Cross-sectional associations between body mass index and social-emotional wellbeing among differentially active children

A cross-sectional analysis between physical activity levels, weight status and empathy-related behaviors in a sample of Tuscany primary school children

BACKGROUND

The present study aimed to investigate the relationship between physical activity (PA) and the development of relational empathy skills in children, taking into account weight status.

METHODS

Parents/guardians of primary school children were involved in filling out a questionnaire: the Empathy Questionnaire (EmQue-I13) and children were asked to complete the Physical Activity Questionnaire for Children (PAQ-C) to investigate the self-reported PA levels. The weight status was assessed using a self-reported Body Mass Index (BMI).

RESULTS

Three hundred seventy parents or guardians of students who attended primary school (8.53±1.61 yrs) were recruited. The total score was 2.41±0.89 for PAQ-C and 41.17±6.32 for EmQue-I13. The three domains of EmQue-I13 were: contagion (8.16±2.67), attention to others' feelings (19.40±2.99) and prosocial actions (13.62±3.01). Linear regression models showed that a higher PAQ-C score was positively associated with empathy-related total score P<0.000. Weight status, age and gender were not associated with EmQue-I13.

CONCLUSIONS

Our results underline the positive association between physical activity and the development of relational empathic skills.

The Influence of Adolescent Sport Participation on Body Mass Index Tracking and the Association between Body Mass Index and Self-Esteem over a Three-Year Period

This study aimed to (1) investigate gender-specific characteristics associated with low sport participation among UK adolescents, and (2) assess gender-specific BMI tracking, and gender-specific associations between BMI and self-esteem based on different levels of adolescent sport participation. Participants were 9046 (4523 female) UK adolescents. At 11- and 14 years self-esteem was self-reported and BMI was calculated from objectively measured height and weight. At 11- years sport participation was parent-reported. Gender-specific sport participation quartile cut-off values categorised boys and girls separately into four graded groups. Gender-specific χ² and independent samples t tests assessed differences in measured variables between the lowest (Q1) and highest (Q4) sport participation quartiles. Adjusted linear regression analyses examined BMI tracking and associations between BMI and self-esteem scores. Gender-specific analyses were conducted separately for sport participation quartiles. Compared to Q4 boys and girls, Q1 boys and girls were more likely to be non-White, low family income, have overweight/obesity at 11 years and report lower self-esteem at 11 years and 14 years. BMI at 11 years was positively associated with BMI at 14 years for boys and girls across sport participation quartiles. BMI at 11 years was inversely associated with self-esteem scores at 11 years for Q1 and Q2 boys, and Q1 and Q4 girls. BMI at 11 years was inversely associated with self-esteem scores at 14 years for Q1, Q3 and Q4 boys, and Q1, Q2, Q3 and Q4 girls. Gender and sport participation influence BMI tracking and the BMI and self-esteem association among adolescents.

Academic performance and psychosocial functioning in European schoolchildren: The role of cardiorespiratory fitness and weight status

BACKGROUND

Whether a high cardiorespiratory fitness (CRF) can attenuate the potential detrimental effect of childhood obesity on academic performance and particularly psychosocial functioning remains unclear.

OBJECTIVES

To analyse the academic performance/psychosocial functioning of schoolchildren attending to their CRF and weight status.

METHODS

470 schoolchildren (46% girls, 7 ± 0 years) from 20 schools in five European countries were categorized as (i) having overweight/obesity (n = 113) or normal weight (n = 357) attending to body mass index and (ii) 'fit' (n = 282) or 'unfit' (n = 188) based on 20-meter shuttle-run performance (CRF ≥ or <42 ml·kg^-1 ·min^-1 [boys] and 35 ml·kg^-1 ·min^-1 [girls], respectively). Academic performance and psychosocial functioning were assessed using the grades attained in school subjects and the Strengths and Difficulties Questionnaire (SDQ) for parents, respectively.

RESULTS

Independent of their weight status, fit children showed a greater academic performance and psychosocial functioning than their peers who were unfit and overweight/obese. In fit children, academic performance and psychosocial functioning did not differ between the two weight status categories (normal weight or overweight/obesity).

CONCLUSIONS

Children with a higher CRF show a greater performance achievement and psychosocial functioning regardless of their weight status, thereby supporting the 'fat but fit' paradox and reinforcing the importance of improving CRF in this population.

Adolescent time use and mental health: a cross-sectional, compositional analysis in the Millennium Cohort Study

OBJECTIVE

To examine the association of 24-hour time-use compositions with mental health in a large, geographically diverse sample of UK adolescents.

DESIGN

Cross-sectional, secondary data analysis.

SETTING

Millennium Cohort Study (sixth survey), a UK-based prospective birth cohort.

PARTICIPANTS

Data were available from 4642 adolescents aged 14 years. Analytical samples for weekday and weekend analyses were n=3485 and n=3468, respectively (45% boys, 85% white ethnicity).

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary outcome measures were the Strengths and Difficulties Questionnaire (SDQ, socioemotional behaviour), Mood and Feelings Questionnaire (MFQ, depressive symptoms) and Rosenberg Self-Esteem Scale (RSE, self-esteem). Behavioural exposure data were derived from 24-hour time-use diaries.

RESULTS

On weekdays, participants spent approximately 54% of their time in sleep, 3% in physical activity, 9% in school-related activities, 6% in hobbies, 11% using electronic media and 16% in domestic activities. Predicted differences in SDQ, MFQ and RSE were statistically significant for all models (weekday and weekend) that simulated the addition or removal of 15 min physical activity, with an increase in activity being associated with improved mental health and vice versa. Predicted differences in RSE were also significant for simulated changes in electronic media use; an increase in electronic media use was associated with reduced self-esteem.

CONCLUSION

Small but consistent associations were observed between physical activity, electronic media use and selected markers of mental health. Findings support the delivery of physical activity interventions to promote mental health during adolescence, without the need to specifically target or protect time spent in other activities.
