Suicide idea and depressive symptom in Korean adolescent with allergic disease

Cumulative evidence for association of rhinitis and depression

Background

Several primary studies evaluated the association between rhinitis and the incidence of depression and yielded inconsistent results. We conducted a meta-analysis of studies evaluating the association between rhinitis and depression.

Methods

We searched the EMBASE, PubMed and Cochrane Library databases for studies published in English before April 1, 2019. The studies were included if they reported any type of rhinitis in relation to depression. Two authors independently extracted the data. The odds ratios (ORs) were pooled using a random-effects model. Stratified analyses were conducted to evaluate the association.

Results

Among the 3472 initially identified studies, we included 14 studies involving a total of 19.36 ± 1.1 million participants according to predefined inclusion criteria. The associations between rhinitis (R), allergic rhinitis (AR), and nonallergic rhinitis (NAR) and depression were significant with ORs of 1.86 (95% CI 1.32 to 2.62, p < 0.05), 1.54 (95% CI 1.24 to 1.90, p < 0.05), and 2.15 (95% CI 1.49 to 3.09, p < 0.05), respectively. The results were consistent and statistically significant in all subgroup analyses.

Conclusions

Rhinitis was associated with an increased risk of depression. Further prospective studies involving large sample sizes are required to confirm the results by considering more confounders and clarify the mechanisms.

Association of atopic dermatitis with depression, anxiety, and suicidal ideation in children and adults: A systematic review and meta-analysis

BACKGROUND

Atopic dermatitis (AD) has been associated with anxiety and depression, but the magnitude of the alleged association is unknown.

OBJECTIVE

To perform a systematic review and meta-analysis of the association between AD in children and adults and, respectively, depression, anxiety, and suicidal behavior.

METHODS

The medical databases PubMed, Embase, and PsychINFO were searched.

RESULTS

There was a significant association between adult AD and, respectively, depression (pooled odds ratio [OR], 2.19; 95% confidence interval [CI], 1.87-2.57) and anxiety (pooled OR, 2.19; 95% CI, 1.75-2.73). AD was also associated with depression in children (pooled OR, 1.27; 95% CI, 1.12-1.45); few data were available for anxiety. A positive association was found between AD in adults and adolescents and suicidal ideation (pooled OR, 4.32; 95% CI, 1.93-9.66). Only a few studies examined the risk of completed suicide, but the majority showed a positive association between completed suicide and AD.

LIMITATIONS

Included studies used different definitions of depression and anxiety, and few studies examined the severity of AD.

CONCLUSION

Depression, anxiety, and suicidal ideation should be considered by doctors when treating patients with AD. Because AD disease improvement appears to reduce these risks, this should be a priority.
