A Longitudinal Analysis of Mid-Age Women's Use of Complementary and Alternative Medicine (CAM) in Australia, 1996–1998

ABSTRACT Complementary and Alternative Medicine (CAM) has become increasingly popular amongst healthcare consumers worldwide. As such, CAM is now an important public health issue with serious implications for healthcare organization and delivery. While previous studies have provided a profile of CAM users, there remains very limited analysis of CAM consumption over time. The purpose of this paper is to describe the changing use of CAM practitioners over time by 11,454 mid-age women in the Australian Longitudinal Study on Womens Health. Over the study period (1996–1998), 10% of women adopted the use of CAM and 9% relinquished CAM. The predominant factor found to be predictive of CAM adoption was changes in health status. Specifically, those women experiencing more illness over time are more likely to adopt CAM than those experiencing no change or better health. CAM relinquishment was associated with use of non-prescription medications, where women were more likely to relinquish CAM if they never used non-prescription medications or if they stopped taking non-prescription medications. This paper constitutes an exploratory investigation into CAM use over time. As such, there is need for further research to provide in-depth examination of the adoption and relinquishment of CAM use over a longer time period.

A longitudinal analysis of older Australian women's consultations with complementary and alternative medicine (CAM) practitioners, 1996–2005

OBJECTIVE to determine the factors associated with complementary and alternative medicine (CAM) use among older Australian women over time. METHODS a longitudinal analysis of postal questionnaires completed in 1996, 1999, 2002 and 2005 as part of the Australian Longitudinal Study on Womens Health. RESULTS the percentage of women who consulted a CAM practitioner in the years 1996, 1999, 2002 and 2005 were 14.6%, 12.1%, 10.9% and 9.9%, respectively. Use of CAM increased as the number of reported symptoms increased and physical health deteriorated, for non-urban residents compared to urban residents. CONCLUSION use of CAM amongst older women appears to be strongly influenced by poor physical health. There is also a suggestion that lack of access to conventional health care providers increases CAM use. There is also an overall decline in the use of CAM among older women as they age.

The characteristics of middle aged australian women who consult acupuncturists

Background Although an increase in the use of acupuncture in recent years has been identified, there are few studies that focus attention upon the characteristics of acupuncture users. This survey aimed at providing a first step towards addressing this significant research gap. Methods This study was conducted as part of the Australian Longitudinal Study on Womens Health, and examined the characteristics of acupuncture users among middle aged Australian women between 50 and 55 years old. Data were collected on demographic measures, health status and health service use. Results The paper reports on 11 202 middle aged women, surveyed in 2001. We estimate that 4.5% of middle aged women consult an acupuncturist. Women who consult an acupuncturist are less likely to be married or living in a de facto relationship, are more likely to have had a major personal illness in the previous year, to have suffered from a variety of symptoms or have significantly lower scores (ie poorer health) on all eight dimensions of the SF-36 health-related quality of life scale. Women who use acupuncture are also higher users of ‘conventional’ health services. Conclusion While the development of a research base and clinical applications for acupuncture are ongoing, health professionals should be aware that acupuncture is currently being used by large numbers of middle aged women. In addition, given the relatively higher prevalence of acupuncture use reported in our study, it is important that further research explores acupuncture use in more detail and the relationship between womens health issues and their use and experience of acupuncture.

Transforming the SF-36 to account for death in longitudinal studies with three-year follow-up

Background:Analyses of longitudinal health-related quality of life data often exclude participants who die, which limits the generalizability of the results. Methods to incorporate death as a valid score in the Medical Outcomes Study Short-Form (SF-36) have been suggested but need to be evaluated in other populations. Objectives:We sought to apply a method of transforming the SF-36 Physical Component Score (PCS) to include death. A transformation to estimate the probability of being “healthy” in 3 years, based on the current PCS value, will be developed and validated. Subjects:Women in the Australian Longitudinal Study on Womens Health (ALSWH), ages 70–75 years at Survey 1 in 1996 (n = 12,432), were followed-up at 3 yearly intervals for 6 years. Results:The transformation derived from the ALSWH data provides evidence that the methodology for transforming the PCS to account for deaths is sound. The 3-year equation provided good estimates of the probability of being healthy in 3 years and the method allowed deaths to be included in an analysis of changes in health over time. Conclusions:For longitudinal studies involving the SF-36 in which subjects have died, we support the recommendation that both the PCS and its transformed value which includes deaths should be analyzed to examine the influence of deaths on the study conclusions. Using study data to derive empirical parameters for the transformations may be appropriate for studies with follow-up intervals of other lengths.
