OBJECTIVE To determine whether adolescents with type 1 diabetes have left ventricular functional changes at rest and during acute exercise and whether these changes are affected by metabolic control and diabetes duration. RESEARCH DESIGN AND METHODS The study evaluated 53 adolescents with type 1 diabetes and 22 control adolescents. Baseline data included peak exercise capacity and body compos...

BACKGROUND Obesity is associated with mobility reduction due to mechanical factors and excessive body fat. The six-minute walk test (6MWT) has been used to assess functional capacity in severe obesity. OBJECTIVE To determine the association of BMI, total and segmental body composition with distance walked (6MWD) during the six-minute walk test (6MWT) according to gender and obesity grade. S...

BACKGROUND African Americans have a lower resting energy expenditure (REE) relative to fat-free mass (FFM) than do whites. Whether the composition of FFM at the organ-tissue level differs between African Americans and whites and, if so, whether that difference could account for differences by race in REE are unknown. OBJECTIVE The objectives were to quantify FFM in vivo in women and men at th...

Presently the conventional structure of personality, the Five-Factor Model (FFM), has faced criticism for inadequately capturing the full range of existing traits, particularly those reflecting antisocial behavior. The FFM has also not received sufficient application of genetically informed analyses to its extraction and validation. We explored these criticisms, and carried out four behavioral ...

Individuals with a personality disorder (PD) tend to experience more negative life events (NLEs) than positive life events (PLEs). In community samples, the Five Factor Model of personality (FFM) predicts both positive and negative life events. The present research examined whether FFM normal personality traits were associated with positive and negative life events among individuals with 1 of 4...

The factors in self-report inventories measuring the five-factor model (FFM) correlate with one another although they theoretically should not. Study 1 showed, across three different FFM-questionnaires, that almost all of the common variance between factors can be attributed to a single general factor related to social desirability. In Study 2, simple rephrasing of items from a FFM-questionnair...

BACKGROUND The relationship between maternal body compositions and birth weight was not definite. Fat Mass (FM) and Fat Free Mass (FFM) can accurately reflect the maternal body fat compositions and have been considered as better predictors of birth weight. Despite its potential role, no studies have been described the maternal compositions during pregnancy in East Asian women previously. We inv...

BACKGROUND Little is known about the distributions of percentage body fat (PBF), total body fat (TBF), and fat-free mass (FFM) in the adult population in the United States. OBJECTIVES We sought to estimate the means and percentile cutoffs of PBF, TBF, and FFM and to assess the differences by sex, age, race-ethnicity, and body mass index in US adults. DESIGN Data from the National Health and...

BACKGROUND Little is known about the relation between body composition and energy metabolism in paraplegia. OBJECTIVE We investigated the relation between body composition and energy metabolism in healthy paraplegics as compared with able-bodied control subjects. We hypothesized that paraplegics would have lower fat-free mass (FFM), body cell mass (BCM), resting metabolic rate (RMR), and ther...
