Demographic differences in and correlates of perceived body image discrepancy among urban adolescent girls: a cross-sectional study

Beliefs and Perceptions of Physical Activity Among Black Adolescents in South Florida: A Qualitative Study

INTRODUCTION

In the United States, non-Hispanic Black adolescents have a significantly higher prevalence of obesity than their peers. Though physical activity (PA) has many benefits, many adolescents fail to engage in adequate amounts of PA. Black adolescents are also more sedentary than those from other races and ethnicities. This study aimed to describe the perceptions, beliefs, and barriers to PA in South Florida Black adolescents.

METHODS

Five focus groups were conducted with self-identified non-Hispanic Black adolescents (n = 38) in South Florida. A semi-structured question guide based on the Theory of Planned Behavior was used for group discussions. The open-ended questions addressed adolescents' (1) attitudes and beliefs toward PA, (2) current PA-related behaviors, and (3) environmental, social, cultural, and racial influences on health behaviors.

RESULTS

The desire to be healthy, thoughts of the future, and self-image were among the reasons participants engaged in PA. Engagement in PA was associated with a positive social environment, including encouragement from family and friends. Race, culture, and social media were also cited as influences on PA. Perceived control beliefs, such as parental pressures and self-discipline, also impacted PA.

CONCLUSION

Adolescents recognize the importance of PA; however, their behaviors do not reflect this. Barriers and motivators for Black adolescents are multifaceted. It is critical for Public Health practitioners and local legislators to understand the complexities to serve this population. This study's findings can guide the development of tailored PA and education programs for Black adolescent populations.

Weight misperception and weight-related behaviors in non-Hispanic Black youth

Current literature is conflicting regarding whether accurate weight perception encourages healthy weight-related behaviors. This study examined the prevalence of weight misperception and explored associations between weight misperception and weight-related behaviors among 353 Black adolescents in Broward County, Florida. Overall, 44.8% of participants misperceived their weight, with boys more often misperceiving their weight than girls (52.2% vs 40.2%). Students who misperceived their weight were more likely to try to lose weight but less likely to be adequately physically active. Adolescents who underestimated their weight were less likely to be physically active and excessively play video or computer games or use a computer. There was no association between weight misperception and daily physical education attendance or excessive television watching. Weight misperception appears to be a risk factor for obesity in adolescents, as weight misperception was associated with lower engagement in physical activity.

Physical Activity and Body Image Perception in Adolescents: A Systematic Review

Adolescence represents a vulnerable phase of life for psychological health. The practice of physical activity (PA) appears to have a positive influence on adolescents, increasing self-esteem and producing a more positive body image. A systematic review of published articles over the past 10 years until June 2022 was conducted according to the PRISMA statement employing the electronic databases MEDLINE and Web of Science (639 records) to summarize the literature on the relationship between body image dissatisfaction (BID) and assessed by figural scales and practice of structured and unstructured PA in adolescents (10-18 years), taking into account BMI and/or weight status. All articles were independently reviewed using inclusion/exclusion criteria, retrieved data, and assessed quality with the adapted Newcastle-Ottawa Scale for observational studies. The main finding of interest that emerged from most of the 28 included studies is the negative association between BID and PA during adolescence: as PA increases, BID decreases. However, this updated systematic review also identified some flaws in the existing literature, highlighting the need for high-quality adolescent research using validated figural scales and objective PA assessments. In conclusion, the reviewed studies showed that PA involvement can be efficacious in protecting from body image perception concerns and enhancing body satisfaction. Future interventions should promote structured and unstructured PA during adolescence to improve self-esteem and body image.

Psychometric investigation of the Attention to Body Shape Scale in Brazilian adults

The objectives of the study were to develop a Portuguese version of Attention to Body Shape Scale (ABS), estimate the psychometric properties of the ABS for Brazilian data, and compare the ABS scores between the sexes and the different sample characteristics. The Portuguese version was developed following a standardized protocol. The factorial and convergent validity were evaluated using goodness-of-fit parameters and average variance extracted. Composite reliability and ordinal coefficient alpha were calculated. The invariance of the fitted model was investigated across independent subsamples using multigroup analysis. The scores were compared between variables using two-way ANOVA. A total of 1,056 individuals (71% female) with a mean age of 26.1 (SD=6.4) years participated in the study. Item 3 was removed due to low factor loading. The refined model presented good psychometric properties for the data. Different characteristics contributed to greater attention to body shape. The Portuguese version of the ABS will be useful to investigate attention to body shape in Brazil. The validity and reliability of the data supported the adequacy of the refined model. Specific characteristics influenced attention to body shape, and therefore, should be considered in future protocols.

Composition and Factorial Invariance for the Assessment of Body Image Dissatisfaction Questionnaire in Mexican Adolescents

Body image is a mental representation that a person has, which could become a body dissatisfaction due to the pressure exerted by the culture, affecting several life stages specially in adolescents. The aim of this study was to analyze the psychometric properties and factorial invariance of the questionnaire to assess body image dissatisfaction. The sample consisted of 552 Mexican teenagers, 259 female, and 293 male, with a mean age of 12.91 ± 0.96 years. Confirmatory Factor Analyses show that a five-factor structure is viable and adequate. The five-factor structure (perceptual, emotional distress, behavioral, proposal to change, and fear of gaining weight) show adequate fit indices and validity, even though the obtained model does not completely correspond to that proposed by the authors of the scale, it continues to endorse the multifactorial component of body dissatisfaction. On the other hand, the factorial structure, the factor loadings, and the intercepts are considered invariant in both populations; however, there are differences between the populations for the means of the perceptual, emotional distress, and fear of gaining weight factors. This study serves as a premise for future research on the study of instruments for measuring body image in populations with different personal and cultural factors.

