INTRODUCTION Placental vascular development, and ultimately placental weight, is essential to healthy fetal development. Here, we examined placental weight in a cohort of Tanzanian women in association with angiogenic proteins known to regulate placental vascular development and perinatal outcomes. METHODS A total of n = 6579 women with recorded placental weight were included in this study. T...

background obesity is one of the most common nutritional problems in adolescent. knowing eating behavior of adolescents improve our understanding about this pandemic and helps design an appropriate preventive and care plan. methods in a cross-sectional study, 372 students selected randomly from 8 guidance schools of shiraz, iran, during august-december 2009. body weight was measured to the near...

Adolescent patients with obesity are at significant risk of developing an eating disorder (ED), yet due to their higher weight status their symptoms often go unrecognized and untreated. Although not widely known, individuals with a weight history in the overweight (BMI-for-age ≥85th percentile but <95th percentile, as defined by Centers for Disease Control and Prevention growth charts) or obese...

OBJECTIVE To compare the growth of Brazilian children and adolescents with reference growth charts. METHODS School-based cross-sectional study involving 41,654 students (23,328 boys and 18,326 girls) aged 7 to 17 years. Physical growth variables (body weight, height) and body mass index (BMI) were measured. Height, 50th percentile, and BMI, 85th percentile, were compared with the World Health...

Background: In developed countries, overweight and obesity in children and adults is considered as basic problems. Several surveys show increasing trend of childhood obesity in developing countries, particularly in the Middle East and because of its risky role on people’s health, researchers aimed to assess the relations between birth weight and BMI in primary school children of Rasht/Iran. Mat...

conclusions in conclusion, the prevalence of sga was approximately one tenth of all pregnancies. sga incidence was associated with nulliparity and more frequently seen in lower age group. results of 312 pregnant women, 33 had sga fetuses. the average of body mass index (bmi) was lower in sga group than non-sga. pulsatility index has no stastical meaningful between sga and nonsga groups. in gest...

Introduction: Although there are several reports on the prevalence of underweight or obesity in low birth weight (LBW, <2.5 kg) children, there are few longitudinal studies from birth to early infancy. Methods: We enrolled 177 (93 boys) LBW and 2485 (1267 boys) normal birth weight (NBW, ≥2.5 and <4.0 kg) children. Height and weight data at birth and at 1.5, 3.5, and 5 years were obtained from m...

BACKGROUND This study assessed the association between amount of physical activity and body mass index (BMI) percentile among middle and high school children. Total daily physical activity needs to include both in and out of school physical activity. METHODS A secondary data analysis was performed on 1306 children drawn from the Panel Study of Income Dynamics Child Development Supplement (CDS...

BACKGROUND Severe obesity is an important and distinct weight status classification that is associated with disease risk and is increasing in prevalence among youth. The ability to graphically present population weight status data, ranging from underweight through severe obesity class 3, is novel and applicable to epidemiologic research, intervention studies, case reports, and clinical care. ...

BACKGROUND Newborns of certain immigrant mothers are smaller at birth than those of domestically born mothers. Contemporary, population-derived percentile curves for these newborns are lacking, as are estimates of their risk of being misclassified as too small or too large using conventional rather than tailored birth weight curves. METHODS We completed a population-based study of 766 688 sin...
