Self-reported social anxiety symptoms and correlates in a clinical (CAP) and a community (Young-HUNT) adolescent sample

Purpose

The frequencies of social anxiety symptoms in a mental health clinical and a community sample of adolescents are compared. Also, we explore if adolescents can be classified in subgroups based on social anxiety symptoms. Associations between social anxiety symptoms and coexisting problems and sociodemographic characteristics are examined.

Methods

Adolescent participants, aged 13–18, in two large Norwegian studies, consisting of a clinical (n = 694, 42.1 % participation rate, 55 % girls, mean age = 15.6) and a community (n = 7,694, 73.1 % participation rate, 51 % girls, mean age = 15.8) sample completed identical self-report questionnaires measuring social anxiety and related variables.

Results

Median sum scores (interquartile range) of social anxiety symptoms were higher among girls than boys and in the clinical [girls = 16 (12–22); boys = 12 (9–16)] compared to the community sample [girls = 12 (9–15); boys = 10 (7–12)] (p < 0.001). Latent profile analysis revealed two classes of adolescents based on social anxiety profiles. Adolescents scoring high on social anxiety symptoms, which ranged from 16 % (boys in community sample) to 40 % (girls in clinical sample), had significantly more coexisting problems than those scoring low. Social anxiety symptoms were associated with academic school problems, bullying, eating problems, acne, and general anxiety and depression in both samples.

Conclusion

Social anxiety symptoms were commonly reported by adolescents, in both clinical and community settings. These symptoms were associated with a broad spectrum of coexisting problems, which can be used to detect adolescents struggling with social anxiety. Adolescent, family, peer, school, and community interventions targeting these associated problems may contribute to prevent and alleviate social anxiety symptoms.     

Correlates of depressive symptoms in urban middle-aged and elderly Lithuanians

Purpose

The study aimed to examine the prevalence of depressive symptoms and their correlates in urban middle-aged and elderly Lithuanian adults.

Methods

Data from the survey was collected within the framework of the international project HAPIEE (Health, Alcohol and Psychosocial Factors in Eastern Europe). A random sample of 7,115 individuals aged 45–72 years was screened in 2006–2008.

Results

Depressive symptoms were differently associated with independent variables by sex. In men, deprivation (OR 1.85, 95 % CI 1.54–2.17), being divorced (OR 2.34, 95 % CI 1.61–3.39) or widowed (OR 3.64, 95 % CI 2.40–5.52), physical inactivity (OR 1.30, 95 % CI 1.02–1.65), having a history of spine and joint disease (OR 1.72, 95 % CI 1.36–2.17), average perceived health (OR 2.14, 95 % CI 1.55–2.95), poor perceived health (OR 5.13, 95 % CI 3.39–7.76), average quality of life (OR 2.0, 95 % CI 1.55–2.95), or poor quality of life (OR 8.86, 95 % CI 5.19–15.13) were significantly associated with depressive symptoms. In women, deprivation (OR 1.28, 95 % CI 1.15–1.43), being widowed (OR 1.52, 95 % CI 1.23–1.88), mean dose of alcohol per occasion 40–79.9 g (OR 1.65, 95 % CI 1.18–2.30) and more than 80 g (OR 2.09, 95 % CI 1.14–3.82), physical inactivity in leisure time (OR 1.27, 95 % CI 1.04–1.57), having a history of spine and joint disease (OR 1.26, 95 % CI 1.06–1.51), average perceived health (OR 2.56, 95 % CI 1.89–2.72), poor perceived health (OR 5.07, 95 % CI 3.62–7.11), average quality of life (OR 2.27, 95 % CI 1.89–2.72), or poor quality of life (OR 7.21, 95 % CI 4.73–11.00) were significantly associated with depressive symptoms.

Conclusions

Health status and lifestyle factors are associated with depressive symptoms. Associations between depressive symptoms and long-term health problems are partially mediated by self-rated quality of life and self-rated health.     

