Hepatitis C in Australia: impact of a mass media campaign.

BACKGROUND: Hepatitis C affects over 200,000 Australians. This study evaluated the impact of a public education campaign about this disease in New South Wales (NSW), Australia. DESIGN: Cohort and independent cross-sectional telephone surveys before and after the campaign. SETTING/PARTICIPANTS: Random population samples of adults in NSW. INTERVENTION: Television, radio and newsprint advertisements, posters and public display boards, public awareness events and media releases, and dissemination of information to healthcare professionals in April 2000. Data were analyzed in 2000 and 2005. MAIN OUTCOME MEASURES: Campaign recall, and knowledge and attitudes concerning hepatitis C. RESULTS: Recall of information about hepatitis C increased between baseline and follow-up, from 11.1% to 45.5% in the independent samples and 11.8% to 65.3% in the cohort. The proportion of people who knew that there was a low risk of disease transmission by kissing, sharing food utensils, or breastfeeding also increased significantly. In the cohort sample, a higher number of correct knowledge responses was associated with reporting exposure to information about hepatitis C after the campaign, postsecondary education, and a greater level of knowledge at baseline. Most people reported supportive attitudes toward people with hepatitis C and to prevention programs addressing this disease, and there was little apparent improvement in these. CONCLUSIONS: This campaign successfully increased public exposure to information about hepatitis C and improved knowledge about the means of transmission of this disease. There is room for further improvements in community understanding about hepatitis C. Mass media campaigns have a valuable role to play in this endeavor.

Comparison of tobacco, alcohol and illegal drug usage among school students in three Pacific Island societies.

BACKGROUND: Many Pacific Island countries are in social and epidemiological transition, but there are little population data about drug and alcohol usage among adolescents in this region. METHODS: Random samples of school students aged 11-17 years completed surveys in three populations: Pohnpei State in the Federated States of Micronesia (n=1495), Tonga (n=2808) and Vanuatu (n=4474). RESULTS: Among 15-year-olds, boys in Tonga reported the highest prevalence of weekly smoking (29%), followed by boys in Pohnpei (17%). Kava use at a potentially harmful level (i.e. daily) was low in all countries. Drunkenness on two or more occasions was much more common among 15-year-old boys in Pohnpei (51%) than same-age youth in the other countries. Marijuana use was most often reported by boys (20%) and girls (20%) in Pohnpei, while solvents had been used most often by boys in Pohnpei (15%), and methylated spirits by boys in Tonga (20%). In all countries bullying of other students was independently related to regular smoking, while bullying behaviour and strong relationships with peers and others outside of the family were related to past drunkenness and use of illegal drugs in Tonga and Vanuatu. CONCLUSIONS: Overall, levels of adolescent substance use were consistently higher in Tonga and Pohnpei than in Vanuatu. These unique data provide a basis for setting priorities and evaluating action to address the health risks posed by substance use in these Pacific Island societies.

Dissemination of physical activity evidence, programs, policies, and surveillance in the international public health arena.

The concepts of dissemination can be applied to the international challenges of promoting physical activity. With the 2004 release of the World Health Organization Global Strategy for Diet and Physical Activity, risk factor reduction and noncommunicable disease control are of global health interest. A six-step framework is proposed for understanding the attributes of successful international dissemination. These include the development of clear and evidence based resources or innovations, defining the target audience, selecting communication channels, engaging decision makers, and developing evaluation frameworks around dissemination. Four case studies to illustrate aspects of the framework are presented: (1) learning from dissemination of effective tobacco control initiatives, (2) the experience of developing global measures and surveillance systems for physical activity, (3) case study of disseminating the Agita program-an effective community wide intervention, and (4) disseminating the World Health Organization Global Strategy on Diet and Physical Activity. Substantial similarities across the experiences described in these case studies suggest underlying common themes for international dissemination, but developing a stronger evidence base for dissemination efforts remains a research priority.

Quantitative methods used in Australian health promotion research: a review of publications from 1992-2002.

ISSUE ADDRESSED: This study examined the use of quantitative methods in Australian health promotion research in order to identify methodological trends and priorities for strengthening the evidence base for health promotion. METHODS: Australian health promotion articles were identified by hand searching publications from 1992-2002 in six journals: Health Promotion Journal of Australia, Australian and New Zealand journal of Public Health, Health Promotion International, Health Education Research, Health Education and Behavior and the American Journal of Health Promotion. The study designs and statistical methods used in articles presenting quantitative research were recorded. RESULTS: 591 (57.7%) of the 1,025 articles used quantitative methods. Cross-sectional designs were used in the majority (54.3%) of studies with pre- and post-test (14.6%) and post-test only (9.5%) the next most common designs. Bivariate statistical methods were used in 45.9% of papers, multivariate methods in 27.1% and simple numbers and proportions in 25.4%. Few studies used higher-level statistical techniques. CONCLUSIONS: While most studies used quantitative methods, the majority were descriptive in nature. The study designs and statistical methods used provided limited scope for demonstrating intervention effects or understanding the determinants of change.

