Association between smartphone use, sleep deprivation, and self-rated health outcomes: A retrospective observational survey in rural Japan.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Smartphone use significantly changes the lives of individuals. This study aimed to stratify sleep time by age and sex, examine the association between smartphone overuse and sleep deprivation, and measure their impact on self-rated health (SRH) outcomes. Focusing on communication and overuse, we also considered the association of active and passive smartphone use, as well as browsing, with sleep. Methods: We conducted a questionnaire survey among residents of three towns in rural Japan to collect data on the sleeping hours, smartphone ownership rate, and smartphone usage time of residents, stratified according to sex and age. Logistic regression analysis was conducted to investigate the association among good SRH outcomes, sleep deprivation, and smartphone overuse. Results: Among 2565 respondents to our questionnaire who possessed a smartphone (ownership 69.7%), 1172 men and 1393 women were analyzed. The mean age and sleep hours were 59.1 years and 6.7 h. Sleep time was shorter in middle-aged residents, and sex differences disappeared at younger ages. A total of 1295 participants experienced sleep deprivation. The smartphone overuse group comprised 627 participants. Good SRH outcomes were negatively associated with smartphone overuse and sleep deprivation. The group that used their smartphones for more than 1 h slept approximately 0.12-0.13 h less than the other group. Active/passive use and screen time were associated with good SRH outcomes. Conclusion: Avoiding sleep deprivation and smartphone overuse are activities that are useful for good SRH outcomes. Smartphone use with a clear purpose may not be antagonistic to good SRH outcomes.
