BackgroundThis study aims to cross-culturally adapt the original English-language COHIP-SF 19 to Arabic culture and to test its psychometric properties in a community sample.MethodsThe Arabic COHIP-SF 19 was developed and its psychometric properties were examined in a population-based sample of 876 schoolchildren who were aged 12 years of age, in Benghazi, Libya. The Arabic COHIP-SF 19 was tested for its internal consistency, reproducibility, construct validity, factorial validity and floor as well as ceiling effects. A Mann-Whitney U test was used to compare the mean scores of COHIP-SF 19 by participants’ caries status and self-reported oral health rating, satisfaction and treatment need.ResultsThe Arabic COHIP-SF 19 was successfully and smoothly developed. It showed an acceptable level of equivalence to the original version. Overall, the internal consistency and reproducibility were acceptable to excellent, with a Cronbach’s alpha of 0.84 and an intra-class correlation coefficient (ICC) of 0.76. All hypotheses predefined to test construct validity were confirmed. That is, children who had active dental caries, and who rated their oral health as poor, were not satisfied with their oral health or indicated the need of treatment had lower COHIP-SF 19 scores (P < 0.05). Floor or ceiling effects were not observed. The exploratory Factorial analysis suggested a 4-component solution and deletion of one item.ConclusionThe Arabic COHIP-SF 19 was successfully developed. The measure demonstrated satisfactory reliability and validity to estimate OHRQoL in a representative sample of 12-year-old schoolchildren.
Objective The current study aimed to assess the caries experience and associated factors and its impact on the oral health-related quality of life (OHRQoL) among 6-year-old Libyan children. Methods A cross-sectional survey including 706 six-year-old children was conducted in 2017 in Benghazi, Libya. Data were collected through a self-administered questionnaire assessing socioeconomic status and oral health behaviours, and the Arabic version of the Early Childhood Oral Health Impact Scale (A-ECOHIS) to assess the OHRQoL. Clinical examination assessed caries experience at tooth level (dmft) and the number of decayed, missing due to caries and filled teeth (dt, mt and ft). Poisson regression analysis was performed to determine the association between dmft scores and the independent predictors. Linear regression analysis was conducted for ECOHIS scores with the children’s gender, SES and OHB. The statistical significance was set to ≤ 0.05. Results Data were available for 706 children. Caries prevalence (dt) and dmft of ≥ 1 were 69.1% and 71% respectively. The mean ± SD dmft score was 3.23 ± 3.32. There was a significant and direct association between dmft scores and daily consumption of sugary snacks (B = 1.27, P = 0.011) and a significant inverse association with teethbrushing twice daily (B = 0.80, P = 0.041). There was a significant and direct association between A-ECOHIS and dmft (B = 1.14, P ≤ 0.001) and a significant and inverse association between A- ECOHIS and high and intermediate family income compared to low income (B = −3.82, P = 0.0001 and B = −2.06, P = 0.028). Conclusions 6-year-old Libyan children had a relatively high caries experience an untreated decay with impact on OHRQoL. Social disparities, sugar consumption patterns and oral hygiene practices were associated with high caries experience.
Background Dental caries and Obesity in children are issues of public health concern. Even though researching the relationship between these two noncommunicable diseases has been conducted for many years, the results remain equivocal. This paper aimed to examine the association between dental caries and obesity among 12-year-old schoolchildren living in war-affected environment in Benghazi. Methods A secondary analysis of a cross-sectional study was conducted to determine the prevalence of caries among 12-year-old school children in Benghazi in 2017 during the armed conflict that affected the city. The data extracted for the analysis included sociodemographic of the participants (gender, maternal education and school type), caries experience (DMFT index), and anthropometric measures (height in cm, weight in kg, BMI and Z score for BMI). Comparisons of anthropometric measures were conducted according to caries experience. Linear regression models were developed to determine the association between Body Mass Index and Z score as outcome variables, caries as an explanatory variable, and covariates (gender, maternal education and school type). Beta coefficient (β) and 95% confidence intervals were calculated. All statistical tests were conducted at p ≤ 0.05. Results There were 782 children with a mean (SD) BMI of 20.7 SD5.09 and an average z (SD) score of 0.56 SD1.51. Also, 159 (20%) children had obesity. No significant association was observed between caries and anthropometric measures. However, higher BMI was observed in children from a private school (p ≤ 0.001***), females (p ≤ 0.001***) and self-reported regular sugary drinks consumers (p ≤ 0.001***). Conclusion The present study shows no significant association between dental caries and anthropometric measures. However, the study findings support the notion of tackling sugar intake as a common risk factor for caries and obesity, which should be encouraged in the Libyan culture.
