Poor, violent urban neighborhoods ups depression in older adults
Older adults who live in poor and violent urban neighbourhoods are at a greater risk of depression, a new study reveals. The study appeared in the journal Health & Place. According to researchers from the University of California in the US, older adults who lived in neighbourhoods with more homicide and a higher poverty rate experienced more depressive symptoms. “Given the shift towards an ageing population and the growing rates of depression among older adults, understanding the factors that contribute to depression is critical,” said the first author of the study Spruha Joshi from the University of Minnesota’s school of public health in the US. “Older adults tend to be less mobile and more dependent on the amenities, services and sources of social support in the neighbourhoods where they live,” Joshi said. The researchers did a three-year study of elderly residents in the nation’s most populous city. Depression was measured using the nine-question Patient Health Questionnaire. They looked at several neighbourhood factors that might contribute to depression, such as high homicide rates, poor perception of safety, pedestrian and bicyclist injuries, green space, social cohesion and walkability. The study sample was 61 percent female and 47 percent non-Hispanic white. In addition, 60 percent of respondents had incomes below $40,000 dollars. While many factors were examined, violence was the only neighbourhood characteristic that substantially contributed to depression in older adults in impoverished, urban communities. “We wanted to investigate the total effect poverty has on older adult depression, but also look at particular characteristics which might explain that relationship,” said senior study author Magdalena Cerdá. “We found that about 30 percent of the relationship between neighbourhood poverty and depression was explained by the higher homicide rate,” Cerdá stated. These findings could help shape policy to improve the quality of life for older adults in urban neighbourhoods. “The study highlights the key role that violence can play in shaping the mental health of local residents. By investing in violence prevention in high-poverty neighbourhoods, it’s possible to reduce violence and improve the mental health of vulnerable populations, Cerdá explained.
