Abstract

Purpose

Sedentary behavior research typically only examines screen time activities and not communication time activities, such as talking on the phone, texting, or instant messaging.

Methods

Data from 2,449 grade 5 to 8 students were used to examine factors associated with the time youth spent in communication-based sedentary behaviors.

Results

Screen time, physical activity, grade, and gender were associated with moderate and high communication time.

Discussion

Future research on sedentary behavior should include measures of communication time.

Methods

This cross-sectional study used self-reported data collected from a convenience sample of 2,449 grade 5 to 8 students attending 30 elementary schools (Ontario, Canada) as part of the PLAY-On study. Additional details about PLAY-On are available online (www.shapes.uwaterloo.ca/projects/PLAYON). Using active consent procedure, eligible students completed the questionnaire during class time. The University of Waterloo and appropriate School Board Ethics committees approved the study procedures.

Results

Demographic characteristics are presented in Table 1. The study sample was 47.4% (n = 1,152) male and 52.6% (n = 1,277) female. The majority of students (63.6%) reported less than 1 hour of communication time per day; females were more likely than males to report more communication time per day (χ2 = 29.45, df = 2, p < .001). Students who reported high levels of communication time were also more likely to report high levels of screen time (χ2 = 331.98, df = 4, p < .001) and be in higher grades

Discussion

Developing a better understanding of SB is critical for increasing PA levels and preventing and reducing obesity among youth. The present study identified that many students are involved in communication-based SB (but to a slightly lesser extent than screen-based SB), and that the level of communication time is positively associated with screen time, PA, and grade. These elementary school data suggest that efforts to reduce SB should also include behaviors which are not screen-based and provide

  • Do school physical activity policies and programs have a role in decreasing multiple screen time behaviours among youth?

    Until now, most studies measuring ST have predominantly considered only TV and computer time, where computer time included both Internet surfing and video gaming (Mark et al., 2006; Atkin et al., 2014). It is important to not only segregate these individual ST behaviours, but also to account for communication-based ST behaviours such as texting, online messaging and emailing to capture the complete picture of youth ST accumulation in today's world (Leatherdale, 2010; Leatherdale & Harvey, 2015). In terms of interventions to minimize ST, PA plays a critical role because youth engagement in MVPA has not only been associated with lower total ST in youth, but also in the reduction in daily time available to engage in ST behaviours (Serrano-Sanchez et al., 2011; Fountaine et al., 2008).

    For example, several studies have reported positive relations between time spent using media and technology (i.e., television, computer use, cell phones, video games) and Body Mass Index (BMI) scores among children and adolescents. These studies have assumed that the use of media and technology promotes sedentary behavior and therefore, the time that one devotes to media and technology may contribute to increases in BMI among children and adolescents (Arora et al., 2013; Crawford, Jeffery, & French, 1999; Leatherdale, 2010; Proctor et al., 2003). Few studies have investigated the role that technology plays in BMI among young adults (see Kuhlmann, 2013; Mamun, O’Callaghan, Williams, & Najman, 2013).

    We also found a greater relationship between phone messaging and cravings for salty/fatty snacks and sweet snacks among Hispanic adolescents. Youths’ use of handheld communication devices has recently gained attention as a potentially problematic sedentary behavior.10 Time spent texting and messaging, for example, has recently increased substantially for adolescents in general and Latino adolescents in particular.35

    Gender transcendence was a negative predictor, F(1, 125) = 4.84, p = .03, adjusted r2 = .03, β = −.19, of vulgar abbreviation use in women. Even though previous research (Hofferth & Moon, 2012; Leatherdale, 2010; Lenhart, 2012; Rosen et al., 2010; Tossell et al., 2012) reported that females, compared to males, texted more frequently and used more emoticons, participant sex did not significantly predict these variables in this study. This may have been partially due to the relatively small number of males, compared to females, in our sample as well as possible greater male–female similarity in a college sample of students enrolled in a lifespan development class.
