The simultaneous multiple constraints of the IMF and SFR history based on the observed UBV R colours, Lyman continuum fluxes and chemical abundances Z resolve the IMF-SFR ambiguity in 100 extragalctic star formation complexes in 20 galaxies (SFCs). The separate study of SFCs with different SFR history shows links between IMF parameters and observed properties of SFCs as well as local and global properties of a host galaxy. The SFR history depends on the star density of SFCs. Low density regions demonstrate instantaneous starburst, while in high density SFCs extended star formation bursts are detected. Constrained IMF slopes are in a good agreement with direct observations of IMFs in OB associations of the Milky Way and LMC.
