Using cross-sectional design, an internet-based questionnaire was used to collect self-reported measures of daily mobile hand-held device use and self-reported symptoms of pain in the upper extremity, upper back, and neck in 140 students, faculty and staff at a Canadian university. A dichotomous exposure variable (low/high) was created for each of the six measures of mobile device use collected in the questionnaire as well as for total device use. Pain data collected in the questionnaire was dichotomized to "no pain"; (0 on Likert scale) or "any pain"; (1 to 10 Likert scale). By controlling for covariates (daily computer/laptop keyboard and mouse use, daily game controller use, UW status [faculty, staff or student] and gender) multivariate logistic regression was used to examine the relationship between the seven dichotomous mobile device use exposure variables and 24 dichotomous outcomes.
