Effects of nutrition and hygiene education on oral health and growth among toddlers in rural Uganda: follow-up of a cluster-randomised controlled trial

Every bite counts to achieve oral health: a scoping review on diet and oral health preventive practices

OBJECTIVE

To examine the landscape of preventive strategies and interventions directed to achieve oral health equity, with particular emphasis on the interplay between dental caries prevention, individual behaviors, and population-level strategies across various demographic and geographic regions.

METHODS

This scoping review was guided by Peters et al.'s framework, which incorporates four key concepts aimed at reducing caries: education for individuals and healthcare providers, behavioral modifications, addressing broader social determinants of health, and extending oral health education programs beyond traditional dental settings. A systematic search was conducted across five databases, from 2011 to 2022.

RESULTS

This review identified 107 studies highlighting three main themes: behavioral practices (N = 33), which focused on reducing the prevalence of caries, improving oral hygiene practices, and enhancing overall oral health knowledge; educational interventions (N = 39), which explored strategies to integrate oral health with broader public health initiatives; and dietary interventions (N = 35), which emphasized the critical relationship between diet and oral health.

CONCLUSION

This SR highlights the critical need for comprehensive multilevel approaches that address the complex interplay between nutrition, oral health, and sociodemographic factors, while emphasizing the critical relationship between societal factors and individual health behaviors. Multifaceted interventions that include behavioral change, education, and dietary modifications are crucial for improving oral and overall health outcomes across diverse populations. Comprehensive strategies should prioritize medical-dental integration and data-driven approaches to effectively reduce oral health disparities for vulnerable populations, promoting long-term health equity.

Knowledge, Attitudes, and Practices Associated with the Selection of Sweetened Ultra-Processed Foods and Their Importance in Oral Health

BACKGROUND

Reading nutritional labelling helps consumers select healthier food, thereby benefitting their oral health. The purpose of this study was to describe the knowledge, attitudes, and practices (KAPs) of parents and carers of children and preteens, associated with reading nutritional labelling, selecting sweetened ultra-processed foods, and their impact on oral health.

MATERIALS AND METHODS

This was a descriptive cross-sectional study in which a validated questionnaire was administered to 298 parents and caregivers of children aged 1-12 years from different districts in Villavicencio, Colombia. Participants' scores, based on the number of correct answers, were used to classify their level of KAP as low, medium, or high. In addition, the frequency of responses, the KAP levels, and the median scores were analysed. Finally, associations were determined using the chi-square test.

RESULTS

Most participants reached a medium level in terms of knowledge (41.6%) and attitudes (49.3%) and a low level in terms of practices (43.3%). An association was found between participants' level of KAPs and their socioeconomic and educational level (p < 0.05).

CONCLUSIONS

The study findings reveal inadequate KAPs associated with nutritional labelling, adequate food selection, and the importance of oral health.

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.

The role of national nutrition programs on stunting reduction in Rwanda using machine learning classifiers: a retrospective study

BACKGROUND

In Rwanda, the prevalence of childhood stunting has slightly decreased over the past five years, from 38% in 2015 to about 33% in 2020. It is evident whether Rwanda's multi-sectorial approach to reducing child stunting is consistent with the available scientific knowledge. The study was to examine the benefits of national nutrition programs on stunting reduction under two years in Rwanda using machine learning classifiers.

METHODS

Data from the Rwanda DHS 2015-2020, MEIS and LODA household survey were used. By evaluating the best method for predicting the stunting reduction status of children under two years old, the five machine learning algorithms were modelled: Support Vector Machine, Logistic Regression, K-Near Neighbor, Random Forest, and Decision Tree. The study estimated the hazard ratio for the Cox Proportional Hazard Model and drew the Kaplan-Meier curve to compare the survivor risk of being stunted between program beneficiaries and non-beneficiaries. Logistic regression was used to identify the nutrition programs related to stunting reduction. Precision, recall, F1 score, accuracy, and Area under the Curve (AUC) are the metrics that were used to evaluate each classifier's performance to find the best one.

RESULTS

Based on the provided data, the study revealed that the early childhood development (ECD) program (p-value = 0.041), nutrition sensitive direct support (NSDS) program (p-value = 0.03), ubudehe category (p-value = 0.000), toilet facility (p-value = 0.000), antenatal care (ANC) 4 visits (p-value = 0.002), fortified blended food (FBF) program (p-value = 0.038) and vaccination (p-value = 0.04) were found to be significant predictors of stunting reduction among under two children in Rwanda. Additionally, beneficiaries of early childhood development (p  < .0001), nutrition sensitive direct support (p = 0.0055), antenatal care (p = 0.0343), Fortified Blended Food (p = 0.0136) and vaccination (p = 0.0355) had a lower risk of stunting than non-beneficiaries. Finally, Random Forest performed better than other classifiers, with precision scores of 83.7%, recall scores of 90.7%, F1 scores of 87.1%, accuracy scores of 83.9%, and AUC scores of 82.4%.

CONCLUSION

The early childhood development (ECD) program, receiving the nutrition sensitive direct support (NSDS) program, focusing on households with the lowest wealth quintile (ubudehe category), sanitation facilities, visiting health care providers four times, receiving fortified blended food (FBF), and receiving all necessary vaccines are what determine the stunting reduction under two among the 17 districts of Rwanda. Finally, when compared to other models, Random Forest was shown to be the best machine learning (ML) classifier. Random forest is the best classifier for predicting the stunting reduction status of children under two years old.

Improving Parental Health Literacy in Primary Caregivers of 0- to 3-Year-Old Children Through a WeChat Official Account: Cluster Randomized Controlled Trial

Background

Parental health literacy is important to children's health and development, especially in the first 3 years. However, few studies have explored effective intervention strategies to improve parental literacy.

