Abstract

Objectives

Self perceived body image among women is drawing a lot of attention in Korea due to their unhealthy weight control behaviors. To determine the relationship between self-perceived body image and dietary behaviors among Korean women, the discrepancy between actual body size and body image perception, weight control behaviors were assessed based on age groups using the 2010 KNHANES data.

Methods

A total of 1,747 subjects were selected after eliminating those of likely changing their diet recently using the 2010 KNHANES data. The subjects were divided into 3 groups, self-underweight, self-normal, and self-obese according to their perception of body image. The BMI and weight control behaviors were assessed based on age groups according to the body image perception.

Results

The younger, the higher ratio of underweight, women perceived their body size as normal or overweight. Exercise and reduced food intakes were dominant among various weight control methods but unhealthy methods were dominant among self perceived overweight group.

Conclusions

Incorrect body image perception and unhealthy weight control behaviors can cause nutritional problems. Nutritional education should emphasize the importance of healthy weight and proper body image perception for Korean women.

Keywords: self-perceived body image, weight control behavior, Korean women

Parameters of general linear model of body image perception and BMI on age

1) BP=Body image perception, BP=1 (under weight), BP=2 (normal), BP=3 (obesity), Subpopulation: (Sex=Female & age >=12)

2) Set to zero because this parameter is redundant.

Model: BMI=(Intercept)+Body image perception+age. ***: P < 0.001
