Increasing rates of obesity and heart disease are compromising quality of life for a growing number of people. There is much research linking adult disease with the growth and development both in utero and during the first year of life. The pig is an ideal model for studying the origins of developmental programming. The objective of this paper was to construct percentile growth curves for the p...

OBJECTIVES In 2000, the Centers for Disease Control and Prevention (CDC) released a new set of childhood growth charts for the United States. These charts included a set of smoothed percentiles along with LMS (lambda-mu-sigma) parameters to allow the calculation of other percentiles or standard deviation scores. These parameters resemble the LMS parameters derived using Cole's LMS method. Simil...

BACKGROUND Left ventricular (LV) hypertrophy (LVH) in children is widely defined as a left ventricular mass index (LVMI, g/m(2.7)) >95th percentile. However, LVMI increases with decreasing height in young children; thus, the 95th percentile LVMI will depend on the height distribution of the reference population. The objective of this study was to compare the performance of a novel method of exp...

PURPOSE To construct new Korean reference curves for birth weight by sex and gestational age using contemporary Korean birth weight data and to compare them with the Lubchenco and the 2010 United States (US) intrauterine growth curves. METHODS Data of 2,336,727 newborns by the Korean Statistical Information Service (2008-2012) were used. Smoothed percentile curves were created by the Lambda M...

Localized birthweight references for gestational ages serve as an essential tool in accurate evaluation of atypical birth outcomes. Such references for twin births are currently not available in China. The aim of this study was to construct up-to-data sex specific birth weight references by gestational ages for twin births in China. We conducted a population-based analysis on the data of 22,507...

Methods We prospectively enrolled healthy 115 children and adolescents, mean age 12.4±4.1 years, range 4.4-20.3, with no acquired or congenital heart disease, no chronic illness or any competitive sports activities. Transversal routine 2D steady-state free-precession acquisition was used to cover the whole heart. We determined maximal and minimal volumes of both atria and calculated cyclic volu...

The CDC growth charts contain 10 smoothed percentiles (between the 3 and 97) of BMI for 24 to 240 month-old children and adolescents [3]. These smoothed estimates were subsequently used to derive lambda (L, the power transformation to achieve normality), mu (M, mean or median) and sigma (S, coefficient of variation) parameters for Cole's LMS method [4,5]. Estimates of these 3 parameters allow t...

Overweight children and childhood obesity are a public health problem in Mexico. Obesity is traditionally assessed using body mass index (BMI), but an excess of adiposity does not necessarily reflect a high BMI. Thus, body composition indexes are a better alternative. Our objective was to generate body composition percentile curves in children from Mexico City. A total of 2026 boys and 1488 gir...
