Career Summary
Biography
Research interests and vision:
- Dr Jenna Hollis is a dietitian and public health researcher with a passion for improving maternal and child health.
- Her research investigates modifiable maternal health behaviours (e.g. eating behaviours, physical activity, smoking, alcohol, breastfeeding) around the life stage of pregnancy associated with an increased risk of pregnancy and birth complications and long term chronic disease for mothers and their children.
- 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.
Current research:
- As a Clinical and Health Services Research Fellow (2021-2024) with the University of Newcastle and Hunter New England Local Health District (HNE LHD) Population Health, she leads the gestational weight gain stream (related to nutrition and physical activity behaviours) in a team of practitioners and researchers in the conduct of practice-change interventions to improve antenatal care providers delivery of evidenced-based care for health behaviours.
- Partnering with HNE LHD Maternity Services (Australia) and the University of Southampton (UK), she leads a team that is implementing and evaluating a health professional capacity building training initiative (called ‘Healthy Conversation Skills’) to address health professional’s barriers to discussing behaviour change with clients (i.e. low self-efficacy to discuss behaviour change, and insufficient time to provide person-centred approaches). The evidence generated through the project will assist the implementation of Healthy Conversation Skills in other clinical health service and teaching initiatives more broadly to support the current and future healthcare workforce to support patient behaviour change.
Career summary:
- Dr Hollis completed a Bachelor of Nutrition and Dietetics (honours; 2009), and a PhD (July 2014) on diet and physical activity behaviour change for weight gain prevention in women.
- Following PhD completion, she relocated to the United Kingdom as a Research Fellow in Public Health Nutrition at the Rowett Institute of Nutrition and Health, University of Aberdeen, Scotland (2014-15; population dietary assessment methods to measure adherence to national dietary guidelines).
- She was awarded an Australian Government Department of Education and Training Endeavour Research Fellowship to investigate the predictors of maternal and child health through a preconception birth cohort at the Medical Research Council Lifecourse Epidemiology Unit, University of Southampton, UK (2015-2016), where she is still a Visiting Research Fellow.
- Returning to Australia, she strategically undertook a NSW Health appointment (2016-19) to gain experience in population health service delivery and research translation.
- Through successive research fellow appointments (Hunter Medical Research Institute Research Fellow in Public Health (2019-21); HNE LHD Clinical and Health Service Research Fellow (2021-24)), she leads the gestational weight gain and communication skills research streams involving researchers and practitioners in the conduct of practice-change interventions to improve antenatal care providers delivery of evidenced-based care.
Significant achievements:
- Dr Hollis’ research excellence is recognised by receipt of 7 awards, 3 scholarships, and 22 successful grants and fellowships (>$1.3 million) from National Health and Medical Research Council, Australian Government Department of Education and Training, Hunter Medical Research Institute, Hunter New England Local Health District and University of Newcastle.
- She has 36 publications (17 lead), including 3 lead-author book chapters on the role of the prenatal and postnatal environment in child obesity. Twenty-four of 32 papers are in Quartile 1 ranked journals (e.g. Medicine, Public Health, Nutrition and Dietetics).
- Her research has been dissemination in 36 conference presentations and 6 invited university/health organisation presentations.
- Jenna is the Conference Organising Co-Chair and Executive Committee Member of the Health in Preconception, Pregnancy and Postpartum Early and Mid-career Researcher Collective (HiPPP EMR-C).
- She was elected as ECR representative (2020-22) and as member-at-large (2022-24) for the International Society of Behavioural Nutrition and Physical Activity (ISBNPA) Executive Committee (2020-22).
- She was awarded Reviewer of the Year for 2017, and subsequent appointment to the Editorial Board, for the International Journal for Behavioural Nutrition and Physical Activity (IJBNPA; 2017-).

It discusses social determinants and equity considerations related to DBM. The double burden of malnutrition occurs at the country level when there is a high prevalence of both under-nutrition and overweight or obesity in at least one population group. The chapter highlights the importance of appropriate nutrition, including breastfeeding and child dietary intakes, to support optimal growth and development in the context of DBM. The economic revolution has impacted both reductions in wasting, stunting, and thinness, as well as increased sedentary behavior and consumption of nutrient-poor ultra-processed foods that are high in fat, sugar, and salt. Breastfeeding presents potential intervention opportunities for double-duty actions given the various health benefits and protective effects that breastfeeding brings to both mother and infant. The chapter concludes with a discussion on potential new opportunities for intervention.