Depressive symptoms among adolescents and older adults in Mexico City

Purpose

Determine the structure of depressive symptoms among adolescents and older adults through the person-centered approach of latent class analysis (LCA).

Methods

The study is based on data from two independent samples collected in Mexico City (2,444 adolescents and 2,223 older adults) which included the revised version of the CES-D. The presence or absence of depressed mood (dysphoria), diminished pleasure (anhedonia), drastic change in weight, sleep problems, thinking and concentration difficulties, excessive or inappropriate guilt, fatigue, psychomotor agitation/retardation, and suicide ideation were used in LCA to determine the structure of depressive symptoms for adolescents and older adults.

Results

Adolescents reported higher excessive or inappropriate guilt compared to older adults, while older adults had higher proportions of anhedonia, sleep problems, fatigue, and psychomotor agitation/retardation. Similar proportions were found in other symptoms. The LCA analysis showed the best fit with four latent classes (LC): LC 1, “symptoms suggestive of major depressive episode (MDE)” with prevalence of 5.9 % (n = 144) and 10.3 % (n = 230) among adolescents and older adults, respectively; LC 2, “probable MDE symptoms” 18.2 % (n = 446) and 23.0 % (n = 512); LC 3, “possible MDE” 27.7 % (n = 676) and 21.8 % (n = 485); LC 4, “without significant depressive symptoms” 48.2 % (n = 1,178) and 44.8 % (n = 996). The differences in item thresholds between the two groups (adolescents vs. older adults) were statistically significant (Wald test = 255.684, df = 1, p < 0.001).

Conclusions

This study documented important similarities and differences in the structure of depressive symptoms between adolescents and older adults that merit acknowledgment, further study, and consideration of their potential clinical and public health implications.     

Stress and Coping Predicts Adjustment and Glycemic Control in Adolescents with Type 1 Diabetes

Background

Adolescents with type 1 diabetes are at increased risk for deteriorating glycemic control, poor quality of life, and depressive symptoms. Stress and coping are related to these outcomes in adolescents with diabetes, yet few studies have examined these constructs longitudinally.

Purpose

This study aimed to describe stress and coping in adolescents with type 1 diabetes and to examine coping strategies as predictors of adolescent adjustment (i.e., depressive symptoms, quality of life) and glycemic control.

Methods

Adolescents with type 1 diabetes completed measures of diabetes-related stress, coping, symptoms of depression, and quality of life at baseline, 6 months, and 12 months. Data on glycemic control were collected from the adolescents’ medical charts.

Results

The adolescents’ use of primary control coping (e.g., problem solving) and secondary control engagement coping (e.g., positive thinking) strategies predicted significantly fewer problems with quality of life and fewer depressive symptoms over time. In contrast, the use of disengagement coping strategies (e.g., avoidance) predicted more problems with quality of life and depressive symptoms. Coping was not a significant predictor of glycemic control. Coping mediated the effects of diabetes-related stress on depressive symptoms and quality of life.

Conclusions

The ways in which adolescents with type 1 diabetes cope with diabetes-related stress predict quality of life and symptoms of depression but not glycemic control. Through the use of screening to identify adolescent’s diabetes-related stress and targeted interventions to improve coping strategies, there is potential to improve outcomes.

     

Exposure to violence in relation to depressive symptoms among male and female adolescent students in Cambodia

Purpose

In spite of the apparent increases in family and community violence, research into its effects on adolescent mental health has received limited attention in Cambodia. This study examines the association between exposure to violence and depressive symptoms among adolescents controlling for the effects of several factors in family and school domains.

Methods

We randomly selected 993 male and 950 female students proportionally from 11 junior high schools and high schools in Battembang provincial city. Students were questioned about the violence to which they were subjected and which they witnessed in their family and community. The Asian Adolescent Depression Scale was used to measure depressive symptoms.

