Career Summary

Biography

Research interests and vision:

  • Dr Jenna Hollis is an Early Career Researcher with a passion for improving maternal and child health.
  • Her research investigates modifiable maternal health behaviours in pregnancy and postpartum (e.g. obesity, gestational weight gain, eating habits, smoking, alcohol, breastfeeding) associated with an increased risk of pregnancy/birth complications and long term chronic disease for the mother and child.
  • Her research vision is to protect the health of women, and ensure children start life on an optimal health trajectory, by integrating nutrition and weight gain evidence in early life (i.e. preconception, pregnancy and infancy) to health service policy and practice.

Significant achievements:

  • Jenna has 20 publications (12 lead; upward trajectory with 6 in 2016), with 2 book chapters on the prenatal environment. Thirteen of 18 papers are in Q1 ranked journals (eg. for Nutrition and Dietetics, Public Health) including International Journal of Obesity, British Journal of Nutrition, and Maternal and Child Nutrition. She has 18 conference abstracts (12 international, 12 lead) and 2 invited presentations.
  • Her research excellence is recognised by receipt of 3 awards, 3 scholarships, 4 grants / fellowships (CIA totalling $135k) from the Department of Education and Training (Australian Government), Hunter Medical Research Institute (HMRI) and University of Newcastle (UON).
  • She is a member of 4 research societies and a founding committee member of International Society of Behavioural Nutrition and Physical Activity (ISBNPA) Early Career Research (ECR) group, where she assists in co-ordinating regular webinars, conference workshops and e-communications to support the career development of ECRs and PhD students internationally. 
  • She is also on the Editorial Board (2017- ) for the International Journal for Behavioural Nutrition and Physical Activity (IJBNPA), and regularly peer reviews for journals (~2/month) such as IJBNPA, Appetite and British Journal of Nutrition.

Education and training:

  • Dr Hollis is a public health nutrition researcher and dietitian (PhD; Bachelor of Nutrition and Dietetics (Honours I))with 7 years of research and health service delivery experience in dietary assessment methodology, nutritional epidemiology and trials implementation.
  • Her PhD (University of Newcastle, Australia; 2010-2014) investigated the effectiveness of a 12-month health professional intervention (based on Motivational Interviewing) for diet and physical activity behaviour change in non-obese 44-50 year old women soon to transition through menopause. In addition to the 12-month RCT, effect maintenance was assessed over a further 12 month follow-up period. Her thesis can be accessed at: http://nova.newcastle.edu.au/vital/access/manager/Repository/uon:14401

Postdoctoral research:

  • Following her PhD, she moved to the Rowett Institute of Nutrition and Health, University of Aberdeen (Scotland) to take a position as Research Fellow in Public Health Nutrition (2015-2016). She gained experience in dietary assessment methodology and evaluating simplified methods of monitoring population adherence to national dietary guidelines (The Eatwell Plate).
  • In 2015, she secured an international Endeavour Postdoctoral Fellowship (funded by the Australian Government) to investigate predictors of maternal and child health through secondary data analysis of a preconception birth cohort (Southampton Women’s Survey; SWS) at the Medical Research Council Lifecourse Epidemiology Unit (MRC LEU), University of Southampton, UK (2015-16).
  • The project initiated an international collaboration between the University of Newcastle (Australia) and the University of Southampton (UK). The findings will help researchers and health professionals to develop more targeted recommendations and support for expecting mothers during pregnancy, and for women and their children postpartum.

Current research:

  • In November 2016, she commenced a postdoctoral position (Project Officer) at Hunter New England Population Health (Newcastle, Australia) where she is gaining translation and implementation skills through an adolescent physical activity intervention (Physical Activity for Everyone; PA4E1), and a Maternal Alcohol Study to improve health practitioner provision of alcohol support during pregnancy.
  • She continues to collaborate with researchers at the University of Southampton, where she has Visiting Research Fellow status.

