Describe and evaluate current prevalence of nutrition-related chronic health outcomes.
Approach to Answering the Question
Data Analysis and Food Pattern Modeling Cross-Cutting Working Group
Data Analysis Protocol
Developed for each scientific question being examined, the protocol describes the plan for how the data analysis will be conducted. The protocol provides the:
- Analytic framework,
- Analytic plan, and
- Analysis results.
For this question, the prevalence of nutrition-related chronic health conditions are outcomes consistent with nutrition-related chronic health conditions being examined as part of the systematic review approach. These will be described using nationally representative data descriptive of the U.S. population.
The following categories of nutrition-related chronic health conditions will be considered:
- Growth, Size and Body Composition Outcomes
- Food Allergy Disease Outcomes
- Cardiovascular Intermediate and Endpoint Outcomes
- Cancer Outcomes
- Type 2 Diabetes
- Metabolic Syndrome
- Chronic Liver Disease
- Gestational Diabetes
- Pregnancy-related Hypertensive Disorders
Draft Conclusion Statement
The draft conclusion statements listed below describe the state of the science related to the specific question examined. Draft conclusions are not considered final until they have been deliberated with and decided upon by the full Committee and published in the Committee’s final advisory report. Individual conclusion statements should not be interpreted as dietary guidance or the Committee’s overarching advice to the Departments.
Nutrition-related chronic health conditions are common across every life stage of the U.S. population; those related to unhealthy diet, overweight, and obesity remain highly prevalent among all age groups. There are disparities in the severity of the prevalence, incidence, or mortality rate of chronic health conditions between groups classified by sex, age, race-ethnicity, income level, and weight status. In general, chronic health conditions have become more prevalent over time and are highest among older populations, racial and ethnic minority groups, and those with lower income levels.
