Special Issue Information

Dear colleagues,

Oral diseases impair quality of life and have a negative impact on self-esteem, eating ability, causing pain, anxiety and impaired social functioning. They present a significant burden on health care systems around the world and are also recognised as a significant contributor to general health.

Excess consumption of sugars is harmful for both general and oral health. There is large quantity of good quality and strong evidence to suggest an association between high intake of free sugars and both general and oral health related diseases. Diet and nutrition play an important role in the promotion and maintenance of good oral health throughout the entire life course. Their role in the etiology and prevention of oral diseases is well established. Some of the oral conditions influenced by diet and nutrition include dental caries, developmental defects of enamel, dental erosion, periodontal disease, and oral cancer.

For the first time in 1990, the World Health Organization (WHO) recommended the consumption of free sugars to be less than 10% of our dietary intake. The WHO updated the recommendations in 2003, again recommending populations consume <10% energy intake from free sugars. In 2015, using the WHO revised framework for Guideline Development the WHO developed a Guideline for Sugars Intake for Adults and Children which made a strong recommendation that individuals limit consumption of free sugars to <10% of energy intake and preferabley to <5% energy intake, to protect oral health throughout the life-course.

This Special Edition is intended to provide current research and policy developments on diet, nutrition and oral health. This issue is open to any subject area of public health, health promotion, economics, and policy related to the diet and nutritional determinants of oral health across the life course. The listed keywords suggest just a few of the many possibilities.

Abstract: Population-level evidence of impact of sugars is needed to inform prevention. This study investigated population impact of sugar-sweetened beverage (SSB) intake on overweight/obesity and dental caries in Australian children. The National Child Oral Health Study collected parent-completed data (socioeconomic status, health behaviors, SSB consumption) and standardized oral examinations for dental caries in the primary dentition of children aged 5–8 years. The outcomes (prevalence of caries and overweight/obesity) were assessed in multivariable regression models with robust standard error estimation to estimate prevalence ratios (PR) with SSB intake as the main exposure, and adjusted for covariates. Population Attributable Fraction (PAF) was calculated using population distribution of the exposure and adjusted PRs. Data were weighted to produce population-representative estimates. Among 7,021 children, some 19% children consumed more than two (2+) SSB per day. Prevalence of dental caries and overweight/obesity was 35.8% and 28.7%, respectively and were strongly associated with SSB consumption. Adjusted PRs for 2+SSB intake/day for having dental caries and overweight/obesity was 1.45 (95% Confidence Interval (CI): 1.27-1.66) and 1.49 (95% CI: 1.28-1.74), respectively. PAF of SSB consumption was 27% (95% CI: 18–35) for dental caries and 23% (95% CI: 11–34) for overweight/obesity. SSBs attributed significantly to both dental caries and overweight/obesity in Australian children. Health promotion programs targeting SSB consumption will help to improve both child oral and general health.

Abstract: Overweight, obesity and early childhood caries (ECC) are preventable conditions affecting infants and young children. Etiology may be linked, with overlapping obesogenic and cariogenic feeding behaviours, such as increased sugar exposure through bottle propping, night-time bottle feeding and sugar-sweetened beverages. Best-practice bottle feeding and transition to cup use may reduce overweight, obesity and ECC. An integrative review was undertaken to identify interventions that support best-practice formula feeding or bottle cessation in infants and children and examine their effectiveness on formula feeding practice, bottle cessation, oral health and weight outcomes. 26 studies were included for analysis, with 17 focused on populations vulnerable to ECC or infant overweight and obesity from formula use. Outcomes varied, with 14 studies with mixed outcomes and eight studies with worsened post-intervention outcomes; while some studies reported improvements, improvements were not maintained long-term and many were at risk of bias in study design. Many studies focused on parent education, counselling or resource distribution, but few studies utilised a behaviour change theory that addressed antecedents to obesogenic or cariogenic behaviour. Interdisciplinary approaches and consumer co-design for interventions prevent ECC and child overweight must be considered as a holistic approach to design intervention messages and support behaviour change.