© The Authors 2016. Objective To assess the relative validity of the latest version of the Scottish Collaborative Group (SCG) FFQ (version 6.6) in adults living in Scotland. Design A cross-sectional validation study. Participants completed the self-administered, 169-item SCG FFQ followed by a 7 d, non-weighed food diary. Energy and energy-adjusted macronutrients and micronutrients were examined for relative validity through Spearman's correlation, the percentage of classification into thirds of intake, Cohen's weighted kappa (¿ w) and Bland-Altman analysis. Setting General population living in Scotland. Subjects Ninety-six adults aged 18-65 years. Results Spearman's correlation coefficients ranged from 0·21 (retinol) to 0·71 (Mg). A median of 52 % of adults were correctly classified into thirds of intake (range: 42 % (PUFA, MUFA and Fe) to 64 % (percentage energy from carbohydrates)) and 8 % were grossly misclassified into opposite thirds of intake (range: 3 % (carbohydrates, percentage energy from carbohydrates) to 19 % (thiamin)). Values of ¿ w ranged between 0·20 (PUFA, ß-carotene) to 0·55 (percentage energy from carbohydrates). In the Bland-Altman analysis, the smallest limits of agreement, when expressed as a percentage of the mean intake from the FFQ and food diary, were seen for the main macronutrients carbohydrates, fat and protein. Conclusions As in the previous validation study more than 10 years ago, the FFQ gave higher estimates of energy and most nutrients than the food diary, but after adjustment for energy intake the FFQ could be used in place of non-weighed food diaries for most macronutrients and many micronutrients in large-scale epidemiological studies.

© 2016 John Wiley & Sons Ltd There is a lack of knowledge and understanding of the term exclusive breastfeeding (EBF) among health professionals. The purpose of this review was to examine the best available literature on mothers' understanding of the term EBF. A systematic search of eight electronic databases (Medline, Embase, CINAHL, CDSR, CENTRAL, Cab Abstracts, Scopus and African Index Medicus) was conducted (Protocol registration in PROSPERO: CRD42015019402). All study designs were eligible for inclusion. Studies were included if they: (1) involved mothers aged 18 years or older; (2) assessed mothers' knowledge/understanding/awareness of the term ¿EBF¿; (3) used the 1991 WHO definition of EBF and (4) were published between 1988 and 2015. Two reviewers retrieved articles, assessed study quality and performed data extraction. Of the 1700 articles identified, 21 articles met the inclusion criteria. Quantitative findings were pooled to calculate a proportion rate of 70.9% of mothers who could correctly define EBF, although the range varied between 3.1 and 100%. Qualitative findings revealed three themes: (1) EBF was understood by mothers as not mixing two milks; (2) the term ¿exclusive¿ in EBF was incorrectly understood as not giving breast milk and (3) mothers believing that water can be given while exclusively breastfeeding. Research investigating aspects of self-reported EBF may consequently be unreliable. A standardised tool to assess mothers' knowledge of EBF could provide more accurate data. Public health campaigns should emphasise EBF to target mothers, while addressing the education of health professionals to ensure that they do not provide conflicting advice.

© 2017 The Author(s). Background: Schools play an important role in physical activity promotion for adolescents. The systematic review aimed to determine the proportion of secondary (middle and high) school physical education (PE) lesson time that students spend in moderate to vigorous physical activity (MVPA), and to assess if MVPA was moderated by school level (middle and high school), type of physical activity measurement and type of PE activities. Methods: A systematic search of nine electronic databases was conducted (PROSPERO2014:CRD42014009649). Studies were eligible if they were published between 2005 and 2014; written in English; assessed MVPA in PE lessons of secondary (middle and high) school students; and used a quantitative MVPA measure (i.e., accelerometry, heart rate monitoring, pedometers or observational measures). Two reviewers examined the retrieved articles, assessed risk of bias, and performed data extraction. Random effects meta-analysis was used to calculate a pooled estimate of the percent of PE lesson time spent in MVPA and to assess moderator effects where data allowed. Results: The search yielded 5,132 potentially relevant articles; 28 articles representing 25 studies (7 middle and 18 high school) from seven countries were included. Twelve studies measured MVPA through observational measures, seven used accelerometers, five used heart rate monitors and four used pedometers (including three studies using a mix of measures). Meta-analysis of 15 studies found that overall, students spent a mean (95% CI) of 40.5% (34.8-46.2%) of PE in MVPA. Middle school students spent 48.6% (41.3-55.9%) of the lesson in MVPA (n=5 studies) and high school students 35.9% (28.3-43.6%) (n=10 studies). Studies measuring MVPA using accelerometers (n=5) showed that students spent 34.7% (25.1-44.4%) of the lesson in MVPA, while 44.4% (38.3-50.5%) was found for lessons assessed via observation (n=9), 43.1% (24.3-61.9%) of the lesson for a heart rate based study, and 35.9% (31.0-40.8%) for a pedometer-measured study. Conclusions: The proportion of PE spent in MVPA (40.5%) is below the US Centre for Disease Control and Prevention and the UK Associations for Physical Education recommendation of 50%. Findings differed according to the method of MVPA assessment. Additional strategies and intervention research are needed to build more active lesson time in PE.

