Oral health behaviours and cariogenic food consumption in children with attention-deficit/hyperactivity disorder: a cross-sectional study.

Background: Attention-deficit/hyperactivity disorder (ADHD) contributes to functional impairments in the performance of personal tasks such as oral hygiene. This study aimed to compare oral health behaviours and consumption of cariogenic foods in children diagnosed with ADHD and healthy control peers. Methods: In this cross-sectional study, 60 children with ADHD aged 6 to 11 years made up the study group, and 60 peers of the same age, sex, and from the same school, without a history of ADHD, made up the control group. To compare the parent-reported behaviours between the 2 groups, conditional logistic regression was used to obtain matched pairs odds ratios (ORs) and 95% confidence intervals (CIs). Results: Children with ADHD were 0.4 times less likely than their non-ADHD peers to brush their teeth at least once a day (OR = 0.40, 95% CI: 0.18-0.91, p = 0.028). Moreover, compared to the control group, children with ADHD were 4.71 and 9.67 times more likely to consume cariogenic foods (95% CI: 2.08-10.66, p < 0.001) and drinks (95% CI: 2.94-31.73, p < 0.001), respectively, at least thrice a day. Conclusion: In comparison to their non-ADHD peers, children diagnosed with ADHD were less likely to brush their teeth and simultaneously more likely to consume both cariogenic foods and drinks.

Introduction: Le trouble déficitaire de l'attention avec hyperactivité (TDAH) contribue aux déficiences fonctionnelles dans l'exécution de tâches personnelles comme l'hygiène buccale. Cette étude visait à comparer les comportements en matière de santé buccodentaire et la consommation d'aliments cariogènes chez les enfants ayant reçu un diagnostic de TDAH et chez des enfants témoins en bonne santé. Méthodes: Dans cette étude transversale, 60 enfants ayant un TDAH, âgés de 6 à 11 ans formaient le groupe d'étude, et 60 enfants du même âge, du même sexe et de la même école, sans antécédents de TDAH, formaient le groupe témoin. Pour comparer les comportements déclarés par les parents entre les 2 groupes, on a utilisé des modèles de régression logistique conditionnelle pour calculer le rapport des cotes (RC) par paires appariées avec des intervalles de confiance (IC) de 95 %. Résultats: Les enfants atteints de TDAH étaient 0,4 fois moins susceptibles que leurs pairs sans TDAH de se brosser les dents au moins une fois par jour (RC = 0,40, IC à 95 % : 0,18 à 0,91, p = 0,028). De plus, comparativement au groupe témoin, les enfants atteints de TDAH étaient 4,71 et 9,67 fois plus susceptibles de consommer des aliments (IC à 95 % : 2,08 à 10,66, p < 0,001) et des boissons cariogènes (IC à 95 % : 2,94 à 31,73, p < 0,001), respectivement, au moins trois fois par jour. Conclusion: Comparativement à leurs pairs sans TDAH, les enfants souffrant de TDAH étaient moins susceptibles de se brosser les dents et simultanément plus susceptibles de consommer à la fois des aliments et des boissons cariogènes.

The effect of training intervention based on the theory of planned behavior on oral and dental health behaviors in pregnant women.

BACKGROUND: Pregnancy is a transient physiological condition that causes adverse oral and dental consequences. The present study aimed to determine the effect of a training intervention based on the theory of planned behavior on oral and dental behaviors in pregnant women. METHODS: This quasi-experimental study was conducted on 140 pregnant women (70 in the intervention group and 70 in the control group) supported by comprehensive health centers on the outskirts of Shiraz, Iran, in 2019-2020. The sampling was performed in each center by a simple random method. The tool included a demographic characteristics questionnaire, a questionnaire based on the theory of planned behavior, a self-care behavior questionnaire, and checklists for recording DMFT(Decayed, Missing due to caries, and Filled Teeth(DMFT)) and dental plaque indices. The questionnaires were completed before and 3 months after the intervention by both groups. The intervention group received six 50-min training sessions. The data were analyzed using SPSS 22, the chi-squared test, independent t-test, paired t-test, and descriptive statistics (p < 0.05). RESULTS: The mean ages of the intervention and control groups were 32.28 ± 6.14 and 31.84 ± 6.71, respectively. The results showed that the average scores of all constructs of the theory of planned behavior, dental plaque indices (PI), and MDFT in the intervention group significantly changed after the intervention (p < 0.001). CONCLUSION: According to the results, training based on the theory of planned behavior was effective on dental and oral health behaviors in pregnant women and improved the clinical results of their self-care behaviors. Therefore, training sessions will increase the knowledge of pregnant women, and providing timely consultations and examinations can be helpful and effective in developing oral and dental health behaviors in pregnant women.

Effect of training based on health belief model and behavioral intention on improving dental and oral self-care behavior in 9-12-year-old Iranian female students.

BACKGROUND: Training dental and oral health behaviors by using appropriate training models and theories is an important issue in preventing dental and oral diseases. the present study aimed to investigate the effect of training based on the health belief model and behavioral intention on dental and oral health behaviors in female students aged 9-12 years old in the city of Rudsar, Guilan, Iran. METHODS: This research is an interventional study conducted on 84 female students aged 9-12 years old, who lived in the city of Rudsar (n = 42 in the control group and n = 42 in the interventional group) in 2019. The data collection tools included questions on demographic variables, structures of the health belief model (perceived sensitivity, perceived severity, perceived barriers and benefits, self-efficiency), behavioral intention, and performance. The questionnaire was completed before the intervention and 3 months after it by both groups. The intervention group received four 45-min sessions. The data were analyzed using SPSS 24, descriptive tests, independent sample t-test, pair sample t-test, and regression (P < 0.05). RESULTS: The mean age of the intervention and control groups was 10.88 ± 1.01 and 10.80 ± 1.01, respectively. The results showed that the average scores of all structures of the health belief model and behavioral intention in the intervention group significantly changed compared to the average scores obtained before the intervention (P < 0.05). Moreover, the average scores of perceived sensitivity (p < 0.009), perceived barriers (p < 0.007), self-efficiency (p < 0.001), and behavioral intention (p < 0.001) significantly changed after the intervention in both groups (p < 0.05). CONCLUSION: According to the results, the health belief model and the behavioral intention were effective in improving dental and oral health so that they can be applied to improving people's dental and oral health. It can also be used as a model to design, implement, and monitor medical health programs.

