The Web’s global reach provides evolutionary behavioral scientists unique opportunities to investigate human universals steeped in a common and evolved human nature. In the current article, it is argued that many forms of online sexual communication are indicative of our evolved mating minds, including the manner by which female escorts are “advertised” online. It is demonstrated that online ad...

Central obesity increases the risk for cardiovascular disease, but little is known about its hemodynamic effects. The aims were to investigate the influence of obesity (as defined by body mass index) and abdominal fat accumulation (as defined by the waist/hip ratio) on hemodynamics at rest and during mental stress. Invasive hemodynamic studies were performed in 20 healthy, normotensive young me...

Objective: To evaluate the efficacy of anthropometric and body composition parameters in the prediction of body fat percentage and lipid profile in schoolchildren. Methods: Cross-sectional study with 209 schoolchildren aged between seven and nine years old. The following variables were evaluated: weight, height, body mass index, percentage of body fat, arm and waist circumferences, conicity ind...

The purpose of our investigation was to study the relationship between radiographic results of the femoral head and pain in people with severe cerebral palsy. We conducted a cross-sectional study on hip radiography results and pain in 160 patients with severe cerebral palsy. Eighteen percent of our patients had hip pain in hip-loading situations. Migration and deformity were closely related. Th...

This research examined human preference for water and a key aspect of water, its reflection. We compared responses to reflection in water versus reflection in glass and responses to reflection versus transparency. Sixty respondents rated the attractiveness of four scale-models varied on those dimensions. High inter-item reliability across the rating scales called for their combination into a co...

The effect of protein on bone is controversial, and calcium intake may modify protein's effect on bone. We evaluated associations of energy-adjusted tertiles of protein intake (ie, total, animal, plant, animal/plant ratio) with incident hip fracture and whether total calcium intake modified these associations in the Framingham Offspring Study. A total of 1752 men and 1972 women completed a base...

BACKGROUND Despite increasing evidence of a common link between bone and heart health, the relationship between bone mineral density (BMD) and heart failure (HF) risk remains insufficiently studied. METHODS AND RESULTS We investigated whether BMD measured by dual-energy x-ray absorptiometry was associated with incident HF in an older cohort. Cox models were stratified by sex and interactions ...

Objective: To compare average electromyogram (EMG) activity of the vastus medialis obliquus (VMO) and vastus lateralis (VL) during straight-leg raise (SLR) and knee extension (KE) with the hip in neutral and lateral rotation. Design: 1  4 factorial repeated-measures. Setting: Laboratory. Participants: 13 male college students. Intervention: SLR with hip flexed at 40°, in neutral position, and ...

There is increasing evidence that proximal femoral geometry has an important role in the aetiology of hip fractures. We performed a simple radiological study to investigate the relationship between proximal femoral geometry and intracapsular and extracapsular fractures of the proximal femur. Measurements of proximal femoral geometry were made on pelvic radiographs on the contralateral hip of 50...

OBJECTIVE To test the hypothesis that farmers are at high risk of hip osteoarthritis and to investigate possible causes for such a hazard. DESIGN Cross sectional survey. SETTING Five rural general practices. SUBJECTS 167 male farmers aged 60-76 and 83 controls from mainly sedentary jobs. All those without previous hip replacement underwent radiography of the hip. MAIN OUTCOME MEASURES H...
