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.

This retrospective quantitative study examined the relationships among gender, Acanthosis Nigricans (AN), body mass index (BMI), and blood pressure (BP) in children attending school Grades 1-9 in Southwest Texas. Of the 34,897 health screening records obtained for the secondary analysis, 32,788 were included for the study. A logistic regression analysis was carried out with AN as the dependent variable, with year, gender, BMI, and BP as independent variables. The results indicate that the rate of children in each grade with three positive markers increased 2% during a 3-year period between 2008 and 2010. In the 5-year period between 2005 and 2010, a clear trend of significantly higher numbers of children with both AN and BMI markers was apparent. Gender played a significant role as females were more likely to have the AN marker than males. Further study is indicated based on the increasing trend of school-age children in Texas with positive markers for AN, increased BMI and BP.
