Associations (β –coefficients; 95% CI) between birth weight and adult hand grip strength or fat-free mass in all individuals.

Model 1 –model adjusted for gestational age, adult age (and sex when analyses was carried out in men and women together).Model 2 –model adjusted for gestational age, adult age, (sex) and adult height.Model 3 – adjusted for gestational age, adult age, (sex) and adult fat free mass.Linear regression models β coefficients represent change in adult hand grip strength (kg) or adult fat free mass (kg) per 1 kg change in birth weight, with 95% Confidence Intervals.
