Do social support and community engagement act as mechanisms in the association between neighbourhood income inequality and the mental health of mothers in Calgary,Canada? A mediation analysis

PurposeAccording to the social determinants of health framework, income inequality is a potential risk factor for adverse mental health. However, few studies have explored the mechanisms suspected to mediate this relationship. The current study addresses this gap through a mediation analysis to determine if social support and community engagement act as mediators linking neighbourhood income inequality to maternal anxiety and depressive symptoms within a cohort of new mothers living in the City of Calgary, Canada.MethodsData collected at three years postpartum from mothers belonging to the All Our Families (AOF) cohort were used in the current study. Maternal data were collected between 2012 and 2015 and linked to neighbourhood socioeconomic data from the 2006 Canadian Census. Income inequality was measured using Gini coefficients derived from 2006 after-tax census data. Generalized structural equation models were used to quantify the associations between income inequality and mental health symptoms, and to assess the potential direct and indirect mediating effects of maternal social support and community engagement.ResultsIncome inequality was not significantly associated with higher depressive symptoms (β = 0.32, 95%CI = −0.067, 0.70), anxiety symptoms (β = 0.11, 95%CI = −0.39, 0.60), or lower social support. Income inequality was not associated with community engagement. For the depression models, higher social support was significantly associated with lower depressive symptoms (β = −0.13, 95%CI = −0.15, −0.097), while community engagement was not significantly associated with depressive symptoms (β = 0.059, 95%CI = −0.15, 0.27). Similarly, for the anxiety models, lower anxiety symptoms were significantly associated with higher levels of social support (β = −0.17, 95%CI = −0.20, −0.13) but not with higher levels of community engagement (β = 0.14, 95%CI = −0.14, 0.41).ConclusionThe current study did not find clear evidence for social support or community engagement mediating the relationship between neighbourhood income inequality and maternal mental health. Future investigations should employ a broader longitudinal approach to capture changes in income inequality, potential mediators, and mental health symptomatology over time.     

互联网形势下医院离退休干部管理工作探索

当前我国科技技术进一步提升,国民生活水平也在不断地进步,对于医院离退休干部管理服务的要求也越来越高。对于医院的工作来说,处理好医院的退离休老干部是一项十分重要的工作,所以医院工作管理人员需要提高对于离退休老干部管理工作的重视。而在传统意义下医院离退休干部的管理服务,存在着较多的问题,而当前在互联网的形势下却能够实现更加具有科学化、合理化的服务。通过创新服务理念,对于管理方式进行改革,可以有效地改善当前对于医院离退休干部的管理服务水平,青年团员可以自行组成相应的志愿者,加强对于退休老人的关心,了解老干部在生活以及学习中出现的问题,并且采取有效的措施进行解决。本文通过以阐述我国当前离退休干部管理工作的现状作为切入点,进行分析探究,进一步提出互联网模式下提高我国医院离退休干部管理的对应措施。     

2009-2018年资阳市手足口病流行病学及病原学特征分析

目的 研究2009-2018年资阳市手足口病的流行病学及病原学特征，为有效防控手足口病提供理论依据。方法 从中国疾病控制中心监测信息报告管理系统获取以乡镇为单位的手足口病数据，进行三间分布描述，利用ArcGIS 10.1软件制作专题地图。结果 资阳市2009-2018年累计报告病例19195例，年平均发病率为61.72/10万，虽总体上呈升高的趋势；各乡镇均有手足口病报告；每年有两个发病高峰，分别是5-7月和9-11月，其中5-7月为主高峰，9-11月为次高峰；男女性别比为1.44[DK]∶1，5岁以下儿童共发病18209例，占比为94.9%。2015年之前优势毒株为EV71和CoxA16，2015年之后优势毒株为其他肠道病毒。结论 资阳市手足口病发病呈持续升高态势。手足口病的优势毒株近年来在改变，应增加人肠道病毒的监测种类，落实综合性防控措施，预防和控制手足口病的流行。     

