To evaluate the association between BMI: kg/m(2) and mortality among Hispanic adults.
Eight years (1997-2004) of National Health Interview Survey data linked to public-use mortality follow-up data through 2006 were acquired. Using Cox proportional hazards regression, separate models for two attained age strata (18 to <60 years, ≥60 years) adjusting for sex, smoking, and physical activity with over 38,000 analyzable respondents were fit.
Among those aged ≥60 years, underweight (BMI ≤ 18.5) associated with elevated mortality (hazard ratio [HR] = 2.19; 95% confidence interval [CI], 1.38-3.46), whereas overweight (BMI of 25 to <30) and obesity grade 1 (BMI of 30 to <35) associated with reduced mortality (HRs = 0.79; 95% CI, 0.65-0.95 and 0.71; 95% CI, 0.56-0.91), respectively. There were no significant associations between BMI and mortality among the 18 to <60 years attained age strata or among never smokers for either age strata.
Overweight and obesity are not obviously associated with elevated mortality among Hispanic adults.
评估 BMI（kg/m(2)）与西班牙裔成年人死亡率之间的关联。
获取了 1997 年至 2004 年 8 年的全国健康访谈调查数据，并与 2006 年之前的公共使用死亡率随访数据进行了链接。使用 Cox 比例风险回归，对两个达到年龄层（18 岁至<60 岁，≥60 岁）分别进行调整，以性别、吸烟和体力活动为协变量，对超过 38000 名可分析的受访者进行了拟合。
在≥60 岁的人群中，体重过轻（BMI≤18.5）与死亡率升高相关（危险比[HR] = 2.19；95%置信区间[CI]，1.38-3.46），而超重（BMI 为 25 至<30）和肥胖 1 级（BMI 为 30 至<35）与死亡率降低相关（HRs = 0.79；95%CI，0.65-0.95 和 0.71；95%CI，0.56-0.91）。在 18 岁至<60 岁的达到年龄层或在两个年龄层的从不吸烟者中，BMI 与死亡率之间均无显著关联。
超重和肥胖与西班牙裔成年人死亡率升高无关。
