Article
Full-text available
Background National mortality statistics are only based on the underlying cause of death, which may considerably underestimate the effects of some chronic conditions. Methods The sensitivity, specificity, and positive and negative predictive values for diabetes (a common precursor to multimorbidity), dementia (a potential accelerant of death) and...
Article
Background Women with lower body mass index (BMI) have a higher risk of surgically confirmed endometriosis but this finding runs counterintuitive to the oestrogen-dependent theory for the disease. Increasingly, endometriosis is diagnosed via non-surgical methods. We examined BMI at age 18–23 years, and changes in BMI, and the risk of endometriosis...
Article
Full-text available
Background Previous studies of lifestyle characteristics and risk of miscarriage have mostly been retrospective and failed to account for induced abortions. We examine whether pre-pregnancy body-mass index, alcohol intake and smoking influence the risk of miscarriage after accounting for induced abortions. Methods We conducted a prospective cohort...
Article
Study question: Do the outcomes and use of ART differ between women with and without endometriosis? Summary answer: ART use and outcome do not appear to differ for women with and without endometriosis, as long as endometriosis is diagnosed prior to commencing ART. What is known already: Approximately 40% of women with endometriosis have infert...
Article
Purpose Endometriosis is a chronic inflammatory disease affecting the reproductive, gastrointestinal and urinary systems. We examined changes in labour force participation among women with endometriosis following diagnosis. Methods We analysed data from 4494 women born in 1973-78 from the Australian Longitudinal Study on Women's Health. We used mu...

Objectives and Approach Our goal was to use data linkage to obtain clinically validated data on the incidence of a range of common chronic conditions developed by participants in the Australian Longitud...
Article
Objectives To assess the impact of dementia on the use of health and community services in the last 2 years of life by women who also had other major chronic conditions. Design Matched groups of women with a chronic condition who did or did not also have dementia, and who died or did not die for at least another 2 years. Setting and Participants...
Article
Full-text available
Background: Use of generalized linear models with continuous, non-linear functions for age, period and cohort makes it possible to estimate these effects so they are interpretable, reliable and easily displayed graphically. To demonstrate the methods we use data on the prevalence of obesity among Australian women from two independent data sources...
Article
Background Depressive symptoms fluctuate over time, and are most common amongst women in early adulthood. Understanding predictors of changes in depressive symptoms among young women may inform health promotion and early intervention. Methods Data were collected at three-yearly intervals from 2000 (Survey 2) to 2012 (Survey 6) from the Australian...

Article
In 1996 the Australian Longitudinal Study on Women's Health recruited a nationally representative sample of more than 40 000 women in three age cohorts, born in 1973-78, 1946-51 and 1921-26. At least six waves of 3-yearly surveys have been completed. Although the focus remains on factors affecting the health and well-being of women and their access...
Technical Report
Full-text available
51% of women in the 1946-51 cohort have arthritis at age 62-67. This prevalence is already higher than the prevalence of arthritis among women in the 1921-26 cohort when they were aged 73-75.  MBS and PBS costs are $1000 higher for women with arthritis in the 1946-51 cohort compared to women with no arthritis. Costs are $500 higher among women in...
Article
Although social support is a significant contributor to health and well-being, little is known about patterns of perceived social support over time in young adulthood. It is also unclear which personal characteristics are associated with different patterns, and whether there is an association between social support and mental health over time. We e...
Article
Full-text available
Background: Faced with the challenge of recruiting young adults for health studies, researchers have increasingly turned to the Internet and social networking sites, such as Facebook, as part of their recruitment strategy. As yet, few large-scale studies are available that report on the characteristics and representativeness of the sample obtained...
Article
Purpose: The influence of social support on health and quality of life has been well documented. There is less evidence on whether health status affects social support, and little is known about longitudinal relationships between social support and health in early adulthood. This study investigates these associations using both concurrent and time...
Article
Purpose: This study aimed to validate a 6-item 1-factor global measure of social support developed from the Medical Outcomes Study Social Support Survey (MOS-SSS) for use in large epidemiological studies. Methods: Data were obtained from two large population-based samples of participants in the Australian Longitudinal Study on Women's Health. Th...

Descriptive design with a prospective cohort. Little is known about the long-term relationship between the duration of treatment using dynamic orthoses (splints), and contracture resolution in the stiff proximal interphalangeal (PIP) joint. To examine the long-term relationship between weeks of treatment using dynamic orthoses and contracture resol...
Article
Full-text available
Generalisability of longitudinal studies is threatened by issues such as choice of sampling frame, representativeness of the initial sample, and attrition. To determine representativeness, cohorts are often compared with the population of interest at baseline on demographic and health characteristics. This study illustrates the use of relative surv...
Article
Full-text available
Interpretation of changes in health and health care utilization patterns across the life span depends on an understanding of the effects of age, period, and cohort. The purpose of this article is to illustrate differences among three generations of women in demographic factors, health risk factors, and health status indicators from 1996 to 2008. Th...
Article
Women often blame weight gain in early adulthood on having a baby. The aim was to estimate the weight gain attributable to having a baby, after disentangling the effects of other factors that influence weight change at this life stage. A longitudinal study of a randomly selected cohort of 6458 Australian women, aged 18-23 years in 1996, was conduct...
Article
This study explores risk factors for height loss and consequences in terms of health and wellbeing, in older women. Osteoporosis, low body-mass index, being born in Europe and using medications for both sleep and anxiety were risk factors for height loss. Height loss was associated with digestive problems; excessive height loss was also associated...
Article
Objective: To investigate whether overweight women are more likely to have a hysterectomy and whether hysterectomy leads to increased weight gain. Methods: Survey data of middle-aged women participating in the Australian Longitudinal Study on Women's health in 1996 (ages 45-50 y; n = 13,125), 1998 (n = 10,612), 2001 (n = 10,293), and 2004 (n = 9309...
