3.3.2. Centrality Indices

The central indices for all nodes in the network are shown in Figure 2. Anxious/depressed mood (overweight group: *z* = 2.76, underweight group: *z* = 2.47) and attention problems (overweight group: *z* = 1.14, underweight group: *z* = 1.18) were by far the nodes with the highest strength (named 'degree' in the centrality plot), thus representing the nodes with the highest overall influence in the network. These nodes also had the highest betweenness (anxious/depresses: *z* = 2.72/*z* = 2.16, attention problems: *z* = 1.53/*z* = 1.30) and closeness (anxious/depresses: *z* = 2.28/*z* = 1.48, attention problems: z = 1.76/*z* = 1.29), indicating that they also function as a bridge between other nodes of the network. For the underweight group, betweenness and closeness was also relatively high for the social problems (betweenness: *z* = 1.01, closeness: *z* = 0.98) and socially withdrawn (betweenness: *z* = 0.73, closeness: *z* = 1.09) nodes. The exact standardized centrality coefficients for all nodes (separated by the overweight and underweight groups) are provided in Supplementary Table S1.