Objective

This study aimed to determine the effects of a WeChat official account (WOA)-based intervention on parental health literacy of primary caregivers of children aged 0-3 years.

Methods

This cluster randomized controlled trial enrolled 1332 caregiver-child dyads from all 13 community health centers (CHCs) in Minhang District, Shanghai, China, between April 2020 and April 2021. Participants in intervention CHCs received purposefully designed videos via a WOA, which automatically recorded the times of watching for each participant, supplemented with reading materials from other trusted web-based sources. The contents of the videos were constructed in accordance with the comprehensive parental health literacy model of WHO (World Health Organization)/Europe (WHO/Europe). Participants in control CHCs received printed materials similar to the intervention group. All the participants were followed up for 9 months. Both groups could access routine child health services as usual during follow-up. The primary outcome was parental health literacy measured by a validated instrument, the Chinese Parental Health Literacy Questionnaire (CPHLQ) of children aged 0-3 years. Secondary outcomes included parenting behaviors and children's health outcomes. We used the generalized linear mixed model (GLMM) for data analyses and performed different subgroup analyses. The β coefficient, risk ratio (RR), and their 95% CI were used to assess the intervention's effect.

Results

After the 9-month intervention, 69.4% (518/746) of caregivers had watched at least 1 video. Participants in the intervention group had higher CPHLQ total scores (β=2.51, 95% CI 0.12-4.91) and higher psychological scores (β=1.63, 95% CI 0.16-3.10) than those in the control group. The intervention group also reported a higher rate of exclusive breastfeeding (EBF) at 6 months (38.9% vs 23.44%; RR 1.90, 95% CI 1.07-3.38) and a higher awareness rate of vitamin D supplementation for infants younger than 6 months (76.7% vs 70.5%; RR 1.39, 95% CI 1.06-1.82). No significant effects were detected for the physical score on the CPHLQ, breastfeeding rate, routine checkup rate, and children's health outcomes. Furthermore, despite slight subgroup differences in the intervention's effects on the total CPHLQ score and EBF rate, no interaction effect was observed between these subgroup factors and intervention factors.

Conclusions

Using a WHO literacy model-based health intervention through a WOA has the potential of improving parental health literacy and EBF rates at 6 months. However, innovative strategies and evidence-based content are required to engage more participants and achieve better intervention outcomes.

Interventions with pregnant women, new mothers and other primary caregivers for preventing early childhood caries

BACKGROUND

Dental caries, a common chronic disease of childhood, is associated with adverse health and economic consequences for infants and their families. Socioeconomically disadvantaged children have a higher risk of early childhood caries (ECC). This review updates one published in 2019.

OBJECTIVES

To assess the effects of interventions undertaken with pregnant women, new mothers or other primary caregivers of infants in the first year of life, for preventing ECC (from birth to six years).

SEARCH METHODS

We searched Cochrane Oral Health's Trials Register, Cochrane Pregnancy and Childbirth's Trials Register, CENTRAL, MEDLINE (Ovid), Embase (Ovid), CINAHL EBSCO, the US National Institutes of Health Ongoing Trials Register (clinicaltrials.gov) and WHO International Clinical Trials Registry Platform (apps.who.int/trialsearch). The latest searches were run on 3 January, 2023.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing interventions with pregnant women, or new mothers and other primary caregivers of infants in the first year of life, against standard care, placebo or another intervention, reporting on a primary outcome: caries presence in primary teeth, dmfs (decayed, missing, filled primary surfaces index), or dmft (decayed, missing, filled teeth index), in children up to six years of age. Intervention types include clinical, oral health promotion/education (hygiene education, breastfeeding and other dietary advice) and policy or service.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed study eligibility, extracted data, assessed risk of bias, and assessed certainty of evidence (GRADE).

