Data-driven lifestyle patterns and risk of dementia in older Australian women.

INTRODUCTION: Many lifestyle factors have been associated with dementia, but there is limited evidence of how these group together. The aim of this study was to examine the clustering of lifestyle behaviors and associations with dementia. METHODS: This population-based study included 9947 older Australian women. Latent class analysis was employed to identify distinct lifestyle classes, and Cox proportional hazard regression compared these with incident dementia over 17 years. RESULTS: Three classes were identified: (1) "highly social and non-smokers" (54.9%), (2) "highly social, smokers, and drinkers" (25.1%), and (3) "inactive and low socializers" (20.0%). Women in Class 3 exhibited a higher risk of dementia compared to both Class 1 (hazard ratio [HR] = 1.19, 95% confidence interval [CI]: 1.08 to 1.30) and Class 2 (HR = 1.12, 95% CI: 1.00 to 1.25). DISCUSSION: A lifestyle pattern characterized by physical inactivity and low social engagement may be particularly detrimental for dementia risk in older women and should be prioritized in preventive strategies. HIGHLIGHTS: Latent class analysis was employed to identify distinct lifestyle clusters. Three lifestyle-related clusters were differentially associated with dementia risk. Inactive and low socializers exhibited the greatest risk of dementia. Targeting physical inactivity and low social engagement in prevention is vital.

Understanding the relationship between eye disease and driving in very old Australian women: a longitudinal thematic evaluation.

BACKGROUND: Over recent decades an increasing number of adults will retain their driver's licenses well into their later years. The aim of this study was to understand and explore the experience of driving and driving cessation in very old Australian women with self-reported eye disease. METHODS: An interpretative qualitative study. Participants were from the Australian Longitudinal Study on Women's Health (cohort born in 1921-26), a sample broadly representative of similarly aged Australian women. Responses to open-ended questions were analysed using an inductive thematic approach, employing a process of constant comparison. RESULTS: Qualitative data were from 216 older women with eye disease who made 2199 comments about driving, aged between 70 and 90 years depending on the timing of their comments. Themes included: (1) Access to treatment for eye disease promotes driving independence and quality of life; (2) Driving with restrictions for eye disease enables community engagement and (3) Driving cessation due to poor vision leads to significant lifestyle changes. CONCLUSIONS: Key findings highlighted driving cessation, or reduction, is often attributed to deterioration in vision. The consequence is dependence on others for transport, typically children and friends. Access to successful treatment for eye disease allowed older women to continue driving. We posit that occupational therapists can play an essential role in promote driving confidence and ability as women age. TRIAL REGISTRATION: Not applicable.

Common combinations of medications used among oldest-old women: a population-based study over 15 years.

BACKGROUND: Older people use many medications, but combinations of medications used among the oldest old (≥ 80 years) are not commonly reported. AIMS: This study aimed to determine common combinations of medications used among women aged 77-96 years and to describe characteristics associated with these combinations. METHODS: A cohort study of older women enroled in the Australian Longitudinal Study on Women's Health over a 15-year period was used to determine combinations of medications using latent class analysis. Multinomial logistic regression was used to determine characteristics associated with these combinations. RESULTS: The highest medication users during the study were for the cardiovascular (2003: 80.28%; 2017: 85.63%) and nervous (2003: 66.03%; 2017: 75.41%) systems. A 3-class latent model described medication use combinations: class 1: 'Cardiovascular & neurology anatomical group' (27.25%) included participants using medications of the cardiovascular and nervous systems in their later years; class 2: 'Multiple anatomical group' (16.49%) and class 3: 'Antiinfectives & multiple anatomical group' (56.27%). When compared to the reference class (class 1), the risk of participants being in class 3 was slightly higher than being in class 2 if they had > 4 general practitioner visits (RRR 2.37; 95% CI 2.08, 2.71), Department of Veterans Affairs' coverage (RRR 1.59; 95% CI 1.36, 1.86), ≥ 4 chronic diseases (RRR 3.16; 95% CI 2.56, 3.90) and were frail (RRR 1.47; 95% CI 1.27, 1.69). CONCLUSION: Identification of combinations of medication use may provide opportunities to develop multimorbidity guidelines and target medication reviews, and may help reduce medication load for older individuals.

Do health assessments affect time to permanent residential aged care admission for older women with and without dementia?

