“…The methods of eight studies, including three quantitative and five qualitative studies, centred on the importance of examining the relationship between food insecurity and other factors longitudinally (Alley et al, 2009;Bhargava & Lee, 2016;Bhargava, Lee, Jain, Johnson, & Brown, 2012;Fitzpatrick et al, 2015;Frongillo et al, 2003;Green-LaPierre et al, 2012;Russell, Flood, Yeatman Wang, & Mitchell, 2016;Sattler & Lee, 2013;Sharkey, 2005). Other studies made use of cross-sectional data, while citing the importance of understanding the direction and the dynamics of the relationship between food insecurity and aging (Bengle et al, 2010;Brewer et al, 2010;Goldberg & Mawn, 2014;Klesges et al, 2001;Sharkey, 2004;Sharkey, 2005;Temple, 2006).…”
