Work out obesity prevalence projection instantly with clear inputs, formula shown and shareable results.
Projects obesity prevalence forward with a linear annual increase in percentage points and converts it into case numbers.
Linear prevalence projection
Projected prevalence = current prevalence + annual increase in percentage points x years, bounded between 0 and 100%
Observed obesity trends have been close to linear in percentage points over recent decades, and a bounded projection avoids exceeding 100%.
Population-level dietary policy, GLP-1 receptor agonist availability and cohort effects all break simple extrapolation.
