Dietary patterns in Irish adolescents: a comparison of cluster and principal component analyses.
OBJECTIVE Pattern analysis of adolescent diets may provide an important basis for nutritional health promotion. The aims of the present study were to examine and compare dietary patterns in adolescents using cluster analysis and principal component analysis (PCA) and to examine the impact of the format of the dietary variables on the solutions. DESIGN Analysis was based on the Irish National ...
متن کاملComparison of cluster and principal component analysis techniques to derive dietary patterns in Irish adults.
The aims of the present study were to examine and compare dietary patterns in adults using cluster and factor analyses and to examine the format of the dietary variables on the pattern solutions (i.e. expressed as grams/day (g/d) of each food group or as the percentage contribution to total energy intake). Food intake data were derived from the North/South Ireland Food Consumption Survey 1997-9...

Genetic diversity is the basis of the natural evolution of plant breeding and biological system are important components of sustainability. The aim of this study was to evaluate 116 genotypes of Triticum turgidum from seven countries in terms of morphological traits. The results showed that high significant differences among the genotypes. The correlation between gra...

متن کاملA comparison of the dietary patterns derived by principal component analysis and cluster analysis in older Australians
BACKGROUND Despite increased use of dietary pattern methods in nutritional epidemiology, there have been few direct comparisons of methods. Older adults are a particularly understudied population in the dietary pattern literature. This study aimed to compare dietary patterns derived by principal component analysis (PCA) and cluster analysis (CA) in older adults and to examine their associations...
