Note. Data were derived from the National Health Interview Survey 1987 Cancer Control Supplement File, 1989 Diabetes Supplement File, and 1995 Multiple Cause of Death File.^23–26 Analyses were limited to respondents aged between 18 and 64 years with available mortality, BMI, and smoking information. Data were weighted according to basic annual sampling weights. The BMI 20 to 25 category was the reference category (relative risk = 1).

Note. Data were derived from the 2002 National Health Interview Survey Sample Adult File.^23–26 Estimates were obtained from nonparametrically smoothed densities multiplied by sums of basic sample adult weights for 2002.

Note. Data were derived from the National Health Interview Survey 1987 Cancer Control Supplement File, 1989 Diabetes Supplement File, and 1995 Multiple Cause of Death File.^23–26 Plots represent predictions for an average individual at a given BMI according to semiparametric regression results (bandwidth = 0.15). All covariates other than BMI were treated parametrically. Analyses were limited to respondents aged between 18 and 64 years with available mortality, BMI, and smoking information. All mortality estimates were adjusted, via stratification, for race, age, limited smoking history, education level, income level, and marital status.
