Biography

As a Statistician with the Australian Longitudinal Study on Women's Health, I have a strong interest in modifiable factors that effect the health and well-being of women.

Specific statistical interests include methodological issues associated with longitudinal data analysis, missing data and problems of temporary or permanent attrition.

Research Expertise
Substantial statistical analysis of longitudinal data from the Australian Longitudinal Study on Women's Health (ALSWH) e.g longitudinal relationship of alcohol intake and health; Investigation of other methodological issues such as ways of handling missing data; Validation of scales used in the Australian Longitudinal Study on Womens Health; Assessment of representativeness and attrition in the cohorts of the Australian Longitudinal Study on Womens Health; Assessment of the effectiveness of linkage with the National Death Index.

Teaching Expertise
lectured biostatistics at the master of public health level

Collaborations
Jennifer Powers works within the PRC for Gender, Health and Ageing and collaborates with researchers at the University of Newcastle, the University of Queensland and the University of New South Wales.

Introduction and Aims: To examine women's drinking behaviour relative to Australian guidelines and identify associated factors over the lifespan. Design and Methods: Data came from three prospective cohorts of the Australian Longitudinal Study on Women's Health aged 18-23 (n=14247), 45-50 (n=13715) and 70-75 years (n=12432) when first surveyed in 1996. The same women were re-surveyed at roughly 3-year intervals until 2012. At each survey, four drinking behaviours were based on two guidelines: long-term drinking (no more than two standard drinks per day) and episodic drinking (no more than four standard drinks on an occasion): (i) no risk (within both guidelines); (ii) low episodic risk (less than once a month); high episodic risk (at least once a month); long-term risk (more than two drinks per day regardless of episodic drinking). Results: No risk drinking increased with age, low episodic risk drinking remained almost constant between ages 18 and 39, and high episodic risk drinking declined rapidly. Few women drank at long-term risk. Factors associated with risky drinking varied with age; however, being a past or current smoker consistently increased the risk, and risks for smokers increased with age. Risky drinking was less likely to be practised by women providing care and needing help with daily tasks, or by pregnant women and those living with children. Discussion and Conclusions: Risky drinking behaviour should be addressed in younger women and in those who smoke. Interventions to reduce risky drinking, possibly in combination with reducing smoking, could be offered through general practice centres.

Objective To identify predictors of antenatal alcohol consumption among women who usually consume alcohol. Design Prospective cohort study. Setting Australian Longitudinal Study on Women's Health (ALSWH). Population or Sample A total of 1969 women sampled from the ALSWH 1973-78 cohort. Methods Women were included if they were pregnant in 2000, 2003, 2006 or 2009. The relationship between antenatal alcohol consumption and sociodemographics, reproductive health, mental health, physical health, health behaviours, alcohol guidelines and healthcare factors was investigated using a multivariate logistic regression model. Main outcome measures Alcohol use during pregnancy. Results Most (82.0%) women continued to drink alcohol during pregnancy. Women were more likely to drink alcohol during pregnancy if they had consumed alcohol on a weekly basis before pregnancy (odds ratio [OR] 1.47; 95% confidence interval [95% CI] 1.13-1.90), binge drank before pregnancy (OR 2.28; 95% CI 1.76-2.94), or if they were pregnant while alcohol guidelines recommended low alcohol versus abstinence (OR 1.60; 95% CI 1.26-2.03). Drinking during pregnancy was less likely if women had a Health Care Card (OR 0.63; 95% CI 0.45-0.88) or if they had ever had fertility problems (OR 0.64; 95% CI 0.48-0.86). Conclusions Most Australian women who drank alcohol continued to do so during pregnancy. Prepregnancy alcohol consumption was one of the main predictors of antenatal alcohol use. Alcohol guidelines, fertility problems and Health Care Card status also impacted antenatal alcohol consumption. © 2013 RCOG.
