目的：要研究的BMI与功能状态和自我评价的健康在美国成年人之间的关联，以及如何协会不同的年龄和sex.Methods和程序：所有的分析是基于全国健康访谈调查（NHIS），1997-2005年，每年一次，美国家庭人口的代表性研究。我们汇总了所有调查年份，并为两种性别和三个年龄层（年龄18-44岁，45-64岁，≥ 65岁）进行了logistic回归分析。结果：我们的研究发现，尽管体重不足和严重肥胖始终与残疾增加和健康状况较差相关，但超重和中度肥胖显示出随年龄和性别而变化的相关性。对于男性，残疾和较差/一般自评健康的调整后比值比（OR）在超重人群中往往最低，尤其是年龄>= 45岁的人群。在中度肥胖的男性中，18-44岁的残疾风险升高，但年龄>= 65岁的残疾风险较低。对于女性来说，残疾和健康状况差/一般的自我评价的调整OR在体重正常的人群中往往是最低的，特别是对于年龄>= 45岁的人群。与正常体重的女性相比，年龄≥ 65岁的超重女性残疾的风险较低，但风险稍高的差/公平的自我评价health.Discussion：结果表明，BMI与功能状态和自我评价健康的关联在不同年龄和性别之间存在显着差异。BMI与功能状态和自评健康状况之间的关联变化表明，单一的“理想体重类别”可能不适合所有人或所有健康结果。
Objective: To examine the association of BMI with functional status and self-rated health among US adults and how the association differs by age and sex.Methods and Procedures: All analyses are based on the National Health Interview Survey (NHIS), 1997-2005, a yearly, representative study of the US household population. We pooled all survey years and fitted logistic regression for the two sexes and three age strata (ages 18-44, 45-64, and >= 65).Results: Our study found that although underweight and severe obesity are consistently associated with increased disability and poorer health status, overweight and moderate obesity show associations that vary considerably by age and sex. For men, the adjusted odds ratios (ORs) for disability and poor/fair self-rated health tended to be lowest among overweight persons, especially for ages >= 45. Among men with moderate obesity, the risk of disability was elevated for ages 18-44 but lower for ages >= 65. For women, the adjusted ORs for disability and poor/fair self-rated health tended to be lowest among normal-weight persons, particularly for ages >= 45. Compared to normal-weight counterparts, overweight women aged >= 65 had a lower risk of disability but a somewhat elevated risk of poor/fair self-rated health.Discussion: The results suggest that the association of BMI with functional status and self-rated health varies significantly across ages and sexes. The variations in the association of BMI with functional status and self-rated health suggest that a single "ideal body weight category" may not be appropriate for all persons or all health outcomes.
