Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Menopause01:28

Menopause

Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Disorders of the Male Reproductive System

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra. Symptoms...
Depressive Disorders: Etiology01:27

Depressive Disorders: Etiology

Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...
Depressive Disorders: MDD and Dysthymia01:27

Depressive Disorders: MDD and Dysthymia

Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...
Depression: Overview01:18

Depression: Overview

Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Area of Science:

  • Endocrinology
  • Gerontology
  • Psychiatry

Background:

  • Growing interest in the link between osteoporosis and depression in men.
  • Increased morbidity and mortality associated with coexisting conditions.

Purpose of the Study:

  • To evaluate the effect of major depression on bone density in middle-aged Greek men.
  • To compare bone mineral density (BMD) and osteoporosis incidence between depressed and non-depressed men.

Main Methods:

  • Retrospective study of 97 Caucasian men (mean age 65 years).
  • Bone mineral density (BMD) measured using dual-energy X-ray absorptiometry (DEXA) at the lumbar spine and/or femoral neck.
  • Men divided into two groups: with (Group A) and without (Group B) major depression.

Main Results:

  • Group A (depressed) showed a significantly higher incidence of osteoporosis (34.8%) and osteopenia (39.5%) compared to Group B (9.3% and 42.6%, respectively).
  • Mean BMD (0.876±0.170 vs 0.961±0.136, P=0.008) and T-score (-1.72±1.57 vs -1.06±1.17, P=0.02) were significantly lower in depressed men.
  • Major depression was associated with a 0.252 unit decrease in mean BMD and a 0.575 unit decrease in mean T-score (P<0.02).
  • Men with depression had nearly triple the relative risk (RR: 3.8, P=0.02) of developing osteoporosis.

Conclusions:

  • Significant differences in mean BMD and T-scores exist between depressed and non-depressed middle-aged men.
  • Major depression is an independent risk factor for reduced bone density and increased osteoporosis risk in men.
  • Further research is needed to clarify the interactive mechanisms between depression, sympathetic nervous system activation, aging, and bone resorption.
