Analysis of the multi-wavelength broadband photometry between rest-frame ultraviolet and near- infrared wavelengths indicates that the extinction corrected star-formation rates per unit stellar mass of a small sample of gamma-ray burst (GRB) host galaxies are higher than those of prototypical, nearby starbursts. This result, the confirmed detection of the host of GRB980703 at radio wavelengths, and the tentative evidence in favor of a supernova light curve underlying the visible light transient associated with some GRBs provides evidence for a connection between stellar phenomenon and GRBs. Fitting population synthesis models to the multiband photometry of the host galaxies reveals the presence of a young stellar population with age less than 50 Myr in 4 out of 6 galaxies, albeit with large uncertainties. Determining the age of the stellar population in a large number of GRB host galaxies using this technique could be one of the more reliable ways of distinguishing between the collapsar model for GRBs and models that involve the merger of degenerate objects in a binary system.
