Table 1 shows that children included in analyses did not differ
in the variables from the CCCEH children who were excluded from
the analysis due to missing data, except that they had a higher
proportion of African Americans and a slightly higher proportion
of common mouse sightings at both ages. Among those included,
37.7% reported cockroach sightings at least weekly at age 5 with a
lower rate at age 9 (19.3%) (McNemar test: po0.001). The prevalence
of cockroach sensitization was higher in boys than in girls
at both ages (19/87 [21.8%] vs. 14/101 [13.9%] at age 5 and 34/87
[39.1%] vs. 28/101 [27.7%]) while not statistically significant (χ2
test, psZ0.10).
