Summary, in English

BACKGROUND: Drug use Disorder (DUD), the risk for which is substantially influenced by both genetic and social factors, is geographically concentrated in high-risk regions. An important step toward understanding this pattern is to examine geographical distributions of the genetic liability to DUD and a key demographic risk factor - social deprivation.

METHODS: We calculated the mean family genetic risk score (FGRS) for DUD ((FGRS DUD) and social deprivation for each of the 5983 areas Demographic Statistical Areas (DeSO) for all of Sweden and used geospatial techniques to analyze and map these factors.

RESULTS: Using 2018 data, substantial spatial heterogeneity was seen in the distribution of the genetic risk for DUD in Sweden as a whole and in its three major urban centers which was confirmed by hot-spot analyses. Across DeSOs, FGRS DUD and s.d. levels were substantially but imperfectly correlated ( r = + 0.63), with more scattering at higher FGRS DUD and s.d. scores. Joint mapping across DeSOs for FGRS DUD and s.d. revealed a diversity of patterns across Sweden. The stability of the distributions of FGRS DUD and s.d. in DeSOs within Sweden over the years 2012-2018 was quite high.

CONCLUSIONS: The geographical distribution of the genetic risk to DUD is quite variable in Sweden. DeSO levels of s.d. and FRGS DUD were substantially correlated but also disassociated in a number of regions. The observed patterns were largely consistent with known trends in the human geography of Sweden. This effort lays the groundwork for further studies of the sources of geographic variation in rates of DUD.
