Depressive symptoms are associated with lower bone mineral density in young adults with high job strain. The Cardiovascular Risk in Young Finns Study

Evaluation of the effect of long-term use of antidepressants in the SSRI group on bone density with dental volumetric tomography

Aim

The present study aims to employ dental volumetric tomography to examine bone mineral density among men that used antidepressants in the SSRI group for a long time.

Method

The present study was conducted through the utilisation of data related to patients that presented to the Faculty of Dentistry of Dicle University and had a dental volumetric tomography (DVT) scan for any reason. The patients were divided into 2 groups based on the use of antidepressants: Group 1 included 68 patients as the control group, and Group 2 consisted of 68 patients that used antidepressants. Radiomorphometric measurements were performed on DVT data: DVT-Mandibular Index (DVT-MI), DVT-Cortical Index (DVT-CI), Hounsfıeld Unit (HU) CORTICAL, and HU SPONGIOSIS values were calculated.

Results

The group of patients that used antidepressants exhibited a significant increase in DVT CI and a significant decrease in HU CORTICAL, HU SPONGIOSIS and DVT MI values. These findings were suggestive of osteoporosis.

Conclusion

Long-term use of antidepressants should be taken into consideration as a risk factor for osteoporosis in men.

The co-occurrence between depressive symptoms and paranoid ideation: A population-based longitudinal study

BACKGROUND

The aim of this study was to examine longitudinally in the general population (a) whether depressive symptoms co-occur with paranoid ideation from late adolescence to middle age (b) whether depressive subsymptoms are differently linked with paranoid ideation (c) whether depressive symptoms are associated with state-level or trait-level paranoid ideation.

METHODS

Altogether 2109 subjects of the Young Finns study completed the Paranoid Ideation Scale of the Symptom Checklist-90 Revised and a modified version of the Beck Depression Inventory in 1992, 1997, 2001, 2007, and 2012, and the Beck Depression Inventory-II in 2007, 2011, and 2012.

RESULTS

Higher self-rated depressive symptoms were associated with the course of more severe paranoid ideation over age, especially in late adolescence and early adulthood. Regarding depressive subsymptoms, the associations of negative attitude and performance difficulties with paranoid ideation were evident over age, whereas the influence of somatic symptoms (such as changes in sleep and appetite) was not significant until after early adulthood. Additionally, depressive symptoms were more evidently associated with the development of trait- than state-level paranoid ideation.

LIMITATIONS

Our study mostly captured mild depressive and paranoid symptoms. The results cannot be directly generalized to clinical populations.

CONCLUSIONS

Depressive symptoms were associated with the course of paranoid ideation from late adolescence to middle age. Patients with paranoid ideation might merit from evaluation of potential depressive symptoms, especially in late adolescence and early adulthood. Among patients with co-occurring depressive symptoms and paranoid ideation, there may be a substantial need for neurocognitive rehabilitation and community-based treatments.

Vitamin D Status, Bone Mineral Density and Mental Health in Young Australian Women: The Safe-D Study

Background.

Vitamin D deficiency has been associated with both poor bone health and mental ill-health. More recently, a number of studies have found individuals with depressive symptoms tend to have reduced bone mineral density. To explore the interrelationships between vitamin D status, bone mineral density and mental-ill health we are assessing a range of clinical, behavioural and lifestyle factors in young women (Part A of the Safe-D study).

Design and methods.

Part A of the Safe-D study is a cross-sectional study aiming to recruit 468 young females aged 16-25 years living in Victoria, Australia, through Facebook advertising. Participants are required to complete an extensive, online questionnaire, wear an ultra-violet dosimeter for 14 consecutive days and attend a study site visit. Outcome measures include areal bone mineral measures at the lumbar spine, total hip and whole body, as well as soft tissue composition using dual energy x-ray absorptiometry. Trabecular and cortical volumetric bone density at the tibia is measured using peripheral quantitative computed tomography. Other tests include serum 25-hydroxyvitamin D, serum biochemistry and a range of health markers. Details of mood disorder/s and depressive and anxiety symptoms are obtained by self-report. Cutaneous melanin density is measured by spectrophotometry.

Expected impact.

The findings of this cross-sectional study will have implications for health promotion in young women and for clinical care of those with vitamin D deficiency and/or mental ill-health. Optimising both vitamin D status and mental health may protect against poor bone health and fractures in later life.
