Linked to Internet, Alcohol and Sleep

Girls moving through adolescence may experience unhealthy levels of weight gain, but the reasons for this are not always clear. In fact, many potential causes of weight gain are easily overlooked. A new study soon to be published in “The Journal of Pediatrics” analyses the effect of Internet usage, sleep, alcohol and coffee consumption on weight gain in adolescent girls.

The Growing Up Today Study (GUTS) surveyed more than 5000 girls between the ages of 14 and 21 years from all 50 US states. They asked the girls to reflect on their weekly habits over the past year and report the following: the hours of sleep per night; the time spent on the Internet (excluding time for work or school); the number of alcoholic beverages consumed; and the number of coffee beverages consumed. The girls also reported their height and weight at the beginning and end of the one-year study.

The researchers found that more Internet time, more alcohol consumption, and less sleep resulted in extra weight gain during the study year. Girls aged 18 years or older who consumed two or more alcoholic beverages a week or slept less than six hours a night gained more weight than other study participants.

In fact, when combined with Internet use, girls in this group have the potential to gain four extra pounds a year. The researchers did not find a link between coffee consumption and weight gain, although they point out that this information was collected before high calorie coffee drinks became popular.

The authors suggest that recreational Internet time, alcohol consumption, and lack of sleep may go unnoticed as causes of gradual weight gain. They expressed concern that these behaviors may promote gradual gains in body weight, but the girls and their parents may not understand why. To help maintain a healthy body weight, they encourage adolescent girls to replace recreational Internet time with more sleep, and avoid alcoholic beverage consumption.; Source: Elsevier
