The influence of environmental and health indicators on premature mortality: An empirical analysis of the City of Toronto's 140 neighborhoods

The objective of this paper was to assess the link between premature mortality and a combination of neighbourhood contextual (environmental and health) and compositional (socioeconomic and demographic) characteristics. We statistically and spatially examined six environmental variables (ultrafine particles, carcinogenic and non-carcinogenic pollutants, pollution released to air, tree cover, and walkability index), six health service indicators (number health providers, breast, colorectal and cervical cancer screening uptake rates, student nutrition program uptake rates, and healthy food index), and eight socioeconomic indicators (total income, Gini coefficient, two age categories – below and above 40 years, proportion of females to males, visible minorities, Indigenous peoples, education, less than grade 9) among 140 neighbourhoods of the City of Toronto in Ontario (Canada). We applied principal component analysis to identify patterns and to reduce the number of explanatory variables into combined component axes that represent unique variation in these confounded and overlapping factors. We then applied regression analysis to model the relationship between the indices of enviro-health and socioeconomics and their potential relationship with premature mortality. Residual spatial analysis was used to investigate any remaining spatial structure (such as neighbourhoods with higher residual premature mortality rates). Neighbourhood Equity Index was correlated with our enviro-health and socioeconomic indices. Premature mortality within neighbourhoods was predicted by poor cancer screenings, pollution, lack of tree canopy, increased uptake of student nutrition programs and high walkability index. A negative association between premature mortality and pollution was associated low walkability index and presence of visible minorities within neighbourhoods. There was some unexplained residual spatial variation in our model of premature mortality - especially along the shores of Lake Ontario and in neighbourhoods with major highways or road corridors: premature mortality in Toronto neighbourhoods was higher than expected along highway-corridor neighbourhoods and shorelines. Our analysis revealed a significant relationship between neighbourhood contextual features – both environmental and health – and premature mortality, suggesting that these contextual components of neighbourhoods can predict rates of urban premature mortality in Toronto.     

健康支持性环境对四川农村人群的不同血压水平的影响分析

目的 探讨健康支持性环境中的不同特征变量对四川省农村人群的不同血压水平的影响。方法 采用多阶段整群抽样的方法，随机抽取四川省7个县（区）8400名的18岁以上常住居民为调查对象。问卷调查一般人口学特征、身体活动行为特征和环境等信息。采用标准方法测量身高、体重、腰围和血压。采用无序多分类logistic回归分析。结果 本调查人群中共检出正常高值血压者4270例，检出率为50.83%，标化率为37.02%，平均年龄（56.22±14.89）岁；高血压患者1498例，检出率为17.83%，标化率为7.92%，平均年龄（65.26±11.28）岁。无序多分类logistic回归结果显示，住宿环境好、获得运动方面的健康信息和参与中等强度活动150Symbol~A@300min/周是正常高值血压和高血压人群的共同保护因素；住宿便利（OR=0.789, 95%CI:0.649~0.958, P=0.017）、医疗服务可及性便利（OR=0.686, 95%CI:0.509~0.924, P=0.013）、对健身步道和健身广场满意为高血压人群的保护因素。结论 多途径合理构建健康支持性环境，对农村正常高值血压者和高血压患者具有保护作用，对遏制农村高血压的流行现状起到一定作用。     

“调任通督”法针刺治疗围绝经期潮热的随机对照研究＊

目的 观察“调任通督法”针刺治疗围绝经期潮热的临床疗效和安全性。方法 将符合纳入标准的72例围绝经期潮热患者，按照1∶1的比例随机分为治疗组（针刺组）和对照组（等待组）。治疗组取穴百会、印堂、神庭、关元、气海、中脘、阴郄、太溪、复溜、三阴交。针刺治疗每次持续30 min，每周2次，连续治疗6周。对照组为等待组，试验期间仅给予同针刺组相同的健康宣教，两组分别于治疗前、治疗第3周、治疗第6周以及第10周随访评估其潮热频率和程度，以及更年期生活质量量表（Menopause-specific quality of life questionnaire，Men-QoL）的变化情况，同时记录针刺不良事件的发生。结果 ①潮热频率及潮热程度：在治疗后及随访时，针刺组较等待组有明显改善，差异具有统计学意义（P < 0.01）。与治疗前相比，针刺组第3周即出现了潮热频率明显下降的趋势（P < 0.01），治疗后以及随访期针刺组潮热频率及潮热程度均较治疗前有明显统计学差异（P < 0.01）。而等待组在各时间点潮热频率及潮热程度均无统计学差异（均P > 0.05）。②围绝经期生活质量量表：治疗后针刺组在Men-QoL总分、血管舒缩功能评分、社会心理、体能状况较等待组比较均有统计学差异（均P < 0.01）。在随访期，针刺组在Men-QoL社会心理以及体能方面明显改善，差异均具有统计学意义（P < 0.01，P < 0.05）。两组Men-QoL性功能在治疗后及随访期均无统计学差异（P > 0.05）。与治疗前相比，在治疗后及随访期，针刺组Men-QoL总分、血管舒缩功能、社会心理、体能状况均有统计学差异（均P < 0.05），在Men-QoL性功能方面无统计学差异（P > 0.05）。等待组在Men-QoL总分及四个域方面均无明显改善，无统计学意义（均P > 0.05）。结论 调任通督法针刺治疗围绝经期潮热安全有效，且对围绝经期生活质量有所改善。

高中一年级学生抑郁情绪及相关因素的研究

目的调查高中一年级学生的抑郁情绪及与其个性、心理健康水平、应对能力和家庭环境的关系。方法采用整群抽样方法和问卷式调查,共调查高一学生488名,资料填写完整者449人(92.01%)。结果449名高一学生SDS平均得分(标准分)为(47.27±10.86),抑郁情绪的发生率为37.86%,不同性别和文理科之间差异无统计学意义。抑郁情绪组性格内向、情绪稳定性差和精神质表现较为突出,其SCL-90的9个因子评分均高于对照组,个人积极应对能力和解决问题的能力差,消极应对和自责表现突出,家庭的亲密度、情感表达、娱乐性和组织性均较对照组差,矛盾性较对照组突出。结论抑郁情绪已是高一学生中较为常见而且需要关注的心理卫生问题,严重影响其心身健康发展,抑郁情绪与个性、心理健康评分、个人应对方式和家庭环境均具有显著关系。
