Malnutrition may be a risk factor for early childhood caries (ECC) for several reasons. A plausible biological link between the two conditions is through salivary gland hypo-function: Malnutrition causes decreased flow of saliva, reduces salivary buffering capacity, and changes the composition of the saliva constituents. 1 Nutritional status and ECC also share behavioural risk factors related to poor dietary habits and food choices. Overweight/obesity and ECC result from high consumption of free sugar. 2-4 Wasting and stunting are forms of protein-energy malnutrition associated with the risk of developing enamel defects, increase in plaque accumulation, and caries. 5 Malnutrition and ECC are also the results of social equity problems; both are
Aim: To determine the association between maternal education, income, and decision-making status and the presence of early childhood caries (ECC) and dental-service utilization among young children. Methods: This cross-sectional study was based on data from a household survey of 1,549 mother-preschool-aged-child dyads conducted in Ife Central Local Government Area, Nigeria. The explanatory variables were maternal education, income, and decision-making status (related to healthcare, large household purchases, and visits to family/relatives). Outcome variables were the presence of ECC and the child's history of dental-service utilization. Poisson regression analyses were conducted to identify factors associated with outcomes; the models were adjusted for maternal age, child's socioeconomic status, oral hygiene status, and frequency of sugar consumption. Results: The study recruited 1,549 mother-child dyads, of which 66 (4.3 percent) children had ECC, and 90 (5.9 percent) children had a history of dental-service utilization. Fewer than half (42.3 percent) of the mothers earned between N18,001($49.00) and 60,000 ($168.00) per month. Also, 896 (57.8 percent) reported not making any independent decisions, 152 (9.8 percent) made one of three decisions independently, and 313 (20.2 percent) made two or three decisions independently. In the adjusted model, children of mothers with monthly income higher than N60,000 were more likely to have used dental services than were those whose mother's monthly income was less than or equal to N18,000 (adjusted prevalence ratio = 2.29; 95%CI: 1.30-4.02; P = 0.004). No other maternal factor was associated with ECC. Conclusions: Although maternal socioeconomic factors and decision-making abilities were not associated with ECC prevalence, more preschool children whose mothers had high income used dental services.
Background: This study assessed the direct, indirect and total effect of distalpolitical-risk indicators (affecting populations), and proximal risk indicators (affecting women) on the global prevalence of early childhood caries (ECC) in 3-5 year old children. Methods: Data on global ECC prevalence were obtained from a prior study. Data for distal risk indicators (voice and accountability; political stability/absence of terrorism; control of corruption) were obtained from the World Bank Governance indicators, 2016. Data for proximal risk indicators (women's opportunity for leadership; percentage of female legislators, top officials and managers; basic employability status of women; ability of women to afford time off work to care for newborns; gross national income (GNI) per capita for females) were derived from the Human Development Index, 2016. Associations between variables were assessed with path analysis. Results: Voice and accountability (β = − 0.60) and GNI per capita for females (β = − 0.33) were directly associated with a lower ECC prevalence. Political stability/absence of terrorism (β =0.40) and higher percentage of female legislators, senior officials and managers (β = 0.18) were directly associated with a higher ECC prevalence. Control of corruption (β = − 0.23) was indirectly associated with a lower ECC prevalence. Voice and accountability (β = 0.12) was indirectly associated with a higher ECC prevalence. Overall, voice and accountability (β = − 0.49), political stability/absence of terrorism (β = 0.34) and higher female GNI (β = − 0.33) had the greatest effects on ECC prevalence. Conclusion: Distal risk indicators may have a stronger impact on ECC prevalence than do proximal risk indicators.. Approaches to control ECC may need to include political reforms.
Background There is little is known about the factors associated with caries experience and gingivitis among 6–11-year-old children in Nigeria. The aim of the study was to determine the prevalence and preventive oral health behaviors associated with caries and gingivitis among 6–11-year-old children in Nigeria. Methods A cross-sectional questionnaire-based survey was conducted in Ile-Ife, Nigeria. The dependent variables were caries and gingivitis. The dmft/DMFT index was used to assess dental caries experience (present or absent) and caries severity. The gingival index was used to assess the prevalence (present or absent) and severity of gingivitis (healthy gingiva/mild gingivitis versus moderate/severe gingivitis). The independent variables were preventive oral health behaviors (frequency of daily tooth brushing, frequency of consumption of refined carbohydrates in-between-meals, use of fluoridated toothpaste, and use of dental floss, history of dental service utilization). A series of logistic regression analysis models were constructed to determine the associations between the dependent and independent variables after adjusting for confounders (age, sex, and socioeconomic status). Results There were 69 (5.2%) children with caries. The mean (standard deviation) dmft was 0.08 (0.457) and the mean DMFT was 0.02 (0.159). There were 839 (63.3%) children with gingivitis with a mean (SD) gingival index score of 0.503 (0.453). Children who seldom or never used fluoride toothpaste had significantly higher odds of developing moderate to severe gingivitis (AOR; 1.671; 95% CI: 1.003–2.786; p = 0.049). Children with middle socio-economic status had significantly lower odds of developing moderate to severe gingivitis (AOR: 0.573; 95%CI: 0.330–0.994; p = 0.048). There were no risk indicators identified for caries. Conclusion The prevalence of dental caries was low while the prevalence of gingivitis was high in the study population. The daily used of fluoridated toothpaste seem to reduce the risk for moderate/severe gingivitis. Further studies are needed to understand these findings.
