“…The Latin American and Caribbean Scale (ELCSA) was used in Mexico to investigate the relationship between FI and hearing disorders at birth. Two studies [38,39] (5.4%) used the 9-item individually focused food insecurity access scale (IFIAS) that was validated in 2015 in Uganda in a survey of pregnant women [40]. The remaining studies used individual questions to assess FI (Table S1).…”

“…Regarding the way to evaluate FI, some studies (n = 6, 16.3%) considered FI a continuous variable and used mean scores for analysis [13,24,36,38,39,41]. In the others it was considered as a categorical or ordinal.…”

“…Poor dietary quality and/or dietary diversity and/or inadequate nutrient intake was the second most investigated outcome in eight publications (22.2%); this outcome was associated with FI in six of the publications, but in two publications, the authors found no association [14,34]. The relationship between the gestational weight gain and/or inadequate nutritional status of pregnant women was investigated, with or without an examination of pregnancy complications and nutritional consumption outcomes, in four studies (the studies published by Laraia and colleagues [9,45,48] and by Widen et al [39]. The association of anaemia with FI was verified in three studies [9,32,37].…”

“…Another situation that may represent a risk of bias was noted in the study of Widen and colleagues [39] with HIV pregnant women, which demonstrated associations between FI and adverse body composition changes. In their survey, women who did not know their HIV status were excluded.…”

Background: Food insecurity (FI) occurs when people lack secure access to sufficient amounts of safe and nutritious food. FI has been associated with negative effects on human health, including during the prenatal and neonatal periods. The objective of this study is to evaluate the consequences of FI for pregnant women's and newborns' health. Methods: A literature search was performed with three independent researchers based on the PRISMA guidelines; the search covered the period of November 2008 to July 2019 and was conducted in the following databases: the

“…One of the most outstanding applications of bioimpedance in healthcare is the estimation of body composition, which is normally applied to assess the nutritional and hydration status and useful in multiple clinical areas: obstetrics [13], postoperative monitoring [14], critical care [15], pregnancy and lactation [16], gastroenterology [17], nutrition [18], chronic inflammation [19], obesity [20], or sports science [21]. An area of great interest is nephrology since it has been shown that bioimpedance methods can help in the dialysis process to achieve the desired euvolemic state [12].…”

This work develops a thorough review of bioimpedance systems for healthcare applications. The basis and fundamentals of bioimpedance measurements are described covering issues ranging from the hardware diagrams to the configurations and designs of the electrodes and from the mathematical models that describe the frequency behavior of the bioimpedance to the sources of noise and artifacts. Bioimpedance applications such as body composition assessment, impedance cardiography (ICG), transthoracic impedance pneumography, electrical impedance tomography (EIT), and skin conductance are described and analyzed. A breakdown of recent advances and future challenges of bioimpedance is also performed, addressing topics such as transducers for biosensors and Lab-on-Chip technology, measurements in implantable systems, characterization of new parameters and substances, and novel bioimpedance applications.

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.
