To evaluate Mexican-American adolescents' descriptions of their weight status.
Data were from the Hispanic Health and Nutrition Examination Survey, conducted in 1982-1983 among Mexican-Americans in five southwestern states. The current study used data on 429 males and 485 non-pregnant females 12-19 years old. In an interview, participants were asked to describe their weight status (underweight, about the right weight, overweight); in an examination (performed two to four weeks after the interview), weights and heights were measured. Each participant's body-mass index (weight/height2) was calculated, and single year of age-and-sex-specific BMI cutoffs were used to determine each participant's BMI decile.
The overweight description was chosen by 46% of females and 23% of males, and the underweight description by 7% of females and 17% of males. The percentage of adolescents self-described as overweight rose with increasing BMI percentile, the rise starting in the 30-39th percentiles for females and in 60-69th percentiles for males.
These findings suggest that many Mexican-American adolescents misperceive their weight status.
评估墨西哥裔美国青少年对自身体重状况的描述。
数据来自1982 - 1983年在五个西南部州对墨西哥裔美国人进行的西班牙裔健康与营养检查调查。本研究使用了429名12 - 19岁男性和485名非孕女性的数据。在一次访谈中，参与者被要求描述他们的体重状况（体重过轻、体重合适、超重）；在一次检查中（在访谈后两到四周进行），测量体重和身高。计算每个参与者的体重指数（体重/身高²），并使用按年龄和性别划分的单一年度体重指数临界值来确定每个参与者的体重指数十分位数。
46%的女性和23%的男性选择了超重描述，7%的女性和17%的男性选择了体重过轻描述。自我描述为超重的青少年比例随着体重指数百分位数的增加而上升，女性从第30 - 39百分位数开始上升，男性从第60 - 69百分位数开始上升。
这些发现表明，许多墨西哥裔美国青少年错误地感知了他们的体重状况。
