Added Sugar and Dental Caries in Children: A Scientific Update and Future Steps

Factors Associated With Dental Caries in Primary Teeth of 5- and 6-Year-Old Polish Children

BACKGROUND

Caries in primary teeth remain a common health issue.

AIM

To identify oral health behaviours which significantly affect dental caries in children aged 5-6 years.

DESIGN

A national cross-sectional study of 1892 children integrated dental examinations and a questionnaire regarding socio-economic factors and oral health habits. Caries indices were calculated. The analyses included t- and chi-square tests, Spearman's correlation, bivariate and multivariate logistic regression (p < 0.05).

RESULTS

The majority of children (79.3%) had caries; mean dmft was 4.68 ± 4.05; dmfs-9.12 ± 10.74 and ft/ft. + dt-0.20 ± 0.31. There were correlations between mother's education, her knowledge of oral health, financial burden, the frequency of dental appointments and the treatment (p < 0.001). The dmft indices were correlated with postponing dental appointments and presenting with pain. The association between the treatment index, oral hygiene habits (parental-supervised toothbrushing twice a day, using fluoridated toothpaste) and dietary practices (restrictions of sugar intake, fruit juices and starchy foodstuffs) was found, even after socio-economic confounding factors were introduced.

CONCLUSION

The first years of a child's life are a period when the foundations of adult lifestyle choices are shaped. Parents should be aware of the importance of dental visits, nutritional counselling and proper oral care. The assessment of risk factors related to families is indispensable when prophylactic programmes are implemented.

Associations of body roundness index and sugar-sweetened beverage consumption with psychological symptoms in adolescents: a multicenter cross-sectional survey based on Chinese adolescents aged 12-18 years old

Background

Adolescent psychosocial symptoms continue to rise, negatively affecting academic performance and future achievement, and have become an important public health issue of common concern worldwide. However, few studies have been conducted on the association between body roundness index (BRI) and sugar-sweetened beverage (SSB) consumption and psychological symptoms in Chinese adolescents. The present study may provide implications for the intervention and prevention of psychological symptoms in Chinese adolescents.

Methods

In this study, 47,520 adolescents aged 12-18 years from six geographic regions of China were assessed cross-sectionally for BRI, SSB consumption, and psychological symptoms in 2023. Independent samples t-tests, chi-square tests, logistic regression analyses, and ordered logistic regression analyses were used to compare and analyze the associations that existed between BRI and SSB consumption and psychological symptoms among Chinese adolescents.

Results

The BRI of Chinese adolescents aged 12-18 years was (2.03 ± 0.94). The proportions of adolescents with SSB consumption ≤1 times/week, 2-3 times/week, and ≥ 4 times/week were 33.2, 52.0, and 14.7%, respectively, and the differences were statistically significant in comparison (X 2 value of 597.860, p < 0.001). The prevalence of psychological symptoms among Chinese adolescents was 19.2%. The prevalence rates of emotional problems, behavioral problems, and social adjustment difficulties were 26.1, 25.2, and 16.1%, respectively. After adjusting for relevant covariates, ordered logistic regression analysis showed that with BRI quartiles Q1 and SSB consumption ≤1 times/week as the reference group, the adolescents in the group with BRI quartiles of Q4 and SSB consumption ≥4 times/week (OR = 2.01, 95% CI: 1.77-2.30) had the highest risk of developing psychological symptoms (p < 0.001).

Conclusion

There is an association between BRI and SSB consumption with psychological symptoms in Chinese adolescents. Chinese adolescents with higher BRI and SSB consumption were at higher risk of developing psychological symptoms. In the future, the increase in BRI and SSB consumption should be effectively controlled to prevent or reduce the occurrence of psychological symptoms.

Sociodemographic and clinical factors associated with early childhood caries in Peruvian pre-schoolers

BACKGROUND

Early childhood caries (ECC) is a highly prevalent oral disease among children worldwide, arising from multiple contributing factors. This study aimed to investigate the sociodemographic and clinical factors associated with ECC in preschool children attending a hospital in Ica, Peru.

METHODS

This observational cross-sectional study involved 186 children evaluated during two dental health campaigns organised by a hospital in Ica, Peru. Oral examinations were conducted by two trained paediatric dentists, while haemoglobin levels were measured by two nurses. Mothers or caregivers completed questionnaires to provide relevant sociodemographic and behavioural data. Multiple logistic regression analyses were conducted to identify variables significantly associated with ECC (p < 0.05). The maximum likelihood method was used to assess the contribution of demographic, clinical and other factors-such as oral hygiene and cariogenic diet-using odds ratios (ORs) and regression coefficients to indicate the magnitude and direction of their effects.

RESULTS

The prevalence of ECC was 76.88%. Among the children, 50.54% were male, with a mean age of 4.44 ± 0.87 years. Most participants had poor oral hygiene (63.98%), while 82.26% of children with anaemia had reduced haemoglobin levels. The mean monthly family income was USD 376.35 ± 168.96. Mothers or caregivers reported brushing their children's teeth twice daily (56.99%) and giving sweets one to two times daily (79.03%). Factors significantly associated with ECC included the child's age (OR = 3.32; 95% CI, 1.68-6.58), haemoglobin level (OR = 0.43; 95% CI, 0.25-0.72), monthly family income (OR = 0.99; 95% CI, 0.9972-0.9998) and mother/caregiver education (OR = 0.13; 95% CI, 0.03-0.52). Additionally, dental brushing frequency (OR = 0.13; 95% CI, 0.02-0.65) and sweet consumption (OR = 4.98; 95% CI, 1.05-23.56) were identified as associated behaviours.

CONCLUSION

The findings demonstrate that ECC is associated with a child's age, monthly family income, mother/caregiver education level, haemoglobin level, brushing frequency and sweet consumption.

Impact of Free Sugar Consumption on Dental Caries: A Cross-Sectional Analysis of Children in the United States

Background/Objectives: The excessive consumption of free sugars adversely impacts health, contributing to systemic disorders and significantly increasing the risk of dental caries. Children are particularly vulnerable to dental caries due to their dietary habits and oral hygiene practices. This study aimed to examine the relationship between sugar intake and dental caries experience in a sample of children aged 6-12 years. Methods: Data were analyzed from the National Health and Nutrition Examination Survey (NHANES) covering the years 2011-2016. This cross-sectional study utilized nationally representative data from NHANES, which provides comprehensive health assessments on the U.S. population. This study focused on 3658 children aged 6-12 years. Free sugar intake and its association with dental caries were evaluated using the Decayed, Missing, and Filled Teeth (DMFT) index, a widely accepted measure for assessing cumulative caries experience in permanent teeth. Demographic and socioeconomic factors were also accounted for. The sample primarily consisted of generally healthy children, with mild to moderate health conditions included in the analysis. Results: The average Decayed, Missing, and Filled Teeth (DMFT) score was 1.69 (SD = 2.61). Untreated dental caries affected 19.1% of the sample, with disproportionately higher rates observed among Mexican American children (23.8%), children from lower socioeconomic backgrounds (24.2%), those with less-educated parents (25.1%), and overweight children (22.9%). Mean daily free sugar intake was 72.46 g (SD = 50.45), with significant variations across race/ethnicity, parental education, and gender. A statistically significant association was found between free sugar intake and dental caries in U.S. children (p < 0.001). Conclusions: Free sugar intake is strongly associated with an increased risk of dental caries. Disparities in caries prevalence were evident based on race/ethnicity, socioeconomic status, and parental education levels. Regulating sugar intake and promoting dietary education are effective strategies to reduce the risk of dental caries and improve oral health outcomes among children.

Oral Hygiene, Dietary Habits, and Saliva Properties in Relation to the Decayed, Missing, and Filled Teeth Index of Dental Students: A Pilot Study

Background and Objectives: Caries development is associated with poor oral hygiene, inadequate dietary habits, quantitative and qualitative food content, and a high level of bacterial plaque. Physical and chemical changes in saliva composition and particularly changes in its buffering capability play a significant role in caries development. This study aimed to determine the predictors of poor oral health among a sample of second-year dental students. Materials and Methods: The oral health of students was estimated with clinical examination and the DMFT index. The interview included questions about demographics status (gender, age), a dietary habits questionnaire, questions about oral hygiene, and a demonstration of tooth brushing technique. Unstimulated saliva samples were collected to measure buffering capacity and pH. Results: Almost half of the students have a low level of caries experience (46.7%), followed by a slightly smaller number having a medium level (41.3%), while one in eight students (12.0%) demonstrates a high level of caries experience. Male students have a statistically higher DMFT index 5.7 ± 1.2 than female participants 4.5 ± 0.5 (p = 0.036). Significant predictors for the DMFT index score in students were milk [β-coefficient = -0.338, p = 0.011] and yoghurt [β-coefficient = 0.284, p = 0.040] consumption. All students brushed their teeth two or more times during the day, usually after waking up before breakfast and before bedtime. Most students (85.3%) apply the proper tooth brushing technique, with female students applying it more frequently (p = 0.038). The mean salivary pH was 6.9, while the mean buffer capacity was 5.8. Female respondents have a statistically lower buffer capacity (5.8 ± 0.5) than male respondents (6.1 ± 0.4) (p = 0.047). Conclusions: Dentistry students are introduced to good oral hygiene habits, especially female students, while dietary habits should be improved. However, one in eight dental students is at high caries risk. By assessing the level of caries experience, targeted strategies can be developed to promote, maintain, and enhance oral health among dental students.

