Peru has experienced unprecedented mortality and economic toll due to the COVID-19 (Coronavirus disease 2019) pandemic in 2020. We aimed assess association between socioeconomic factors excess death rate, explore relative contribution of these differences rate during January-December 2020.Different national secondary data sources were used describe rates different determinants, from distal proximal. A confounding-adjusted multilevel mixed-effects linear regression was variables rates. Their contributions periods with highest lowest analyzed through regression-based Oaxaca-Blinder decomposition methods.The showed an increasing trend all regions, slopes. The analysis that higher healthcare access associated lower (difference (95%CI) -0.004 (-0.005, -0.002)), whereas incidence 0.052 (0.042, 0.063)). (41.9%), per capita income (19.4%) unemployment (14.6%) as main risk factors, while protective included health expenditure (44.7%), (33.2%) insurance (12.1%).Our study suggests may have been influenced by other besides incidence, proximal drivers, including outside within sector, susceptibility factors. Further studies at individual level are needed corroborate our findings.
