectrical impedance analysis can be used to monitor variations in body water compartments in normal pregnancy and detect gestational hypertension.
