Prevalence, circumstances and consequences of falls among community-dwelling older people: results of the 2009 NSW Falls Prevention Baseline Survey

AIM To describe the prevalence, circumstances and consequences of falls among community-dwelling older people in NSW using data from the 2009 NSW Falls Prevention Baseline Survey. METHODS Telephone interviews with a random sample of 5681 NSW residents aged 65 years and over were conducted in 2009. RESULTS Of those surveyed, 25.6% reported falling in the last year. Of those who fell, 61.2% fell once, 21.4% fell twice, 7.8% fell three times, and 9.5% fell four or more times in the last year. Sixty-six percent of those who fell in the last year were injured and 20.0% visited a hospital as a result of a fall. The most common injuries were cuts, grazes or bruises (71.0%) and sprains or strains (9.9%). CONCLUSION The findings of this survey are consistent with previous findings in the published fall injury prevention literature. The results from the survey will assist in the design of community oriented fall injury prevention strategies and will form the baseline measure for the evaluation of the impact of these strategies in NSW.

Pandemic influenza in Australia: Using telephone surveys to measure perceptions of threat and willingness to comply

BackgroundBaseline data is necessary for monitoring how a population perceives the threat of pandemic influenza, and perceives how it would behave in the event of pandemic influenza. Our aim was to develop a module of questions for use in telephone health surveys on perceptions of threat of pandemic influenza, and on preparedness to comply with specific public health behaviours in the event of pandemic influenza.MethodsA module of questions was developed and field tested on 192 adults using the New South Wales Department of Healths in-house Computer Assisted Telephone Interviewing (CATI) facility. The questions were then modified and re field tested on 202 adults. The module was then incorporated into the New South Wales Population Health Survey in the first quarter of 2007. A representative sample of 2,081 adults completed the module. Their responses were weighted against the state population.ResultsThe reliability of the questions was acceptable with kappa ranging between 0.25 and 0.51. Overall 14.9% of the state population thought pandemic influenza was very or extremely likely to occur; 45.5% were very or extremely concerned that they or their family would be affected by pandemic influenza if it occurred; and 23.8% had made some level of change to the way they live their life because of the possibility of pandemic influenza. In the event of pandemic influenza, the majority of the population were willing to: be vaccinated (75.4%), be isolated (70.2%), and wear a face mask (59.9%). People with higher levels of threat perception are significantly more likely to be willing to comply with specific public health behaviours.ConclusionWhile only 14.9% of the state population thought pandemic influenza was very or extremely likely to occur, a significantly higher proportion were concerned for self and family should a pandemic actually occur. The baseline data collected in this survey will be useful for monitoring changes over time in the populations perceptions of threat, and preparedness to comply with specific public health behaviours.

Inclusion of mobile phone numbers into an ongoing population health survey in New South Wales, Australia: design, methods, call outcomes, costs and sample representativeness

BackgroundIn Australia telephone surveys have been the method of choice for ongoing jurisdictional population health surveys. Although it was estimated in 2011 that nearly 20% of the Australian population were mobile-only phone users, the inclusion of mobile phone numbers into these existing landline population health surveys has not occurred. This paper describes the methods used for the inclusion of mobile phone numbers into an existing ongoing landline random digit dialling (RDD) health survey in an Australian state, the New South Wales Population Health Survey (NSWPHS). This paper also compares the call outcomes, costs and the representativeness of the resultant sample to that of the previous landline sample.MethodsAfter examining several mobile phone pilot studies conducted in Australia and possible sample designs (screening dual-frame and overlapping dual-frame), mobile phone numbers were included into the NSWPHS using an overlapping dual-frame design. Data collection was consistent, where possible, with the previous years’ landline RDD phone surveys and between frames. Survey operational data for the frames were compared and combined. Demographic information from the interview data for mobile-only phone users, both, and total were compared to the landline frame using χ2 tests. Demographic information for each frame, landline and the mobile-only (equivalent to a screening dual frame design), and the frames combined (with appropriate overlap adjustment) were compared to the NSW demographic profile from the 2011 census using χ2 tests.ResultsIn the first quarter of 2012, 3395 interviews were completed with 2171 respondents (63.9%) from the landline frame (17.6% landline only) and 1224 (36.1%) from the mobile frame (25.8% mobile only). Overall combined response, contact and cooperation rates were 33.1%, 65.1% and 72.2% respectively. As expected from previous research, the demographic profile of the mobile-only phone respondents differed most (more that were young, males, Aboriginal and Torres Strait Islanders, overseas born and single) compared to the landline frame responders. The profile of respondents from the two frames combined, with overlap adjustment, was most similar to the latest New South Wales (NSW) population profile.ConclusionsThe inclusion of the mobile phone numbers, through an overlapping dual-frame design, did not impact negatively on response rates or data collection, and although costing more the design was still cost-effective because of the additional interviews that were conducted with young people, Aboriginal and Torres Strait Islanders and people who were born overseas resulting in a more representative overall sample.

