Epidemiology of Alcohol Use in Late Adolescence in Greece and Comorbidity with Depression and Other Common Mental Disorders.

BACKGROUND: The aim of the current study was to examine the prevalence and associations of hazardous alcohol use with sociodemographic variables and its comorbidity with depression and other common mental disorders in a sample of Greek adolescents between 16 and 18 year old. METHODS: We recruited 2431 adolescents attending 25 senior high schools in Greece. We assessed depressive and anxiety disorders using the computerized version of a fully-structured psychiatric interview (the revised Clinical Interview Schedule / CIS-R). Alcohol use was assessed using questions taken from a previous WHO school survey. RESULTS: Approximately one-third of adolescents (overall: 30.7%, boys: 39.2%, girls: 21.9%, p < 0.001) consumed alcohol on a weekly basis. The experience of excessive consumption, leading to drunkenness at least two or more times in their lifetime, was reported by 15.39% of the adolescents (19.42% for the boys and 11.24% for the girls, p < 0.001). Frequent alcohol consumption and drunkenness were strongly associated with the presence of depression, all other anxiety disorders except panic disorder, current smoking, and lifetime cannabis use, lower school performance, bad or fair relationship with parents, and increased health services use. CONCLUSION: Alcohol use is highly prevalent among Greek adolescents. Special attention for the development of more focused preventive strategies should be paid to adolescents suffering from depression or other common mental disorders.

Prevalence, comorbidity, quality of life and use of services of obsessive-compulsive disorder and subthreshold obsessive-compulsive symptoms in the general adult population of Greece.

Objective: We aimed to describe the epidemiology of obsessive-compulsive disorder (OCD) and related subthreshold symptoms in the general population of Greece and to assess the comorbidity, use of health services and impact on quality of life of these syndromes in the general population. Methods: This was a secondary analysis of the 2009-2010 general population Greek psychiatric morbidity survey (4902 participants living in private households, response rate 54%). Psychiatric disorders were assessed with the revised Clinical Interview Schedule (CIS-R). Quality of life was assessed with the EuroQoL EQ-5D. Results: 1.69% of the participants (95% confidence interval [CI]: 1.33%-2.05%) met criteria for current OCD while 2.79% met criteria for subthreshold obsessive-compulsive symptoms (95%CI: 2.33%-3.26%). In the adjusted analysis few sociodemographic associations remained statistically significant. Although the full-blown syndrome was more severe in terms of comorbidity and quality of life our results showed that even subthreshold obsessive-compulsive symptoms were associated with significant comorbidity and reductions in quality of life. Use of mental health services was small. Conclusions: OCD is an under-treated public health problem that needs more attention in Greece and elsewhere. Provision of specialised mental health services should be a priority for publicly funded national health systems. Keypoints OCD is common in the general population of Greece with few sociodemographic associations apart from subjective financial difficulties. The comorbidity pattern of the full-blown syndrome versus the subthreshold obsessive-compulsive symptoms is similar and differs in magnitude in the expected way. Quality of life in OCD is greatly reduced especially when there is chronicity and/or comorbidity with depression. Use of services is limited but comorbidity with depression may increase the chances of consultation with a mental health professional.

Epidemiology and comorbidity of obsessive-compulsive disorder in late adolescence: a cross-sectional study in senior high schools in Greece.

OBJECTIVE: The aim of this study was to examine the epidemiology, comorbidity and use of health services of obsessive-compulsive disorder (OCD) and subclinical obsessive-compulsive symptoms in late adolescence. METHODS: A total of 2427 adolescents attending senior high schools in Greece were selected for a detailed psychiatric interview using the revised clinical interview schedule (CIS-R). Use of alcohol, nicotine and cannabis, and several socio-demographic and socio-economic variables were also assessed. RESULTS: The prevalence of OCD was 1.39% (95% confidence interval [CI]: 1.05-1.84) while that of subclinical obsessive-compulsive symptoms was 2.77% (2.22-3.45). There was a female preponderance for subclinical symptoms. Financial difficulties of the family was the only socio-demographic variable that was significantly associated with OCD but not with subclinical symptoms. The pattern of comorbidity was similar for both conditions but milder in the subclinical form. About one in three reported use of general health services and one in ten use of psychiatric services. CONCLUSIONS: OCD and subclinical obsessive-compulsive symptoms were relatively common. Comorbidity with other psychiatric disorders and use of substances was considerable even in subclinical status, but use of specialised health services was small. Clinical and research implications are discussed.

The association between bullying-related behaviours and subjective health complaints in late adolescence: cross-sectional study in Greece.

BACKGROUND: Bullying is quite prevalent in the school setting and has been associated with several subjective health complaints such as headache, backache, abdominal pain, dizziness, fatigue and sleep problems. The aim of the present study was to investigate the association between bullying and subjective health complaints in a sample of Greek adolescents taking into account the presence of psychiatric morbidity. METHODS: A stratified random sample of 2427 adolescents aged 16-18 years old and attending senior high schools were randomly selected for a computerized interview. Subjective health complaints were assessed using a symptom checklist used in the context of a previous World Health Organization study and relevant sections of the revised Clinical Interview Schedule (CIS-R). The latter was also used for the assessment of psychiatric morbidity. Bullying was assessed with the revised Olweus bully/victim questionnaire. A series of logistic regression models were used to investigate the association between bullying and subjective health complaints. RESULTS: Victims of bullying were more likely to report backache (Odds Ratio [OR] = 1.92, 95% CI: 1.01-3.67), dizziness (OR = 2.83, 95% CI: 1.11-7.22) and fatigue (OR = 0.41, 95% CI: 0.19-0.86), independently of the presence of psychiatric morbidity. In addition bullying perpetrators were more likely to report backache (OR = 3.49, 95% CI: 1.49-8.18). It is worth noting that sleep problems and abdominal pain were also associated with being bullied and fatigue with bullying perpetration but these associations were all attenuated after adjustment for psychiatric morbidity. CONCLUSIONS: Strong associations between bullying in schools and subjective health complaints among a sample of Greek students aged 16-18 years have been observed. The exact nature of these associations should be investigated in future longitudinal studies.