昆明市2013-2017年丙型病毒性肝炎流行特征及趋势分析

目的分析昆明市2013-2017年丙型病毒性肝炎的流行特征和流行趋势,为科学制定防控策略提供依据。方法运用描述性流行病学方法,统计昆明市2013-2017年丙型病毒性肝炎的发病情况,分析其流行特征和趋势。结果昆明市2013-2017年丙型病毒性肝炎呈现先上升后下降的趋势,2015年达到发病高峰,其发病率高达32.80/10万,总体上2013-2017年丙型病毒性肝炎发病率呈现上升趋势,且肝炎和丙肝以官渡区、五华区和西山区为主要的高发地区;无明显的季节性特点,四季均有发病;易发生丙型病毒性肝炎的人群为35~50岁的农民和家务及待业人员。结论昆明市丙型病毒性肝炎发病状况并不乐观,应加强丙肝防控力度,重点关注高发地区和高发人群,通过有效举措控制丙型病毒性肝炎的发病率。     

Preventing heart disease: is treating the high risk sufficient?

Monte Carlo simulation was used to assess the effects of several intervention strategies on coronary heart disease mortality rates in a Finnish and a North American cohort. Lowering total serum cholesterol by 4%, smoking by 15%, and diastolic blood pressure by 3% for the whole cohort would be expected to reduce the incidence of non-fatal myocardial infarction by at least 13% and coronary heart disease deaths by at least 18%. Lowering serum cholesterol by 34%, diastolic blood pressure to 90 mmHg, and reducing smoking by 20% in the subset of the population with all three risk factors in the highest quartile would result in a 6-8% reduction in non-fatal myocardial infarction and a 2-9% reduction in deaths from coronary heart disease in these cohorts. These data demonstrate that in populations with a relatively high incidence of heart disease, treating the entire population will produce larger effects than focusing only on high-risk populations.

原位肛门整形重建术的研究

目的：探讨改进的内外括约肌在原位肛门整形重建术中的应用及其手术效果。方法：改进包括：①肛门内括约肌改进为双层双环肌套；②肛门外括约肌改进为股薄肌采用“围巾式”环绕结肠末端一周，其远端剖为两条，一条缝合固定于耻骨韧带；另一条缝合固定于骶尾韧带，即为肛门外括约肌重建和外括约肌浅部和深部的重建。结果：38例术后肛门外形及功能和远期生活质量、生存率均更为满意。术后随访总优良率达94．73％；远期生存率达76．32％。结论：低位直肠癌Miles术后，同时行改进的内外括约肌原位肛门整形重建的效果是可行的，更接近正常的肛门解剖结构和生理功能。     

1994～2002年广西甲型副伤寒和伤寒流行情况分析

目的 了解1994～2002年接种伤寒Vi疫苗后的7年间伤寒和副伤寒流行变化，评价Vi疫苗对控制伤寒流行的效果并分析甲型副伤寒的特征及影响其爆发流行的因素。方法对自治区疾病控制中心实验室记录、伤寒副伤寒爆发调查报告、监测系统资料、全区伤寒流行地区伤寒Vi疫苗供应情况进行统计分析。结果 经过血培养证实甲型副伤寒病例为1200例、伤寒为285例；甲型副伤寒与伤寒的流行病学、临床特征十分相似；饮用污染水是引起甲型副伤寒爆发的主要原因；从1999年起，甲型副伤寒杆菌开始超过伤寒菌为优势流行菌株。结论 在广泛使用伤寒Vi疫苗后，伤寒基本得到控制，但因为引起副伤寒发病的危险因素依然存在，甲型副伤寒已取代寒，成为广西农村地区的最重要的传染病之一。为控制甲型副伤寒的流行，在安全饮用水供应状况得到全面改善之前，应尽快研制出副伤寒疫苗。