Socio-demographic factors associated with smoking and smoking cessation among 426,344 pregnant women in New South Wales, Australia.

BACKGROUND: This study explores the socio-demographic characteristics of pregnant women who continue to smoke during the pregnancy, and identifies the characteristics of the smokers who were likely to quit smoking during the pregnancy period. METHODS: This was secondary analysis of the New South Wales (NSW) Midwives Data Collection (MDC) 1999-2003, a surveillance system covering all births in NSW public and private hospitals, as well as home births. Bivariate and multiple logistic regression analyses were performed to explore the associations between socio-demographic characteristics and smoking behaviour during pregnancy. RESULTS: Data from 426,344 pregnant women in NSW showed that 17.0% continued to smoke during pregnancy. The smoking rate was higher among teenage mothers, those with an Aboriginal (indigenous) background, and lower among more affluent and overseas-born mothers. This study also found that unbooked confinements, and lack of antenatal care in the first trimester were strongly associated with increased risk of smoking during pregnancy. About 4.0% of the smoking women reported they may quit smoking during their pregnancy. Findings showed that mothers born overseas, of higher socio-economic status, first time mothers and those who attended antenatal care early showed an increased likelihood of smoking cessation during pregnancy. Those who were heavy smokers were less likely to quit during pregnancy. CONCLUSION: Although the prevalence of smoking during pregnancy has been declining, it remains a significant public health concern. Smoking cessation programs should target the population subgroups of women at highest risk of smoking and who are least likely to quit. Effective antismoking interventions could reduce the obstetric and perinatal complications of smoking in pregnancy.

Promoting physical activity in Australian general practices: a randomised trial of health promotion advice versus hypertension management.

A randomised controlled trial was conducted to determine if physicians' advice to promote physical activity to patients was more effective if the advice was tailored to the management of hypertension, compared with more general health promotion advice. Participants included inactive 40- to 70-year-old patients visiting the physicians' during study recruitment period. Physicians provided verbal physical activity advice and written materials, both tailored to either general health promotion messages or specifically as a means for treating or managing hypertension. Seventy-five physicians and 98% (767/780) of screened eligible patients participated in the study. Differences between intervention and control groups self-reported physical activity were assessed over 6 months. Follow-up response rates were 92 and 84% at the 2- and 6-month assessments. There were no consistent, significant differences between groups at the 2- or 6-month assessments. Thus, neither intervention strategy resulted in significant changes in patients self-reported physical activity, regardless of the whether the advice was tailored to hypertension management or general health promotion advice.

Postpartum physical activity and related psychosocial factors among women with recent gestational diabetes mellitus.

OBJECTIVE: In this study, we examined patterns of postpartum physical activity among women with recent gestational diabetes mellitus (GDM) and psychosocial factors related to this behavior that could be addressed in diabetes prevention interventions. RESEARCH DESIGN AND METHODS: A random sample of women who had attended diabetes clinics in Sydney, Australia, in the past 6-24 months for treatment of GDM were surveyed by telephone. Variables measured included physical activity behaviors, self-efficacy, social support, and barriers to participation. RESULTS: Of 226 women who completed the survey (mean age 33.4 years), 26.5% were classified as sedentary, and only 33.6% reported sufficient physical activity as recommended by health authorities. Walking was the most popular physical activity, and most women reported no other moderate- or vigorous-intensity activity. Lack of assistance with child care (49.1%) and insufficient time (37.6%) were the most common barriers to physical activity. The type of social support most often reported was verbal encouragement (39.1%), with more than half of the women never receiving assistance with housework or others exercising with them. Self-efficacy for physical activity was lowest when women were under time pressure or tired. Multivariate analyses showed that sufficient physical activity was associated with high social support (odds ratio 2.5 [95% CI 1.21-3.79]) and high self-efficacy (2.09 [1.06-3.20]). CONCLUSIONS: The prevalence of sufficient physical activity was found to be low and strongly related to social support and self-efficacy. This is an important group to whom diabetes prevention strategies can be targeted.

