Insights
Higher body mass index (BMI) is linked to social-emotional wellbeing (SEW) difficulties in less active children, but not in highly active children. This highlights the importance of physical activity for children's emotional health.
Area of Science:
- Child Health
- Developmental Psychology
- Public Health
Background:
- Investigating the relationship between body mass index (BMI) and social-emotional wellbeing (SEW) in children is crucial for understanding developmental health.
- Physical activity levels can influence both weight status and emotional health in children.
Purpose of the Study:
- To assess gender-specific associations between body mass index (BMI) and social-emotional wellbeing (SEW) in seven-year-old children.
- To explore how different levels of physical activity moderate the relationship between BMI and SEW.
Main Methods:
- Utilized data from the UK Millennium Cohort Study (N=6011) with objective physical activity measures (accelerometry) and parent-reported emotional and behavioral outcomes (Strengths and Difficulties Questionnaire).
- Calculated BMI and categorized children into physical activity quartiles (least to most active) separately for boys and girls.
- Employed adjusted linear regression analyses to examine gender-specific associations between BMI and SEW across physical activity levels.
Main Results:
- Body mass index (BMI) showed positive associations with peer problems in lower to moderately active boys and girls.
- Conduct problems were linked to higher BMI in moderately and highly active boys, while emotional problems and prosocial behavior were associated with BMI in moderately active boys.
- Total difficulties were associated with higher BMI in less active girls and moderately active boys.
Conclusions:
- Body mass index (BMI) is positively associated with social-emotional wellbeing (SEW) difficulties primarily among less physically active children.
- The findings suggest that higher physical activity may buffer the negative impact of BMI on SEW in children.
- Further research is recommended to investigate the combined effects of diet, physical activity, and weight status on children's SEW.
Background:
This study assessed gender-specific associations between body mass index (BMI) and social-emotional wellbeing (SEW) among differentially active seven-year-old children.
Methods:
Data are from wave four of the UK Millennium Cohort Study, collected in 2007-08. Children wore an ActiGraph accelerometer for seven consecutive days and measures of stature and body mass were taken. BMI was calculated from stature and body mass (kg/m2). Parents/carers completed the strengths and difficulties questionnaire (SDQ). A total of 6011 children (3073 girls) had completed data. Mean minutes per day spent in moderate-to-vigorous intensity physical activity (MVPA) were calculated for each child. Gender-specific MVPA quartile cut-off values categorized boys and girls separately into four graded groups representing the least (Q1) through to the most active (Q4) children. Adjusted linear regression analyses examined associations between BMI and SDQ scores. Gender-specific analyses were conducted separately for MVPA quartiles.
Results:
BMI was positively associated with peer problems for Q1 and Q2 boys and girls, conduct problems for Q2 and Q4 boys, emotional problems and prosocial behaviour for Q2 boys and total difficulty scores for Q1 girls and Q2 boys (P < 0.05).
Conclusions:
Our results revealed that BMI was positively associated with SEW difficulties among the low active children but not the high active children. Further research examining the concurrent effect of diet and MVPA on child weight status and SEW is needed.
