ABSTRACT
@#This article aimed to review the design features of web-based or online FFQ developed for adults and statistical analysis used in the validation, comparison, or reproducibility studies. The search identified 863 articles, and 29 studies met the criteria. The number of food list ranges from 12 to 279 items. The food portion size was estimated using images or a standard portion size using household measurement. Web-based FFQ was validated with other dietary assessment tools, Block FFQ and biomarker. Comparison study of web-based FFQ was done using paper-based FFQ and interviewed-administered FFQ. Two studies conducted validation and comparison study using other dietary assessment methods, biomarker and paper-based FFQ. Seven studies conducted reproducibility studies. Overall, webbased FFQs showed acceptable validity with the respective reference method and good reproducibility. Strategies to improve the application of current evidence on best practices in designing and validating a web-based FFQ can improve nutritional epidemiology studies.
ABSTRACT
A balanced dietary intake plays an important role in the prognosis of breast cancer and is one of the modifiable factors in preventing cancer recurrence. This study aims to determine the dietary intake among breast cancer survivors in East Coast of Peninsular Malaysia. A total of 125 breast cancer survivors, aged 37 to 72 years, with mean duration of survivorship of 6.1 ± 3.9 years were recruited from two main referral hospitals in Terengganu and Kelantan. Majority of the respondents were Malay (94.4%) with a mean BMI of 27.7 ± 5.07 kg/m², and were diagnosed with stage II cancer (66.0%). Dietary intake was estimated using a semi-quantitative food frequency questionnaire (FFQ). The results show that the mean daily intake of energy was 1764 ± 378 kcal/day, protein was 72.38 ± 33.6 g/day (16.5% of energy), carbohydrate was 243.0 ± 62.2 g/day (55% of energy) and fat was 55.8 ± 15.6 g/day (28% of energy). Overall, breast cancer survivors in this study had an adequate daily intake of vitamins and minerals according to Malaysian Recommended Nutrient Intakes (RNI) except for dietary fibre (10.6 ± 4.2 g/day), monounsaturated fatty acids (20.7 ± 5.7 g/day), polyunsaturated fatty acids (8.0 ± 2.2 g/day), calcium (561.0 ± 257.1 mg/day), iron (18.3 ± 7.2 mg/day) and potassium (1813.4 ± 531.1 mg/day) which was lower than the recommendation. Meanwhile, intake of sodium (2592 ± 1697 mg/day), protein (80.4 ± 33.6 g/day), saturated fatty acids (26.9 ± 14.2 g/day), vitamin B2 (1.9 ± 1.1 mg/day) and vitamin C (151.1 ± 149.3 mg/day) exceeded the recommendation by 135.0%, 139.0%, 166.9%, 154.6% and 152.0%, respectively. There was no significant difference in dietary intake between cancer survivors who were diagnosed in the past five years and those who were diagnosed more than five years ago (p>0.05) except for fat (p<0.001), saturated fatty acid (p=0.006), monounsaturated fatty acid (p=0.005) and polyunsaturated fatty acid (p=0.003). As a conclusion, breast cancer survivors in East Coast of Peninsular Malaysia had an adequate intake of most nutrients except for dietary fibre, monounsaturated fatty acids, polyunsaturated fatty acids, calcium, iron and potassium which was below the recommendation and sodium, protein, saturated fatty acids, vitamin B2, vitamin C which was above the recommendation. The intakes between long-term and short-term survivors were also comparable showing sustained dietary intake throughout survivorship.