AIM: To investigate the effect of health assessments on permanent residential aged care admission for older Australian women with and without dementia. METHODS: A total of 1427 older Australian women who had a health assessment between March 2002 and December 2013 were matched with 1427 women who did not have a health assessment in the same period. Linked administrative datasets were used to identify health assessment use, admission to permanent residential aged care, and dementia status. Outcome was time to residential aged care admission from the matched date of health assessment. RESULTS: Women who had health assessments were less likely to be admitted to residential aged care in the short term (100 days), irrespective of dementia status (subdistribution hazard ratio [SDHR] = 0.35, 95% CI = [0.21, 0.59] for women with dementia; SDHR = 0.39, 95% CI = [0.25, 0.61] for women without dementia). However, there were no significant differences at 500- and 1000-days follow-up. At 2000-days follow-up, women who had a health assessment were more likely to be admitted to residential aged care, regardless of dementia status (SDHR = 1.41, 95% CI = [1.12, 1.79] for women with dementia; SDHR = 1.55, 95% CI = [1.32, 1.82] for women without dementia). CONCLUSIONS: Benefits from health assessments may depend on the recency of the assessment, with women less likely to be admitted to residential aged care in the short term after a health assessment. Our results add to a growing body of literature suggesting that health assessments may provide benefits to older people, including those with dementia. Geriatr Gerontol Int 2023; 23: 595-602.

Patterns of Labour Interventions and Associated Maternal Biopsychosocial Factors in Australia: a Path Analysis.

In Australia, nearly half of births involve labour interventions. Prior research in this area has relied on cross-sectional and administrative health data and has not considered biopsychosocial factors. The current study examined direct and indirect associations between biopsychosocial factors and labour interventions using 19 years of population-based prospective data. The study included singleton babies among primiparous women of the 1973-1978 cohort of the Australian Longitudinal Study on Women's Health. Data from 5459 women who started labour were analysed using path analysis. 42.2% of babies were born without intervention (episiotomy, instrumental, or caesarean delivery): Thirty-seven percent reported vaginal birth with episiotomy and instrumental birth interventions, 18% reported an unplanned caesarean section without episiotomy and/or instrumental interventions, and 3% reported unplanned caesarean section after episiotomy and/or instrumental interventions. Vaginal births with episiotomy and/or instrumental interventions were more likely among women with chronic hypertension (RRR(95%-CI):1.50(1.12-2.01)), a perceived length of labour of more than 36 h (RRR(95%-CI):1.86(1.45-2.39)), private health insurance (RRR(95%-CI):1.61(1.41-1.85)) and induced labour (RRR(95%-CI):1.69(1.46-1.94)). Risk factors of unplanned caesarean section without episiotomy and/or instrumental birth intervention included being overweight (RRR(95%-CI):1.30(1.07-1.58)) or obese prepregnancy (RRR(95%-CI):1.63(1.28-2.08)), aged ≥ 35 years (RRR(95%-CI):1.87(1.46-2.41)), having short stature (< 154 cm) (RRR(95%-CI):1.68(1.16-2.42)), a perceived length of labour of more than 36 h (RRR(95%-CI):3.26(2.50-4.24)), private health insurance (RRR(95%-CI):1.38(1.17-1.64)), and induced labour (RRR(95%-CI):2.56(2.16-3.05)). Prevention and management of hypertension, diabetes, and obesity during preconception and/or antenatal care are keys for reducing labour interventions and strengthening the evidence-base around delivery of best practice obstetric care.

The experience of delayed health care access during the COVID 19 pandemic in Australian women: A mixed methods exploration.

Delayed health care access is a potential collateral effect of pandemic conditions, health rationing strategies and social distancing responses. We investigated experiences of delayed health care access in Australian women during COVID-19. A mixed methods study used quantitative and free-text data from the Australian Longitudinal Study on Women's Health COVID-19 survey 4 (health care access or delay). Logistic regression models were used to estimate factors associated with delaying access to general practitioners (GPs), specialists and allied health services. Free-text comments were analysed thematically, employing a process of constant comparison. COVID-19 survey 4 was completed by 8,200 women and 2,727 provided free-text comments. Of the women who needed the health service, 25% (1,268/5,071) delayed seeing their GP, 23.6% (570/1,695) delayed seeing a specialist and 45% (791/1,757) delayed use of an allied health service. Younger age was most significantly associated with delaying attendance. Women born 1989-95 were significantly more likely to delay compared to women born 1946-51 (OR (95% CI): GP = 0.28 (0.22, 0.35)); Specialist = 0.65 (0.45, 0.92; Allied Health = 0.59 (0.42, 0.82)). Women born 1973-78 were also likely to delay GP visits (0.69, (0.58, 0.83)). Four qualitative themes emerged including: (1) Challenges negotiating care during a pandemic; (2) Ongoing uncertainty towards accessing health care when a specialist delays an appointment; (3) Accessing health care (or not) using Telehealth and (4) Managing complex care needs. COVID-19 has had a significant effect on access to health care. Women delayed seeking help for cancer screening, mental health, and other health conditions involving chronic and complex needs for health and social care. While there is a need to rationalise and optimise health access during a pandemic, our outcomes suggest a need for public health campaigns that clarify how to access care, engage with telehealth and respond to missed appointments.

