Prevalence and determinants of anxiety disorders among adolescents in a rural community from northern India

INTRODUCTION

There is scarce data available on community based prevalence of Anxiety Disorders (ADs) amongst adolescents in north Indian settings.

OBJECTIVE

To determine the prevalence of anxiety disorders, and associated factors amongst adolescents in a rural community of Ballabgarh block, district Faridabad, Haryana.

METHODS

Participants (10-19 years) were enrolled through simple random sequence from a sampling frame of adolescents residing in 28 villages of Ballabgarh block using household survey technique. They were screened using Screen for Childhood Anxiety Related Emotional Disorders (SCARED) tool and then subjected to confirmatory diagnosis using Mini-International Neuropsychiatric Interview for Children/Adolescent (MINI KID). All adolescents with ADs were assessed for co-psychiatric morbidities using MINI-KID and functional impairment using Children Global Assessment Scale (CGAS). Prevalence and 95% Confidence intervals are reported. Additionally, socio-demographic factors were elicited using a semi-structured interview schedule and associations were determined using multivariable logistic regression analysis.

RESULTS

A total of 678 adolescents participated in this study with mean age (SD) as 14.2 (2.5) years. The age adjusted prevalence of anxiety disorders was found to be 16.6% (95% CI: 16.0-17.2). The most prevalent anxiety disorder among participants was social anxiety disorders followed by specific phobias. Female sex and low socio-economic status were associated with anxiety disorders. Two third of adolescents with ADs had no functional impairment and almost one third were found to have one or more co-existing psychiatric co-morbidity.

CONCLUSION

We found a high prevalence of ADs in rural north Indian community settings warranting adequate health system response at primary care level.

Prevalence of DSM-5 anxiety disorders, comorbidity, and persistence of symptoms in Spanish early adolescents

Anxiety Disorders (AD) are the most prevalent mental disorders in children and adolescents and a relevant public health problem. The study aimed to determine the prevalence of ADs, the comorbidity, the sociodemographic correlates, and the functional impairment in Spanish school children. The initial sample included 1514 subjects (720 boys; mean age = 10.2), who filled out the Screen for Children's Anxiety-Related Emotional Disorders (SCARED). In a second phase, 562 subjects at risk and not-at-risk of anxiety were assessed with the Mini-International Neuropsychiatric Interview for Children and Adolescents to obtain DSM-5 diagnoses. Two years later (third phase; mean age 13.5), the SCARED was re-administered. The weighted prevalence of any AD was 11.8%. The most prevalent subtypes were specific phobia (16.2%) and generalized anxiety disorder (GAD) (6.9%). Girls showed higher rates of social anxiety (5.5%) than boys. Apart from being female, low socioeconomic status was also a risk factor for AD. The heterotypic comorbidity of any AD was 40.7%, and the homotypic comorbidity was 35.6%. After controlling for age and other ADs, we found that subjects with GAD had the highest risk of having other depressive disorders and ADs. Only 33.3% of the subjects with any AD had sought professional help. 52.9% of the subjects diagnosed with any of the ADs still had anxiety symptoms after a 2-year follow-up. These findings highlight that in Spain, ADs in early adolescence are an important public health problem and that detection and access to treatment need to be improved.

Neurodevelopmental disorders: prevalence and comorbidity in children referred to mental health services

BACKGROUND

Accurate prevalence rates of the neurodevelopmental disorders (ND) and comorbid conditions in child and adolescent mental health services (CAMHS) are essential for treatment planning and organization of health care. However, valid and reliable prevalence estimates from Nordic CAMHS populations are scarce, and the published findings vary.

AIMS

To report prevalence rates of ND (attention-deficit hyperactivity disorder: ADHD, tic disorder: TD or autism spectrum disorder: ASD) and comorbid disorders by a validated diagnostic instrument in children referred to CAMHS outpatient clinics.

METHODS

Parents of 407 consecutively referred children aged 7-13 years were interviewed with the semistructured interview schedule for affective disorders and schizophrenia, present and lifetime version (Kiddie-SADS-PL) at time of admittance.

RESULTS

One or more ND was diagnosed in 226 children (55.5%; 69.9% boys): ADHD (44.5%; 68.5% boys); TD (17.7%; 77.8% boys) and ASD (6.1%; 76% boys). Among children with ND 70 (31.0%) had only one ND with no comorbid disorder, 49 (21.7%) had more than one ND (homotypic comorbidity) and 131 (58%) had a non-ND psychiatric disorder (heterotypic comorbidity). Anxiety disorders were the most frequently occurring heterotypic comorbidity in all three ND. Comorbid depressive disorder was associated with older age, and comorbid anxiety disorder with female gender.

CONCLUSION

In children referred to CAMHS, ND constitute the most frequently occurring group of disorders, with high rates of both homotypic and heterotypic comorbidity. This needs to be taken into consideration in health service planning and treatment delivery.
