Community-based cultural predictors of Pap smear screening in Nova Scotia

BACKGROUND: Pap smear screening is effective in reducing the incidence of cervical cancer. However, some subgroups of women are less likely to be screened than others. Since Canadian provincial health databases do not contain data fields identifying ethnicity or language, analyses employing these variables are typically not available. This paper overcomes this problem by using community- rather than person-based measures. Associations with having had a recent Pap smear are reported by community income, language, ethnic group, and urban/rural status, as well as the woman's age. METHODS: The provincial Health Card Number and Cytology Registries were linked to ascertain the screening status of women in mainland Nova Scotia and Cape Breton. Postal codes were linked to census enumeration areas and then to Statistics Canada census data to create community-based cultural measures for each woman. RESULTS: Women in mainland Nova Scotia were more likely to have had a recent Pap smear (Odds Ratio (OR)=1.36; 95% Confidence Interval (CI):1.33-1.39). Women living in low income (OR=1.19; CI:1.15-1.22), Aboriginal (OR=1.60; CI:1.46-1.76), mixed Black (OR=1.25; CI:1.19-1.30) and rural (OR=1.09; CI:1.07-1.11) communities and who were older were less likely to have had a recent Pap smear. DISCUSSION: These findings were not unexpected. In the United States and elsewhere, associations between Pap screening status and women with low income, rural residence, Aboriginal and Black heritage have been reported using person-based methods. Our findings demonstrate a method of providing measures of ethnicity and language that should be considered for use in Canadian studies of service utilization, disease status, and well-being.     

An incremental cost analysis of telehealth in Nova Scotia from a societal perspective

We examined the costs of telehealth in Nova Scotia from a societal perspective. The clinical outcomes of telepsychiatry and teledermatology services were assumed to be similar to those for conventional face-to-face consultations. Cost information was obtained from the Nova Scotia Department of Health, the Canadian Institute for Health Information, and questionnaires to patients, physicians and telehealth coordinators. There were 215 questionnaires completed by patients, 135 by specialist physicians and eight by telehealth coordinators. Patient costs for a face-to-face consultation ranged from $240 to $1048 (all costs in Canadian dollars), whereas patient costs for telehealth were lower, from $17 to $70. However, from a societal perspective, the overall cost of providing face-to-face services was lower than for telehealth: the total costs for face-to-face services ranged from $325 to $1133, while the total costs for telehealth services ranged from $1736 to $28,084. A threshold analysis showed that, above a certain patient workload, telehealth services would be more cost-effective than face-to-face services from a societal perspective. This workload is attainable in Nova Scotia.     

Older male sexual partner as a marker for sexual risk-taking in adolescent females in Nova Scotia

PURPOSE: To examine age differences between Nova Scotia women aged 15-19 and their male sexual partners, and to determine if those adolescents with older partners were more likely to have engaged in sexual risk-taking behaviours. METHODS: A cross-sectional survey (response rate=91%) administered in May 2003 assessed the following sexual risk behaviours: (a) not using condom/hormonal contraception at last vaginal intercourse; (b) having unplanned vaginal intercourse while using alcohol or drugs; (c) having more than one partner in the previous year; (d) vaginal intercourse before age 15; and (e) ever having anal intercourse. Univariate analysis was carried out to determine associations of sexual risk behaviours with partner age difference. Logistic regression was then used to examine behaviours associated with partner age (p < 0.15) in univariate analysis. RESULTS: Of the young women surveyed, 520 (47.7%) had had vaginal intercourse in the previous year; 515 of these provided information on their last partner's age. Over 10% had partners four or more years older. In multivariate analysis, having a partner > or =4 years older was associated with not using a condom at last intercourse (OR 2.15; 95% Cl 1.10-4.20), having more than one partner in the previous year (OR 21.9; 95% Cl 1.13-4.28) and having unplanned vaginal intercourse while using alcohol or drugs (OR 2.66; 95% Cl 1.34-5.28). CONCLUSIONS: A significant number of female adolescents have older male sexual partners, and such relationships are markers for high-risk sexual behaviours. Partner age is an important consideration for health professionals providing sexual health advice to young women.     

Experiences of a state-sponsored notification and screening program for asbestos workers

Worker notification can involve a broad range of activities including medical screening, personal and mass communications, cohort identification and tracing, and even litigation. The inclusion or exclusion of various supporting activities in a worker notification program may pose significant medical, public health, financial, logistical, and even legal implications for targeted individuals as well as for the agencies involved. This report describes some experiences in a state-sponsored notification and screening program of approximately 4,500 asbestos workers in Minnesota. In this program, a variety of factors led to the decision to provide medical screening to 1,101 workers and 451 spouses. It is anticipated that another 3,400 workers will be notified but not screened. A follow-up survey of notified workers showed overwhelming support for this program. It is estimated that this program will cost more than $650,000 by its completion. The decision to institute medical screening and other support activities should be made with careful consideration of the diverse implications of these activities to the individuals, communities, and agencies involved. © 1993 Wiley-Liss, Inc.     

Defining and operationalizing capacity for heart health promotion in Nova Scotia, Canada

This paper presents an operational definition of capacity building for heart health promotion, instruments developed to measure heart health capacity, and baseline results of capacity for 20 organizations. Qualitative and quantitative research methods were used to collect data. Three instruments were developed to measure organizational capacity for heart health promotion: a survey of community agencies involved in heart health, a questionnaire of organizational practices supportive of heart health promotion, and an interview guide that focused on factors influencing heart health promotion. These instruments proved effective and informed the development of a comprehensive framework for heart health promotion.     