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.

Identifying sources of variation in added sugar intake for Alaska Native children using a hair biomarker

Sugars from sugar-sweetened beverages (SSBs) are an important risk factor for tooth decay. The study goal was to determine if there was variation in added sugar intake across communities and between and within households. In this cross-sectional study, intakes of total sugar, added sugar, and sugar-sweetened beverages (SSBs) were estimated for 282 Alaska Native children ages 0-10 years from 131 households in three Yukon-Kuskokwim (YK) Delta communities using biomarker equations based on hair carbon and nitrogen isotope ratios previously developed for the Yup'ik population. ANOVA was used to assess associations between each predictor (community and household) and outcome (estimated total sugars, added sugars, and SSB intake). Between- and within-household variation was estimated using a linear mixed-effects model with a random intercept for households with three or more children. There was no significant difference in mean estimated total sugar (p = 0.29), added sugar (p = 0.24), or SSB intake (p = 0.40) across communities. Significant variations were observed between and within households, with within-household variation amounting to 59% of the between-household variation. Added sugar intake in Alaska Native children from the three study communities is higher than the recommended maximum, and the variation is greater within households than between households.

Fluoride and gallein regulate polyphosphate accumulation in dental caries-associated Lacticaseibacillus

Inorganic polyphosphates (polyPs) are energy-storing biopolymers synthesized by all three domains of life. PolyP accumulation has been well studied with respect to its role in stress response, but its role in dental disease has received less attention. Dental decay can be promoted by changes in pH as well as the chemical activity of ions such as phosphate in oral fluids at the enamel interface. Previous work has shown that the drawdown of phosphate from biofilm fluids can alter the saturation state of oral fluids to thermodynamically favour mineral dissolution. The members of the Lactobacillaceae are known to accumulate polyP and play a role in early-stage and late-stage dental caries. In this study, we examined the effects of potential metabolic inhibitors on polyP accumulation in Lacticaseibacillus rhamnosus. We observed that two inhibitors of the enzyme responsible for polyP synthesis, gallein and fluoride, inhibited polyP accumulation in a balanced medium. However, fluoride and gallein treatments amended with either glucose or lactate were found to enhance polyP accumulation. These results illustrate the potential complexity of polyP metabolism in the oral environment.

Behavioral Correlates of Caregiver-Reported Oral Health of Children with Cleft Palate with or without Cleft Lip Ages 14 to 48 Months: An Observational Study

To identify behaviors associated with poor caregiver-reported oral health in a population of young children with cleft palate with or without cleft lip (CP ± L).

Observational cross-sectional study.

U.S. Cleft Outcomes Research NETwork (CORNET) Consortium.

Eight hundred thirty-four caregivers of US children with CP ± L ages 14 to 48 months who provided demographic and medical information and answered 8 items on oral health behaviors (eg, sugar-sweetened beverage intake frequency, having a regular source of dental care, toothbrushing, and fluoride exposure).

Caregiver-reported oral health status of the child (poor/fair vs good/very good). Logistic regression models were used to generate confounder-adjusted odds ratios (OR) and evaluate associations between oral health behaviors and caregiver-reported oral health status of the child.

The mean age of children was 25.5 ± 7.5 months, 82.7% were white, and 24.1% were Hispanic/Latino. About 16.7% of caregivers reported their child's oral health as fair/poor. Children consuming 2+ servings of juice and/or sugar-sweetened beverages daily (OR: 2.18; 95% confidence interval [CI]: 1.2, 4.0; P = 0.011), those drinking bottled water (OR: 1.75; 95% CI: 1.0, 3.1; P = 0.049), and those consuming 1+ servings of meal replacement drinks daily (OR: 2.86; 95% CI: 1.2, 6.5; P = 0.015) had increased odds of fair/poor caregiver-reported child oral health.

Sugar-sweetened beverages and meal replacement drinks, as well as bottled water intake, were associated with poorer caregiver-reported oral health for children with CP ± L. Future research should focus on ways to improve beverage-related behaviors in children with CP ± L to prevent dental diseases and promote oral health.

Socioeconomic vulnerability and access to community water fluoridation in Washington

BACKGROUND

The aim of the authors was to determine whether socioeconomic vulnerability is associated with community water fluoridation (CWF).

METHODS

The authors used US Census Bureau data to create 4 county-level vulnerability markers (percentages non-White, Hispanic or Latino, below the federal poverty threshold, education below high school), obtained county-level CWF data from the Washington State Department of Health, and evaluated associations using Spearman rank correlation coefficient and the Kruskal-Wallis rank sum test. The authors then interviewed 122 community members in Washington (December 2022-March 2023) and analyzed the interview data inductively.

RESULTS

A higher percentage of non-White people at the county level was associated with a significantly higher level of CWF (Spearman rank correlation coefficient, 0.55; 95% CI, 0.29 to 0.82; P < .001), whereas county-level poverty was associated with significantly lower CWF (Spearman rank correlation coefficient, -0.36; 95% CI, -0.70 to -0.03; P = .02). High school completion was not associated with county-level CWF. Significantly larger proportions of Hispanics and Latinos lived in counties with higher CWF (P < .05). From the interviews, more participants thought tap water was healthy than unhealthy, but 41% had mixed feelings. Similarly, more participants thought CWF was acceptable than unacceptable, with 35% reporting mixed feelings. Negative views about tap water and CWF were more common among non-White participants.

CONCLUSIONS

People in racially and ethnically diverse communities in Washington appear to have greater access to CWF, whereas those in lower-income communities have poorer access.

PRACTICAL IMPLICATIONS

CWF is an important population-level strategy to prevent caries. Additional work is needed to improve access to CWF, especially for people from low-income communities.

Examining the effects of brand and licensed characters on parents' perceptions of Children's breakfast cereals

Brand and licensed characters frequently appear on children's breakfast cereal boxes and are known to affect children's product perceptions, selection, and consumption. However, less is known about their impact on parents' perceptions of foods they purchase for their child. The present study assessed the impact of brand and licensed characters featured on three children's breakfast cereal packages on parents' intentions and perceptions in an online experiment. Parents of children aged 2-12 years (n = 1013) were randomized into one of two conditions: breakfast cereals containing brand and licensed characters or breakfast cereals without any characters. Within each condition, participants viewed three breakfast cereal brands in random order per their assigned condition and reported their purchase intentions, healthfulness perceptions, and perceptions of appeal to children using 5-point Likert scales. No significant differences in purchase intentions (p = 0.91), perceived healthfulness (p = 0.52) or perceived child appeal (p = 0.59) were observed between the experimental and control groups. However, exploratory moderation analyses revealed that educational attainment moderated the impact of experimental condition on purchase intentions (p for interaction = 0.002) such that participants with a bachelor's degree in the character condition reported 0.36 points lower purchase intentions compared to the control with no difference between conditions for those with an associate's degree/trade school or high school degree or less. This study did not find an impact of brand and licensed characters on children's breakfast cereals, suggesting that their primary appeal is directly to children. Parents with higher educational attainment may be skeptical of characters on cereal brands. Additional research on the impact of brand and licensed characters on other products, in real-world settings, is needed.

The carbon isotope ratio of breath is elevated by short-term and long-term added sugar and animal protein intake in a controlled feeding study

BACKGROUND

The breath carbon isotope ratio (CIR) was recently identified as a noninvasive candidate biomarker of short-term added sugars (AS) intake.

OBJECTIVES

This study aimed to better understand the potential of the breath CIR as a dietary biomarker. We evaluated the effects of short-term and long-term intakes of AS, animal protein (AP), and related variables on breath CIR, in the context of typical dietary intake patterns.

METHODS

We conducted a 15-d controlled feeding study of 100 adults (age 18-70 y, 55% females) in Phoenix, AZ. Participants were provided individualized diets that approximated habitual food intakes and recorded the timing of food consumption. Three breath samples (fasting, midday, and evening) were collected on each of 3 nonconsecutive study days. We modeled the effects of dietary intake in each of 8 h preceding collection of the breath sample on breath CIR with a linear mixed model, which also included 15-d mean intakes, sex, age, and BMI.

RESULTS

Median (IQR) intakes of AS and AP in our study were 65 (38) and 67 (33) g/d, respectively. Midday and evening breath CIRs correlated strongly with each other (0.80) and with fasting breath CIR (0.77 and 0.68, respectively). In our linear mixed models, breath CIR increased by AS consumed 1-4 h before sample collection, AP consumed 3-6 h before sample collection, and 15-d intakes of AS and AP, all with similar effect sizes. The breath CIR was also inversely associated with 15-d intakes of intrinsic sugars and plant protein; thus, associations with 15-d intakes were particularly strong when expressed proportionally as the AS ratio (added sugars/total sugars) and AP ratio (animal protein/total protein).

