Abstract

Background: We aim to assess the effect of a smoke-free beaches (SFB) intervention in Barcelona on smoking during the 2021 bathing season.

Methods: Quasi-experimental pre-post design (pre-intervention period: 15-28 May; post-intervention period: 29 May-12 September). Based on users' profiles and location, four beaches were assigned to the intervention group (IG) and five to the comparison group (CG). The intervention involved: a mayoral decree (29 May), a communication campaign and beach on-site information. We established two 3 m × 3 m transects per beach from the coastline to the promenade. Trained teams collected smoking-related information in the transects through observations and surveys to beach users. Outcomes are as follows: percentage of people reporting witnessing smoking behaviours the last fortnight and percentage of people observed smoking. We calculated and compared prevalence ratios (PRs) with adjusted Poisson regressions.

Results: 3751 interviews (1721 IG; 2030 CG) and 1108 observations (498 IG, 610 CG) were carried out. SFB were associated with a significant reduction in the percentage of people reporting witnessing smoking (IG (pre: 87.2%; post: 49.7%); CG (pre: 86.2%; post: 74.1%); PR (95% CI): 0.7 (0.6 to 0.8)); and in the users observed smoking in the beach (IG (pre: 3.8%; post: 3.0%); CG (pre: 2.3%; post: 9.9%); PR (95% CI): 0.3 (0.3 to 0.4)). Satisfaction scores were 8.3 (IG) and 8.1 (CG) out of 10.

Conclusion: An SFB intervention is an effective and well-accepted measure to reduce smoking and smokers' visibility. Smoke-free measures should be extended to beaches and other non-regulated outdoor areas.

对巴塞罗那无烟海滩干预措施的评估：一项准实验研究。

背景：我们旨在评估巴塞罗那无烟海滩（SFB）干预措施对2021年沐浴季节吸烟的影响：方法：准实验前-后设计（干预前时间：5月15日至28日；干预后时间：5月29日至9月12日）：方法：准实验前-后设计（干预前时间：5 月 15 日至 28 日；干预后时间：5 月 29 日至 9 月 12 日）。根据使用者的情况和地点，四个海滩被分配到干预组（IG），五个海滩被分配到对比组（CG）。干预措施包括：市长令（5 月 29 日）、宣传活动和海滩现场信息。我们在每个海滩从海岸线到海滨长廊建立了两个 3 米 × 3 米的横断面。经过培训的小组通过观察和对海滩使用者的调查，收集横断面上与吸烟有关的信息。结果如下：报告最近两周目睹吸烟行为的人数百分比和观察到的吸烟人数百分比。我们通过调整泊松回归计算并比较了流行率（PRs）：共进行了 3751 次访谈（1721 次 IG；2030 次 CG）和 1108 次观察（498 次 IG；610 次 CG）。SFB显著降低了目睹吸烟者的比例（IG（访谈前：87.2%；访谈后：49.7%）；CG（访谈前：86.2%；访谈后：74.1%）；PR（95% CI）：0.7（0.6-0.8））；显著降低了在海滩吸烟者的比例（IG（访谈前：3.8%；访谈后：3.0%）；CG（访谈前：2.3%；访谈后：9.9%）；PR（95% CI）：0.3（0.3-0.4））。满意度得分分别为 8.3（IG）和 8.1（CG）（满分 10 分）：SFB干预措施是减少吸烟和吸烟者能见度的有效且广为接受的措施。无烟措施应推广到海滩和其他非管制室外区域。
