在大多数涉及老年受试者的前瞻性研究中，体重减轻与死亡率增加相关。作者调查了来自24个城镇的中年男性的特征和健康状况（英国地区心脏研究），他们报告说，随着年龄的增长，他们有意或无意地减肥。在筛选时（1978-1980年）、5年后以及1992年和1996年完成了问卷调查。本文涉及4,713名男性，他们在1992年和1996年报告了自己的体重，以及在此期间他们感知的体重变化。847名男性（18%）报告体重减轻，其中39%表示这是故意的。与有意减肥相比，无意减肥与较低的社会阶层、更多的吸烟、更少的肥胖和更少的体育活动有关，并且与“健康状况不佳“、长期残疾、癌症和呼吸系统疾病的发生率最高有关。回忆性心脏病发作、中风、糖尿病和心血管住院的发生率高于体重稳定的男性。有意减肥的男性比无意减肥的男性更肥胖，并且有更高的肥胖相关疾病的发生率。因此，有意和无意的体重减轻都可能伴随着疾病的发展。这些发现可能解释了在大多数大规模前瞻性研究中观察到的缺乏益处和与体重减轻相关的死亡率增加。
In most prospective studies involving older subjects, weight loss is associated with increased mortality. The authors examined the characteristics and health status of middle-aged men from 24 towns (the British Regional Heart Study), who reported that they had lost weight intentionally or unintentionally as they aged. Questionnaires were completed at screening (1978-1980), 5 years later, and in 1992 and 1996. This paper concerns the 4,713 men who reported their weight in 1992 and 1996 and their perceived weight change over this period. Weight loss was reported by 847 men (18%), of whom 39% stated that it was intentional. Compared with intentional weight loss, unintentional weight loss was associated with lower social class, more smoking, less obesity, and less physical activity and with the highest rates of "poor health,"long-standing disability, cancer, and respiratory diseases. The rates of recalled heart attack, stroke, diabetes, and cardiovascular hospitalization were higher than among men whose weight was stable. Men who lost weight intentionally had been more obese than those who lost weight unintentionally and had high rates of obesity-related conditions. Thus, both intentional and unintentional weight loss may follow the development of disease. These findings probably account for the lack of benefit and the increased mortality associated with weight loss observed in most large-scale prospective studies.
