  12. Background The relation between body weight and mortality among persons with type 2 diabetes remains unresolved, with some studies suggesting decreased mortality among overweight or obese persons as compared with normal-weight persons (an “obesity paradox”).

  13. Methods We studied participants with incident diabetes from the Nurses' Health Study (8970 participants) and Health Professionals Follow-up Study (2457 participants) who were free of cardiovascular disease and cancer at the time of a diagnosis of diabetes. Body weight shortly before diagnosis and height were used to calculate the body-mass index (BMI, the weight in kilograms divided by the square of the height in meters). Multivariable Cox models were used to estimate the hazard ratios and 95% confidence intervals for mortality across BMI categories.

  14. Figure 2. Hazard Ratios for Cause-Specific Mortality among Participants with Incident Type 2 Diabetes, According to BMI Shortly before Diagnosis of Type 2 Diabetes. The results from the two cohorts (NHS and Health Professionals Follow-up Study) were combined with the use of a fixed-effect meta-analysis. The numbers of person-years were 179,081 for all participants, 79,546 for those who had never smoked, and 97,762 for those who had ever smoked. Panel A shows cardiovascular mortality in the total study population (941 deaths), among participants who had never smoked (340 deaths), and among those who had ever smoked (592 deaths). Panel B shows cancer mortality in the total study population (784 deaths), among participants who had never smoked (266 deaths), and among those who had ever smoked (514 deaths). Panel G shows mortality from other causes in the total study population (1358 deaths), among participants who had never smoked (561 deaths), and among those who had ever smoked (786 deaths). All estimates have been adjusted for age, race, marital status, menopausal status (for the NHS cohort only), presence or absence of a family history of diabetes, smoking status (among all participants and those who had ever smoked), alcohol intake, and Alternate Healthy Eating Index score. A total of 20 women and 79 men with missing data on smoking status were excluded from the stratified analyses (24 total deaths, including 9 from cardiovascular causes, 4 from cancer, and 11 from other causes). The bars represent 95% confidence intervals.

  15. Results There were 3083 deaths during a mean period of 15.8 years of follow-up. A J-shaped association was observed across BMI categories (18.5 to 22.4, 22.5 to 24.9 [reference], 25.0 to 27.4, 27.5 to 29.9, 30.0 to 34.9, and ≥35.0) for all-cause mortality (hazard ratio, 1.29 [95% confidence interval {CI}, 1.05 to 1.59]; 1.00; 1.12 [95% CI, 0.98 to 1.29]; 1.09 [95% CI, 0.94 to 1.26]; 1.24 [95% CI, 1.08 to 1.42]; and 1.33 [95% CI, 1.14 to 1.55], respectively). This relationship was linear among participants who had never smoked (hazard ratios across BMI categories: 1.12, 1.00, 1.16, 1.21, 1.36, and 1.56, respectively) but was nonlinear among participants who had ever smoked (hazard ratios across BMI categories: 1.32, 1.00, 1.09, 1.04, 1.14, and 1.21) (P=0.04 for interaction). A direct linear trend was observed among participants younger than 65 years of age at the time of a diabetes diagnosis but not among those 65 years of age or older at the time of diagnosis (P<0.001 for interaction).

  16. Conclusions We observed a J-shaped association between BMI and mortality among all participants and among those who had ever smoked and a direct linear relationship among those who had never smoked. We found no evidence of lower mortality among patients with diabetes who were overweight or obese at diagnosis, as compared with their normal-weight counterparts, or of an obesity paradox.

  17. Message 心血管疾患と癌のない2型糖尿病（DM）患者1万1427人を対象に、BMIと死亡率の関連を多変量Coxモデルで解析。平均15.8年の追跡調査で、BMI区分と全死因死亡率にJ字型の関連が見られたが、非喫煙者では線形だった。過体重・肥満者のDM患者が正常体重の患者よりも死亡率が低いという「肥満パラドックス」は見られなかった。