CONCLUSIONS

The breath CIR is a promising measure of long-term intakes of AS and AP, especially as proportional intakes. Approaches to increase specificity would benefit the further development of this biomarker.

Health-risk behaviours co-occur among children with untreated caries

OBJECTIVES

The aim of this study was to examine whether an aggregate of health risk behaviours is associated with the number of untreated dental caries among 12- and 15-year-old children in England, Wales and Northern Ireland.

MATERIALS AND METHODS

Data were from the Children's Dental Health Survey (CDHS) 2013, a nationally representative sample of England, Wales and Northern Ireland. The survey included assessment of oral health and data on socioeconomic, demographic and behavioural factors pertaining to children aged 12-15 years. Tooth condition (decayed, missing and filled) was assessed by NHS dentists. The survey included questions on age, sex, country, index of multiple deprivation, smoking, alcohol consumption, frequent sugar consumption and sweetened sodas, infrequent dental visit, infrequent toothbrushing and infrequent consumption of fresh fruits. Health risk behaviours were summed up to create an aggregate variable of health risk behaviour. The association between number of untreated caries and the aggregate of health risk behaviours was assessed using negative binomial regression and adjusting for age, sex, country and deprivation.

RESULTS

The total number of children included in the analysis was 4414. The mean number of untreated caries was generally higher among children with health risk behaviours. The aggregate of risk behaviour was associated with greater prevalence of untreated dental caries with rate ratio (RR) 1.26 (95% confidence interval: 1.18, 1.36).

CONCLUSION

This study demonstrated an association between an aggregate of health risk behaviours and untreated caries. The findings highlight the importance of addressing multiple risk factors not only those directly related to dental caries.

Cross-sectional study of association between caries and fluoridated water among third-grade students in Pennsylvania

BACKGROUND

Caries is the most common chronic disease among children. In Pennsylvania, a comprehensive oral health Basic Screening Survey and assessment of the association between caries and community water fluoridation (CWF) among children have not been conducted.

METHODS

From 2021 through 2022, the first Basic Screening Survey was conducted among third-grade students in Pennsylvania. Oral health and demographic data were collected. CWF data were provided by the Pennsylvania Department of Environmental Protection. The relative risk of developing caries in association with CWF was assessed using the GENMOD procedure in SAS, Version 9.4 (SAS Institute) in this cross-sectional study.

RESULTS

Caries prevalence was 59.7% among 4,120 screened students. Participation in the free or reduced lunch program and CWF were each significantly associated with risk of developing caries after adjustment for age, sex, and race and ethnicity. The risk of developing caries was 33% higher among students who participated in the free or reduced lunch program than those who did not participate (relative risk, 1.33; 95% CI, 1.24 to 1.42). Students with the highest CWF coverage had a nearly 16% lower risk of developing caries than those without CWF coverage (relative risk, 0.84; 95% CI, 0.75 to 0.94).

CONCLUSIONS

CWF was significantly associated with a reduced risk of developing caries. Efforts are needed to increase CWF coverage, along with promotion of oral health education and healthy dietary habits among Pennsylvania children.

PRACTICAL IMPLICATIONS

Increasing CWF coverage will reduce caries burden among Pennsylvania children. Although Pennsylvania has no state laws to regulate CWF, these findings are persuasive for local municipalities to consider expanding CWF coverage.

Associations of activity, sedentary and sleep behaviors with oral health indictors in children and adolescents: a cross-sectional analysis

BACKGROUND

The purpose of this study was to examine the associations of physical activity (PA), recreational screen time, and sleep with indicators of poor oral health in youth.

METHODS

Participants were children and adolescents whose parents completed the 2022 National Survey of Children's Health (N = 34,342; 49% female; Mean age = 11.9 +/- 3.5 years). The dependent variables were three binary response items that indicated the presence of toothaches, bleeding gums, and cavities within the previous 12 months. Independent variables were three items indicating the weekly frequency of 60 min of PA, hours of recreational screen time, and hours of weeknight sleep. Relationships between variables were examined using double-selection logistic regression with demographic, dietary, oral hygiene, and dental service covariates selected using the plug-in method of the least absolute shrinkage and selection operator.

RESULTS

Compared to zero days of PA, 4-6 days of PA per week was associated with 30% lower odds of bleeding gums (p = 0.021). Compared to less than 1 h of recreational screen time, 2 h or more hours of recreational screen time were associated with a 1.26 to 1.62 times higher odds of cavities (p < 0.01). Compared to 5 h or less of sleep, 7 to 10 h of sleep was associated with 47-61% lower odds of bleeding gums and 31-47% lower odds of cavities (p < 0.01). Secondary analyses indicated that at least 2 of the movement behavior recommendations had to have been adhered to for positive associations with indicators of oral health to be observed. For toothaches, bleeding gums, and cavities, meeting 2 or 3 recommendations was associated with lower odds of poor oral health; whereas adhering to only one recommendation was not.

CONCLUSION

Children with higher PA and sleep durations had improved oral health indicators and children with longer periods of screen time exposure had poorer oral health indicators. Our findings recommend adhering to multiple movement behavior recommendations to achieve improvements in oral health indicators.

Sugar substitutes on caries prevention in permanent teeth among children and adolescents: a systematic review and meta-analysis

OBJECTIVES

This study aimed to systematically review the effect of sugar substitute consumption on caries prevention in permanent teeth among children and adolescents.

DATA

Randomized controlled trials (RCTs) and controlled clinical trials (CCTs) comparing the clinical effect of sugar substitutes (both high- and low-intensity sweeteners) in preventing caries in permanent teeth among children and adolescents aged 6-19 were included.

SOURCES

A systematic search was conducted in three databases (PubMed, Web of Science and Embase) without any restrictions on publication year.

STUDY SELECTION

The initial search found 1,859 items, and finally, 15 studies (11 RCTs and 4 CCTs) with a total of 6325 participants (age: 6-18 years) were included. The Cochrane risk-of-bias assessment tools were used for quality assessment. Most (80%, 12/15) were graded as having a 'moderate' or 'high' risk of bias. All trials investigated sugar alcohol, which is a low-intensity sweetener. Xylitol was the most commonly investigated (73.3%, 11/15), followed by sorbitol (46.7%, 7/15), and erythritol (13.3%, 2/15). Results of the meta-analysis showed that both xylitol (standardized mean difference [SMD]: -0.50, 95% confidence interval [CI] -0.85 to -0.16, P = 0.005) and sorbitol (SMD: -0.10, 95% CI: -0.19 to -0.01, P = 0.03) had a significant effect in preventing dental caries compared to no treatment/placebo. No clinical trials on high-intensity sweeteners such as aspartame and saccharin were found.

CONCLUSION

The consumption of xylitol or sorbitol is potentially effective in preventing caries in permanent teeth among children and adolescents. No clinical evidence is available regarding the role of high-intensity sweeteners in caries prevention.

CLINICAL SIGNIFICANCE

The use of xylitol or sorbitol as sugar substitutes has a beneficial effect in preventing dental caries among children and adolescents.

Assessment of Water Intake among Chinese Toddlers: The Report of a Survey

Toddlerhood (aged 13~36 months) is a period of dietary transition, with water intake being significantly influenced by parental feeding patterns, cultural traditions, and the availability of beverages and food. Nevertheless, given the lack of applicable data, it is challenging to guide and evaluate the water intake of toddlers in China. In this study, our objectives were to assess the daily total water intake (TWI), evaluate the consumption patterns of various beverages and food sources contributing to the TWI, determine the conformity of participants to the adequate intake (AI) recommendation of water released by the Chinese Nutrition Society, and analyze the various contributors to the daily total energy intake (TEI). The data for the assessment of water and dietary intake were obtained from the cross-sectional dietary intake survey of infants and young children (DSIYC, 2018-2019). A total of 1360 eligible toddlers were recruited in the analysis. The differences in related variables between two age groups were compared by Mann-Whitney U test and Chi-Square test. The potential correlation between water and energy intake was examined utilizing age-adjusted partial correlation. Toddlers consumed a median daily TWI of 1079 mL, with 670 mL (62.3%, r = 0.752) derived from beverages and 393 mL (37.7%, r = 0.716) from foods. Plain water was the primary beverage source, contributing 300 mL (52.2%, r = 0.823), followed by milk and milk derivatives (MMDs) at 291 mL (45.6%, r = 0.595). Notably, only 28.4% of toddlers managed to reach the recommended AI value. Among these, toddlers obtain more water from beverages than from foods. The median daily TEI of toddlers was 762 kcal, including 272 kcal from beverages (36.4%, r = 0.534) and 492 kcal from foods (63.6%, r = 0.894). Among these, the median daily energy intake from MMDs was 260 kcal, making up 94.6% of the energy intake from beverages (r = 0.959). As the pioneer survey on TWI of toddlers in China based on nationally representative data, attention to the quality and quantity of water intake and actions to better guide parents by both individuals and authorities are eagerly anticipated. Additionally, the revision of the reference value of TWI for Chinese toddlers is urgently required.

