To determine the aspects of quality of life that are affected by weight in the general population, to develop a specific questionnaire (OSQOL) that can measure with reliability and validity the impact of overweight and obesity on well being, and to compare the results with those obtained using a well known generic tool (the "SF 36" scale).
Cross sectional survey with matched control group.
Community.
A permanent survey base of approximately 10,000 representative ordinary households were screened for weight and height. Five hundred subjects were randomly drawn from the sub-sample of adult people with a body mass index equal or greater than 27. A control sample of 500 subjects matched for sex, age, and employment status was drawn from the non-obese population.
A short specific Quality Of Life scale, the OSQOL, was produced that comprises 11 items belonging to four independent dimensions. Using this scale and the SF36, it was found that: (1) moderately obese subjects (27 < or = BMI < 30) did not significantly differ from the control group except for physical capacity; (2) in the group of obese subjects with a BMI > 30, quality of life seemed to be impaired for five of nine dimensions of the SF36 compared with the control population, all related to physical consequences of obesity. This population essentially perceived itself in terms of poor general health. (3) No significant difference was observed between the samples for the psychological and social dimensions of the SF36.
The quality of life of patients with severe obesity is impaired, but it mainly affects the physical consequences of the disease. The psychological and social repercussions that could have been expected to affect this population were not demonstrated. The hypothesis of a process of adaptation of the person and their social environment cannot therefore be excluded. Methodologically, comparison of the specific OSQOL with the generic SF3 shows clearly that the two kinds of scales correspond to different objectives and should be considered as complementary.
确定普通人群中受体重影响的生活质量方面，开发一种能可靠且有效测量超重和肥胖对幸福感影响的特定问卷（OSQOL），并将结果与使用知名通用工具（“SF 36”量表）所得结果进行比较。
设有匹配对照组的横断面调查。
社区。
对约10000个具有代表性的普通家庭的永久调查样本进行体重和身高筛查。从体重指数等于或大于27的成年人子样本中随机抽取500名受试者。从不肥胖人群中抽取500名在性别、年龄和就业状况上匹配的对照样本。
编制了一个简短的特定生活质量量表OSQOL，它由属于四个独立维度的11个项目组成。使用该量表和SF36发现：（1）中度肥胖受试者（27≤体重指数＜30）除身体能力外与对照组无显著差异；（2）在体重指数＞30的肥胖受试者组中，与对照人群相比，SF36九个维度中的五个维度的生活质量似乎受损，所有这些都与肥胖的身体后果有关。该人群基本上认为自己总体健康状况较差。（3）在SF36的心理和社会维度上，样本之间未观察到显著差异。
重度肥胖患者的生活质量受损，但主要影响疾病的身体后果。预期会影响该人群的心理和社会影响未得到证实。因此不能排除个体及其社会环境适应过程的假设。从方法学上讲，特定的OSQOL与通用的SF3的比较清楚地表明，这两种量表对应不同的目标，应被视为互补。