MAIN RESULTS

We included 23 RCTs (5 cluster-randomised), involving 25,953 caregivers (mainly mothers) and their children. Fifteen trials assessed oral health education/promotion interventions against standard care. Six trials assessed a clinical intervention for mother dentition, against placebo, or a different type of clinical intervention. Two trials assessed oral health/education promotion plus clinical intervention (for mother's dentition) against standard care. At most, five trials (maximum of 1326 children and 130 mothers) contributed data to any comparison. Enamel-only caries were included in the diagnosis of caries in some studies. For many trials, the risk of bias was unclear due to lack of methodological details reported. In thirteen trials, participants were socioeconomically disadvantaged. No trial indicated receiving funding that was likely to have influenced their results. Oral health education/promotion interventions Child diet and feeding practice advice versus standard care: We observed a probable 15 per cent reduced risk of caries presence in primary teeth with the intervention (RR 0.85, 95% CI 0.75 to 0.97; 3 trials; 782 participants; moderate-certainty evidence), and there may be a slightly lower mean dmfs (MD -0.29, 95% CI -0.58 to 0; 2 trials; 757 participants; low-certainty evidence); however, the evidence is very uncertain regarding the difference between groups in mean dmft (MD -0.90, 95% CI -1.85 to 0.05; 1 trial; 340 participants; very low-certainty evidence). Breastfeeding promotion and support versus standard care: We observed little or no difference between groups in the risk of caries presence in primary teeth (RR 0.96, 95% CI 0.89 to 1.03; 2 trials; 1148 participants; low-certainty evidence) and in mean dmft (MD -0.12, 95% CI -0.59 to 0.36; 2 trials; 652 participants; low-certainty evidence). dmfs was not reported. Child diet advice compared with standard care: We are very uncertain about the effect on the risk of caries presence in primary teeth (RR 1.08, 95% CI 0.34 to 3.37; 1 trial; 148 participants; very low-certainty evidence). dmfs and dmft were not reported. Oral hygiene, child diet and feeding practice advice versus standard care: The evidence is very uncertain about the effect on the risk of caries presence in primary teeth (RR 0.73, 95% CI 0.50 to 1.07; 5 trials; 1326 participants; very low-certainty evidence) and there maybe little to no difference in mean dmfs (MD -0.87, 95% CI -2.18 to 0.43; 2 trials; 657 participants; low-certainty evidence) and mean dmft (MD -0.30, 95% CI -0.96 to 0.36; 1 trial; 187 participants; low-certainty evidence). High-dose versus low-dose vitamin D supplementation during pregnancy: We are very uncertain about the effect on risk of caries presence in primary teeth (RR 0.99, 95% CI 0.70 to 1.41; 1 trial; 496 participants; very low-certainty evidence). dmfs and dmft were not reported. Clinical interventions (for mother dentition) Chlorhexidine (CHX, a commonly prescribed antiseptic agent) or iodine-NaF application and prophylaxis versus placebo: We are very uncertain regarding the difference in risk of caries presence in primary teeth between antimicrobial and placebo treatment for mother dentition (RR 0.97, 95% CI 0.80 to 1.19; 3 trials; 479 participants; very low-certainty evidence). No trial reported dmfs or dmft. Xylitol compared with CHX antimicrobial treatment: We are very uncertain about the effect on caries presence in primary teeth (RR 0.62, 95% CI 0.27 to 1.39; 1 trial, 96 participants; very low-certainty evidence), but we observed there may be a lower mean dmft with xylitol (MD -2.39; 95% CI -4.10 to -0.68; 1 trial, 113 participants; low-certainty evidence). No trial reported dmfs. Oral health education/promotion plus clinical interventions (for mother dentition) Diet and feeding practice advice for infants and young children plus basic dental care for mothers compared with standard care: We are very uncertain about the effect on risk of caries presence in primary teeth (RR 0.44, 95% CI 0.05 to 3.95; 2 trials, 324 participants; very low-certainty evidence) or on mean dmft (1 study, not estimable). No trial reported dmfs. No trials evaluated policy or health service interventions.

AUTHORS' CONCLUSIONS

There is moderate-certainty evidence that providing advice on diet and feeding to pregnant women, mothers or other caregivers with children up to the age of one year probably leads to a slightly reduced risk of early childhood caries (ECC). The remaining evidence is low to very-low certainty and is insufficient for determining which, if any, other intervention types and features may be effective for preventing ECC, and in which settings. Large, high-quality RCTs of oral health education/promotion, clinical, and policy and service access interventions, are warranted to determine the effects and relative effects of different interventions and inform practice. We have identified 13 ongoing studies. Future studies should consider if and how effects are modified by intervention features and participant characteristics (including socioeconomic status).

A Review on Maternal Parenting, Child's Growth Stunting, and Oral Health

Stunting has gained global attention as one of the most critical problems in public health. As the first and dominant figure in a child's life, the mother is responsible for determining the proper parenting behaviors to apply to maintain the child's physical health. Stunting is often associated with early childhood caries (ECC) and molar incisor hypomineralization, which can be manifested into each other through various mechanisms. Therefore, it is crucial to explore how far maternal parenting behaviors affect stunting and oral health. This study aims to determine which maternal parenting behaviors can affect stunting and oral health. A systematic search was used through PubMed and Google Scholar to search for published articles between 2011 and 2021. The articles analyze maternal parenting behaviors with stunting and poor oral health. Final analysis was used on 21 articles containing 18 cross-sectional studies, 2 cohort studies, and 1 randomized controlled trial. The result implied that the high prevalence of stunting and ECC is the combined result of prolonged breastfeeding practices (7 articles), poor complementary feeding practice (6 articles), high consumption of sugar (5 articles), and poor oral hygiene practices (5 articles). Maternal parenting styles in the aspect of fulfilling nutrition and maintaining oral health affect the occurrence of stunting and ECC in children.

A 2-arm randomized controlled study to improve the oral health of children living with HIV in Nigeria: Protocol and study design

Background

Good oral health is an integral part of overall child health. However, immune-deficient states like the presence of Human Immunodeficiency Virus (HIV) will compromise oral health and salivary bacterial composition, leading to adverse oral conditions. Nigeria has 1.9 million HIV-positive residents, and 0.2% of incident HIV infections occur among children below 15 years.

Aim

This study aims to determine through a randomized control study, the effect of an educational intervention on the oral health status and oral health-related quality of life (OHRQoL) of HIV-positive children presenting to five pediatric HIV clinics in Kano, Nigeria.

Methods/Design

This 2-arm randomized control study will be conducted in five pediatric HIV outpatient clinics in Kano State, Nigeria over a period of 6 months. Eligible participants will include 172 HIV-infected frequency matched children aged 8-16 years (they can self-implement the oral health intervention with minimal supervision from the caregivers) who will be randomized and allocated into control and intervention groups. The evaluation and oral health assessment will be carried out by five examiners who will be trained and calibrated.

Discussion

Our findings will help inform policies to improve the oral health and OHRQoL of HIV-positive Nigerian children and inform the need to integrate oral health care services into HIV programs in similar settings.

Children oral health and parents education status: a cross sectional study

INTRODUCTION

Oral diseases are common and affect millions of people worldwide. They can range from mild and easily treatable conditions to more severe and serious diseases. Proper oral hygiene and regular dental monitoring are essential for maintaining good oral health. When it comes to children's health and well-being, parents' education level plays a critical role. Research has shown that parents' higher educational attainment is associated with better health outcomes for their children. Our aim is to evaluate whether parents' education level and employment influence children oral health and its impact on the family.