Factors associated with the impact of fixed appliance orthodontic treatment on the oral health-related quality of life of adolescents: Assessment using a condition-specific instrument

Background

Oral outcomes may have an impact on quality of life. The aim of this study was to assess factors associated with the impact of fixed appliance orthodontic treatment on the oral health-related quality of life (OHRQoL) of adolescents.

Material and Methods

Individuals aged 10 to 18 years undergoing orthodontic treatment were included. Data regarding adolescents' sex and age, parental schooling, family income, and number of individuals who depend on income were collected. Clinical variables, orthodontic tooth extraction and malocclusion severity were also analyzed. OHRQoL was assessed with a questionnaire with items distributed across nine domains: aesthetics, functional limitation, diet, hygiene, maintenance, physical impact, social impact, time constraints, and transport/cost inconveniences. The higher the score, the more negative the adolescent's perception of his/her OHRQoL. Statistical analysis was performed.

Results

Seventy-five adolescents participated. Individuals aged ≤12 years had a more negative perception of the diet domain (p=0.026). Individuals whose parents/guardians had ≥8 years of schooling had a more negative perception of the impact on the hygiene domain (p<0.024). Individuals whose families had an income of ≤2 salaries had a more negative perception of the maintenance domain (p=0.016). Girls had a more negative perception of the physical impact domain (p<0.018). Girls (p=0.011), adolescents whose families had an income of ≤2 salaries (p=0.003), and adolescents who had severe malocclusion (p=0.026) had a more negative perception of the transport/cost inconveniences domain. Girls had a significantly higher overall score in response to the questionnaire than boys (p=0.041).

Conclusions

Adolescents' sex, age, and malocclusion as well as parental education and family income were associated with the impact of orthodontic treatment on adolescents' OHRQoL. Key words:Adolescent, Quality of life, Orthodontic treatment, Fixed appliance.

Sleep disorders, anxiety and obesity associated with untreated dental caries in children eight to ten years of age

OBJECTIVE

To evaluate the presence of sleep disorders, obesity and anxiety associated with cavitated carious lesions in children aged 8 to 10 years.

MATERIALS AND METHODS

A cross-sectional study was carried out in the Northeast of Brazil. The sample was comprised of 793 schoolchildren randomly selected from public and private schools. Calibrated examiners (Kappa >0.80) performed the clinical examination of dental caries using the International Caries Detection and Assessment System and applied the Revised Children's Manifest Anxiety Scale and the Sleep Disturbance Scale for Children questionnaires. The anthropometric variables evaluated were weight and height. Negative binomial regressions (α ≤ 0.05) were performed. A Directed Acyclic Graph was prepared using DAGitty software (version 3.0), to select the co-variables for the statistical fits.

RESULTS

The prevalence of tooth decay was 52.8%. The mean number of tooth surfaces with cavitated caries was 2.2(2.8), 58.9% of the schoolchildren had some type of sleep disorder, while 20.2% were anxious and 29.1% were obese. Sleep disturbance (RR = 1.38; 95% CI: 1.05-1.83), general anxiety (RR = 1.71; 95% CI: 1.32-2.21), obesity (RR = 1.48; 95% CI: 1.17-1.86) were associated with dental caries in the final model.

CONCLUSION

The presence of carious lesions was higher in children with sleep disorders, anxiety, obesity, and those who experienced dry mouth.

Probabilistic graphical modelling of early childhood caries development

In order to develop a statistical model for complex interactions among factors affecting early childhood caries development (ECC), 234 children from the "XXXX oral growth longitudinal study" were analysed at ages 3, 4 and 5. A questionnaire for children's parents (clinical history, nutritional and oral hygiene habits) and clinical oral examinations were recorded each year. The probabilistic dependence structure on the most significant factors was modelled with an Undirected Graphical Model (UGM or Markov random fields) which provides a probabilistic reasoning approach for the establishment of multi-way associations. The best fitting UGM was estimated through the maximum likelihood principle and two-way factor associations were verified through Fisher's exact statistical hypothesis tests for count data. The effect of sugar intake on caries incidence is mediated by oral hygiene; for caries incidence, oral hygiene quality is more relevant than toothbrushing time; the effect of pacifier on caries incidence is statistically significant only when considered in combination with breastfeeding time. Among behavioural ECC risk factors, the quality of oral hygiene, and not the toothbrushing frequency, is a primary factor that modulates the sugar intake in his primary role of the ECC developer. School-based oral health programs for ECC prevention should be improved with supervised toothbrushing program. UGM analysis could improve the school-based oral health programs with more effective and efficient prevention strategies based on the hierarchical interactions among the ECC risk factors. Oral hygiene plays a pivotal role in early childhood caries and can modulate positively or negatively their development. Supervised toothbrushing is a crucial intervention to be included in the daily educational and clinical practice and in the school-based oral health promotion programs.

Development and Testing of the Novel Sugar Meter for Informing Sugar Intake Guidelines to Parents of Three- to Six-Year-Old Children: A Cross-Sectional Study

INTRODUCTION

In recent years, the consumption of refined sugar has increased manifold. Added sugar is implicated in dental caries, cardiovascular risk and obesity amongst other conditions. The 1025 World Health Organization (WHO) Sugar Guidelines recommends sugar intake below 10% of energy, but there is limited awareness about the same in the general population. The aim of this study was to test the Novel Sugar Meter for informing the WHO Sugar Guidelines to the parents of three- to six-year-old children.

METHODS

Twenty consenting parents and their three- to six-year-old children from an English-medium school in Navi Mumbai, India, were selected. The parents were asked to record their child's baseline dietary data for three consecutive days including one weekend day. The Novel Sugar Meter, an indigenously developed ready reckoner for identifying the quantity of sugars consumed, was used. The parents were counselled using the Novel Sugar Meter (intervention) and standard instructions on the WHO guidelines (control). The dietary data were recorded again to assess and compare dietary behaviour modifications.

RESULTS

Comparison of pre-intervention versus post-intervention sugar consumptions showed a statistically significant reduction in the Novel Sugar Meter group (t(10) = 3.70891; p = .001388) but not in the control group (t(10) = 0.94081, p = 0.35926). Both groups showed a reduction in the frequency of daily sugar exposure, with significantly more reduction in the Novel Sugar Meter group (p = .000049).

CONCLUSION

Novel Sugar Meter-based counselling has the potential for application for reducing the quantity and frequency of sugar consumption in children.

Pairwise approach for analysis and reporting of child's free sugars intake from a birth cohort study

OBJECTIVES

The prospective cohort design is an important research design, but a common challenge is missing data. The purpose of this study is to compare three approaches to managing missing data, the pairwise (n = 1386 children), the partial or modified pairwise (n = 1019) and the listwise (n = 546), to characterize the trajectories of children's free sugars intake (FSI) across early childhood.

METHODS

By applying the Group-based Trajectory Model Technique to three waves of data collected from a prospective cohort study of South Australian children, this study examined the three approaches in managing missing data to validate and discuss children's FSI trajectories.

RESULTS

Each approach identified three distinct trajectories of child's FSI from 1 to 5 years of age: (1) 'low and fast increasing', (2) 'moderate and increasing' and (3) 'high and increasing'. The trajectory memberships were consistent across the three approaches, and were for the pairwise scenario (1) 15.1%, (2) 68.3% and (3) 16.6%; the partial or modified pairwise (1) 15.9%, (2) 64.1% and (3) 20.0%; and the listwise (1) 14.9%, (2) 64.9% and (3) 20.2% of children.

CONCLUSIONS

Given the comparability of the findings across the analytical approaches and the samples' characteristics between baseline and across different data collection waves, it is recommended that the pairwise approach be used in future analyses to optimize the sample size and statistical power when examining the relationship between FSI in the first years of life and health outcome such as dental caries.

Sugar-sweetened beverage intake and convenience store shopping as mediators of the food insecurity-Tooth decay relationship among low-income children in Washington state

INTRODUCTION

There are oral health disparities in the U.S. and children in food-insecure households have a higher burden of tooth decay. Identifying the mechanisms underlying the food insecurity-tooth decay relationship could inform public health interventions. This study examined how sugar-sweetened beverage (SSB) intake and frequent convenience store shopping mediated the food insecurity-tooth decay relationship for lower-income children.

MATERIALS AND METHODS

Cross-sectional study data included a household survey, beverage questionnaire, and dental examination. The sample included 452 lower-income, racially-diverse, child-caregiver dyads in 2018 from King County in Washington state. The exposure was household food insecurity, the outcome was untreated decayed tooth surfaces, and the proposed mediators were SSB intake and frequent convenience store shopping (≥2 times/week). Causal mediation analyses via the potential outcomes framework was used to estimate natural indirect and direct effects.

