“…Few studies have examined the poor-rich gap in AF and its correlates in India ( Kanjilal et al, 2010 ; Karlsson et al, 2021 ; Khadse & Bansod, 2021 ; Kumar et al, 2015 ; Kumar & Paswan, 2021 ; Mokalla & Mendu, 2020 ; Mukhopadhyay & Chakraborty, 2020 ; Nguyen et al, 2021 ; Pathak & Singh, 2011 ; Shirisha et al, 2022 ; Singh et al, 2020 ; Subramanian et al, 2008 ; Subramanyam et al, 2010 ). However, the small number of studies exploring this issue are either outdated ( Kanjilal et al, 2010 ; Kumar et al, 2015 ; Pathak & Singh, 2011 ; Subramanian et al, 2008 ; Subramanyam et al, 2010 ) or haven't focused on identifying risk factors that contribute to the poor-rich gap in AF using data from all the states and regions of India ( Karlsson et al, 2021 ; Khadse & Bansod, 2021 ; Kumar & Paswan, 2021 ; Mokalla & Mendu, 2020 ; Mukhopadhyay & Chakraborty, 2020 ; Nguyen et al, 2021 ; Shirisha et al, 2022 ; Singh et al, 2020 ). One recent study ( Porwal et al, 2021 ) has documented the poor-rich gap in AF using the Comprehensive National Nutrition Survey (2016–18) data.…”
