We investigated differences in risk factors and preventive behaviors by age and sex among persons with reported Lyme disease in Ontario, Canada, during 2015-2022. Incidence rates peaked among children 5-9 and adults 50-79 years of age. Median age was higher for female than male case-patients (54 vs. 51 years). Male case-patients reported more activity in wooded and tall grass areas than did female case-patients; fewer male case-patients reported sharing living space with outdoor-exposed companion animals. As age increased, more case-patients reported activity in blacklegged tick habitats, exposure to ticks, and wearing adequate clothing, but fewer reported sharing living space with outdoor-exposed companion animals. Adoption of preventive behaviors was relatively low and did not differ by sex. Male case-patients, children 5-9 years of age and their parents or caregivers, and adults >59 years of age represent populations that would benefit from tailored public health messaging on Lyme disease prevention.
我们调查了 2015 年至 2022 年期间在加拿大安大略省报告的莱姆病患者的年龄和性别差异的风险因素和预防行为。发病率在 5-9 岁儿童和 50-79 岁成年人中达到峰值。女性病例患者的中位年龄高于男性病例患者（54 岁比 51 岁）。男性病例患者比女性病例患者报告更多在树木繁茂和高草丛地区活动；较少的男性病例患者报告与户外暴露的伴侣动物共享生活空间。随着年龄的增长，更多的病例患者报告在黑腿蜱栖息地活动、接触蜱虫和穿着适当的衣服，但较少的病例患者报告与户外暴露的伴侣动物共享生活空间。预防行为的采用率相对较低，且与性别无关。男性病例患者、5-9 岁儿童及其父母或看护人以及>59 岁的成年人是需要针对莱姆病预防进行量身定制的公共卫生宣传的人群。
