Adherence to 24-h movement behaviour guidelines in families with multiple children.

Background: In 2019, the World Health Organization (WHO) launched the first global movement guidelines for children that combined sleep, physical activity and screen time. Our previous research showed that adherence to age-specific guidelines for screen time was challenging for families with children in different age groups. We aimed to determine whether families with children in different age-based movement guideline categories have poorer adherence to the broader 24-h movement guidelines than those with all children in the same age category.

Fertility treatment pathways and births for women with and without polycystic ovary syndrome-a retrospective population linked data study.

Objective: To study the fertility treatment pathways used by women with and without polycystic ovary syndrome (PCOS) and which pathways were more likely to result in a birth.

Design: This retrospective national community-based cohort study used longitudinal self-report survey data (collected 1996-2022; aged 18-49 years) from women born in 1973-1978 who are participants in the Australian Longitudinal Study on Women's Health. The study also used linked administrative data on fertility treatments (1996-2021).

Does Timing Matter? Associations Between Intimate Partner Violence Across the Early Life Course and Internalizing and Externalizing Behavior in Children.

The association between exposure to intimate partner violence (IPV) and child behavior problems is well established. However, questions remain about whether the timing during the child's early life course matters. We used a structured life course approach to investigate associations between the timing of IPV and children's internalizing and externalizing behaviors.

What happens after menopause? (WHAM): A prospective controlled study of symptom profiles up to 12 months after pre-menopausal risk-reducing salpingo-oophorectomy.

Objective: Understanding how symptoms cluster after premenopausal risk-reducing salpingo-oophorectomy (RRSO) can inform patient expectations but information is lacking. We aimed to identify symptom profiles after RRSO, changes over time, and the effect of hormone therapy (HT).

Method: Participants were premenopausal women from a longitudinal controlled study (What Happens After Menopause? (WHAM)).

History of pre-pregnancy maternal symptoms of binge eating and childhood behavioral problems in girls and boys.

Objective: To explore whether children of mothers with pre-pregnancy binge eating (BE) symptoms have more behavioral difficulties compared with those without and whether associations are moderated by ED symptoms and other maternal health and social factors measured during childhood.

Method: Pre-pregnancy BE symptoms were collected by the Australian Longitudinal Study on Women's Health at Survey 1 (in 1996) and/or at Survey 2 (in 2000) using questions mapped to DSM BE criterion 1. In 2016/7, 2180 women from the 1973-78 cohort provided data on externalizing and internalizing behavior, measured by Strengths and Difficulties Questionnaire, on 4054 of their children (2-12 years) in the Mothers and their Children's Health study.

Association between residential greenspace and health-related quality of life in children aged 0-12 years.

Introduction: Greenspaces generate several perceived health benefits, including an overall improvement in the quality of life. However, little is known about the effects of greenspaces through pregnancy and early childhood in promoting health-related quality of life (HRQoL) among children.

Method: Participants were from the Mothers and their Children's Health Study (MatCH), a 2016/17 sub-study of a national prospective study since 1996 known as the Australian Longitudinal Study on Women's Health (ALSWH).

Residential greenspace and early childhood development and academic performance: A longitudinal analysis of Australian children aged 4-12 years.

Introduction: Exposure to greenspaces has beneficial effects on children's mental health and development. This study explores the association between residential exposure to greenspace and early childhood development and academic outcomes.

Methods: Children were from Mothers and their Children's Health (MatCH) study, a sub-study of the Australian Longitudinal Study on Women's Health.

Adherence to Screen Time Guidelines Among Families in Australia With Children of Different Ages.

This cross-sectional study examines whether children of different ages in families in Australia follow age-based screen time guidelines.

Maternal and Childhood Ambient Air Pollution Exposure and Mental Health Symptoms and Psychomotor Development in Children: An Australian Population-Based Longitudinal Study.

Background: Accumulating evidence indicates early life exposure to air pollution, a suspected neurotoxicant, is negatively associated with children's neurodevelopment.

Objectives: To explore the role of multiple exposure periods to ambient particulate matter with diameter <2.5 μm (PM) and nitrogen dioxide (NO) on emotion and behaviour, and early development in children <13 years.

Screen time and child behaviour and health-related quality of life: Effect of family context.

This study investigated family contextual effects on the association between screen time, behaviour and health-related quality of life (HRQOL) in child siblings. Data were from 1772 participants in the Australian Longitudinal Study of Women's Health 1973-78 cohort and their three youngest children (N = 4010 siblings) aged two to 12, collected in Mothers and their Children's Health cross-sectional sub-study (2016/17). The exposure was average daily recreational screen time (televisions, computers, tablets, mobile phones, electronic games).

What happens after menopause? (WHAM): A prospective controlled study of vasomotor symptoms and menopause-related quality of life 12 months after premenopausal risk-reducing salpingo-oophorectomy.

Objective: To measure menopausal symptoms and quality of life up to 12 months after risk-reducing salpingo-oophorectomy (RRSO) and to measure the effects of hormone therapy.

Methods: Prospective observational study of 95 premenopausal women planning RRSO and a comparison group of 99 who retained their ovaries. Vasomotor symptoms and menopausal-related quality of life (QoL) were measured by the Menopause-Specific QoL Intervention scale at baseline, 3, 6 and 12 months.

