Abstract

Introduction: Severe early childhood caries (S-ECC) is a significant public health problem, particularly in developing countries like Indonesia. Early childhood feeding practices are recognized as major risk factors, but prospective data from specific regions like Medan, Indonesia, are limited. This study aimed to investigate the association between various feeding practices and the development of S-ECC in a cohort of children in Medan. Methods: A prospective cohort study was conducted involving 450 mother-child dyads recruited from Posyandu (integrated health posts) in Medan, Indonesia. Baseline data on maternal demographics, socioeconomic status, oral health knowledge, and infant feeding practices were collected via questionnaires and interviews. Children were followed up at 6-month intervals for 36 months. Dental examinations were performed by calibrated dentists using the dmft index (decayed, missing, filled teeth) to diagnose S-ECC. Cox proportional hazards regression was used to analyze the association between feeding practices and S-ECC development, adjusting for potential confounders. Results: The incidence of S-ECC at 36 months was 38.2% (n=172). Prolonged bottle feeding (beyond 12 months) (Hazard Ratio [HR] = 2.15; 95% Confidence Interval [CI]: 1.55-2.98; p<0.001), nocturnal bottle feeding with sweetened liquids (HR = 2.85; 95% CI: 2.01-4.03; p<0.001), and frequent consumption of sugary snacks/drinks (≥3 times/day) (HR = 1.92; 95% CI: 1.38-2.67; p<0.001) were significantly associated with an increased risk of S-ECC. Exclusive breastfeeding for the first 6 months showed a protective effect (HR = 0.62; 95% CI: 0.45-0.86; p=0.004), even after adjusting for socioeconomic status and maternal oral health knowledge. Conclusion: This study confirms the significant impact of early childhood feeding practices on S-ECC development in Medan, Indonesia. Prolonged and nocturnal bottle feeding, particularly with sweetened liquids, and frequent consumption of sugary snacks/drinks were key risk factors. Promoting exclusive breastfeeding for the first six months and educating mothers about appropriate feeding practices are crucial for S-ECC prevention in this population.

Abstract

Introduction: Documented consent without demonstrable comprehension is medicolegally insufficient, yet comprehension-based informed consent (IC) failure in collectivistic surgical populations is largely unquantified. Methods: This re-analysis of a previously reported cross-sectional dataset assessed IC efficacy among 320 consecutive adults undergoing high-risk elective surgery (ASA physical status III–IV) at Private Hospital X, Palembang, Indonesia, in 2024, reported per STROBE. Six instruments standardised to 0–100 were administered, including the IC Comprehension Score (ICCS) and the five-domain composite IC Efficacy Score (ICE); adequacy was ICE ≥ 70. Exact intervals and permutation tests, effect sizes, areas under the receiver operating characteristic curve recovered from Mann–Whitney U statistics, E-values, fragility indices, standardisation and a partial-identification audit were added. Results: Only 19 of 320 patients (5.9%, 95% CI 3.6–9.1) achieved adequate IC efficacy, below both published comparators reporting an explicit adequacy proportion (exact binomial P < 0.001 versus 14.0% and versus 35.8%); standardisation to lower-education distributions reduced this to 2.74–3.79%, so 5.9% is an upper bound. Adequacy rose monotonically across educational strata from 0.0% to 13.3% (exact Cochran–Armitage z = 3.66, P = 0.0003; tertiary versus secondary education or below, odds ratio 8.27, 95% CI 2.36–29.00; E-value 14.29; fragility index 8). ICCS was the only independent predictor in an exploratory multivariable model with 2.71 events per variable (odds ratio 13.75 per SD, 95% CI 3.32–56.92), an association partly constitutive because comprehension is one ICE domain. Neither family influence nor collectivism predicted adequacy. Conclusion: Comprehension, not cultural collectivism, gates valid surgical consent.
