Association between BMI and Dental Caries among School Children and Adolescents in Jiangsu Province, China / 生物医学与环境科学（英文）

Obesity and dental caries are increasing epidemics, especially among children and adolescents. This epidemiological observational cross-sectional study was conducted to assess the possible association between body mass index (BMI) and dental caries among 111,792 school children and adolescents in Jiangsu Province. We found that 13.14% participants of the study sample were overweight, and 7.37% were obese. The prevalence of dental caries was 12.95% in overweight and 7.89% in obese students. There were significant differences in caries prevalence by sex, region, age group, and BMI. Overweight and obesity statuses were associated with dental caries among the study population. BMI and dental caries present a continuous health problem. Thus, we recommend that oral health promotion be used for caries prevention and control.

Prevalence of Overweight and Obesity among Students Aged 7-22 Years in Jiangsu Province, China / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To report the prevalence and trend of overweight and obesity among students aged 7-22 years in Jiangsu, 2010 to 2013.</p><p><b>METHODS</b>This cross-sectional study was carried out as part of students physical fitness and health survey in Jiangsu province. A total of 255,581 subjects (50.03% males and 49.97% females) enrolled in 82 school and 10 universities in Jiangsu. Weights and heights were obtained for each subject and its body mass index (BMI) was calculated using the Chinese Working Group on Obesity in China (CWGO).</p><p><b>RESULTS</b>Anthropometric measurement including bodyweight, height, BMI and bust were significantly different between males in urban compared to females living rural areas (P<0.001). The total prevalence of overweight and obesity was 12.4% and 5.7%. Males had a significantly higher rate than in female's student. The prevalence of overweight and obesity by age groups was (14.5%, 10.3%) at age 7-11 years, (11.2%, 6.8%) at age 12-14 years, (11.7%, 3.1%) at age 15-17 years, and (11.4%, 2.3%) at age 18-22 years. By regions; the highest prevalence of overweight obesity reported in Taizhou (10%, 14.2%), Xuzhou (9.4%, 12.5%), and Nanjing (9.2%, 15.6%), respectively.</p><p><b>CONCLUSION</b>The finding declares that overweight and obesity are important health problems among students in Jiangsu Province. Early intervention programme are needed to address this problems.</p>

A research on the construction of an assessment index system to evaluate the implementation of health promotion in enterprises / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To establish an assessment index system to objectively evaluate the implementation of health promotion in enterprises.</p><p><b>METHODS</b>Multi-methods, which include the reviewing references, the summarizing results of preliminary studies, the interview with experts and employers, were used in developing attentative index framework and working out the consultative questionnaires. Then the improved Delphi Method was adopted in collecting ideas from 20 experts in China, and they scored the importance of every single index by two rounds of consultation. On the basis of these data, the indicators were added , deleted or modified according to concentration and distraction levels of expert ideas. The method of the percentile weighted coefficient was conducted to decide the weighing of assessment index.</p><p><b>RESULTS</b>The responding rates to the two rounds of questionnaires were 90.91% and 100.00% respectively. The overall specialist authoritative coefficient was 0.69, the coordination coefficient of all indicators was 0.623 (P <0.01),and the coordination coefficient of the four kinds of first-ranking indicators was 0.313, 0.625, 0.390, 0.563, respectively (P<0.01).Eventually, an assessment index system consisting of 4 first-ranking indicators and 10 sub-indicators which were further divided into 52 grade-three indicators was set up.</p><p><b>CONCLUSION</b>The assessment index system possesses good content validity, and the liability and typicality were recognized by experts. However, it should be applied and validated in practice.</p>

Vitamin D receptor genetic polymorphisms and tuberculosis among Chinese Han ethnic group / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>In epidemiological studies, tuberculosis (TB) appears intimately with vitamin D insufficiency whereas its relationship with vitamin D receptor (VDR) polymorphism caused by radical difference remains unspecified. This study aimed to investigate the relationship between vitamin D genetic polymorphism and tuberculosis in Han ethnic group.</p><p><b>METHODS</b>Meta-analysis was adopted in the synthetic quantitative analysis of documents home and abroad on the relationship between vitamin D genetic polymorphisms and tuberculosis, which were openly published during June 2000 to January 2010. Random effect model and fixed effect model analyses were used to calculate the incorporated odds ratio (OR) based on the heterogeneity test data.</p><p><b>RESULTS</b>A total of 6 eligible studies were included in this analysis. The FokI-ff genotype showed a significant marginal association (Fixed effect model: OR 1.91, 95%CI 1.44-2.52; Random effect model: OR 1.91, 95%CI 0.94-3.88), yet TaqI polymorphisms was not significantly related to TB.</p><p><b>CONCLUSION</b>The interaction between FoKI genotype polymorphism and TB observed demonstrates that vitamin D deficiency might exist as a risk factor during the development of TB in Han ethnic group and more evidences needed to validate the conclusion.</p>
