The validity of the Child Feeding Questionnaire (CFQ), one of the measures used to assess parental child feeding practices and attitudes, has been confirmed in American populations. We used confirmatory factor analysis to test the validity and factor structure of the translated version of the CFQ among parents of Japanese elementary school children. The(More)
BACKGROUND Although maternal smoking during pregnancy has been reported to have an effect on childhood overweight/obesity, the impact of maternal smoking on the trajectory of the body mass of their offspring is not very clear. Previously, we investigated this effect by using a fixed-effect model. However, this analysis was limited because it rounded and(More)
BACKGROUND Low birth weight (LBW) infants do not form a homogeneous group; LBW can be caused by prematurity or poor fetal growth manifesting as small for gestational age (SGA) infants or intrauterine growth retardation. We aimed to clarify the relationship of maternal smoking with both SGA and preterm LBW infants. METHODS The study population comprised(More)
BACKGROUND The effect of sleep on the risk of developing diabetes has not been explored in an Asian population. The objective of this study is to investigate the effect of self-reported sleep duration and sleep quality on the risk of developing diabetes in a prospective cohort in Japan. METHODS Data were analyzed from the cohort of participants in a(More)
OBJECTIVE We investigated the impact of active smoking and exposure to passive smoke on the risk of developing diabetes. RESEARCH DESIGN AND METHODS Data were analyzed from a cohort of participants in the High-Risk and Population Strategy for Occupational Health Promotion Study (HIPOP-OHP) conducted in Japan from 1999 to 2004. Active and passive smoking(More)
BACKGROUND We previously reported that a number of factors related to maternal lifestyle during early pregnancy, including smoking, are associated with childhood obesity at 5 years of age. In the present study, we investigated whether the association with maternal smoking persisted to the age of 9-10 years. METHODS The study population comprised children(More)
UNLABELLED Aims/Introduction:  To examine the cross-sectional relationship between sleep duration and impaired glucose tolerance (IGT), including diabetes mellitus (DM), we analyzed a large-scale healthy workers database in Japan. MATERIALS AND METHODS   We examined the baseline database of 4143 participants (3415 men and 728 women) aged 19-69 years.(More)
BACKGROUND The aims of this study were to 1) determine the distinct patterns of body mass index (BMI) trajectories in Japanese children, and 2) elucidate the maternal factors during pregnancy, which contribute to the determination of those patterns. METHODOLOGY/PRINCIPAL FINDINGS All of the children (1,644 individuals) born in Koshu City, Japan, between(More)
OBJECTIVE To examine the relation between sleep duration and metabolic syndrome (MetS). METHODS We examined the baseline data from 4356 healthy workers (3556 men and 800 women) aged 19-69 years. The physical activity of each participant was classified according to the International Physical Activity Questionnaire (IPAQ). We defined four components of MetS(More)
OBJECTIVE Metabolomics is a promising approach to the identification of biomarkers in plasma. Here, we performed a population-based, cross-sectional study to identify potential biomarkers of alcohol intake and alcohol-induced liver injury by metabolomic profiling using capillary electrophoresis-mass spectrometry (CE-MS). METHODS Fasting plasma samples(More)
