Air Quality in Hamilton: Who is Concerned? Perceptions from Three Neighbourhoods

This study investigates the factors influencing perceptions of air quality in the industrial city of Hamilton, Canada. The research employs data collected via a telephone survey of 1,002 adult residents in three neighbourhoods. Perceptions in the neighbourhoods were examined by individual socio-demographic factors (age, gender, marital and immigrant status, education, etc.) in addition to perceived health status and neighbourhood problems (environmental, social and safety concerns). Neighbourhood variations were found, with those residing in the Southwest Mountain neighbourhood being over 6 times more likely to report a ??good?? perception of air quality than those residing in the Lower City neighbourhood. In addition, factors influencing these perceptions also varied by neighbourhood. Perceived neighbourhood problems strongly influenced perceptions of air quality in the Lower City and Central areas, whereas socio-demographic factors were significant primarily in the Lower City neighbourhood, suggesting the importance of these mediating dimensions; pointing to less of a concern about air quality. There was, however, remarkable consistency in all three neighbourhoods when respondents were asked whether their perception of air quality affected their choice to go outside. Overall, the presence or absence of perceived problems, such as pollution and safety, had a powerful effect on shaping and differentiating neighbourhood responses.     

我国人口流动中的健康选择机制研究

利用2008年中国流动与健康调查数据,对农村留守人口、农村外出返乡人口、乡城流动人口以及城镇居民等不同流动特征群体之间的健康差异进行比较,并系统检验了我国人口流动过程中的两种健康选择机制——"健康移民"(healthy migrant)效应和"三文鱼偏误"(salmon bias)效应。模型分析结果表明,我国人口流动存在着较为明显的"健康移民"和"三文鱼偏误"选择效应。在控制被访者的年龄、性别、主要社会经济特征以及相关健康行为后,流动人口自评一般健康、慢性病状况、经常性身体不适和肺活量等健康指标显著优于农村留守人口,乡城流动人口患有慢性病和出现经常性身体不适的可能性也显著低于农村返乡人口。在控制相关变量后,乡城流动人口与城镇居民的健康状况(除慢性病和心率过高症状外)不存在显著差别。     

Exercise,Eating Patterns,and Obesity: Evidence from the ATUS and Its Eating &; Health Module

Time spent eating and exercising can impact quality of life measures such as general health and risk for obesity. This article links data from the American Time Use Study and the Eating and Health Module to explore exercise and eating patterns for varying age groups, over different times of day, and by self-reported health status. Younger Americans who did some exercise were more likely to engage in higher impact sports. Older Americans who exercised were more likely to do so in the morning. Americans who reported being in excellent health spent more time exercising than other self-reported health groups, regardless of their sex or age.     

Quality of life indicators and health: Current status and emerging conceptions

Quality of life is an increasingly common theme in the health status and health promotion literatures. Six approaches that consider quality of life and health are reviewed. These are (a) health-related quality of life; (b) quality of life as social diagnosis in health promotion; (c) quality of life among persons with developmental disabilities; (d) quality of life as social indicators; (e) the Centre for Health Promotion (University of Toronto) model, and (f) Lindstrom's quality of life model. Each approach is considered as to its emphasis on objective or subjective indicators, individual or system-level measurement, value-laden or value-neutral assumptions, and potential relationship to social policy and social change goals. The links among the social indicators, quality of life, and health promotions areas are examined.     

Women,Marital Status,and Symptoms of Depression in a Midlife National Sample

ABSTRACT

Previous studies of the correlates of depression among women have not generally been based on adequate midlife samples or precision in the specification of marital status categories. The present analysis is designed to address these deficiencies and is based on data from the Health and Retirement Survey-Wave 1 (i.e., respondents 51 to 61 years old). Results indicate that married women are less likely to report symptoms of depression than their unmarried counterparts. The mental health benefits of marriage are greater for men than for women. Moreover, other variables, such as marital satisfaction, self-rated health, and employment status are more powerful predictors of emotional well-being in midlife than marital status per se. The quality of marriage affects depressive symptoms more strongly for women than men.     

