A qualitative exploration of depression in emerging adulthood: disorder, development, and social context

Gluteal adipose-tissue polyunsaturated fatty-acids profiles and depressive symptoms in obese adults with obstructive sleep apnea hypopnea syndrome: a cross-sectional study

Biomarkers of Polyunsaturated Fatty Acids (PUFAs) have been related to depressive symptoms in healthy adults. It is also known that depression is high prevalent in Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) and obesity. The aim of our study was to examine a possible association between PUFAs of the n-6 and n-3 families and depressive symptoms in obese OSAHS patients. Sixty three patients with OSAHS based on overnight attended polysomnography were included. Gluteal adipose tissue biopsies were performed in all participants. Fatty acids were analyzed by gas chromatography. Depressive symptoms were assessed by the Zung Self-rating Depression Scale. The majority of participants had grade II obesity (BMI: 36.2±4.3 kg/m(2)) and moderate to severe OSAHS. Mild depressive symptoms were found to affect 27.8% of the studied patients. No link between symptoms of depression and individual n-6 and/or n-3 PUFAs of gluteal adipose tissue was detected. However, multiple linear regression analysis showed a positive correlation between depressive symptoms and 20:3n-6/18:3n-6 ratio, and a negative association with age and n-6/n-3 ratio. The possible influence of OSAHS and obesity in depression development and the quiescent nature of gluteal adipose tissue may account for the absence of any significant relations between n-6 and/or n-3 PUFAs and depressive symptoms in our sample. The positive relationship between symptoms of depression and the particular fatty acid ratio probably indicates an increase in prostaglandins family although this needs further research.

Adolescents with depressive symptoms and their challenges with learning in school

We examine school performance among 83 adolescents at risk for major depression. Negative mood interfered with subjective measures of school performance, including ability to do well in school, homework completion, concentrate in class, interact with peers, and going to class. No significant relationships were found for mood and objective measures of school performance (school attendance, English, and Math grades). Students with a college-educated parent had stronger performance in objective measures (school attendance and Math grades), whereas males had lower English grades. In qualitative interviews, adolescents reported that negative thinking led to procrastination, which led to poor school performance, which led to more negative thinking. Adolescents with depressive symptoms that do not meet the threshold for referral report struggles in school. Understanding the specific challenges faced by adolescents with even low levels of depressive symptoms can help school nurses, teachers, and parents identify appropriate interventions to help adolescents succeed in school.

Differences in vulnerability factors for depressive episodes in African American and European American adolescents

BACKGROUND

Although intervention tailoring could lower the burden of adolescent depression, few studies have examined differences in vulnerability factors between African American and European American youth.

METHODS

We determined and compared the prevalence, relative risk, and population-attributable risk (PAR) of baseline vulnerability factors predicting depressive episodes at 1-year follow-up in a nationally representative sample of African American and European American adolescents.

RESULTS

The leading (highest PAR) vulnerability factors for African American adolescents were demographics, while the top vulnerability factors for European American youth were current depressed affect and low perceived family connectedness. Unique vulnerability factors for African American youth were (1) neither parent finished high school, (2) believing oneself unintelligent, and (3) running away from home. Avoidant problem solving, divorce, poor residential father relationship, sexual relationships, and delinquent behaviors did not predict depressive episodes in African American adolescents but did in European American. Low family and peer connectedness were important common vulnerability factors for both groups.

CONCLUSIONS

Differing patterns of vulnerability suggest that alternative strategies may be better suited to preventing depression among African American youth. A first step may lie in understanding what mediates the effect of low parental educational status on future depression risk.

Adolescents in Primary Care with Sub-Threshold Depressed Mood Screened for Participation in a Depression Prevention Study: Co-Morbidity and Factors Associated with Depressive Symptoms

PURPOSE

Adolescents in primary care with sub-threshold depression symptoms may be candidates for early intervention to prevent onset of full major depressive disorder. Little is known about this population.