Population risk perceptions of global warming in Australia

INTRODUCTION According to the World Health Organisation (WHO), global warming has the potential to dramatically disrupt some of lifes essential requirements for health, water, air and food. Understanding how Australians perceive the risk of global warming is essential for climate change policy and planning. The aim of this study was to determine the prevalence of, and socio-demographic factors associated with, high levels of perceived likelihood that global warming would worsen, concern for self and family and reported behaviour changes. METHODS A module of questions on global warming was incorporated into the New South Wales Population Health Survey in the second quarter of 2007. This Computer Assisted Telephone Interview (CATI) was completed by a representative sample of 2004 adults. The weighted sample was comparable to the Australian population. Bivariate and multivariate statistical analyses were conducted to examine the socio-demographic and general health factors. RESULTS Overall 62.1% perceived that global warming was likely to worsen; 56.3% were very or extremely concerned that they or their family would be directly affected by global warming; and 77.6% stated that they had made some level of change to the way they lived their lives, because of the possibility of global warming. After controlling for confounding factors, multivariate analyses revealed that those with high levels of psychological distress were 2.17 (Adjusted Odds Ratio (AOR)=2.17; CI: 1.16-4.03; P=0.015) times more likely to be concerned about global warming than those with low psychological distress levels. Those with a University degree or equivalent and those who lived in urban areas were significantly more likely to think that global warming would worsen compared to those without a University degree or equivalent and those who lived in the rural areas. Females were significantly (AOR=1.69; CI: 1.23-2.33; P=0.001) more likely to report they had made changes to the way they lived their lives due to the risk of global warming. CONCLUSIONS A high proportion of respondents reported that they perceived that global warming would worsen, were concerned that it would affect them and their families and had already made changes in their lives because of it. These findings support a readiness in the population to deal with global warming. Future research and programs are needed to investigate population-level strategies for future action.

Epidemiology of influenza-like illness during Pandemic (H1N1) 2009, New South Wales, Australia.

To rapidly describe the epidemiology of influenza-like illness (ILI) during the 2009 winter epidemic of pandemic (H1N1) 2009 virus in New South Wales, Australia, we used results of a continuous population health survey. During July–September 2009, ILI was experienced by 23% of the population. Among these persons, 51% were unable to undertake normal duties for <3 days, 55% sought care at a general practice, and 5% went to a hospital. Factors independently associated with ILI were younger age, daily smoking, and obesity. Effectiveness of prepandemic seasonal vaccine was ≈20%. The high prevalence of risk factors associated with a substantially increased risk for ILI deserves greater recognition.

Terrorism in Australia : factors associated with perceived threat and incident-critical behaviours

BackgroundTo help improve incident preparedness this study assessed socio-demographic and socio-economic predictors of perceived risk of terrorism within Australia and willingness to comply with public safety directives during such incidents.MethodsThe terrorism perception question module was incorporated into the New South Wales Population Health Survey and was completed by a representative sample of 2,081 respondents in early 2007. Responses were weighted against the New South Wales population.ResultsMultivariate analyses indicated that those with no formal educational qualifications were significantly more likely (OR = 2.10, 95%CI:1.32–3.35, p < 0.001) to think that a terrorist attack is very or extremely likely to occur in Australia and also more likely (OR = 3.62, 95%CI:2.25–5.83, p < 0.001) to be very or extremely concerned that they or a family member would be directly affected, compared to those with a university-level qualification. Speaking a language other than English at home predicted high concern (very/extremely) that self or family would be directly affected (OR = 3.02, 95%CI:2.02–4.53, p < 0.001) and was the strongest predictor of having made associated changes in living (OR = 3.27, 95%CI:2.17–4.93, p < 0.001). Being female predicted willingness to evacuate from public facilities. Speaking a language other than English at home predicted low willingness to evacuate.ConclusionLow education level is a risk factor for high terrorism risk perception and concerns regarding potential impacts. The pattern of concern and response among those of migrant background may reflect secondary social impacts associated with heightened community threat, rather than the direct threat of terrorism itself. These findings highlight the need for terrorism risk communication and related strategies to address the specific concerns of these sub-groups as a critical underpinning of population-level preparedness.

