Cell Phones Bum Us Out

A new study correlates higher use of mobile phones with depression and sleep disturbances in young adults.

Background: Because of the quick development and widespread use of mobile phones, and their vast effect on communication and interactions, it is important to study possible negative health effects of mobile phone exposure. The overall aim of this study was to investigate whether there are associations between psychosocial aspects of mobile phone use and mental health symptoms in a prospective cohort of young adults.

Methods: The study group consisted of young adults 20–24 years old (n = 4156), who responded to a questionnaire at baseline and 1-year follow-up. Mobile phone exposure variables included frequency of use, but also more qualitative variables: demands on availability, perceived stressfulness of accessibility, being awakened at night by the mobile phone, and personal overuse of the mobile phone. Mental health outcomes included current stress, sleep disorders, and symptoms of depression. Prevalence ratios (PRs) were calculated for cross-sectional and prospective associations between exposure variables and mental health outcomes for men and women separately.

Results: There were cross-sectional associations between high compared to low mobile phone use and stress, sleep disturbances, and symptoms of depression for the men and women. When excluding respondents reporting mental health symptoms at baseline, high mobile phone use was associated with sleep disturbances and symptoms of depression for the men and symptoms of depression for the women at 1-year follow-up. All qualitative variables had cross-sectional associations with mental health outcomes. In prospective analysis, overuse was associated with stress and sleep disturbances for women, and high accessibility stress was associated with stress, sleep disturbances, and symptoms of depression for both men and women.

Conclusions: High frequency of mobile phone use at baseline was a risk factor for mental health outcomes at 1-year follow-up among the young adults. The risk for reporting mental health symptoms at follow-up was greatest among those who had perceived accessibility via mobile phones to be stressful. Public health prevention strategies focusing on attitudes could include information and advice, helping young adults to set limits for their own and others' accessibility.

Correlation != causation! Notice that the people who believe cell phones stress them out were the most likely to report being stressed out... I'm not saying I think cell phones don't stress us out, just that I'm skeptical of studies :)

correlation =//= causation
I hear you. Seems to me that people who sleep with their cell phones are more likely to be awakened by them, and who sleeps with their cell phone? Well I do, now that I have a jealous lover, and he disturbs my sleep even from far away, which could have the cumulative effect of running me down and bumming me out...and then there's the social isolation component. People who don't have dear ones close by are likely to spend more time on the phone....so people who talk on the cell phone more are more socially isolated? Because we know that isolation-->depression... And then there's the new finding that cell phones increase the glucose metabolism of the brain where the signal hits, and possibly inflammation there too....which would be a direct cause....So it's the chicken and egg question, combined with a high probability of nearly infinite multicausality where depression is concerned. And I agree, correlation EQUALS NOT causation.
