Prevalence and risk factors of asthma in First Nations children living on reserves in Canada.

OBJECTIVES: To explore the prevalence and determine the risk factors of asthma in First Nations children aged 0 to 11 years living on reserves in Canada. METHODS: In this cross-sectional study, we considered the data collected as part of the First Nations Regional Health Survey involving 6,657 children living in 238 First Nations communities in the 10 Canadian provinces, the Northwest Territories and the Yukon. RESULTS: The overall prevalence of asthma that has lasted or is expected to last at least six months (ever-asthma) among children living on reserves was 14.6%: a prevalence of 12.9% among 0 to 4 year olds and 15.6% among 5 to 11 year olds. The prevalence of ever-asthma was greater among boys (16.1%) than girls (13.2%). Children from homes with two or more children aged less than 11 years and those who were engaged in daily physical activities were less likely to have a report of ever-asthma. Children from high-income families and smoke-free homes were more likely to have a report of ever-asthma. The association between allergy and ever-asthma was stronger in children with low birth weight. The association between chronic ear infections and ever-asthma was stronger in girls than boys. CONCLUSIONS: The overall prevalence of ever-asthma and factors associated with ever-asthma in First Nations children living on reserves were similar to those reported for off-reserve Aboriginal children and non-Aboriginal Canadian children.

Racial discrimination, post-traumatic stress and prescription drug problems among Aboriginal Canadians.

OBJECTIVES: 1) To examine associations between racial discrimination and drug problems among urban-based Aboriginal adults; and 2) to determine whether these associations are best explained by symptoms of psychological stress, distress or post-traumatic stress disorder (PTSD). METHODS: Data were collected through in-person surveys with a community-based sample of Aboriginal adults (N = 372) living in a mid-sized city in western Canada in 2010. Associations were examined using bootstrapped linear regression models adjusted for confounders, with continuous prescription and illicit drug problem scores as outcomes. Mediation was examined using the cross-products of coefficients method. RESULTS: More than 80% of Aboriginal adults had experienced racial discrimination in the past year, with the majority reporting high levels in that period. Past-year discrimination was a risk factor for PTSD symptoms and prescription drug problems in models adjusted for confounders and other forms of psychological trauma. In mediation models, PTSD symptoms explained the association between discrimination and prescription drug problems; psychological stress and distress did not. PTSD symptoms also explained this association when the covariance between mediators was controlled. The results also indicate that participation in Aboriginal cultural traditions was associated with increased discrimination. CONCLUSIONS: Most efforts to address Aboriginal health inequities in Canada have focused on the role Aboriginal people play in these disparities. The current findings combine with others to call for an expanded focus. Non-Aboriginal Canadians may also play a role in the health inequities observed. The findings of this study suggest efforts to reduce discrimination experienced by Aboriginal adults in cities may reduce PTSD symptomology and prescription drug problems in these populations.

Improving maternal health in Pakistan: toward a deeper understanding of the social determinants of poor women's access to maternal health services.

Evidence suggests national- and community-level interventions are not reaching women living at the economic and social margins of society in Pakistan. We conducted a 10-month qualitative study (May 2010-February 2011) in a village in Punjab, Pakistan. Data were collected using 94 in-depth interviews, 11 focus group discussions, 134 observational sessions, and 5 maternal death case studies. Despite awareness of birth complications and treatment options, poverty and dependence on richer, higher-caste people for cash transfers or loans prevented women from accessing required care. There is a need to end the invisibility of low-caste groups in Pakistani health care policy. Technical improvements in maternal health care services should be supported to counter social and economic marginalization so progress can be made toward Millennium Development Goal 5 in Pakistan.

Illicit and prescription drug problems among urban Aboriginal adults in Canada: the role of traditional culture in protection and resilience.