Access block in NSW hospitals, 1999-2001: does the definition matter?

OBJECTIVES: To estimate the magnitude of access block and its trend over time in New South Wales hospitals, using different definitions of access block, and to explore its association with clinical and non-clinical factors. DESIGN AND SETTING: An epidemiological study using the Emergency Department Information System datasets (1 January 1999 to 31 December 2001) from a sample of 55 NSW hospitals. MAIN OUTCOME MEASURES: Prevalence of access block measured by four different definitions; strength of association between access block, type of hospital, year of presentation, mode and time of arrival, triage category (an indicator of urgency), age and sex. RESULTS: Rates of access block (for all four definitions) increased between 1999 and 2001 by 1%-2% per year. There were increases across all regions of NSW, but urban regions in particular. Patients presenting to Principal Referral hospitals and those who arrived at night were more likely to experience access block. After adjusting for triage category and year of presentation, the mode of arrival, time of arrival, type of hospital, age and sex were significantly associated with access block. CONCLUSIONS: Access block continues to increase across NSW, whatever the definition used. We recommend that hospitals in NSW and Australia move to the use of one standard definition of access block, as our study suggests there is no significant additional information emerging from the use of multiple definitions.

Measurement and prediction of energy expenditure in males during household and garden tasks.

Participation in at least 30 min of moderate intensity activity on most days is assumed to confer health benefits. This study accordingly determined whether the more vigorous household and garden tasks (sweeping, window cleaning, vacuuming and lawn mowing) are performed by middle-aged men at a moderate intensity of 3-6 metabolic equivalents (METs) in the laboratory and at home. Measured energy expenditure during self-perceived moderate-paced walking was used as a marker of exercise intensity. Energy expenditure was also predicted via indirect methods. Thirty-six males [ X (SD): 40.0 (3.3) years; 179.5 (6.9) cm; 83.4 (14.0) kg] were measured for resting metabolic rate (RMR) and oxygen consumption ( VO(2)) during the five activities using the Douglas bag method. Heart rate, respiratory frequency, CSA (Computer Science Applications) movement counts, Borg scale ratings of perceived exertion and Quetelet's index were also recorded as potential predictors of exercise intensity. Except for vacuuming in the laboratory, which was not significantly different from 3.0 METs ( P=0.98), the MET means in the laboratory and home were all significantly greater than 3.0 ( P</=0.006). The sweeping and vacuuming MET means were significantly higher ( P<0.001) at home than in the laboratory, whereas the converse applied for window cleaning and lawn mowing. Measured RMR was significantly lower ( P<0.001) than the 1-MET constant. Estimating METs by fitting random intercept regression models to the data resulted in standard deviations for the "leave-one-out" prediction errors (predicted-measured) of 0.4 and 0.5 METs for the laboratory and home equations, respectively. While the means indicate that all the activities were performed at a moderate intensity, there was great inter-individual variability in energy expenditure. The laboratory and home-based equations predicted with correct classification rates of 89% and 88%, respectively, whether energy expenditure was <3.0 or >/=3.0 METs.

Getting it right: why bother with patient-centred care?

Patient-centred care is about sharing the management of an illness between patient and doctor; it is not new but is increasingly evidence-based, especially for chronic problems such as diabetes, asthma and arthritis. Systematic reviews show that patient-centred care results in increased adherence to management protocols, reduced morbidity and improved quality of life for patients. Key features of the doctor-patient interaction are shared goal setting, written management plans and regular follow-up. Supportive community-based services and programs, combined with healthcare system commitment, are also required to make this approach effective in improving population health.

Ecological and individual predictors of maternal smoking behaviour. Looking beyond individual socioeconomic predictors at the community setting.

The aim of this study is to examine the prevalence of smoking during pregnancy by the individual mother's sociodemographic characteristics and ecological factors at the community level (suburbs). This analysis combined 1996 Australia Census and data on 3424 women attending Well-Baby-Clinics (WBC) between January 1996 and February 1998 within a region in South Western Sydney (SWS), Australia. The prevalence of maternal smoking was 31%. Maternal factors such as marital status, country of birth, education, occupation, socioeconomic status (SES), and types of antenatal care (ANC) were independent risk factors for maternal smoking. Small area analysis revealed suburbs within SWS with high rates of maternal smoking (47-57%). Community level characteristics such as low income, low educational level, young mothers, and unemployment can explain 85.7% of the variation in maternal smoking in SWS. Smoking during pregnancy is recognised as a serious risk factor to the unborn child. The present study draws attention to local community level factors, other than individual SES, which may be important when developing strategies for maternal smoking prevention programs.

