A accomplished puzzle tells a narrative extra successfully than any particular person piece may by itself, however each piece is critical to finish the picture. That is an analogy for the way the World Vitamin and Well being Atlas—a public useful resource with diet-related well being info for greater than 190 nations spanning throughout 30 years—works. The GNHA has hundreds of contributors, and when extra items are added, the image turns into clearer.
Powered by researchers on the Friedman College of Vitamin Science and Coverage at Tufts and Nestlé Analysis, the GNHA homes massive quantities of knowledge that researchers, college students, practitioners, and well being policymakers can use of their work.
“When researchers and policymakers have entry to a fuller image of dietary patterns, gaps in nutrient consumption, environmental affect, consuming habits and dietary necessities for youngsters and infants,” says Elena Naumova, chair of the Division of Vitamin Epidemiology and Knowledge Science on the Friedman College, “they’ve a greater concept of what and the place sources have to be deployed to advertise wholesome vitamin.”
The GNHA was created to foster cross-collaboration in growing a extra full response to urgent world vitamin challenges, comparable to entry to nutritious and inexpensive meals, vitamin schooling, and sustainable meals techniques.
Its information and visualizations can be utilized to design tailor-made, evidence-based interventions and inform coverage adjustments or useful resource distribution. In the end, these mixed efforts at particular person, neighborhood, and coverage ranges can have a constructive ripple impact on the vitamin and well being statuses of individuals all through the world, says Naumova.
Tufts Now spoke with Naumova to be taught extra concerning the Atlas’s genesis, gaps in information, and the database’s function in future vitamin analysis.
Tufts Now: What prompted the creation of the World Vitamin and Well being Atlas?
Elena Naumova: We wished the GNHA to be each a instrument of analysis and public service empowerment. Huge information units can be found on-line, nonetheless, they are often laborious to search out or obscure. To deal with these challenges, we created one location that incorporates pertinent well being information and permits for it to be offered in a visually fascinating method.
The location is a repository for over 1,000 metrics belonging to 6 dimensions: demographics, dietary consumption, dietary standing, well being standing, well being economics, and meals sustainability. The info included is wide-ranging, extremely detailed, validated, and publicly obtainable. Not solely is it vital to supply prime quality information, but in addition to present instruments for correct evaluation and utility.
To empower the general public, the platform presents coaching and case research for information utilization. Our hope is that by selling information entry and coaching, there’s larger room for cross-collaboration and modern interdisciplinary analysis alternatives amongst a wide range of customers.
Gathering this information in a single place might help us overcome a few of the challenges in making knowledgeable suggestions for wholesome diets and vitamin. When researchers and policymakers have entry to a fuller image of dietary patterns, gaps in nutrient consumption, environmental affect, consuming habits and dietary necessities for youngsters and infants, and the variety of well being care amenities in a area, for instance, they’ve a greater concept of what and the place sources have to be deployed to advertise wholesome vitamin.
The place does the info come from?
Our focus is to attract information from respected sources which are examined by time and its customers. The GNHA curates information from greater than 15 public databases, such because the World Financial institution, World Well being Group, United Nations, and Dietary Family Survey, and inner sources like Nestlé, the World Dietary Database, and the World Burden of Illness.
The info might be accessed both as collective metadata or by particular indicators, timespan, and nation/ area of curiosity. As a world database, this can be a place to acquire vitamin and well being info, in addition to deposit your individual information.
Lacking information is an issue that sometimes accompanies massive information units. How does the Atlas confront this problem?
Lacking information is a major problem regardless of how massive the info set. As a result of it is a frequent problem, we’re dedicated to transparency and information high quality assurance. Knowledge solely comes from established and credible public sources, and it is reviewed previous to being added to the platform. All information is accompanied by well-documented metadata that incorporates info on how a lot of it’s lacking, a glossary of phrases and their definitions, and hyperlinks to the unique supply.
We additionally should remember the fact that sometimes with massive, world information units, some voices get misplaced within the dialog. In some nations, information assortment is difficult due to useful resource limitations, price, and upkeep issues. If lacking information can’t be addressed, it is important at a minimal to boost consciousness concerning the problem and preserve transparency and parity.
How do you envision this instrument enhancing vitamin analysis and, probably, a few of the six dimensions tracked within the GHNA, comparable to dietary standing or meals sustainability?
Knowledge from the GNHA can consider in addition to evaluate indicators at nation, area, and world ranges, both to one another or over time. Finding out these relationships can inform us as researchers what indicators have improved and the place future interventions might have to be focused.
A serious element of enhancing vitamin analysis is schooling, and the platform’s academic advantages are two-fold. First, it presents the following wave of researchers, college students, and policymakers a chance to be taught from information visualization. Graphic or pictorial representations can simplify complicated information units and convey info in a fast, environment friendly method. That may immediate stronger and more practical interdisciplinary approaches to time-sensitive issues comparable to malnutrition, diet-related illnesses, and maternal well being.
Furthermore, visualizations can reveal patterns or developments that in any other case could not be captured. Many people are visible learners and seeing information via a colourful show could make it extra understandable. From a coverage and intervention perspective, it permits for understanding of what researchers and policymakers have been doing proper, and the place we have to enhance.
As researchers, we’re hopeful that future tasks and interventions will use the GNHA. We additionally welcome and look ahead to others’ contributions. As a dynamic information repository, the platform continues to hunt new information inside its present dimensions and collect info for brand spanking new disciplines which can be built-in.