RESULTS

Fifty-five percent of participants were in food-insecure households, the mean number of decayed tooth surfaces among children was 0.87 (standard deviation [SD] = 1.99), the mean SSB intake was 17 fluid ounces (fl/oz)/day (SD = 35), and 18% of households frequently shopped at a convenience store. After adjusting for confounders, household food insecurity and log-transformed SSB intake (fluid ounces/day) were positively associated with decayed tooth surfaces, but not at the a α = 0.05 level (mean ratio [MR] 1.60; 95% confidence interval [CI] 0.89, 2.88; p = .12 and MR 1.16; 95% CI 0.93, 1.46; p = .19, respectively). Frequent convenience store shopping was associated with 2.75 times more decayed tooth surfaces (95% CI 1.61, 4.67; p < .001). SSB intake mediated 10% of the food insecurity-tooth decay relationship (p = .35) and frequent convenience store shopping mediated 22% (p = .33).

CONCLUSIONS

Interventions aimed at addressing oral health disparities in children in food-insecure households could potentially focus on reducing intake of SSBs and improving access to healthful foods in lower-income communities.

Cariogenic diet consumption during lockdown

BACKGROUND

During stressful situations such as pandemic-associated lockdowns, individuals' diets may change towards (cariogenic) 'comfort food'. This study assessed the dietary patterns during the lockdown in the Colombian population.

METHODS

A cross-sectional online survey was designed. A convenience sample of 489 adults was drawn, with 50% of them being in COVID-19 lockdown and the other being not or only partially in lockdown. The questionnaire collected data about the type and frequency of food consumed, with a special focus on cariogenic (i.e., rich in free sugars and starches) food. Descriptive analyses were performed, and a generalised linear model was estimated to predict the frequency of cariogenic diet consumption in this period of time.

RESULTS

Sweet whole wheat bread (38.2%, p = 0.005), flavoured milk (26.4%, p = 0.002), sugar-sweetened bubble gums (39.8%, p = 0.001), toffees (35.4%, p = 0.004), soft candies (e.g., gums) (35.4%, p = 0.018), chocolates (55.3%, p = 0.017), filled doughnuts (28.5%, p = 0.013) or grapes (51.2%, p = 0.002) were significantly consumed more during the lockdown. Multivariable generalised linear modelling showed being single, having children and being in lockdown were significantly associated with higher frequency of cariogenic food consumption.

CONCLUSIONS

Lockdown was found to be associated with detrimentally altered food consumption patterns and, specifically, a more cariogenic diet. Healthcare professionals should consider this when reopening services, and political decision-makers may want to reflect on the unwarranted side effect of lockdown.

Children's reaction to sugar reduced dairy desserts in the context of the implementation of nutritional warning labels: An exploratory study

The aim of the present work was to explore children's reaction to sugar reduction in the context of the implementation of nutritional warnings in Uruguay. The study was composed of two sessions involving three evaluation conditions: tasting without package information, package evaluation without tasting, and tasting with package information. A total of 122 children, ages ranging between 6 and 13 years old (47% girls) were involved in the study. In the first session, children's hedonic and emotional response to a regular and a sugar-reduced chocolate dairy dessert (without other sweeteners) was evaluated. In the second session, children first evaluated their expected liking, emotional associations and choice of packages differing in the presence of warning labels for excessive sugar content and cartoon character (2x2 design). Finally, they tasted the selected sample in the presence of the package and evaluated their liking, emotional associations, and intention to re-taste it. Although sugar reduction led to a significant reduction in overall liking, the dessert with 40% sugar reduction showed a mean overall score of 6.5 in a 9-point hedonic scale and was described using positive emoji (, , ). When the desserts were tasted with package information, no significant differences in the expected overall liking of the regular and sugar-reduced dessert were found. Regarding the effect of packaging elements, the presence of a warning label highlighting excessive content of sugar did not have a significant effect on children's choice. Instead, children's choices were defined by the presence of a cartoon character. Results from the present work provide additional evidence about the feasibility of reducing the sugar content and sweetness of dairy products targeted at children and stress the need to regulate the use of cartoon characters on products with an unfavorable nutritional profile. Methodological recommendations for sensory and consumer research with children are also discussed.

Changes in Dental Outcomes After Implementation of the Philadelphia Beverage Tax

INTRODUCTION

Beverage taxes are associated with declines in sugar-sweetened beverage sales and consumption, but few studies have evaluated the associations of these taxes with health outcomes. This study analyzed changes in dental decay after the implementation of the Philadelphia sweetened beverage tax.

METHODS

Electronic dental record data were obtained on 83,260 patients living in Philadelphia and control areas from 2014 to 2019. Difference-in-differences analyses compared the number of new Decayed, Missing, and Filled Teeth with that of new Decayed, Missing, and Filled Surfaces before (January 2014-December 2016) and after (January 2019-December 2019) tax implementation in Philadelphia and control patients. Analyses were conducted in older children/adults (aged ≥15 years) and younger children (aged <15 years). Subgroup analyses stratified by Medicaid status. Analyses were conducted in 2022.

RESULTS

The number of new Decayed, Missing, and Filled Teeth did not change after tax implementation in Philadelphia in panel analyses of older children/adults (difference-in-differences= -0.02, 95% CI= -0.08, 0.03) or younger children (difference-in-differences=0.07, 95% CI= -0.08, 0.23). There were similarly no post-tax changes in the number of new Decayed, Missing, and Filled Surfaces. However, in cross-sectional samples of patients on Medicaid, the number of new Decayed, Missing, and Filled Teeth was lower after tax implementation in older children/adults (difference-in-differences= -0.18, 95% CI= -0.34, -0.03; -22% decline) and younger children (difference-in-differences= -0.22, 95% CI= -0.46, 0.01; -30% decline), with similar results for number of new Decayed, Missing, and Filled Surfaces.

CONCLUSIONS

The Philadelphia beverage tax was not associated with reduced tooth decay in the general population, but it was associated with reduced tooth decay in adults and children on Medicaid, suggesting potential health benefits for low-income populations.

To Assess the Prevalence of Dental Caries and Its Association with Body Mass Index, Socioeconomic Status, Dietary Habits, and Oral Hygiene among 6-12-year-old Children in Faridabad

Aim

The aim of our study was to assess the prevalence of dental caries and the body mass index (BMI) in included school-going children. Moreover, to examine the relationship between the prevalence of dental caries, BMI, and socioeconomic (SES) status and to evaluate sugar consumption and other dietary habits as risk factors for dental caries.

Materials and methods

The present cross-sectional study was performed among 400 school-going children aged 6-12 years from Faridabad city, Haryana. Parents filled out questionnaires for their respective children. The clinical examination of dental caries was performed according to World Health Organization (WHO) 1997. The BMI calculation was done by measuring height and weight.

Statistical analysis

The collected data were analyzed statistically using parametric and nonparametric tests.

Results

The prevalence of dental caries in deciduous teeth was 95.5% and in permanent teeth was 47.3%, respectively.

Conclusion

This study displayed the positive correlation of dental caries to BMI, oral hygiene practices, beverages, aerated drinks, chips, candy, and tea/coffee. Whereas the SES status and dietary habits Jam group variable had no significance in relation to dental caries.

Meeting the Healthy People 2030 Added Sugars Target

INTRODUCTION

Many Americans exceed the dietary recommendations for added sugars. Healthy People 2030 set a population target mean of 11.5% calories from added sugars for persons aged ≥2 years. This paper describes the reductions needed in population groups with varying added sugars intake to meet this target using four different public health approaches.

METHODS

Data from the 2015-2018 National Health and Nutrition Examination Survey (n=15,038) and the National Cancer Institute method were used to estimate the usual percentage calories from added sugars. Four approaches investigated lowering intake among (1) the general U.S. population, (2) people exceeding the 2020-2025 Dietary Guidelines for Americans recommendation for added sugars (≥10% calories/day), (3) high consumers of added sugars (≥15% calories/day), or (4) people exceeding the Dietary Guidelines for Americans recommendation for added sugars with two different reductions on the basis of added sugars intake. Added sugars intake was examined before and after reduction by sociodemographic characteristics.

RESULTS

To meet the Healthy People 2030 target using the 4 approaches, added sugars intake needs to decrease by an average of (1) 13.7 calories/day for the general population; (2) 22.0 calories/day for people exceeding the Dietary Guidelines for Americans recommendation; (3) 56.6 calories/day for high consumers; or (4) 13.9 and 32.3 calories/day for people consuming 10 to <15% and ≥15% calories from added sugars, respectively. Differences in added sugars intake were observed before and after reduction by race/ethnicity, age, and income.

CONCLUSIONS

The Healthy People 2030 added sugars target is achievable with modest reductions in added sugars intake, ranging from 14 to 57 calories/day depending on the approach.

High unhealthy food and beverage consumption is associated with poor diet quality among 12-35-month-olds in Guédiawaye Department, Senegal

Background

High consumption of unhealthy foods and beverages (UFB) during early childhood is cause for concern, with growing evidence from low- and middle-income countries finding associations with poor diet quality and malnutrition. Research from sub-Saharan Africa remains limited, with no studies quantifying the contribution of UFB to total energy intakes among young children or exploring the relationship between such intakes and diet quality or anthropometric outcomes.

