Objectives: This study aimed to estimate the trends in the prevalence and treatment of depressive symptoms using nationally representative surveys in Peru from 2014-2018.Design:A secondary analysis was conductedusing five nationally representative surveys carried out consecutively in the years between 2014and 2018, including a total of 166,290 individuals. Setting:The study was conducted in Peru.Participants:Individuals, men and women, aged≥15 years who participatedin the selected surveys. Sampling was probabilistic using a two-stage approach.Main outcome measures:Two versions of the Patient Health Questionnaire (PHQ-9)that focused on the presence of depressive symptomswere administered(one in the last two-week and other in the last-year). Scores ≥15 were used as the cut-off point in both versions of the PHQ-9to define the presence of depressive symptoms. Also, the treatment rate was based on the proportion of individuals who had experienceddepressive symptoms in the last-yearandwho had self-reported having received specific treatment for these symptoms.The age-standardized prevalence was estimated.Results:A total of 161,061 participants were included. There was no evidence of a change in age-standardized prevalence rates of depressive symptoms at the two weeksprior to the point of data collection(2.6% in 2014 to 2.3% in 2018), or in the last-year (6.3% in2014 to 6.2% in 2018).Furthermore,no change was found in the proportion of depressive cases treated in the last-year(14.6% in 2014 to 14.4% in 2018). Rural areas and individuals with low-level of wealth had lower proportion of depressive cases treated.Conclusions:No changes in trends of rates of depressive symptoms or in the proportion of depressive cases treated were observed. This suggests the need to reduce the treatment gap considering social determinants associated with inequality in access to adequate therapy.
