Body image perception, smoking, alcohol use, indoor tanning, and disordered eating in young and middle-aged adults: findings from a large population-based Swedish study

Background Body image concerns may give rise to a multitude of risk behaviors, such as unhealthy weight control practices, disordered eating behaviors (e.g., compensatory purging or preoccupation with food), smoking, excessive alcohol intake, or sunbed use. However, the distribution of these risk behaviors across adulthood has rarely been studied. Methods The aim of this study was to explore health risk behaviors as correlates of body image perception in a randomly selected study population of 30,245 individuals aged 30–66 in Stockholm, Sweden, utilizing data from the Stockholm Public Health Cohort. Bivariate correlations were explored and a hierarchic binary logistic regression analysis was performed. Results The prevalence of body image discrepancy was higher among smokers and respondents displaying disordered eating behaviors. In contrast, alcohol and sunbed use were inversely correlated to body image discrepancy. Body mass index was the substantially strongest explanatory factor behind the observed variance in body image discrepancy, followed by loss-of-control eating. Notably, no major gender differences in body image perception were detected. Some unexpected patterns of association between variables other than body image perception, such as those between smoking, alcohol use, and sunbed use, were seen. Conclusions Overall, the patterns differ substantially from what has previously been found in adolescent and young adult samples, indicating that the synergy and aggregation of risk behaviors observed among younger individuals may not apply to adults aged 30–66.

Differential Child Body Perception in Children Ages 7–12 and Parents in Relation to Exercise and Eating Behaviors

Objectives Individuals with distorted perceptions of body image may be at an increased risk of developing eating disorders and mental illnesses. Many studies have observed impaired body image perceptions in adolescents and adults over the age of twelve. However, there are few studies that have examined this in young children. Furthermore, few studies that examine body image differences between parents and children exist. The purpose of this study was to investigate differential child body perceptions in children ages 7–12 and parents in relation to exercise and eating behaviors. Methods In a cross-sectional study, two separate questionnaires were designed; one for parents (n = 145) and the other for their paired children (n = 145). Questionnaires included anthropometric, exercise and eating behavior, and somatotype questions to assess perceived current and perceived ideal body type. Results Child responses of child's current body type were significantly greater than parent responses of child's current body type (P = 0.022). Child responses of child's ideal body type were significantly lesser than parent responses of child's ideal body type (P = 0.001). Child-reported child body type discrepancy (current body type – ideal body type) was significantly greater (0.414 ± 0.902) than parent-reported child body type discrepancy (−0.014 ± 0.717) (P = 0.001). There was a significant positive correlation between body image discrepancy and reports of faster eating pace (coefficient = 0.237, P = 0.004) and a significant negative correlation between body image discrepancy and family physical activity (coefficient = –0.183, P = 0.017). Conclusions Significant discrepancies between perceived current and ideal body type were observed in children ages 7–12. Faster eating pace and family physical activity may be contributing factors to body type discrepancy among children ages 7–12, though more research is needed to identify and examine other potential factors such as social media usage and perceptions of physical activity. This research indicates a need for increased education aimed at forming and maintaining healthy body image perceptions among young children ages 7–12. Funding Sources None.

The effect of virtual avatar experience on body image discrepancy, body satisfaction and weight regulation intention

This experimental study aimed to investigate the effect of having a virtual avatar experience on health outcomes in the context of body image and weight regulation. Ninety-three U.S. non-clinical participants (51 men and 42 women) were recruited, who were 18 years and older and had no history of chronic health problems or mental illnesses. Each experiment consisted of the three data collection phases, including the pre-experiment survey, an experience session of a virtual self-avatar, and the post-experiment survey. For the development of the virtual avatar protocol, this study employed 3D body scanning to create a participant’s virtual body model based on accurate anthropometric data, to simulate a virtual avatar closely matched with the participant’s actual physique. Overall, the data indicated an increase in perceived body image discrepancy and a decrease in body satisfaction after participating in a virtual avatar session, and those who showed higher body dissatisfaction exhibited a stronger intention regulated for weight control. Specifically in gender, the statistical results were generally intensified in the female group, but the male group showed a stronger intention to be involved in exercising after virtual avatar experience. The insights gained from this study suggested future directions for research and program development, and urged that practical applications of the virtual avatar approach must be implemented with caution when it uses clinical samples, because its risk-benefit assessment has not been sufficiently investigated yet.

Body Image Discrepancy and Body Mass Index among Chinese University Students in Hong Kong

LANGUAGE NOTE | Document text in English; abstract also in Chinese. Introduction: The purposes of this study were to examine (a) the relationship between Body Mass Index (BMI) and the perception of body image, (b) the body satisfaction level (BSS), and (c) the most satisfied and dissatisfied body part. Methods: 588 university students (aged: 20.0±2.2 years; BMI: 20.3±2.8 kg/m2) from four universities in Hong Kong indicated their perceived ‘ideal’ and the ‘healthiest’ male and female figure from 9-figure rating scale. Body Image Discrepancy (BID) between their ‘current’ and ‘ideal’ figure was calculated. Results: Men reported significantly higher level of BSS than women. BMI correlated with BSS in women (r=.-263, p<.01) but not in men; BMI correlated with BID in women (r=.446, p<.001) and men (r=.587, p<.001). Most respondents indicated ‘no part’ as their most satisfied body part. Men and women stated their most dissatisfied body part was abdomen and thigh respectively. BSS was the highest in normal weight men and underweight women. Overweight respondents rated significantly larger figure as their ‘ideal’ size than their underweight and normal weight counterparts. Conclusions: An increase in BMI aggravates an increase in their desire to be thinner. It is necessary to help university students in Hong Kong to develop a healthy and realistic body image. 探討大學生(1)身體質量指數(BMI)與身體形象差異的關係; (2)身體滿意度; (3)最滿意和最不滿意自己身體部份。588位大學生從香港四所大學在9個由瘦至肥的男女剪影公仔中選擇(1)“理想”和“最健康”的男女體型; (2)代表自己“現在”和“理想”的體型來計算出身體形象差異。女性的身體滿意度比男性低並與BMI成反比。大多數指無最滿意的身體部份，男女分別最不滿意腹部和大腿。正常體重男士和過輕女士最滿意自己身體。總結，BMI與減磅意欲成正比。
