According to new tests carried out by scientists in New York, initiating the availability of water in cafeterias in schools is likely to have a significant impact in reducing the BMI of students.

Though the decrease was very small, from a statistical point of view, it was quite significant, according to a report published by the researchers of New York University Langone Medical Center. However, the research reveals the possibility of reduction in obesity through the easy availability of water.

Water jets, which are electronically-powered jugs equipped with a push lever, were established by the New York City Department of Health and Mental Hygiene and Department of Education in school lunch lines across 40% schools during 2008-2013. The research revealed that the BMI of boys and girls reduced by 0.025% and 0.022% respectively at the schools where the water jets have been installed for a minimum of three months, as compared to schools where jets were not installed.

The risk of overweight reduction was 0.9% less in boys and 0.6% less in girls where the water jets were installed. Following the outcome of the research, it has been decided that the water jets will be established at all schools in the New York City. "This study demonstrates that doing something as simple as providing free and readily available water to students may have positive impacts on their overall health, particularly weight management," said Dr. Brian Elbel, an Associate Professor at NYU Langone Medical Center.

The cost of installing one water jet will be approximately $1,000. The studies that will now be conducted will concentrate on the comprehensive impact that the reduction in the intake of milk by the children in schools will have on their health. In addition, the future studies will also focus on the long-term impact of installing water jets in schools.