Results

In this study, 27.9 % of male students and 21.5 % of female students had been victimized in at least one case of family violence, while 18.0 % of male and 5.8 % of female students had been victimized in at least one case of community violence. After adjustment, increased levels of depressive symptoms were significantly associated with being the victim of or witnessing family or community violence among both male and female students. However, the positive association between the levels of depressive symptoms and being a witness to community violence was found only in female students.

Conclusions

Efforts to prevent depression in adolescent students should focus on reducing family and community violence; such efforts should also consider gender differences.     

Early Adolescent Relationship Predictors of Emerging Adult Outcomes: Youth With and Without Type 1 Diabetes

Background

Emerging adulthood is a high-risk period for mental health problems and risk behaviors for youth generally and for physical health problems among those with type 1 diabetes.

Purpose

The purpose of this study was to examine whether adolescents’ relationships with parents and friends predict health and risk behaviors during emerging adulthood.

Method

Youth with and without diabetes were enrolled at average age 12 and followed for 7 years. Parent and friend relationship variables, measured during adolescence, were used to predict emerging adulthood outcomes: depression, risk behavior, and, for those with diabetes, diabetes outcomes.

Results

Parent relationship quality predicted decreased depressive symptoms and, for those with diabetes, decreased alcohol use. Parent control predicted increased smoking, reduced college attendance, and, for control participants, increased depressive symptoms. For those with diabetes, parent control predicted decreased depressive symptoms and better self-care. Friend relationship variables predicted few outcomes.

Conclusions

Adolescent parent relationships remain an important influence on emerging adults’ lives.     

The relationship between cognitive ability and depression: a longitudinal data analysis

Purpose

There is literature indicating cognitive ability and depression are related, but few studies have examined the direction of the relationship. This study examined the relationship between depression levels and cognitive abilities from adolescence to early adulthood.

Methods

Using the National Longitudinal Study of Adolescent Health (n = 14,322), this study used path modeling to investigate the relationship between depression and cognitive ability at baseline and again 8 years later.

Results

After controlling for initial levels of depression, cognitive ability, and other covariates, depressive symptoms in adolescence are related to cognitive ability in early adulthood, but adolescent cognitive ability is not related to adult depression levels. Moreover, after controlling for adolescent levels of depression and cognitive ability, the cognitive ability–depression relationship disappears in adulthood.

Conclusions

The cognitive ability–depression relationship appears early in life, and it is likely that the presence of depressive symptoms leads to lower cognitive ability. Thus, intervening at early signs of depression not only can help alleviate depression, but will likely have an effect of cognitive ability as well.     

Sub-syndromal depression in adolescents attending primary care: frequency, clinical features and 6 months outcome

Background

The nature of adolescent sub-syndromal depression has not been investigated in primary care.

Aims

To document frequency, characteristics and 6 month outcome of sub-syndromal depression amongst adolescent primary care attenders.

Method

Primary care attenders (13–18 years) completed depression screening questionnaires (Mood and Feelings Questionnaires) at consultation and at 6 month follow-up. Those screening positive were interviewed with the K-SADS. Sub-syndromal depression was defined as high levels of depressive symptoms in the absence of depressive disorder.

Results

Two hundred and seventy four questionnaires were completed at consultation: the estimated rate of sub-syndromal depression was 25 %. These young people were clinically intermediary between those without depressive symptoms and those with depressive disorder; at 6-months follow-up 57 % had persistent depressive symptoms and 12 % had developed a depressive disorder. Negative life events during the follow-up period and a positive family history of depression were the strongest predictors of symptom persistence and the development of depressive disorder, respectively.

Conclusion

Sub-syndromal depression is common and persistent, in adolescent primary care attenders and it deserves attention.     

Resilience, lifestyle and symptoms of anxiety and depression in adolescence: the Young-HUNT study

Purpose

This study investigated the symptoms of anxiety and depression in adolescence, their associations with lifestyle and resilience and the possibility that resilience factors can attenuate the associations between unhealthy lifestyle and symptoms of anxiety and depression.

