How Screen Time Affects Greek Schoolchildren's Eating Habits and Functional Food Consumption?-A Cross-Sectional Study.

BACKGROUND

Television (TV), video games, PC and devices such as tablets and smart phones have become part of everyday life at an ever-younger age. Increased screen time correlates with unhealthy eating habits among children.

METHODS

374 children aged 9-12 years and their parents (n = 159), from 3 schools in Lemnos and 5 schools in Thessaloniki, Greece, took part in this cross-sectional study. The children completed the KIDMED score and a questionnaire about their physical activity, time spent watching TV, PC and playing electronic games, the frequency of cooking or shopping with their parents, the frequency of eating fast food, soft drinks and Functional Foods (FFs). Statistical analysis was performed with SPSS-29.0, using One Way ANOVA and Pearson chi-square.

RESULTS

As the hours of TV viewing increased, so did the percentage of children who consumed soft drinks ( = 0.03). A statistically significant association detected between television ( = 0.024), video games ( = 0.028), all screen categories ( = 0.011) and fast-food consumption. Increased screen time is associated with a higher weekly consumption of fast food ( = 0.011). The more hours children spent in front of screens, the less adherence they had to the Mediterranean Diet ( = 0.001) and less natural FFs consumption ( = 0.001).

CONCLUSIONS

The results suggest that screen time seems to affect children's eating behaviors. The study concluded that the longer the screen time, the unhealthier the dietary habits of schoolchildren become. Future research should focus on reducing screen time, as a means of improving dietary patterns and potentially reducing childhood obesity.
