Fewer Children in Families Associated with Lower Odds of Early Childhood Caries: A Sample from Three Countries.

Childhood caries experience is influenced by family characteristics and oral health practices in the context of many social-commercial determinants. The aim of this study was to explore the relationship between families' number of children, oral health practices and child caries experience in a convenience sample of 1374 children aged 6 months through 6 years and their families from Ecuador, Nepal, and Vietnam. Data were collected by mother interviews and child dental exams. Multivariate logistic and Zero-Inflated-Poisson regression analyses assessed associations between number of children, oral health practices and decayed, missing or filled teeth (dmft). Families had a mean of 2.2 children (range 1-12); 72% of children had tooth decay, with mean dmft of 5.4. Adjusting for child age, sex, and urban/rural location, a greater number of children in the family was associated with significantly less likelihood of unhealthy bottle feeding practices, having a toothbrush/toothpaste and parent helping child brush, and being cavity-free; higher number of dmft, and greater likelihood of having a dental visit. Early childhood oral health promotion should include focus on oral hygiene and healthy feeding-particularly breastfeeding and healthy bottle feeding practices-as well as access to family planning services and support for childcare.

Cross-Sectional Analysis of Oral Healthcare vs. General Healthcare Utilization in Five Low- and Middle-Income Countries.

Oral health is integral to overall health and is often neglected, especially in low- and middle-income countries (LMICs). Oral disease, including untreated dental caries, affects nearly 3.5 billion people globally, contributing to poor health and quality of life. To examine the relationship between the utilization of general healthcare and oral healthcare, we conducted an exploratory cross-sectional study of first-visit interview data collected from a convenience sample of 3,422 low-income mothers and 4,324 children aged 6 months through 6 years participating in a community-based oral health and nutrition program in five LMICs (Ecuador, El Salvador, India, Nepal, and Vietnam) from 2006-2015. We used descriptive and exploratory association analysis to identify patterns of oral healthcare utilization for mothers and children compared to medical care utilization, specifically maternal prenatal care and child immunizations. Overall, 89.6% of the mothers had received prenatal care for at least one child, but only 76.4% had ever received dental care and 50% were currently suffering from oral health symptoms, primarily oral pain. Mothers who received prenatal care were significantly more likely to have accessed dental care compared to those who had not received prenatal care (OR = 2.62, 95% CI: 2.06, 3.32). Overall, 95.4% of the children had current immunizations, but only 30.1% had ever received dental care, and 32.4% were currently suffering from oral pain. Children whose immunizations were up-to-date were more likely to have received dental care, with a significant association in Ecuador (OR = 3.29, 95% CI: 2.06, 5.30). Compared to utilization of general healthcare, oral healthcare was under-utilized by mothers and children in our sample from five LMICs. Integration of prevention- and treatment-oriented oral healthcare into primary medical care services, particularly prenatal care and child immunizations, could help increase access to oral healthcare and improve women's and children's oral health.

Associations between Maternal Education and Child Nutrition and Oral Health in an Indigenous Population in Ecuador.

The global nutrition transition has increased the prevalence of childhood dental caries. Greater understanding is needed of the impact of social determinants­including maternal education­on child oral health. This is a cross-sectional analysis of a convenience sample of families of 458 indigenous Ecuadorian children aged 6 months through 6 years from 2011−2013. Data was collected by mother interviews and child dental and anthropometric examinations. Multivariate logistic and Zero-Inflated-Poisson regression analyses assessed associations between years of maternal education and maternal-child oral health practices and child oral health outcomes. Each additional year of maternal education was significantly (p < 0.05) associated with some healthier practices including greater likelihood of mothers and children drinking milk daily (OR 1.20; 95% CI 1.08, 1.34); and less healthy practices including greater likelihood of bottle-feeding children with sugary liquids (OR 1.14; 95% CI 1.06, 1.22) and to older age, giving children sweets daily, calming children with a bottle or sweets, and less likelihood of helping brush their children's teeth (OR 0.93; 95% CI 0.88, 0.98). Each year of maternal education had a small but statistically non-significant influence on increasing the odds of children being among those who are cavity-free (OR 1.03; 95% CI 0.92, 1.16). Interventions to improve health outcomes should focus not just on maternal education but also address social and commercial determinants of health through nutrition and oral health education, as well as policies to reduce sugar and ensure universal access to oral health care.
