The Australian Longitudinal Study on Women's Health (ALSWH), also known as Women's Health Australia, is an ongoing population-based survey examining the health of over 50,000 Australian women. The study is funded by the Australian Government Department of Health and is a collaborative endeavour conducted by staff and investigators at The University of Newcastle and The University of Queensland. [1] The current directors are Professor Gita Mishra (The University of Queensland) and Professor Deborah Loxton (The University of Newcastle).
In 1996, women in three age groups (born 1973–78, 1946–51 and 1921–26) were randomly selected from the national Medicare database. These women were sent an invitation by mail to participate in the study. Over 40,000 women responded and agreed to participate. These women represented 2-3% of women in their age groups living in urban, rural and remote areas of Australia at that time. [2]
In 2012–13, an additional cohort of women aged 18–23 was recruited. Over 17,000 women were recruited using social media.[ citation needed ]
The primary method of data collection employed by ALSWH is self-completed surveys. ALSWH also includes a qualitative data set, where participants are asked to write anything they feel is important to their health and wellbeing in a free response space at the end of the survey. [3]

As well as completing the main surveys, participants are occasionally invited to participate in substudies that aim to examine selected issues in more depth. [4] A wide range of topics has been covered, including:[ citation needed ]
ALSWH has approval to anonymously link survey data with a number of national and state-based administrative datasets. Currently these approvals include the National Death Index, Medicare data, [5] state-based cancer registries, perinatal data collections and hospital admission datasets. The aim of linking to these datasets is to provide new insights into the health and health service use of Australian women, taking into account individual level differences in socioeconomic, behavioural, environmental and other risk factors. In the context of a changing health system, it is important to be able to monitor and evaluate the impact and outcomes of health service policy and practice.[ citation needed ]
The longitudinal study design ensures that the same women are followed over many years so researchers can observe changes in their health, clarify cause-and-effect relationships, and assess the effects of changes in policy and practice. ALSWH can provide information about the health of women across the lifespan. This information has assisted federal and state governments to plan for the future and to develop and evaluate health policy and practice relevant to Australian women. The study was used extensively in the 2010 National Women's Health Policy and the National Women's Health Strategy 2020–2030. [6]
ALSWH has collaborated with numerous investigators, universities and organisations around the world. The findings from ALSWH have been reported in over 100 reports to the government, [7] and been included in more than 1000 academic publications. [8]
Menstruation is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. The menstrual cycle is characterized by the rise and fall of hormones. Menstruation is triggered by falling progesterone levels and is a sign that pregnancy has not occurred.
Menopause, also known as the climacteric, is the time when menstrual periods permanently stop, marking the end of reproduction. It typically occurs between the ages of 45 and 55, although the exact timing can vary. Menopause is usually a natural change. It can occur earlier in those who smoke tobacco. Other causes include surgery that removes both ovaries or some types of chemotherapy. At the physiological level, menopause happens because of a decrease in the ovaries' production of the hormones estrogen and progesterone. While typically not needed, a diagnosis of menopause can be confirmed by measuring hormone levels in the blood or urine. Menopause is the opposite of menarche, the time when a girl's periods start.
Postpartum depression (PPD), also called postnatal depression, is a mood disorder experienced after childbirth, which can affect women. Symptoms may include extreme sadness, low energy, anxiety, crying episodes, irritability, and changes in sleeping or eating patterns. PPD can also negatively affect the newborn child.
Teenage pregnancy, also known as adolescent pregnancy, is pregnancy in a female adolescent under the age of 20.
Women's health differs from that of men's health in many unique ways. Women's health is an example of population health, where health is defined by the World Health Organization (WHO) as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". Often treated as simply women's reproductive health, many groups argue for a broader definition pertaining to the overall health of women, better expressed as "The health of women". These differences are further exacerbated in developing countries where women, whose health includes both their risks and experiences, are further disadvantaged.
The National Center for Health Statistics (NCHS) is a U.S. government agency that provides statistical information to guide actions and policies to improve the public health of the American people. It is a unit of the Centers for Disease Control and Prevention (CDC) and a principal agency of the U.S. Federal Statistical System. It is headquartered at University Town Center in Hyattsville, Maryland, just outside Washington, D.C.
The Women's Health Initiative (WHI) was a series of clinical studies initiated by the U.S. National Institutes of Health (NIH) in 1991, to address major health issues causing morbidity and mortality in postmenopausal women. It consisted of three clinical trials (CT) and an observational study (OS). In particular, randomized controlled trials were designed and funded that addressed cardiovascular disease, cancer, and osteoporosis.
Bioidentical hormone replacement therapy (BHRT), also known as bioidentical hormone therapy (BHT) or natural hormone therapy, is the use of hormones that are identical on a molecular level with endogenous hormones in hormone replacement therapy. It may also be combined with blood and saliva testing of hormone levels, and the use of pharmacy compounding to obtain hormones in an effort to reach a targeted level of hormones in the body. A number of claims by some proponents of BHT have not been confirmed through scientific testing. Specific hormones used in BHT include estrone, estradiol, progesterone, testosterone, dehydroepiandrosterone (DHEA), and estriol.
A longitudinal study is a research design that involves repeated observations of the same variables over long periods of time. It is often a type of observational study, although it can also be structured as longitudinal randomized experiment.
