Neighbourhood problems lead to depression, but effects vary across countries

Neighbourhood characteristics are linked to mental health in older age, but the magnitude of effects might differ across countries. Using data from 16 different countries, our paper in the American Journal of Epidemiology indicated that country-level social, political, economic and environmental characteristics may explain differences in how neighbourhood affects mental health.

Depression, local area and macro-level context

Depression is a common mental disorder with substantial disability and economic burden worldwide. More than 10% of adults aged 50 years and older present depressive symptoms with an even greater proportion of the population suffering in older age groups. Older adults spend more time in their neighbourhood, so that social and physical features of the residential area become increasingly important for them.

Signs of neighbourhood disorder, such as crime, vandalism and exposure to rubbish, are thought to indicate problems in the residential environment, by elevating the level of stress and fear among residents. On the other hand, positive aspects of neighbourhoods such as social cohesion – which is often characterised as a sense of community, help and support among neighbours – have the potential to buffer the effects of stress and contribute to healthy ageing. Both neighbourhood disorder and social cohesion has been linked to mental health problems.

Neighbourhoods are situated within macro-level environments capturing larger geographic areas such as local authorities, counties or even countries (Figure 1). Policies, as well as social, economic and environmental characteristics of macro environments can affect citizens’ life and health, and also shape the physical and social characteristics of local communities, where people live and age. It is important, as both local and macro-level environments are modifiable, presenting opportunities for improving population mental health and contributing to healthy ageing.

Neighbourhoods influence mental health among older adults

We investigated the associations between neighbourhood disorder, lack of social cohesion and depression among adults aged 50 and over. Longitudinal information on perceived neighbourhood characteristics and depressive symptoms across 16 high-income countries were utilised, including 32000 older adults. Results showed that living in an area with significant neighbourhood disorder increased the chance of developing depression (Figure 2), and so did lack of social cohesion (Figure 3). If people were already in retirement, effects became stronger.

Odds Ratios <1.0 indicate decreased odds of depression by exposure to neighbourhood disorder; Odds Ratios >1.0 express increased odds.

Neighbourhood effects differ across countries

As the magnitude of the associations varied across the 16 included countries, we further explored country-level differences.

Odds Ratios <1.0 indicate decreased odds of depression by lack of social cohesion; Odds Ratios >1.0 express increased odds. Small black diamonds are country-specific estimates, larger empty diamonds are pooled effects across group of countries.

Amongst other, we found that in countries with higher population density, lack of social cohesion was more detrimental for mental health. Particularly in the oldest age groups, where limited mobility is more likely present, neighbours can be an important source of social and emotional support. In countries where people live closer to each other, not having proper social ties to neighbours can lead to social isolation and higher risk of developing mental health problems.

Also, in countries with higher pension spending, the adverse effect of neighbourhood disorder on depression was buffered for individuals already in retirement. It is plausible that by providing material resources, more generous welfare states equip older people to deal with stressors arising from less safe and deteriorated residential neighbourhoods.

Macro-level context and policy recommendations

Understanding how larger context can influence mental health inequalities across neighbourhoods has the potential to inform policy, and provide more tailored recommendations. For example, tackling crime and vandalism in countries with lower pension spending would be particularly beneficial for mental health, as older people has less material resources to protect themselves from the negative effects of neighbourhood disorder. Supporting social ties and improving social capital in densely populated areas may stronger contribute to healthy ageing and lead to better mental health among older adult.

Empowering communities: An interactive tobacco and alcohol outlet density webmap for Scotland

Today we are launching an interactive webmap that allows users to map tobacco and alcohol outlet density, and related health outcomes, for neighbourhoods (‘datazones‘) across Scotland.  The underlying data we have collected and assembled can also be freely downloaded for use.  Our research from Scotland shows that outlet density matters for health:

  • areas with the highest alcohol outlet density have double the death rate of those with the lowest densities (see our blog postreport and infographic)
  • adolescents living in areas with the highest tobacco outlet density are almost 50% more likely to smoke than those with the lowest (see our blog post, paper and infographic).

ALCOHOL OUTLET DATA UPDATED 25 JUNE 2015:  Previous to this date the alcohol outlet density data had used an alternate measure of density than outlets per km2, resulting in values that were typically 30-40% lower than the actual value.  Whilst the figures have changed the general picture has not: an area of high density remains an area of high density.  The rest of the data are unaffected.
