Exploring How the Interplay Between Neighborhood Perceptions and Social Cohesion Relates to Self-Assessed Health: A...

Area of Science:

• Public Health
• Sociology
• Epidemiology

Background:

• Neighborhood characteristics like unsafety, disorder, and social cohesion are linked to health outcomes.
• Understanding the pathways (mediation, interaction) through which these factors influence self-assessed health (SAH) is crucial for public health interventions.

Purpose of the Study:

• To investigate whether perceived neighborhood unsafety and disorder affect SAH directly, through mediation by social cohesion, or via interaction with social cohesion.
• To decompose the total effects of neighborhood factors on SAH into components of mediation and interaction.

Main Methods:

• Analysis of longitudinal data from 5650 respondents in the GLOBE study (Netherlands) over 10 years.
• Log-linear regression to estimate total effects of perceived unsafety and disorder on poor SAH.
• Four-way decomposition to differentiate between direct, mediated, and interaction effects via social cohesion.

Main Results:

• Feeling unsafe showed a significant positive total effect on poor SAH (RR=1.05).
• Perceived neighborhood disorder also had a small positive total effect on poor SAH (RR=1.01).
• Decomposition revealed the effect of unsafety on SAH was primarily a controlled direct effect, with no significant mediation or interaction through social cohesion. No significant decomposition components were found for neighborhood disorder.

Conclusions:

• Perceived neighborhood unsafety and disorder appear to influence self-assessed health through direct pathways.
• Social cohesion does not mediate or moderate the relationship between neighborhood disorder/unsafety and self-assessed health.
• Neighborhood factors and social cohesion impact health independently, suggesting distinct intervention targets.
