Collective Title

Master of Science in Nutrition and Dietetics Research Reports 2019


Abstract Background: Various factors such as sleep quality and amount and food intake can have an impact on quality of life in terms of the amount of stress or fatigue that an individual experiences as an outcome. Food tracking has been commonly used as a tool for weight loss. Yet, current research has been looking at other possible advantages related to food tracking.

Objective: To examine the effects of food and sleep tracking on health-related quality of life with respects to sleep quality and quantity, stress, and fatigue, in adults aged 18 years or older.

Methods: Participants completed the Perceived Stress Scale and Fatigue Symptom Inventory questionnaires before and after a 7-day food and sleep tracking period, via the HealthWatch 360 application. An optional interview was conducted with 20 participants and summarized into four themes.

Results: There was a nonsignificant improvement in overall sleep amount (p=0.073) over 7 days, when compared to day 1 as baseline. When stratified by gender, there was a significant improvement in overall sleep amount for females (0.012) but not for males (p=0.321). Results also found that there were significant changes in sleep quality (p=0.582) for males and females. Moreover, there was a slight, nonsignificant, decrease in fatigue and stress over 7 days, (p=0.067) and (p=0.039), respectively.

Conclusion: Food and sleep tracking using the HealthWatch 360 application does not have a significant effect on quality of life in terms of stress, fatigue and sleep. Nevertheless, tracking food intake and sleep may lead to increased accountability.
