PAFs with 95% CIs for later disability by cause associated with lower physical fitness (see online supplementary table 2 for exact estimates and confidence intervals). ¹PAF is adjusted for conscription year, age, childhood socioeconomic position and BMI at conscription. Models with disability pension due to all or psychiatric causes were also adjusted for any mental hospitalisation before conscription and for any psychiatric diagnosis at conscription. ²Fitness levels were categorised by deciles of cardiorespiratory fitness. Decile 1 ≤211 Watts; decile 2=212–229 Watts; decile 3=230–241 Watts; decile 4=242–254 Watts; decile 5=255–270 Watts; decile 6=271–284 Watts; decile 7=285–300 Watts; decile 8=301–320 Watts; decile 9=321–343 Watts; decile 10 ≥344 Watts. ³If unfit participants (ie, deciles 1–2) were to become fit (ie, deciles 3–10). ⁴If all participants with a fitness level in deciles 1–9 were to increase their fitness by 1 decile. BMI, body mass index; PAF, population attributable fraction.
