Anxiety, depression and global distress among African American young adults with uncontrolled asthma.

BACKGROUND:Anxiety and depression are mental health disorders that are often comorbid with asthma. Urban African American young adults with asthma often experience increased risk of anxiety and depression. OBJECTIVE:To explore relationships between symptoms of psychological distress and asthma-related anxiety with asthma outcomes among urban African American young adults with poorly controlled persistent asthma. METHODS:A secondary analysis of baseline data from a larger study of 141 African American young adults with uncontrolled persistent asthma was examined. Participants completed the Brief Symptom Inventory (BSI-18), Youth Asthma-related Anxiety Scale, Asthma Control Test (ACT), a daily diary to assess asthma symptoms; and number of asthma attacks. Spirometry assessed airway obstruction. Generalized linear models tested associations. RESULTS:In multivariable models testing, higher somatization scores were significantly associated with lower ACT scores (adjusted β = -0.49; 95% CI = -0.69, -0.28; p < 0.01), and higher symptoms (adjusted β = 0.39; 95% CI = 0.14, 0.65; p < 0.01). After adding asthma-related anxiety to the model, the somatization subscale and asthma-related anxiety were significantly associated with ACT scores (adjusted β = -0.36; 95% CI = -0.57, -0.15; p < 0.01), (adjusted β = -0.32; 95% CI = -0.50, -0.14; p < 0.01), respectively. Asthma-related anxiety was also significantly associated with asthma attacks (adjusted β = 0.24; 95% CI = 0.05, 0.43; p < 0.05). CONCLUSION:This study suggests, asthma-related anxiety may differ from general anxiety and be related to poorly controlled asthma among African American young adults.