Optimal Solution of a Fractional HIV/AIDS Epidemic Mathematical Model.

This article presents a fractional mathematical model of the human immunodeficiency virus (HIV)/AIDS spread with a fractional derivative of the Caputo type. The model includes five compartments corresponding to the variables describing the susceptible patients, HIV-infected patients, people with AIDS but not receiving antiretroviral treatment, patients being treated, and individuals who are immune to HIV infection by sexual contact. Moreover, it is assumed that the total population is constant. We construct an optimization technique supported by a class of basis functions, consisting of the generalized shifted Jacobi polynomials (GSJPs). The solution of the fractional HIV/AIDS epidemic model is approximated by means of GSJPs with coefficients and parameters in the matrix form. After calculating and combining the operational matrices with the Lagrange multipliers, we obtain the optimization method. The theorems on the existence, unique, and convergence results of the method are proved. Several illustrative examples show the performance of the proposed method.

Dimensional Structure of the Early Childhood Oral Health Impact Scale.

Background: Detecting the latent dimensions of quality of life as affected by oral diseases is essential for promoting oral health in children. This study aimed to test the Early Childhood Oral Health Impact Scale (ECOHIS) via an appropriate method to detect its dimensions of quality of life as affected by oral diseases. Methods: An analytical cross-sectional study was carried out in Shiraz, Iran, between 2014 and 2015. A multistage stratified design was used to select 830 parents or the guardians of primary school children aged six years. The Farsi version of the Early Childhood Oral Health Impact Scale (F-ECOHIS) was used to evaluate the children's oral health-related quality of life. The parents were interviewed to collect data on ECOHIS. Mplus, version 7, was employed for descriptive and analytical analyses in the present study. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to extract and verify the latent dimensions of ECOHIS. Results: Out of the 830 invited parents or guardians, 801 participated in this study. The mean ECOHIS score was 21.95±7.45. The mean child impact score and the mean family impact score were 14.25±5.72 and 7.70±3.62, respectively. EFA yielded a 3-factor model: symptom and function, social interaction, and family impact. CFA confirmed the 3-dimensional model (root mean square error of approximation=0.045). The fit indices of the 1- and 2-dimensional models (the child and family domains) were not within the acceptable range. Conclusion: F-ECOHIS is a 3-dimensional model rather than the hypothetical 6-dimensional model. ECOHIS appears to be a useful scale for measuring the multidimensional impact of oral diseases in children.

The effect of training interventions on the psychological factors of oral health in pregnant women.

BACKGROUND AND AIM: Oral health is crucial for high-risk pregnant women in order to preserve their health and the health of their infants. Therefore, this study aimed to determine the impact of training programs on the behavior of pregnant mothers concerning oral health in Khorramabad, Iran. METHODS: This is an educational experimental study carried out in 2015 on 164 pregnant women referring to health centers in the city of Khorramabad who were randomly divided into two groups (each n=82). The instruments for data collection included a questionnaire based on the Health Belief Model regarding oral health and two checklists of oral health indexes (OHIS and DMFT). Data were analyzed using SPSS 20 via paired-samples t-test, independent-samples t-test and Chi-square. RESULTS: The mean score of knowledge and performance, and the variables of the components of the Health Belief Model including the perceived susceptibility, severity, benefits, barriers and self-efficacy regarding the oral health care, significantly increased in the intervention group following the training intervention (p<0.001). However, the DMFT index did not show any changes after the intervention in the intervention and control groups (p=0.381). On the other hand, the OHIS index significantly decreased in the intervention group as compared with the pre-intervention scores (p=0.002). CONCLUSION: The results of this study showed that training based on the Health Belief Model leads to the enhancement of performance regarding oral health in pregnant women and thus prevents any increase in OHIS and DMFT levels during pregnancy.

Association of Oral Health Indicators with Quality-of-Life Related to Oral Health among Iranian Adolescent.

BACKGROUND: There has been an increase in the development and use of oral health-related quality-of-life (OHRQoL) measures in the past two decades. This study aimed to assess the association between OHRQoL and clinical oral health measures, among mid-level school children in Southeast of Iran. MATERIALS AND METHODS: A cross-sectional study was conducted on a random cluster sample of 11-13 year-old student population. Consented participants interviewed for OHRQoL measurements using Persian version of child-oral impacts on daily performances (OIDP). Oral examination was done by a trained dentist using WHO oral health assessment form, version 2011. Data were analyzed by SPSS software version 20 using Mann-Whitney and correlation tests. RESULTS: A total of 400 school children participated. The overall mean of decayed missing filled teeth (DMFT) was 1.76 ± 2.4. A total of 82% of the school children presented the impact of oral problems in at least one of the eight daily performances. As DMFT increased, the OIDP score tended to increase or quality-of-life of children tended to be worse (r = 0.397, P < 0.001). CONCLUSIONS: The results showed a positive relation between some oral health status and quality-of-life score.
