Validity and reproducibility of a food frequency questionnaire for dietary factors related to colorectal cancer

Dietary factors play a major role in the development of colorectal cancer. This study evaluated the reproducibility and validity of a 109-food item Food Frequency Questionnaire (FFQ) to measure the consumption of foods and nutrients related to the development of colorectal cancer in a population aged ≥50 years in Flanders, Belgium. A semi-quantitative FFQ was administered two times in a period of two weeks to evaluate reproducibility (FFQ1 and FFQ2). The validity of the FFQ was assessed by comparing FFQ1 against the 3-day diary method (3 DD). A total of 162 respondents (mean age 57.5 years) provided data for the FFQ, of whom 156 also participated in the validity assessment. Mean differences in the intake of foods and nutrients between FFQ1 and FFQ2 were, overall, small and statistically insignificant. However, a higher estimation was observed by FFQ1 as compared to the 3-DD method for the majority of food groups and nutrient intake in the validity assessment. A systematic mean difference (g/day) was observed for eight food groups in the Bland–Altman agreement test; the largest was for fruit intake. Regarding the nutrients, a systematic mean difference was observed in calcium, fat, and vitamin D intake. Overall, the reproducibility of the FFQ was good, and its validity could be satisfactory for estimating absolute food and nutrient intakes and ranking individuals according to high and low intake categories.

2015 Nutrition country profile: Belgium

The 193 individual country profiles capture the status and progress of all UN Member States, and the 80+ indicators include a wealth of information on child, adolescent and adult anthropometry and nutritional status, in addition to intervention coverage, food supply, economics, and demography. This tool is particularly useful for nutrition champions at the country-level, as it presents a wide range of evidence needed to assess country progress in improving nutrition and nutrition-related outcomes.

Modelling Adaptation to Climate Change in Agriculture

2014Ignaciuk A; Mason-D’Croz, Daniel
Details

Modelling Adaptation to Climate Change in Agriculture

This paper investigates how climate change can affect agricultural production and proposes some adaptation measures that could be undertaken to mitigate the negative effects of climate change while enhancing the positive ones. The paper stresses the importance of planned adaptation measures and highlights possible strategies for reducing risk and improving resilience. To quantify the possible effects of climate change and the effects of adaptation measures this study uses the International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT). The analysis first explores the potential effects of climate change on yields and prices. It then goes on to analyse the potential impacts of two distinctive sets of adaptation strategies on yields, prices, and food security, namely: i) research and development (to develop new crop varieties that are better suited to changed climate conditions) and ii) changes in irrigation technology. Last, the analysis in this paper estimates the public and private investment needs in research and development (R&D) for developing new crop varieties, and further develops estimates of the cost of improving irrigation technologies in OECD countries.

Trade Fragmentation and Global Food Security: Rethinking Partnerships in a Changing Landscape

Increasing geopolitical tensions and conflicts are contributing to a more fragmented trading system and a rising focus on national food self-sufficiency. At the same time, climate pressures highlight the risk of relying solely on domestic food production to achieve food security and resilience. These intersecting pressures—conflict-induced disruptions in global markets and unfavorable weather conditions—pose a […]
