Associate Professor Rozanne Kruger

Associate Professor in Dietetics and Human Nutrition

School of Sport, Exercise and Nutrition

Background:

Currently: Associate Professor in Dietetics and Human Nutrition at IFNHH, Albany

Major Leader and course coordinator of the MSc in Nutrition and Dietetics

Previously: Senior Lecturer and Head of the Food and Nutrition Section, Department of Consumer Science at the University of Pretoria in South Africa.

 I completed my dietetic training (BSc Dietetics and PG Dip Hosp Diet) and I am a registered dietitian in both South Africa and New Zealand. My MSc research was quite extensive on the nutritional status and feeding practices of one to three year-olds, including a large component of some of the first qualitative work done in nutrition. In my PhD (Human Nutrition) I investigated the determinants of obesity in 10-15 year old children (THUSABANA study) in South Africa. Subsequently I have been involved in research on infant feeding practices, and preschooler caregiver capacity and implementing food-based approaches.  I have continued SA research collaboration and publications utilizing my specific expertise in dietary diversity and implementing food-based approaches as solutions.  In NZ I have been involved in research in iron status of young women, omega 3 PUFA status assessment, and increasing omega 3 PUFA status from salmon versus salmon oil capsules, kiwi fruit and markers of metabolic health.

My current research is focused on body composition profiling and obesity prevention relating to food and nutrition issues in NZ populations.  I am currently PI of a large study [women’s EXPLORE (Examining the Predictors Linking Obesity-Related Elements) study] in young NZ, Maori and Pasifika women where we are investigating hidden and apparent fat profiles and the predictors of these profiles in terms of metabolic health, dietary aspects, taste perception and physical activity and the role of micro RNAs.

Over the years I have gained valuable experience in conducting human intervention trials, and I am also a qualified body composition operator (BodPod), DXA technician, and an ISAK level 1 anthropometrist. My expertise in the Nutrition and Dietetics Research team at Massey University is in designing dietary interventions, and all aspects of dietary and anthropometric assessments.

Main interests

Designing dietary interventions, and all aspects of dietary, anthropometric and body composition assessments; Determinants of obesity; Dietary Diversity, Qualitative research focused on dietary intake and nutrition behaviour; Implementing food-based approaches as solutions; Omega 3 PUFA intakes & status; Markers of metabolic health.

Future opportunities

Focus on a preventive approach investigating the related predictors of obesity to guide NZ practice. We have unique capability in body composition assessment with DEXA, BodPod, and BIA and qualified anthropometrists. We have expertise and facilities for human intervention trials, biomarker and cell analysis and we can add the bonus of dietetic skill and expertise in qualitative research to the mix. We are also skilled in developing and validating new and innovative assessements, and looking at unique ways to overcome current health issues.

I joined the IFNHH in July 2007. I completed my undergraduate training, dietetic training and MSc at the University of Pretoria, and my PhD at the North West University, South Africa. Prior to arriving in New Zealand, I was Head of the Food and Nutrition Section at the University of Pretoria. I'm a registered dietitian and Discipline Leader for the MSc Nutrition and Dietetics programme at Massey University. Research areas include dietary and nutritional assessment, dietary diversity and pattern assessment, clinical dietetics/nutrition determinants of obesity, and food-based approaches as solutions (omega 3 PUFA status; kiwifruit and markers of metabolic/respiratory health).
