Overview

The WHO/Cochrane/Cornell University Joan Klein Jacobs Center for Precision Nutrition and Health Summer Institute offers a combination of online and in-person learning. We bring together experts from the World Health Organization (WHO), Cochrane and Cornell to train participants in the development of systematic reviews of nutrition interventions in populations. We have excellent outcomes, and participants have contributed to producing reviews that inform global guidelines. 

The format includes one week of online instruction, which is primarily self-directed and tailored by each person to fit their schedule. This is followed by a second week of residential, in-person training. The online preparation brings all participants to a common starting point, which prepares us to maximize training during the in-person week on the Cornell University campus in Ithaca, New York

2025 Dates

Week 1: Cochrane Methods for Systematic Reviews of Interventions

May 19-25, 2025
Asynchronous online training

In early May, we will provide access to all materials so participants can start with online materials as early as their schedule allows. Week 1 is asynchronous online training; work at your own pace and on your schedule. During this online week, we expect you to reserve about four hours per day to work through modules on basic concepts in systematic reviews. Week 1 will also include three online interactive sessions (1 hour each time), which will be recorded to accommodate time zone differences. 

Prior to the first week, we will make introductions among participants and faculty, including forming teams and working on logistics to facilitate the goals of the institute.

Week 2: Immersive training in Systematic Reviews and Global Policy Making

June 15-20, 2025
In-person training, Cornell University, Ithaca, New York

During week 2, we will convene in person for a residential week on the Cornell campus. Here, you will be fully immersed in training, discussions, networking and learning from our expert faculty and each other.

Outcomes

Systematic reviews following the Cochrane methodology are used by the WHO and ensure that WHO recommendations are based on sound evidence. You will learn Cochrane methods, including applying the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool to assess the overall certainty of evidence.

Questions? Contact summerinstitute [at] cornell.edu (SummerInstitute[at]cornell[dot]edu).

Once you are accepted to the institute, you will receive notification and further details about registration in March. We will require you to register for the program, including completing payment. Your acceptance letter will provide detailed instructions. 

Briefly, the registration steps are: 

  1. Complete the registration process through Cornell Conference Services using the link provided in your acceptance letter.
  2. Be ready to provide payment at the time of registration. Direct payment questions to: summerinstitute [at] cornell.edu (SummerInstitute[at]cornell[dot]edu)
  3. Complete a short biography for the directory and register for a Cornell University NetID following the directions in your acceptance letter.
  4. On or about May 1, you will be invited to complete one pre-institute information session to learn how to access materials, discuss review topics and hear more about the plan for working in groups.
  5. Once systematic review groups are assigned, you are encouraged to meet at least once before the program starts to form connections and discuss the systematic review status.

Registration fees

The $2,000 registration fee covers the following: 

  • advance preparation materials
  • materials used in first week of Institute (asynchronous content)
  • all course instruction
  • access to Cornell’s library resources
  • access to Cornell’s Statistical Consulting Unit advisors
  • access to the institute’s virtual platform
  • two coffee breaks per day, the welcome tour, the opening reception and the institute dinner

As described below, participants from low- to middle-income countries (LMIC) and upper-middle-income countries (UMIC) will be considered for a scholarship only if they meet the delineated criteria (please review the criteria and be sure that you address these criteria in your cover letter). For participants who are directly affiliated with institute partners, further discounts will apply. You should indicate your affiliation in the application.

Estimating the cost of housing and meals

Housing and the majority of meals are not included in the registration fee, except for the events listed above. 

Housing is available in the Cornell townhouses located on the North Campus, approximately a 15-minute walk distance from our site. The housing cost for 2025 is $129.25 per night per single bed in a shared townhouse. Each townhouse has two bedrooms, a bathroom, a living/dining room and a kitchen. All townhouses are close to dining options on Cornell’s North Campus, specifically Morrison Hall, Cornell’s newest and highly acclaimed eating establishment offering a wide range of options. 