Illicit and prescription drug use disorders are two to four times more prevalent among Aboriginal peoples in North America than the general population. Research suggests Aboriginal cultural participation may be protective against substance use problems in rural and remote Aboriginal communities. As Aboriginal peoples continue to urbanize rapidly around the globe, the role traditional Aboriginal beliefs and practices may play in reducing or even preventing substance use problems in cities is becoming increasingly relevant, and is the focus of the present study. Mainstream acculturation was also examined. Data were collected via in-person surveys with a community-based sample of Aboriginal adults living in a mid-sized city in western Canada (N = 381) in 2010. Associations were analysed using two sets of bootstrapped linear regression models adjusted for confounders with continuous illicit and prescription drug problem scores as outcomes. Psychological mechanisms that may explain why traditional culture is protective for Aboriginal peoples were examined using the cross-products of coefficients mediation method. The extent to which culture served as a resilience factor was examined via interaction testing. Results indicate Aboriginal enculturation was a protective factor associated with reduced 12-month illicit drug problems and 12-month prescription drug problems among Aboriginal adults in an urban setting. Increased self-esteem partially explained why cultural participation was protective. Cultural participation also promoted resilience by reducing the effects of high school incompletion on drug problems. In contrast, mainstream acculturation was not associated with illicit drug problems and served as a risk factor for prescription drug problems in this urban sample. Findings encourage the growth of programs and services that support Aboriginal peoples who strive to maintain their cultural traditions within cities, and further studies that examine how Aboriginal cultural practices and beliefs may promote and protect Aboriginal health in an urban environment.

Critical realism: a practical ontology to explain the complexities of smoking and tobacco control in different resource settings.

BACKGROUND: This paper presents critical realism (CR) as an innovative system for research in tobacco prevention and control. CR argues that underlying mechanisms are considered and explored to ensure effective implementation of any program/policy or intervention. Any intervention or program/policy that is transposed from one country to another or one setting to another is complex. METHODS: The research was undertaken and analyzed through a critical ethnography lens using CR as a philosophical underpinning. The study relied upon the following components: original fieldwork in Nigeria including participant observation of smokers, in-depth interviews and focus groups with smokers, and in-depth interviews with health professionals working in the area of tobacco control in Nigeria. RESULTS: Findings from this small ethnographic study in Nigeria, suggest that Critical Realism holds promise for addressing underlying mechanism that links complex influences on smoking. CONCLUSION: This paper argues that understanding the underlying mechanisms associated with smoking in different societies will enable a platform for effective implementation of tobacco control policies that work in various settings.

Racial discrimination, post traumatic stress, and gambling problems among urban Aboriginal adults in Canada.

Little is known about risk factors for problem gambling (PG) within the rapidly growing urban Aboriginal population in North America. Racial discrimination may be an important risk factor for PG given documented associations between racism and other forms of addictive behaviour. This study examined associations between racial discrimination and problem gambling among urban Aboriginal adults, and the extent to which this link was mediated by post traumatic stress. Data were collected via in-person surveys with a community-based sample of Aboriginal adults living in a mid-sized city in western Canada (N = 381) in 2010. Results indicate more than 80 % of respondents experienced discrimination due to Aboriginal race in the past year, with the majority reporting high levels of racism in that time period. Past year racial discrimination was a risk factor for 12-month problem gambling, gambling to escape, and post traumatic stress disorder (PTSD) symptoms in bootstrapped regression models adjusted for confounders and other forms of social trauma. Elevated PTSD symptoms among those experiencing high levels of racism partially explained the association between racism and the use of gambling to escape in statistical models. These findings are the first to suggest racial discrimination may be an important social determinant of problem gambling for Aboriginal peoples. Gambling may be a coping response that some Aboriginal adults use to escape the negative emotions associated with racist experiences. Results support the development of policies to reduce racism directed at Aboriginal peoples in urban areas, and enhanced services to help Aboriginal peoples cope with racist events.

Racial discrimination experienced by aboriginal university students in Canada.

OBJECTIVES: Racial discrimination is an established life course social determinant of health associated with adverse psychological outcomes among minority populations. However, little is known about the extent to which Aboriginal people in Canada may experience racial discrimination and consequent adverse psychological effects. This study sought to measure the extent to which Aboriginal university students living in an urban area of Canada experienced racism, to triangulate this evidence with US data and qualitative findings, and to examine the impact of these experiences on mental health. METHODS: Data for this mixed method study were collected via in-person surveys with a volunteer sample of Aboriginal university students (n = 60) living in a mid-sized city in central Canada in 2008-2009. RESULTS: Results indicate Aboriginal university students experienced more frequent racism across a greater number of life situations than African- and Latino-American adults in the United States. Student reactions to these experiences were symptomatic of what has been termed racial battle fatigue in the United States. Students who considered themselves traditional or cultural Aboriginal persons were significantly more likely to experience discrimination. CONCLUSIONS: Results underline the need for policies aimed at reducing racism directed at Aboriginal people in urban areas and the growth of services to help Aboriginal people cope with these experiences. Results highlight the need for further research to determine the potential pathogenic consequences of racial discrimination for Aboriginal people in Canada.

Addressing disparities in maternal health care in Pakistan: gender, class and exclusion.