© 2015 Elsevier Inc. Objective: To examine elementary school students' moderate-to-vigorous physical activity (MVPA) levels during physical education (PE) lessons. Methods: A systematic search of nine electronic databases was conducted (PROSPERO2014:CRD42014009649). Studies were eligible if they were in English; published between 2005-April 2014; assessed MVPA levels in PE lessons of elementary school children (aged four-12 years); and used an objective MVPA measure. Two reviewers retrieved articles, assessed risk of bias, and performed data extraction. The findings were synthesised using a meta-analysis. Results: The search yielded 5132 articles. Thirteen studies from nine countries met the inclusion criteria. Eight studies measured MVPA through observational measures, five used accelerometry and one used heart rate monitoring. The percentage of PE lesson time spent in MVPA ranged between 11.4-88.5%. Meta-analysis of seven studies (direct observations; 4 accelerometers) found that children spent a mean (95% CI) 44.8 (28.2-61.4)% of PE lesson time in MVPA. When measured using direct observation and accelerometers, children spent 57.6 (47.3-68.2) and 32.6 (5.9-59.3)% of PE lesson time in MVPA, respectively. The review has limitations; the search strategy was restricted to studies in English; theses, dissertations and conference abstracts were excluded; and six studies that provided insufficient data were excluded from the meta-analysis. Conclusion: MVPA levels during elementary school PE lessons do not meet the United States Centre for Disease Control and Prevention and the United Kingdom's Association of Physical Education recommendation (50% of lesson time), but is higher than estimated in the previous review (34.2%). Interventions to increase MVPA in PE lessons are needed.

Background: Adolescence is a recognised period of physical activity decline, particularly among low-income communities. We report the 12-month (midpoint) effects of a 2-year multicomponent physical activity intervention implemented in disadvantaged secondary schools. Methods: A cluster randomised trial was undertaken in 10 secondary schools located in disadvantaged areas in New South Wales, Australia. Students in Grade 7 were recruited, with follow-up in Grade 8. The intervention was guided by socioecological theory and included seven physical activity strategies, and six implementation adoption strategies. The primary outcome was mean minutes of moderate-to-vigorous physical activity (MVPA) per day assessed using Actigraph GT3X accelerometers. Outcome data were analysed using repeated measures linear mixed models. Results: At baseline, 1150 (93%) students participated in the data collection (mean age 12 years, 48% boys) and 1050 (79%) students participated at 12-month follow-up. By the 12-month follow-up, the six implementation adoption strategies had been used to support schools to deliver four of the seven physical activity elements. There was a significant group-by-time interaction for mean minutes of MVPA per day in favour of the intervention group (adjusted difference between groups at follow-up=3.85 min, 95% CI (0.79 to 6.91), p=0.01), including significantly more vigorous physical activity (2.45 min, p=0.01), equating to 27 min more MVPA per week. Summary: At 12-month follow-up, the intervention had reduced the decline in physical activity among adolescents from disadvantaged schools. The intervention may assist students to meet physical activity guidelines.

© 2015 Dietitians Association of Australia. Aim: The 40-Something Randomised Controlled Trial (RCT) aimed to determine if a 12-month health professional-led intervention could improve dietary intake and increase physical activity for weight gain prevention in non-obese premenopausal women. Methods: Fifty-four women were randomised to a motivational interviewing intervention (MI) (n = 28; five health professional consultations) or a self-directed intervention (SDI; n = 26; written advice). Weight control behaviours including dietary intake (four-day weighed food record) and physical activity (pedometer steps; minutes spent in light, moderate and vigorous activity; sitting time) were measured at baseline, and at 3 and 12 months. Participants completed a questionnaire containing demographic questions, Short Form 36 and the International Physical Activity Questionnaire at baseline and 12 months. Linear mixed model analyses adjusting for baseline and 3-month behaviour, covariates and interactions were used to test for between-group differences. Results: At 12 months, the MI group had diets significantly more nutrient dense in iron (P = 0.01) and potassium (P = 0.04), and consumed more fruits (P = 0.02) than the SDI women. Women who achieved their weight control goals consumed significantly more daily fruit servings (+0.76 servings/day, P = 0.02) and less meat/meat alternatives (-0.34 servings/day, P < 0.01) than women who did not achieve weight control. The lack of changes in physical activity indicates that more emphasis may need to be placed on promoting physical activity. Conclusions: The findings demonstrated the effectiveness of the 40-Something RCT in improving iron and potassium nutrient density and fruit servings per day in women soon to commence menopause.