What happens after menopause? (WHAM): A prospective controlled study of sleep quality up to 12 months after premenopausal risk-reducing salpingo-oophorectomy.

Objective: Sleep difficulties impair function and increase the risk of depression at menopause and premenopausal oophorectomy may further worsen sleep. However, prospective data are limited, and it remains uncertain whether Hormone Therapy (HT) improves sleep. This prospective observational study measured sleep quality before and up to 12 months after risk-reducing salpingo-oophorectomy (RRSO) compared to a similar age comparison group who retained their ovaries.

What Happens After Menopause? (WHAM): A prospective controlled study of cardiovascular and metabolic risk 12 months after premenopausal risk-reducing bilateral salpingo-oophorectomy.

Objective: To prospectively measure cardiometabolic risk 12 months after premenopausal risk-reducing bilateral salpingo-oophorectomy (RRBSO) compared to a similar age comparison group, and the effects of Hormone Therapy (HT) on cardiometabolic risk.

Methods: Prospective observational study of 95 premenopausal women planning RRBSO and 99 comparisons who retained their ovaries. At baseline and 12 months, blood pressure (BP), Body Mass Index (BMI), waist and hip circumference, fasting total, HDL and LDL cholesterol, triglycerides, high-sensitivity C-reactive protein, glucose and insulin were measured and HOMA-IR was calculated.

What happens after menopause? (WHAM): A prospective controlled study of depression and anxiety up to 12 months after premenopausal risk-reducing bilateral salpingo-oophorectomy.

Objective: Risk-reducing bilateral salpingo-oophorectomy (RRBSO) substantially reduces ovarian cancer risk in women with pathogenic gene variants and is generally recommended by age 34-45 years. Natural menopause is a vulnerable period for mood disturbance, but the risk of depression and anxiety in the first 12 months after RRBSO and potential modifying effect of hormone therapy are uncertain.

Methods: Prospective controlled observational study of 95 premenopausal women planning RRBSO and a Comparison group of 99 premenopausal women who retained their ovaries,- 95% of whom were at population level risk of ovarian cancer.

Family history of non-communicable diseases and associations with weight and movement behaviours in Australian school-aged children: a prospective study.

Objective: To assess differences in weight status and movement behaviour guideline compliance among children aged 5-12 years with and without a family history of non-communicable diseases (NCDs).

Design: Prospective.

Setting And Participants: Women born between 1973 and 1978 were recruited to the Australian Longitudinal Study on Women's Health (ALSWH) via the database of the Health Insurance Commission (now Medicare; Australia's universal health insurance scheme).

Associations between feeding practices in infancy and fruit and vegetable consumption in childhood.

A diet rich in fruits and vegetables may reduce the risk of chronic diseases. However, in many countries, the majority of children do not eat the recommended quantities of fruits and vegetables. The present study aimed to understand associations between feeding practices in infancy (breast-feeding and first complementary food) and fruit and vegetable consumption in childhood (frequency and variety).

Military Personnel Ratings of a Deployment and Their Positive and Negative Deployment Experiences.

Introduction: There is limited investigation of how military personnel evaluate their deployment experiences. An understanding of their perceptions would help unit psychologists to advise commanders on ways to improve the deployment experience (and therefore mental well-being) of personnel. This study examined the interplay between deployment overall ratings, personnel characteristics and positive and negative deployment experiences in aid of such understanding.

Testing the role of the timing and chronicity of maternal depressive symptoms in the associations with child behaviour and development.

Background: There is debate regarding whether the association between maternal depressive symptoms (MDS) and child outcomes is due to the timing or chronicity of symptoms.

Objectives: To investigate whether critical periods, sensitive periods, or accumulation models provided the best explanation for the association between MDS and children's behaviour and development.

Methods: Data on mothers (N = 892) were collected from 1996 to 2015 as part of the Australian Longitudinal Study on Women's Health, a prospective longitudinal epidemiological study.

How rates of perinatal mental health screening in Australia have changed over time and which women are missing out.

Objectives: To report rates of perinatal mental health screening from 2000 to 2017 and investigate factors associated with not being screened both antenatally and postnatally more recently (2013-2017).

Methods: A longitudinal community-based study of self-reported perinatal mental health screening with a national sample of 7,566 mothers from the Australian Longitudinal Study on Women's Health reporting on 9,384 children. The main outcome measure was whether mothers were asked about their emotional wellbeing by a health professional, including completing a questionnaire.

Which Australian Women Do Not Exclusively Breastfeed to 6 Months, and why?

Background: Rates of exclusive breastfeeding in Australia lag behind international targets. Reasons for non-exclusive breastfeeding are poorly understood.

Research Aims: To describe demographic profiles of participants reporting different feeding practices, and reasons for not exclusively breastfeeding to 6 months.

Not All Play Equipment Is Created Equal: Associations Between Equipment at Home and Children's Physical Activity.

Background: Play equipment at home could be targeted in interventions to increase children's physical activity (PA), but evidence is mixed, potentially because current methods do not reflect children's lived experience. This study investigated associations between combinations of equipment and PA.

Methods: Data were from the Mothers and their Children's Health study and the Australian Longitudinal Study on Women's Health.