Are messages about lifestyle walking being heard? : trends in walking for all purposes in New South Wales (NSW), Australia

OBJECTIVE To examine population trends in lifestyle walking in New South Wales (NSW), Australia between 1998 and 2006. METHODS Computer Assisted Telephone Interviewing surveys were conducted in 1998 and annually from 2002 to 2006. The weighted and standardized prevalence estimates of any walking (AW) for exercise, recreation or travel (i.e. > or =10 min/week) and of regular walking (RW) (i.e. > or =150 mins/week over > or =5 occasions) in population sub-groups were determined for each year. Adjusted annual change was calculated using multiple regression analyses. RESULTS The prevalence of AW was high in 1998 (80.0%, 95% CI: 79.4%-80.6%) and increased to 83.5% (95% CI: 82.7%-84.3%) in 2006. The prevalence of RW was stable between 1998 and 2003 ( approximately 29%), and gradually increased between 2004 (32.9%, 95% CI: 32.0%-33.8%) and 2006 (36.5%, 95% CI: 35.4%-37.6%). The yearly increases differed in magnitude but were significant for all population sub-groups including 75 years and older, the obese, people living in remote locations and those in the most disadvantaged socio-economic status quintile. Socio-economic differential in RW was no longer significant in 2006. CONCLUSION Over time, everyday walking has the potential to reduce health inequalities that is due to inactivity. Public health efforts to promote active living and address obesity, as well as a rise in gasoline prices, might have contributed to this trend.

Public health measures during an anticipated influenza pandemic: Factors influencing willingness to comply

This research assessed factors associated with willingness to comply with vaccination, isolation, and face mask wearing during an anticipated influenza pandemic. Data were collected from 2081 adults (16+) using a module of questions incorporated into the NSW Health Adult Population Health Survey. High levels of willingness to comply were reported with 73% either very or extremely willing to receive vaccination, 67% willing to isolate themselves, 58% willing to wear a face mask, and 48% willing to comply with all three behaviors. Further analysis indicated concern for self and family and higher levels of education were associated with high levels of willingness to comply. Younger people (16–24) were the least willing to comply; especially with wearing a face mask. Those with children reported higher levels of willingness to receive vaccination, and respondents who speak a language other than English at home were less willing to isolate themselves or comply with all behaviors. These findings provide a baseline measure of anticipated public compliance with key public health behaviors in the event of an influenza pandemic in the Australian population, and help to identify groups that may be more resistant to individual measures and may require additional attention in terms of risk communication strategies or health education.

Factors associated with population risk perceptions of continuing drought in Australia

OBJECTIVE To determine factors associated with risk perception of continuing drought in Australia. DESIGN AND SETTING Computer Assisted Telephone Interview survey. The sample was weighted to the New South Wales population. PARTICIPANTS A total of 2004 adults aged 16 years and over. RESULTS Overall 55.9% of the respondents thought drought was extremely or very likely to continue, 60.1% were extremely or very concerned that they or their family would be affected, and 86.3% reported that they had made some level of change to the way that they lived their lives because of the perceived risk of continuing drought. After controlling for confounding factors, the odds of perceived drought being extremely or very likely to continue, concern for self or family and making changes to behaviour because of the possibility of continuing drought were significantly higher in women than men by 43%, 59% and 86%, respectively. Compared with those who lived in highly accessible geographical areas, respondents who lived in remote or very remote geographical areas were 3.22 (adjusted odds ratios = 3.22; 95% CI, 1.69-6.14) times more likely to think that drought would continue and were 3.72 (adjusted odds ratios = 3.72; 95% CI, 1.10-12.56) times more likely to have changed the way they lived their lives because of the possibility of continuing drought. CONCLUSION Over half of the New South Wales population thought drought was very or extremely likely to continue. The baseline data collected in this survey will be useful for monitoring changes over time in the populations perceptions of continuing drought.
