BACKGROUND Obesity is associated with increased risk for stroke. The breath-holding index (BHI) is a measure of vasomotor reactivity of the brain which can be measured with the transcranial Doppler (TCD). We aim to evaluate obesity as an independent factor for altered cerebrovascular reactivity. METHODS Cerebrovascular hemodynamics (mean flow velocities MFV, pulsatility index, PI, resistance ...

Locally acting fat depots may contribute to obesity complications, in particular vascular disease, through direct paracrine effects (1,2). The carotid arteries are encased in fat, and total upperbody subcutaneous fat is estimated by neck circumference (NC). NC has been independently correlated with cardiometabolic risk factors above and beyond that of other adiposity measures (3,4). Carotid wal...

BACKGROUND Obesity levels have been dramatically increased in the United Arab Emirates over the last few years. High levels of body Mass Index, waist circumference, and percent of total body fat as a measure of obesity have found to be related to cardiovascular risk factors and other diseases. Neck circumference is a new tool that has been linked to obesity. However, no studies in UAE have been...

Chronic kidney disease (CKD) is characterized by increased risks of morbidity and mortality. Upper-body subcutaneous fat, which is commonly estimated from the neck circumference (NC), was revealed to be the main reservoir of circulating nonesterified fatty acids in overweight patients. Despite a close association between NC and metabolic complications, the relationship of NC with renal function...

BACKGROUND The predictive potentials of neck circumference (NC) for cardio-metabolic risks remain uncertain. The aim of this study was to investigate whether NC independently contributes to the prediction of cardio-metabolic risks beyond body mass index (BMI), waist circumference (WC) and waist to hip ratio (WHpR) in a large Chinese population. METHODS A total of 4201 participants (2508 men a...

OBJECTIVE To compare the growth and development of twins with normal control singletons and also with matched 'high risk' singletons, at one and four years of age. DESIGN A four year prospective follow up study. SETTING High risk clinic (HRC) of a referral hospital. SUBJECTS Twin pairs enrolled in the HRC; normal full term singleton controls; and high risk "matched" singletons enrolled in...

Familial correlations in birth weight and gestational age have been explained by fetal and maternal genetic factors, mainly in studies on offspring of twins. The aim of the present intergenerational study was to estimate and compare fetal and maternal genetic effects and shared sibling environmental effects on birth weight and gestational age and also on crown-heel length and head circumference...

The head circumference of a long-stay population with schizophrenia was compared with that of a population with dementia, matched for sex and year of birth. Schizophrenics had a smaller head circumference, even after correction for height and weight. This confirms earlier but inconclusive and controversial reports, and might be taken as supporting a neurodevelopmental hypothesis of the aetiolog...

Reference range for head circumference on the Tanner charts do not go beyond age 16. In this study the head circumference and heights of 354 adults in two British centres were measured. The centile charts constructed from these measurements show that adult head circumference is related to height. The mean head circumference of a male of average height is above the 97th centile for a 16 year old...
