Insights
Eating breakfast and snacks while watching television (TVV) is linked to increased waist circumference, blood sugar, and blood pressure in children. Excessive TVV also negatively impacts these cardio-metabolic risk factors.
Area of Science:
- Pediatric Health
- Cardio-metabolic Risk Assessment
- Behavioral Science
Background:
- Childhood obesity and cardio-metabolic risk factors are growing public health concerns.
- Sedentary behaviors, including screen time and eating while watching television (TVV), are prevalent among school-aged children.
- Understanding the link between these behaviors and health outcomes is crucial for developing effective interventions.
Purpose of the Study:
- To investigate the association between eating meals during TVV and screen-based behaviors with cardio-metabolic risk factors (CRFs) in primary school children.
- To identify specific meal patterns during TVV that correlate with adverse health indicators.
- To assess the impact of overall TVV duration on children's health.
Main Methods:
- Cross-sectional study involving 409 primary school children (ages 6-9) in Shiraz.
- Data collected via questionnaires on screen time, TVV frequency, and dietary intake.
- Assessed anthropometric indices, fasting blood sugar (FBS), blood lipids, blood pressure (BP), and physical activity.
Main Results:
- TVV duration showed a significant positive association with waist circumference (WC) and blood pressure (BP).
- Eating breakfast or snacks while TVV was linked to higher WC, FBS, and systolic BP.
- Computer and video game use inversely correlated with triglyceride (TG) levels.
Conclusions:
- Eating breakfast and snacks while TVV are associated with increased WC, FBS, and BP in children.
- Excessive TVV is independently linked to adverse WC and BP outcomes.
- These findings highlight the importance of mindful eating habits and limiting screen time in childhood.
Aim:
We aimed to investigate the association of eating meals while television viewing (TVV) and screen-based behaviors with cardio metabolic risk factors (CRFs) among school-aged children in Shiraz.
Materials And Methods:
This cross-sectional study was done on 409 primary school children (217 boys), aged 6-9 years. Physical activity, time spent on screen-based behaviors and frequency of eating meals while TVV were measured using a questionnaire. Anthropometric indices, fasting blood sugar (FBS), blood lipids, blood pressure (BP), dietary intakes and physical activity were assessed. Association of eating while TVV with CRFs were assessed using linear regression, adjusted for potential confounders. All statistical analysis were conducted using the Stata 13 software.
Results:
Fully adjusted model showed that TVV time had significant positive association with waist circumferences (WC), and BP (p <0.05). Also, we found an inverse relationship between using Computer and Video games with TG level (β=-0.3; CI: -0.64, -0.09). Children who ate two or more breakfast meal while TVV had higher WC (β=2.02; CI: 0.51, 3.53) and FBS (β=3.58; CI: 0.39, 6.78) compared to who never ate breakfast while TVV. After adjustment for Screen time and BMI, eating snacks while TVV was positively associated with FBS and systolic BP. However, Eating dinner and lunch while TVV were not significantly associated with any of CRFs after adjustment for confounders.
Conclusions:
We found that both eating breakfast and snacks while TVV were associated with WC, FBS and BP in children. Also, excessive TVV was associated with WC and BP.
