A comparison of blood pressure, body mass index, and acanthosis nigricans in school-age children

Abstract

The purpose of this retrospective quantitative study was to examine the relationships among acanthosis nigricans (AN), body mass index (BMI), blood pressure (BP), school grade, and gender in children attending elementary school located in South West Texas. Data were collected by attending school district nurses. Researchers reviewed 7,026 previously collected records from a state mandated public school health screening program in elementary school Grades 3, 5, 7, and 9, conducted by school nurses. Of 7,026 records, 6,867 were included for the secondary analysis. A logistic regression analysis was carried out with the AN marker as the dependant variable and school grade, gender, BMI, and BP as the independent variables. The results of the study suggest that a direct relationship exists between the AN marker, BMI, and BP in school-age children. Further study is warranted based on the number of school-age children who are now found to be obese.
