Regional differences in self-reported body dimensions
Self-reported values of height and weight are used increasingly despite warnings that these data might be biased. The present study investigates whether differences between self-reported and measured values are the same for populations from different regions, and the influences of gender and age. Differences between self-reported and measured weights and heights are compared for representative samples of the adult population of Italy, the Netherlands and North America. In general, weight is under-reported (1.1 ± 2.6 kg for females and 0.4 ± 3.1 kg for males) and height overreported (1.1 ± 2.2 cm for females and 1.7 ± 2.1 cm for males), in accordance with the literature. Italy shows most over-reporting of height (2.6 ± 1.9 cm) and least under-reporting in weight (0.4 ± 2.4 kg). The Dutch show least over-reporting of height (1.0 ± 2.2 cm) and most under-reporting of weight (1.1 ± 3.2 kg). North America is in between with 1.2 ± 2.1 cm and 0.7 ± 2.9 kg. Furthermore, there are substantial differences between age groups (18-30, 31-45 or 46-65 years). Height is over-reported more by younger and (even more markedly) by older people, while older persons in Italy and the Netherlands under-report their weights more than the other age groups. Detailed inspection of the data also reveals differences between small and tall and between light and heavy weighted persons. Height is over-estimated most by small men and women and weight is under-reported most by heavy people (“light weights even over-report their weights). Apart from a general overestimation of height and underestimation of weight, substantial differences are observed between countries, between females and males, and between age groups. The supplied tables enable correction, based on country, gender, and age group, of self-reported values.
