The "fat-but-fit" paradigm has been evaluated. However, the duration of overweight/obesity within the "fat-but-fit" paradigm (ie, assessing body mass at more than 1 time point) has not been extensively evaluated, which was this study's purpose.
Cross-sectional.
National Health and Nutrition Examination Survey 2003 to 2006.
Ages 36 to 85; N = 3621.
Physical activity assessed via accelerometry. Medical multimorbidity was assessed via physician diagnosis of 13 chronic diseases. Height and body mass were directly measured for current body mass index (BMI), and 10-year prior BMI was calculated using current height and self-reported weight 10 years prior. Six mutually exclusive groups were created: (1) active, normal weight now and 10 years ago; (2) inactive, normal weight now and 10 years ago; (3) active, overweight/obese now but not 10 years ago; (4) active, overweight/obese now and 10 years ago; (5) inactive, overweight/obese now but not 10 years ago; and (6) inactive, overweight/obese now and 10 years ago.
Logistic regression.
Compared to group 1, adjusted odds ratios (ORs) were as follows: group 2: OR = 2.0 ( P = .004), group 3: OR = 1.7 ( P = .004), group 4: OR = 2.5 ( P < .001), group 5: OR = 2.9 ( P < .001), and group 6: OR = 4.8 ( P < .001).
All patterns of weight change/duration and activity level altered the odds of medical multimorbidity, suggesting that the duration of overweight/obesity should also be taken into consideration when assessing the "fat-but-fit" paradigm.
对“胖但健康”模式进行了评估。然而，“胖但健康”模式下超重/肥胖的持续时间（即多次评估体重）尚未得到广泛评估，这是本研究的目的。
横断面研究。
2003年至2006年全国健康与营养检查调查。
年龄36至85岁；N = 3621。
通过加速度计评估身体活动。通过医生对13种慢性病的诊断评估多种疾病并存情况。直接测量身高和体重以得出当前体重指数（BMI），并使用当前身高和10年前自我报告的体重计算10年前的BMI。创建了六个相互排斥的组：（1）活跃，现在和10年前体重正常；（2）不活跃，现在和10年前体重正常；（3）活跃，现在超重/肥胖但10年前不是；（4）活跃，现在和10年前都超重/肥胖；（5）不活跃，现在超重/肥胖但10年前不是；（6）不活跃，现在和10年前都超重/肥胖。
逻辑回归。
与第1组相比，调整后的优势比（OR）如下：第2组：OR = 2.0（P = .004），第3组：OR = 1.7（P = .004），第4组：OR = 2.5（P < .001），第5组：OR = 2.9（P < .001），第6组：OR = 4.8（P < .001）。
体重变化/持续时间和活动水平的所有模式都会改变多种疾病并存的几率，这表明在评估“胖但健康”模式时也应考虑超重/肥胖的持续时间。