Use of medical services by older Australian women with dementia: a longitudinal cohort study.

OBJECTIVE: To assess the use of Medicare-subsidised health services by women with and without dementia. METHODS: Data from women of the 1921-26 birth cohort of the Australian Longitudinal Study on Women's Health were linked to various administrative datasets to ascertain dementia diagnosis. The use of subsidised general practitioner (GP) services (75+ health assessments [HAs], chronic disease management meetings [CDMs], multidisciplinary case conferences [MCCs]) and specialist and allied health services between 2000 and 2013 for these women was analysed using longitudinal GEE models. RESULTS: A total of 9,683 women were included with 1,444 (15%) women identified as having dementia. Compared to women with no dementia indication, women with dementia had more yearly non-emergency GP attendances (short [<30 minutes] IRR=1.11 [1.07, 1.13]; long [>30 minutes] IRR=1.11 [1.04, 1.19]) and fewer specialist attendances (IRR=0.91 [0.85, 0.97]) and were more likely to have an emergency GP attendance (OR=2.29 [2.05, 2.57]). There were no significant differences in the odds of having either a HA or CDM or using allied health services for women with and without dementia indicators. CONCLUSIONS: The overall use of services designed to improve the prevention and coordination of the care of older people with chronic conditions was low. Women with dementia were no more likely to access these services. Implications for public health: There is underuse of some primary and allied healthcare services designed for people with complex chronic conditions. These could be better used by women with dementia to improve the management of complex comorbidities (e.g. CDMs), to prevent the onset of disability (e.g. physiotherapy), and enhance needs assessment and service access (e.g. HAs).

The impact of adverse childhood experiences on the health and health behaviors of young Australian women.

BACKGROUND: Adverse childhood experiences have been linked to poor health and adverse health behavior in adulthood. OBJECTIVE: This study aimed to estimate the prevalence of adverse childhood experiences among young Australian women (aged 20-25) and examine associations between adverse childhood experiences and adult health behaviors and physical and mental health. PARTICIPANTS AND SETTINGS: Data were from the 1989-95 cohort of the Australian Longitudinal Study on Women's Health, who completed the Adverse Childhood Experiences Scale at Survey 3 in 2015 (N = 8609). METHODS: Outcomes included: self-rated health, sexual health, psychological distress, depression, anxiety, suicide ideation, self-harm, substance abuse (drinking, smoking, illicit drugs), severe obesity, and exercise. Prevalence of childhood adversities were presented, with the association between childhood adversity and outcomes evaluated using log-binomial multivariable regressions (99% CI). RESULTS: While 59% of women reported experiencing at least one childhood adversity, 10% of participants reported adverse childhood experiences across four or more categories, indicating a significant burden of risk for young Australian women. Women reporting four or more categories had higher rates of poor physical health (adjPR = 1.79, 99% CI = 1.51-2.12), sexually transmitted infections (adjPR = 1.36, 99% CI = 1.11-1.67), and poor mental health (adjPR = 2.78, 99% CI = 2.34-3.32), and increased rates of severe obesity (adjPR = 2.14, 99% CI = 1.61-2.86) and smoking (adjPR = 2.23, 99% CI = 1.89-2.64). CONCLUSION: Using nationally representative data, this study shows adverse childhood experiences directly impact physical and mental health, and health behaviors in adulthood among young Australian women. The management of health and wellbeing in adulthood should look beyond the contemporaneous factors, incorporating a focus on how childhood adversity may negatively influence health behavior, health and wellbeing in later life.

Alcohol-related risk from pre-loading and heavy episodic drinking (HED) among a cohort of young Australian women: a cross-sectional analysis.

OBJECTIVE: To cross-sectionally examine heavy episodic drinking (HED) and pre-loading with alcohol among young Australian women in relation to the alcohol-induced adverse outcomes of memory loss, vomiting and injury. METHODS: A total of 7,800 participants, aged 20-25 years, from the 1989-95 cohort of the Australian Longitudinal Study on Women's Health answered all questions on alcohol use, reported drinking alcohol in the previous year and were not pregnant at the third survey in 2015. Log-binomial models were used to estimate prevalence ratios for adverse outcomes associated with increased frequency of HED and pre-loading. RESULTS: The majority of participants reported HED (83.4%) and/or pre-loading (65.6%), which had a moderate correlation (r=0.646). Just over half (55.2%) of participants experienced at least one adverse event, with vomiting being most common. As the frequency of HED or pre-loading increased, so did the risk of an adverse outcome. CONCLUSIONS: Both HED and pre-loading pose a risk to young Australian women, and that risk rises with increased frequency. Implications for public health: Although HED has been a target of public health policy and interventions, pre-loading has received limited attention. In addition to addressing HED, there is a need to consider the risk posed by pre-loading, a related, yet unique risky drinking behaviour.
