Student Weight Status

Ketchikan Gateway Borough School District

 

 District Summary

Over the 2013-14 school year, Ketchikan Gateway Borough School District staff measured the height and weight of 1,565 students (88% of all enrolled) in grades pre-Kindergarten through 9th.  With measurement results scaled to represent each grade’s enrolled population:

·       19.5% of students were overweight (BMI 85th-95th percentile)

·       22.6% of students were obese (BMI ≥ 95th percentile)

·       6.5% of students were severely obese, with a  BMI ≥120% of the 95th percentile

·       The prevalence of overweight/obesity was slightly higher among male students

(44.2%) than among females (39.8%)

 

Weight Status by Grade

The percentage of students either overweight or obese was highest amongst 6th-grade students, as was the prevalence of obesity alone.  These percentages were lowest among pre-Kindergarten students.  Over 15% of students in all of grades 1 through 9 were obese.

 

 

 

Disparities in Weight Status

 Reporting by race allows us to identify racial disparities in order to address and reduce them. The prevalence of obesity among White students (19.7%) was slightly lower than among American Indian / Alaska Native students (24.1%) and significantly lower than among students of other races (28.0%).  There was no disparity in obesity prevalence between schools with at least 45% of students enrolled in the free or reduced-price lunch program (22.5%) and other schools (22.6%) (see Table 4).