Dietary iron as a risk factor for myocardial infarction. Public health considerations for Nova Scotia

BACKGROUND: Epidemiological and experimental studies have suggested that high levels of dietary iron and hemeiron can lead to myocardial injury. Lean meat, a primary source of iron and hemeiron, is promoted because it is lower in fat and cholesterol. Does lean meat put us at risk for myocardial infarction, and should we reconsider its promotion? METHODS: We analyzed the importance of dietary iron and hemeiron as a risk for myocardial infarction among 2,198 Nova Scotians who participated in a nutrition survey and who were followed for eight years, using logistic regression. RESULTS: Acute myocardial infarction incidents occurred in 94 (4.3%) participants. We found no increased risk for myocardial infarction associated with high intake of iron and hemeiron. CONCLUSIONS: Based on Nova Scotian data showing no increased risk for myocardial infarction with high intake of iron and hemeiron, there is no need for immediate reconsideration of promotion of lean meat.     

Seroepidemiology of Q fever among domestic animals in Nova Scotia.

We used the indirect microimmunofluorescence test to determine the presence of antibodies in sheep, cattle, goat, cat, and dog sera to phase I and II Coxiella burnetii antigens in Nova Scotia. Only 6.7 per cent of the 329 sheep tested had antibodies to phase II antigen and none had antibodies to phase I. Of 29 goats tested, 7 per cent and 3.5 per cent had antibodies to phase II and phase I antigens, respectively. In contrast, 23.8 per cent of the 214 cattle tested had antibodies to phase II antigen, and 24.2 per cent had antibodies to phase I antigen; 24.1 per cent of 216 cats tested had antibodies to phase II antigen and 6 per cent had antibodies to phase I antigen. None of the 447 dogs tested had antibodies detected. We conclude that cattle and cats may be reservoirs for human Q fever in Nova Scotia.     

Effect of Inservice Training on Implementation of a Health Curriculum in Nova Scotia, Canada

The effect of different types of inservice training on the degree of implementation of a fourth grade health curriculum in Nova Scotia, Canada, was investigated. Using a quasiexperimental, nonequivalent control group design with posttest only, teachers (N = 41) were assigned to one trial group and two comparison groups. The distal comparison group received no inservice training, the local comparison group received a single session, and the trial group received ongoing, inservice training. The Health Program Component Checklist developed for this study was used to measure implementation. Data were collected by personal interview. Based on the Mann-Whitney U test, a significantly greater degree of implementation occurred in the trial group than in the proximal comparison group, but not the distal comparison group.     

Dietary intake and risk factors for poor diet quality among children in Nova Scotia

OBJECTIVE: Public health policies promote healthy nutrition but evaluations of children's adherence to dietary recommendations and studies of risk factors of poor nutrition are scarce, despite the importance of diet for the temporal increase in the prevalence of childhood obesity. Here we examine dietary intake and risk factors for poor diet quality among children in Nova Scotia to provide direction for health policies and prevention initiatives. METHODS: In 2003, we surveyed 5,200 grade five students from 282 public schools in Nova Scotia, as well as their parents. We assessed students' dietary intake (Harvard's Youth Adolescent Food Frequency Questionnaire) and compared this with Canadian food group and nutrient recommendations. We summarized diet quality using the Diet Quality Index International, and used multilevel regression methods to evaluate potential child, parental and school risk factors for poor diet quality. RESULTS: In Nova Scotia, 42.3% of children did not meet recommendations for milk products nor did they meet recommendations for the food groups 'Vegetables and fruit' (49.9%), 'Grain products' (54.4%) and 'Meat and alternatives' (73.7%). Children adequately met nutrient requirements with the exception of calcium and fibre, of which intakes were low, and dietary fat and sodium, of which intakes were high. Skipping meals and purchasing meals at school or fast-food restaurants were statistically significant determinants of poor diet. Parents' assessment of their own eating habits was positively associated with the quality of their children's diets. INTERPRETATION: Dietary intake among children in Nova Scotia is relatively poor. Explicit public health policies and prevention initiatives targeting children, their parents and schools may improve diet quality and prevent obesity.     

Socioeconomic differences in the use of physician services in Nova Scotia.

OBJECTIVES: Socioeconomic differences in use of physician services in Nova Scotia, Canada were examined. METHODS: The study was based on survey data, containing information on socioeconomic status, linked to physician claims data. Socioeconomic differences in use of physician services were estimated, adjusted for age, sex, and region of residence. RESULTS: Large socioeconomic differences were observed in the use of physician services, with use inversely related to both household income and education. These differences remained after adjustment for age, sex, and region. CONCLUSIONS: Use of physician services is inversely associated with socioeconomic status.     

Development of an interactive computer program for advance care planning

Objective  To describe the development of an innovative, multi-media decision aid for advance care planning.
Background  Advance care planning is an important way for people to articulate their wishes for medical care when they are not able to speak for themselves. Living wills and other types of advance directives are the most commonly used tools for advance care planning, but have been criticized for being vague, difficult to interpret, and inconsistent with individuals' core beliefs and values.
Results  We developed a multimedia, computer-based decision aid for advance care planning ( 'Making Your Wishes Known: Planning Your Medical Future' ) to overcome many of the limitations of standard advance directive forms. This computer program guides individuals through the process of advance care planning, and unlike standard advance directives, provides tailored education, values clarification exercises, and a decision-making tool that translates an individual's values and preferences into a specific medical plan that can be implemented by a health-care team. Pilot testing with 50 adult volunteers recruited from an outpatient primary care clinic showed high levels of satisfaction with the program. Further pilot testing with 34 cancer patients indicated that the program was perceived to be highly accurate at representing patients' wishes.
Conclusions  This paper describes the development of an innovative decision aid for advance care planning that was designed to overcome common problems with standard advance directives. Preliminary testing suggests that it is acceptable to users and is accurate.
