First lady Michelle Obama took her campaign against childhood obesity to the popular Spanish-language television program "Sabado Gigante," where she spoke about the benefits of a healthy diet and physical exercise.

In a brief pre-recorded video dubbed into Spanish, Obama urged Hispanic families to adopt a healthy diet, to involve their children in the cooking duties and to encourage them to get plenty of exercise.

According to the American Medical Association, 38.2 percent of Hispanic kids between the ages of 2 and 19 are overweight or obese, compared to 31.7 percent of all children in the general population.

Hispanic males between those ages are more prone to be overweight or obese than white or black boys.

More Hispanic boys and girls between the ages of 2 and 11 are obese than white or black kids.

Obama launched the "Let's Move" nationwide educational campaign to fight this public health problem, which costs the country billions of dollars per year in chronic diseases and other health problems.
