Abstract Objective: To assess the relative importance of an orthodontic esthetic index, dental fluorosis and nonfluoride opacities, with respect to parents' satisfaction with their children's dental esthetics. Materials and Methods: Dental examinations of Iowa Fluoride Study participants assessed fluorosis and nonfluoride opacities in the mixed dentition. Dental casts of 200 randomly selected subjects were scored using the Dental Aesthetic Index (DAI) criteria. Parent satisfaction was assessed via multiple items on a questionnaire. Associations were evaluated using logistic regression. Results: Nineteen percent of parents were somewhat or very dissatisfied with their children's dental esthetics. Overall DAI score was positively associated with dissatisfaction (P < .001), as was fluorosis (P = .003). Conclusions: In addition to changes related to DAI scores, parent esthetic satisfaction decreased with the presence of fluorosis. Dental professionals should address both the issues of tooth positioning and color aberration with respect to dental esthetics.

Introduction. This study evaluated whether stages of change for physical activity (PA) predict sign-up, participation, and completion in a PA competition. Method. Deidentified data were provided to evaluate a PA competition between 16 different institutions from a public university system. Employees who completed a health assessment (HA) prior to the start of the PA competition ( n = 6,333) were included in the study. Participants completed a self-report HA and logged their PA throughout the competition. Multivariable logistic regression models tested whether stages of change predicted PA competition sign-up and completion. An ordinal logistic regression model tested whether stages of change predicted number of weeks of PA competition participation. Results. Stages of change predicted PA competition sign-up and completion, but not weeks of participation. The odds for PA competition sign-up were 1.64 and 1.98 times higher for employees in preparation and action/maintenance (respectively) compared with employees in precontemplation/contemplation. The odds for PA competition completion were 4.17 times higher for employees in action/maintenance compared with employees in precontemplation/contemplation/preparation. Conclusion. The PA competition was more likely to reach employees in preparation, action, or maintenance stages than precontemplation/contemplation. Most of the completers were likely participating in regular PA prior to the competition.

Abstract Background Hypertension (HTN) and hyperhomocysteinemia (HHcy) have been reported to be independent predictors of cognitive impairment. However, the conclusions were inconsistent and few studies had reported the combination prediction of HTN and HHcy for cognitive impairment. Our study aimed to evaluate the association between H-type HTN, HTN and HHcy and the risk of cognitive impairment.Methods We used a cross-sectional study- participants aged over 40 years, which were selected from Kailuan communities in China. Cognitive impairment was determined by MMSE scale (MMSE<24). Multivariable logistic regression was used to analyze the association of H-type HTN and cognitive impairment, and we also made stratification analysis by age of participants.Results A total of 3454 participants were included in our study, and ≥65 years old was 16.79%; the gender of male was 56.77%. The prevalence of cognitive impairment in the H-type HTN (HTN+/HHcy+) group (10.74%) was significantly higher than other three groups (2.92%, 6.42%, 5.86%, respectively). The logistic regression results showed that participants with H-type HTN was positively associated with cognitive impairment risk (OR = 2.57, 95% CI: 1.38-4.80). Similar results were observed in participants stratified by age (65 years) (<65 years old: OR =2.01, 95% CI: 0.87- 4.67 ; ≥65 years old: OR=3.63, 95% CI: 1.32-10.01).Conclusion Our finding indicated that H-type HTN was positively associated with the risk of cognitive impairment, especially in ≥ 65 years old. H-type HTN could be the major intervention measures to decrease the incidence of cognitive impairment as well as the stroke in Health Practice Management.

Aim: To determine the association between single nucleotide polymorphisms (SNPs) within the COL1A2 gene and dental fluorosis among 4- and 8-year-old Nigerian children. Methods: A cross-sectional study was undertaken among 125 four and eight-year-old Nigerian children living in naturally fluoridated areas of Ibadan, Nigeria. Drinking and cooking water samples were collected for F analysis. Buccal mucosa swabs were collected from all children and genomic DNA extracted. Presence or absence of the SNP within the COL1A2 gene was identified by PCR and DNA sequencing for 70 of the participants. Results: The median (minimum, maximum) F concentration of drinking and cooking water were 0.05 (<0.1, 3.0) mg/L and 0.01 (<0.1, 4.0) mg/L respectively. The majority of the study participants (52.9%) were heterozygous for the SNP. There was a statistically significant association between F concentration in drinking water and the occurrence of dental fluorosis (p=0.04). F concentration in drinking water was the only statistically significant predictor of dental fluorosis (p=0.03, OR=3.64(CI=1.11-11.94)) after adjusting for F concentration in cooking water and SNPs. The risk of dental fluorosis tended to increase with the presence of SNPs AA and AC (RR > 1) but this association was not statistically significant. Conclusion: The majority of the study participants had the heterozygote SNP AC genotype of COL1A2 gene. F concentration in drinking water was the only statistically significant predictor of dental fluorosis. The risk of dental fluorosis tended to increase with the presence of SNPs AA and AC (RR > 1) but was not statistically significant.

