PhD Title: PhD in Public Health

Supervisor(s): Dr Nik Anni Afiqah Hj Mohd Tuah, Dr Suwarni Diah and Dr Hajah Norhayati Haji Kassim

About the PhD:

I worked on the development of a mobile application called ‘Health Coach’, with content focus on dietary and physical activity information. The development and designed of Health Coach were informed by behavioural change theories, academics, health professionals and intended users. In my thesis, I determine the effectiveness of Health Coach in changing dietary and physical activity behaviour as a strategy for obesity prevention in overweight and obese adolescents in secondary schools in Brunei. Research in mobile health (m-Health) is a relatively new field and evidences are subsequently emerging. This research is the first-evidence based apps study within the Brunei context in targeting overweight and obese adolescents for obesity prevention in Brunei.

Key words: 

human nutrition and metabolism, dietary and nutrition analysis, nutrition policy, development of mobile application, m-Health, e-Health, public health, adolescents

I have always been interested in food and nutrition, hence, my undergraduate and postgraduate training have been focused on how food and nutrition make huge implications to human health. After my MSc, I spent months of internship in the Health Promotion Centre of the Ministry of Health, Brunei, and this experience opened up my interest in the importance of population health, particularly in obesity prevention. Working with the health professionals at the Centre, I have learnt how complex it is, in real-life settings, to reach, disseminate, and educate health to the public. My research interest is in developing innovative ways to intervene and prevent overweightness and obesity through the dimensions of diet and physical activity.
