Other covariates sensed incorporated every day supplement D and you may multivitamin complement play with, annual dental office check out (annual or otherwise not), tooth-brushing regularity (twice a day or not), flossing frequency, ages and you will sex.

Data were accessed and analyzed at the Research Data Centre (RDC) at the University of Manitoba using SPSS 20 (IBM, Armonk, NY), SAS 9.2 (SAS, Cary, NC), and Stata 13 MP (StataCorp LP, College Station, Tex.). As per RDC restrictions, original sample sizes were suppressed. Bootstrap weights for variance estimation and weighted results are presented with degrees of freedom fixed to 11. Descriptive statistics include means and frequencies with 95% confidence intervals (CI). ? 2 tests were used to determine the unadjusted correlation of each categorical independent variable with GI and LOA. Student t tests were used to determine the unadjusted correlation of each continuous independent variable with GI and LOA. Three multiple logistic regression models for GI and for LOA were developed to determine the adjusted association between 25(OH)D levels and GI and LOA, controlling for potential confounders. Model A used 25(OH)D concentration of < 50 nmol/L, model B used 25(OH)D concentration < 75 nmol/L, and model C used mean 25(OH)D concentration. Variables with a p value of ? 0.075 were included in the multiple logistic regression analysis for GI and LOA, with the exception of plasma vitamin D concentration and known risk factors for periodontal disease, such as smoking. A p value ? 0.05 was significant.

Overall performance

The mean 25(OH)D concentrations (95% CI) in the GI and LOA samples were 90.8 (77.5–104.2) and 85.6 (74.6–97.2) nmol/L, respectively. Although mean 25(OH)D levels were above the thresholds for vitamin D sufficiency, 63% of each sample had concentrations below the 75 nmol/L threshold and 25% of each population had 25(OH)D levels < 50 nmol/L.

But not, when confounding details was indeed managed to have, several logistic regression studies out of GI (Table 2) indicated that just plaque and you will gender was significantly associated with the GI

Bivariate analysis of GI (Table 1) [Ed. Note: All Tables in this article are available in the PDF version]. showed that several variables were significantly associated with 25(OH)D concentrations below the thresholds for vitamin D sufficiency. Participants with 25(OH)D concentrations < 50 nmol/L and < 75 nmol/L had significantly increased odds of having more GI (odds ratio (OR) 1.63 and 1.44, respectively). Those taking vitamin D supplements had significantly lower odds for GI (OR 0.56), while those with diabetes had increased odds of having moderate to severe GI (OR 1.33). Mean BMI was significantly higher among those with the worst GI. Meanwhile, those who reported frequenting a dental professional ? 1 time a year, brushing their teeth twice daily and flossing daily had significantly lower odds for GI. Increased scores for plaque were associated with increased odds for moderate to severe GI. Males had increased odds for GI compared with females, while those in higher-income categories had lower odds for GI than those in lower-income categories.

Women got straight down odds of reasonable so you can major GI, when you’re large beliefs to your plaque index enhanced chances from modest to big GI. Zero tall relation anywhere between 25(OH)D and you may GI is actually present in models A beneficial, B otherwise C from the numerous logistic regression data from GI.

Multiple variables was tall about bivariate study regarding LOA (Table step three). Contrary to popular belief, delivering an excellent multivitamin or a vitamin D complement is of the increased probability of more serious LOA. High indicate HbA1c beliefs had been with the improved likelihood of alot more major LOA because the is HbA1c > https://datingranking.net/escort-directory/dayton/ 7%. Old age try of the enhanced odds of more serious LOA, while you are an income of > $sixty 000 is actually of this straight down probability of more serious LOA. Zero significant organization try discover anywhere between twenty five(OH)D profile and you can LOA on bivariate research.
