The Impact of Asymptomatic Congenital Cytomegalovirus on Adult Quality of Life.

OBJECTIVE: Children born with asymptomatic congenital cytomegalovirus infection (AcCMV) have increased risk for hearing loss, which may affect their quality of life into adulthood. We aim to determine quality of life outcomes among adults who were identified at birth with AcCMV compared with controls, using the cohort of the Houston Congenital CMV Longitudinal Study. METHODS: Quality of life was determined using the self-reported Quality of Life Inventory (QOLI). Sixty-one of 109 AcCMV subjects and 23 of 51 controls completed QOLI. Percentile scores of subjects were compared with percentile scores of controls using Student t tests. QOLI percentile scores were compared among AcCMV subjects with (N = 14) and without hearing loss (N = 47). RESULTS: There was no difference in mean percentile scores on QOLI between AcCMV subjects (59.8 [SD = 27.6]) and controls (57.3 [SD = 35.3]; p = 0.754). Percentile scores indicate an average overall quality of life classification for AcCMV subjects and controls. There was no difference in mean percentile scores on the QOLI between AcCMV subjects with and without hearing loss (54.8 [SD = 25.2]) and 61.3 [SD = 28.3]; p = 0.440, respectively). CONCLUSION: Adults born with AcCMV do not seem to have lower ratings of quality of life compared with uninfected controls. Although our study had small sample size, hearing loss does not seem to be a significant predictor of QOLI percentile scores among AcCMV subjects. Quality of life in adulthood does not seem to be affected by an individual's awareness of screening positive for CMV, which supports the notion of "no harm" occurring from universal newborn screening for congenital CMV infection.

Inattention and Hyperactivity in Children with Symptomatic and Asymptomatic Congenital Cytomegalovirus.

OBJECTIVES: To explore the relationship between congenital cytomegalovirus (CMV) and inattention and hyperactivity among school-aged children. METHODS: The Behavior Assessment System for Children, Second Edition, parent- and self-report, was completed among children with symptomatic congenital CMV (ScCMV) (n = 36), asymptomatic congenital CMV (AcCMV) (n = 76), and controls (n = 29) enrolled in a longitudinal cohort. The proportions of children with ScCMV, AcCMV, and controls with Attention Problems or Hyperactivity T-scores ever ≥ 65 were compared. Mean T-scores in these domains were also compared and adjusted for IQ. RESULTS: Children with AcCMV did not differ from controls in the proportion of children with elevated Attention Problems or Hyperactivity T-scores or in mean Attention Problems or Hyperactivity T-scores. Children with ScCMV had a higher proportion of elevated Attention Problems T-scores compared with the AcCMV group but not controls. There were no differences in the proportions of children with elevated Hyperactivity T-scores between ScCMV and AcCMV or control groups. Children with ScCMV had higher mean Attention Problems T-scores versus those with AcCMV and controls and higher mean Hyperactivity T-scores versus those with AcCMV but not controls. After adjustment for IQ, differences in mean Attention Problems or Hyperactivity T-scores were no longer significant. CONCLUSION: Children with AcCMV are not at increased risk of inattention or hyperactivity compared with controls. However, our study suggests an increased prevalence of inattention and hyperactivity among children with ScCMV. Differences in IQ were confirmed to have a confounding effect. Evaluation for attention-deficit/hyperactivity disorder may be warranted in this population.

Intelligence and Academic Achievement With Asymptomatic Congenital Cytomegalovirus Infection.

OBJECTIVES: To examine intelligence, language, and academic achievement through 18 years of age among children with congenital cytomegalovirus infection identified through hospital-based newborn screening who were asymptomatic at birth compared with uninfected infants. METHODS: We used growth curve modeling to analyze trends in IQ (full-scale, verbal, and nonverbal intelligence), receptive and expressive vocabulary, and academic achievement in math and reading. Separate models were fit for each outcome, modeling the change in overall scores with increasing age for patients with normal hearing (n = 78) or with sensorineural hearing loss (SNHL) diagnosed by 2 years of age (n = 11) and controls (n = 40). RESULTS: Patients with SNHL had full-scale intelligence and receptive vocabulary scores that were 7.0 and 13.1 points lower, respectively, compared with controls, but no significant differences were noted in these scores among patients with normal hearing and controls. No significant differences were noted in scores for verbal and nonverbal intelligence, expressive vocabulary, and academic achievement in math and reading among patients with normal hearing or with SNHL and controls. CONCLUSIONS: Infants with asymptomatic congenital cytomegalovirus infection identified through newborn screening with normal hearing by age 2 years do not appear to have differences in IQ, vocabulary or academic achievement scores during childhood, or adolescence compared with uninfected children.

Breakfast consumption has no effect on neuropsychological functioning in children: a repeated-measures clinical trial.

BACKGROUND: Although many studies have investigated the relation between breakfast consumption and various domains of cognitive functioning within children, some of the reported findings are inconsistent. OBJECTIVE: We sought to determine the short-term effects of a breakfast meal on the neuropsychological functioning of healthy school-aged children after an overnight fast. DESIGN: The study was conducted in a clinical research center with the use of a counterbalanced repeated-measures design among children who either consumed breakfast or were fasting. The administered neuropsychological tests included measures of attention, impulsivity, short-term memory, cognitive processing speed, and verbal learning. The sample consisted of children aged 8-10 y (n = 128), of whom 52% were female, 38% were African American, 31% were Hispanic, 28% were white, and 3% were of another race/ethnicity. RESULTS: There were no significant (P ≥ 0.004) differences between breakfast meal consumption and fasting for any of the neuropsychological measures administered. CONCLUSION: Breakfast consumption had no short-term effect on neuropsychological functioning in healthy school-aged children. This trial was registered at clinicaltrials.gov as NCT01943604.
