Introduction: The use of email and website as channels for workplace health
information delivery is not fully explored. This study aims to describe the
rationale, design, and baseline findings of an email-linked website intervention
to improve modifiable cancer risk factors. Methods: Employees of a Malaysian
public university were recruited by systematic random sampling and randomised
into an intervention (n=174) or control group (n=165). A website was developed
for the intervention and educational modules were uploaded onto the website.
The intervention group received ten consecutive weekly emails with hypertext
links to the website for downloading the modules and two individual phone
calls as motivational support whilst the control group received none. Diet,
lifestyle, anthropometric measurements, psychosocial factors and stages of change
related to dietary fat, fruit and vegetable intake, and physical activity were
assessed. Results: Participants were predominantly female and in non-academic
positions. Obesity was prevalent in 15% and 37% were at risk of co-morbidities.
Mean intake of fats was 31%, fruit was ~1 serving/day and vegetable was <1
serving/day. Less than 20% smoked and drank alcohol and about 40% were
physically inactive. The majority of the participants fell into the Preparation
stage for decreasing fat intake, eating more fruit and vegetables, and increasing
physical activity. Self-efficacy and perceived benefits were lowest among participants in the Precontemplation/Contemplation stage compared to the Preparation
and Action/Maintenance stages. Conclusion: Baseline data show that dietary and
lifestyle practices among the employees did not meet the international guidelines
for cancer prevention. Hence the findings warrant the intervention planned.

OBJECTIVES: To describe the development and validation of a cancer awareness questionnaire (CAQ) based on a literature review of previous studies, focusing on cancer awareness and prevention.
MATERIALS AND METHODS: A total of 388 Chinese undergraduate students in a private university in Kuala Lumpur, Malaysia, were recruited to evaluate the developed self-administered questionnaire. The CAQ consisted of four sections: awareness of cancer warning signs and screening tests; knowledge of cancer risk factors; barriers in seeking medical advice; and attitudes towards cancer and cancer prevention. The questionnaire was evaluated for construct validity using principal component analysis and internal consistency using Cronbach's alpha (α) coefficient. Test-retest reliability was assessed with a 10-14 days interval and measured using Pearson product-moment correlation.
RESULTS: The initial 77-item CAQ was reduced to 63 items, with satisfactory construct validity, and a high total internal consistency (Cronbach's α=0.77). A total of 143 students completed the questionnaire for the test-retest reliability obtaining a correlation of 0.72 (p<0.001) overall.
CONCLUSIONS: The CAQ could provide a reliable and valid measure that can be used to assess cancer awareness among local Chinese undergraduate students. However, further studies among students from different backgrounds (e.g. ethnicity) are required in order to facilitate the use of the cancer awareness questionnaire among all university students.
As a by-product of tropical fruit juice industry, passion fruit peel is a valuable functional food. It is rich in antioxidants. To determine its potential antioxidant properties of passion fruit peel, this study aimed to evaluate the effect of extraction conditions on total phenolic content and antioxidant activity.
