Abstract

This study describes the time trend of suicide mortality rates in Teresina, 1996-2017. The data were obtained through SIM and IBGE, available in DATASUS. Suicide mortality rates were calculated according to sex and age groups. For assessing trends, the Prais-Winsten regression model was considered. 1033 deaths were recorded. Mortality rates in the population ranged from 5.19 to 8.94 / 100 thousand inhabitants (men: 7.84 and 14.59 / 100 thousand; women: 2.86 and 3.98 / 100 thousand). For both sexes, there is an increasing trend: male (b = 0.012; p-value = 0.000) and female (0.014; 0.020). For the age groups, the variations were: 10 to 19 years, between 6.71 and 3.96 / 100 thousand; 20 to 39 years, from 4.57 to 11.93 / 100 thousand; 40 to 59 years, between 10.21 and 11.53 / 100 thousand; and over 60 years, between 8.09 and 15.24 / 100 thousand. There is a growing trend in the 20 to 39 age group (0.017; 0.000). In the others, there is stationarity.