Methods

Adolescents (n = 7,639) aged 13–18 years completed a questionnaire regarding lifestyle and health. Symptoms of anxiety and depression were measured by the SCL-5, a five-item shortened version of the Hopkins Symptom Checklist. Resilience factors included questions on friends and family relations and two sub-scales of the Resilience Scale for Adolescents; Family cohesion and Social competence.

Results

Of the total population, 13 % reported symptoms of anxiety and depression. Resilience characteristics were associated with lower symptom levels (ORs ranging from 0.2 to 0.6), and substance use and infrequent physical activity with higher symptom levels (ORs ranging from 2.1 to 4.0). The associations with substance use were strengthened by social competence, but attenuated by family cohesion. The association with physical activity was attenuated by both social competence and family cohesion.

Conclusion

Symptoms of anxiety and depression were frequent in adolescents and were associated with unhealthy lifestyle factors as substance use and low physical activity. Resilience characteristics seemed to protect against symptoms and markedly influenced the associations between lifestyle factors and symptoms of anxiety and depression. The importance of family and other supportive relationships should be emphasized in treatment and prevention of anxiety and depression in adolescence.     

Factors associated with the development of self-harm amongst a socio-economically deprived cohort of adolescents in Santiago,Chile

Purpose

Studies carried out in the West indicate that the incidence of self-harm (SH) is particularly high amongst adolescents, but few studies have investigated its incidence and aetiology in low-income countries. The purpose of this study was to investigate risk factors associated with new onset episodes of SH, amongst Chilean adolescents from low socio-economic backgrounds.

Methods

Prospective cohort study nested within a cluster randomised controlled trial. A 6-month follow-up for 2,042 adolescents, median age 14 years, from socio-economically deprived areas of Santiago, Chile.

Results

The lifetime prevalence of SH was 23 %. The incidence rate of SH at 6 months was 14 % amongst those reporting no SH at baseline. In multivariable analyses, risk factors for incident SH include depressive symptoms, suicidal thoughts, poor problem-solving skills and cannabis misuse.

Conclusions

The prevalence and incidence of SH in this socio-economically deprived sample differed highly according to gender. Poor problem-solving skills, suicidal thoughts, and cannabis misuse were associated with onset of SH.     

Neighborhood disadvantage in context: the influence of urbanicity on the association between neighborhood disadvantage and adolescent emotional disorders

Purpose

Inconsistent evidence of a relationship between neighborhood disadvantage and adolescent mental health may be, in part, attributable to heterogeneity based on urban or rural residence. Using the largest nationally representative survey of US adolescent mental health available, we estimated the association between neighborhood disadvantage and adolescent emotional disorders and the extent to which urbanicity modified this association.

Methods

The National Comorbidity Survey Replication Adolescent Supplement (NCS-A) sampled adolescents aged 13–17 years (N = 10,123). Households were geocoded to Census tracts. Using a propensity score approach that addresses bias from non-random selection of individuals into neighborhoods, logistic regression models were used to estimate the relative odds of having a DSM-IV emotional disorder (any past-year anxiety disorder, major depressive disorder or dysthymia) comparing similar adolescents living in disadvantaged versus non-disadvantaged neighborhoods in urban center, urban fringe, and non-urban areas.

Results

The association between neighborhood disadvantage and emotional disorder was more than twice as large for adolescents living in urban centers versus non-urban areas. In urban centers, living in a disadvantaged neighborhood was associated with 59 % (95 % confidence interval 25–103) increased adjusted odds of emotional disorder.

Conclusions

Urbanicity modifies the relationship between neighborhood disadvantage and emotional disorder in adolescents. This effect modification may explain why evidence of a relationship between neighborhood disadvantage and adolescent mental health has been inconsistent. Recognizing the joint influence of neighborhood socioeconomic context and urbanicity may improve specificity in identifying relevant neighborhood processes.     

