请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。 注意：每个空格只填1个单词。请将答案写在答题卡上相应题号的横线上。 The United States is facing a growing concern: rising obesity(肥胖) rates. A new report says adult obesity rates rose last year in 23 of the 50 states. And, the percentage of obese children was at or above 30% in 30 states. Mississippi had the highest rate of adult obesity in the new study. 32.5% of the state’s adults were obese. Mississippi also had the highest rate of obese and overweight children. 44.4% of all children between the ages of ten and seventeen years were obese or overweight.

Obesity is also responsible for an increasing part of health care costs in the United States. Health care costs have grown while many Americans are getting fatter.
