Primary schools sought for health and wellness week study
More children are sought for New Zealand’s first-ever comprehensive investigation measuring the connection between a range of health indicators and the risk of diabetes or heart disease, also known as cardio-metabolic health.
School of Sport, Exercise and Health PhD candidate Nick Castro’s study involves a health and wellness week for children aged eight to 10 years. It addresses these health indicators that include good eating habits, daily exercise, staying fit and getting enough sleep. The study will take place in primary schools at Wellington, Christchurch and Dunedin.
“Although cardio-vascular disease [closely related to cardio-metabolic health] is typically associated with middle or old age the process often initiates in childhood,” Mr Castro says.
The study involves a one-week process. Children are tested on such measures as their blood pressure, body composition (height, weight, hip, waist), and sugar and glucose levels. Then, later in the week, with support from agencies such as the Health Foundation, the entire school is invited to participate in a health and wellness day comprising similar tests, games and activities.
The Pre-Adolescent Cardio-Metabolic Associations and Correlates or PACMAC programme will collectively address in one study issues previously only investigated separately, Mr Castro says.
“While commonly cited causes of obesity include declining physical activity and fitness levels, poor nutrition and poor sleep habits, no study in New Zealand has comprehensively assessed all these components together in primary school-aged children.”

As he approaches the halfway point of his research, Mr Castro is calling on more schools and their pupils to participate in the study.
“The research outcomes from the PACMAC study will help inform health professionals, education curriculum developers and children health policy guidelines as to the most effective and cost efficient way to make an impact on the deteriorating health of children in New Zealand.”
At present New Zealand is always ranked among the top five countries with the highest rates of childhood obesity, he says. A contributory factor could be a child’s lack or quality of sleep, which can contribute to obesity, high blood pressure and decreased insulin sensitivity due to changes in the levels of appetite regulating hormones released during the sleep cycle.
In the short-term the findings will help clarify targets for reducing obesity and improving cardio-metabolic health among New Zealand children. Longer term, he says the study will look to promote larger scale research focusing on potential ethnic differences, changes across age groups, international comparisons and the implications for healthcare systems.
