Media Use in Preschooler Study (MUPS)

Childhood obesity is an epidemic and increasing. There are very few effective treatments for obesity in children. Recent studies have shown an association between obesity and sedentary behaviors such as television, video viewing and playing video games ('screen time') in preschool aged children. A school based intervention to reduce screen time in older children has been effective in preventing obesity.

The reduction of screen time may lead to the prevention of obesity and its complications in preschool children.


There have been no trials examining an intervention to decrease screen time in preschool children in the physician office setting. This setting is appealing for interventions directed to preschool children because of accessibility. In addition, other public health interventions implemented in a physician office setting, such as home safety advice, have been effective.

The proposed study design will be a randomized controlled trial. The intervention group will receive the study intervention, which is a 15 minute session about the health impact of screen time in children and strategies to decrease screen time.

The objective of this study is to determine if an office based intervention is effective in decreasing screen time (television, video viewing and playing video games) in preschool children.

Medical and Biotech [MESH] Definitions

Screens which absorb the energy in the x-ray beam that has penetrated the patient and convert this energy into a light pattern which has as nearly as possible the same information as the original x-ray beam. The more light a screen produces for a given input of x-radiation, the less x-ray exposure and thus shorter exposure time are needed to expose the film. In most film-screen systems, the film is sandwiched between two screens in a cassette so that the emulsion on each side is exposed to the light from its contiguous screen.

Education via communication media (correspondence, radio, television, computer networks) with little or no in-person face-to-face contact between students and teachers. (ERIC Thesaurus, 1997)

Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.

The decrease in the cell's ability to proliferate with the passing of time. Each cell is programmed for a certain number of cell divisions and at the end of that time proliferation halts. The cell enters a quiescent state after which it experiences CELL DEATH via the process of APOPTOSIS.

Culture media containing biologically active components obtained from previously cultured cells or tissues that have released into the media substances affecting certain cell functions (e.g., growth, lysis).
