Background The purpose of this study was to examine the associations of physical activity (PA), recreational screen time, and sleep with indicators of poor oral health in youth. Methods Participants were children and adolescents whose parents completed the 2022 National Survey of Children’s Health (N = 34,342; 49% female; Mean age = 11.9 +/- 3.5 years). The dependent variables were three binary response items that indicated the presence of toothaches, bleeding gums, and cavities within the previous 12 months. Independent variables were three items indicating the weekly frequency of 60 min of PA, hours of recreational screen time, and hours of weeknight sleep. Relationships between variables were examined using double-selection logistic regression with demographic, dietary, oral hygiene, and dental service covariates selected using the plug-in method of the least absolute shrinkage and selection operator. Results Compared to zero days of PA, 4–6 days of PA per week was associated with 30% lower odds of bleeding gums (p = 0.021). Compared to less than 1 h of recreational screen time, 2 h or more hours of recreational screen time were associated with a 1.26 to 1.62 times higher odds of cavities (p < 0.01). Compared to 5 h or less of sleep, 7 to 10 h of sleep was associated with 47–61% lower odds of bleeding gums and 31–47% lower odds of cavities (p < 0.01). Secondary analyses indicated that at least 2 of the movement behavior recommendations had to have been adhered to for positive associations with indicators of oral health to be observed. For toothaches, bleeding gums, and cavities, meeting 2 or 3 recommendations was associated with lower odds of poor oral health; whereas adhering to only one recommendation was not. Conclusion Children with higher PA and sleep durations had improved oral health indicators and children with longer periods of screen time exposure had poorer oral health indicators. Our findings recommend adhering to multiple movement behavior recommendations to achieve improvements in oral health indicators.

Background The Coronavirus disease 2019 pandemic increased global psychological distress, emotional distress, and sleep disturbances, all known risk factors for compromised oral health. Despite this, there is limited understanding of the impacts of these psychological factors on oral health in certain populations, including Iranians. Thus, the present study investigates the associations between sociodemographic characteristics, emotional distress, sleep pattern changes, tooth brushing frequency, and oral ulcer reports in a sample of Iranian adults during the Coronavirus disease 2019 pandemic. Materials and methods This cross-sectional, web-based study collected data from Iranian adults between July and September 2022 using respondent-driven sampling. The Mental Health and Wellness questionnaire was used to gather information on sociodemographic characteristics, emotional distress, sleep pattern changes, toothbrushing frequency, and oral ulcer reports. Simple and multiple logistic regression served for statistical analysis. Results Among the 240 participants, comprising 164 females and 76 males, with a mean age of 35.3 years (±13.3), 28 individuals (11.7%) reported reduced tooth brushing frequency, and 35 individuals (14.6%) reported oral ulcers. Male gender (OR = 2.75, p = 0.016) and sleep patterns changes (OR = 2.93, p = 0.01) increased the likelihood of reduced tooth brushing frequency. Additionally, being younger than 30 (OR = 2.87, p = 0.025) and fearing coronavirus transmission (OR = 3.42, p = 0.009) increased the odds of oral ulcers. Conclusions Male gender and sleep pattern changes were risk factors for reduced tooth brushing frequency among the present sample of Iranian adults during the Coronavirus disease 2019 pandemic. Additionally, being under 30 and fearing coronavirus transmission were identified as risk factors for oral ulcers in this population. To preserve and promote adults’ oral health during public health crises, targeted educational initiatives, public health awareness campaigns, and integrated mental and oral healthcare approaches are encouraged.

Background & Aims: Dental caries and non-alcoholic fatty liver disease (NAFLD) overlap in risk factors and etiology, but the relationship remains unexplored.. Methods 6650 participants of the National Health and Nutrition Examination Survey (NHANES), 2017–2020 were included. Two multivariable logistic regression models were employed to evaluate the relationship among untreated dental caries (UDC) and liver conditions of NAFLD and fibrosis, with adjustments for demographics, lifestyle and medical history. Further more, two-sample Mendelian randomization (MR) was performed with caries as exposure and NAFLD with NAFLD-related conditions as outcome, and vice versa for bidirectional causality validation. Results In the observational research, UDCs were notably associated with NAFLD (OR: 1.40, 95% CI: 1.06–1.86) and significant fibrosis (SF) (OR: 1.29, 95% CI: 1.03–1.62). NAFLD and SF showed significant associations with UDCs (OR: 1.40, 95% CI: 1.08–1.83; OR: 1.62, 95% CI: 1.26–2.08). In MR analysis, dental caries had an insignificant risk towards liver conditions. In contrast, caries were insignificantly protected by liver conditions. Conclusions Observational studies suggested a significant association between UDC and liver conditions of NAFLD and fibrosis. However, MR suggested an insignificant causal relationship of caries with liver conditions; reversely, liver conditions had a protective effect on caries.