Print versus website physical activity programs: a randomized trial.

BACKGROUND: Mediated physical activity interventions can reach large numbers of people at low cost. Programs delivered through the mail that target the stage of motivational readiness have been shown to increase activity. Communication technology (websites and e-mail) might provide a means for delivering similar programs. METHODS: Randomized trial conducted between August and October 2001. Participants included staff at an Australian university (n=655; mean age=43, standard deviation, 10 years). Participants were randomized to either an 8-week, stage-targeted print program (Print) or 8-week, stage-targeted website (Web) program. The main outcome was change in self-reported physical activity. RESULTS: There was no significant increase in total reported physical activity within or between groups when analyzed by intention to treat (F [1,653]=0.41, p=0.52). There was a significant increase in total physical activity reported by the Print participants who were inactive at baseline (t [1,173]=-2.21, p=0.04), and a significant decrease in the average time spent sitting on a weekday in the Web group (t [1,326]=2.2, p=0.03). CONCLUSIONS: There were no differences between the Print and Web program effects on reported physical activity. The Print group demonstrated slightly larger effects and a higher level of recognition of program materials.

Population-based randomized controlled trial of a stage-targeted physical activity intervention.

BACKGROUND: Intervention trials with self-selected participants have shown that mailed stage-targeted print materials can increase participation in physical activity in the short term. We examined the effects of a mailed stage-targeted print intervention designed to promote physical activity, in a random sample of adults living in a regional city. METHOD: Participants (n = 462, 40-60 years of age) were randomly allocated to an intervention (n = 227) or control group (n = 235). Measures included validated 2-week physical activity recall and stage of motivational readiness for physical activity. The intervention consisted of a single mailing of a letter and full-color stage-targeted booklets (specific to precontemplation, contemplation, preparation, and action/maintenance) 1 week postbaseline. Follow-up interviews were conducted at 2 and 6 months postbaseline. RESULTS: After 2 months, participants in the intervention group were significantly more likely to meet the current American College of Sports Medicine/Centers for Disease Control and Prevention recommendation for sufficient physical activity than those in the control group (adjusted odds ratio [OR] = 2.40; 95% confidence interval [CI] = 1.44-3.99). After 6 months, intervention participants who reported receiving and reading the intervention materials were significantly more likely to be meeting the sufficient physical activity criterion compared with the control group (adjusted OR = 2.03; 95% CI = 1.16-3.56). CONCLUSIONS: The stage-targeted print intervention was effective in promoting short-term increases in physical activity and was most effective for participants who recognized and used the materials. This low-cost, generalizable intervention has demonstrated potential as a practical population-based physical activity promotion strategy. Further research is required before widespread dissemination would be justified, as additional strategies may be required to ensure sustained change.

International physical activity questionnaire: 12-country reliability and validity.

BACKGROUND: Physical inactivity is a global concern, but diverse physical activity measures in use prevent international comparisons. The International Physical Activity Questionnaire (IPAQ) was developed as an instrument for cross-national monitoring of physical activity and inactivity. METHODS: Between 1997 and 1998, an International Consensus Group developed four long and four short forms of the IPAQ instruments (administered by telephone interview or self-administration, with two alternate reference periods, either the "last 7 d" or a "usual week" of recalled physical activity). During 2000, 14 centers from 12 countries collected reliability and/or validity data on at least two of the eight IPAQ instruments. Test-retest repeatability was assessed within the same week. Concurrent (inter-method) validity was assessed at the same administration, and criterion IPAQ validity was assessed against the CSA (now MTI) accelerometer. Spearman's correlation coefficients are reported, based on the total reported physical activity. RESULTS: Overall, the IPAQ questionnaires produced repeatable data (Spearman's rho clustered around 0.8), with comparable data from short and long forms. Criterion validity had a median rho of about 0.30, which was comparable to most other self-report validation studies. The "usual week" and "last 7 d" reference periods performed similarly, and the reliability of telephone administration was similar to the self-administered mode. CONCLUSIONS: The IPAQ instruments have acceptable measurement properties, at least as good as other established self-reports. Considering the diverse samples in this study, IPAQ has reasonable measurement properties for monitoring population levels of physical activity among 18- to 65-yr-old adults in diverse settings. The short IPAQ form "last 7 d recall" is recommended for national monitoring and the long form for research requiring more detailed assessment.

Toward a better understanding of the influences on physical activity: the role of determinants, correlates, causal variables, mediators, moderators, and confounders.

