Aging alone and financial insecurity predict depression: a path analysis of objective and subjective indices.

Objectives: This study draws on conservation of resources theory and transactional stress theory to guide our understanding of how social isolation, financial insecurity, and social support serve as a balance of both risk and protection for late-life depression.

Methods: Data were from the Leave-Behind Questionnaire in the 2016 ( = 4293) and 2018 ( = 4714) waves of the Health and Retirement Study. We conducted a cross-sectional path analysis via structural equation modeling, including objective and subjective perspectives.

These techniques are very costly or reduce the efficacy of the pest control product and have not been implemented by US agriculture.
