background: the association of duration of breastfeeding (bf)  with  weight disorders remains controversial.  this study aimed to evaluate the association of bf with anthropometric measures and weight disorders in iranian children and adolescents. materials and methods: using multistage random cluster sampling method, a representative sample of 25,000 school students were selected from urban an...

Background: The aim of this study is to estimate the relationship between the new anthropometric parameters [waist circumference to height ratio (WHtR), body adiposity index (BAI) and visceral adiposity index (VAI)] and some inflammatory markers (hsCRP, fibrinogen and TNF-alpha). Methods: Randomly selected 182 healthy adult men included to this study. Height, body weight (BW), waist circumferen...

Introduction. Significant correlations between BMI and some body circumferences have been previously reported. In this study we investigated if the average of the sum of eight body circumferences can be a substitute for BMI. Patients and Methods. BMI and eight body circumferences (neck, waist, hip, arm, forearm, wrist, thigh, and ankle) were measured in 193 apparently healthy women aged 20-83, ...

The energy demands of pregnancy and lactation together with the accumulation of stored fat in human females during development suggest that a critical level of fat may be required for menarche; but multivariate analyses have supported the alternative view that skeletal growth is the main factor. However, significant differences between upper- and lower-body (gluteofemoral) fat suggest that fat ...

BACKGROUND Obesity increases cardiovascular risk through effects on blood pressure, lipoproteins, coagulation factors and inflammatory cytokines, but in women variation in fat distribution complicates these relationships. Central (male-type or visceral) obesity confers greater risk than the more generalised (female) type. This is recognised by the metabolic syndrome which employs waist circumfe...

Worldwide, lung cancer in never-smokers is ranked the seventh most common cause of cancer death; however, the etiology of lung cancer in never-smokers is unclear. We investigated associations for body mass index (BMI) at various ages, waist circumference, hip circumference, and physical activity with lung cancer in 158,415 never-smokers of the NIH-AARP Diet and Health Study. Multivariable hazar...

BACKGROUND Muscle mass reflects and influences health status. Its reliable estimation would be of value for epidemiology. OBJECTIVE The aim of the study was to derive and validate anthropometric prediction equations to quantify whole-body skeletal muscle mass (SM) in adults. DESIGN The derivation sample included 423 subjects (227 women) aged 18-81 y with a body mass index (BMI; in kg/m(2)) ...

CONTEXT Little is known of the relationships between muscle function and bone, based on the recently developed technique of jumping mechanography. OBJECTIVE Our objective was to determine associations between peak ground reaction force and peak power during a 1-legged hopping test and a single 2-legged jump, respectively, and cortical bone parameters. DESIGN AND SETTING This was a cross-sec...

To retrospectively determine the proportion of prostate cancer patients who are appropriate candidates for prostate localization with Calypso (Calypso Medical, Seattle, WA); to assess the accuracy of surface anatomy in predicting prostate depth; and to describe a simple clinical algorithm predicting patient's appropriateness for Calypso localization. Medical records and archived CT scans of all...

objectives: to compare bmi and inverted bmi in evaluating body measurement, resting blood pressure, dual energy x-ray absorptiometry (dexa) parameters of fat mass and metabolic risk factors in iranian children materials and methods: this is a cross-sectional study on 477 children aged 9-18 yearsin the south of iran. weight, height, resting blood pressure, waist and hip circumference and puberta...
