To examine the association between perceived overweight status and weight control, discrepancies between perceived and measured weight status, and opportunities for health care professionals (HCPs) to correct weight perception among US adults.
Population-based cross-sectional study.
In all, 16,720 non-pregnant adults from the 2003 to 2008 National Health and Nutrition Examination Survey.
Overall, 64% (73% women, 55% men) reported a desire to weigh less and 48% (57% women, 40% men) reported pursuing weight control. Weight control was positively associated with overweight perception (odds ratio (OR) women 3.74; 95% confidence interval (CI) 2.96, 4.73; OR men 2.82; 95% CI 2.11, 3.76) and an HCP diagnosis of overweight/obesity (OR women 2.22; 95% CI 1.69, 2.91; OR men 2.14; 95% CI 1.58, 2.91), independent of measured weight status. A large proportion of overweight individuals (23% women, 48% men) perceived themselves as having the right weight. Also, 74% of overweight and 29% of obese individuals never had an HCP diagnosis of overweight/obesity. Although the majority of overweight/obese individuals (74% women, 60% men) pursued at least one weight management strategy, fewer (39% women, 32% men) pursued both dietary change and physical activity. Among overweight/obese adults, those with an HCP diagnosis of overweight/obesity were more likely to diet (74 versus 52%), exercise (44 versus 34%), or pursue both (41 versus 30%, all P<0.01) than those who remained undiagnosed.
HCPs have unused opportunities to motivate their patients to control and possibly lose weight by correcting weight perceptions and offering counseling on healthy weight loss strategies.
研究美国成年人超重认知与体重控制、自我感知体重与实际体重的差异以及保健专业人员（HCPs）纠正体重认知的机会之间的关联。
基于人群的横断面研究。
共纳入来自 2003 至 2008 年全国健康与营养调查的 16720 名非孕妇成年人。
总体而言，64%（女性占 73%，男性占 55%）报告希望体重减轻，48%（女性占 57%，男性占 40%）正在进行体重控制。体重控制与超重认知呈正相关（女性比值比（OR）3.74；95%置信区间（CI）2.96，4.73；男性 OR 2.82；95% CI 2.11，3.76）和 HCP 超重/肥胖诊断（女性 OR 2.22；95% CI 1.69，2.91；男性 OR 2.14；95% CI 1.58，2.91），独立于实际体重状态。相当一部分超重者（女性占 23%，男性占 48%）认为自己体重正常。此外，74%的超重者和 29%的肥胖者从未被 HCP 诊断为超重/肥胖。尽管大多数超重/肥胖者（女性占 74%，男性占 60%）至少采取了一种体重管理策略，但采取饮食改变和体育活动的人数较少（女性占 39%，男性占 32%）。在超重/肥胖成年人中，被 HCP 诊断为超重/肥胖的人更有可能节食（74%对比 52%）、运动（44%对比 34%）或同时进行节食和运动（41%对比 30%，所有 P<0.01），而那些未被诊断的人则较少进行这些行为。
HCPs 有机会通过纠正体重认知和提供健康减肥策略咨询来激励患者进行体重控制并可能减轻体重。
