This study assesses the validity of home-measured height, weight and waist circumference among Finnish adolescents from the Fin-HIT cohort. The adolescents were measured by fieldworkers, and were instructed to measure themselves at home with an adult's assistance. Paired t-test was used for statistical analyses. Home-measured mean height, weight and waist circumference were slightly higher, but BMI lower than measured by the fieldworker. The difference in means was statistically significant for weight (0.51 kg) and waist circumference (1.6 cm), but not for height and BMI. Home-measured height, weight, waist circumference and BMI are sufficiently accurate to be used in epidemiologic studies.
