Abstract

Background: Children with overweight status and obesity seek care for acute illnesses more often than normal weight peers. School-based health centers (SBHCs) have a role in acute and chronic disease management; however, little is known about SBHC use by children with overweight status and obesity. This study compared SBHC utilization by student body mass index (BMI) category and investigated whether SBHC visit diagnoses varied by BMI category. Methods: We performed a retrospective analysis of students (n = 1161) in grades K-8 enrolled in a large SBHC for 2 years. Negative binomial regression models were used to test the independent association between BMI category as defined by BMI percentile [normal/underweight (BMI percentile <85%) and overweight/obesity (BMI percentile ≥85%), either overweight (85% ≤BMI percentile <95%) or obesity (BMI percentile ≥95%)], and the number of SBHC visits (nurse, clinician, and total visits) for the 2-year interval. Top five diagnoses based on ICD-10 visit codes were compared. Results: Students in the overweight/obesity category (BMI percentile ≥85%) had higher visit rates than normal/underweight peers after adjusting for age and gender, but only total visits were statistically significant [nurse: incident rate ratio (IRR) 1.42 (95% CI 0.94-2.15); clinician: 1.27 (95% CI 0.93-1.75); total: 1.45 (95% CI 1.02-2.07)]. Visit diagnoses were similar by BMI category. Conclusions: Students with higher BMI percentiles, categorized as overweight/obesity, had higher SBHC utilization than normal/underweight peers, but visit diagnoses were similar. This higher utilization may provide an as-yet untapped opportunity to expand school-based obesity prevention and management.