Gender is correlated with the prevalence of certain mental disorders, including depression, anxiety and somatic complaints. For example, women are more likely to be diagnosed with major depression, while men are more likely to be diagnosed with substance abuse and antisocial personality disorder. There are no marked gender differences in the diagnosis rates of disorders like schizophrenia and bipolar disorder. Men are at risk to suffer from post-traumatic stress disorder (PTSD) due to past violent experiences such as accidents, wars and witnessing death, and women are diagnosed with PTSD at higher rates due to experiences with sexual assault, rape and child sexual abuse. Nonbinary or genderqueer identification describes people who do not identify as either male or female. People who identify as nonbinary or gender queer show increased risk for depression, anxiety and post-traumatic stress disorder. People who identify as transgender demonstrate increased risk for depression, anxiety, and post-traumatic stress disorder.
NORC at the University of Chicago, previously the National Opinion Research Center, is an independent social research organization in the United States. Established in 1941, its corporate headquarters is located in downtown Chicago, with offices in several other locations throughout the United States. Organized as an independent corporation, more than half its board comes from faculty and administration of the University of Chicago. It also jointly staffs some of the university's academic research centers.
In fields such as epidemiology, social sciences, psychology and statistics, an observational study draws inferences from a sample to a population where the independent variable is not under the control of the researcher because of ethical concerns or logistical constraints. One common observational study is about the possible effect of a treatment on subjects, where the assignment of subjects into a treated group versus a control group is outside the control of the investigator. This is in contrast with experiments, such as randomized controlled trials, where each subject is randomly assigned to a treated group or a control group. Observational studies, for lacking an assignment mechanism, naturally present difficulties for inferential analysis.
Health services research (HSR) became a burgeoning field in North America in the 1960s, when scientific information and policy deliberation began to coalesce. Sometimes also referred to as health systems research or health policy and systems research (HPSR), HSR is a multidisciplinary scientific field that examines how people get access to health care practitioners and health care services, how much care costs, and what happens to patients as a result of this care. HSR utilizes all qualitative and quantitative methods across the board to ask questions of the healthcare system. It focuses on performance, quality, effectiveness and efficiency of health care services as they relate to health problems of individuals and populations, as well as health care systems and addresses wide-ranging topics of structure, processes, and organization of health care services; their use and people's access to services; efficiency and effectiveness of health care services; the quality of healthcare services and its relationship to health status, and; the uses of medical knowledge.
Hormone replacement therapy (HRT), also known as menopausal hormone therapy or postmenopausal hormone therapy, is a form of hormone therapy used to treat symptoms associated with female menopause. Effects of menopause can include symptoms such as hot flashes, accelerated skin aging, vaginal dryness, decreased muscle mass, and complications such as osteoporosis, sexual dysfunction, and vaginal atrophy. They are mostly caused by low levels of female sex hormones that occur during menopause.
Gender-biased diagnosing is the idea that medical and psychological diagnosis are influenced by the patient's gender. Several studies have found evidence of differential diagnosis for patients with similar ailments but of different sexes. Female patients face discrimination through the denial of treatment or miss-classification of diagnosis as a result of not being taken seriously due to stereotypes and gender bias. According to traditional medical studies, most of these medical studies were done on men thus overlooking many issues that were related to women's health. This topic alone sparked controversy and questions about the medical standard of our time. Popular media has illuminated the issue of gender bias in recent years. Research that was done on diseases that affected women more were less funded than those diseases that affected men and women equally.
A women's health nurse practitioner (WHNP) is a nurse practitioner that specializes in continuing and comprehensive healthcare for women across the lifespan with emphasis on conditions unique to women from menarche through the remainder of their life cycle.
Women's reproductive health in Russia refers to the set of physical, mental, and social health issues and services available to women in Russia. It includes the rights, laws, and problems experienced by women and their families regarding proper reproductive health. Women account for over half of the Russian population and are considered a vulnerable population due to political and social problems from inequalities in gender, age, socioeconomic status, and geographical location that affect access to comprehensive health care. As Russia struggles with a decreasing birthrate and increase in STIs, HIV, and poor reproductive health care, the need for government financed services and international programs is essential to successfully reach this vulnerable population. Currently, women in Russia access care through government funded free services, private insurance, and NGO programs.
Women's reproductive health in the United States refers to the set of physical, mental, and social issues related to the health of women in the United States. It includes the rights of women in the United States to adequate sexual health, available contraception methods, and treatment for sexually transmitted diseases. The prevalence of women's health issues in American culture is inspired by second-wave feminism in the United States. As a result of this movement, women of the United States began to question the largely male-dominated health care system and demanded a right to information on issues regarding their physiology and anatomy. The U.S. government has made significant strides to propose solutions, like creating the Women's Health Initiative through the Office of Research on Women's Health in 1991. However, many issues still exist related to the accessibility of reproductive healthcare as well as the stigma and controversy attached to sexual health, contraception, and sexually transmitted diseases.
Cardiovascular disease in women is an integral area of research in the ongoing studies of women's health. Cardiovascular disease (CVD) is an umbrella term for a wide range of diseases affecting the heart and blood vessels, including but not limited to, coronary artery disease, stroke, cardiomyopathy, myocardial infarctions, and aortic aneurysms.
The Women's Healthy Ageing Project (WHAP) is the longest ongoing medical research project examining the health of Australian women. Its landmark studies concern women's heart and brain health, a long-neglected area of specialised research.
