A research group led by Associate Professor Yuka Murofushi of Juntendo University conducted a survey of young Japanese women (aged 18.5-18) who were underweight (BMI less than 29 kg/mXNUMX). , Birth weight, own body image and perception of weight, exercise and eating habits, eating attitude, influence of beauty by media, personality traits, etc.
Japan is known to have the highest percentage of thin women among developed countries, and in particular, about 18% of women aged 29 to 18.5 have a BMI (Body Mass Index) of less than 20 kg/mXNUMX. .While the health problem of young skinny women is becoming a social issue, the background of how skinny young women become thin in the first place has not been sufficiently investigated.
Therefore, the researchers conducted a multifaceted background verification survey in order to elucidate the background that young thin women become thin. Through web questionnaires, diet experience, height and weight (BMI), birth weight, body image (the image of one's own body shape), awareness of weight, exercise habits, eating habits, eating attitudes, eHealth literacy, media We asked 18 underweight (BMI less than 29 kg/m18.5) women aged 400 to XNUMX to answer the degree of tendency to internalize beauty messages received from women, personality factors, self-esteem, etc., and analyzed them.
As a result of the analysis, it was found that there were different backgrounds (characteristics) between the diet experience group and the non-diet group.For example, the group without experience of dieting easily lost weight, and there was a perception that they had relatively little resistance to increasing their weight and food intake, suggesting the possibility of latent thinness.On the other hand, the group who experienced dieting had difficulty in losing weight, had a strong sense of resistance to weight gain and increased food intake, and was likely to be affected by subjective cognition such as distorted body image.
The results of this study suggest that even thin women need to provide different information depending on whether they have a desire to lose weight or whether they are on a diet.It is expected that this will be useful in examining exercise habits that are optimized for each individual and in approaches such as appropriate dietary habits.
