“…Previous studies have been limited by cross-sectional design (e.g., Bauman et al, 2012; Bray & Born, 2004), examining only one gender (e.g., Stetson et al, 1997), or have presented mixed findings (Allender, Foster, & Boxer, 2008; Feng et al, 2016). Additional study limitations include small sample sizes (Bray & Born, 2004; Butler et al, 2004) and nonrepresentative samples (Grimby et al, 2008; Li et al, 2016). These limitations point to the need for further research that includes the use of a longitudinal design with a nationally representative sample.…”