Participants are not required to stay in campus housing, but most participants opt for campus housing given its proximity to our institute meeting space, ease of arrangement and access to the dining facilities. You may instead choose from hotels or other housing options in Ithaca, but you must carefully consider transportation options to and from campus. 

Participants typically use campus dining facilities for meals, which are very economical at an approximate cost of $40/day to cover breakfast, lunch and dinner. The North Campus townhouse accommodations also have cooking facilities. 

Participants are responsible for their own transportation costs, including airline tickets, taxis or buses.

Scholarships

A very limited number of scholarships for participants from low- and middle-income countries are available to help cover registration, travel, accommodation and other expenses associated with participating in the institute.

Funds are limited, so you must also take responsibility to explore partial or full funding options from other sources, such as your institution or available grants.

Scholarship eligibility

We will consider individuals for a scholarship if they meet the following criteria, which should be addressed in your cover letter:

  • Permanent residents (living and working in) in low-, lower-middle- and upper-middle-income countries as defined by the World Bank.
  • Able to attend the entire Summer Institute 2025. Ensure that the dates do not conflict with any other commitment you may have and that your employer agrees to release time to allow you to attend the institute and to continue working on systematic reviews at some level after completing the program.

Partial funding

In an effort to fund as many people as possible to attend the institute, our preference will be to provide partial support only. Your chances of receiving a scholarship are higher if you demonstrate that you can cover part of the costs from other sources (for example, cover some of the following: travel, meals, registration or accommodation).

Persons temporarily based in high-income countries

Applications from residents of low- and middle-income countries who are currently based in a high-income country may be considered on a case-by-case basis if their stay is clearly limited to a specific period and the applicant does not receive a salary. 

Decision-making criteria

Applicants will be assessed according to the following criteria. Make sure to address them in your application.

  • Anticipated gains from attending the summer institute
  • Ability to raise partial funds to support attending
  • Letters of reference provided by people in your institution that address the relevance and the institutional value of your participation in the summer institute

What costs are covered?

Funds may be available for one or more of the following:

  • Travel to and from Ithaca, New York (at the level of the most economical return fare from your location)
  • Accommodation at Cornell in the townhouses during the in-person week
  • Summer institute registration fee

Depending on your country of citizenship, you may be required to have either a B-2 Tourist Visa or an Electronic Travel Authorization (eTA) to enter the United States.

Participants are responsible for covering all costs associated with obtaining a visa for the institute. This includes but is not limited to application fees, processing fees, travel to the consulate or embassy and any other expenses related to visa acquisition.

We do not provide financial assistance, reimbursements or sponsorship for visa-related costs. However, upon acceptance into the course, the acceptance letter from the institute provides the information you need in support of obtaining a visa, if a visa is required.

We recommend that you begin the visa application process as soon as possible to ensure timely processing. Contact your local consulate or embassy for more information regarding visa requirements.

We will combine online training (work at your own pace) with in-person sessions on the Cornell University campus. The formal program is two weeks in length, requiring consecutive days of availability May 19-25, 2025, for asynchronous online instruction and June 15-20, 2025, for synchronous meetings and work sessions in Ithaca, New York. You should plan to arrive in Ithaca on June 14 so you can to attend an opening social event during the day on June 15, and to depart Ithaca the afternoon of June 20 or on June 21.

Program topics

Through didactic sessions and hands-on exercises, you will learn the process of conducting and publishing a systematic review on nutrition interventions by participating in the development and publication of a systematic review. 

You will actively work on reviews to bring concepts to life through direct illustration and practice. Reviews produced by the participants have been published (both Cochrane and non-Cochrane) and used in WHO guidelines for member states. Topics vary from year to year, and participants are encouraged to bring forward reviews that they would like to work on with the team.

