Hypothesis
The study aims to evaluate the accuracy of self-reported weight, height, and waist circumference among a Dutch overweight working population.
Conclusion
Self-reported BMI and waist circumference are reasonably accurate for assessing overweight and obesity prevalence in a middle-aged overweight working population.
Supporting Evidence
- Body weight was under-reported by an average of 1.4 kg.
- Height was over-reported by an average of 0.7 cm.
- BMI was under-reported by 0.7 kg/m2.
- W waist circumference was over-reported by 1.1 cm.
- High concordance was found between measured and self-reported values.
Takeaway
People often guess their weight and height, and this study found that while they might not be perfect, their guesses are usually close enough to understand if they are overweight.
Methodology
The study involved 1298 overweight employees who reported their weight, height, and waist circumference, which were then compared to measured values.
Potential Biases
Self-reported measurements may be biased, particularly among heavier individuals and those with lower socioeconomic status.
Limitations
The study's findings may not be generalizable to non-employed overweight individuals or those with normal weight.
Participant Demographics
66.6% male, mean age 43.9 years, mean BMI 29.5 kg/m2.
