Impact of co-morbidities on self-rated health in self-reported COPD: an analysis of NHANES 2001-2008.

ABSTRACT: Chronic Obstructive Pulmonary Disease (COPD) coexists with co-morbidities. While co-morbidity has been associated with poorer health status, it is unclear which conditions have the greatest impact on self-rated health. We sought to determine which, and how much, specific co-morbid conditions impact on self-rated health in current and former smokers with self-reported COPD. Using the 2001-2008 National Health and Nutrition Examination Survey we characterized the association between thirteen co-morbidities and health status among individuals self-reporting COPD. Adjusted odds ratios (ORs) were generated using ordinal logistic regression. Additionally we evaluated the impact of increasing number of co-morbidities with self-rated health. Eight illnesses had significant associations with worse self-rated health, however after mutually adjusting for these conditions, congestive heart failure (OR 3.07, 95% CI 1.69-5.58), arthritis (OR 1.69, 95% CI 1.13-2.52), diabetes (OR 1.63, 95% CI 1.01-2.64), and incontinence/prostate disease (OR 1.63, 95% CI 1.01-2.62) remained independent predictors of self-rated health. Each increase in co-morbidities was associated with a 43% higher chance of worse self-rated health (95% CI 1.27-1.62). Individuals with COPD have a substantial burden of co-morbidity, which is associated with worse self-rated health. CHF, arthritis, diabetes and incontinence/prostate disease have the most impact on self-rated health. Targeting these co-morbidities in COPD may result in improved self-rated health.

Project description:BackgroundStudies on adults suggest that the presence of comorbid depression and Borderline Personality Disorder (BPD) is associated with an elevated risk of self-harming behaviours and that self-harming behaviours, when present, will have higher severity. This comorbidity, furthermore, complicates clinical assessments, which may be an obstacle to early identification and proper intervention. Adolescents who self-harm frequently report high levels of depressive symptoms, but this is often not reflected in the clinicians' assessment. BPD is still a controversial diagnosis in young people, and less is known about the clinical significance of comorbid BPD in adolescent populations.The purpose of the present study was to examine the impact of BPD on the assessment and course of self-reported and clinician-rated depression in self-harming adolescents before and after a treatment period of 19 weeks. We hypothesized that, compared to adolescents without BPD, adolescents with BPD would self-report higher levels of depression at baseline, and that they would have less reduction in depressive symptoms.MethodsA total of 39 adolescents with depressive disorders and BPD-traits participating in a randomised controlled trial on treatment of self-harm with Dialectical Behaviour Therapy adapted for Adolescents or enhanced usual care were included. Adolescents with full-syndrome BPD (n = 10) were compared with adolescents with sub-threshold BPD (n = 29) with respect to their self-reported and clinician-rated depressive symptoms, suicidal ideation and global level of functioning at baseline, and after 19 weeks of treatment (end of trial period).ResultsAt baseline, adolescents with full-syndrome BPD self-reported significantly higher levels of depressive symptoms and suicidal ideation compared to adolescents with sub-threshold BPD, whereas the two groups were rated as equally depressed by the clinicians. At trial completion, all participants had a significant reduction in suicidal ideation, however, adolescents with BPD had a poorer treatment outcome in terms of significantly higher levels of clinician-rated and self-reported depressive symptoms and significantly lower levels of global functioning. At baseline as well as at trial completion, self-reported and clinician-rated levels of depressive symptoms were not significantly correlated in adolescents with BPD. In a multiple linear regression analysis, a diagnosis of BPD and a high baseline level of clinician-rated depressive symptoms predicted higher levels of depressive symptoms at trial completion, whereas receiving Dialectical Behaviour Therapy predicted lower levels of depressive symptoms.ConclusionOur findings suggest that a diagnosis of BPD may have a strong impact on the assessment and course of depressive symptoms in self-harming adolescents. Although rated as equally depressed, adolescents with BPD self-reported significantly higher levels of depressive symptoms and suicidal ideation at baseline, and showed a poorer outcome in terms of higher levels of depressive symptoms and lower levels of global functioning at trial completion compared to adolescents with sub-threshold BPD. Our findings suggest that receiving Dialectical Behaviour Therapy could lead to a greater reduction in depressive symptoms, although firm conclusions cannot be drawn given the limited sample size.Clinicians should be aware of the possibility of underestimating the severity of depression in the context of emotional and behavioral dysregulation. Providing BPD specific treatments seems to be important to achieve sufficient treatment response with regard to depressive symptoms in adolescents with BPD-traits.Trial registrationTreatment for Adolescents With Deliberate Self Harm; NCT00675129, registered May 2008.

Project description:Feeding problems are an important area of neonatal morbidity that requires attention. We defined the feeding milestones related to transition to per oral feeding among premature infants based on gestational (GA) and postmenstrual ages (PMA), and elucidated the co-morbidity variables affecting with these skills.Feeding progress was tracked during the first hospitalization in a retrospective study involving 186 infants. We measured the age at acquisition of first feedings, maximum gavage feedings and maximum oral feedings. Resource usage measures included the total length of hospital stay (LOS), duration of gavage tube and duration of respiratory support. Effects of perinatal and co-morbidity factors on the acquisition of feeding milestones were evaluated. ANOVA, t-test, Wilcoxon rank sum test, chi(2) test, univariate and multivariate analysis, stepwise linear regression analysis and logistic regression analysis were applied as appropriate. Data were presented as mean+/-s.d., or as stated. P<0.05 was considered significant.We stratified the data into three groups based on GA at birth: <28.0 weeks (group-1), 28.0 to 32.0 weeks (group-2) and 32.0 to 35.0 weeks (group-3). Compared with group-3, group-1 needed four-fold more ventilation and five-fold more continuous positive airway pressure (CPAP) duration (all P<0.001); whereas group-2 needed two-fold more CPAP duration. Age at first feed correlated with age at full gavage feedings and age at full oral feedings (r=0.53 and r=0.71, both P<0.0001). Age at full gavage feedings correlated with age at full oral feedings (r=0.81, P<0.0001). Univariate analysis was significant for GA age, hypotension, the effects of gastroesophageal reflux, and duration of ventilation and CPAP on the PMA at maximal oral feedings (all P<0.05); multivariate analysis for these variables was also significant (R (2)=0.58, P<0.0001). The success rate for oral feedings at discharge accelerated with GA maturation and caffeine use; on the other hand, the need for respiratory support and management of positive blood culture were associated with failure rates (P<0.05).Infants < 28 weeks GA have significant feeding delays with respect to initiation and progression to maximal gavage and oral feedings, as well as prolonged LOS. Infants >28 weeks GA attained successful feeding milestones by similar PMA. Specific aero-digestive co-morbidities significantly affected maximal oral feeding milestone. Delays in achieving maximum gavage and maximum oral feeding milestones suggest delays with the development of control and regulation of foregut motility.