BACKGROUND: After more than two decades of the Safe Motherhood Initiative and Millennium Development Goals aimed at reducing maternal mortality, women continue to die in childbirth at unacceptably high rates in Pakistan. While an extensive literature describes various programmatic strategies, it neglects the rigorous analysis of the reasons these strategies have been unsuccessful, especially for women living at the economic and social margins of society. A critical gap in current knowledge is a detailed understanding of the root causes of disparities in maternal health care, and in particular, how gender and class influence policy formulation and the design and delivery of maternal health care services. Taking Pakistan as a case study, this research builds upon two distinct yet interlinked conceptual approaches to understanding the phenomenon of inequity in access to maternal health care: social exclusion and health systems as social institutions. METHODS/DESIGN: This four year project consists of two interrelated modules that focus on two distinct groups of participants: (1) poor, disadvantaged women and men and (2) policy makers, program managers and health service providers. Module one will employ critical ethnography to understand the key axes of social exclusion as related to gender, class and zaat and how they affect women's experiences of using maternal health care. Through health care setting observations, interviews and document review, Module two will assess policy design and delivery of maternal health services. DISCUSSION: This research will provide theoretical advances to enhance understanding of the power dynamics of gender and class that may underlie poor women's marginalization from health care systems in Pakistan. It will also provide empirical evidence to support formulation of maternal health care policies and health care system practices aimed at reducing disparities in maternal health care in Pakistan. Lastly, it will enhance inter-disciplinary research capacity in the emerging field of social exclusion and maternal health and help reduce social inequities and achieve the Millennium Development Goal No. 5.

Enculturation and alcohol use problems among aboriginal university students.

OBJECTIVE: To examine associations between aboriginal enculturation, Canadian acculturation, and alcohol problems among aboriginal university students living in an urban area in Canada. METHODS: Data for this mixed methods study were collected through in-person surveys with a convenience sample of aboriginal university students (n = 60) in 2008/2009. RESULTS: Students evidenced high levels of aboriginal enculturation and Canadian acculturation. aboriginal enculturation was significantly associated with reduced alcohol problems for aboriginal university students. There was no association between Canadian acculturation and alcohol problems. Qualitative findings suggest aboriginal cultural practices helped students cope with problems in their daily lives and provided them with both personal and social rewards. CONCLUSIONS: This study found aboriginal enculturation was significantly associated with reduced alcohol problems among aboriginal university students. Results support the growth of programs and services that encourage aboriginal students to maintain their cultural identity within the university setting.

Maternal deaths in Pakistan: intersection of gender, caste, and social exclusion.

BACKGROUND: A key aim of countries with high maternal mortality rates is to increase availability of competent maternal health care during pregnancy and childbirth. Yet, despite significant investment, countries with the highest burdens have not reduced their rates to the expected levels. We argue, taking Pakistan as a case study, that improving physical availability of services is necessary but not sufficient for reducing maternal mortality because gender inequities interact with caste and poverty to socially exclude certain groups of women from health services that are otherwise physically available. METHODS: Using a critical ethnographic approach, two case studies of women who died during childbirth were pieced together from information gathered during the first six months of fieldwork in a village in Northern Punjab, Pakistan. FINDINGS: Shida did not receive the necessary medical care because her heavily indebted family could not afford it. Zainab, a victim of domestic violence, did not receive any medical care because her martial family could not afford it, nor did they think she deserved it. Both women belonged to lower caste households, which are materially poor households and socially constructed as inferior. CONCLUSIONS: The stories of Shida and Zainab illustrate how a rigidly structured caste hierarchy, the gendered devaluing of females, and the reinforced lack of control that many impoverished women experience conspire to keep women from lifesaving health services that are physically available and should be at their disposal.

Adults' use of health services in the year before death by suicide in Alberta.

BACKGROUND: The suicide rate in Alberta is consistently above the Canadian average. Health care use profiles of those who die by suicide in Alberta are currently unknown. DATA AND METHODS: Death records were selected for people aged 25 to 64 with suicide coded as the underlying cause of death from April 1, 2003 to March 31, 2006. The death records were linked to administrative records pertaining to physician visits, emergency department visits, inpatient hospital separations, and community mental health visits. The control group was the Alberta population aged 25 to 64 who did not die by suicide. Frequency estimates were produced to determine the characteristics of the study population. Odds ratios relating to demographics, exposure to health care services, and case-control status were estimated with logistic regression. RESULTS: Almost 90% of suicides had a health service in the year before their death. Suicides averaged 16.6 visits per person, compared with 7.7 visits for non-suicides. Much of the health service use among people who died by suicide appears to have been driven by mental disorders. INTERPRETATION: Information about health service delivery to those who die by suicide can guide prevention and intervention efforts.