Population growth and air quality in California

Demographers are often interested in the environmental impacts of population growth. I examine the impact of growth specifically on air quality in California. In recent decades, California has suffered from notoriously polluted air and has experienced rapid population growth. Despite the population .growth, air quality actually has improved since the early 1980s due to aggressive regulatory efforts. Using data for 56 counties, I analyze the contribution of population growth to trends in atmospheric emissions of five regulated pollutants from 1980 to 1990, controlling for trends in per capita income and regulatory efforts. The analysis is disaggregated by source of emissions and demonstrates that population growth is strongly associated with some sources of emissions but not with others. Thus, the overall impact of population growth depends upon the composition of production and consumption activities in each county. I also explore whether the trend in number of households predicts better than the trend in number of persons, and whether the impact of population growth depends upon the age structure or source of growth (immigration or domestic increase). Generally, these alternative specifications of population do not improve the models of atmospheric emissions.

Good Health is Not the Same as a Good Life: Survey Results from Brandon,Manitoba

The aim of this investigation was to obtain some baseline self-reported data on the health status and overall quality of life of a sample of residents of the city of Brandon, Manitoba aged 18 years or older, and to measure the impact of a set of designated health determinants, comparison standards and satisfaction with diverse domains of life on their health and quality of life. In May and June 2010, 2,500 households from the city of Brandon, Manitoba were randomly selected to receive a mailed out questionnaire and 518 useable, completed questionnaires were returned. Baseline health status data were obtained using the 8 SF-36 dimensions of health and 13 items from the United States Centers for Disease Control and Prevention, Behavioral Risk Factor Surveillance System. Determinants of health and overall quality of life included measures of socializing activities, a Good Neighbourhood Index, Social Support Index, Community Health Index, a measure of free-time exercise levels, health-related behaviours, use of drugs, health care issues, a set of domain-specific quality of life items, a set of measures concerning criminal victimization, worries and behaviours concerning victimization and the basic postulates of Multiple Discrepancies Theory. Overall life assessment, dependent variables included Average Health, happiness, a single item measure of satisfaction with life as a whole, a single item measure of satisfaction with the overall quality of life, the Satisfaction With Life Scale, Contentment with Life Assessment Scale and a Subjective Wellbeing Index. Using multiple regression, we explained as much as 75% of the variance in Subjective Wellbeing scores and as little as 45% in happiness scores. Four clusters of health determinants explained from 20% (Happiness) to 44% (Average Health) of the variance in the dependent variables. Adding comparison standards and domain satisfaction scores to the set of health determinants increased our total explanatory power by only 2% points for Average Health (from 44 to 46%), but more than doubled our explanatory power for Happiness (from 20 to 45%) and for satisfaction with the overall quality of life (from 31 to 67%). As well, our explanatory power for the single item of Life Satisfaction increased from 34 to 66%, for the Satisfaction With Life Scale from 39 to 74%, for the Contentment With Life Assessment Scale from 36 to 60%, and for Subjective Wellbeing from 42 to 75%. This provided very clear evidence that self-perceived good health is not equivalent to perceived quality of life, confirming evidence reported in our earlier studies. The three most important take-home messages from this investigation are (1) in assessing the relative influence of any alleged determinants of health and the quality of life, different sets of alleged determinants will appear to be more or less influential for different dependent variables. Therefore, (2) researchers should use diverse sets of determinants and dependent variables and (3) it is a big mistake to use measures of health status as if they were measures of the perceived quality of life.     

Quality of life after radiation therapy: A study of 309 cancer survivors

(1) Comparison of patients with a national sample reveals no difference in income (adjusted for inflation), marital status and education level but patients, who are typically older, are more often retired or disabled. (2) Overall, perceived quality of life is nearly the same for patients and national sample; apparent differences can be readily explained by factors other than cancer or its treatment. (3) While some minor differences among patients were found as a function of their site of cancer, treatment modality, or health status, no evidence was found of significant detrimental effects due to radiation therapy or perceived quality of life. (4) Contrary to expectations of deteriorated quality of life, compared to the national baselines the patients are actually more satisfied with their lives as a whole.

Moving Beyond Salmon Bias: Mexican Return Migration and Health Selection

Despite having lower levels of education and limited access to health care services, Mexican immigrants report better health outcomes than U.S.-born individuals. Research suggests that the Mexican health advantage may be partially attributable to selective return migration among less healthy migrants—often referred to as “salmon bias.” Our study takes advantage of a rare opportunity to observe the health status of Mexican-origin males as they cross the Mexican border. To assess whether unhealthy migrants are disproportionately represented among those who return, we use data from two California-based studies: the California Health Interview Survey; and the Migrante Study, a survey that samples Mexican migrants entering and leaving the United States through Tijuana. We pool these data sources to look for evidence of health-related return migration. Results provide mixed support for salmon bias. Although migrants who report health limitations and frequent stress are more likely to return, we find little evidence that chronic conditions and self-reported health are associated with higher probabilities of return. Results also provide some indication that limited health care access increases the likelihood of return among the least healthy. This study provides new theoretical considerations of return migration and further elucidates the relationship between health and migration decisions.     

