Abstract
Abstract Aim To study whether fitness level in adolescence predicts body image in young adulthood. Methods Longitudinal study in which n = 385 participants were measured at age 15 and n = 201 at age 23. Fitness was assessed both objectively and subjectively. Body image was evaluated with the Offer Self- Image Questionnaire. Cross-lagged structural equation model was used to study whether fitness at age 15 predicted body image at age 23, covariates included sex, body mass index, physical activity, and socioeconomic status. Results Aerobic fitness at age 15 was the strongest predictor (β = 0.372; p  Conclusion Objectively measured fitness in adolescence is an independent predictor of body image in young adulthood, whereas self-reported fitness is not. Strong fitness in adolescence is important for a healthy body image later in life.

This study examines the long-term development of different domains of body esteem (BE), the most salient domain of adolescents' global self-esteem. The 11-year longitudinal study of Swedish youths, covering ages 10–21, showed that BE undergoes significant change from late childhood to young adulthood, with growth curve models revealing different developmental paths between domains and across gender. For girls, general appearance esteem and weight esteem decreased in the early adolescent phase an...

In 11 680 individuals (18–85 years) maximal oxygen consumption (VO 2 max) was estimated indirectly in a maximal cycle test using a prediction model developed in a young population (15–28 years). A subsample of 182 individuals (23–77 years) underwent 2 maximal cycle tests with VO 2 max estimated indirectly in both tests and measured directly in one test. Agreement between the direct measurement and the indirect estimate of VO 2 max and repeatability of the indirect estimates of VO 2 max were exam...

Abstract Individuals with a positive body image appreciate their bodies, hold an internal perspective of their bodies, and are satisfied with the functionality of their bodies. Research shows that positive body image is more complex than the absence of body dissatisfaction. Although exercise reduces women's body dissatisfaction, very little research has explored how, or even whether, exercise is associated with positive body image. Therefore, we examined whether exercise frequency was positively...

Summary What is already known about this subject Eating disorders are among the public health issues facing adolescents. An excess of body fat has been associated with an increased risk of these disorders. The association of physical fitness with eating disorders has not yet been analysed in adolescents. What this study adds This study confirms that the overweight and obesity increase the risk of developing eating disorders. The present study shows that there is an inverse association between ph...

The aim of this study was to investigate if physical fitness (strength/power, endur ance, flexibility and coordination) mediates the cross-sectional relationship between physical activity and physical self-perception (athletic competence and physical appearance) in a sample of 15-year old adolescents. We wanted to investigate the relative strength of each indirect effect. The present data are taken from two waves of a larger data collection for the project “Youth in Balance”, and was collected i...

Adolescents with unusually sized or shaped bodies may experience ridicule, rejection, or exclusion based on their negatively valued bodily characteristics. Such experiences can have negative consequences for a person’s image and evaluation of self. This study focuses on the relationship between bodily deviations and body image and is based on a national survey of 3,898 students attending 9th and 10th grade (age 14-16) in the Icelandic school system (92% response rate). Girls had a considerably l...

Abstract The aim of this study was to evaluate trends in body image among Icelandic adolescents from 1997 to 2010. Data from five cross-sectional surveys conducted among national samples of 9th and 10th graders in Iceland using five time points (1997, 2000, 2006, 2009, and 2010) were compared to examine changes in body image. In total, 32,397 adolescents participated in the study. Body image among 14–15-year-old adolescents in Iceland improved significantly over the 13-year period. Girls reporte...

Background: A relevant, but overlooked question is if self-reported physical activity and aerobic fitness are differently related to mental health. Purpose: To examine the relation between mental health and level of self-reported physical activity (SRPA) and aerobic fitness (AF), and whether AF mediates the relation between SRPA and mental health. Methods: Participating in the study were 177 voluntary subjects (49% men, 51% women) with a mean age of 39 years. Symptoms of depression and anxiety w...

Adolescence is a life phase in which the opportunities for health are great and future patterns of adult health are established. Health in adolescence is the result of interactions between prenatal and early childhood development and the specifi c biological and social-role changes that accompany puberty, shaped by social determinants and risk and protective factors that aff ect the uptake of health-related behaviours. The shape of adolescence is rapidly changing— the age of onset of puberty is ...

Abstract Objectives Sleep duration and physical activity decline with age during adolescence. Earlier school schedules may contribute to these declines. The aim of this longitudinal study was to track changes in sleep and activity of Icelandic youth from primary to secondary school and compare students who enrolled in secondary schools with traditional and college-style schedules. Methods We measured free-living sleep and activity with wrist actigraphy and body composition by dual-energy x-ray a...

Body Dissatisfaction (BD) and low physical self-concept and exercise efficacy have been linked to poor physical fitness levels and adverse health outcomes in children. The purpose of this study was to examine the relationship between BD, physical fitness, exercise self-efficacy, and self-Perception of Physical Fitness (PFP) in Latina and Black female children. Twenty-eight Latina and Black children enrolled in an elementary afterschool program, aged 8–12, completed surveys evaluating body dissat...