METHODS

We enrolled consecutively healthy subjects aged between 0-16 and their parents at the Dental Clinic of the University of Campania "L. Vanvitelli". The Italian version of the ECOHIS (I-ECOHIS) was administered to parents of the enrolled subjects referred to the Dental Clinic of the University of Campania "L. Vanvitelli". Linear regression models, adjusted for age and sex, were used to explore the association between parents' employment or education level and the ECOHIS scores. Statistical significance was accepted when p value < 0.05.

RESULTS

We found a significative association of a higher I-ECOHIS total score (coeff. 4.04244; CI 95%: 1.530855-6.554026; p = 0,002) and higher I-ECOHIS children section score (coeff. 3.2794; CI 95%: 1.29002-5.268; P = 0,002) and the father unemployed status. We also found that a higher education level of the father was associated with a lower ECOHIS total score (coeff. -1.388; IC 95%: -2.562115--0.214 p = 0.021) and a higher education level of the mother was associated with a lower ECOHIS in children section (coeff. -0.972; IC95%: -1.909356-0.034; p = 0.042).

CONCLUSIONS

Father unemployed status and a lower educational level for both parents may negatively affect oral health status.

Factorial structure and measurement invariance of the Chinese version of the Oral Health Impact Profile-14 among clinical populations and non-clinical populations: an evidence for public oral investigations

OBJECTIVE

Oral health-related quality of life (OHRQoL) is a multidimensional concept that is commonly used to examine the impact of oral health status on quality of life. The purpose of this study was to examine the optimal factor model of the Chinese version of the Oral Health Impact Profile (OHIP-14) questionnaire in clinical populations, measurement invariance across clinical status and gender cohorts. This would ensure equal validity of the Chinese version of OHIP-14 in different populations and further support public oral investigations.

METHODS

The Chinese version of OHIP-14 was used to investigate 490 dental patients and 919 college students. Confirmatory factor analysis (CFA), item analysis and reliability, measurement invariance, and the t-test were used for data analyses.

RESULTS

We found that the 7-factor structure had the best-fit index in the sample (CFI = 0.970, TLI = 0.952; SRMR = 0.029, RMSEA = 0.052(0.040,0.063)). The reliability of the scales was satisfactory (Cronbach's α = 0.942). The error variance invariance fitted the data adequately in measurement invariance, indicating that measurement invariance is acceptable both across the clinical and non-clinical populations (∆CFI=-0.017, ∆RMSEA = 0.010) and across genders in the clinical population (∆CFI = 0.000, ∆RMSEA=-0.003). T-test for scores showed that the clinical populations scored significantly higher than the non-clinical populations, as did the overall score (t = 7.046, p < 0.001, d = 0.396), in terms of functional limitation (t = 2.178, p = 0.030, d = 0.125), physical pain (t = 7.880, p < 0.001,d = 0.436), psychological discomfort (t = 8.993, p < 0.001, d = 0.514), physical disability (t = 6.343, p < 0.001, d = 0.358), psychological disability (t = 5.592, p < 0.001, d = 0.315), social disability (t = 5.301, p < 0.001,d = 0.304), social handicap (t = 4.452, p < 0.001, d = 0.253), and that in the non-clinical populations, females scored significantly higher than males, as did in terms of physical pain (t = 3.055, p = 0.002, d = 0.280), psychological discomfort (t = 2.478, p = 0.014, d = 0.222), and psychological disability (t = 2.067, p = 0.039, d = 0.188).

CONCLUSION

This study found that the Chinese version of OHIP-14 has measurement invariance between the clinical and non-clinical populations and across genders in the clinical populations, and can be widely used in OHRQoL assessment for public oral investigations.

Hygiene Practices and Early Childhood Development in the East Asia-Pacific Region: A Cross-Sectional Analysis

Poor hygiene might be a risk factor for early childhood development (ECD). This study investigated the associations of three hygiene practices ('wash hands before a meal,' 'wash hands after going to the toilet,' and 'brush teeth'), separately and combined, with ECD. Six thousand six hundred ninety-seven children (4 [0.8] years) from the East Asia-Pacific Early Child Development Scales validation study were included in this cross-sectional analysis. The hygiene variables were recoded to have comparable values as 'always,' 'sometimes,' and 'never.' These variables were then grouped to create combined categories. The binary outcome variables, poor ECD, were defined as a score < age-specific 25th centile. Modified Poisson regression models were used to analyse the associations. Data collection was performed between 2012 and 2014, and the analyses were conducted in April 2022. Compared with children who 'always' washed their hands before a meal, those who did it 'sometimes' (Prevalence Ratio [PR]: 1.30 [95% CI: 1.16-1.46]) or 'never' (PR: 1.35 [1.18-1.55]) had a higher likelihood of poorer overall development. Comparable results were identified for the other two hygiene practices and the other four domain-specific outcomes (p < 0.05). Compared with children who always followed the three hygiene practices, the likelihood of poor overall ECD increased as the combined hygiene practice decreased among children with poor hygiene practices (PRnever: 1.67 [1.40-2.00]; PRrarely: 1.49 [1.30-1.71]; PRsometimes: 1.30 [1.14-1.49]). Children who did not always follow good hygiene practices had a higher likelihood of poor ECD independently of sociodemographic factors. Considering these findings, future hygiene practice interventions and trials should consider including ECD outcomes.

