The primary purpose of this article is to demonstrate the role that age, gender, and place play in rural-urban differences in mortality, in order to better develop policy to reduce these differences.
In 2006, the Canadian Institute for Health Research published a major epidemiological investigation into the morbidity and mortality experience of Canadians, using mortality data as well as the 2004 Canadian Community Health Survey. Using these data, gender differences in mortality across the rural-urban continuum were further explored. The proportion of excess deaths occurring in each of the four different types of rural places, relative to deaths in urban places, were calculated for different gender and age groups.
Differences in mortality across the urban-rural continuum are mainly driven by people under 45 years, and are particularly due to deaths caused by injury and poisoning, motor vehicle accident (MVA) and suicide. The proportion of excess deaths relative to urban places for those under 45 years increases with decreasing age. Remote places have the highest excess in mortality for suicide, MVA, injury and poisoning, relative to urban places.
The relative mortality for young girls living in rural compared with urban places is similar to the relative mortality for young rural boys. There is, therefore, a need for prevention policies targeted at both boys and girls to prevent suicide, injury/poisoning, and MVAs in rural, and especially in remote, places.
本文的主要目的是阐述年龄、性别和地域在城乡死亡率差异中所起的作用,以便更好地制定政策来缩小这些差异。
2006年,加拿大卫生研究院利用死亡率数据以及2004年加拿大社区健康调查,发表了一项关于加拿大人发病和死亡情况的重大流行病学调查。利用这些数据,进一步探讨了城乡连续体中死亡率的性别差异。针对不同性别和年龄组,计算了四类不同农村地区相对于城市地区的超额死亡比例。
城乡连续体中的死亡率差异主要由45岁以下人群导致,尤其归因于伤害和中毒、机动车事故(MVA)及自杀造成的死亡。45岁以下人群相对于城市地区的超额死亡比例随年龄降低而增加。相对于城市地区,偏远地区在自杀、MVA、伤害和中毒方面的超额死亡率最高。
农村年轻女孩相对于城市年轻女孩的相对死亡率与农村年轻男孩相对于城市年轻男孩的相对死亡率相似。因此,需要制定针对男孩和女孩的预防政策,以预防农村尤其是偏远地区的自杀、伤害/中毒和MVA。
