Childhood asthma, a growing health concern, has been associated with low birth weight and elevated body mass index. This study tested the hypothesis that overweight and obese adolescents with a history of low birth weight are at even greater risk of developing asthma. A cohort of 75,871 junior high school students was screened for asthma during 1995-1996 in Taiwan. Birth weight and estimated ge...

Periodontitis is one of the most prevalent oral diseases. In this study, we probed the nationwide registered database to assess the time trends of prevalence of periodontitis in Taiwan.A retrospective study was conducted to analyze the registered database compiled by the National Health Insurance provided by the Department of Health, Taiwan, from 1997 to December 2013.We found that the prevalen...

Transparent boundary conditions (TBCs) are an important tool for the truncation of the computational domain in order to compute solutions on an unbounded domain. In this work we want to show how the standard assumption of ‘compactly supported data’ could be relaxed and derive TBCs for a generalized Schrödinger equation directly for the numerical scheme on the discrete level. With this inhomogen...

Residual stress arisen in fabrication process of Double-Ceramic-Layer Thermal Barrier Coating System (DCL-TBCs) has a significant effect on its quality and reliability. In this work, based on the practical fabrication process of DCL-TBCs and the force and moment equilibrium, a theoretical model was proposed at first to predict residual stress generation in its fabrication process, in which the ...

OBJECTIVE To examine the relation between birth weight and measured intelligence at age 7 years in children within the normal range of birth weight and in siblings. DESIGN Cohort study of siblings of the same sex. SETTING 12 cities in the United States. SUBJECTS 3484 children of 1683 mothers in a birth cohort study during the years 1959 through 1966. The sample was restricted to children ...

BACKGROUND We investigate patterns of neurodevelopmental trajectories in infants, using a representative population, and identify risk factors that predict delayed growth. METHODS Participating infants (n = 952; 82.8% of the total sample) were assessed by Mullen Scales of Early Learning at seven time points, from 1 month to 24 months of age. Mothers were recruited in early pregnancy and data ...

OBJECTIVE This study prospectively assessed the association between body mass index (BMI) and cognitive ability of young children, while accounting for confounding factors. METHODS The study included 236 children born between 1990 and 1994 participating in a Dutch birth cohort study. Anthropometric data of the children at birth, 4, and 7 years of age were collected from growth records or meas...

BACKGROUND Maternal depressive symptoms are negatively associated with early child growth in developing countries; however, few studies have examined this relation in developed countries or used a longitudinal design with data past the second year of the child's life. We investigated if and when early maternal depressive symptoms affect average growth in young children up to age 6 in a national...

American adults had sex about nine fewer times per year in the early 2010s compared to the late 1990s in data from the nationally representative General Social Survey, N = 26,620, 1989-2014. This was partially due to the higher percentage of unpartnered individuals, who have sex less frequently on average. Sexual frequency declined among the partnered (married or living together) but stayed ste...
