Children With Asthma: Asthma Control

Children With Asthma: Asthma ControlAsthma Control: The following four indicators of asthma control were analyzed on an exploratory basis (Table 2): reported activity limitations; symptom-free days (in the preceding 2 weeks); parental nocturnal awakening due to the child’s asthma (in the preceding 2 weeks); and lung function (ie, the percent predicted FEV1). The sample size is quite small for pulmonary function tests, since the younger children and, in this population, even some of the older children (with apparent developmental delays) were unable to correctly perform the test and, therefore, could not be tested. None of these measures showed a significant effect of the intervention, although baseline-adjusted group differences at 12 months for all measures except symptom-free days favored the intervention group. buy risnia 2 mg

Changes in Health-Care Utilization in Relation to Changes in Cotinine Level and Smoking Rules in the Home: Ideally (ie, assuming that the decrease in asthma health-care utilization was mediated entirely by a decrease in ETS exposure and that ETS exposures were measured without error), statistically controlling for the change in exposure should eliminate the significant association between the intervention and health-care utilization. However, this was not observed. The intervention effect on acute asthma visits remained when either of two covariates assessing exposure was included in the model. Prior to including the change in smoking restrictions in the model (n = 60 cases with follow-up interview data), the ORa was 0.20 (p = 0.01) and the ORu was 0.25 (p = 0.01). When the change in smoking restrictions was added, the ORs were essentially unchanged (ORa, 0.20 [p = 0.01]; ORu, 0.26 [p = 0.01]). Similarly, when the change in CCR was included (n = 51 cases with follow-up cotinine values), the results did not differ from those shown in line 2 of Table 3, which do not include the change in CCR in the model.
