OBJECTIVE It is unclear whether the demands of good metabolic control or the consequences of poor control have a greater influence on quality of life (QOL) for adolescents with diabetes. This study aimed to assess these relations in a large international cohort of adolescents with diabetes and their families. RESEARCH DESIGN AND METHODS The study involved(More)
Insulin regimens and metabolic control in children and adolescents with Type 1 diabetes mellitus were evaluated in a cross-sectional, non-population-based investigation, involving 22 paediatric departments, from 18 countries in Europe, Japan, and North America. Blood samples and information were collected from 2873 children from March to August 1995. HbA1c(More)
OBJECTIVE Twenty-one international pediatric diabetes centers from 17 countries investigated the effect of simple feedback about the grand mean HbA(1c) level of all centers and the average value of each center on changes in metabolic control, rate of severe hypoglycemia, and insulin therapy over a 3-year period. RESEARCH DESIGN AND METHODS Clinical data(More)
Longitudinal studies in Japan indicate that nocturnal sleep onset has become later and sleep duration has been progressively shortened. This study aimed to investigate the relationship between sleep patterns and sleep problems among children, and to determine the association between parents and their children's sleep habits. Questionnaires about sleep(More)
BACKGROUND It has been suggested that the daytime napping patterns of children differ according to racial and cultural backgrounds.

METHODS The mothers of 967 children between 0 and 5 years(More)
Several studies have reported that some people have the ability to awaken from sleep without using external means. This ability is called 'self-awakening'. The present study investigated the sleep/wake habits of university students with or without a habit of self-awakening. Of the 643 university students, 66 students (10.3%) habitually self-awakened in(More)
Sleep problems are known to be risk factors for subsequent emotional and behavioral difficulties in childhood and adolescence. To date, there has been no study investigating the relationships between sleep habits and behavioral problems in a large nonclinical sample of preschool age children. The aim of this study was to examine these relationships and(More)
Self-awakening (SA) is awakening by oneself at predetermined time without external means. Attempting to SA produces various kinds of preparatory changes over the course of a sleep period, including contributing to a decline in the waking threshold immediately before awakening. As a result, one can easily awake from sleep, and sleep inertia immediately after(More)