The association of television viewing with snacking behavior and body weight of young adults.

PURPOSE: Investigate whether TV viewing and recognition of snack food advertisements were associated with snack food consumption and the odds of being overweight or obese. DESIGN: Cross-sectional internet-based survey. SETTING: University of Alberta, Edmonton, Canada. SUBJECTS: Undergraduate university students aged 18 to 25 years (N = 613). MEASURES: Self-reported TV viewing, energy-dense snack consumption, snacking while viewing TV, and body weight. ANALYSIS: Hypothesis testing was completed using multiple analysis of variance, analysis of covariance, and logistic regression. RESULTS: Students reporting medium or high TV viewership snacked more frequently while watching TV and recognized more advertising than students who were considered low viewers. High viewers also reported more consumption of energy-dense snacks than low viewers. Snacking frequency appeared to be related to TV viewing and place of residence, but the association between snacking frequency and TV viewing was not accounted for by advertising. Conversely, the association between TV viewing and consumption of energy-dense snacks was accounted for by advertising recognition. Finally, male students (odds ratio [OR], 2.78; 99% confidence interval [CI], 1.68-4.59) and medium (OR, 3.11; 99% CI, 1.37-7.08) and high (OR, 5.47; 99% CI, 1.97-15.16) TVviewers had higher odds of being overweight or obese. CONCLUSIONS: Associations were found among TV viewing, energy-dense snack consumption, and snacking behavior, and between TV viewing and body weight status.

Adolescent reproductive health in Uganda: issues related to access and quality of care.

UNLABELLED: Adolescent health in Kabarole district, Uganda, is seriously jeopardized by both high teenage pregnancy rates and high rates of sexually transmitted diseases, including HIV infection. OBJECTIVES: To elucidate views, perceptions and attitudes of key informants who are involved in the delivery of reproductive health services to adolescents. STUDY GROUP: Four managers of youth-related nongovernmental organizations, two government nurses, and four youth leaders. METHODS: Qualitative study with content analysis using in-depth interviews. RESULTS: Participants agreed that reproductive health services in Kabarole district are not adolescent friendly. Most often, lack of privacy and confidentiality for the adolescents attending a health unit was cited as one important reason. Other factors contributing to a less adolescent friendly service environment were inconvenience of services including the fragmentation of different service components and lack of specific traIning for health workers on how to relate appropriately to adolescents. Also noted was that several participants had a negative attitude toward the sexual activity of adolescents. Suggestions for service improvement were limited to training of health workers and increased support for the infrastructure. CONCLUSIONS: Reproductive health services for adolescents in Kabarole district could be strengthened by improving the privacy and confidentiality of services. Health workers must also be trained in counseling and in treating adolescents in a youth-appropriate and high quality fashion. Staff attitudes must also be addressed.

Knowledge of and perceptions about sexually transmitted diseases and pregnancy: a qualitative study among adolescent students in Uganda.

This article reports the findings of a qualitative research study carried out in Kabarole district, western Uganda. Knowledge of and perceptions about HIV/AIDS and pregnancy and how both relate to one another were elucidated from eight focus-group discussions with 38 female and 32 male secondary students from four different schools. Widespread misinformation and misconceptions about contraceptives still exist as previously found in this area. There was a serious gap in knowledge and understanding of 'dual protection' against sexually transmitted diseases, including HIV/AIDS, and against pregnancy. Fertility was very highly valued, and many girls stated that they would want a child even if they were HIV-positive. Responses of girls showed that they were quite assertive in making decisions to use contraceptives. The reasons for students not being able to understand the interconnectedness of sexually transmitted diseases and pregnancy may lie in the fragmented fashion in which relevant health education is delivered through two separate programmes.

Effectiveness of an HIV prevention program for secondary school students in Mongolia.

