#BeeWell was co-developed with young people to address concerns regarding the well-being of young people in the United Kingdom. The study uses a hybrid population cohort design with two main elements: a truncated longitudinal study of participants tracked with annual data points from age 12 to 15 (i.e., from Year 8 to Year 9 to Year 10 of secondary school; sample 1); and a serial cross-sectional study comprising annual data points for participants aged 14 to 15 (i.e., those in Year 10 of secondary school at a given data point; sample 2). #BeeWell is ongoing in two locations: Greater Manchester (GM) and Hampshire, including the Isle of Wight, Portsmouth, and Southampton (HIPS). In #BeeWell - GM 2, sample 1 includes over 36,000 adolescents aged 11 to 12 years at baseline from 147 secondary schools across Greater Manchester, England. Data collection began in 2024, and follow-up and recruitment for this cohort are ongoing.
