ASSOCIATION BETWEEN EARLY CHILDHOOD CARIES AND MALNUTRITION IN A SUB-URBAN POPULATION IN NIGERIA
Abstract Background To determine the association between malnutrition and early childhood caries (ECC) in preschool children resident in sub-urban, Nigeria. Methods This is a secondary analysis of a cross sectional study with data generated through a household setting. Variables (sex, frequency of sugar consumption, maternal knowledge of oral hygiene, oral hygiene status) associated with ECC in a primary study conducted in the Ile-Ife, Nigeria, were adjusted for using Poisson regression analysis. Results Of the 370 pre-school children, 20 (5.4%) were underweight, 20 (5.4%) were overweight, 67 (18.1%) were wasting, and 120 (32.4%) were stunted. Factors associated positively or negatively with ECC were stunted, underweight, overweight and fair oral hygiene. The prevalence of ECC was lower in children who were stunted (APR: 0.16), almost seven times higher in children who were overweight (APR: 6.88), and predictively absent in children who were underweight (APR: 0) when compared with children who had normal weight. Non-significant risk indicators for ECC included consuming sugar between meals three times a day or more (APR: 2.18), having low socioeconomic status (APR: 2.4) and being female (APR: 2.9). Conclusions For this study population, the indicators of malnutrition – being stunted, underweight, overweight - and fair oral hygiene were risk indicators for ECC, while the frequency of sugar consumption was not a significant risk indicator. Further studies are needed to identify if there are other mediators of an association between ECC and nutrition apart from sugar consumption.
