“…However, several US and European studies [10][11][12][13][14][15][16] have shown that errors in self-reported weight and height underestimate the prevalence of overweight and obesity, and that measured obesity has a strong association with bias in selfreported BMI. Similar results are reported in this populationbased study.…”

“…[2][3][4][5][6] Several studies have shown high correlation between selfreported and measured BMI, [8][9][10] but systematic errors in selfreported values may affect the distribution of BMI, and consequently the prevalence of obesity. [10][11][12][13][14][15] The aims of our study were to evaluate the effect of misclassification of BMI in the association between obesity and asthma by gender.…”

Several recent studies have demonstrated a positive association between obesity and asthma among women but not men. The present study examines the effect of misclassification of body mass indes (BMI) in the association between obesity and asthma by gender. This cross-sectional analysis included a total sample of 961 Mexican adults. Use of measured BMI revealed that obesity (BMI 430 kg/m 2 ) was a risk factor for asthma diagnosis in both men (OR, 2.5; 95% CI, 1.1-5.9) and women (OR, 2.3; 95% CI, 1.5-3.8). In contrast, use of self-reported BMI showed that only women (OR, 1.7; 95% CI, 1.1-2.7) and not men (OR, 1.3; 95% CI, 0.6-2.9) were at increased risk of asthma diagnosis. Use of self-reported BMI substantially underestimated the prevalence of obesity; this bias was not related to asthma per se but was mainly due to obesity. Therefore, misclassification of BMI obscured the relationship between obesity and asthma to a greater extent among men than among women since obesity prevalence in the general population was higher among men. Measurement bias merits greater attention in future research on obesity and asthma.

“…Several studies have found systematic mis-reporting of weight and height in males and females of all adult ages, with those who are more overweight and shorter having a greater tendency to under Childhood intelligence, educational attainment and adult BMI DA Lawlor et al report their weight and over report their height. 27,28 This mis-reporting would need to have been more marked in those with higher intelligence test scores in childhood and greater educational attainment for it to explain the inverse associations that we have found. The similarity in our findings to those from two other prospective studies 9,10 with less loss to follow-up and that used actual measurements of weight and height to calculate BMI suggest that our results have not been markedly biased by loss to follow-up and use of self-report to assess height and weight.…”

Childhood intelligence, educational attainment and adult body mass index: findings from a prospective cohort and within sibling-pairs analysis

et al. 2006

Background:The mechanisms underlying the observed association of childhood intelligence with body mass index (BMI) are unclear and few studies of this association have been prospective in design. Methods: Prospective study in a birth cohort of 5467 individuals who were born in Aberdeen, Scotland between 1950 and 1956 and who responded to a follow-up survey in 2001. Comparison of associations within sibling pairs of the same family to associations between different families in 643 sibling pairs (1286 individuals) who are participants in the main cohort. Results: Childhood intelligence (age 7 years) and educational attainment were both inversely associated with adult BMI (mean age 48 years): the sex-and age-adjusted mean change in adult BMI per s.d. of intelligence was À0.35 kg/m 2 (95% CI: À0.49, À0.21 kg/m 2 ) and per unit increase in educational category (seven categories) was À0.28 kg/m 2 (95% CI: À0.34, À0.22). On adjustment for education the association between childhood intelligence and adult BMI attenuated to the null (À0.03 kg/m 2 (À0.19, 0.13 kg/m 2 )); other potential confounding or mediating factors had little or only modest effects on this association. The association between education and adult BMI was not affected by adjustment for childhood intelligence or other potential covariates. The within sibling-pair effect of education on adult BMI (À0.06 kg/m 2 (95% CI: À0.26, 0.14)) was weaker than the effect between different families (À0.37 kg/m 2 (95%CI: À0.58, À0.17)), P-value for difference of within sibling and between family effect ¼ 0.03. Conclusions: The association of childhood intelligence with adult BMI is attenuated to the null on adjustment for educational attainment, whereas the association of educational attainment with adult BMI appears to be independent of childhood intelligence and other measured covariates. However, our family analyses suggest that fixed family and neighbourhood factors, which are closely matched in siblings of a similar age, explain much of the association between greater educational attainment and lower adult BMI.

“…However, these findings are not always consistent (Hill & Roberts, 1998) and therefore the self-report of such measures may introduce bias, specifically if participants consistently over-or underestimated their height and weight resulting in skewed data. It is important to note that many of the participants availed themselves of the scale and height chart provided on the day of the survey, and the research team helped them to measure and then record their numbers.…”

Body mass index: a comparison between self-reported and measured height and weight

Abstract: Self-reported heights and weights are unreliable and if used for monitoring health targets should be treated with caution.
