A systematic review of adolescent physiological development and its relationship with health-related behaviour: a protocol

Abstract

BackgroundAt any one time, there are one billion people worldwide who are in the second decade of their life, and 1.8 billion in the 10–24 age range.Whilst a great deal of focus has been placed on healthy early years development, the adolescent years are also a unique period of opportunity: exposure to health-influencing behaviours such as alcohol consumption or cigarette smoking, may serve to establish patterns that have significant health consequences in later life. Although there is often an emphasis on risk-taking and detrimental health behaviours during adolescence, these years also provide significant opportunities for behaviour to be shaped in positive ways that may improve longer term health outcomes. However, it is firstly important to understand the complex physiological changes that are taking place within the human body during this period and their relationship with health-related behaviour. Such knowledge can help to inform health policy and intervention development.AimThe aim of this study is to gain a comprehensive understanding of the relationship between physiological development and health-related behaviours in adolescence.MethodsThe principles of an integrative review will be used. Such reviews are of use where research has emerged in different fields, to combine existing knowledge and produce a more extensive understanding. Studies from a range of different methodological approaches, published or unpublished, will be included. A range of databases and literature depositories will be searched using a pre-defined search strategy. The review will include studies that focus on adolescents (nominally, those aged 10–24 years). We will seek papers that focus on both physiological development and health behaviour, or papers focusing solely on physiological development if there are clear implications for health behaviour. Studies with a focus on participants with specific health conditions will be excluded.Two reviewers will independently screen potential studies for eligibility and quality; members of the project team will act as third reviewers in the case of uncertainty or discrepancy.Further analyses (e.g. meta-analysis, meta-synthesis, meta-summary) will be decided upon, and sub-set analyses carried out. Finally, an integrative summation will be produced, giving a critical analysis of the results and providing conclusions and recommendations.Electronic supplementary materialThe online version of this article (doi:10.1186/s13643-015-0173-5) contains supplementary material, which is available to authorized users.

The physiology of adolescent sexual behaviour: A systematic review

“…A detailed review protocol and search strategy was developed and agreed between the project team and advisory group members (Pringle et al, 2016 ). In brief, we searched MEDLINE, Pubmed, PsycInfo, Embase, ERIC, ASSIA, Discovery, Cinahl, and Cochrane databases, using key words relating to adolescence and young adults, physiological development, and (sexual) health behaviours.…”

Stress Resilience in Late Adolescence and Survival among Cancer Patients: A Swedish Register-Based Cohort Study

“…High stress resilience in adults has been associated with longevity (14), while lower adaptive capacity for stress is linked with increased mortality (15). Poor stress resilience in adolescence, a transition period in the life course with profound impact on physiologic changes and establishment of behavioral patterns (16), has also been associated with increased allcause and cause-specific mortality in a general populationbased cohort of men (17). Although resilience can mitigate the consequences of activated neuroendocrine stress response pathways (2,3,13), possibly explaining some of the variation in disease outcomes in cancer patients with similar prognosis (3), no population-based study has to our knowledge yet examined stress resilience in relation to survival among cancer patients.…”

Exposure and attitudes to adolescent health amongst Paediatric trainees in Northern Ireland: a mixed-methods study

“…The mortality rate associated with adolescence remains high when compared with other age groups, with road traffic accidents, violence and self-harm the leading causes 3. While the perceived complexities associated with managing adolescent patients are well recognised, there exist unique opportunities to intervene in a positive manner with the potential to reduce the likelihood of developing a health condition in later life 4…”