Topics change annually and vary depending on the interests of faculty mentors and participants. We encourage you to bring a review that you are working on, provided there is a willingness to collaborate. If you have a review you are working on, please make sure to tell us about it in your application materials. Past topics that led to published reviews:

  • Wheat flour fortification with iron for reducing anemia and improving iron status in whole and at-risk populations
  • Biofortified staple crops with increased micronutrient content for improving vitamin and mineral status in populations
  • Supplementation with iodine for women during pregnancy and lactation
  • Folic acid supplementation in children living in malaria-endemic areas
  • Growth monitoring and promotion (GMP) for children in low- and middle-income countries
  • Effects of oral vitamin D supplementation on linear growth and other health outcomes among children under five years of age
  • Caregiver involvement in interventions for improving children's dietary intake and physical activity behaviors
  • Effectiveness of provision of animal-source foods for supporting optimal growth and development in children 6 to 59 months of age
  • Health Facility Staff Training for Improving Breastfeeding Outcome: A Systematic Review for Step 2 of the Baby-Friendly Hospital Initiative
  • Healthy eating interventions delivered in early childhood education and care settings for improving the diet of children aged six years and below
  • Precision nutrition-based interventions for the management of obesity in children and adolescents up to the age of 19 years
  • Gut microbiome-based interventions for the management of obesity in children and adolescents up to the age of 19 years
     

Participants usually come to the institute with a review they wish to develop, a review they are working on, or as part of a team working on a review. A few participants will be assigned to topic areas based on their interests and availability. We will work on reviews in collaborative groups. Groups are led by internal mentors at the institute and/or by external mentors who are senior leaders on a review.
 

You will be required to complete preparatory work before the institute begins. This includes the online asynchronous week and the work on an actual review to collaborate with team members. You are strongly encouraged to work on a protocol or title registration prior to attending the program so that you can leverage the training to the fullest extent possible, and you will be expected to lead or co-lead the completion of the systematic review after completing the institute.

Participants will be provided with access to the Cornell University Library, the Cornell Statistical Consulting Unit and other facilities necessary to support the review work, and Cornell library access will continue post-institute for one year.

Typical session topics

Topics to be covered are delivered in a setting that provides opportunities for hands-on, small-group, interactive learning directly relevant to each review topic. 

  • RevMan introduction
  • RevMan advanced
  • GRADE introduction
  • GRADE advanced
  • PICO and development of the question, logic models
  • Protocol Development and Registration
  • Summary of Findings Table, Introduction
  • Summary of Findings Table, Advanced
  • Epidemiology methods: effect estimates and understanding risk of bias
  • Library: search strategies/implementation
  • Library: resources at Cornell University
  • Statistical methods: meta-analysis introduction, forest plot and heterogeneity
  • Statistical methods: random effects/fixed effects, cluster randomized studies and advanced meta-analysis
  • Statistical methods: resources at Cornell University
  • Non-randomized studies of interventions in Cochrane reviews

In the news

A Cochrane systematic review on the benefits and safety of fortifying wheat or maize flour with folic acid and population health outcomes, led by scientists in the Division of Nutritional Sciences at Cornell, found that fortification with folic acid (the synthetic form of folate) may improve folate status and reduce the occurrence of neural tube defects.
 

As a Cochrane Associate Center in the US Cochrane Network, the Division of Nutritional Sciences, Cornell University, furthered an ongoing collaboration with Cochrane and the World Health Organization to train nutrition scientists to produce systematic reviews in nutrition in support of global policymaking. 2024 marks the 10th year of the WHO/Cochrane/Cornell Summer Institute, and this collaboration has already produced reviews that contributed to global policies and guidelines. The goals of the Cochrane US Cornell University Center align closely with the Cochrane Nutrition Field and the new Cochrane Nutrition and Physical Activity Thematic Group, which seeks to promote evidence-informed decision-making on nutrition policy and practice. Cochrane reviews on nutrition and health, such as this recently published review on interventions to reduce the consumption of sugar-sweetened beverages, provide key evidence for policymaking; training nutrition scientists to conduct reviews is critical to develop and sustain worldwide capacity for this effort.
