ABSTRACT

Objective@#We aimed to investigate and interpret the associations between socioeconomic factors and the prevalence, awareness, treatment, and control of hypertension at the provincial level in China.@*Methods@#A nationally and provincially representative sample of 179,059 adults from the China Chronic Disease and Nutrition Surveillance study in 2015-2016 was used to estimate hypertension burden. The spatial Durbin error model was fitted to investigate socioeconomic factors associated with hypertension indicators.@*Results@#Overall, it was estimated that 29.20% of the participants were hypertensive nationwide, among whom, 34.32% were aware of their condition, 27.69% had received antihypertensive treatment, and 7.81% had controlled their condition. Per capita gross domestic product (GDP) was associated with hypertension prevalence (coefficient: -2.95, 95% @*Conclusion@#Hypertension indicators were not only directly influenced by socioeconomic factors of local area but also indirectly affected by characteristics of geographical neighbors. Population-level strategies should involve optimizing supportive socioeconomic environment by integrating clinical care and public health services to decrease hypertension burden.

ABSTRACT

Objective@#To explore the association between soil selenium levels and the risk of diabetes in Chinese adults aged 35-74 years.@*Methods@#Data for this study were derived from the China Chronic Diseases and Behavioral Risk Factors Surveillance 2010 survey. Selenium concentrations in soil were obtained from the Atlas of Soil Environmental Background Values in China. A two-level binary logistic regression model was used to determine the association between soil selenium concentrations and the risk of diabetes, with participants nested within districts/counties.@*Results@#A total of 69,332 participants aged 35-74 years, from 158 districts/counties were included in the analysis. Concentrations of selenium in soil varied greatly across the 158 districts/counties, with a median concentration of 0.219 mg/kg ( : 0.185-0.248). The results showed that both Quartile 1 (0.119-0.185 mg/kg) and Quartile 4 (0.249-0.344 mg/kg) groups were positively associated with diabetes compared to a soil selenium concentration of 0.186-0.219 mg/kg (Quartile 2), crude odds ratios ( s) (95% ) were 1.227 (1.003-1.502) and 1.280 (1.048-1.563). The values were 0.045 and 0.013, for Quartile 1 and Quartile 4 groups, respectively. After adjusting for all confounding factors of interest, the Quartile 1 group became non-significant, and the Quartile 4 group had an adjusted (95% ) of 1.203 (1.018-1.421) relative to the reference group (Quartile 2), the values was 0.030. No significant results were seen for the Quartile 3 group (0.220-0.248 mg/kg) compared to the reference group.@*Conclusion@#Excessive selenium concentrations in soil could increase the risk of diabetes among Chinese adults aged 35-74 years.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the stress distribution induced by simulated intra-oral loads on ceramometal crowns with different length of shoulder porcelain in labial margins.</p><p><b>METHODS</b>Eighteen two-dimensional finite element models of the maxillary central incisor restored with ceramometal crowns were constructed which were designed with different labial terminal locations of metal coping. Different coping alloys and marginal designs were employed in the crown models. The stresses of porcelain veneers and adhesive layers in all models were estimated with different loading locations and angles.</p><p><b>RESULTS</b>Although coping alloys and marginal designs were different, the labial terminal locations of metal coping had no influence on the stress distribution of porcelain veneers and adhesive layers.</p><p><b>CONCLUSION</b>The coping design of short labial margin to add the length of shoulder porcelain of ceramometal restorations can be used clinically.</p>
