Mathematica Policy Research posted a new research brief that summarises findings from a study of Healthy Harlem, an after-school programme aimed at promoting healthy lifestyles. The study, by James Mabli, Martha Bleeker and Mary Kay Fox, showed that participation in the Healthy Harlem programme led to increased physical activity and improved weight status for overweight and obese pupils.
Key components of Healthy Harlem include physical activity, healthy snacks, nutrition education lessons and parent workshops. To assess Healthy Harlem’s effectiveness, the authors monitored pupils at 21 after-school sites during an initial baseline year and then measured programme impacts after two and three years of participation. They collected data through a pupil survey, a fitness test and direct measurements of height and weight. Key findings were as follows:
- A 5.5 percent decrease in mean BMI z-scores after two years of participation and a 9.0 percent decrease after three years of participation. According to the report, a BMI z-score reflects the number of standard deviations a pupil’s BMI is from the mean BMI for a reference population.
- A decrease of 12.2 percentage points in the percentage of pupils who were overweight or obese after two years, and a decrease of 18.4 percentage points after three years.
- An increase in the percentage of pupils considered to be within the Harlem Fitness Zone, a measure of fitness based on a pupil’s ability to complete a minimum number of laps, defined for age-and-gender subgroups.

Many studies have been conducted to examine the impact for pupils of later school start times, some of which can be found in previous issues of Best Evidence in Brief. This Campbell systematic review summarises the findings from 17 studies to examine the evidence on the impact of later school start times on pupils’ mental health and academic performance.
The studies included in the review were randomised controlled trials, controlled before-and-after studies and interrupted time series studies with data for pupils aged 13 to 19 and that compared different school start times. The studies reported on 11 interventions in six countries, with a total of almost 300,000 pupils.
The main results of the review suggest that later school starts may be associated with positive academic benefits and psychosocial outcomes. Later school start times also appear to be associated with an increase in the amount of sleep children get. Effect sizes ranged from +0.38 to +2.39, equivalent to an extra 30 minutes to 2 hours of sleep each night. However, the researchers point out that, overall, the quality of the body of evidence is very low, and so the effects of later school start times cannot be determined with any confidence.

In a new report from the Education Policy Institute, Emily Firth has examined the evidence of the impact of using social media on young people’s mental health and emotional well-being.
One of the key findings from the report is evidence of a beneficial impact. This is because young people can connect with others to improve their social skills online, develop their character and resilience and collaborate on school projects. In the recent PISA well-being survey of 15-year-olds, 90.5% of boys and 92.3% of girls in the UK agreed or strongly agreed with the statement “It is very useful to have social networks on the internet”. Also, importantly, those with mental health problems are able to use the internet to seek support, either through social media networks or through the online provision of advice and counseling support. For example, 78% of young people contacting the organisation Childline now do so online.
However, the report also highlights several negative effects on the well-being of young people linked with social media, including cyber-bullying, concerns about excessive use and sharing of private information and harmful content. It also finds that attempts to restrict children’s internet access are likely to be counterproductive as they hinder the development of vital skills needed to counter such risks. Rather than seeking to protect young people from all online risks, the report calls on policy makers to promote proactive measures that build resilience in children, in order to help them lead safe digital lives.

Students’ well-being: PISA 2015 results analyses pupils’ motivation to perform well in school, their relationships with peers and teachers, their home life and how they spend their time outside of school. The findings are based on a survey of 540,000 pupils in 72 participating Organisation for Economic Cooperation and Development (OECD) countries and economies.
The study found that pupils in the UK are among the least happy – ranking 38th out of the 48 OECD countries – with the US ranking slightly higher at 29th. On average, 15-year-old pupils in the US reported a level of 7.4 on a life satisfaction scale ranging from 0 to 10 (the OECD average was 7.3).
As in the majority of countries, boys in the UK and the US reported higher life satisfaction than girls (0.7 points higher for UK; 0.6 points higher for US; OECD average = 0.6).
Pupils in both the UK and the US reported higher levels of schoolwork-related anxiety than the OECD average. The study found 72% of UK pupils and 68% of US pupils felt anxious about tests, even when they were well-prepared for them, compared to the OECD average of 55%. And 61% of pupils in the US and 67% in the UK worry about getting poor grades at school.
Bullying is also an issue, particularly for the UK, with 25% of UK pupils and 19% of US pupils reporting that they are victims of one act of bullying at least a few times a month, compared to the OECD average of 19%.

A new report from the Public Policy Institute for Wales synthesises research and policy evaluations related to school-based strategies to promote emotional health, well-being, and resilience among primary school students aged 4 to 11 years.
The report argues that school-based work in this area can be very effective, and school systems need to be strongly connected with each other in order to translate the research evidence into sustained impact. While work on emotional health and well-being is relevant to all students, some children are likely to have additional needs. These children often come from high-risk groups that can be identified, for example, those who have socio-economically disadvantaged backgrounds.
The report’s overarching recommendation is to develop a carefully planned and well-supported approach to social and emotional learning (SEL) that is integrated with core pedagogical principles and situated within a connected school. It also calls for an independent evaluation of a Welsh initiative on SEL that is designed to support emotional health, well-being, and resilience. Importantly, the focus should not be on developing an entirely new SEL curriculum or new teaching resources, since many evidence-based programs with high-quality resources already exist. Rather, the emphasis should be on identifying specific strategies for integrating SEL work, engaging families, and broader schools systems and core pedagogical principles.

Child Trends has released a new research brief on mental wellness in early childhood. Using research from various sources such as university publications, journal articles, and government websites, they identify five “things to know” to help parents and caregivers lay a solid foundation for healthy childhood development.
- Infants experience and perceive a range of emotions. Caregivers may underestimate the degree to which infants’ social-emotional development is affected by early experiences. Although infants as young as six months can “begin to sense and be affected by their parents’ moods,” fewer than 35% of caregivers believe that infants are capable of experiencing emotions in this way.
- Early positive interactions promote emotional wellness throughout the lifespan. Interactions between caregivers and infants are critically important, as “neural connections are formed through the interaction of genes and a baby’s environment and experiences,” especially through communication with caregivers.
- Having appropriate expectations of young children’s development is important. Emotional development is a critical component of brain development that is not always emphasised as much as cognitive, physical, or verbal development. Each person’s development is unique, but caregivers should understand general social-emotional milestones – such as copying caregivers’ actions – in order to keep expectations appropriate and monitor potential red flags.
- Parents and caregivers should be mindful of their own emotional well-being, seeking support if they need it. Caregivers who effectively treat their mental illness may lower the effects of the illness on their children.
- Young children are resilient and, if properly supported, can overcome potentially traumatic events. Young children may be able to overcome the effects of adverse events through consistent, predictable, supportive interactions.
