Drinking carbonated beverages frequently can disrupt the sleep of teenagers! Lancet sub-published a study in 64 countries

On December 21, a study covering 64 countries published in the Lancet's electronic clinical medicine journal suggested that for teenagers, frequent consumption of carbonated soft drinks and fast food are associated with sleep disorders.

Relationship between different frequencies of fast food consumption (a) and carbonated soft drink consumption (b) and sleep disturbances

After adjusting for multiple potential confounding factors, meta-analysis showed that adolescents who drank ≥ 3 carbonated soft drinks per day were more than 50% more likely to report sleep disorders compared with adolescents who drank less than 1 carbonated soft drink per day, with an increase of 55% and 51% in boys and girls, respectively.

Compared with adolescents who ate fast food no more than one day a week, adolescents who ate fast food at least four days a week were at least 50% more likely to report sleep disturbances, with an increase of 55% for boys and 50% for girls.

In all countries except low-income countries, drinking carbonated soft drinks at least three times a day and eating fast food at least four days a week were significantly associated with sleep disturbance in both boys and girls.

Among them, boys from high-income countries who drank carbonated soft drinks at least three times a day were most likely to report sleep disorders (OR=1.67), and boys from middle- and high-income countries who ate fast food at least four days a week were most likely to report sleep disorders (OR=1.62).

Among girls who drank carbonated soft drinks at least three times a day or ate fast food at least four days a week, girls from high-income countries were most likely to report sleeping poorly, with increases of 68% and 75%, respectively.

Additionally, the researchers found that drinking one to two carbonated soft drinks per day was not associated with stress-related sleep disturbances.

In low- and middle-income countries, as well as in upper-middle-income countries, Southeast Asia, and the Western Pacific, girls who ate fast food 2 to 3 days per week had an 18% increased risk of stress-related sleep disturbances.

The researchers pointed out that the results of the study show that unhealthy diet can affect the physical and mental health of adolescents.

The study included 175,000 adolescents aged 12 to 15 from 64 countries from the Global School-Based Student Health Survey Database. The average age was 13.8 years old and 48.5% were girls.

The survey results showed that 7.5% of adolescents reported having sleep disorders within one year, with the proportions among boys and girls being 6.6% and 8.4% respectively.

Among students who drank carbonated soft drinks at least three times a day, 9.6% of boys and 13.6% of girls reported sleep disturbances;
