A cross-cohort comparison of unhealthily low BMI in early adolescence – a feasibility study and development of research protocol (360G-Wellcome-200775_Z_16_Z)
Childhood thinness (unhealthily low body mass index) has been linked to poorer health and development but has received relatively little research attention in high income countries. Contemporary routine data reported by the National Child Measurement Programme (NCMP) point towards a possible U-shaped socio-economic gradient in thinness in 10-11 year olds (whereby those living in the most and least deprived areas have elevated rates of thinness). However, since the main focus of the NCMP is overweight and obesity, this social patterning in thinness has not been emphasised or further investigated. The U-shaped socio-economic distribution in thinness may be explained by food poverty in more disadvantaged areas, and issues of body image and eating disorders in more advantaged groups. UK cohort studies provide an untapped resource for examining this issue, because they contain rich, individual-level data, spanning different time periods (exposed to different social and economic contexts). However cross-cohort comparisons can be challenging and require a lot of input at the planning stage. This proposal therefore comprises of a feasibility study for a cross-cohort investigation of individual-level socio-economic inequalities in thinness in young people (and possible reasons behind them).
