When a tree, at a point where the circumference is Co, divides into two branches (cl and ct), what relationship exists between co and cl + c~? In order to answer this question, which has a definite bearing on problems of tree form, it is convenient to investigate first the relationship between the circumference at some point and the weight, w, of all the parts of the tree peripheral to this poi...

BACKGROUND Because of previously reported ethnic differences in determinants and markers of obesity and related metabolic disorders, we sought to investigate circulating levels of adiponectin and their correlates in a sub-Saharan African (sSA) population. SUBJECTS AND METHODS We studied 70 non-diabetic volunteers (33M/37F) living in Yaoundé, Cameroon, aged 24-69 yr, with BMI 20-42 kg/m2. In a...

OBJECTIVE Metformin produced weight loss and delayed or prevented diabetes in the Diabetes Prevention Program (DPP). We examined its long-term safety and tolerability along with weight loss, and change in waist circumference during the DPP and its long-term follow-up. RESEARCH DESIGN AND METHODS The randomized double-blind clinical trial of metformin or placebo followed by a 7-8-year open-lab...

Head circumference measurements from birth to 7 years, obtained from longitudinal data on children born between 1970 and 1977, are set against those from studies made in the United Kingdom earlier this century. A positive secular trend is shown. The children's heads were significantly larger than those born in the same locality 25 years earlier. Growth charts should be updated, as necessary, wi...

INTRODUCTION AND OBJECTIVE Obesity is associated with high rates of dyslipidemia and glucose intolerance. The objective of this study was to evaluate the correlation of anthropometric indices with the lipid and glucose profiles of outpatients. METHODS We performed a cross-sectional study assessing anthropometric and metabolic parameters in a sample of 550 individuals. RESULTS The prevalence...

BACKGROUND Using the intubation difficulty scale (IDS), we sought to confirm that obese patients are more difficult to intubate than lean patients. We assessed classical bedside tests and included neck circumference. METHODS We prospectively compared the incidence of difficult tracheal intubation in 70 obese [body mass index (BMI) > or = 30 kg/m(2)] and 61 lean patients (BMI < 30 kg/m(2)). Th...

CONTEXT Data supporting physical activity guidelines to prevent long-term weight gain are sparse, particularly during the period when the highest risk of weight gain occurs. OBJECTIVE To evaluate the relationship between habitual activity levels and changes in body mass index (BMI) and waist circumference over 20 years. DESIGN, SETTING, AND PARTICIPANTS The Coronary Artery Risk Development ...

birth weight is an important indicator of child survival. appropriate and timely care of a newborn specially if he or she is born with low birth weight is important but this is difficult in developing countries since most of the deliveries are conducted at home where adequate facilities to weight a new born does not exist. this study was conducted to find out a surrogate which could efficiently...

BACKGROUND The aim of this study was to identify corresponding body mass index (BMI) and waist circumference cut-offs for equivalent levels of insulin sensitivity in a Middle Eastern immigrant population compared with native Swedes. METHODS Citizens of Malmö, Sweden aged 30 to 75 years, who were born in Iraq or Sweden, were in 2010-2012 invited to participate in a health examination including...

Waist circumference is a good predictor of the risk of heart diseases, but data on the relationship between waist circumference and pulmonary diseases are sparse. The aim of this study was to investigate its influence on pulmonary function regarding exercise capacity in moderate and severe chronic obstructive pulmonary disease (COPD), according to Global Initiative for Lung Diseases (GOLD) stag...
