limitation and reference

I want to rewrite the paragraph with reference to MLA. It should be not a 1 page, just like a paragraph. And Can you also edit the reference with MLA style as well? Thanks 

Obesity in childhood, especially in middle school children between 11 13 years old, is known to have a significant impact on physical and psychological health. According to a study, 19% of males were obesity who compared with 18% of females. The obesity prevalence was 20.3% among 11 to 13 years old, and it occurs to
Hispanic children group who was the most obesity prevalence among 25.6%. Also, the relationship between income and obesity prevalence is vital, which will be occurred to the middle-income group among 19.9%. Of course, all studies have limitations, some may include, the data differences between gender, age, race, and socioeconomic group. The most important limitation may be that kids wont want to improve their health and participate in the interventions. We need to encourage them to be physically active every day for at least 30 minutes, whether through organized sports teams to be exciting to take part in. Keep the kid active at home with everyday activities like playing outside or walking with family.
