Impact of Face Masks on Female Body Perception is Modulated by Facial Expressions

People routinely wear face masks during the pandemic, but little is known about their impact on body perception. In this online study, we presented female body images of Caucasian avatars in common dress sizes displaying happy, angry, and neutral facial expressions with and without face masks, and asked women to rate the perceived body attractiveness and body size. In comparison with mask-off condition, mask-on decreased body attractiveness ratings for happy avatars but did not affect ratings for neutral avatars irrespective of avatar dress sizes. For avatars displaying angry expressions, mask-on increased body attractiveness ratings for slimmer avatars but did not affect ratings for larger avatars. On the other hand, body size estimation was not systematically affected by face masks and facial expressions. It appears that face masks mainly show an expression-dependent influence on body attractiveness judgement, possibly through suppressing the perceived facial expressions.

Assessment of Eating Habits and Perceived Benefits of Physical Activity and Body Attractiveness among Adolescents from Northeastern Romania

The purpose of this paper was to present the results of the evaluation of 1320 adolescents from 4 high schools in Iaşi, Romania regarding their eating habits and perceived benefits of physical activity and body attractiveness after they completed an anonymous questionnaire. The data analysis was performed using IBM SPSS version 18. The analysis of the nutritional status showed that over 70% of adolescents were of a normal weight. Most of them (63.56%) consumed 3–4 meals/day, with breakfast being the most skipped meal (60.53%). Compared with the boys, the girls consumed fewer whole grains, dairy products, and meat, but the girls consumed fruits and vegetables in approximately the same percentage. The adolescents studied consumed more fruits than vegetables, but the servings of fruits and vegetables consumed were not sufficient in the diets of many adolescents (39.31%). Among the adolescents, 5.68% consumed at least 2 alcoholic drinks daily, and 37.87% consumed caffeine products one or more times per week. Among the boys, 95.20% practiced regular physical activity, and 97.20% of the girls considered that the right nutrition plays a role in the prevention of obesity. The study of the self-perception profile showed that 89.8% of boys and 79.5% of girls considered that they had attractive bodies. According to the BMI, 86.7% of normal-weight adolescents and 84.8% of underweight adolescents considered themselves as having attractive bodies, while this was only considered by 73.5% of overweight and 56.7% of obese adolescents. It is necessary to introduce nutritional education in schools for the improvement of eating habits in children and adolescents. More studies are needed to appreciate the social behaviors (e.g., food intake, physical activity, and recreation time) and then develop interventions and national health programs to promote a healthy lifestyle, particularly healthy eating habits.

MHC Class II Heterozygosity Associated With Attractiveness of Men and Women

The genes of the Major Histocompatibility Complex (MHC), which plays a fundamental role in the immune system, are some of the most diverse genes in vertebrates and have been connected to mate choice in several species, including humans. While studies suggest a positive relationship between MHC diversity and male facial attractiveness, the connection of MHC diversity to other visual traits and female attractiveness is still unclear. The purpose of this study was to investigate further whether MHC heterozygosity, indicating genetic quality, is associated with visual traits affecting mate preferences in humans. In total 74 Latvian men and 49 women were genotyped for several MHC loci and rated for facial and, in men, also body attractiveness. The results indicate a preference for MHC heterozygous female and male faces. However, the initially positive relationship between MHC heterozygosity and facial attractiveness becomes non-significant in females, when controlling for multiple testing, and in males, when age and fat content is taken into account, referring to the importance of adiposity in immune function and thus also attractiveness. Thus overall the effect of MHC heterozygosity on attractiveness seems weak. When considering separate loci, we show that the main gene related to facial attractiveness is the MHC class II DQB1; a gene important also in viral infections and autoimmune diseases. Indeed, in our study, heterozygous individuals are rated significantly more attractive than their homozygous counterparts, only in relation to gene DQB1. This study is the first to indicate a link between DQB1 and attractiveness in humans.

College Females' Self-Perceptions of Their Overall Physical Self-Worth

The purpose of this study was to determine whether significant differences exist in the domain of overall physical self-worth and the subdomains of sport competence, physical condition, body attractiveness, and physical strength between intercollegiate athletes and regular exercisers, intercollegiate athletes and nonexercisers, and regular exercisers and nonexercisers. The Physical Self-Perception Profile (PSPP) was used to survey female college students attending one Midwestern University. It was concluded that college females who engaged in sport competition and exercise participation perceived their physical selves more positively than did female nonexercisers.
