Is usage of hypnotics associated with mortality?

Area of Science:

• Epidemiology
• Public Health
• Sleep Medicine

Background:

• Sleep disturbances and hypnotic medication use are prevalent in middle-aged populations.
• Understanding the long-term health consequences of hypnotic use is crucial for public health.
• Previous research has suggested potential links, but further investigation in well-defined cohorts is needed.

Purpose of the Study:

• To examine the association between regular hypnotic usage and all-cause mortality.
• To investigate the relationship between regular hypnotic usage and cause-specific mortality.
• To assess these risks in a middle-aged cohort over a 20-year period.

Main Methods:

• A cohort study involving 3523 men and women aged 30-65 years, recruited in 1983 via postal questionnaire.
• Data collected included hypnotic usage, sleep patterns, health status, depression, and lifestyle factors.
• Mortality data were tracked for 20 years (1983-2003), with cause-specific mortality analyzed.

Main Results:

• Regular hypnotic use was associated with short sleep, sleep difficulties, health problems, and depression.
• After adjusting for confounders, regular hypnotic use significantly increased all-cause mortality risk in both men (HR 4.54) and women (HR 2.03).
• In men, hypnotic use was a risk factor for death from coronary artery disease, cancer, suicide, and other causes. In women, it was a risk factor for suicide.

Conclusions:

• Regular hypnotic usage is associated with a significantly increased risk of all-cause mortality.
• Specific causes of death, including cardiovascular disease, cancer, and suicide, are also linked to regular hypnotic use.
• These findings highlight potential health risks associated with long-term hypnotic medication use.
