Types of greenspace and adolescent mental health and well-being in metropolitan London

The evidence suggests a link between greenspace and adolescent mental health. One limitation is the typically crude measure of quantity or greenness. We explored roles different types in health 10- to 15-year-old adolescents living London, using data from Understanding Society, UK household longitudinal study. used on 1,879 waves 1-8 (2009-2018). As some had observations at multiple waves, 4,217 were included. Mental well-being measures Strengths Difficulties Questionnaire scores, self-esteem, happiness. Proportions green land cover, parks & gardens, natural semi-natural urban greenspaces, outdoor sports facilities, total use measured 500 m around postcodes. ran linear regressions, stratified by age, adjusted for confounders, accounting Society’s complex sampling design. did not find consistent results across analyses, but we identified patterns worth exploring further: older (13-15 years) seemed ‘benefit’ more than younger (10-12 years); gardens facilities be most ‘beneficial’. Overall, however, no clear conclusions can drawn, findings need confirmed future studies.