Factors influencing adoption of oral health promotion by antenatal care providers in Moyo district, North-Western Uganda

BACKGROUND

Oral health promotion (OHP) during pregnancy is an important global public health and basic human right issue related to quality of life. Several statements and guidelines have been published emphasizing the need for improved oral health care of pregnant mothers, prenatal care providers have missed this critical opportunity. In this study, we assessed factors influencing adoption of oral health promotion by antenatal care providers.

MATERIALS AND METHODS

A descriptive cross-sectional study design that employed both quantitative and qualitative data collection methods and analysis. 152 samples determined using Yamane's 1967 and stratified sampling technique was used. Three FGDs and six KI interviews were held. Univariate, bivariate and multivariate analyses were done using SPSS (20.0) and ATLAS Ti for qualitative analysis.

RESULTS

Adoption of OHP was low 28% (42). Factors influencing adoption were age of respondents (OR = 0.066, 95%CI = 0.009-0.465, p = 0.006*), level of care of health facility (OR = 0.050, 95%CI = 0.008-0.322, p = 0.002*), good understanding between dentists and ANC providers (OR = 0.283, 95%CI = 0.084-0.958, p = 0.042*), availability of practice guideline for OHP in ANC (OR = 0.323, 95%CI = 0.108-0.958, p = 0.043*), number of years at work (p = 0.084), being knowledgeable (OR = 2.143, 95%CI = 0.864-5.311, p = 0.100), having skills to advance OHP(OR = 0.734, 95%CI = 0.272-1.984, p = 0.542), Management being good at influencing new practices (OR = 00.477.734, 95%CI = 0.227-2.000, p = 0.477). More emphasis on national and local of oral health issues, continuous staff training on oral health, dissemination of National oral health policy (NOHP) were some of key issues that emerged from the qualitative results.

CONCLUSION

Adoption of OHP was low. This was attributed to age, number of years spent at work, level of health facility, having good understanding between dentists and ANC providers, availability of practice guidelines, dissemination of National oral health policy, continuous staff training. We recommend the current NOHP to be reviewed, develop prenatal OHC guidelines, enhance the capacity of ANC providers through training, collaboration with dentists and launch official adoption of OHP.

Integrating Oral Health into Primary Health Care: A Systematic Review of Oral Health Training in Sub-Saharan Africa

Background

Globally, oral health training has shown positive influence on knowledge, competency and practices for both oral and non-oral health-care workers towards integration of oral health into primary health care (PHC). Sub-Saharan Africa has very divergent social-cultural-political-economic settings. Since healthcare is contextual, it is necessary to review oral health training programs in this region to establish if their formulation, implementation and evaluation are context-reliant.

Objective

To assess if oral health trainings aimed at integrating oral health into PHC in sub-Saharan Africa were context-reliant.

Methodology

The reviewers searched five electronic databases and WHO sites. Selection of publications was done using the PRISMA framework. Oral health training programs for oral and non-oral health-care workers in sub-Saharan Africa published in English language between year 2001 and 2020 were included in the study.

Findings

Only 4 (0.8%) of the original 512 publications for oral health-care workers and 9 (1.5%) of the 613 for non-oral health-care workers publications met the inclusion criteria. Countries established and/or increased number of dental schools, 1 university adopted competency-based curriculum and 2 introduced community rotations. Dental auxiliaries varied by cadre, training duration and scope of practice. Non-oral health-care workers training programs used diverse approaches like pre-service, workshops and printed materials. Target groups for the trainings varied from nurses, traditional healers, health promotion officers to community health volunteers. Evaluations were done mainly using pre-post or quasi-experimental studies. Outcomes of interest varied from level of knowledge, services provision, early childhood caries, oral health seeking behavior and oral hygiene practices.

Conclusion

Oral health training for integration of oral health into PHC in sub-Saharan Africa varied by targeted cadre, training methods and evaluation method and scope. It was thus context-reliant. More programs are necessary to accommodate other training approaches, evaluation methods and other health-care cadres in the region.

Intensive Health Care plus Vitamin D Administration Benefits the Growth and Development of Young Children and Reduces the Incidence of Nutritional Disorders

This study was intended to assess the effect of intensive health care plus vitamin D administration on the growth, development, and nutritional status of young children. Totally, 131 young children who were admitted to Shiyan Maternal and Child Health Care Hospital from January 2020 to January 2021 were included and assigned via the random number table method at a ratio of 1 : 1 : 1 to receive either vitamin D administration (vitamin D group, n = 42), intensive health care (IHC) (IHC group, n = 44), or vitamin D administration plus intensive health care (combination group, n = 45). All children received a normal diet and routine care. After the intervention, all children showed robust improvement in their height, weight, neuropsychological development, and nutritional status, in which the combination therapy was associated with better outcomes in terms of physical development, neuropsychological development, and nutritional status, and a higher serum 25-hydroxyvitamin D3 (25-(OH)D3) level of the children versus monotherapy. Children receiving combined therapy had a significantly lower incidence of nutritional disorders than those receiving single therapy. Intensive health care plus vitamin D benefits the growth and development of young children and reduces the incidence of nutritional disorders in children.

Child saliva microbiota and caries: a randomized controlled maternal education trial in rural Uganda

Undernutrition is a public health challenge in sub-Saharan countries, including Uganda. In a previous randomized controlled trial (RCT) with a nutrition, hygiene and stimulation education intervention among mothers of 6 months’ old children, we found less caries in the intervention group when the children were 36 months of age. We now examined the effects of (i) the intervention on the microbiota, (ii) microbiota on caries, and (iii) the intervention and microbiota on caries. The original RCT comprised 511 mother/child pairs whereas in the current study we had access to data from 344/511 (67%) children aged 36 months. The saliva microbiota was determined using 16S rRNA gene sequencing. Carious lesions (a proxy for dental health) were identified using close-up intra-oral photographs of the upper front teeth. Statistical models were used to determine host-microbiota associations. The intervention had a significant effect on the microbiota, e.g. an increase in Streptococcus abundance and decreases in Alloprevotella and Tannerella. Significant associations between the microbiota and dental caries were identified: Positive associations of Capnocytophaga and Tannerella suggest that these taxa may be deleterious to dental health while negative associations of Granulicatella, Fusobacterium, and Abiotrophia suggest taxa potentially beneficial or benign contributors to dental health. Based on taxonomic profiles, the effects of the intervention and microbiota on dental health may be independent of one another. Educational interventions with emphasis on nutrition and oral hygiene may provide a feasible strategy to decrease progression of childhood caries in low-resource settings.

