A Systematic Review of Lifestyle Modifications to Improve Health and Well-Being Among Adolescents in the UK

Objectives: This study undertook a systematic review to evaluate how lifestyle changes can enhance the health and overall wellbeing of adolescents aged 10 to 19 years in the United Kingdom. The main aims were: (a) to explore the existing lifestyle patterns among UK adolescents, and (b) to assess the impact of targeted lifestyle modifications on this age group. Methods: A qualitative methodology was adopted, drawing exclusively on secondary data sources. The review was conducted using academic databases including Google Scholar, PubMed, and Medline. A total of ten relevant UK-based studies, all focusing on the specified adolescent age range, were included in the analysis. These studies employed varied research designs such as survey questionnaires, cross-sectional studies, web-based and online surveys, qualitative interviews, randomised controlled trials, longitudinal observational research, and quota sampling surveys. Thematic analysis was used to interpret the data. Results: Findings indicate that obesity rates among UK adolescents can be reduced through strategies such as improving sleep hygiene, integrating sleep education into school curricula, promoting healthy dietary habits, and encouraging positive behaviour changes. Conclusion: The review highlights that targeted lifestyle interventions can significantly enhance the health and wellbeing of UK adolescents. By addressing sleep, diet, and behavioural factors, schools and policymakers can play a crucial role in promoting healthier outcomes for young people.