METHOD

We screened consecutive adolescents (ages 14-21) in 13 primary care sites for presence of depression symptoms for "at least a few days" or "nearly every day" in the last two weeks for possible enrollment in a primary care/Internet-based depression prevention intervention (CATCH-IT). We report illness severity, prevalence of self-harm ideation, prevalence correlates (automatic negative thoughts, generalized self-efficacy, perceived social support from family and friends) and co-occurring symptoms of other mental disorders with depressed mood.

RESULTS

Twenty-one percent (N=293) of those screened reported a core symptom of depressive disorder of which 83 enrolled in the study and were analyzed. The sample was 40% ethnic minority with a mean zip code household income of $40,249 (SD=$14,500). Reporting at least one symptom of another mental disorder was common for anxiety (48%, N=40), substance abuse (31%, N=15), conduct disorder (71%, N=53), as were self-harm ideation (16%, N=12) and reporting school impairment (100%, N=83). Prevalence correlates for current depressive symptoms included low self-efficacy, automatic negative thoughts, perceived low peer acceptance, and school impairment.

CONCLUSIONS

Adolescents with sub-threshold depressed mood have frequent co-morbid symptoms that may need to be considered in developing prevention interventions. Early intervention targets to reduce depressed mood include pessimistic thinking, low self-efficacy, low peer acceptance, and school impairment.

Perceived barriers to treatment for adolescent depression

BACKGROUND AND OBJECTIVE

Adolescent depression is common, disabling, and is associated with academic, social, behavioral, and health consequences. Despite the availability of evidence-based depression care, few teens receive it, even when recognized by primary care clinicians. Perceived barriers such as teen worry about what others think or parent concerns about cost and access to care may contribute to low rates of care. We sought to better understand perceived barriers and their impact on service use.

DESIGN

After completing an eligibility and diagnostic telephone interview, all depressed teens and a matched sample of nondepressed teens recruited from 7 primary care practices were enrolled and completed telephone interviews at baseline and 6 months (August 2005-September 2006).

PARTICIPANTS

Three hundred sixty-eight adolescent patients aged 13 to 17 (184 depressed and 184 nondepressed) and 338 of their parents.

MEASURES

Perceived barriers to depression care and use of services for depression (psychotherapy and antidepressant medication).

RESULTS

Teens with depression were significantly more likely to perceive barriers to care compared with nondepressed teens. Parents were less likely to report barriers than their teens; perceived stigma and concern about family member response were among the significant teen barriers. Teen perceived barriers scores were negatively associated with any use of antidepressants (P < 0.01), use of antidepressants for at least 1 month (P < 0.001), and any psychotherapy or antidepressant use (P < 0.05) at 6 months.

CONCLUSIONS

To improve treatment for adolescent depression, interventions should address both teen and parent perceived barriers and primary care clinicians should elicit information from both adolescents and their parents.

Integrative internet-based depression prevention for adolescents: a randomized clinical trial in primary care for vulnerability and protective factors

BACKGROUND

Adolescent depression is both a major public health and clinical problem, yet primary care physicians have limited intervention options. We developed two versions of an Internet-based behavioral intervention to prevent the onset of major depression and compared them in a randomized clinical trial in 13 US primary care practices.

METHODS

We enrolled 84 adolescents at risk for developing major depression and randomly assigned them to two groups: brief advice (BA; 1-2 minutes) + Internet program versus motivational interview (MI; 5-15 minutes) + Internet program. We compared pre/post changes and between group differences for protective and vulnerability factors (individual, family, school and peer).

RESULTS

Compared with pre-study values, both groups demonstrated declines in depressed mood; [MI: 21.2 to 16.74 (p < 0.01), BA: 23.34 to 16.92 (p < 0.001)]. Similarly, both groups demonstrated increases in social support by peers [MI: 8.6 to 12.1 (p = 0.002), BA: 7.10 to 12.5 (p < 0.001)] and reductions in depression related impairment in school [MI: 2.26 to 1.76 (p = 0.06), BA: 2.16 to 1.93 (p = 0.07)].

CONCLUSIONS

Two forms of a primary care/Internet-based behavioral intervention to prevent adolescent depression may lower depressed mood and strengthen some protective factors for depression.
