Highlights

We assessed how neighbourhood safety relates to three types of smoking behaviour.

Neighbourhood safety was not significantly associated with current smoking.

Neighbourhood safety was associated with less heavy smoking and nicotine dependence.

The associations between safety and smoking behaviours varied by ethnicity.

Policies that improve safety may potentially contribute to less smoking.

Abstract

This study examines the associations between neighbourhood safety and three types of smoking behaviour, and whether these associations differ by sex, age, ethnicity and individual-level socio-economic position. Baseline data (2011–2015) from the The HEalthy LIfe in an Urban Setting (HELIUS) study (Amsterdam, the Netherlands) were used. Smoking behaviour was based on self-report. Heavy smoking was defined as smoking ≥10 cigarettes per day. Nicotine dependence was assessed using the Fagerström questionnaire. Geographic Information System techniques were used to construct local residential areas and to examine neighbourhood safety for these areas using micro-scale environmental data. Multilevel logistic regression analyses with 6-digit zip code area as a second level were used to assess the association between neighbourhood safety and smoking. In our study sample of 22,728 participants (18–70 years), 24.0% were current smokers, 13.7% were heavy smokers and 8.1% were nicotine dependent individuals. Higher levels of neighbourhood safety were significantly associated with less heavy smoking (OR = 0.88, 95% CI = 0.78–0.99) and less nicotine dependence (OR = 0.81, 95% CI = 0.69–0.95), but not with less current smoking (OR = 1.01, 95% CI = 0.91–1.11). The associations between neighbourhood safety and the three types of smoking behaviour varied by ethnicity. For instance, higher levels of neighbourhood safety were associated with less current smoking in participants of African Surinamese origin (OR = 0.71, 95% CI = 0.57–0.89), but not in those of Dutch (OR = 1.13, 95% CI = 0.91–1.39), South-Asian Surinamese (OR = 1.22, 95% CI = 0.95–1.55), Turkish (OR = 1.08, 95% CI = 0.84–1.38), Moroccan (OR = 1.53, 95% CI = 1.12–2.10) or Ghanaian (OR = 1.18, 95% CI = 0.47–2.94) origin. Policies that improve neighbourhood safety potentially contribute to less heavy smoking and nicotine dependence.
