Background The health of migrant workers is becoming an important public health issue. Although there are an increasing number of migrant workers in Korea, the health status in migrant populations remains unknown. The aims of this study were (1) to evaluate the association between income and self-rated oral health (SROH), and (2) to assess the role of health insurance and self-perceived discrimination in the association between income and SROH among Indonesian migrant workers in Korea. Methods Information about self-reported income, SROH, coverage/utilization of health insurance (HI), living difficulties related to oral health (LDROH), oral health literacy (OHL), and discrimination were obtained from Indonesian migrant workers in Korea (n = 248). The main explanatory variable was income, and SROH was an outcome variable. Logistic regression analyses were performed controlling for age, gender, HI, LDROH, OHL, and discrimination. The paths from income to SROH were analyzed using the Partial Least Square-Structural Equation Model (PLS-SEM). Results Among Indonesian migrant workers, the lower income group had the highest probability of a poor SROH compared to the higher income group. The variables showing a high explanatory power were discrimination among the low income group and HI among the middle income group. In PLS-SEM, the variables such as HI, LDROH, OHL, and discrimination contributed 11% to explaining the association between income and SROH. Conclusion A monotonic gradient was revealed among migrant workers according to the association between income and SROH. Discrimination and HI contributed to oral health inequalities.

Aim The aims of this study were to examine inequalities in periodontitis and tooth loss among South Korean adults using the Wright's Neo‐Marxian social class (NMSC) indicator and to assess the impact of material, psychosocial, health behavioural and workplace environmental factors in the association of social class with oral health. Methods This study used the data from the 4th Korea National Health and Nutrition Examination Survey with 6710 participants aged 19‐54 years old. Participants were classified into 12 social class positions based on the Wright's social class map. Healthy gum and absence of tooth loss were the health outcomes. Mediating factors were material (M), psychosocial (PS), health behavioural (HB) and workplace environmental (WPE) factors. A series of logistic regressions were performed to analyse the data. Odds ratio (OR) and 95% confidence interval (CI) were used to report the results. Results For the absence of periodontal pockets status, expert supervisors were the healthiest periodontal group among the social classes (OR = 2.15 95% CI 1.59‐2.90) in the age and gender adjusted model. For the absence of tooth loss, skilled workers had the highest OR for absence of tooth loss (OR = 1.64 95% CI 1.31‐2.05) in the age‐ and gender‐adjusted model. For absence of periodontal pockets, the explanatory power of the M factor was the highest in all social class positions except for nonskilled supervisors followed by the HB factor. Additionally, the absence of tooth loss had a fairly similar pattern. The explanatory power of the M factor was the highest in all social class positions except for the petty bourgeoisie (highest: HB) and nonskilled supervisors (highest: WPE) followed by the HB and WPE factors. Conclusion There were nongradient oral health inequalities among the South Korean population according to the NMSC. Oral health promotion programmes that focus on changing the socioeconomic environment and health behaviours should be implemented.

Cara pemberian makanan pada balita sedikit banyak dipengaruhi oleh tradisi budaya di suatu daerah tertentu. diantaranya adalah tradisi nasi papah atau seringkali juga disebut nasi papak yang masih banyak dilakukan oleh para ibu di beberapa wilayah di Indonesia, diantaranya di Kabupaten Lombok Timur, Propinsi Nusa Tenggara Barat. Tradisi nasi papah adalah nasi yang telah dikunyah dan dilumatkan terlebih dahulu sebelum diberikan kepada balita. Dari segi kesehatan terutama kesehatan mulut, hal ini berisiko terhadap terjadinya Early Childhood Caries(ECC). Perilaku tersebut dapat menyebabkan transmisi mikroorganisme S. mutans dari mulut ibu ke mulut anak. Tujuan Untuk mengetahui pengaruh tradisi nasi papah terhadap risiko terjadinya Early Childhood Caries. Desain yang digunakan adalah cross sectional dengan jumlah total sampel subyek penelitian sebanyak 186 anak berusia 6 – 60 bulan yang didampingi oleh ibunya, yang bertempat tinggal di Desa Senyiur, Kabupaten Lombok Timur, Nusa Tenggara Barat. Pemeriksaan Intra Oral dilakukan untuk mengukur karies gigi ibu dan anak dengan menggunakan indeks DMFT/deft dan untuk mendapatkan informasi mengenai perilaku kesehatan mulut ibu dan anak dilakukan wawancara pada ibu dengan menggunakan kuesioner. Data yang terkumpul dianalisa dengan uji Chi Square. perilaku nasi papah mempunyai risiko terhadap terjadinya ECC dengan OR 5,46 (95%CI 4,24-36,55), p
