Insights
Parental perception of child weight status and support for school BMI screening varies by race/ethnicity, parent weight, and child age. These factors influence how parents view and support body mass index (BMI) screening in schools.
Area of Science:
- Pediatric obesity
- Public health
- Health disparities
Background:
- Parental underestimation of child weight status is a significant barrier to addressing childhood obesity.
- Understanding parental attitudes towards school-based body mass index (BMI) screening is crucial for effective implementation.
Purpose of the Study:
- To identify predictors of parental underestimation of child weight status.
- To examine factors associated with parental support for school-based BMI screening and reporting.
Main Methods:
- A mailed survey was administered to 1002 parents of 3rd to 7th graders in The Fit Study.
- Data collected included parent race/ethnicity, weight status, perception of child's weight status, and support for BMI screening/reporting.
Main Results:
- Most parents underestimated their child's overweight or obese status.
- Support for BMI screening was higher among Hispanic, Asian, and Black parents compared to White parents.
- Support for BMI reporting decreased with increasing child grade level.
Conclusions:
- Parental race/ethnicity, parent weight status, and child age are significant predictors of support for school-based BMI screening and reporting.
- Findings highlight the need for culturally tailored approaches to childhood obesity interventions.
Objective:
In this study, we identify predictors of parental underestimation of child weight status and support for school-based BMI screening and reporting.
Methods:
Parents of 3rd through 7th grade students (N = 1002) participating in The Fit Study completed mailed surveys assessing parent race/ethnicity, weight status, perception of child weight status, and preference for BMI screening and reporting.
Results:
Only 33% and 6% of parents classified their overweight child as somewhat overweight and their obese child as very overweight, respectively. Support for BMI screening was stronger among Hispanic (OR = 2.3, p < .001), Asian (OR = 3.7, p < .001), and black (OR = 2.3, p = .04) parents than white parents and weaker among overweight versus normal-weight parents (OR = 0.6, p = .01). Compared to parents of 3rd grade students, parents of older children reported less support for BMI reporting (4th grade: OR = 0.4, p = .04; 6th grade: OR = 0.3, p = .02; 7th grade: OR = 0.3, p = .03).
Conclusions:
Parent race/ethnicity, parent weight status, and child age are associated with support for BMI screening and reporting..
