BACKGROUND: An accurate description of physical activity (PA) at school is required for appropriate health interventions. We examined PA patterns of children, and identified time periods that influenced them. METHODS: Forty students in 5 Japanese primary schools were asked to wear triaxial accelerometers for at least7 days. We obtained coefficients of variance (CV) at 15 min intervals, and conducted factor analysis of the school periods. A questionnaire was used to investigate where students spent time before school, and during recesses...

BACKGROUND: China is experiencing severe ambient air pollution. However, few studies anywhere have examined the health effects of PM1 (particulate matter with aerodynamic diameter <1 μm), which are a major part of PM2·5 (particulate matter with aerodynamic diameter <2·5 μm) and even potentially more harmful than PM2·5 . We aimed to estimate the effects of ambient daily PM1 and PM2·5 concentrations on emergency hospital visits in China. METHODS: In this epidemiological study, we collected daily counts of emergency hospital visits from the 28 largest hospitals in 26 Chinese cities from Sept 9, 2013, to Dec 31, 2014...

Television (TV) advertising of food and beverages high in fat, sugar and salt (HFSS) influences food preferences and consumption. Children from lower socioeconomic position (SEP) have higher exposure to TV advertising due to more time spent watching TV. This paper sought to estimate the cost-effectiveness of legislation to restrict HFSS TV advertising until 9:30 pm, and to examine how health benefits and healthcare cost-savings differ by SEP. Cost-effectiveness modelling was undertaken (i) at the population level, and (ii) by area-level SEP...

Juvenile Localized Scleroderma (JLS) is a rare disorder that may cause severe aesthetic sequelae and functional disability. To date, data on natural history and long-term outcome are discordant and difficult to compare due to the heterogeneity of clinical subtypes, treatments and methods to evaluate activity and outcome in previous studies. A retrospective and cross-sectional study including 133 patients followed between January 1991 and December 2016 was conducted at our Pediatric Rheumatology Centre. Disease course was drawn by retrospective analysis of patients' clinical features, treatment, disease course and outcome at the last evaluation...