Background: Maternal and child mortality and morbidity are higher during childbirth in developing countries compared to developed countries. Institutional delivery service utilization is indispensable to improve maternal and child health.However, the proportion of women utilizing institutional delivery service in Ethiopia is very low. In addition, little is known about factors contributing to home delivery. Objectives: To assess the prevalence of home delivery and associated risk factors at Jimma Town, Southwest Ethiopia. Methods: A community-based cross-sectional study was employed on 423 study participants. Data were collected by semi-structured questionnaire through face to face interview. A systematic sampling technique was used to select study participants. After cleaning and checking completeness of collected data, data was entered into Epi data version 3.3.1 software and exported to Statistical Package for the Social Science (SPSS) version 21.0 for analysis. Logistic regression was used to find out the association between explanatory and response variables. Explanatory variables which fulfill the assumption of logistic regression and had a P-value less than 0.25 from bi-variable logistic regression were considered for the multivariable logistic regression model. The strength of association was evaluated using odds ratio at 95% confidence interval (CI) and P-value < 0.05 was considered to declare significant associations. Results: The prevalence of home delivery in this study was 36.64% (n=155/423 and it had significant association with illiteracy AOR=2.7 [(95%CI); (1.37-5.43)], multi-gravida AOR=2.12 [(95%CI); (1.09-4.10)], history of antenatal care (ANC) follow up AOR=4.15 [(95%CI); (2.57-6.70)] and husband educational status AOR=13.5 [(95%CI); (2.86-63.62)]. Conclusion: The prevalence of home delivery in this study was high compared to world health organizational recommendation. Educational status of the mother, gravida, antenatal care follow up and husband educational status were factors that had a significant association. Women empowerment through educational opportunities, increase antenatal care follow up and male involvement in maternal health service are recommended

Objective. Previous studies have shown that some metabolic risk factors are related to nonalcoholic fatty liver disease (NAFLD). This retrospective study was performed to investigate the associations between physical examinations and blood biochemistry parameters and NAFLD status and to identify possible risk factors of NAFLD. Methods. Study participants underwent general physical examinations, blood biochemistry, and abdominal ultrasound evaluations. In addition, data regarding sex, age, ethnicity, medical history, and alcohol consumption of participants were recorded. Among the study participants (N=1994), 57.8% were male, 41.2% over the age of 50, and 52.6% with BMI≥24. 986 patients had NAFLD and 1008 had no NAFLD. We used effect size analysis and logistic regression to determine which physical examinations and blood biochemistry parameters were significant for the association between these parameters and NAFLD status. Results. Both the effect size and logistic regression indicated that BMI, diastolic blood pressure (DBP), triglycerides (TG), and serum uric acid (SUA) show a significant association with NAFLD. Females are overall at a higher risk of NAFLD, but factors such as high BMI, DBP, TG, and SUA increase the associated risk for both sexes. Compared with males, females have a higher risk of NAFLD given that they are over 50, overweight and obese (BMI at or over 24), or have high SUA. In terms of age, people older than 50 with high SUA, and people younger than 50 with high DBP and low-density lipoprotein cholesterol (LDL-C) all increase the risk of NAFLD. For BMI, high DBP and low high-density lipoprotein cholesterol (HDL-C) are risk factors for NAFLD in overweight and obese people (BMI at or over 24), whereas in normal weight and underweight people (BMI under 24), elevated LDL-C increases the risk of NAFLD. Conclusions. Our results revealed sex, age, and BMI modulate the association of physical examinations and blood biochemistry parameters and NAFLD, which may facilitate the development of personalized early warning and prevention strategies of NAFLD for at-risk populations.

The aim of this study was to examine the positions of newly erupted lower permanent incisors and their relationship to crowding. Forty-one crowded and 37 uncrowded dental casts of children in the early mixed dentition were examined by means of digitization using a reflex microscope. Two aspects of alignment were considered: rotation and labio-lingual displacement. Rotations of the incisors were defined as deviations from ‘ideal’ predicted angles. Displacement of the incisors was measured as the distance between the most labial and most lingually placed incisors. The study showed an increase in rotations amongst the crowded sample. The result of the investigation of the relationship between crowding and displacement was inconclusive. There would appear to be significant differences between the positions of newly erupted crowded and uncrowded incisors. Crowding, however, was not the only factor causing irregularity.

The purpose of this paper is to provide insight into the role of reward-based crowdfunding in farm financing, with a focus on its likelihood of success. The study uses a sample of 1,566 projects from the Kickstarter platform between 2014 and 2020. We added the level of urbanisation and relative importance of agriculture in the country's economy to the basic elements to assess the importance of the crowdfunding. We run a logistic regression model to investigate factors that motivate investment decisions. We discovered a statistically significant negative correlation between the self-set campaign goal and project success, as well as a small positive impact of number of backers and a positive impact of the importance of agriculture in the country's economy on crowdfunding success. In an era of rapid innovation and the rise of social networks, this paper contributes to the current literature on the agri-food industry's reword-based crowdfunding approach.
