Abstract

BACKGROUND:

Links between mental illness, self-inflicted injury and interpersonal violence are well recognised, but the association between poor mental health and unintentional injuries is not well understood.

METHODS:

We used the 2010 National Health Interview Survey to assess the association between psychological distress and unintentional non-occupational injuries among US adults. Psychological distress was measured by the Kessler Psychological Distress Scale, a symptom scale shown to identify community-dwelling persons with mental illness. Multivariable logistic regression was used to estimate adjusted ORs (AOR) and 95% CIs.

RESULTS:

Of the 26,776 individuals analysed, 2.5% reported a medically attended unintentional injury in the past 3 months. Those with moderate and severe psychological distress had 1.5 (1.2 to 1.8) and 2.0 (1.4 to 2.8) times higher odds of injury, respectively, as compared to those with low distress levels, after adjusting for age, sex, race, marital status, education level, alcohol use, physical functional limitation, medical comorbidity, employment status and health insurance status. Psychological distress was significantly associated with falls (AOR 1.4 (1.1 to 1.9)) and sprain/strain injuries (AOR 2.0 (1.5 to 2.8)), but not transportation-related injuries (AOR 1.2 (0.7 to 1.9)) or fractures (AOR 1.1 (0.8 to 1.6)).

CONCLUSIONS:

Among community-dwelling US adults, psychological distress is significantly associated with unintentional non-occupational injury, and the magnitude of association increases with severity of distress. The association between psychological distress and injury may be particularly strong for falls and sprain/strain injuries. These findings draw attention to a large group of at-risk individuals that may merit further targeted research, including longitudinal studies.