Comparing Self-Rated Health, Satisfaction and Quality of Life Scores Between Diabetics and Others Living in The Bella Coola Valley

Objective: To investigate the relative effect that diabetes has on self-rated health, satisfaction with various specific domains of life, and satisfaction with quality of life operationalized as happiness, satisfaction with life as a whole, and satisfaction with overall quality of life. Design: Mixed methods – mailed survey and chart review. Study Population: All people aged 17 years or older, residing in the Bella Coola Valley in September 2001 and having a chart at the Bella Coola Medical Clinic. Main outcome measures: Self-rated health, self-rated stress, rating of self-care received, global life satisfaction (Life as whole; Overall standard of living; Overall quality of life; and Overall happiness); and satisfaction with various domains of life. Results: A total of 968 useable surveys were returned for a response rate of 56 (968/1734). Age was negatively related to General Health, but positively related to Life Satisfaction. Not being of Aboriginal descent was positively related to all of the four global health indicators and to Subjective Well-Being. After accounting for age, race, and weight, we found that diabetics report significantly poorer self-rated health, and lower satisfaction with health scores compared to people without diabetes. Participants with diabetes who were the least compliant with their treatment regimens rated their current health significantly lower than those who were the most compliant. People with diabetes were, however, no more likely to be unhappy or dissatisfied with their lives as a whole or with the overall quality of their lives compared to people without diabetes. Among people with diabetes, however, those who used insulin did report significantly less satisfaction with the overall quality of their lives than those who didn’t use insulin. Conclusion: Diabetics understand they have poorer health than others, but they do not have poorer global life satisfaction scores. This may explain why it is difficult to get diabetics to adopt behaviours which may lower their quality of life – e.g., diet plans, lose weight, engage in exercise programs, or take medications.     

Using quality of life information to set priorities in health policy

Health care has as primary objectives extending life expectancy and improving quality of life in years prior to death. This paper offers a General Health Policy Model as a method for quantifying these outcomes. The model adjusts life expectancy for diminished quality of life, which is measured using a standardized instrument known as the Quality of Well-being (QWB) scale. The Well-year or Quality Adjusted Life Year (QALY) results from these analyses and serves as a single quantitative expression of health benefit. QALY units integrate side effects and benefits of treatment by combining into a single number, mortality, morbidity, and duration of each health state. Examples show the application of the model relevant to a variety of medical and public health problems, including diabetes, arthritis, AIDS, neonatal circumcision, and tobacco tax. It is suggested that the General Health Policy Model has advantages for guiding both individual and public health decisions.     

中国女性的社会地位及其影响因素

女性对自身社会地位的主观评估主要取决于对自我能力的认可程度、母亲和自己的受教育水平、以及所居住区域的性别文化性质。对自己的能力树立信心是女性社会地位提高的一个与心理或性格相关联的先决条件,而教育投入则是提升女性社会地位一块不可或缺的重要基石。大男子区域文化不仅不合理地降低女性的社会地位,而且还让处于不平等社会地位中的女性感到自我满足。要进一步改善我国妇女的社会地位,就必须在注意提高妇女自信的心理素质和自强的教育素质的同时,从社区和社会层面消除以男权为核心的传统性别文化。     

Subjective Health-Related Quality of Life in Homeless and Vulnerably Housed Individuals and Its Relationship with Self-Reported Physical and Mental Health Status

Although the association between homelessness and objective indicators of poor health is well-established, little research has focused on the subjective health-related quality of life of homeless and vulnerably housed (HVH) individuals. This study examined the subjective health-related quality of life of HVH individuals, using the Multiple Discrepancies Theory (MDT) Scale for Health of the Quality of Life for Homeless and Hard-to-House Individuals (QoLHHI) Inventory, and its association with self-reported functional health status, as measured by the SF-12, and self-reported physical and mental health conditions in a sample of 100 HVH individuals recruited in Vancouver, Toronto and Ottawa. Our findings indicate that physical and mental health conditions are highly prevalent among HVH individuals and that the SF-12 Physical and Mental Component Summary scores are substantially lower compared to US population norms. The MDT Health items were not statistically significantly associated with physical or mental health conditions and only showed correlations of small to moderate magnitude with the SF-12 Component Summary Scales. These findings suggest that the QoLHHI MDT Scale for Health can provide information about HVH individuals’ subjective health experiences that is different from, and can serve as a valuable complement to, health status information for use in research and evaluation studies, as well as for policy purposes to make informed decisions based on subjective health-related quality of life data from HVH individuals.     