Objectives

Assess UFB consumption patterns and their contribution to total energy intake from non-breastmilk foods/beverages (TEI-NBF), assess the association between high UFB consumption and dietary/nutrition outcomes, and explore drivers of unhealthy food choice among young children in Guédiawaye Department, Senegal.

Methods

We conducted a cross-sectional study of a representative sample of 724 primary caregivers and their 12-35.9-month-old children. The study included a questionnaire, a quantitative four-pass 24-h dietary recall, and anthropometric measurements. The contribution of UFB to TEI-NBF was calculated and terciles generated. Logistic and linear models were used to compare outcomes of high versus low UFB consumption terciles.

Results

UFB contributed on average 22.2% of TEI-NBF, averaging 5.9% for the lowest tercile and 39.9% for the highest. Diets of high UFB consumers, as compared to low, were significantly less dense in protein, fiber, and seven of the 11 micronutrients assessed and significantly denser in total fat, saturated fat, and total sugar. No associations were found with anthropometric outcomes. High UFB consumers were older and more likely to be living in food insecurity. The most common drivers of commercial UFB consumption were related to child preference, the use of these products as behavior management tools, treats, or gifts, and the sharing of these products by someone else eating them.

Conclusion

High UFB consumption is associated with poor diet quality among 12-35-month-olds in Guédiawaye Department, Senegal. Addressing high UFB consumption during this critical developmental period should be prioritized in young child nutrition research, programming, and policy development.

Symbiotic relationship between Prevotella denticola and Streptococcus mutans enhances virulence of plaque biofilms

OBJECTIVES

This study aimed to explore that whether interactions between Prevotella denticola and Streptococcus mutans could promote the establishment of hypervirulent biofilms on teeth surface and eventually influence the occurrence and development of caries.

DESIGN

Based on single-species biofilms of either P. denticola or S. mutans, and dual-species biofilms of both bacteria, we compared the virulence properties associated with cariogenicity in vitro, including carbohydrate metabolism and acid productivity, synthesis of extracellular polysaccharides, biomass and architecture of biofilms, level of enamel demineralization and expression of virulence genes associated with carbohydrate metabolism and adhesion in S. mutans.

RESULTS

The data demonstrated that, compared to single-species of above two taxa, dual-species produced lactate by metabolizing carbohydrates at a higher level during the observation period. Moreover, dual-species biofilms accrued more biomass and exhibited more dense microcolonies and abundant extracellular matrix. And it's noticeable that the level of enamel demineralization in dual-species biofilms was more augmented than that of single-species. In addition, the presence of P. denticola induced the expression of virulence genes gtfs and gbpB in S. mutans.

CONCLUSIONS

Symbiotic relationship between P. denticola and S. mutans enhances caries-associated virulence of plaque biofilms, which might provide new strategies for effective prevention and treatment of caries.

Associations of PART1 and DEFB1 polymorphisms with Dental Caries in twelve-year-old children in Southern China: a cross-sectional study

OBJECTIVE

The aim of this study was to assess associations of PART1 rs27565 and DEFB1 rs11362 polymorphisms with the prevalence of dental caries in twelve-year-old children in Nandan County, Guangxi, China.

METHODS

A total of 1,061 children were included in this cross-sectional study and divided into two groups based on the Decayed, Missing and Filled teeth (DMFT) index: caries-free children (DMFT score = 0) and children with caries (DMFT score ≥ 1). Demographic characteristics, oral hygiene behaviour and dietary habits were collected through household records and questionnaires. Genomic DNA was extracted from buccal cells, and PART1 rs27565 and DEFB1 rs11362 polymorphisms were genotyped using a custom-designed 48-Plex single nucleotide polymorphism-scan kit.

RESULTS

Carriers of the PART1 rs27565 C allele (odds ratio [OR] = 1.338, 95% confidence interval (CI) = 1.015-1.764, P value = 0.039) and carriers of the DEFB1 rs11362 T allele (OR = 1.364, 95% CI = 1.056-1.762, P value = 0.017) had a higher risk of caries. Carriers of the PART1 rs27565 TC or CC genotype who ate sugary food more than once a week had a 1.6-fold higher risk of caries than TT carriers who ate sugary food at most once a week (OR = 1.579, 95% CI = 1.032-2.414, P value = 0.035). Carriers of the DEFB1 rs11362 CT or TT genotype who ate sugary food more than once a week had a 2.1-fold higher risk of caries than CC carriers who ate sugary food at most once a week (OR = 2.057, 95% CI = 1.438-2.940, P value < 0.001).

CONCLUSION

PART1 rs27565 and DEFB1 rs11362 polymorphisms were associated with caries in 12-year-old children in Nandan County, Guangxi, China. Carriers of the PART1 rs27565 TC or CC genotype and the DEFB1 rs11362 CT or TT genotype who ate sugary food more than once a week had a high probability of having caries.

Maintaining and Improving the Oral Health of Young Children

Oral health is an integral part of the overall health of children. Dental caries is a common and chronic disease process with significant short- and long-term consequences. The prevalence of dental caries remains greater than 40% among children 2 to 19 years of age. Although dental visits have increased in all age, race, and geographic categories in the United States, disparities continue to exist, and a significant portion of children have difficulty accessing dental care. As health care professionals responsible for the overall health of children, pediatricians frequently confront morbidity associated with dental caries. Because the youngest children visit the pediatrician more often than they visit the dentist, it is important that pediatricians be knowledgeable about the disease process of dental caries, prevention of disease, interventions to maintain and restore health, and the social determinants of children's oral health.

A conceptual model on caregivers' hesitancy of topical fluoride for their children

BACKGROUND

Topical fluoride hesitancy is a well-documented and growing public health problem. Despite extensive evidence that topical fluoride is safe and prevents tooth decay, an increasing number of caregivers are hesitant about their children receiving topical fluoride, leading to challenges in clinical settings where caregivers refuse preventive care.

PURPOSE

To explore the determinants of topical fluoride hesitancy for caregivers with dependent children.

METHODS

In this qualitative study, we interviewed 56 fluoride-hesitant caregivers to develop an inductive conceptual model of reasons why caregivers are hesitant.

RESULTS

The core construct of the conceptual model of topical fluoride hesitancy centered on caregivers "wanting to protect and not mess up their child". Six domains comprised this core construct: thinking topical fluoride is unnecessary, wanting to keep chemicals out of my child's body, thinking fluoride is harmful, thinking there is too much uncertainty about fluoride, feeling pressured to get topical fluoride, and feeling fluoride should be a choice.

CONCLUSIONS

Topical fluoride hesitancy is complex and multifactorial. Study findings provide insight for future efforts to understand and optimize caregivers' preventive care decision making.

Sorry Parents, Children Consume High Amounts of Candy before and after a Meal: Within-Person Comparisons of Children's Candy Intake and Associations with Temperament and Appetite

Candy provides little nutritional value and contributes to children's energy intake from added sugars. Factors influencing children's candy intake remain largely unknown. This study describes children's total candy intake (kcal) before and after a meal and examines associations of candy intake in both conditions with children's temperament and appetite among a predominantly White, highly educated sample. Children (n = 38, age 5-8 years) were given free access to 11 candies (5 chocolate, 6 non-chocolate) and non-food alternatives during a pre-meal and a post-meal condition. Parents completed the Child Behavior Questionnaire and the Child Eating Behavior Questionnaire. Total candy intake was less when offered after a meal (209.3 kcal; SD = 111.25) than before a meal when still hungry (283.6 kcal; SD = 167.3), but not statistically different. Individual differences in candy intake between conditions was calculated to categorize children into three groups: "Better Regulators" consumed more candy before a meal (39%), "Consistent/Poorer Regulators" consumed similar amounts before and after a meal regardless of hunger (32%), and "Most Disinhibited" children consumed more candy after a meal when not hungry (29%). The "Better Regulators" group was lowest in negative affect and the "Consistent/Poorer Regulators" group was highest in food responsiveness. Children's candy intake was high relative to daily energy needs both before and after a meal. Child negative affect and food responsiveness appear to be child characteristics that predispose children to poor self-regulation of candy intake before and after a meal.

Relation between caries experience and the consumption of sweetened drinks and processed food in children: A population-based study

OBJECTIVES

Diet can play a role in caries disease and the consumption of ultra-processed foods has increased over the years. The purpose was to propose predictive models on the relation between caries experience, diet, sex, and oral health aspects.

METHODS

This cross-sectional study included 5213 schoolchildren aged 2-11 years and a questionnaire based on WHO Oral Health Survey was applied to assess the intake of sugary foods, oral hygiene practices, access to health services and parents' perception; dmft/DMFT index, biofilm accumulation and orthodontic treatment need were assessed by 6 calibrated dentists.

RESULTS

The logistic model showed that female sex and presence of biofilm increased the chance of having early childhood caries; besides, this chance increased by 17% for each additional day of sweetened drink intake. In children aged 6-11 years, a negative binomial regression model showed that the absence of biofilm and frequency of toothbrushing were related to lower caries index, while male sex and the consumption of salty snacks and cake/cookies were related to higher dmft+DMFT index. Disagreement or weak agreement between caregivers' perception of the presence of dental caries and children's need for dental treatment was found.

