A Qualitative Study of Child Nutrition and Oral Health in El Salvador

The influence of parents' oral health literacy and behavior on oral health of preschool children aged 3-6 years- evidence from China

BACKGROUND

Direct and indirect associations have been identified among health literacy, health behavior, and health status. Thus, we aimed to investigate the influence of oral health literacy and behaviors in parents on their children's oral health status. Moreover, we aimed to analyze the mentioned mediating effects through oral health behavior management.

METHODS

Oral health information of 1,102 preschool children aged 3 to 6 years was collected from five primary schools in Jinjiang District, Chengdu City, Sichuan Province, China. The decay-missing-filled teeth (DMFT) index and soft scale plaque index (PI) were used by professional dentists aided by school teachers to assess caries and periodontal health among the children. Simultaneously, we conducted a questionnaire-based survey among the parents to determine their oral health literacy and health behavior and their children's oral health behavior. The probit model, instrumental variables, and mediation effect model were used to evaluate the association of parents' oral health literacy and behavior with their children's oral health status.

RESULTS

The DFMT index was 1.58 among the children, with zero caries in 646 (58.6%) children. The PI was 0.68, with zero gum disease in 517 (46.9%). The univariate analysis suggested that the parents' health literacy and behavior were correlated with their children's oral health status (P < 0.01). Parents' oral health behavior significantly affected their children's oral health status. Simultaneously, a stronger correlation was observed upon using parents' health literacy as an instrumental variable to assess the endogeneity, indicating endogeneity problems. Parents' health-related behaviors exerted a mediating effect on children's oral health, with parents helping children brush their teeth demonstrating the strongest effect.

CONCLUSION

Parents' oral health-related behaviors can affect their children's oral health status. We recommend enhancing parents' oral health literacy to improve children's oral health status.

Caries indicators in relation to healthcare access and hygienic-dietary habits in Spanish preschoolers

INTRODUCTION

Dental caries continues to be a public healthcare problem due to its high prevalence and morbidity. It was proposed to evaluate caries indicators in relation to healthcare access and hygienic-dietary habits in Spanish preschoolers.

MATERIALS AND METHODS

A cross-sectional study was carried out on a random sample consisting of 343 patients ranging from 3 to 5 years of age in the primary care setting, the main measurements were: dental care access, hygienic-dietary habits, and caries registration according to WHO criteria.

RESULTS

The prevalence of caries was 35.3% and mean ± standard deviation (SD) dft was 1.51 ± 2.93. Preschoolers who had ever visited the dentist had a higher dft occurrence than those who had never attended the dentist. The lower prevalence of caries was significantly associated with the frequency of two daily brushings versus non-daily brushing (p = 0.007; 25.3% vs. 47.1%) and was 10.7% lower in patients who had the habit of night brushing (p = 0.041). The consumption of sugary liquids between meals implied a higher dft index.

CONCLUSIONS

The high prevalence of early childhood caries and the dental care access associated with poor oral health suggest the need to implement a multidisciplinary oral healthcare program that involves both healthcare and dental healthcare professionals in Primary Health Care Units without forgetting the participation of the community and local administrations.

Association between body weight misperception and snacking patterns among adolescents: a population-based cross-sectional study

BACKGROUND

Unhealthy snacking behaviors and body weight misperception are both significant concerns in adolescent health. Weight misperception are common among youth and may influence their motivation to engage in health-related behaviors, however, the effect on snacking patterns choice remains unclear. Our study aimed to examine the relationship between body weight misperception and snacking pattern choice among school adolescents.

METHODS

A cross-sectional study was conducted using an online survey platform. Body weight misperception was defined based on perceived body weight and true weight. Snack intake was measured using a qualitative food-frequency questionnaire. Factor analysis was used to identify snacking patterns, and multiple linear regression was employed to examine the association between body weight misperception and snacking patterns.

RESULTS

190,296 students with the average age of 13.3 ± 1.0 years was included, and 44.5% of students misperceived their weight. Overestimation was more prevalent than underestimation. Two snacking patterns, namely a high-calorie snacking pattern and a healthy snacking pattern, were identified with eigenvalues > 1. Weight underestimation was positively linked to high-calorie snacking pattern scores for both normal weight students (β: 0.16, 95% CI: 0.11, 0.21) and students with overweight/obesity (β: 0.44, 95% CI: 0.35, 0.52), and to healthy snacking scores for students with overweight/obesity (β: 0.28, 95% CI: 0.22, 0.33), but negatively linked to healthy snacking pattern scores for normal weight students (β: -0.12, 95% CI: -0.15, -0.09). Conversely, weight overestimation was negatively linked to both high-calorie and healthy snacking pattern scores for normal weight students (β: -0.07, 95% CI: -0.11, -0.04 and β: -0.13, 95% CI: -0.15, -0.10), but positively linked to healthy snacking scores for underweight students (β: 0.15, 95% CI: 0.08, 0.21). Interactions were found between sex, grade, accommodation, only child, primary guardians, parental education level and weight misperception to snacking patterns.

