BACKGROUND
The incidence of cutaneous melanoma (CM) is increasing at an alarming rate in Canada and elsewhere around the world. Significant regional differences in CM incidence have been identified in Atlantic provinces. The goal of this study is to compare ultraviolet exposure, sun protective behaviours, level of worry and baseline CM knowledge in provinces with a high versus low incidence of CM as well, as between various demographic groups.
METHODS
A cross-sectional survey study was conducted in Atlantic provinces between July 2020 and August 2022. All participants aged ≥ 16 years with a completed survey were eligible. Survey responses were summarized using frequency counts, percentages, and means. Two-sided Z-tests for equality of proportions and logistic regression models were used to compare the survey results between geographic and demographic groups.
RESULTS
In total, 7861 participants were included (28.0% men; mean age 61.3 years; response rate 28%). Our results (gender- and age-adjusted odds ratio, 95% confidence interval) show that high-incidence provinces for CM (Prince Edward Island and Nova Scotia) had significantly more sunburns (OR 2.00, 1.72-2.31), total sun exposure (OR 2.05, 1.68-2.50), recreational sun exposure (OR 1.95, 1.61-2.35) and tans (OR 1.77, 1.53-2.05) than individuals in low-incidence provinces (Newfoundland and Labrador). However, individuals in high-incidence provinces displayed more protective behaviors: there were less tanning bed users (OR 0.82, 0.71-0.95), they checked their skin more frequently for new moles (OR 1.26, 1.06-1.51) and practiced more sun protection overall. Additional analyses are presented based on education, income, sexual orientation and gender.
DISCUSSION
These findings suggest that future efforts aimed at reducing the CM burden in Atlantic Canada should be tailored for target geographic and/or demographic groups.
LIMITATIONS
the study participants are not representative of the population in Atlantic Canada due to recruitment strategies.
背景
在加拿大及世界其他地区，皮肤黑色素瘤（CM）的发病率正以惊人的速度上升。在大西洋省份已发现CM发病率存在显著的地区差异。本研究的目的是比较CM高发病率省份与低发病率省份之间，以及不同人口群体之间的紫外线暴露情况、防晒行为、担忧程度和CM基础知识水平。
方法
2020年7月至2022年8月在大西洋省份进行了一项横断面调查研究。所有年龄≥16岁且完成调查问卷的参与者均符合条件。调查回复通过频数、百分比和均值进行汇总。使用双侧Z检验进行比例相等性检验，并采用逻辑回归模型比较地理和人口群体之间的调查结果。
结果
总共纳入了7861名参与者（男性占28.0%；平均年龄61.3岁；回复率28%）。我们的结果（经性别和年龄调整的优势比，95%置信区间）表明，CM高发病率省份（爱德华王子岛和新斯科舍省）的晒伤（优势比2.00，1.72 - 2.31）、总日照时间（优势比2.05，1.68 - 2.50）、休闲日照时间（优势比1.95，1.61 - 2.35）和晒黑（优势比1.77，1.53 - 2.05）显著多于CM低发病率省份（纽芬兰和拉布拉多省）的个体。然而，高发病率省份的个体表现出更多的保护行为：使用晒黑床的人较少（优势比0.82，0.71 - 0.95），他们更频繁地检查皮肤是否有新痣（优势比1.26，1.06 - 1.51），并且总体上采取了更多的防晒措施。还基于教育程度、收入、性取向和性别进行了额外分析。
讨论
这些发现表明，未来旨在减轻加拿大大西洋地区CM负担的努力应针对目标地理和/或人口群体进行调整。
局限性
由于招募策略，研究参与者不代表加拿大大西洋地区的人口。