Social inequalities in depression and suicidal ideation among older primary care patients

Purpose

Depression and suicide are major public health concerns, and are often unrecognized among the elderly. This study investigated social inequalities in depressive symptoms and suicidal ideation among older adults.

Methods

Data come from 1,226 participants in PROSPECT (Prevention of Suicide in Primary Care Elderly: Collaborative Trial), a large primary care-based intervention trial for late-life depression. Linear and logistic regressions were used to analyze depressive symptoms and suicidal ideation over the 2-year follow-up period.

Results

Mean Hamilton Depression Rating Scale (HDRS) scores were significantly higher among participants in financial strain [regression coefficient (b) = 1.78, 95 % confidence interval (CI) = 0.67–2.89] and with annual incomes below $20,000 (b = 1.67, CI = 0.34–3.00). Financial strain was also associated with a higher risk of suicidal ideation (odds ratio = 2.35, CI = 1.38–3.98).

Conclusions

There exist marked social inequalities in depressive symptoms and suicidal ideation among older adults attending primary care practices, the setting in which depression is most commonly treated. Our results justify continued efforts to understand the mechanisms generating such inequalities and to recognize and provide effective treatments for depression among high-risk populations.     

A survey of participants in two internet support groups for people with hair-pulling

Background

Coeliac disease in adolescents has been associated with an increased prevalence of depressive and disruptive behavioural disorders, particularly in the phase before diet treatment. We studied the possible effects of a gluten-free diet on psychiatric symptoms, on hormonal status (prolactin, thyroidal function) and on large neutral amino acid serum concentrations in adolescents with coeliac disease commencing a gluten-free diet.

Methods

Nine adolescents with celiac disease, aged 12 to 16 years, were assessed using the semi-structured K-SADS-Present and Lifetime Diagnostic interview and several symptom scales. Seven of them were followed at 1 to 2, 3, and 6 months on a gluten-free diet.

Results

Adolescent coeliac disease patients with depression had significantly lower pre-diet tryptophan/ competing amino-acid (CAA) ratios and free tryptophan concentrations, and significantly higher biopsy morning prolactin levels compared to those without depression. A significant decrease in psychiatric symptoms was found at 3 months on a gluten-free diet compared to patients' baseline condition, coinciding with significantly decreased coeliac disease activity and prolactin levels and with a significant increase in serum concentrations of CAAs.

Conclusion

Although our results of the amino acid analysis and prolactin levels in adolescents are only preliminary, they give support to previous findings on patients with coeliac disease, suggesting that serotonergic dysfunction due to impaired availability of tryptophan may play a role in vulnerability to depressive and behavioural disorders also among adolescents with untreated coeliac disease.     

Deliberate self-harm among adolescent psychiatric outpatients in Singapore: prevalence,nature and risk factors

Background

Deliberate self-harm (DSH) is a prominent mental health concern among adolescents. Few studies have examined adolescent DSH in non-Western countries. This study examines the prevalence, types and associated risk factors of DSH in a clinical sample of adolescents in Singapore.

Methods

Using a retrospective review of medical records, demographic and clinical data were obtained from 398 consecutive adolescent psychiatric outpatients (mean age?=?17.5?±?1.4 years, range?=?13–19 years) who presented at Changi General Hospital from 2013 to 2015.

Results

23.1% (n?=?92) of adolescents engaged in at least one type of DSH. Cutting was the most common type of DSH reported. Females were three times more likely to engage in DSH than males. DSH was positively associated with female gender (odds ratio [OR] 5.03), depressive disorders (OR 2.45), alcohol use (OR 3.49) and forensic history (OR 3.66), but not with smoking behaviour, living arrangement, parental marital status, past abuse or family history of psychiatric illness.

Conclusion

Interventions targeting adolescent DSH should also alleviate depressive symptoms, alcohol use and delinquent behaviours.

