In the ALSWH study, attrition is the most common in participants with a lower education, those not born in Australia and those with poorer health or who smoke [ 30 ]. For example, unlike interviews, the people conducting the research may never know if the respondent understood the question that was being asked.
The seven subscales with different maximum points include vegetables 22 pointsfruits 14 pointsprotein foods 14 pointsgrains 14 pointsdairy seven pointsfats one pointand alcohol beverages two points [ 1 ]. Regarding energy intake, those participants belonging to the category of maximum adherence to the MDS showed the highest energy intake whereas those in the category of maximum adherence to the PDP and the AHEI reported lower energy intake.
The DQI scores were compared with component scores, food and nutrient intake, weight status and sociodemographic variables. Figure 1 provides a summary of the methods and results. The original DQI was designed to evaluate adherence to the fourth edition of the Dietary Guidelines for Americans [ 18 ], and each participant achieved one point for each of the following nutrients: Hodge, A.
There was a significant difference in mean weight change across the FAVI tertileswith the third tertile of FAVI gaining the least amount of weight during the six years of followup compared with the other tertiles Table 4.
Intermediate clinical markers that have been examined previously include BMI [ 67 ], percentage body fat and waist circumference [ 68 ], blood pressure [ 6 ], micronutrient intakes [ 9 ], plasma lipids, inflammation markers, serum iron, vitamin B12 and homocysteine [ 1011 ]. Because beans are one of the major sources of calcium in many developing countries in Asia and other regions, intake of dairy foods alone would considerably underrepresent true intakes of calcium-rich foods in developing countries.
This variable was categorized into quintiles. In this study, we created a tool called the Diet Quality Index-International DQI-I for global monitoring and exploration of diet quality across countries.
Sibbritt, A. Estimated micronutrient intakes and number of servings consumed were described according to DQI-I quartiles. Food intake patterns are likely to be more heterogeneous globally than nutrient intake patterns. Survey days were randomly allocated from Monday to Sunday and were almost equally balanced across the 7 d of the week for each sampling unit.
Items such as pasta, rice, muesli, porridge and breakfast cereals were considered as cereals, and servings per week was asked.
For fruits, vegetables, and snack foods, consumption in the past seven days was obtained. Using an a-priori approach, a diet index provides a summary of dietary patterns as a composite score according to predefined criteria of what constitutes a healthy or unhealthy diet [ 56 ].
Also, because the questions are so specific to what the researchers are asking, the information gained can be minimal. Other confounding factors such as marital status and employment status were also explored but not included in the final models because their inclusion in the regression models did not substantially change the reported associations.
Ireland, D. Examples of a standard serving size were provided for each question. As an individual-level indicator, it can be paired with individual health outcomes or demographic information, such as religion, age, sex, education, or any other characteristics of interest Yun et al. The strengths of this study include the use of a healthy representative sub-sample derived from ALSWH population, with an adequate followup period.
The study followed a three-stage cluster randomised sampling method. O'Dea et al.
