“…Anthropometric and body composition variables showed correlation with the PEF, corroborating with the results of several other studies [9,16,19,30,31]. The results of our research elucidated that maternal age and height were positively related to the PEF in primigravidae.…”

“…In view of the factors that can influence the PEF such as sex, age, height, race and BMI [9,[16][17][18]. It is noted the importance of monitoring changes in pregnancy weight, since the progressive changes in the form and abdomen configuration, diaphragm and ribcage, besides increasing the size of the uterus and fetal growth could compromise pulmonary function during gestation [9,15,19].…”

Objectives: To describe and compare the mean values of the body composition and the peak expiratory flow (PEF) in primigravidae and multigravidae and, to determine its correlation with obstetric, anthropometric and body composition variables. Method:It was performed a cross-sectional study of 120 healthy pregnant women at low risk, including 77 primigravidae and 43 multigravidae. The PEF was measured by spirometry and the body composition by multisegmental electrical impedance. The unpaired t test was used to compare the groups and the Pearson correlation test was used to determine the association between PEF and independent variables. A multiple linear regression was used to estimate the relationship between the dependent variable, the PEF and the independent variables. Results: The body composition variables in multigravidae womenshowed higher values compared to the primigravidae, being statistically significant, except for fat mass. In primigravidae, the PEF was correlated significantly with maternal age and height. In multigravidae, the PEF was correlated with maternal age, height, pre-pregnancy and current weight, total body water, extracellular water, fat mass, lean mass and fat-free mass. A Multiple linear regression analysis showed that, in primigravidae, height and maternal age were associated with

“…The change in the measured V TG was signifi- This association between WC changes and measured V TG changes might be explained by a variety of mechanisms. Abdominal fat deposition may directly impede the descent of the diaphragm into the abdominal cavity, whereas fat deposition in the chest wall may diminish rib cage movement and thoracic compliance, both of which lead to restrictive respiration impairment (Maiolo et al, 2003). Other mechanisms have been suggested, including the possibility that abdominal fat deposition leads to a redistribution of blood to the thoracic compartment that reduces vital capacity (Harik-Khan et al, 2001).…”

Changes in thoracic gas volume with air-displacement plethysmography after a weight loss program in overweight and obese women

Objective: This study was designed to compare measured and predicted thoracic gas volume (V TG ) after weight loss and to analyze the effect of body composition confounders such as waist circumference (WC) on measured V TG changes. Design: Prospective intervention study. Setting: Outpatient University Laboratory, Lisbon, Portugal. Subjects: Eighty-five overweight and obese women (body mass index ¼ 30.073.5 kg/m 2 ; age ¼ 39.075.7 years) participating in a 16-month university-based weight control program designed to increase physical activity and improve diet. Methods: Body weight (Wb), body volume (Vb), body density (Db), fat mass (FM), percent fat mass (%FM) and fat-free mass (FFM) were assessed by air-displacement plethysmography (ADP) at baseline and at post-intervention (16 months). The ADP assessment included a protocol to measure V TG and a software-based predicted V TG . Dual-energy X-ray absorptiometry (DXA) (Hologic QDR 1500) was also used to estimate FM, %FM and FFM. Maximal oxygen uptake (VO 2 max) was assessed with a modified Balke cardiopulmonary exercise testing protocol with a breath-by-breath gas analysis. Results: Significant differences between the baseline and post-weight loss intervention were observed for body weight and composition (Vb, Db, %FM, FM and FFM), and measures of V TG (measured: D ¼ 0.2 l, Po0.001; predicted: D ¼ 0.01 l, Po0.010) variables. Measured V TG change was negatively associated with the change in the WC (P ¼ 0.008), controlling for VO 2 max and age (P ¼ 0.007, P ¼ 0.511 and P ¼ 0.331). Linear regression analysis results indicated that %FM and FM using the measured and predicted V TG explained 72 and 76%, and 86 and 90% respectively, of the variance in %FM and FM changes using dual-energy x-ray absorptiometry. Conclusions: After weight loss, measured V TG increased significantly, which was partially attributed to changes is an indicator of body fat distribution such as WC. Consequently, measured and predicted V TG should not be used interchangeably when tracking changes in body composition. The mechanisms relating the reduction of an upper body fat distribution with an increase measured V TG are worthy of future investigation.

“…In the studies conducted in obese people, it has been suggested that the decrease in the chest wall compliance may be caused by adipose tissue around the abdomen (12). The effects of obesity was determined as reduction in functional residual capacity and expiratory reserve volume and increase in residual volume (13).…”

Objective: Body mass index (BMI) is used as a basic parameter in assessing obesity. However, BMI is not sensitive in the assessment of body fat percentage (BFP) and body fat distribution (BFD). The aim of this study is to determine the effect of BFP and BFD on the pulmonary functions and compare this effect with BMI. Methods:This study was conducted with a total of 170 volunteers. BMI, waist-to-hip ratio (WHR), and BFPs of healthy normal weight, overweight, and obese individuals were measured and their pulmonary function tests were statistically compared with each other. Results:There was no significant relationship between BMI increase and pulmonary function test results of the individuals. There were significant correlations between BFP increase and forced expiratory volume (FEV 1 %) and forced expiratory flow between 25% and 75% of FVC (FEF25-75%). In the male patients, FEV 1 % value was negatively correlated with waist circumference. In female patients, WHR was positively correlated with FEV 1 /forced vital capacity (FVC), FEV 1 /FVC%, whereas it was negatively correlated with FEV 1 % values. Conclusion:Because the widely used BMI is incapable of distinguishing BFP and BFD, it can be insufficient for evaluating the lung functions.Therefore, determining the body composition is important in the evaluation of obese individuals.
