“…Measured BMI tends to be underreported by self report, especially for women with a higher body weight [18]. For overweight and obese women the mean difference was -1.14 BMI [19]. This would only strengthen our findings as the threshold of BMI where mortality hazards start to increase (see Fig.…”

The evidence of effect of overweight and obesity on mortality at middle and old age is conflicting. The increased relative risk of cardiovascular disease and diabetes for overweight and obese individuals compared to normal weight is well documented, but the absolute risk of cardiovascular death has decreased spectacularly since the 1980s. We estimate the burden of mortality of obesity among middle and old aged adults in the Health and Retirement Survey (HRS), a US prospective longitudinal study. We calculate univariate and multivariate age-specific probabilities and proportional hazard ratios of death in relation to self-reported body mass index (BMI), smoking and education. The life table translates age specific adjusted event rates in survival times, dependent on risk factor distributions (smoking, levels of education and self reported BMI). 95% confidence intervals are calculated by bootstrapping. The highest life expectancy at age 55 was found in overweight (BMI 25-29.9), highly educated non smokers: 30.7 (29.5-31.9) years (men) and 33.2 (32.1-34.3) (women), slightly higher than a BMI 23-24.9 in both sexes. Smoking decreased the population life expectancy with 3.5 (2.7-4.4) years (men) and 1.8 (1.0-2.5) years (women). Less than optimal education cost men and women respectively 2.8 (2.1-3.6) and 2.6 (1.6-3.6) years. Obesity and low normal weight decreased population life expectancy respectively by 0.8 (0.2-1.3) and 0.8 (0.0-1.5) years for men and women in a contemporary, US population. The burden of mortality of obesity is limited, compared to smoking and low education.

“…First, self-reported BMI was used for trajectory calculation. Individuals are known to overreport height and underreport weight (Nawaz, Chan, Abdulrahman, Larson, & Katz, 2001). As such, self-reported BMI tends to reflect a conservative estimate of the “true” BMI.…”

Objectives To evaluate latent heterogeneity in long-term trajectories of body weight in older adults. Methods We analyzed 14-year longitudinal data on 10,314 older adults from the Health and Retirement Study. Semiparametric mixture models identified latent subgroups of similar trajectories of body mass index (BMI). Results Five distinct trajectory subgroups emerged: normal starting-BMI with accelerated increase over time (trajectory #1), overweight and increasing (trajectory #2), borderline-obese and increasing (trajectory #3), obese and increasing (trajectory #4), and morbidly obese with decelerating gain (trajectory #5). Blacks and Hispanics had greater risk of membership in ascending high-BMI trajectory groups. Females had approximately half the risk of following overweight and obese increasing BMI trajectories compared with males. Discussion Distinct latent subgroups of BMI trajectories and significant racial/ethnic and gender trajectory heterogeneity exist in the older adult population. The propensity of men and minorities to experience high-risk BMI trajectories may exacerbate existing disparities in morbidity/ mortality in older age.

“…12 In contrast, we measure the height and weight of each participant, avoiding the potential problems with self-reported data and providing a clean measure of BMI. Self-reported height and weight can misrepresent BMI since weight is frequently under-reported and height over-reported, especially among unemployed women (e.g., Nawaz et al ., 2001). We also differ in the specification of the dependent variable.…”

Obesity has reached epidemic proportions in the US, with a significantly higher fraction of African Americans who are obese than whites. Yet there is little understanding of why some individuals become obese while others do not. We conduct a lab-in-field experiment in a low-income African American community to investigate whether risk and time preferences play a role in the tendency to become obese. We examine the relationship between incentivized measures of risk and time preferences and weight status (BMI), and find that individuals who are more tolerant of risk are more likely to have a higher BMI. This result is driven by the most risk tolerant individuals. Patience is not independently statistically related to BMI in this sample, but those who are more risk averse and patient are less likely to be obese.
