Public Health Dietitians addresses a range of key nutrition or diet related health issues, including obesity, Type 2 Diabetes, and cardiovascular diseases.
Obesity is defined as having a Body Mass Index (BMI) greater than or equal to 30. In New Zealand, 31% of adults, or 11% of children, are obese (MOH, 2015). The epidemic is caused by a lack of energy balance, where more calories are consumed than calories used (World Health Organisation, 2015). This comes from over consumption of food and drinks, especially those high in fat and sugar, and from a lack of physical activity due to an increasingly sedentary lifestyle. Increasingly, there is a global trend towards high fat, high energy dense food (World Health Organisation, 2015). While excessive food consumption and lack of exercise are behavioral choices, there are a number of environmental risk factors such as the heavy promotion of unhealthy food and lack of government policies that contribute to the rising rates of obesity (New Zealand Medical Association (NZMA), 2014). Obesity also leads to other health issues, including non-communicable diseases like type 2 diabetes, heart diseases, stroke, and cancer and psychological problems like depression (NZMA, 2014). Type 2 Diabetes is a chronic illness, where obesity is the main preventable risk factor. Over 240,000 people in NZ is diagnosed with …show more content…

Therefore, diet is an important lifestyle factor that significantly affects health of New Zealanders. These issues also have significant economic impacts. In 2006, health care cost in NZ related to obesity was $624million, or 4.5% of total health care expenditure (Lal, Moodie ,Ashton, Siahpush & Swinburn, 2012). NZ’s increasingly obesogenic society and ageing population means rates of obesity, non-communicable diseases like diabetes and cardiovascular diseases are rising (NZMA, 2014). These diseases impact both an individual’s quality of life, and also place a considerable financial strain on the healthcare system. Therefore, they are important public health issues that need to be addressed in New
