The MINI Study

This study will monitor the mother’s health by assessing her nutrient status, thyroid function and general health. How a mother’s health status might affect her baby’s development during early life is important. The three nutrients being studied are iodine, selenium, and iron. Understanding these nutrients will help to provide better health care to future mothers. This leads to greater knowledge about the health and wellbeing of all mothers and their infants.

Who are we looking for?
•    healthy women over the age of 16
•    either in the late stage of pregnancy or having just given birth.

The VIDOMA Study - Autism in Children

The study is nicknamed the VIDOMA study, short for VItamin D and OMega-3 in Autism.

Children with ASD often have deficiencies in their diet due to physical and behavioural issues related to the condition. Some of the nutrients which can be deficient in children with ASD are known to affect brain development and function. The two nutrients that this study is going to investigate are vitamin D and omega-3.

Recruitment for this study has now been completed. Thank you to all those that took, or are currently taking part. A summary of the results will be posted here once completed.

What does your body profile say about you?

We are looking for women of all shapes and sizes to take part in the women’s “EXPLORE” study. We want to understand how different body weight and body fat profiles are related to risk for chronic disease in women. We also want to understand how diet and physical activity patterns may impact these profiles and more specifically, how diet and activity may affect small molecules in the blood associated with body fat usage and storage.

Preschoolers & Vitamin D Study - Te Ra Whakaora

We mostly get Vitamin D from the sun, which is very important for building strong bones and maintaining good health. Researchers know something about the vitamin D status of New Zealand adults, and a little about newborn babies, but we know very little about the vitamin D levels of our preschoolers.

We will be able to create a simple questionnaire-type tool from the data collected in this study which health professionals can use to decide if a child is at risk of vitamin D deficiency. This means they can be identified early, before their health is potentially affected.

Data collection is now complete. A summary of the results will be posted here soon.
