1995 study, black men were more likely than white men to use the words "big" or "large" to describe their conception of an attractive woman's posterior. Body mass Body Mass Index (BMI) is an important determinant to the perception of beauty. Even though the Western ideal is for a thin woman, some cultures prefer plumper women, which has been argued to support that attraction for a particular BMI merely is a cultural artifact. The attraction for a proportionate body also influences an appeal for erect posture. One cross-cultural survey comparing body-mass preferences among 300 of the most thoroughly studied cultures in the world showed that 81% of cultures preferred a female body size that in English would be described as "plump". Availability of food influences which female body size is attractive which may have evolutionary reasons. Societies with food scarcities prefer larger female body size than societies that have plenty of food. In Western society males who are hungry prefer a larger female body size than they do when not hungry. BMI has been criticised for conflating fat and muscle, and more recent studies have concentrated on body composition. Among Australian university students, the most attractive body composition for women (10.31 kg fat, 42.45 kg muscle) was found to be lower in fat than both the most healthy appearing composition, and below the healthy range. In the United States, women overestimate men's preferences for thinness in a mate. In one study, American women were asked to choose what their ideal build was and what they thought the build most attractive to men was. Women chose slimmer than average figures for both choices. When American men were independently asked to choose the female build most attractive to them, the men chose figures of average build. This indicates that women may be misled as to how thin men prefer women to be. Some speculate that thinness as a beauty standard is one way in which women judge each other and that thinness is viewed as prestigious for within-gender evaluations of other women. A reporter surmised that thinness is prized among women as a "sign of independence, strength and achievement." Some implicated the fashion industry for the promulgation of the notion of thinness as attractive. East Asians have historically preferred women whose bodies had small features. For example, during the Spring and Autumn period of Chinese history, women in Chinese harems wanted to
