VE/VCO2 slope in lean and overweight women and its relationship to lean leg mass.

ABSTRACT: Ventilation/carbon dioxide production (VE/VCO2slope) is used clinically to determine cardiorespiratory fitness and morbidity in heart failure (HF). Previously, we demonstrated that lower lean leg mass is associated with high VE/VCO2slope during exercise in HF. In healthy individuals, we evaluated 1) whether VE/VCO2slope differed between lean and overweight women and 2) the relationship between lean leg mass and VE/VCO2slope in overweight sedentary (OWS), overweight trained (OWTR) and lean, trained (LTR) women. Methods:Gas exchange and ventilation were collected during a treadmill peak oxygen uptake test (VO2peak) in 40 women [26 OWS (29?±?7?yrs., mean?±?SD), 7 OWTR (33?±?5?yrs) and 7 LTR (26?±?6?yrs)]. Body composition was measured by dual X-ray absorptiometry. Results:VO2peak was highest in LTR (46.6?±?8?ml/kg/min) compared with OWTR (38.1?±?4.9?ml/kg/min) and OWS women (25.3?±?4.8?ml/kg/min, p??0.05). Higher lean leg mass was associated with lower VE/VCO2slope in overweight women (OWS?+?OWTR: r?=?-0.55, p?

Project description:Weight gain in pregnancy is an essential physiologic adaptation that supports growth and development of a fetus and is distributed among lean mass that includes total body water and fat mass gains. Although gestational weight gain provides a source of energy for the mother and fetus, excess gestational weight gain may underlie reported associations between parity and future metabolic disorders and is linked to postpartum weight retention and insulin resistance. Although weight gain often is proposed as a modifiable variable to mitigate adverse maternal and offspring health outcomes, our knowledge of specific maternal body composition changes with weight gain and the potential metabolic consequences is limited. Furthermore, although gestational weight gain alters maternal body composition, the impact of excess weight gain on fat and lean mass is not well-studied. Understanding the accrual of fat and lean body mass may improve our understanding of the role of excessive gestational weight gain and metabolic dysfunction.The purpose of our study was to quantify the relationship between gestational weight gain and maternal fat and lean body mass accrual and to compare fat and lean body mass accrual according to the 2009 Institute of Medicine Guidelines for Gestational Weight Gain in Pregnancy adherence. We hypothesized that exceeding current weight gain guidelines would be associated with greater fat, compared with lean body, mass accrual.This is a secondary analysis of a randomized controlled trial of 49 overweight/obese women; all 49 are included in this secondary analysis. Maternal weight and body composition were collected in early (13 0/6 to 16 6/7 weeks gestation) and late (34 0/7 to 36 6/7 weeks gestation) pregnancy with the use of air densitometry. Correlations were drawn between gestational weight gain and change in fat and lean body mass. We compared change in fat and lean body mass by adherence to the 2009 Institute of Medicine Guidelines for Gestational Weight Gain in Pregnancy. Nonparametric tests and chi-square analyses were performed; a probability value of <.05 was significant.Early pregnancy body mass index was 30.3 kg/m(2) (interquartile range [IQR], 28.5-35.2 kg/m(2)); women gained 9.0 kg (IQR, 5.3-13.2 kg). Overweight and obese women were equally likely to gain excess weight (48% vs 35%; P = .6). Weight gain correlated strongly with fat mass change (r = 0.87; P < .001); women with excess vs adequate vs inadequate weight gain had greater fat mass change overall (5.2 [IQR, 4.2-8.1] vs 0.2 [IQR, -0.4-2.2] vs -2.7 [IQR, -5.2- -0.7] kg, respectively; P < .001) and in all pairwise comparisons. Weight gain also correlated with lean body mass change (r = 0.52; P = .001), but women with excess vs adequate weight gain had similar lean body mass change (8.4 [IQR, 7.2-10.1] vs 7.8 [IQR, 6.0-8.7] kg; P = .1).Excess gestational weight gain is associated primarily with maternal fat, but not with lean body mass accrual. Our results may help explain the reason that excess gestational weight gain or fat mass accrual is associated with long-term obesity, metabolic dysfunction, and cardiovascular disease risk.

