Effectiveness of an Intervention Regarding Weight Status of Selected New Mexico Kindergarten Children and their Parent’s Perceptions

Abstract

The purpose of this study was to analyze pre-existing data of selected kindergarten children in New Mexico regarding the relationship between measured body mass index (BMI) and parents/guardians selfreported perceptions of their child’s weight status. The study is unique because it gives the opportunity to gauge the effectiveness of an intervention that is tailored to a child’s BMI. A total of six districts and 35 schools agreed to participate during this 2004-05 study. A total of 1,480 kindergarten children had their BMI measured by the school nurses. Two instruments were used to conduct the study, a bilingual pre- and post-intervention survey, and the CDC’s gender-specific body mass index for age percentile charts. The intervention materials included only literature for the parent/guardian to read. The largest variation in changes of perception occurred in the borderline categories of at risk of overweight and underweight. On the pre-intervention survey, 10% of the survey respondents accurately described their child as at risk of overweight and increased to 47% on the post- intervention survey. A total of 11% of survey respondents accurately described their child’s weight status as underweight on the pre- intervention survey and this increased to 23% on the post-intervention survey. This study was a seminal attempt to obtain information regarding childhood obesity in the state of New Mexico, particularly among kindergarten children. Interventions regarding childhood obesity should be tailored to the parent/guardian as well as the child. Different interventions are needed for parents/guardians of children in the definitive categories of overweight and normal weight than for those parents/guardians of children who are at risk of overweight and underweight.