Healthier Minds in Fitter Bodies: A Systematic Review and Meta-Analysis of the Association between Physical Fitness and Mental Health in Youth

BACKGROUND

Physical fitness is an important marker of current and future health status, yet the association between physical fitness and indicators of mental health in youth has not been systematically reviewed and meta-analyzed.

OBJECTIVE

The aim of this work was to systematically review and meta-analyze the association between physical fitness components (i.e. cardiorespiratory fitness, muscular fitness, speed-agility, flexibility and fitness composite) and mental health indicators (i.e. psychological well-being and psychological ill-being) in preschoolers, children and adolescents.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Systematic searches were conducted in PubMed, Web of Science and Scopus from database inception to May 2020.

ELIGIBILITY CRITERIA

Studies (cross-sectional, longitudinal and intervention designs) were included if they measured at least one physical fitness component and one mental health indicator in healthy youth (2-18 years).

RESULTS

A total of 58 unique studies (52 cross-sectional, 4 longitudinal and 4 intervention studies) met all eligibility criteria and were included. There was a significant positive overall association between physical fitness and mental health in children and adolescents (pooled r = 0.206, p < 0.001). We found suggestive evidence of moderation by age group, fitness components and socioeconomic status (all p < 0.08). No relevant studies focusing on preschoolers were identified. Evidence based on longitudinal and intervention studies was limited.

CONCLUSION

We observed a small to medium sized positive association between physical fitness and overall mental health in youth. However, as the majority of studies were cross-sectional, additional longitudinal and intervention studies are needed to provide evidence of causation.

Self-Perceptions, Normative Beliefs, and Substance Use Associated With High School Girls Comparing Themselves to Peers

BACKGROUND

We assessed whether self-descriptions, self-perceptions, perceived substance use of friends, and actual substance use were associated with high school girls' frequency of making social comparisons to peers.

METHODS

We analyzed data from the Adolescent Health Risk Behavior Survey data for 357 high school girls using multinomial logistic regression.

RESULTS

Compared to those who "never/rarely" made social comparisons, participants who self-described as fearing something constantly (p = .014) and forced to imitate the people they like (p = .009) were more likely to "usually" compare themselves to peers. Participants who described themselves as feeling forced to imitate the people they like (p = .022), were not the person they would like to be (p = .005), and did not remain calm under pressure (p = .010), were more likely to "often/always" make social comparisons. Participants who perceived themselves as unattractive (p = .034) and self-centered (p = .016) were more likely to "often/always" make social comparisons. Participants who perceived a larger proportion of friends use illicit drugs were less likely to "usually" make social comparisons (p = .027). Participants who perceived a larger proportion of friends drink alcohol were more likely to "often/always" make social comparisons (p = .018).

CONCLUSIONS

Girls who perceive and describe themselves more negatively are at increased odds of making social comparisons to peers.

Physical Activity, Physical Fitness and the Sense of Coherence-Their Role in Body Acceptance among Polish Adolescents

The aim of the study was to investigate the protective role of physical activity (PA) and other health-related bio-psycho components (physical fitness, body composition, body perception and the sense of coherence (SOC)) in body acceptance. We searched for gender differences in those relationships. We investigated 231 adolescents aged 13-16 years from an urban area in Poland. We conducted objective measurements of height, weight, fat% and relative value of minute oxygen consumption. Questionnaires for PA, SOC Body Figure Perception and body acceptance were applied. Linear regression was used for analyzing determinants of body acceptance. We found that more physically active girls reported a less slim ideal vision of their figure (p < 0.05). Physical fitness is a better predictor of body acceptance than physical activity. In the final model, the sense of coherence, body mass index (BMI), and gender (being a boy) were also predictors of body acceptance (F(6,92) = 13.084, p < 0.0001). Gender differences were discussed in the present study. Fitness enhancing physical activity should be recommended for adolescents to achieve the protective psychosocial effect especially among girls. Physical activity on a daily basis brings positive results in a more adequate and reasonable body assessment and it can play a protective role in terms of mental wellbeing. Body satisfaction varies between genders and it is a more sensitive issue among girls than boys during adolescence.

Association of Health Status and Health Behaviors with Weight Satisfaction vs. Body Image Concern: Analysis of 5888 Undergraduates in Egypt, Palestine, and Finland

Little is known about the relationships between weight satisfaction, body image concern, healthy nutrition, health awareness, and physical activity among college students across culturally different countries. We assessed country and sex-specific associations between health status (self-rated health, depression, BMI), healthy behavior (healthy nutrition, physical activity, health awareness), weight satisfaction, and body image concern via a cross-sectional survey (5888 undergraduates) in Egypt, Palestine, and Finland. This health and wellbeing survey employed identical self-administered paper questionnaires administered at several Universities in two Eastern Mediterranean countries (Egypt, Palestine—Gaza Strip), and an online-survey comprising the same questions in Finland. Regression analyses were employed. Health status variables exhibited the strongest associations; high BMI and more depressive symptoms were more often among students satisfied with their weight (except in Palestine), but they were positively associated with body image concern irrespective of country or gender. Self-rated health was not associated with body image concern or weight satisfaction. Healthy behaviors were not associated with body image concern or weight satisfaction. Depressive symptoms and BMI were the most prominent predictors for body image concern. There were country-specific consistent results when using the body image concern score. Further research is necessary to compare body image across different cultures and countries.