     

Pervasive refusal syndrome among inpatient asylum-seeking children and adolescents: a follow-up study

Background

Pervasive refusal syndrome (PRS) is a rare but severe condition, characterised by social withdrawal and a pervasive active refusal in terms of eating, mobilisation, speech and personal hygiene. PRS has been proposed as a new diagnostic entity in child and adolescent psychiatry, although the diagnostic criteria are debated. In the past 10 years there has been an increase in PRS symptoms among asylum-seeking children and adolescents in Sweden. Here, we describe five cases of PRS among asylum-seeking children and adolescents.

Method

Three females and 2 males, 7–17 years of age with the clinical picture of PRS, treated as inpatients at the Department of Child and Adolescent Psychiatry, Malmö, Sweden, 2002–2010, were analysed on the basis of their medical records. Subjects were diagnosed using previously suggested criteria for PRS. At follow-up, a semi-structured interview focusing on the inpatient stay and current status was performed. The subjects were assessed with Global Assessment of Functioning (GAF) and self-rating questionnaires regarding depression and post-traumatic stress disorder (PTSD).

Results

The pattern of refusal varied among the five subjects. All subjects originated from former Soviet republics, indicating a possible cultural factor. Mean period of inpatient treatment was 5 months. All subjects received intense nursing and were treated with nasogastric tube feeding. Parents were involved and were given support and instructions. All subjects gradually improved after receiving permanent residency permits. Depression and PTSD were co-morbid states. At follow-up, 1–8 years after discharge, all subjects were recovered.

Conclusion

Although a severe condition, our five cases suggest a good prognosis for PRS among asylum-seeking children and adolescents.     

Antenatal and postnatal maternal mental health as determinants of infant neurodevelopment at 18 months of age in a mother–child cohort (Rhea Study) in Crete, Greece

Purpose

A growing body of evidence links poor maternal mental health with negative outcomes on early child development. We examined the effect of antenatal and postnatal maternal mental health on infant neurodevelopment at age 18 months in a population-based mother–child cohort (Rhea Study) in Crete, Greece.

Methods

Self-reported measures of maternal depression (EPDS), trait anxiety (STAI-Trait) and personality traits (EPQ-R) were assessed in a sample of women during pregnancy and at 8 weeks postpartum (n = 223). An additional sample of 247 mothers also completed the EPDS scale at 8 weeks postpartum (n = 470). Neurodevelopment at 18 months was assessed with the use of Bayley Scales of Infant and Toddler Development (3rd edition).

Results

Multivariable linear regression models adjusted for confounders revealed that antenatal depressive symptoms (EPDS ≥ 13) were associated with decrease in cognitive development independently of postnatal depression. High trait anxiety and extraversion were associated with decrease and increase, respectively, in social–emotional development. Also, high trait anxiety and neuroticism had a positive effect on infants’ expressive communication. Finally, postpartum depressive symptoms (EPDS ≥ 13) were associated with decrease in cognitive and fine motor development independently of antenatal depression.

Conclusions

These findings suggest that antenatal and postnatal maternal psychological well-being has important consequences on early child neurodevelopment.     

Depressive symptoms in stroke patients treated and non-treated with intravenous thrombolytic therapy: a 1-year follow-up study

Introduction

This is a prospective study, first to compare the frequency of depressive symptoms in stroke survivors treated, and non-treated, with intravenous thrombolysis and second, to explore relationships between post-stroke depression (PSD) and stroke treatment modalities, taking into account other possible determinants of PSD, including post-traumatic stress symptoms.

Methods

Groups of 73 thrombolysed and 73 non-thrombolysed patients matched for age and gender were examined at 3 and 12 months after discharge. PSD was assessed using the Beck Depression Inventory. Post-traumatic stress symptoms (PTSS), disability and social support were assessed with the Impact of Event Scale-Revised, the Barthel Index and the Berlin Social Support Scale.

