Short-term impact of a randomized multifaceted intervention for wheezing infants in low-income families.

Objective: To present an interim analysis of the effect of a home-based intervention with low-income caregivers of wheezing infants at risk for childhood asthma on mediating variables.

Method: Infants aged 9 to 24 months with 3 or more physician-documented wheezing episodes were randomly assigned to environmental support intervention (ES) (n = 90) or control (n = 91) groups. Nurse home visitors intervened for 1 year to decrease allergen and environmental tobacco smoke exposure and improve symptom perception and management.

Etiology of the comorbidity between RD and ADHD: exploration of the non-random mating hypothesis.

The present research sought to test the validity of the non-random mating hypothesis in a community sample in order to determine whether it contributes significantly to the comorbidity between attention-deficit/hyperactivity disorder (ADHD) and reading disability (RD) and to test whether the two disorders segregate independently. Data were gathered from 394 twin participants of the Colorado Learning Disabilities Research Center (CLDRC) and their biological parents. Parents were asked to complete retrospective questionnaires regarding their own ADHD and RD symptomatology as children, as well as rate their children on DSM-IV ADHD symptomatology before age 12.
