Impact of Tobacco Retail Outlet Density on Youth Smoking Risk in New Zealand

This study examines the correlation between the density of tobacco outlets around secondary schools in New Zealand and the prevalence of youth smoking behaviors, including current smoking, susceptibility to smoking, and tobacco purchasing. Results show varying adjusted odds ratios based on different retailer density zones, highlighting the potential influence of tobacco retail environments on youth smoking habits.

Tobacco retail outlet density and risk of youth smoking in New Zealand Louise Marsh, Ali Ajmal, Rob McGee, Lindsay Robertson, Claire Cameron, Crile Doscher Cancer Society Social & Behavioural Research Unit (SBRU) Te Hunga Rangahau rai Mate Pukupuku 25 years of social & behavioural research in cancer control

2. Tobacco retail outlets in New Zealand

3. Background Relationship between density of tobacco outlets around a school and risk of smoking among students Density higher with larger proportion of young people Experimental, current smoking, and susceptibility to smoking Purchasing tobacco Normalisation of smoking

4. Aim of the study This study investigates whether the density of tobacco outlets around secondary schools in New Zealand (500m and 1000m) is associated with current smoking, susceptibility to smoking, and purchasing of tobacco.

5. Density of tobacco retail outlets 500 and 1000m polygons Retailers Tobacco Only Tobacco and Alchool Secondary Schools Proximity of Tobacco Outlets n n n n Within 500 m only Within 0 to 1000 m only Within 500 to 1000 m only None within 1000 m

6. What did we find? Current smoking Retailer Density 500m of a school Adjusted odds ratio (95% CI) Reference 1000m of a school Adjusted odds ratio (95% CI) Reference 0 Density 0.89 (0.8, 0.99) 0.79 (0.65, 0.96) Low density 0.75 (0.65, 0.87) 0.8 (0.67, 0.96) High density

7. What did we find? Susceptibility to smoking Retailer Density 500m of a school Adjusted odds ratio (95% CI) Reference 1000m of a school Adjusted odds ratio (95% CI) Reference 0 Density 0.98 (0.89, 1.08) 1.03 (0.95, 1.11) Low density 1.09 (1.03, 1.14) 1.07 (1.01, 1.16) High density

8. What did we find? Purchasing tobacco Retailer Density 500m of a school Adjusted odds ratio (95% CI) Reference 1000m of a school Adjusted odds ratio (95% CI) Reference 0 Density 1.06 (0.75, 1.49) 1.16 (0.8, 1.68) Low density 1.18 (0.83, 1.67) 1.52 (1.07, 2017) High density

10. Implications: Retail endgame strategies Number of tobacco retail outlets represents a major form of promotion Further regulation of the retail environment Restricting the density or distance of tobacco outlets around schools Public support is high, even among smokers Policy measures
