What Causes Young Females Put On Weight?

When we talk about weight gain, we usually relate it to health issues because overweight can lead to a number of medical complications like heart disease, diabetes, high blood pressure, and even cancer. Besides health issues, weight gain is certainly not proud of among young females.

Nevertheless, there are young girls or women find themselves gain in weight although they do not over-eat. Why is this so?

Perhaps the findings of a study published in July 2008 in “The Journal of Pediatrics” may explain. Researchers from Brigham & Women's Hospital and Harvard Medical School in Boston found that girls and young women, who devote much time to Internet, get insufficient sleep, or drink alcohol regularly, are more likely to gain excess weight comparing to their peers.

A total of 5,036 girls and young women between 14 and 21 years old participated in this study, and they were followed for 1 year. They were asked questions like number of recreational hours per week they spent on the Internet (ranging from 1 to 5 hours to 16-plus hours), how long they typically slept each night (anywhere from 5 hours or less, to 9 hours or more), how much alcohol they usually took (ranging from none to 2 or more drinks per week).

The researchers found that if the girls spent more time on the Internet, were lack of sleep and had regular alcohol consumption, their body mass index (BMI) increased. BMI is a measure of weight in relation to height and is commonly used as a gauge for weight gain.

Findings of the study showed that in general, the BMI would rise as Internet use climbed, particularly among young girls age below 18 years old. Those who slept 5 hours or less tended to gain more weight than those who had a standard 8 hours sleep. Moreover, girls and women who had 2 or more alcoholic drinks per week would put on weight than those who drank the least.

The effects over 1 year were modest, for example, a 19-year-old of average weight and height would gain only 4 pounds if she were in the high-risk groups for Internet use, sleep and alcohol consumption. However, the researchers feel that this could eventually translate into significant weight change over time.

Spending hours on the Internet would likely take time away from physical activity thus increasing the weight. Lack of sleep may well cause tiredness to people who may become less active during the day. Sleep deprivation could also affect hormones and metabolism in a way that might help weight gain. Alcohol contains a significant amount of calories. If people, who usually, do not make adjustment for liquid calories by eating or drinking less throughout the rest of the day, their weight would be naturally increased.
