espect to specific patient populations<br />

contained within the survey.<br />

Pediatricians were statistically more<br />

likely than family practitioners to<br />

routinely offer screening for all<br />

categories except those children<br />

with no traditional cardiovascular<br />

risk factors. Very few practitioners<br />

routinely offered screening to<br />

children belonging to this category.<br />

Interestingly, 33% of pediatricians<br />

and 67% of family practitioners<br />

did not routinely offer screening<br />

to children between the ages of 2<br />

and 10, which is part of the 2008<br />

AAP policy update. Furthermore,<br />

11% of pediatricians and 35% of<br />

family practitioners in the sample<br />

do not routinely offer screening for<br />

hyperlipidemia to children at all.<br />

Discussion<br />

The results of this survey-based<br />

study illustrate that screening<br />

children for hyperlipidemia appears<br />

to be a sporadic practice in <strong>West</strong><br />

<strong>Virginia</strong>. With less than half of<br />

the sampled practitioners in the<br />

state screening children according<br />

to the guidelines within the new<br />

AAP policy update, it appears<br />

that this update has not yet been<br />

able to diminish the controversy<br />

surrounding this topic. Furthermore,<br />

nearly 25% of practitioners in the<br />

study did not screen children at all.<br />

Family practitioners in general, were<br />

less likely to screen according to the<br />

guidelines than pediatricians were.<br />

This may be due in large part to two<br />

separate factors: family practitioners’<br />

unfamiliarity with the new guideline<br />

and the fact that the American<br />

Academy of Family Practice has<br />

no official stance on screening<br />

children for hyperlipidemia.<br />

It still remains unclear whether or<br />

not the portion of the AAP guideline<br />

related to age at first screening is<br />

absolutely essential. While most<br />

practitioners did not offer screening<br />

to children between the ages of<br />

two and ten, the majority did offer<br />

screening to children over the age of<br />

10. Does waiting until after the age<br />

of 10 to screen for and potentially<br />

identify hyperlipidemia contribute<br />

any potential morbidity to children?<br />

Interestingly, when looking at the<br />

guidelines for screening adults, all<br />

major agencies note that screening<br />

should take place at some point in<br />

time but they all differ on when the<br />

initial screening should take place. 8,9<br />

This study is one of the first<br />

known studies to look at the<br />

practice of screening children for<br />

hyperlipidemia among primary care<br />

providers not only in <strong>West</strong> <strong>Virginia</strong>,<br />

but in the United <strong>State</strong>s. A fairly<br />

reasonable sample size was able to<br />

be generated and a comprehensive<br />

picture of screening practices and<br />

knowledge among primary care<br />

providers was able to be painted.<br />

However, there are a few<br />

limitations within this study. As with<br />

most survey-based studies, results<br />

are drastically influenced and limited<br />

by the survey response rate. Just<br />

over half of eligible pediatricians<br />

responded in our study. Furthermore,<br />

less than half of eligible family<br />

practitioners responded, but this<br />

is likely artificially low as many<br />

family practitioners who do not<br />

see children likely did not respond.<br />

Although the geographic spread<br />

of respondents was quite high<br />

within <strong>West</strong> <strong>Virginia</strong>, generalizing<br />

results to all practitioners in the<br />

state must be handled with caution<br />

given the modest response rate.<br />

Family practitioners did outnumber<br />

pediatricians within the study almost<br />

2:1. While this in fact may represent<br />

the true proportion of these particular<br />

specialties in <strong>West</strong> <strong>Virginia</strong>, it also<br />

may have slightly skewed the<br />

results as family practitioners were<br />

less likely to screen children than<br />

pediatricians. Also, as with any<br />

survey-based study, practitioners<br />

may have not answered with veracity<br />

as potential feelings of inadequate<br />

patient care may have surfaced<br />

while perusing the questions.<br />

What does remain clear is that<br />

further studies regarding the<br />

outcomes of children who are<br />

diagnosed with hyperlipidemia<br />

are needed to help streamline<br />

guidelines for screening. Until then,<br />

controversy regarding this topic<br />

and concomitant sporadic screening<br />

practices will continue to exist.<br />