Project description:BACKGROUND:Prior research suggests that undernutrition and enteric infections predispose children to stunted growth. Undernutrition and infections have been associated with limited access to healthy diets, lack of sanitation, and access barriers to healthcare - all associated with human rights. Stunting has also been documented to be a major determinant of subsequent obesity and non-communicable diseases. Short leg length relative to stature during adulthood seems to be a good proxy indicator tracking such barriers, and has been reported to be associated with adverse health effects during adulthood. Our objective was to examine the association between relative leg length (as measured by the leg length index, LLI) and measures of adiposity - based on body mass index (BMI) and waist circumference (WC) - in a population of recent Mexican immigrant women to the New York City Area. METHODS:The analysis was based on a cross-sectional survey of 200 Mexican immigrant women aged 18 to 70?years, whose data were collected between April and November 2008; although for purposes of the current study we restricted the sample to those aged 18 to 59?years. The dependent variables were BMI and WC, both transformed into categorical variables. The main independent variable was LLI, and other correlates were controlled for (i.e. age, education, having had children, characteristics of the community of origin, acculturation, chronic conditions, sedentary behaviors, access to fresh fruits and vegetables). Two probit models were estimated: the first one analyzed the effect of LLI on BMI categories and the second one estimated the effect of LLI on WC. RESULTS:The probit assessing the effect of LLI on overweight/obesity suggested that having a short LLI increased the probability of overweight/obesity by 21 percentage points. Results from the probit model estimating the effect of LLI on WC indicated that having a short LLI increased the probability of having abdominal adiposity by 39 percentage points. Both results were statistically significant at p?<?0.05. CONCLUSION:The study found an association between having shorter legs relative to one's height and increased risk of overweight/obesity and abdominal adiposity. Findings support the epidemiological evidence regarding the association between short leg length, early life socioeconomic conditions (i.e. limited access to basic rights), and increased risk of adverse health effects later in life.

Project description:BACKGROUND:Maintenance of lean muscle mass and related strength is associated with lower risk for numerous chronic diseases of aging in women. OBJECTIVE:Our aim was to evaluate whether the association between dietary protein and lean mass differs by physical activity level, amino acid composition, and body mass index categories. DESIGN:We performed a cross-sectional analysis of a prospective cohort. PARTICIPANTS/SETTING:Participants were postmenopausal women from the Women's Health Initiative with body composition measurements by dual-energy x-ray absorptiometry (n=8,298). MAIN OUTCOME MEASURES:Our study measured percent lean mass, percent fat mass, and lean body mass index. STATISTICAL ANALYSES PERFORMED:Linear regression models adjusted for scanner serial number, age, calibrated energy intake, race/ethnicity, neighborhood socioeconomic status, and recreational physical activity were used to determine the relationship between protein intake and body composition measures. Likelihood ratio tests and stratified analysis were used to investigate physical activity and body mass index as potential effect modifiers. RESULTS:Biomarker-calibrated protein intake was positively associated with percent lean mass; women in the highest protein quintile had 6.3 percentage points higher lean mass than the lowest quintile (P<0.001). This difference rose to 8.5 percentage points for physically active women in the highest protein quintile (Pinteraction=0.023). Percent fat mass and lean body mass index were both inversely related to protein intake (both P<0.001). Physical activity further reduced percent fat mass (Pinteraction=0.022) and lean body mass index (Pinteraction=0.011). Leucine intake was associated with lean mass, as were branched chain amino acids combined (both P<0.001), but not independent of total protein. All associations were observed for normal-weight, overweight, and obese women. CONCLUSIONS:Protein consumption up to 2.02 g/kg body weight daily is positively associated with lean mass in postmenopausal women. Importantly, those that also engage in physical activity have the highest lean mass across body mass index categories.