CONCLUSIONS

Adolescents with normal weight and overweight/obesity who misperceived their weight exhibited less healthy snacking patterns, whereas underweight students who misperceived their weight displayed healthier snacking patterns. Comprehensive programs are crucial to educate and guide adolescents in understanding their weight status and making healthier snack choices, involving families, schools, and society.

User requirement gathering for online oral health education module development: Exploring parental perspective

Objective

Dental caries is preventable, yet it remains a common childhood disease. As children are dependent on their parents for oral health care, oral health education for parents is essential to ensure they understand the risk factors and consequences of dental caries and their role in its prevention. This study aims to explore parents' oral health education needs to enable the development and provision of a tailored online oral health education module.

Methods

Online focus group discussions were conducted among Malaysian parents to gather information about the content, layout and presentation of oral health information parents sought for the provision of oral health care for their children. Video recordings were transcribed verbatim and thematic analysis was performed using an inductive approach.

Results

In total, 24 parents participated in the discussions and 4 main themes were uncovered. The first theme was perceived information needs related to dental caries, oral health care and the importance of deciduous teeth. The second theme was parents' preferred information resources which were social media, dentists, mobile phone applications and medical personnel. Thirdly, information delivery format and specific characteristics were recommended. The final theme was challenges and barriers faced in maintaining oral health due to parental constraints, child behaviour and external factors.

Conclusion

Parents' profound feedback and experiential standpoint stipulate the need for the development and delivery of a comprehensible and visually engaging oral health education module by healthcare professionals via social media to enable access to evidence-based information consistently.

Healthy Food, Healthy Teeth: A Formative Study to Assess Knowledge of Foods for Oral Health in Children and Adults

Eating patterns characterised by low intakes of processed carbohydrates and higher intakes of fat- and Vitamin D-rich foods are associated with protection against dental caries. The aim of this formative study was to evaluate the extent to which the knowledge of children and adults of foods for oral health reflects dietary guideline advice, and the evidence base for foods associated with increased and decreased caries burdens. Using a novel card-sorting task, the participants categorised foods according to their knowledge of each food for oral health. There were no differences between children and adults in the categorisation of fresh, minimally processed foods. Fish, chicken, and red meat were categorised as healthy by significantly fewer children than adults. High-sugar foods were correctly characterised as unhealthy by nearly all participants. More children categorised breakfast cereals as healthy than adults. There were no statistically significant differences between children and adults for the categorisation of brown or wholegrain breads categorised as healthy. The alignment of the participants’ beliefs with dietary guideline recommendations suggests education through health promotion initiatives is successful in achieving knowledge acquisition in children and adults. However, recommendations to increase the intake of refined carbohydrates inadvertently advocate foods associated with increased caries burdens.

Sugary Liquids in the Baby Bottle: Risk for Child Undernutrition and Severe Tooth Decay in Rural El Salvador

As communities worldwide shift from consuming traditional diets to more processed snacks and sugar-sweetened beverages (SSBs), increases in child obesity and tooth decay and persistence of undernutrition are particularly apparent in Latin American countries. Further evidence of shared risk factors between child undernutrition and poor oral health outcomes is needed to structure more effective health interventions for children’s nutrition. This study aims to identify dietary, oral health, and sociodemographic risk factors for child undernutrition and severe early childhood caries (sECC) among a convenience sample of 797 caregiver–child pairs from rural Salvadoran communities. Caregiver interviews on child dietary and oral health practices were conducted, and their children’s height, weight, and dental exam data were collected. Multivariable regression analyses were performed using RStudio (version 1.0.143). Caregiver use of SSBs in the baby bottle was identified as a common significant risk factor for child undernutrition (p = 0.011) and sECC (p = 0.047). Early childhood caries (p = 0.023) was also a risk factor for developing undernutrition. Future maternal–child health and nutrition programs should coordinate with oral health interventions to discourage feeding children SSBs in the baby bottle and to advocate for policies limiting SSB marketing to young children and their families.