Determinants of adults’ solo living in Canada: a longitudinal perspective

We examine the demographic, socio-economic and socio-cultural factors that underlie solo-living at mid-adult ages. Both individual and community level factors are analysed. The analysis is based on the longitudinal panel data of the Canadian Survey of Labour and Income Dynamics in 1996–2001, 1999–2004, 2002–2008 and 2005–2010, and census data at the Census District level for 1996, 2001 and 2006. A two-level discrete-time survival model is used within a 6 year observational window for each panel. The analysis starts with persons aged 35–59 who were living alone at the outset of a given panel and follows their departure from this status over the following 6 years. For both men and women, the older respondents, those who have been living solo for a longer time, those who are not in the labour force, and those living in apartments, are more likely to continue living alone. Women are more likely to keep their initial one person household status compared to men in general. In particular, women with medium education (non-university post-secondary certification) are more likely to continue living alone, while for men it is those unemployed who are more likely to remain in the solo-living status. Moreover, persons with lower health status are more likely to continue living by themselves, in comparison to those with excellent health status.

     

Measurement models of women’s autonomy using the 1998/1999 India DHS

Research concerning the relationship between female status and demographic behaviour has largely concluded that community level influences are most important, while status and autonomy at the individual level are far less so. This consensus, however, rests on an untested a priori typology of women’s status and tenuous assumptions about the measurement of defined status dimensions on the individual level. To better understand the potential influences of both community and individual elements it is necessary to take a step back and assess the validity of the constructs of autonomy used. This work uses a latent variable measurement modelling framework to test both the dimensionality of women’s status and the appropriateness of using simple additive index scaling in constructing measures of women’s status on the individual level using questions from the Demographic and Health Surveys status-of-women module in India for 1998/1999.     

此心安处是吾乡--流动人口身份认同的区域差异研究

身份认同是流动人口社会融合的重要组成部分,受客观社会环境和主观意愿等多方面因素的影响。利用2014年“流动人口社会融合及心理健康调查”数据,使用线性回归和二元逻辑斯蒂回归方法,分析当前制度区隔与结构排斥下流动人口身份认同的地区差异,文章发现,流动人口身份认同的现状较为复杂,呈现认同意愿“内部有别”与认同结果“人地一致”的特点,即“居留意愿”较低的城市中流动人口的“入籍意愿”较高,“融入于地”状况较好的城市中流动人口“本地人身份认同”度同样较高。从区域分割视角来看,除“入籍意愿”较高外,东部大城市流动人口的身份认同状况不容乐观。同时,受流动跨越行政距离的影响,省内流动人口具有较强的“内部优势”,其身份认同状况优于跨省而来的流动人口。     

The Mediating Role of Perceived Parental Warmth and Parental Punishment in the Psychological Well-Being of Children in Rural China

Research has documented that parenting practices, such as parental warmth and parental punishment, play a mediating role in linking individual (e.g., age, gender) and familial characteristics (e.g., economic status, marital quality) to the psychological well-being of children. However, few studies have validated these connections with respect to the Chinese population, especially those in rural areas of China plagued with unfavorable conditions such as poverty and lack of education. In this study, we investigated whether child (age, gender, and sibship size), and familial characteristics (family wealth, parental education, and marital quality) indirectly contribute to the children??s psychological well-being (as indicated by their self-reported internalizing and externalizing problems) through their perceived parental warmth and parental punishment. Using structural equation modeling, we analyzed data collected from 2,000 children (ages 9?C13) and their parents in rural China. The results reveal significant, indirect relationships from family wealth and marital quality to these children??s externalizing problems through parental warmth and parental punishment. There are age and gender differences in the children??s experiencing internalizing and externalizing problems. Gender differences are also found in their perceived parental warmth and parental punishment. Directions for future research are discussed.