In Australia, the Department of Health pregnancy care guidelines recommend women be offered routine weighing and receive brief nutritional and physical activity support during antenatal care visits. Women gaining weight outside the Institute of Medicine (IOM)¿s weight gain reference values are further recommended to be referred to a dietitian. However, professional and organizational barriers, including an absence of weight gain referral pathways and limited workforce resources, exist with the translation and scaling of these recommendations into practice. This study aimed to explore patterns of GWG among a cohort of Australian pregnant women and to determine if pregnancy weight gains of above or below 2 kg or 5 kg in the second and third trimester can be used to predict total GWG outside recommendations. Sensitivity, specificity, negative, and positive likelihood ratios were calculated. The most predictive time point was 24 weeks¿ gestation using the minimum weight change parameter of +/-2 kg, demonstrating reasonable sensitivity (0.81, 95% CI 0.61¿0.83) and specificity (0.72, 95% CI 0.61¿0.83), resulting in 55% (n = 72/131) of the cohort qualifying for dietetic referral. Given the current health service constraints, a review of dietetic services within maternity care is warranted.

Healthy Conversation Skills (HCS) training enhances health professionals¿ communication skills and ability to empower and motivate people in health behaviour change. Guided by the Theoretical Domains Framework (TDF), this¿study examined the impact of HCS training on health professional barriers to conducting behaviour change conversations in both clinical and non-clinical settings. Secondary aims were to i) identify health professionals¿ barriers to having behaviour change conversations, and explore the ii) effect of HCS training on health professionals¿ competence and attitudes to adopting HCS, iii) feasibility, acceptability and appropriateness of using HCS in their clinical and non-clinical roles, and iv) acceptability and quality of HCS training. Methods: HCS training was conducted in October-November 2019 and February 2020. Pre-training (T1), post-training (T2) and follow-up (T3; 6-10 weeks post-training) surveys collected data on demographics and changes in competence, confidence, importance and usefulness (10-point Likert scale, where 10 = highest score) of conducting behaviour change conversations. Validated items assessing barriers to having these conversations were based on eight TDF domains. Post-training acceptability and quality of training was assessed. Data were summarised using descriptive statistics, and differences between TDF domain scores at the specific time points were analysed using Wilcoxon matched-pairs signed-rank tests. Results: Sixty-four participants consented to complete surveys (97% women; 16% identified as Aboriginal), with 37 employed in clinical settings and 27 in non-clinical settings. The training improved scores for the TDF domains of skills (T1: median (interquartile range) = 4.7(3.3-5.3); T3 = 5.7(5.3-6.0), p < 0.01), belief about capabilities (T1 = 4.7(3.3-6.0); T3 = 5.7(5.0-6.0), p <¿0.01), and goals (T1 = 4.3(3.7-5.0); T3 = 4.7(4.3-5.3), p < 0.01) at follow-up. Competence in using ¿open discovery questions¿ increased post-training (T1 = 25% of responses; T2 = 96% of responses; T3 = 87% of responses, p < 0.001), as did participants¿ confidence for having behaviour change conversations (T1 = 6.0(4.7-7.6); T2 = 8.1(7.1-8.8), p <¿0.001), including an increased confidence in having behaviour change conversations with Aboriginal clients (T1 = 5.0(2.7-6.3); T2 = 7.6(6.4-8.3), p <¿0.001). Conclusions: Provision of additional support strategies to address intentions; memory, attention and decision processes; and behavioural regulation may enhance adoption and maintenance of HCS in routine practice. Wider implementation of HCS training could be an effective strategy to building capacity and support health professionals to use a person-centred, opportunistic approach to health behaviour change.

