Adolescence is a window of opportunity for improving health literacy

A study by the University of Southampton has shown its LifeLab program, aimed at improving adolescent health through hands-on learning, significantly increases young people’s understanding of what it means to lead a healthy lifestyle.

Led by a team from both the Faculty of Medicine and Education School at the University of Southampton, the LifeLab program aims to encourage engagement with the science behind public health messages, to support development of health literacy alongside decision-making skills and promotion of adolescents’ sense of control over their lives and futures. Based at University Hospital Southampton (UHS) NHS Foundation Trust, LifeLab is a state-of-the-art teaching laboratory dedicated to improving adolescent health through science engagement.

Latest research, published in the journal PLOS ONE1 and funded by the British Heart Foundation, has found that participation in LifeLab was associated with an increase in students’ health literacy 12 months later. There was also evidence that participants subsequently judged their own lifestyles more critically than students who had not taken part in the program.

Health literacy can be described as having the knowledge, skills, understanding and confidence to use health and care information and services and to apply these to lifestyle choices. Increasing evidence suggests that adolescence is a critical developmental stage during which lifelong health literacy can be established, offering a potential window of opportunity during which improvements in health literacy could benefit long-term health, and enable preparation for parenthood—passing on good health prospects to future children.

The randomized controlled trial was conducted in 38 secondary schools in England, drawing on principles of education, psychology and public health to engage students with science for health literacy, focused on the message ‘Me, my health and my children’s health’. The program comprised a professional development day for teachers, a two to three week module of work for 13-14-year-olds and a ‘hands-on’ practical health science day visit to a dedicated facility in a university teaching hospital. Information was collected from 2929 adolescents aged 13-14 years, at baseline and 2487 at follow-up 12-months later.

“Experiencing LifeLab led to improved health literacy in adolescents and a move towards a more critical judgment of health behavior 12 months after the intervention,” said Dr. Kath Woods-Townsend, who leads the LifeLab program. “By providing opportunities linked to the National Curriculum, and which meet schools’ needs, we have shown that students can be successfully engaged with the science behind the health messages, with lasting benefits for their health literacy.”

Sharing her thoughts, Professor Hazel Inskip, principal investigator on the study from the Medical Research Council Lifecourse Epidemiology Unit at the University of Southampton, said: “The importance of health literacy in young people is being increasingly recognized, but there are very few randomized controlled trials seeking to assess interventions that promote health literacy through working in partnership with schools. It is an exciting step forwards to show that such a program can engage adolescents with science, leading to sustained changes in health literacy and more critical judgment of their own behavior.”
