Analytical Investigation
Epi Information™ software, variation step 3.5.cuatro (2008), was utilized to procedure the details from the step 3-time food information. The food composition databases combined with which unit include step 1,655 items on after the supplies: step 1,307 foods on the Us Service of Agriculture, 80 delicacies on dinner composition tables of one’s Institute of Nutrients to possess Central America and Panama (INCAP), 254 delicacies out-of recipes commonly taken in Costa Rica, and you may thirteen meals in the Costa Rican compulsory fortification dining classification.
When you look at the diet intake analysis, outliers can be the consequence of misreporting or programming problems, or they might echo exact care about-statement from non-normative restaurants consumption. Outliers may possibly not be associate of your own population’s typical consumption shipping and can expose biases and you will negatively feeling mathematical research and you may inferences. We utilized sex-particular unweighted total times consumption in the first percentile otherwise significantly more than the new 99th percentile while the thresholds to own outliers, while the demanded from the Dyer mais aussi al. (59). This means that, 804 users remained throughout the last study.
Mean consumption try adjusted to own overall times intake utilizing the residuals means within the a beneficial regression model to your nourishment while the centered variable and effort because the independent varying (60). Though all of the mineral residuals presented normality otherwise near normality whenever plotted, particular distributions was skewed. These investigation didn’t hold way more directly on the typical shipments from the log transformation, therefore we decided to perhaps not journal changes the knowledge. To search for the differences between the entire properties of analytical attempt investigation, Chi-square was applied having categorical details and you may Student’s t-attempt getting proceeded variables.
Correlation anywhere between day-after-day nutrient intake regarding members and you will TCRAD results had been calculated. Mathematical benefit is actually determined out of Spearman’s Rating Buy relationship. Time modified median opinions of diet plan top quality rating areas was indeed compared across the around three TCRAD results. Pairwise numerous assessment data is actually conducted and you can mathematical relevance are computed regarding the standard Wilcoxon figure. To identify factors associated with the TCRAD get, i tested connections amongst the results and you may sex, decades, SES, college type of (public/private), and you may domestic urban area (rural/urban) having fun with a non-parametric ANOVA shot (Kruskal Wallis). SAS type nine.cuatro (SAS Institute) was applied for everybody analyses. Most of the screening have been dos-tailed while the analytical significance peak are set just like the 0.05.
Performance
Average consumption of time-modified 14 parts of brand new TCRAD get across the CRHEI categories are revealed inside Desk dos . For all half dozen fit components (kidney beans, make, good fresh fruit, veggie oil, milk, and you can tortilla), energy-adjusted median intakes were notably lower having adolescents which have lowest TCRAD get as compared to teenagers with moderate or high TCRAD get. With the eight unhealthy areas (purple meats, good oils, sweets, sugary beverages, snacks, fully processed foods, and dough application), energy-adjusted median consumption have been somewhat straight down to possess teens with high TCRAD rating vs. reasonable conventional rating. not, whenever you are sensed an unhealthy food and you will inversely obtained, median intake from white grain are significantly high when you look at the teenage with large TCRAD get versus. lower traditional score.
Dining table 2
Median (min-max) of your time-adjusted elements consumption of full and also by categories of the fresh Old-fashioned Costa Rican Adolescents Diet (TCRAD) rating (letter = 804) step one .
1 Consumption modified getting energy. 2 Diet plan top quality categories influenced by interquartile diversity values off score shipping. step three P-philosophy created getbride.org hier schauen by Wilcoxon analyses comparing median values between diet plan high quality categories. Pairwise contrasting advantages ( a decreased get TCRAD diet plan-Mediocre TCRAD, b High score TCRAD, c Average TCRAD), ‡significant all over most of the pairwise contrasting.
Overall, this new TCRAD get is actually notably correlated with all of checked nutrition but total energy, glucose, cholesterol, and you will calcium ( Table step 3 ). Overall weight, mono-, poly-, and saturated fats was indeed inversely and you may weakly coordinated into TCRAD rating. Soluble fiber, folate, magnesium, and you will potassium showed modest positive relationship toward TCRAD score.