Does Dental Caries Increase Risk of Undernutrition in Children?

INTRODUCTION

A systematic review of the evidence on the impact of dental caries on malnutrition risk in children was conducted.

OBJECTIVES

To systematically review published evidence pertaining to the effect of dental caries severity and prevalence on risk of wasting or stunting in children.

METHODS

Four questions relating to caries of the permanent dentition, primary dentition, early childhood caries (ECC), and severe ECC as a risk factor for undernutrition were set. The target population was children aged 0 to 18 y from any country. Data sources included MEDLINE and Embase. All human epidemiological studies were included. Quality assessment excluded lowest-quality studies. Evidence synthesis by vote counting was depicted using harvest plots. A best available evidence approach was applied to narrative synthesis. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

RESULTS

Of the 2,690 studies identified, 447 were screened in duplicate; of these, 117 underwent quality assessment, resulting in 46 included studies, of which 38 were included in vote counting (3 quasi-experimental, 1 cohort, 1 case control, and 33 cross-sectional studies). For the permanent dentition, findings were mixed; the balance of data showed no association between caries prevalence (7/11 studies) or severity (8/17 studies) with wasting. For the primary dentition, the balance of data showed a positive association between caries prevalence (10/15 studies) and severity (12/15 studies) with wasting, as well as between-caries prevalence (4/5 studies) and severity (6/6 studies) with stunting. Considering ECC only did not alter this pattern of findings.

CONCLUSION

The balance of evidence suggests that dental caries in the primary dentition is associated with undernutrition. There is a need for well-designed trials on the impact of caries rehabilitation on growth trajectories of children from low- and middle-income countries and for prospective studies of the impact of caries severity on both stunting and wasting to confirm causality.

KNOWLEDGE TRANSFER STATEMENT

The results of this study can be used by policy makers when considering the importance of oral health in addressing the United Nations Sustainable Development Goal to end all forms of malnutrition. The findings suggest that dental caries in the primary dentition may impair children's healthy weight gain. The findings indicate that higher-quality data are required to confirm a causal relationship and thus inform funding bodies of the need for research, especially in low- and middle-income countries, to substantiate the current knowledge and inform clear and accurate policy statements.

Stunting Prevention and Control Program to Reduce the Prevalence of Stunting: Systematic Review Study

BACKGROUND: Stunting is a condition in which the occurrence of failure to thrive in children as a result of chronic malnutrition so that the child is too short for his age. The prevalence of stunting in children under five in Indonesia is higher than the prevalence of stunting in the world. One of the impacts of stunting is the occurrence of developmental barriers, where if this is not prevented it will have an impact on the less than optimal performance of children in school and the long-term impact can be a decrease in the quality of human resources. AIM: This study aims to systematically identify stunting prevention and control programs to reduce the prevalence of stunting. METHODS: The method used in this study is the Systematic Review (SR). SR is a method that identifies, assesses, and interprets findings on a research topic to answer predetermined research questions. The keywords used to search for articles on electronic databases are ProQuest, Scinapse, PubMed, and Google Search. The keywords used are “stunting,” “parenting,” “parenting AND Stunting,” “stunting prevention,” “stunting prevention,” “stunting in lower and middle income countries,” “stunting and global programs,” and “stunting and Indonesia.” “Stunting and Asia Region” obtained from the ProQuest, Scinapse, PubMed, and Google Search database. RESULTS: Based on the identification results of this study, there are several forms of programs and interventions to prevent and control stunting that have been proven to be successful in reducing the prevalence of stunting, namely: CARING Trial, COWPEA, The Lulun Project, Rang-Din Nutrition Study, Tubaramure, NEO-MOM, Preparing for Life, Integrated Child Development Services, Early childhood caries, Small-Quantity, Lipid-Based Nutrient Supplements, Handwashing With Soap and Total Sanitation and Sanitation Marketing, PROCOMIDA, Community-Based Participatory Nutrition Promotion Program, Promote Children’s Growth and Development, Community-Based Growth Monitoring Including Nutritional Supplementation, Child Development Agents, Lady Health Worker program, ready-to-use supplementary foods, and Supporting Father Involvement, Positive Deviance/Hearth, JiVitA-3. CONCLUSION: From planning, conducting and reporting, it can be concluded that the intervention as an effort to prevent and control stunting had a significant effect between the intervention group and the treatment group and the control group which was only given normal treatment even without any treatment.

