Little is known about weight control strategies associated with successful weight loss among obese U.S. adults in the general population.
To identify strategies associated with losing at least 5% and 10% of body weight.
Multivariable analysis of data from obese adult (BMI ≥30) participants in the 2001-2006 NHANES to identify strategies associated with losing ≥5% and ≥10% of body weight (conducted in 2009-2011).
Of 4021 obese adults, 2523 (63%) reported trying to lose weight in the previous year. Among those attempting weight loss, 1026 (40%) lost ≥5% and 510 (20%) lost ≥10% weight. After adjustment for potential confounders, strategies associated with losing ≥5% weight included eating less fat (OR=1.41, 95% CI=1.14, 1.75); exercising more (OR=1.29, 95% CI=1.05, 1.60); and using prescription weight loss medications (OR=1.77, 95% CI=1.00, 3.13). Eating less fat (OR=1.37, 95% CI=1.04, 1.79); exercising more (OR=1.36, 95% CI=1.12, 1.65); and using prescription weight loss medications (OR=2.05, 95% CI=1.09, 3.86) were also associated with losing ≥10% weight, as was joining commercial weight loss programs (OR=1.72, 95% CI=1.00, 2.96). Adults eating diet products were less likely to achieve 10% weight loss (OR=0.48, 95% CI=0.31, 0.72). Liquid diets, nonprescription diet pills, and popular diets had no association with successful weight loss.
A substantial proportion of obese U.S. adults who attempted to lose weight reported weight loss, at least in the short term. Obese adults were more likely to report achieving meaningful weight loss if they ate less fat, exercised more, used prescription weight loss medications, or participated in commercial weight loss programs.
在美国一般人群中，肥胖成年人成功减肥所采取的体重控制策略鲜为人知。
确定与至少减轻 5%和 10%体重相关的策略。
对 2001-2006 年 NHANES 中肥胖成年人（BMI≥30）参与者的数据进行多变量分析，以确定与至少减轻 5%和 10%体重相关的策略（于 2009-2011 年进行）。
在 4021 名肥胖成年人中，2523 名（63%）报告在过去一年中试图减肥。在那些试图减肥的人中，1026 名（40%）减轻了≥5%的体重，510 名（20%）减轻了≥10%的体重。在调整潜在混杂因素后，与减轻≥5%体重相关的策略包括减少脂肪摄入（OR=1.41，95%CI=1.14，1.75）；更多锻炼（OR=1.29，95%CI=1.05，1.60）；和使用处方减肥药（OR=1.77，95%CI=1.00，3.13）。减少脂肪摄入（OR=1.37，95%CI=1.04，1.79）；更多锻炼（OR=1.36，95%CI=1.12，1.65）；和使用处方减肥药（OR=2.05，95%CI=1.09，3.86）也与减轻≥10%的体重有关，参加商业减肥计划（OR=1.72，95%CI=1.00，2.96）也是如此。食用饮食产品的成年人不太可能达到 10%的体重减轻（OR=0.48，95%CI=0.31，0.72）。液体饮食、非处方减肥药和流行饮食与成功减肥无关。
相当比例的美国肥胖成年人试图减肥，至少在短期内体重有所减轻。如果肥胖成年人减少脂肪摄入、增加锻炼、使用处方减肥药或参加商业减肥计划，他们更有可能报告实现有意义的体重减轻。
