“…Self-report of birth weight in adults is moderately correlated with hospital records (33). Correlations between self-report of birth weight and anthropometric measures in the women in this study were of the magnitude expected from previous studies in which medically recorded birth weights have been used (8).…”

OBJECTIVE -To assess the independent associations of a broad range of early life risk factors and adult obesity with adult insulin resistance.RESEARCH DESIGN AND METHODS -This was a cross-sectional study of 1,394 women, aged 60 -79 years, from 23 British towns.RESULTS -There was a strong (independent of confounding factors, other early life factors, and adult waist-to-hip ratio) inverse association between birth weight and insulin resistance in women in the highest third of BMI (Ͼ28.77 kg/m 2 ): Ϫ0.12 (95% CI Ϫ0.19 to Ϫ0.04) log homeostasis model assessment (HOMA) score per 1 SD birth weight, but no association between birth weight and insulin resistance in women in the two lowest thirds of BMI (P for interaction ϭ 0.04). Offspring birth weight, own leg length, and childhood manual social class did not interact with adult obesity and were all independently inversely associated with insulin resistance: Ϫ0.05 (Ϫ0.09 to Ϫ0.01) log HOMA score per 1 SD offspring birth weight, Ϫ0.09 (Ϫ0.12 to Ϫ0.06) log HOMA score per 1 SD leg length, and a Ϫ0.07 (Ϫ0.14 to 0.00) difference in log HOMA score between manual and nonmanual childhood social class. Childhood manual social class and shorter leg length were both independently associated with adverse lipid profiles. BMI and waist-to-hip ratio were independently positively associated with insulin resistance and with all other components of the insulin resistance syndrome.CONCLUSIONS -Insulin resistance is an important risk factor for type 2 diabetes and coronary heart disease. Our results suggest that genetic factors, intrauterine environment, early childhood, and adult environmental factors are all relevant in determining adult insulin resistance. Diabetes Care 26:97-103, 2003S everal lines of research suggest that the pathogenesis of both type 2 diabetes and coronary heart disease begin in early life. Autopsy studies of U.S. combatants killed in the Korean and Vietnamese wars found that 77 and 45%, respectively, of the young men in these studies (mean age 22 years) had atherosclerosis (1,2). Low birth weight (3,4), childhood social class (5), and adult leg length (an indicator of childhood environmental exposures (6 -8) have all been found to predict type 2 diabetes and coronary heart disease in later life. Insulin resistance appears to be an important mediating factor in all of these associations.One explanation for the association between low birth weight and both type 2 diabetes and coronary heart disease is that poor intrauterine nutrition leads to not only small birth size but also, depending upon the timing of the nutritional deprivation, to "program" changes in glucoseinsulin metabolism leading to insulin resistance and increased diabetes and coronary heart disease risk in later life (9).An alternative theory, the fetal insulin hypothesis, suggests that genetic polymorphisms that lead to both increased insulin resistance and insulin-mediated impaired fetal growth underlie the association between birth weight and diabetes and coronary heart disease (4,10). This latter h...

“…A limitation of this study is that BW was self-reported. However, findings from other studies have shown that recalled BW is valid and reproducible and showed correlations between 0.6 and 0.8 with recorded BW (39)(40)(41)(42)(43). Only 73% of the sample reported their BW; however, there were no differences in body composition variables between those who reported BW and those who did not report BW (data not shown).…”

Background: Several studies reported inverse associations between birth weight and central adiposity in adults. However, few studies investigated the contributions of different abdominal fat compartments. Objective: We examined associations between birth weight and adult visceral and subcutaneous abdominal fat in the populationbased Fenland study. Design: A total of 1092 adults (437 men and 655 women) aged 30-55 y had available data on reported birth weight, standard anthropometric measures, and visceral and subcutaneous abdominal fat estimated by ultrasound. In a subgroup (n = 766), dual-energy Xray absorptiometry assessment of total abdominal fat was performed. Linear regression models were used to analyze relations between birth weight and the various fat variables adjusted for sex, age, education, smoking, and body mass index (BMI). Results: After adjustment for adult BMI, there was an inverse association between birth weight and total abdominal fat [B (partial regression coefficient expressed as SD/1-kg change in birth weight) = 20.09, P = 0.002] and visceral fat (B = 20.07, P = 0.01) but not between birth weight and subcutaneous abdominal fat (B = 20.01, P = 0.3). Tests for interaction showed that adult BMI modified the association between birth weight and visceral fat (P for interaction = 0.01). In stratified analysis, the association between birth weight and visceral fat was apparent only in individuals with the highest BMI tertile (B = 20.08, P = 0.04). Conclusions: The inverse association between birth weight and adult abdominal fat appeared to be specific to visceral fat. However, associations with birth weight were apparent only after adjustment for adult BMI. Therefore, we suggest that rapid postnatal weight gain, rather than birth weight alone, leads to increased visceral fat.Am J Clin Nutr 2010;92:347-52.

“…First, birth weight data were based on self-report. Previous studies have shown moderate correlations between estimated and recorded birth weight (r = 0.64–0.83)505152. We expect but cannot confirm that misclassification of birth weight in our study of older adults, if present, would be non-differential with respect to diabetes, and therefore likely underestimate the strength of association reported.…”

Emerging evidence suggests sex differences in the early origins of adult metabolic disease, but this has been little investigated in developing countries. We investigated sex-specific associations between low birth weight (LBW; <2.5 kg) and adult-onset diabetes in 12,525 participants from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Diabetes was defined by self-reported information and laboratory measurements. In confounder-adjusted analyses, LBW (vs. 2.5–4 kg) was associated with higher prevalence of diabetes in women (Prevalence Ratio (PR) 1.54, 95% CI: 1.32–1.79), not in men (PR 1.06, 95% CI: 0.91–1.25; Pheterogeneity = 0.003). The association was stronger among participants with maternal diabetes (PR 1.60, 95% CI: 1.35–1.91), than those without (PR 1.15, 95% CI: 0.99–1.32; Pheterogeneity = 0.03). When jointly stratified by sex and maternal diabetes, the association was observed for women with (PR 1.77, 95% CI: 1.37–2.29) and without (PR 1.45, 95% CI: 1.20–1.75) maternal diabetes. In contrast, in men, LBW was associated with diabetes in participants with maternal diabetes (PR 1.45, 95% CI: 1.15–1.83), but not in those without (PR 0.92, 95% CI: 0.74–1.14). These sex-specific findings extended to continuous measures of glucose homeostasis. LBW was associated with higher diabetes prevalence in Brazilian women, and in men with maternal diabetes, suggesting sex-specific intrauterine effects on adult metabolic health.