CONCLUSION

Early childhood caries was dependent on the consumption of sweetened drinks and the presence of biofilm, while in older children the caries experience was predicted by the consumption of snacks, cakes and biscuits, biofilm accumulation and toothbrushing frequency, emphasizing the need of health education to encourage healthy eating habits and oral care with an approach to parents/caregivers to prevent dental caries development.

The Impact of the COVID-19 Lockdown on Sugar-Sweetened Beverage Consumption in Children in Saudi Arabia: A Mixed-Methods Study

(1) Background: In 2020, there seems to have been a global shift in lifestyle and eating habits with the emergence of the coronavirus disease 2019 (COVID-19) and the ensuing lockdowns implemented by national governments. This study assessed the impact of the COVID-19 lockdown on SSBs consumption among healthy 6-11 years old children in Saudi Arabia; (2) Methods: This is a mixed-methods study, incorporating a quantitative component, which was a validated Arabic online questionnaire completed by parents, and a qualitative component, involving structured interviews with 10 selected parents using a criterion sampling method; (3) Results: There was a small decrease in consumption reported during lockdown across all SSBs types (soft drinks, n = 58 (13.9%); juices: n = 115 (27.6%); flavored milk: n = 93 (22.3%)). The results showed that with every increase in the dental pain scale there was a positive odd (AOR:0.64; p = 0.001) of decreased consumption of SSBs. Several themes related to increase and decrease SSBs consumption emerged; (4) Conclusions: There was a small decrease in SSBs consumption during lockdown reported by parents. Several themes emerged that can be used to strategize against problematic eating behavior, enabling such provisions as family dietary interventions, which target both parents and children.

Knowledge, Attitude, and Behavior of Parents Regarding Early Childhood Caries Prevention of Preschool Children in Western Region of Saudi Arabia: A Cross-Sectional Study

The knowledge and beliefs of parents have an impact on their children's general and oral health. The objective of this study is to assess knowledge, attitude, and behavior of parents and identify possible associated factors of early childhood caries (ECC) in the western region of Saudi Arabia. Parents aged 18 and older were invited to complete a self-administered, validated questionnaire. Questions covered demographics, knowledge, attitude, and behavior regarding ECC etiology and prevention. Of the 644 parents who completed the questionnaire, 51.4% were not aware of the early signs of tooth decay, such as white lines. Pain and trauma were reported as the major reasons for a child to visit a dentist (42.4%). Only 37% of parents were aware of the importance of fissure sealant, and only 23% knew how it is applied. Compared with mothers, fathers were significantly less aware of hidden sugar and the relation between the frequency of consuming breast milk or bottled milk and caries development (p = 0.001). Similarly, fathers were more likely to believe that children could achieve effective teeth cleaning without parental assistance (p = 0.001). Preventive guidance should be provided by oral healthcare providers in Saudi Arabia to improve parents' knowledge of ECC prevention.

Lifestyle of Families with Children Aged 4-8 Years before and during Lockdown Due to COVID-19 Pandemic in Poland

The aim of the study was to evaluate the lifestyle changes of families with children aged 4-8 years during lockdown compared to the time before the COVID-19 pandemic. The study was conducted among 1098 parents during the first lockdown in Poland. An originally developed questionnaire was used as the research tool. The Wilcoxon test was used to determine the frequency of differences in the lifestyle of parents and children before the pandemic and during lockdown. Differences were found in the frequency of healthy habits in the periods under investigation, both in the lifestyle of parents and children. A moderately healthy lifestyle was predominant among families with children aged 4-8 years during lockdown. The families' lifestyle significantly changed in relation to the time before the pandemic. There is a need for lifestyle education for families with children to prevent the development of bad habits during and after the pandemic and isolation time.

Child-Directed Marketing, Health Claims, and Nutrients in Popular Beverages

INTRODUCTION

Fruit drinks are a major source of added sugar in children's diets. This study describes the associations between front-of-package child-directed marketing (i.e., sports, fantasy, or child-directed imagery; child-directed text) and (1) health-related claims and (2) nutrient content of fruit drinks, 100% juices, and flavored waters.

METHODS

Beverage purchase data from a national sample of 1,048 households with children aged 0-5 years were linked with front-of-package label and nutrition data to conduct a content analysis on fruit drinks (n=510), 100% juices (n=337), and noncarbonated flavored waters (n=40) in 2019-2020. Unstratified and stratified regression models assessed the differences in the prevalence of claims (macronutrient, micronutrient, natural/healthy, and fruit and juice), non-nutritive sweeteners, and nutrient content (calories, total sugar, and percent daily value of vitamin C) between drinks with and those without child-directed marketing in 2021.

RESULTS

Fruit drinks with child-directed marketing were more likely to show front-of-package micronutrient claims (OR=2.1, 95% CI=1.5, 3.1) and contained more vitamin C (18.5% daily value, 95% CI=1.6, 35.5) than fruit drinks without child-directed marketing. 100% juices with child-directed marketing contained less vitamin C (-35.6% daily value, 95% CI= -57.5, -13.8) and 3.0 (95% CI= -5.5, -0.4) fewer grams of sugar than 100% juices without child-directed marketing. Flavored waters with child-directed marketing contained less vitamin C (-37.9% daily value, 95% CI= -68.1, -7.6) than flavored waters without child-directed marketing.

CONCLUSIONS

The combination of child-directed marketing with health-related claims may mislead parents into believing that fruit drinks are healthy and appealing to their children, highlighting the need for government regulation of sugary drink marketing.

Decomposing consumer and producer effects on sugar from beverage purchases after a sugar-based tax on beverages in South Africa

Growing global concern about obesity and diet-related non-communicable diseases has raised interest in fiscal policy as a tool to reduce this disease burden and its social costs, especially excise taxes on sugar-sweetened beverages (SSBs). Of particular interest have been nutrient-based taxes to improve diet quality. These can incentivize producers to reformulate existing products and introduce healthier alternatives into their ranges. In 2018, South Africa adopted a sugar-based tax on SSBs, the Health Promotion Levy (HPL). Early findings suggest that purchases of higher-sugar taxable beverages fell and purchases of no- and lower-sugar beverages increased, alongside significant reductions in the sugar content of overall beverage purchases. However, underlying these changes are consumption shifts as well as product reformulation and changes in producers' product portfolios. Drawing on a household scanner dataset, this study employed a descriptive approach to decompose changes in the sugar content of households' non-alcoholic beverage purchases into producer factors (reformulation and product entry and exit) and consumer factors (product switching and volume changes as a result of price changes, changing preferences, or other factors). We look at these factors as the tax was announced and implemented across a sample of over 3000 South African households, and then by Living Standard Measures (LSM) groups (middle vs. high). The sugar content of beverage purchases fell by 4.9 g/capita/day overall, a 32% decrease. Taken in isolation, consumer switching and volume changes together led to a reduction equivalent to 71% of the total change, while reformulation accounted for a decrease equal to 34% of that change. Middle-LSM households experienced larger reductions than high-LSM households due to larger changes on the consumer side. For both LSM groups, reformulation-led reductions mostly occurred after implementation, and most changes came from taxable beverage purchases. As sugary drink tax designs evolve with broader implementation globally, understanding both supply- and demand-side factors will help to better assess the population and equity potential of these policies.

Infancy Dietary Patterns, Development, and Health: An Extensive Narrative Review

Correct dietary patterns are important for a child’s health from birth to adulthood. Understanding a child’s health as a state of entire physical, mental, and social well-being is essential. However, reaching adulthood in a complete health proper state is determined by feeding and dietary habits during preconception, pregnancy, or children infancy. Different factors, such as the mother’s lifestyle, culture, or socioeconomic status, are crucial during all these phases. In this review, we aimed to assess the long-term associations between infancy dietary patterns and health and their influence on development and growth. To reach this objective, a consensus critical review was carried out using primary sources such as scientific articles, and secondary bibliographic indexes, databases, and web pages. PubMed, SciELO, and Google Scholar were the tools used to complete this research. We found that high-income countries promote high-calorie foods and, consequently, obesity problems among children are rising. However, undernutrition is a global health issue concerning children in low- and middle-income countries; thus, parental socioeconomic status in early life is essential to children’s health and development, showing that biological, social, and environmental influences are increased risk factors for chronic diseases. This narrative review is aimed to collect evidence for early nutritional intervention and future disease prevention.

Sweetened beverage taxes: Economic benefits and costs according to household income

Taxing sweetened beverages has emerged as an important and effective policy for addressing their overconsumption. However, taxes may place a greater economic burden on people with lower incomes. We assess the degree to which sweetened beverage taxes in three large US cities placed an inequitable burden on populations with lower incomes by assessing spending on beverage taxes by income after taxes have been implemented, as well as any net transfer of funds towards lower income populations once allocation of tax revenue is considered. We find that while lower income populations pay a higher percentage of their income in beverage taxes, there is no difference in absolute spending on beverage taxes per capita, and that there is a sizable net transfer of funds towards programs targeting lower income populations. Thus, when considering both population-level taxes paid and sufficiently targeted allocations of tax revenues, a sweetened beverage tax may have characteristics of an equitable public policy.

