Objectives:
The objectives of this study were to identify the prevalence of the use of vitamin/mineral supplements or natural/herbal remedies, concurrent use of pharmaceutical medication, and to profile those most likely to use these complementary and alternative medicines (CAM) in the treatment of five chronic conditions identified as national health priorities (asthma, diabetes, arthritis, osteoporosis, heart or circulatory condition) within the Australian adult population.
Methods:
Analysis of the Australian National Health Survey database, 2004–05.
Results:
Approximately 24% (1.3 million) of Australian adults with a chronic condition regularly applied CAM to treatment. CAM was most often used exclusively or in combination with pharmaceutical medicine in the treatment of arthritis and osteoporosis. Fewer than 10% of adults with asthma, diabetes or a heart or circulatory condition used CAM, most preferring pharmaceutical medicine. Regular CAM users were more likely to be aged ≥60, female, have a secondary school education and live in households with lower incomes than non‐users. Non‐users were more likely to be 30–59 years old and tertiary educated.
Conclusion and implications:
Arthritis, osteoporosis and, to a lesser extent, heart or circulatory conditions are illnesses for which doctors should advise, and patients need to be most aware about the full effects of CAM and possible interactive effects with prescribed medicine. They are also conditions for which research into the interactive effects of CAM and pharmaceutical medication would seem of most immediate benefit.
RESEARCH DESIGN AND METHODS -Insulin-treated diabetic subjects (n = 1,008) on the Canterbury Diabetes Registry were tracked over 9 years, and their vital status was determined. Death rates were standardized using direct and indirect methods. Cox proportional hazard regression was used to model the effects of demographic and clinical covariates on survival time.RESULTS -At study entry, age ranged from 2.9 to 92.7 years, with mean 48.7 ± 20.4 years; age at diagnosis was 0.2-88.9 years, mean 34.5 ± 20.0 years; and duration of diabetes was 0.1-58.5 years, mean 14.0 ± 10.6 years. There were 303 deaths in 7,372 person-years of follow-up with a standardized mortality ratio (SMR) of 2.6 (95% CI 2.4-3.0). Relative mortality was greatest for those aged 30-39 years .2]). The death rate for the diabetic cohort standardized against the Segi world standard population was 16.2 per 1,000. Attained age, sex, and clinical subtype were significant predictors of mortality. The SMR for subjects with type 1 diabetes and age at onset Ͻ30 years was 3.7 (CI 2.7-5.0), 2.2 (1.8-2.6) for those with onset Ն30 years, and 3.1 (2.5-3.7) for subjects suspected of having latent autoimmune diabetes in adulthood or insulin-treated type 2 diabetes. Life expectancy was reduced for both sexes at all ages.CONCLUSIONS -Mortality rates for insulin-treated diabetic individuals remain high, resulting in shortened life spans relative to the general population. Marked differences in mortality exist between clinical groups of subjects. Further research is needed to improve diabetes classification and to clarify differences in health outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
