School physical activity interventions: do not forget about obesity bias

Association of Basic Psychological Need Fulfillment and School Happiness with Obesity Levels and Intensity of Physical Activity during Physical Education Classes in South Korean Adolescents

This study examined the relationship between basic psychological need fulfillment (BPNF) and school happiness in relation to the intensity of physical activity exhibited by adolescents during physical education (PE) classes and their obesity levels. We measured BPNF and school happiness using a questionnaire administered to 600 junior high school students. After exclusion, 532 questionnaires were analyzed. A 3D accelerometer (GT3X model) from Actigraph and the body mass index were used to measure physical activity intensity and obesity, respectively. The findings of this study indicate that BPNF and school happiness were significantly associated with physical activity intensity. Specifically, students who engaged in high-intensity physical activity exhibited higher levels of BPNF and school happiness. Additionally, BPNF and school happiness were not significantly related to obesity, whereas a significant relationship was observed between BPNF, school happiness, and the interaction between physical activity intensity and obesity level. This finding implies that adolescents with higher physical activity intensity and lower obesity reported higher levels of BPNF and school happiness. These findings suggest that physical activity intensity during PE classes significantly influences emotional development. Therefore, incorporating moderate-to-vigorous physical activity into PE may serve as a strategy for promoting emotional development in adolescents.

Use of Focus Groups to Inform a New Community-Based Youth Diabetes Prevention Program

There have been few youth-led diabetes prevention programs. Our objective was to conduct focus groups to explore peer influences on adolescent lifestyle behaviors and strategies for implementing a youth peer education model for diabetes prevention. We conducted six focus groups with 52 youth (ages 13-22; 62% male, 38% female; 64% Hispanic, 36% non-Hispanic Black) from East Harlem, NYC. We used a Thematic Analysis approach to identify major themes, compared findings, and resolved differences through discussion and consensus. Three dominant themes arose: (1) Adolescents generally encounter more unhealthy peer influences on diet and more healthy peer influences on physical activity; (2) Adolescents endorse youth-led diabetes prevention strategies and describe ideal qualities for peer leaders and methods to support and evaluate leaders; (3) Adolescents prefer text messaging to monitor behaviors, track goals, and receive personalized guidance. Using study findings, our Community Action Board developed a peer-led diabetes prevention program for prediabetic adolescents.

Predictors of Weight Bias in Exercise Science Students and Fitness Professionals: A Scoping Review

BACKGROUND

Although previous studies have reported weight bias among students and professionals in exercise science, physical education, kinesiology, and fitness instruction, predictors of weight bias in these professions have not been extensively reviewed.

AIM

The purpose of this scoping review was to explore the available literature on predictors of weight bias in exercise science students and fitness professionals to identify key concepts and research gaps.

METHODS

PubMed and ERIC were searched from January 1990 to May 2019. Eighteen studies were included in this review. A thematic analysis was conducted. Findings. Six main themes were drawn from these studies including beliefs in the personal controllability of weight; sex differences; enrollment in a health sciences-related program; psychosocial and personal factors; knowledge of obesity; lack of personal history, family, or friend with obesity. Our scoping review highlighted diverse predictors of weight bias among exercise science students and professionals that warrant further study and intervention.

Teachers' Perspectives on Creating an Inclusive Climate in Middle School Physical Education for Overweight Students

BACKGROUND

Establishing and maintaining a positive, inclusive social climate in school is essential, especially given the many potential social pressures that make school a toxic environment for vulnerable students. We explored middle school physical education (PE) teachers' perceptions of the factors that influence the implementation of social-oriented approaches to include overweight and obese students.

METHODS

We used a qualitative multicase study design guided by the Social Ecological Constraints model to study 9 PE teachers' perspectives and actions. We analyzed the transcripts of semistructured interviews, field notes, and artifacts related to teaching, PE programs, and school policies. Trust was established in conventional ways.

RESULTS

Social-ecological factors influenced teachers including program and school culture, policies, and norms of collaboration. Teachers acted beyond their instructional setting level strategies and used school-program level strategies to socially include overweight and obese in PE.

CONCLUSIONS

Some environments challenge employment of more than simple accommodations and a caring attitude; in others, teachers can collaborate with other school personnel to teach social goals through negotiating constraints, creating ingenious modifications and interactive tasks, and incorporating personal and social skills as a primary curricular goal.

