Individual-, family-, community-, and policy-level impact of a school-based cardiovascular risk detection screening program for children in underserved, rural areas: the CARDIAC Project.

The Coronary Artery Risk Detection In Appalachian Communities (CARDIAC) Project has screened more than 80,000 children (10-12 years) for cardiovascular and diabetes risk factors over the past 15 years. Simultaneous referral and intervention efforts have also contributed to the overall program impact. In this study, we examined evidence of programmatic impact in the past decade at the individual, family, community, and policy levels from child screening outcomes, referral rates, participation in subsequent services, and policies that embed the activities of the project as a significant element. Within this period of time, fifth-grade overweight and obesity rates were maintained at a time when rates elsewhere increased. 107 children were referred for additional screening and treatment for probable familial hypercholesterolemia (FH); 82 family members were subsequently screened in family-based screening efforts. 58 grants were distributed throughout the state for community-appropriate obesity intervention. A state wellness policy embedded CARDIAC as the method of assessment and national child cholesterol screening guidelines were impacted by CARDIAC findings. The sustainability and successful impact of this school-based program within a largely underserved, rural Appalachian state are also discussed.

Universal versus targeted blood cholesterol screening among youth: The CARDIAC project.

OBJECTIVES: The goal was to determine the sensitivity and specificity of family history in identifying children with severe or genetic hyperlipidemias in a rural, predominantly white population. METHODS: A total of 20,266 fifth-grade children in West Virginia, from the Coronary Artery Risk Detection in Appalachian Communities (CARDIAC) Project, who completed a family history and fasting lipid profile were used in analyses. The relationship between hyperlipidemia and family history was determined, and the use of family history to predict the need for pharmacologic treatment among children with dyslipidemia was evaluated. RESULTS: A total of 71.4% of children met the National Cholesterol Education Program (NCEP) guidelines for cholesterol screening on the basis of positive family history. Of those, 1204 (8.3%) were considered to have dyslipidemia (low-density lipoprotein > or =130 mg/dL), and 1.2% of these children with dyslipidemia warranted possible pharmacologic treatment (low-density lipoprotein > or =160 mg/dL). Of the 28.6% who did not have a positive family history (did not meet NCEP guidelines), 548 (9.5%) had dyslipidemia, 1.7% of whom warranted pharmacologic treatment. Sensitivity and specificity data demonstrated that family history does not provide a strong indication as to whether pharmacologic treatment may be warranted. CONCLUSIONS: Results indicate that the use of family history to determine the need for cholesterol screening in children would have (1) missed many with moderate dyslipidemia and (2) failed to detect a substantial number with likely genetic dyslipidemias that would require pharmacologic treatment. The use of universal cholesterol screening would identify all children with severe dyslipidemia, allowing for proper intervention and follow-up and leading to the prevention of future atherosclerotic disease.

Sleep-disordered breathing symptoms frequency and growth among prematurely born infants.

BACKGROUND: Children who were born prematurely are at higher risk for sleep-disordered breathing (SDB) compared to their same-age peers who were born fullterm. OBJECTIVE: The objective of the present study was to assess the frequency of SDB symptoms and effects on growth among preterm infants while they are still infants, with a goal of identifying risk factors to facilitate prevention and early intervention. METHODS: The Louisville pediatric SDB risk survey was administered to the primary caretakers of prematurely born infants attending the Neonatal Follow-Up Clinic at West Virginia University Children's Hospital. RESULTS: Participation was 100% among 173 consecutive patients invited to participate in the study. At 9.13 months corrected age, 8.1% of infants born at a mean of 31.6 weeks gestation were reported to snore > or = 3 days/week, a rate consistent with diagnosis of sleep-disordered breathing among older children. A composite of nine parent-reported symptoms was created based on factor analysis. Birth weight and size for gestational age at birth did not differ between snoring groups or correlate with the composite score. But a significant negative correlation between the composite risk for SDB score and current weight for adjusted age percentile score indicate that infants with higher SDB symptom profiles have lower weight for age (r=-.18, p=.028). CONCLUSIONS: SDB symptoms are detectable among infants born preterm, while they are still infants. Because of their preferential risk for SDB and its somatic consequences, a primary research goal should be description of the natural history of SDB and identification of modifiable risk factors and treatment options.

Primary care of the premature infant discharged from the neonatal intensive care unit.

Premature infants require varying degrees of newborn intensive care and have a wide range of physical and developmental outcomes. Subsequent ambulatory care for these infants is often complex. Although tertiary hospitals often provide multidisciplinary follow-up clinics, the pediatric nurse practitioner (PNP) responsible for primary care has a unique opportunity to influence the lives of these special babies and their families. While the basic principles of well child care and health maintenance apply to this special population, there are several inherent challenges. The transition from neonatal intensive care unit (NICU) to home can be stressful for families. Infants born prematurely often have unpredictable behavior and present with cues that are vague and unclear to caregivers. Growth must be monitored adjusting for prematurity, and nutrition must be tailored to the physical and developmental level of the infant. Assessments of development, vision, and hearing must also be adjusted for prematurity. Fortunately, the majority of premature infants discharged from the NICU thrive and develop normally. However, some will experience medical problems and developmental delay. Knowledge of complications common to premature infants will be helpful to the PNP providing primary care. These include difficulties of growth and feeding, gastroesophageal reflux, apnea and bradycardia, chronic lung disease, fine and gross motor abnormalities, and other learning problems. Providing care to the NICU graduate is one of the challenges faced by PNPs in primary care, but one that is both rewarding and enjoyable.
