一些报告表明，在生活在高度发达国家的各种社会群体中，与根据估计的实际体重和身高计算的体重指数（BMI）相比，体重感知和体重满意度往往是不适当的。因此，在目前的研究中，在波兰的药学专业学生的样本人群中，体重感知，测量的实际BMI，性别和节食习惯之间的关系进行了检查，以验证假设，他们不正确的自我认知会引起偶尔的，季节性的和永久性的饮食失调。收集了波兰Bydgoszcz的178名药学专业学生（平均年龄22.6 ± 2.4岁）的身高和体重数据，并通过完成的自我报告问卷进行了验证，该问卷评估了他们的自我感知体重、期望体重和过去/当前的节食实践。只有34.4%的女生和37.1%的男生对自己目前的体重感到满意。统计分析显示，不同性别的BMI估计值（chi（2）= 28.5; p = 0.0001）、期望体重（chi（2）= 15.6; p = 0.0004）和既往节食情况（chi（2）= 7.6; p = 0.0050）存在显著差异。在男性学生亚组（n = 27）中，测量的实际BMI状态和自我感知的体重之间的关联不明确（卡方（2）= 6.1; p = 0.046）。此外，在男生中，实际BMI状态与过去和当前节食形式的体重控制行为之间存在显著关系（chi（2）= 4.9; p = 0.0261）。在一个小组的女学生（它= 15 - 1）的情况下，实际的BMI和自我感知的体重（卡方（2）= 69.5，p = 0.0001）的扩散关联。然而，在女性中观察到实际BMI和仅过去节食实践之间的密切关系（chi（2）= 16.9; p = 0.0007）。此外，在最后一个学生亚组中，还证明了测量的实际BMI和期望体重之间的显著关系（chi（2）= 53.9; p = 0.0001）。这项研究表明，在两个分组的考虑药学专业的学生扭曲的自我认知的体重的证据。女生有高估体重的倾向，男生有低估体重的倾向。这些结果表明，对体重普遍不满，尤其是女性，她们更经常节食，尽管根据测量的实际BMI状态并不超重或肥胖。(C)2008年，Elsevier Masson SAS。All rights reserved.
Some reports indicate that in various groups of society living in the highly developed countries a body weight perception and weight satisfaction tend to be inappropriate when compared with body mass index (BMI) calculated from estimated actual weight and height. Thus in present studies a relationship between body weight perceptions, measured actual BMI, gender, and dieting practices in a sample population of pharmacy students in Poland were examined to verify hypothesis that their incorrect self-perception would provoke occasional, seasonal and permanent eating disorders. Height and weight data of 178 pharmacy students (mean age 22.6 +/- 2.4 years) in Bydgoszcz, Poland, were collected and validated by completed self-reported questionnaire assessing their self-perceived body weight, desired body weight and past/current dieting practices. Only 34.4% of female and 37.1% of male pharmacy students was satisfied with their current body weight. Statistical analyses revealed significant differences in estimated BMI status (chi(2) = 28.5; p = 0.0001), desired body weight (chi(2) = 15.6; p = 0.0004) and past dieting (chi(2) = 7.6; p = 0.0050) by gender. In the male sub-group of students (n = 27) unclear association (chi(2) = 6.1; p = 0.046) between measured actual BMI status and self-perceived body weight have been presented. Moreover, in male students a significant relationship (chi(2) = 4.9; p = 0.0261) between actual BMI status and both past as well as current weight control behavior in the form of dieting practices was exhibited. In case of a sub-group of female students (it = 15 1) a diffuse association of actual BMI and self-perception of their body weight (chi(2) = 69.5; p = 0.0001) was obtained. However, a close relation (chi(2) = 16.9; p = 0.0007) between actual BMI and only past dieting practices was observed in females. Furthermore, in this last sub-group of students the significant relationship (chi(2) = 53.9; p = 0.0001) between measured actual BMI and desired body weight was also demonstrated. The study showed an evidence of distorted self-perception of body weight in both sub-groups of considered pharmacy students. There was a tendency to overestimate of body weight in female students, and to underestimate in male students. These results suggest common dissatisfaction of body weight, especially among females, who were more often engaged in dieting, despite not being overweight or obese according to measured actual BMI status.