Results

At 3 months, PSD was present in 23.3% of the thrombolysed and 31.5% in the non-thrombolysed groups (p?=?0.265). At 12 months, the frequencies were 29.2 and 20.6% (p?=?0.229). Logistic regression of the combined group of thrombolysed and non-thrombolysed patients indicated that at 3 months, the adjusted predictors of PSD were disability (OR 24.35), presence of PTSS (OR 9.32), low social support (OR 3.68) and non-thrombolytic treatment (OR 3.19). At 12 months, the predictors were disability (OR 15.78) and low education (OR 3.61).

Limitations

The use of a questionnaire for the detection of depression, the relatively small sample size and a significant drop-out rate could limit the interpretation of these results.

Conclusions

(1) Thrombolysed and non-thrombolysed stroke survivors had similar frequency of depressive symptoms although the thrombolysed patients had more severe neurological deficits in the acute phase. It can be assumed that if thrombolysis had not been used, depressive symptoms would have been more frequent. (2) Lack of the rt-PA treatment was associated with three-time greater odds of screening for PSD at 3 months post-stroke, after adjustment for other PSD correlates. (3) Therefore, thrombolytic therapy seems to have a positive, but indirect, effect on patients’ mood, especially in the first months after stroke. (4) All stroke patients, irrespective of the method of treatment, should be monitored for the presence of depression.

     

Accuracy of Weight Perception Among Urban Early Adolescents with Uncontrolled Asthma and Their Caregivers

Background

Obesity is associated with poor asthma outcomes; weight loss improves such outcomes. Inaccurate recognition of obesity may impede weight control.

Purpose

We examined perception of weight by early adolescents with uncontrolled asthma and their caregivers, and tested the relationship between medical visit frequency and accuracy of perceived weight status.

Methods

A total of 373 adolescents and their caregivers reported the adolescent’s height/weight and weight perception; caregivers reported healthcare utilization. We measured height/weight. Logistic regression modeled accuracy of weight perception.

Results

A total of 43.7 % of the overweight/obese adolescents and caregivers accurately perceived weight status. BMI percentile [odds ratio (OR)?=?1.19, confidence interval (CI)?=?1.10–1.28] and total medical visits (OR?=?1.18, CI?=?1.05–1.33) were associated with higher accuracy in caregivers. Total medical visits (OR?=?0.84, CI?=?0.74–0.96) was associated with lower accuracy in adolescents.

Conclusions

Accurate perception of weight status was poor for overweight adolescents with uncontrolled asthma and their caregivers. Frequent medical visits were associated with improved caregivers’ but not adolescents’ perceptions.     

Diet quality and mental health problems in adolescents from East London: a prospective study

Purpose

In this study, we aimed to examine the relationship between diet quality and depression in a prospective study of adolescents from varied ethnic and cultural backgrounds.

Design

In this prospective cohort study, data were collected at two time points (2001 and 2003) from nearly 3,000 adolescents, aged either 11–12 years or 13–14 years, participating in RELACHS, a study of ethnically diverse and socially deprived young people from East London in the UK. Diet quality was measured from dietary questionnaires, and mental health assessed using the Strengths and Difficulties Questionnaire (SDQ) and the Short Mood and Feelings Questionnaire (SMFQ).

Results

In cross-sectional analyses, we found evidence for an association between an unhealthy diet and mental health problems. Compared to those in the lowest quintile of Unhealthy diet score, those in the highest quintile were more than twice as likely to be symptomatic on the SDQ (OR 2.10, 95 %CI 1.38–3.20) after taking all identified confounders into account. There was also some evidence for a cross-sectional inverse association between a measure of healthy diet and mental health problems. A prospective relationship between the highest quintiles of both Healthy (OR 0.63, 95 %CI 0.38–1.05) and Unhealthy (OR 1.75, 95 %CI 1.00–3.06) diet scores and SDQ scores at follow-up was also evident, but was attenuated by final adjustments for confounders.

Conclusion

This study is concordant with previous observational studies in describing relationships between measures of diet quality and mental health problems in adolescents.