PURPOSE: To evaluate the effectiveness of a 3-year human immunodeficiency virus (HIV) prevention program for adolescents attending secondary school in Mongolia. METHODS: Comparisons of knowledge, attitudes, self-efficacy and safe sex practices of grade 10 students from schools with a peer education prevention program to grade 10 students from schools without the intervention. Peer education programs were launched in 2000 across Mongolia. In 2004, survey data was collected among 720 randomly selected students from eight schools with the peer education prevention program and compared with those of 647 students from eight schools without this intervention. Data was collected in Ulaanbaatar and three Mongolian provinces and analyzed using multilevel regression methods. RESULTS: Students of schools with the program were statistically significantly more knowledgeable, had less traditional attitudes, and had greater awareness of their self-efficacy in regards to HIV and sexual health. Students from schools with the peer education program were more likely to practice safe sex, though the difference was not statistically significant. However, safe sex practice was found to be statistically significantly safer in a subset of schools that had small teams of peer educators. CONCLUSION: Adolescents in Mongolia are sexually active and at risk for infection with HIV and other STIs. Peer education programs, particularly those that are managed by small teams, appear effective and should be implemented more broadly.

Care burden and self-reported health status of informal women caregivers of HIV/AIDS patients in Kinshasa, Democratic Republic of Congo.

We conducted a cross-sectional study on women who were caregivers of HIV/AIDS-affected spouses in Bumbu in Kinshasa, Democratic Republic of Congo. The sample consisted of 80 women randomly selected from a client visitation list of the home-based care program for AIDS patients. A semi-structured questionnaire was applied. A self-reported health status was calculated with five items from the questionnaire. The self-reported health status score of participants indicated poor health. The study highlights the great burden on caregivers in sub-Saharan Africa.

Family caregiving for AIDS patients in the Democratic Republic of Congo.

We conducted a qualitative study of women who were caregivers for HIV/AIDS-affected spouses in Bumbu Zone, Kinshasa, Democratic Republic of Congo in 2003. Twelve caregiving women, six home-based care workers and five key informants were interviewed via focus group discussions. Most women reported huge problems in providing care to their spouses due to psychological, social and economic factors. The secrecy around HIV/AIDS issues and care was a significant theme in the findings. The self-reported health status of the caregivers indicated poor health.

Nutritional status of young children in AIDS-affected households and controls in Uganda.

This study conducted in Uganda assessed the nutritional status of young children and their disease history in the 3-month period before the study. Two groups of children were randomly selected: the first group consisted of 105 children living in homes where a family member fell sick of AIDS, whereas the second group consisted of 100 children who were living in homes where nobody was affected by AIDS. Acute malnutrition (wasting) was rare. There was no difference in the severity of stunting in the two groups (Z scores, -2.1 versus -2.2, P = 0.70). In those children living in AIDS-affected homes, disease episodes were longer (15.7 versus 11.3 days, P = 0.014), but the frequency of disease occurrence was similar in both groups. Fifty-five percent of all children suffered from moderate to severe malnutrition (stunting). The high stunting rate in early childhood suggests a public nutritional intervention program is recommended.

Family caregiving for AIDS patients in the Democratic Republic of Congo.

We conducted a qualitative study of women who were caregivers for HIV/AIDS-affected spouses in Bumbu Zone, Kinshasa, Democratic Republic of Congo in 2003. Twelve caregiving women, six home/based care workers and five key informants were interviewed via focus group discussions. Most women reported huge problems in providing care to their spouses due to psychological, social and economic factors. The secrecy around HIV/AIDS issues and care was a significant theme in the findings. The self-reported health status of the caregivers indicated poor health.

Exploring the social and cultural context of sexual health for young people in Mongolia: implications for health promotion.

Recent political, economic, and cultural changes in Mongolia make its large proportion of young people vulnerable to HIV infection. While there had been only two clinical cases of HIV in Mongolia by the year 2000, the incidence of sexually transmitted infections (STIs) is on the rise, especially among people aged 15-24. Little is known about the social and cultural context in which the sexual knowledge, attitudes, and behaviour of Mongolian young people are created and negotiated. This context must be better understood in order to promote safer sex practices. This study employed qualitative research methods to explore and describe the social and cultural context in which sexual behaviour is negotiated among secondary school students in Ulaanbaatar, Mongolia. Students and teachers from two schools in Ulaanbaatar and health professionals were selected by purposeful sampling to participate in six semi-structured focus group interviews in autumn 2000. Thematic content analysis was conducted on the focus group transcripts. Seven themes were extracted including embarrassment, lack of knowledge, concepts of sex, perceptions of condoms, gender roles, peer norms, and the influence of drinking on sexual activity. Results presented are the first description of the social and cultural context of sexual health and highlight the combined impact of these themes on safer sex practices in Mongolia. These findings are not generalizable, but their agreement with the Mongolian and the international literature indicates that they may be transferable. Implications for STI and HIV/AIDS prevention efforts and further research in Mongolia are discussed.
