Question(s)

Are prevailing patterns of diet behavior in a population, assessed using factor or cluster analysis, related to body weight or risk of obesity?

What is the relationship between adherence to dietary guidelines/recommendations or specific dietary patterns, assessed using reduced rank regression analysis, and measures of body weight or obesity?

Inclusion Criteria

Inclusion criteria for the dietary patterns systematic reviews included the following:

  • Human subjects
  • Subject populations from countries with high or very high human development, according to the Human Development Index[1]
  • Children, adolescents, and adults aged 2 years and older
  • Subjects who were healthy or at elevated chronic disease risk
  • Randomized or non-randomized controlled trial with at least 30 subjects per study arm and a follow-up rate of at least 80%, or a prospective cohort study
  • A description of the dietary pattern(s) consumed by subjects
In addition, articles were included if they were published in English in a peer-reviewed journal between January 1980 and August 2013 (see Appendices F-H for the date of the last search update for each question). If an author is included on more than one primary research article that is similar in content, the paper with the most pertinent data/endpoints was included. If data/endpoints from both papers are appropriate, it was made clear that results are from the same intervention.
 

Exclusion Criteria

Exclusion criteria for the dietary patterns systematic reviews included:

  • Animals and in vitro models
  • Subject populations from countries with medium or low human development, according to the Human Development Index
  • Children under the age of 2 years
  • Subjects who were hospitalized, diagnosed with disease, and/or receiving medical treatment
  • Low-calorie intervention (defined as <1, 600 kcal/day for women and <2, 000 kcal/day for men)
  • Systematic review, meta-analysis, narrative review, before and after, cross-sectional, or case-control designs
Articles were excluded if they were not published in English, or were published before January 1980. Articles, abstracts, and presentations not published in peer-reviewed journals (e.g., websites, magazine articles, Federal reports) were also excluded. Finally, if an author was included on more than one review article or primary research article that is similar in content, the paper with the most pertinent data/endpoints was included, and others were excluded.
