- Abstract
Self-reported body weight and height, due to its cost-effectiveness and the convenience of data collection, are often used to determine body mass index as the most important indicator of obesity. The study aims to examine the validity body mass index based on self-reported data of the 2014 Hungarian Diet and Nutritional Status Survey (OTÁP) for the Hungarian adult population. Despite the fact that the measured and self-reported body mass index is highly correlated with each other, the matched-pairs signed rank test indicated a significant difference between the two methods of measurement. We have identified different components of the bias of self-reported data. People with low body weight have a tendency to overestimate their BMI value, and obese people to underestimate it. From the traditional socio-demographic variables only marital status and gender played a significant role in the difference of the measured and the declared values, and in the case of males, not even the marital status was significant. Measured and self-reported obesity groups resulted not significant risk of diabetes.