BACKGROUND: For research on physical activity interventions to progress systematically, the mechanisms of action must be studied. In doing so, the research methods and their associated concepts and terminology become more complex. It is particularly important to clearly distinguish among determinants, correlates, mediators, moderators, and confounder variables used in physical activity research. This article examines the factors that are correlated with and that may have a causal relationship to physical activity. METHODS AND RESULTS: We propose that the term "correlate" be used, instead of "determinant," to describe statistical associations or correlations between measured variables and physical activity. Studies of the correlates of physical activity are reviewed. The findings of these studies can help to critique existing theories of health behavior change and can provide hypotheses to be tested in intervention studies from which it is possible to draw causal inferences. Mediator, moderator, and confounder variables can act to influence measured changes in physical activity. Intervening causal variables that are necessary to complete a cause-effect pathway between an intervention and physical activity are termed "mediators." The relationship between an intervention and physical activity behaviors may vary for different groups; the strata by which they vary are levels of "moderators" of the relationship. Other factors may distort or affect the observed relationships between program exposure and physical activity, and are known as "confounders." CONCLUSIONS: Consistent use of terms and additional research on mediators and moderators of intervention effects will improve our ability to understand and influence physical activity.

Determining energy expenditure during some household and garden tasks.

PURPOSE: This study: a) calculated the reproducibility (intraclass correlation coefficient, ICC) and precision (technical error of measurement, TEM) for VO2 during moderate paced walking, self-paced sweeping, window cleaning, vacuuming and lawn mowing; b) determined which of the five activities rated >or= 3.0 when exercise intensity was calculated in METs (1 MET or metabolic equivalent = VO2 of 3.5 mL.kg-1.min-1) and multiples of the measured resting metabolic rate (RMR); and c) expanded the limited database on energy expenditure during household and garden activities. METHODS: Twelve men and 12 women (mean +/- SD: 39.3 +/- 3.4 yr; 171.6 +/- 9.6 cm; 81.0 +/- 15.5 kg) were measured for RMR and VO2 during the five activities on two separate days via indirect calorimetry by using the Douglas bag method. RESULTS: The interday ICCs and TEMs for the five activities ranged from 0.81 to 0.97 and from 2.1 to 7.0%, respectively. The means were significantly (P < 0.001) above 3.0 for moderate paced walking (range = 3.3-8.7), sweeping (2.9-6.7), window cleaning (3.0-6.0), vacuuming (2.6-4.4), and lawn mowing (4.9-7.5) when VO2 was divided by measured RMR, but one and five subjects scored below 3.0 for sweeping and vacuuming, respectively. Division of exercise VO2 by the convention of 3.5 mL O2.kg-1.min-1 significantly decreased (P < 0.001) each mean, and lawn mowing (5.0 METs) was the only activity where all subjects scored above 3.0 METs (P < 0.001; 3.8-6.4); nevertheless, the means for walking (3.7 METs), sweeping (3.2 METs), and window cleaning (3.6 METs) were also in the moderate intensity category of 3-6 METs. CONCLUSIONS: These data: a) emphasize that the VO2 during self-paced moderate intensity walking and self-paced household and garden activities can be measured with reproducibility and precision, b) demonstrate that expressing energy expenditure in conventional METs yields lower values than when it is presented as a multiple of measured RMR, c) suggest that all activities except vacuuming are performed at moderate intensity when energy expenditure is expressed in conventional METs, and d) highlight the biological variability in energy expenditure when different people perform the same task.

Correlates of adults' participation in physical activity: review and update.

PURPOSE: To review and update the evidence relating to the personal, social, and environmental factors associated with physical activity (PA) in adults. METHODS: Systematic review of the peer-reviewed literature to identify papers published between 1998 and 2000 with PA (and including exercise and exercise adherence). Qualitative reports or case studies were not included. RESULTS: Thirty-eight new studies were located. Most confirmed the existence of factors already known to be correlates of PA. Changes in status were noted in relation to the influence of marital status, obesity, smoking, lack of time, past exercise behavior, and eight environmental variables. New studies were located which focused on previously understudied population groups such as minorities, middle and older aged adults, and the disabled. CONCLUSION: The newly reported studies tend to take a broader "ecological" approach to understanding the correlates of PA and are more focused on environmental factors. There remains a need to better understand environmental influences and the factors that influence different types of PA. As most of the work in this field still relies on cross-sectional studies, longitudinal and intervention studies will be required if causal relationships are to be inferred.