Exploring Women’s Experiences: Embodied Pathways and Influences for Exercise Participation

It has been well-documented that women face pressures to conform to a slim, toned, and athletic body, becoming “tyrannised” by beauty ideals. Under these contemporary ideologies of perfectionism, women are placed under constant surveillance, evaluation and, objectification and are thus reduced to “being” their bodies. However, there is little known about the potential relationships between different types of exercise, body image, and exercise motivation. With this in mind, this paper contributes towards a small but developing body of research that utilises feminist phenomenology to reveal twelve women’s early embodied motivations for exercising and draws upon material gathered from a three-year ethnography into the embodied experiences of women in fitness cultures. This paper delves into the influences on their continued participation over time and explores how these experiences shape their understandings of the embodied self and the broader constructions of the gendered body. The discussion provided illuminates how early influences on exercise participation and how pressures on women to conform to dominant notions of the “feminine” body are imposed by structural, cultural, historical, and localised forces in ways that affect and shape future physical activity participation, and the physical cultures where these tensions are played out.

Demographic, cognitive, affective, and behavioral variables associated with overweight and obesity in low-active girls

This study examined personal, cognitive, affective, and behavioral variables related to body mass index (BMI) among 73 6th and 7th grade girls, and differences between categories of healthy weight, overweight, and obese in the variables. BMI was correlated with barriers to physical activity, enjoyment of physical activity, light physical activity, moderate to vigorous physical activity, vigorous physical activity, and sedentary time. As compared to obese girls, those who were non-obese perceived greater enjoyment of physical activity, engaged in more light and vigorous physical activity, and had fewer minutes/hour of sedentary time. Findings can inform interventions.

Public health campaigns and obesity - a critique

BACKGROUND

Controlling obesity has become one of the highest priorities for public health practitioners in developed countries. In the absence of safe, effective and widely accessible high-risk approaches (e.g. drugs and surgery) attention has focussed on community-based approaches and social marketing campaigns as the most appropriate form of intervention. However there is limited evidence in support of substantial effectiveness of such interventions.

DISCUSSION

To date there is little evidence that community-based interventions and social marketing campaigns specifically targeting obesity provide substantial or lasting benefit. Concerns have been raised about potential negative effects created by a focus of these interventions on body shape and size, and of the associated media targeting of obesity.

SUMMARY

A more appropriate strategy would be to enact high-level policy and legislative changes to alter the obesogenic environments in which we live by providing incentives for healthy eating and increased levels of physical activity. Research is also needed to improve treatments available for individuals already obese.

The effect of peer influence on the amount of physical activity performed in 8- to 12-year-old boys

The purpose of this study was to determine the amount of physical and sedentary activity normal-weight and at-risk-for/overweight boys perform when alone, with a peer of similar weight and with a peer of different weight. Participants included boys, ages 8-12 years, classified as either normal-weight (<85th BMI percentile; N = 12) or at-risk-for/overweight (<85th BMI percentile; N = 12). At-risk-for/ overweight boys allocated a greater amount of time to sedentary activities and accumulated fewer accelerometer counts than normal-weight boys in the alone condition. Once paired with a peer of either similar or different weight there were no differences between groups. These results indicate the presence of an unknown peer has a positive effect on at-risk-for/overweight children's physical activity behavior.

The use of mentoring programs to improve energy balance behaviors in high-risk children

This study tested the impact of a multicomponent intervention entitled "Partners of all Ages Reading About Diet and Exercise" (PARADE) a child-focused energy balance intervention incorporated into mentoring programs. We used a group randomized nested cohort design randomizing mentoring program sites (n = 119) and children (N = 782; females = 49%; African American = 37%; mean (s.d.) age = 8.5 (1.5) years) to intervention or usual care conditions. PARADE mentors delivered eight lesson plans addressing key concepts related to diet and activity; eight child-focused computer-tailored storybooks with messages targeting that child's diet and activity patterns and eight parent action support newsletters. When compared to the control group, PARADE children were more knowledgeable of diet and activity guidelines (P < 0.01), challenged themselves more to eat five fruits and vegetables (FV) (P < 0.01) and be active 1 h daily (P < 0.01), and to ask for FV for snack (P = 0.015). Calories from high fat foods decreased in overweight/obese children, but not for normal weight children (P = 0.059). There were no significant differences in fruit and vegetable intake, total calories, percent time being active, or BMI z-score. The combination of one-to-one mentoring, child-focused computer based tailoring, and parent support may impact important behavioral change precursors in environments over which the child has control, especially among normal weight children. Further, work is needed to evaluate the impact of family-focused multicomponent interventions, including computer-tailored approaches, directed toward both the parent and the child.
