Social factors and suicidal ideation in adulthood

INTRODUCTION: In recent years, it has been possible to corroborate that people’s social environment is a key aspect in the study of suicide risk. OBJECTIVES: The aim of this study is to assess the relation between suicidal ideation and social factors (loneliness, social support, trust, participation and cohabiting) in a representative sample of the Spanish adult population, comparing the effect according to sex different age groups (18-49, 50-64, ≥65 years). METHODS: Cross-sectional study of a representative sample of the Spanish population (n = 4,217) conducted between 2011 and 2012. Loneliness was assessed using the UCLA Loneliness Scale. Social support was assessed using the OSLO-3 Social Support Scale, and participation scale and trust. Data were analyzed using logistic regression models adjusting for sex, sociodemographic and health variables (lifestyles, depression, and multimorbidity). RESULTS: Prevalence rates of suicidal ideation were higher in young and middle-aged adults. In the middle-aged groups, loneliness is significantly associated with suicidal ideation in both women and man. Among man, cohabiting and trust were identified as a protective factors of suicidal ideation. Among women, only social support was identified as a protective factor. In the older adult’s group, trust acted as a protective factor of suicide ideation among women. For man was the social support. Among younger adults, cohabiting was identified as a protective factor in man.
