Satisfaction with overweight and obesity purportedly contribute to greater weight gain in African American women than men, yet relatively little data on perceived (PBI) and ideal body image (IBI) are available for young adult African Americans. In this survey, 509 self-identified African American freshmen in 2003 and 669 in 2006 at a historically Black university completed a survey that included self-reported height, weight and IBI. In 2003 and 2006, 42.2%-48.8% of men and women were overweight (body mass index [BMI] 25.0-29.9 kg/m2) or obese (BMI > or = 30). In both surveys, >75% of overweight women and >90% obese women selected a smaller IBI. In contrast, a greater proportion of overweight men was satisfied (approximately 50%) than the proportion who had larger than IBI (<40%). Among students with a normal BMI (<25), men were more likely than women to report being smaller than ideal (>45% vs <26%). However, overweight women were more likely than overweight men to select a normal PBI (48.5% vs 36.0%). The data in African American college freshman do not suggest that greater weight gain in women than men is driven by a desire to be heavier. The high proportion of overweight women with a normal PBI may contribute to greater weight gain. Of concern, nearly half of men with normal BMI want to be heavier, while approximately 5/8 of overweight men are satisfied with being overweight or want to be heavier.
据称,非裔美国女性对超重和肥胖的满意度导致她们比男性体重增加更多,但关于年轻成年非裔美国人的感知身体形象(PBI)和理想身体形象(IBI)的数据相对较少。在这项调查中,一所历史悠久的黑人大学2003年的509名自我认定的非裔美国新生和2006年的669名新生完成了一项调查,其中包括自我报告的身高、体重和IBI。在2003年和2006年,42.2%-48.8%的男性和女性超重(身体质量指数[BMI]25.0-29.9kg/m²)或肥胖(BMI≥30)。在两项调查中,超过75%的超重女性和超过90%的肥胖女性选择了较小的IBI。相比之下,超重男性中满意的比例(约50%)高于选择大于IBI的比例(<40%)。在BMI正常(<25)的学生中,男性比女性更有可能报告自己比理想体重小(>45%对<26%)。然而,超重女性比超重男性更有可能选择正常的PBI(48.5%对36.0%)。非裔美国大学新生的数据并不表明女性比男性体重增加更多是由渴望更胖所驱动的。具有正常PBI的超重女性比例较高可能导致体重增加更多。令人担忧的是,近一半BMI正常的男性希望体重更重,而大约八分之五的超重男性对超重感到满意或希望体重更重。