The Current Strategies in Controlling Oral Diseases by Herbal and Chemical Materials

Dental plaque is a biofilm composed of complex microbial communities. It is the main cause of major dental diseases such as caries and periodontal diseases. In a healthy state, there is a delicate balance between the dental biofilm and host tissues. Nevertheless, due to the oral cavity changes, this biofilm can become pathogenic. The pathogenic biofilm shifts the balance from demineralization-remineralization to demineralization and results in dental caries. Dentists should consider caries as a result of biological processes of dental plaque and seek treatments for the etiologic factors, not merely look for the treatment of the outcome caused by biofilm, i.e., dental caries. Caries prevention strategies can be classified into three groups based on the role and responsibility of the individuals doing them: (1) community-based strategy, (2) dental professionals-based strategy, and (3) individual-based strategy. The community-based methods include fluoridation of water, salt, and milk. The dental professionals-based methods include professional tooth cleaning and use of varnish, fluoride gel and foam, fissure sealant, and antimicrobial agents. The individual-based (self-care) methods include the use of fluoride toothpaste, fluoride supplements, fluoride mouthwashes, fluoride gels, chlorhexidine gels and mouthwashes, slow-release fluoride devices, oral hygiene, diet control, and noncariogenic sweeteners such as xylitol. This study aimed to study the research in the recent five years (2015–2020) to identify the characteristics of dental biofilm and its role in dental caries and explore the employed approaches to prevent the related infections.

A scoping review of current practices on community engagement in rural East Africa: Recommendations for snakebite envenoming

Community empowerment and engagement is one of the four strategic aims highlighted in the WHO strategy to prevent and control snakebite envenoming. Inappropriate health-seeking behaviours contribute to adverse outcomes, and community engagement is key in driving behavioural change. WHO has highlighted East Africa as a geographical area of concern for snakebite envenoming. The overall aim of the project is to develop a community engagement toolkit for snakebite envenoming and other NTDs. The objective of this scoping review was to identify current practices in recent community engagement in rural East Africa; the applicability of these results to snakebite envenoming are discussed. PubMed, Web of Science, PsycINFO and Google Scholar were searched from 1 January 2017 to 3 September 2020. Search terms were used to identify publications which related to rural communities and health or disease, for both humans and animals. After reviewing the full papers for all geographical areas, 112 publications were included, 30 of which were conducted in East Africa. Papers included nine different countries and covered a broad range of health topics; notably, water, sanitation and hygiene, nutrition, and maternal and child health. Only one publication considered animal health. The most common form of engagement was in the context of a group meeting, lecture, presentation, discussion or question and answer session (63.3%). A variety of locations within the community were used to engage with people, the most common being an individual's household (23.3%). Communication factors was the key influencer for engagement, both positively and negatively. Key barriers to engagement include local languages and health beliefs, literacy levels, mobile phone ownership and the level of mobile Internet coverage, burden of agricultural work and weather conditions. This study provides an extensive overview of recent public health community engagement in East Africa, which will serve as a useful resource for any group seeking to plan an intervention in remote and rural areas in East Africa. Furthermore, it serves as a guide to help tailor community engagement to snakebite envenoming.

Interventions with pregnant women, new mothers and other primary caregivers for preventing early childhood caries

BACKGROUND

Dental caries is one of the most common chronic diseases of childhood and is associated with adverse health and economic consequences for infants and their families. Socioeconomically disadvantaged children have a higher risk of early childhood caries (ECC).

OBJECTIVES

To assess the effects of interventions with pregnant women, new mothers or other primary caregivers of infants in the first year of life, for preventing ECC (from birth to six years of age).

SEARCH METHODS

Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 14 January 2019), Cochrane Pregnancy and Childbirth Group's Trials Register (to 22 January 2019), Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Register of Studies, to 14 January 2019), MEDLINE Ovid (1946 to 14 January 2019), Embase Ovid (1980 to 14 January 2019) and CINAHL EBSCO (1937 to 14 January 2019). The US National Institutes of Health Trials Registry (ClinicalTrials.gov) and World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. No restrictions were placed on language or publication status.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing one or more interventions with pregnant women, mothers, or other caregivers of infants in the first year of life (intervention types included clinical, oral health education/promotion such as hygiene education, breastfeeding and other dietary advice, and policy or health service), versus standard care or placebo or another intervention. For inclusion, trials had to report at least one caries outcome.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial eligibility, extracted data, assessed risk of bias, and assessed certainty of evidence using the GRADE approach.

