BackgroundThe World Health Organization's (WHO's) Health Promoting Schools (HPS) framework is an holistic, settings-based approach to promoting health and educational attainment in school. The effectiveness of this approach has not been previously rigorously reviewed. ObjectivesTo assess the effectiveness of the Health Promoting Schools (HPS) framework in improving the health and well-being of students and their academic achievement.

BackgroundHealthy children achieve better educational outcomes which, in turn, are associated with improved health later in life. The World Health Organization’s Health Promoting Schools (HPS) framework is a holistic approach to promoting health and educational attainment in school. The effectiveness of this approach has not yet been rigorously reviewed.MethodsWe searched 20 health, education and social science databases, and trials registries and relevant websites in 2011 and 2013.We included cluster randomised controlled trials. Participants were children and young people aged four to 18 years attending schools/colleges. HPS interventions had to include the following three elements: input into the curriculum; changes to the school’s ethos or environment; and engagement with families and/or local communities.Two reviewers identified relevant trials, extracted data and assessed risk of bias. We grouped studies according to the health topic(s) targeted. Where data permitted, we performed random-effects meta-analyses.ResultsWe identified 67 eligible trials tackling a range of health issues. Few studies included any academic/attendance outcomes. We found positive average intervention effects for: body mass index (BMI), physical activity, physical fitness, fruit and vegetable intake, tobacco use, and being bullied. Intervention effects were generally small. On average across studies, we found little evidence of effectiveness for zBMI (BMI, standardized for age and gender), and no evidence for fat intake, alcohol use, drug use, mental health, violence and bullying others. It was not possible to meta-analyse data on other health outcomes due to lack of data. Methodological limitations were identified including reliance on self-reported data, lack of long-term follow-up, and high attrition rates.ConclusionThis Cochrane review has found the WHO HPS framework is effective at improving some aspects of student health. The effects are small but potentially important at a population level.

ObjectiveTo describe levels of physical activity, sedentary time and adherence to Chief Medical Officers (CMO) physical activity guidelines among primary school-aged children across the UK using objective accelerometer-based measurements.DesignNationally representative prospective cohort study.SettingChildren born across the UK, between 2000 and 2002.Participants6497 7-year-old to 8-year-old singleton children for whom reliable accelerometer data were available for at least 10 h a day for at least 2 days.Main outcome measuresPhysical activity in counts per minute (cpm); time spent in sedentary and moderate-to-vigorous intensity physical activity (MVPA); proportion of children meeting CMO guidelines (≥60 min/day MVPA); average daily steps.Explanatory measuresGender, ethnicity, maternal current/most recent occupation, lone parenthood status, number of children in the household and country/region of residence.ResultsThe median daily physical activity level was 595 cpm (IQR 507, 697). Children spent a median of 60 min (IQR 47–76) in MVPA/day and were sedentary for a median of 6.4 h/day (IQR 6–7). Only 51% met CMO guidelines, with girls (38%) less active than boys (63%). Children took an average of 10 229 (95% CI (8777 to 11 775)) steps each day. Children of Indian ethnicity were significantly less active overall than all other ethnic groups. Children of Bangladeshi origin and those living in Northern Ireland were least likely to meet CMO guidelines.ConclusionsOnly half of 7-year-old children in the UK achieve recommended levels of physical activity, with significant gender, ethnic and geographic variations. Longitudinal studies are needed to better understand the relevance of these (in)activity patterns for long-term health and well-being. In the meantime population-wide efforts to boost physical activity among young people are needed which are likely to require a broad range of policy interventions.

A prospective study was conducted to determine risk factors for fungal colonization, drug susceptibility, and association with invasive fungal infections (IFIs) in a neonatal unit. On admission and weekly thereafter, surveillance fungal cultures were taken from mouth, rectum, and trachea of neonates with expected stays of > 1 week. Fungal colonization was detected in 72 (12.1%) of 593 neonates during 12 months. CANDIDA ALBICANS was isolated from 42% of colonized neonates. Although early colonization (age 1.3 +/- 0.2 days) was found in 2.5% of the neonates, late colonization (age 17.6 +/- 1.4 days) was noted in 14.2% of neonates hospitalized for > 5 days. Neonates born vaginally were at higher risk for early colonization than those delivered after cesarean section ( P = 0.01). By multivariate logistic regression, very low birthweight was the only independent risk factor for late colonization. Ten IFIs (nine candidemias) were diagnosed, yielding a rate of 1.1%. These episodes occurred in 6.9% of colonized neonates, compared with 0.76% of noncolonized neonates ( P = 0.002). C. ALBICANS was susceptible to azoles, but some non- ALBICANS CANDIDA spp. exhibited decreased susceptibility to these drugs.

Developing a better understanding of the school- and student-level characteristics associated with overweight among youth is critical for informing intervention programs and policies.

Parent-offspring associations in BMI were not explained by offspring lifestyles, but varied over successive generations and by social class, suggesting that intergenerational transmission of adiposity at a population level is modifiable rather than immutable.
