How well we breathe as adults may depend on the amount of fat mass and lean body mass, or muscle, we have as children, according to a new study led by scientists from the Barcelona Institute for Global Health (ISGlobal), in a research that has been conducted as part of the Ageing Lungs in European Cohorts (ALEC) project, coordinated by Imperial College London.
"Some studies related higher body mass with higher lung function while others found higher body mass related to lower lung function", said Judith Garcia-Aymerich, senior study author and head of Non-communicable Diseases and Environment at ISGlobal. "We hypothesized that previous contradictory results could be attributed to the fact that overall body mass does not account for the different contribution of fat and muscle mass".
The study had 6,964 participants from the UK population-based Avon Longitudinal Study of Parents and Children (ALSPAC-) birth cohort, also known as the Children of the 90s longitudinal study.
"Our results highlight that body composition, and not just overall body mass, should be assessed when studying the health effects of weight in children", said Gabriela P. Peralta, ISGlobal researcher and first author of the study. "We believe that body composition in childhood and adolescence may play a role in future respiratory health", she added.