MAIN RESULTS

We included 17 RCTs (4 cluster-randomised), involving 23,732 caregivers (mainly mothers) and their children. Eleven RCTs assessed four oral health education/promotion interventions against standard care: child diet advice, child diet and feeding practice advice, breastfeeding promotion and support, and oral hygiene with child diet and feeding practice advice. Six trials assessed clinical interventions in mother's dentition, four trials chlorhexidine (CHX, a commonly prescribed antiseptic agent) or iodine-NaF application and prophylaxis versus placebo, and two trials xylitol against CHX or CHX + xylitol. At most, three trials (maximum of 1148 children and 130 mothers) contributed data to any comparison. For many trials, risk of bias was judged unclear due to lack of methodological details reported, and there was high risk of attrition bias in some trials. None of the included trials indicated receiving funding that is likely to have influenced their results. The trials were performed in high-, middle- and low-income countries. In nine trials, participants were socioeconomically disadvantaged. For child diet and feeding practice advice versus standard care, we observed a probable 15 per cent reduced risk of caries presence in primary teeth with the intervention (RR 0.85, 95% CI 0.75 to 0.97; 3 trials; 782 participants; moderate-certainty evidence), and there may be a lower mean dmfs (decayed, missing, filled primary surfaces) score (MD -0.29, 95% CI -0.58 to 0; 2 trials; 757 participants; low-certainty evidence); however, we are uncertain regarding the difference between the groups in mean dmft (decayed, missing, filled teeth) score (MD -0.90, 95% CI -1.85 to 0.05; 1 trial; 340 participants; very low-certainty evidence). For breastfeeding promotion and support versus standard care, we observed that there may be little or no a difference between groups in the risk of caries presence in primary teeth (RR 0.96, 95% CI 0.89 to 1.03; 2 trials; 1148 participants; low-certainty evidence), or mean dmft score (MD -0.12, 95% CI -0.59 to 0.36; 2 trials; 652 participants; low-certainty evidence). Dmfs was not reported for this comparison. We are uncertain whether child diet advice only compared with standard care reduces risk of caries presence in primary teeth (RR 1.08, 95% CI 0.34 to 3.37; 1 trial; 148 participants; very low-certainty evidence). Dmfs and dmft were not reported for this comparison. For oral hygiene, child diet and feeding practice advice versus standard care, we observed little or no reduced risk of caries presence in primary teeth (RR 0.91, 95% CI 0.75 to 1.10; 2 trials; 365 participants; low-certainty evidence), and are uncertain regarding difference between the groups in mean dmfs score (MD -0.99, 95% CI -2.45 to 0.47; 1 trial; 187 participants; very low-certainty evidence) and dmft score (MD -0.30, 95% CI -0.96 to 0.36; 1 trial; 187 participants; very low-certainty evidence). We observed there may be little or no difference in risk of caries presence in primary teeth between antimicrobial and placebo treatment in mother's dentition (RR 0.97, 95% CI 0.80 to 1.19; 3 trials; 479 participants; very low-certainty evidence). No trials assessing this comparison reported dmfs or dmft. For xylitol compared with CHX antimicrobial treatment, we observed there may be a lower mean dmft score with xylitol (MD -2.39; 95% CI -4.10 to -0.68; 1 trial, 113 participants; low-certainty evidence); however, we are uncertain regarding the difference between groups in caries presence in primary teeth (RR 0.62, 95% CI 0.27 to 1.39; 1 trial, 96 participants; very low-certainty evidence). Neither trial evaluating this comparison reported dmfs. No trials assessed a health policy or service intervention.

AUTHORS' CONCLUSIONS

Moderate-certainty evidence suggests that providing advice on diet and feeding to pregnant women, mothers or other caregivers with children up to the age of one year probably leads to a slightly reduced risk of early childhood caries (ECC). The remaining evidence is low to very low certainty and is insufficient for determining which, if any, other interventions types and features may be effective for preventing ECC. Large, high-quality RCTs of oral health education/promotion, clinical, and policy and service access interventions, are warranted to determine effects and relative effects of different interventions and inform practice. We have identified 12 studies currently in progress. Those designing future studies should describe the intervention components, setting and participants, consider if and how effects are modified by intervention features and participant characteristics, and adopt a consistent approach to measuring and reporting ECC.

Follow-up of Intervention to Prevent Dental Caries Among Indigenous Children in Australia: A Secondary Analysis of a Randomized Clinical Trial

Importance

For an intervention delivered in early childhood to have meaningful translational effect, long-term follow-up is necessary, especially among underserved indigenous children among whom preventable dental disease is common.

Objectives

To test the long-term effectiveness of an early-childhood dental intervention through a follow-up at age 5 years among Aboriginal children in Australia.

Design, Setting, and Participants

This secondary analysis of a randomized clinical trial followed up on participants of the Baby Teeth Talk Study, a 2-group parallel, outcome assessor-blinded, randomized clinical trial conducted among Aboriginal children in South Australia, Australia. Participants included 448 mother or caregiver-child dyads who were enrolled in the Baby Teeth Talk trial between February 2010 and May 2011 and were randomized in the present trial to the immediate intervention group or the delayed intervention group. Intention-to-treat principles were used for all data analyses to estimate the effect of the intervention on dental caries experience. Data analysis was performed from April 10 to May 27, 2019.

Interventions

The intervention comprised 4 services to participants: (1) dental care to mothers during pregnancy, (2) application of fluoride varnish to children's teeth, (3) anticipatory guidance in the form of oral health educational packages, and (4) motivational interviewing for pregnant mothers and children at ages 6, 12, and 18 months in the immediate intervention group and at ages 24, 30, and 36 months in the delayed intervention group.

Main Outcomes and Measures

The primary outcome was the mean number, in the primary dentition, of decayed, missing, or filled teeth (dmft) at age 5 years. Individual components of the dmft index were examined, as was the prevalence of dmft greater than 0.

Results

Of the 449 Aboriginal mothers and children recruited, 223 (49.7%) were randomized to the immediate intervention group and 225 (50.1%) to the delayed intervention group. The mean dmft at age 5 years was 2.10 (95% CI, 2.04 to 2.16) for children in the immediate intervention group and 2.91 (95% CI, 2.83 to 3.00) for children in the delayed intervention group (adjusted mean difference, -1.02; 95% CI, -1.81 to -0.22). When considering children in nonmetropolitan locations, the differences were stark; the mean dmft was 2.46 (95% CI, 2.38-2.54) for children in the immediate intervention group and 3.65 (95% CI, 3.53 to 3.78) for children in the delayed intervention group, with an adjusted mean difference of -1.52 (95% CI, -2.61 to -0.43). Most of this difference was accounted for by missing teeth, with the mean number of missing teeth of children in the immediate intervention group living in nonmetropolitan locations being 0.29 (95% CI, 0.27 to 0.31) compared with 1.02 (95% CI, 0.96 to 1.07) for their counterparts in the delayed intervention group. A 3-fold difference was observed in the percentage of missing teeth greater than 0 between children in the immediate intervention group and those in the delayed intervention group (10.8 [95% CI, 10.2 to 11.4] vs 31.0 [95% CI, 30.1 to 31.8]).

Conclusions and Relevance

This trial found that a multifaceted initiative to reduce early-childhood caries continued to be efficacious in participating indigenous children aged 5 years, especially those residing in nonmetropolitan locations and with teeth missing because of dental disease.