Despite their potential, the effectiveness of DHIs are thought to be dependent, in part, on user engagement. However, the relationship between engagement and the effectiveness of dietary DHIs is not well understood. The aim of this review is to describe the association between DHI engagement and dietary intake. A systematic search of four electronic databases and grey literature for records published before December 2019 was conducted. Studies were eligible if they examined a quantitative association between objective measures of engagement with a DHI (subjective experience or usage) and measures of dietary intake in adults (aged = 18 years). From 10,653 citations, seven studies were included. Five studies included usage measures of engagement and two examined subjective experiences. Narrative synthesis, using vote counting, found mixed evidence of an association with usage measures (5 of 12 associations indicated a positive relationship, 7 were in-conclusive) and no evidence regarding an association with subjective experience (both studies were inconclusive). The findings provide early evidence supporting an association between measures of usage and dietary intake; however, this was inconsistent. Further research examining the association between DHI engagement and dietary intake is warranted.

The primary aim of this study was to assess the primary school adherence to a mandatory state-wide healthy canteen policy 12¿months after an effective multi-strategic implementation intervention concluded. Methods: Primary schools were randomised to (a) a 12-14¿months multi-strategic intervention or (b) no-intervention (control). The intervention aimed to improve implementation of a state-wide canteen policy by encouraging schools to remove unhealthy food and beverages (classified as ¿¿red¿¿ or ¿¿banned¿¿) from canteen menus and replace with healthy items (classified as ¿¿green¿¿). No implementation support was provided to either group by the research team between the 12 and 24¿months data collection period. Results: Seventy schools participated, of which 56 schools were assessed at 24-month follow-up. Intervention schools were less likely to have a menu which contained ¿¿red/banned¿¿ items at 24-month follow-up (RR¿=¿2.28; 95% CI: 1.18-4.40; P¿=¿0.01). Intervention schools, however, were not more likely than controls to have a menu which contained >50% ¿¿green¿¿ items at 24-month follow-up (RR¿=¿1.29; 95% CI: 0.98-1.70; P¿=¿0.10). Intervention schools were more likely to adhere to both policy components (no red/banned items and >50% green items on the menu) than control schools (RR¿=¿2.61; 95% CI: 1.29-5.29; P¿=¿0.006). Among intervention schools that were fully adherent to the policy following implementation support (12-month post baseline), all were also adherent at the 24-month follow-up. Conclusion: The intervention was effective in achieving long-term school adherence to a state-wide canteen policy at 24-month follow-up. So what?: The findings suggest that sustained improvements in implementation of school nutrition policies is possible following a period (12¿months) of comprehensive implementation support.

Postpartum weight retention in the childbearing years can substantially alter a woman's weight gain trajectory, with several potential contributing factors identified. Most research has relied on women's recall of pre-pregnancy weight during pregnancy or later, and not considered risk factors in combination. Using measured pre-pregnancy weight, this study aimed to examine the associations of maternal postpartum weight retention with parity, pre-pregnancy BMI, excessive gestational weight gain (GWG), maternal serum vitamin D concentration and dietary Glycaemic Index in early and late pregnancy, and breastfeeding duration, including analysis of the combined impact of potentially modifiable risk factors.Subjects/Methods:Prospective cohort study of 12 583 non-pregnant women aged 20-34 years in Southampton (UK) who were assessed prior to pregnancy, with those who subsequently became pregnant followed up in early and late gestation, and after delivery (n=2559 in the final sample). Linear regression models examined potential predictors of weight retention in adjusted individual and multivariate analyses, and as a risk factor score.Results:Compared with pre-pregnancy weight, 73% of women retained some weight at 6 months postpartum (mean (s.d.): 3.5 (6.2) kg). In the adjusted multivariate model, women who were primiparous, had a lower pre-pregnancy BMI, excessive GWG, a lower early pregnancy vitamin D concentration and breastfed for <6 months had greater weight retention 6 months postpartum (P<0.05 for all variables). For each additional modifiable risk factor (excessive GWG, low vitamin D concentration in early pregnancy and short breastfeeding duration; scale 0-3), women retained an additional 2.49 kg (95% CI: 2.16, 2.82; P<0.001).Conclusions:Having a greater number of modifiable risk factors was associated with greater weight retention 6 months postpartum. Initiatives supporting women to target these risk factors in the years prior to, during and after pregnancy could impact on their weight gain trajectory and later risk of adverse weight-related outcomes.

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.

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.

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.

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.

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.