Establishing 24-Hour Urinary Sucrose Plus Fructose as a Predictive Biomarker for Total Sugars Intake

BACKGROUND

Twenty-four-hour urinary sucrose and fructose (24uSF) has been studied as a biomarker of total sugars intake in two feeding studies conducted in the United Kingdom (UK) and Arizona (AZ). We compare the biomarker performance in these populations, testing whether it meets the criteria for a predictive biomarker.

METHODS

The UK and AZ feeding studies included 13 and 98 participants, respectively, aged 18 to 70 years, consuming their usual diet under controlled conditions. Linear mixed models relating 24uSF to total sugars and personal characteristics were developed in each study and compared. The AZ calibrated biomarker equation was applied to generate biomarker-estimated total sugars intake in UK participants. Stability of the model across AZ study subpopulations was also examined.

RESULTS

Model coefficients were similar between the two studies [e.g., log(total sugars): UK 0.99, AZ 1.03, P = 0.67], as was the ratio of calibrated biomarker person-specific bias to between-person variance (UK 0.32, AZ 0.25, P = 0.68). The AZ equation estimated UK log(total sugar intakes) with mean squared prediction error of 0.27, similar to the AZ study estimate (0.28). Within the AZ study, the regression coefficients of log(total sugars) were similar across age, gender, and body mass index subpopulations.

CONCLUSIONS

Similar model coefficients in the two studies and good prediction of UK sugar intakes by the AZ equation suggest that 24uSF meets the criteria for a predictive biomarker. Testing the biomarker performance in other populations is advisable.

IMPACT

Applications of the 24uSF biomarker will enable improved assessment of the role of sugars intake in risk of chronic disease, including cancer. See related commentary by Prentice, p. 1151.

Population Impact of Sugar-Sweetened Beverages on Dental Caries and Overweight/Obesity in Australian Children

KNOWLEDGE TRANSFER STATEMENT

The reported findings greatly consolidated evidence of detrimental effects of sugars intake on child oral health and overweight and obesity, some of the most prevalent chronic conditions in children. Evidence on population impact of sugars intake is directly informative to policy makers and the public about the potential impact of population-based programs targeting sugars intake to prevent dental caries and overweight and obesity.

Trajectories of Sugar Consumption and Dental Caries in Early Childhood

This study verifies the association between the trajectory of sugar consumption and dental caries in the 2015 Pelotas Birth Cohort in Pelotas, Brazil. It was conducted with data from the follow-ups at 3, 12, 24, and 48 mo from the 2015 Birth Cohort, which included 4,275 children born alive in hospitals in Pelotas. Data collection included standardized questionnaires for first caregivers applied by trained interviewers at all follow-ups. Exposure was the trajectory of sugar consumption from 3 to 48 mo (always low, always intermediate, increasing, and always high), obtained by group-based trajectory modeling. The outcome of this study was dental caries, obtained through clinical examination performed by calibrated dentists at 48 mo of age. Socioeconomic conditions and oral health instruction from a health professional during the first 4 y of life were included in the analysis as potential confounders. Prevalence ratios and their 95% confidence intervals were provided from generalized estimating equations with a log-Poisson with robust variance specification. In total, 3,654 (91.1%) children participated in the survey at 48 mo, and 2,806 children had complete data for the analyzes performed. Of these, 1,012 (36.1%; 95% confidence interval [CI], 34.3-37.8) experienced caries, and 723 (25.8%; 95% CI, 24.2-27.4) had cavitated caries. Regarding cavitated caries, the prevalence was 1.48 times higher in the group with increasing sugar consumption than children with always low consumption. There is an association between the trajectory of sugar consumption and dental caries at 48 mo. Children with increasing and always high sugar consumption have the highest prevalence of caries.

Effectiveness of Nutritional Strategies on Improving the Quality of Diet of Children from 6 to 12 Years Old: A Systematic Review

Dietary habits, that are formed during childhood and consolidated in adulthood, are known to influence the development of future chronic diseases such as metabolic syndrome or type 2 diabetes. The aim of this review was to evaluate the effectiveness of nutritional interventions carried out in recent years focused on improving the quality of the diet of the child population. A systematic search of the PubMed and Scopus databases was performed from January 2011 until September 2021. A total of 910 articles were identified and screened based on their title, abstract and full text. Finally, 12 articles were included in the current systematic review. Of those, in six studies the intervention was based on the provision of healthy meals and in the other six studies the intervention focused on modifying the school environment. Six of the studies selected included other components in their intervention such as nutritional education sessions, physical activity and/or families. A wide variety of methods were used for diet assessments, from direct method to questionnaires. The results suggest that interventions that modify the school environment or provide different meals or snacks may be effective in improving children’s dietary patterns, both in the short and long term. Further research is necessary to evaluate the real effectiveness of strategies with multidisciplinary approach (nutritional sessions, physical activity and family’s involvement).

A randomised clinical trial to investigate the effect of dietary protein sources on periodontal health

AIM

The aim was to assess two macronutrient interventions in a 2x2 factorial dietary design to determine their effects on oral health.

MATERIALS AND METHODS

Participants (65-75 years old) with a BMI between 20-35 kg/m² of a larger RCT who consented to an oral health assessment were recruited. They had ad libitum access to one of four experimental diets (omnivorous higher fat or higher carbohydrate, semi-vegetarian higher fat or higher carbohydrate) for 4 weeks. Periodontal examination included periodontal probing depth (PPD), clinical attachment level (CAL) and bleeding on probing. Oral plaque and gingival crevicular fluid (GCF) were collected before and after the intervention.

RESULTS

Between baseline and follow up the number of sites with a CAL <5 mm (mean difference (MD) -5.11±9.68, P=0.039) increased and the GCF amount (MD -23.42±39.42 Periotron Units (PU), P=0.050) decreased for the semi-vegetarian high fat diet. For the mean proportion of sites with PPD reduction >1 mm and CAL gain >1 mm significant differences were calculated between the diets investigated. The clinical parameters were not associated with changes of the oral microbiota.

CONCLUSION

The results of this study provided evidence that a semi-vegetarian higher fat diet provides benefits to clinical parameters of periodontal health. ACTRN12616001606471. This article is protected by copyright. All rights reserved.

Seasonal variation in added sugar or sugar sweetened beverage intake in Alaska native communities: an exploratory study

Excess added sugar intake contributes to tooth decay risk in Alaska Native communities. The goal of this exploratory study was to determine if there is seasonal variation in total added sugar intake or in the leading sources of added sugars in a Yup'ik population. Data were collected in spring and winter from 2008-2010 using self-reported intake data measured by 24-hour recall and by hair biomarker (carbon and nitrogen stable isotope). Seventy Yup'ik participants ages 14-70 years were recruited from two communities and data were collected twice from a subset of 38 participants. Self-reported added sugar intake (g/day), biomarker-predicted added sugar intake (g/day), and leading sources of added sugar were calculated. Seasonal variation was evaluated using a paired sample t-test. Total added sugar intake was 93.6 g/day and did not significantly differ by season. Sodas and other sugar-sweetened beverages (e.g. Tang, Kool-Aid) were the leading sources and added sugar from these sources did not significantly differ by season (p=.54 and p=.89, respectively). No seasonal variation in added sugar intake was detected by either self-report or biomarker. Dietary interventions that reduce intake of added sugars have the potential to reduce tooth decay in Yup'ik communities.

Primary Health Care Intervention Reduces Added Sugars Consumption During Childhood

OBJECTIVE

To investigate the effectiveness of a training program for health workers regarding infant feeding practices to reduce sugar consumption in children.

DESIGN

A cluster randomized trial was conducted at 20 health centers in southern Brazil randomly assigned to an intervention (n = 9) or control (n = 11) group.

PARTICIPANTS

The 715 pregnant women enrolled were assessed when their children were aged 6 months, 3 years, and 6 years.

INTERVENTION

A training session for primary care workers based on the Brazilian National Guidelines for Children.

MAIN OUTCOME MEASURE

Mothers were asked when sugar was first offered to children. Added sugars intake was obtained from dietary recalls.

ANALYSIS

The effectiveness of the intervention was modeled using generalized estimation equations and Poisson regression with robust variance.

RESULTS

Children attending intervention health centers had a 27% reduced risk of sugar introduction before 4 months of age (relative risk, 0.73; 95% confidence interval [CI], 0.61-0.87) as well as lower added sugars consumption (difference, -6.36 g/d; 95% CI, -11.49 to -1.23) and total daily energy intake (difference, -116.90 kcal/d; 95% CI, -222.41 to -11.40) at 3 years of age.

CONCLUSIONS AND IMPLICATIONS

Health care worker training in infant feeding guidelines may be an effective intervention to delay the introduction of added sugars and lower the subsequent intake of added sugars in infants and toddlers.
