Diagrammatic representation (pinwheel) of relation between affect, cognition and personality and excess gestational weight gain in systematic review of psychological antecedents of excess gestational weight gain. The results of the systematic review on the relation of affect, cognitions and personality with excess GWG are depicted in Figure 2. The major domains are positioned in the innermost circle. In the next circle, cognition is further divided into three sub-domains. These sub-domains are further divided to represent the individual exposures investigated. Boxes () have been used to represent adequately powered studies and diamonds () represent underpowered studies. The number within the boxes and diamonds corresponds to each study’s reference as listed in Tables 4, 5, 6 and 7. Boxes and diamonds are further coded as follows: Studies which performed multivariate analysis are shown with a thick border; studies which performed univariate analysis are shown with a thin border; Green = significant negative association (protective factor), red = significant positive association (risk factor) and yellow = non-significant association. Adjacent to the boxes and diamonds, symbols represent the following: = studies for which we were unable to determine power. * = significant only at subscale level of an exposure scale and △ = significant only at item level of an exposure scale. Exposures which were not investigated by any of the studies included in this systematic review are shown using crosshatching (). >: Greater than recommended target weight gain; <: Less than recommended target weight gain.
