Associations between dietary diversity and self-rated health in a ... link.springer.com Springer Feb 28, 2025 5 facts

measurementA one-way ANOVA analysis found a statistically significant incremental increase in mean Dietary Diversity Score (DDS) as self-rated health (SRH) levels increased (p < 0.01).

procedureResearchers used a one-way ANOVA with post-hoc pairwise comparisons using Tukey’s test to compare mean Dietary Diversity Scores (DDS) across five categories of self-rated health (poor, passable, good, very good, and excellent).

procedureFor mean comparisons, the study used parametric univariate analysis of variance (ANOVA) and Student’s t-test when data met assumptions of normality (verified by residuals skewness, kurtosis, and Q-Q plots) and homoscedasticity (verified by Levene’s test), and used nonparametric Kruskal-Wallis tests with post-hoc Dunn’s test and Bonferroni adjustment when assumptions were not met.

measurementA two-way ANOVA revealed no statistically significant interactions between participants' regions of residence and self-rated health (SRH), regardless of whether SRH was dichotomized (p = 0.88) or not (p = 0.19).

measurementAn ANOVA analysis found statistically significant differences (p < 0.01) between mean Dietary Diversity Scores across the studied regions.
