Abstract

Background

Adolescents’ technology use is generally associated with food cravings, but it is not clear whether specific types of technology elicit particular types of cravings or whether personal characteristics play a role in these associations.

Objective

We examined whether momentary associations between four technology types (ie, television, video games, computer messaging, and phone messaging) and cravings for unhealthy snack foods and sweetened drinks were moderated by youths’ sex, ethnicity, body mass index, and age.

Methods

Urban adolescents (N=158) aged 14 to 17 years provided momentary information about their technology use and food cravings during the course of 1 week and completed survey reports of their personal characteristics. We used multilevel modeling to determine momentary associations and interactions.

Results

Non-Hispanic adolescents showed stronger associations between television exposure and cravings for sweet snacks, salty snacks, and sweetened drinks. Being Hispanic was associated with stronger associations between phone messaging and cravings for sweet snacks, salty snacks, and sweetened drinks. Males showed stronger associations between video game use and salty snack cravings.

Conclusions

As the public health field continues to monitor the effects of technology use on adolescents’ eating and overall health, it will be important to determine the extent to which these groups are differentially affected by different forms of technology.
