The detection rate was calculated, and the dynamic changes of the disease was analyzed macroscopically.Results:From 2016 to 2020, a total of 1 816 children aged 7 - 12 years were clinically examined in Shandong Province, and no child with KBD was found. A total of 1 224 children were examined by X-ray, among which 1 positive patient was found in 2016 and 2017, respectively, both of whom were metaphyseal changes, with a total detection rate of 0.16%. There were 367 adult patients with KBD in Shandong Province, including 304 patients with grade Ⅰ, 47 patients with grade Ⅱ and 16 patients with grade Ⅲ. All villages in the KBD areas in Shandong Province had reached the elimination standard, with the elimination rate of 100%.Conclusion:No clinical case of KBD is detected in children aged 7 - 12 years in Shandong Province from 2016 to 2020, which has reached the elimination standard and is in a continuous elimination state.
ABSTRACT
Objective@#To understand the current situation of snack consumption among children and adolescents in China and its relationship with overweight and obesity, so as to provide a basis for formulating strategies of preventing and controlling overweight and obesity in children and adolescents in China.@*Methods@#A total of 1 882 children and adolescents aged 6-17 years old, choosed from 15 provinces, autonomous regions and municipalities according to China Health and Nutrition Survey in 2018, were selected. Snack consumption was investigated by the 24 hour dietary retrospective method for three consecutive days. The pattern of snack consumption was explored by cluster analysis, and the relationship between snack consumption and overweight and obesity was analyzed by Logistic regression.@*Results@#The snack consumption rate was 60.6%, and the percentage of daily energy intake from snacks was 2.4%. Snack consumption characteristics could be divided into four modes. Mode 1 was characterized by daily intake of medium amount of fruit, Mode 2 was characterized by daily intake of small amount of fruit and baked goods, Mode 3 was characterized by daily intake of small amount of fruit, and Mode 4 was characterized by daily intake of medium amount of milk and small amount of fruit. After adjusting the relevant covariates such as energy intake, compared with those who did not eat snacks, the OR (95% CI ) values of the risk of overweight and obesity in different snack consumption patterns were 1.56(0.93- 2.58 ), 0.81( 0.51- 1.24), 1.24(0.94-1.63) and 1.00(0.60-1.63), respectively; the OR (95% CI ) values of percentage of daily energy intake from snacks from low to high quartiles were 1.17(0.81-1.68), 1.32(0.92-1.89), 1.12(0.77-1.61) and 1.00(0.69-1.45), respectively. There was no statistically significant difference( P >0.05).@*Conclusion@#The proportion of Chinese children and adolescents consuming snacks is relatively high, mainly including fruit and its products, milk and its products and baked goods. No association between snack consumption and overweight and obesity has been found.
ABSTRACT
Objective:To dynamically monitor the prevalence and trend of dental fluorosis in children in Shandong Province, and to evaluate the prevention and control measures for drinking water-borne endemic fluorosis (referred to as drinking water-borne fluorosis), and to provide scientific basis for the next step.Methods:Totally 40 counties (cities, districts) were selected as project counties (cities, districts) from drinking water-borne fluorosis areas in Shandong Province in 2018, and all counties (cities, districts) were selected in 2019 and 2020, to investigate the situation of water improvement, detect water fluoride content, and investigate the prevalence of dental fluorosis in children aged 8 - 12 years.Results:From 2018 to 2020, the detection rates of dental fluorosis in children aged 8 - 12 years were 10.30% (503/4 884), 8.94% (25 895/289 539) and 8.66% (24 061/277 689), respectively, with statistically significant differences (χ 2 = 27.10, P < 0.001), and the dental fluorosis indexes were 0.21, 0.18 and 0.17, respectively. The total detection rates of dental fluorosis in children of different age groups in the 3 years were 7.26% (6 590/90 775), 7.97% (9 303/116 680), 9.29% (12 167/130 915), 9.29% (12 238/131 670) and 9.95% (10 161/102 072), the differences were statistically significant (χ 2 = 615.71, P < 0.001). In the 3 years, the total detection rate of dental fluorosis was 8.93% (28 101/314 737) in boys and 8.69% (22 358/257 375) in girls, the difference was statistically significant (χ 2 = 10.27, P = 0.001). In 2018 and 2019, the detection rates of dental fluorosis of children aged 8 - 12 years in water fluoride qualified villages [5.74% (235/4 095) and 7.98% (20 200/253 082)] were significantly lower than those in villages with excessive water fluoride [33.97% (268/789) and 15.62% (5 695/36 457), χ 2 = 570.61, 2 283.76, P < 0.001]. Conclusions:The prevalence of dental fluorosis among children aged 8 - 12 years has been effectively controlled, and remarkable results have been achieved in prevention and treatment of drinking water-borne fluorosis in Shandong Province. However, the detection rate of dental fluorosis among children in a few endemic villages is high, so it is necessary to continue to strengthen the monitoring of fluoride content in drinking water and the condition of dental fluorosis among children.
ABSTRACT
Objective:To evaluate the effect of health education of a three-year special action for prevention and control of drinking water-borne endemic fluorosis (referred to as drinking water-borne fluorosis) in Shandong Province, and to provide basis for formulating health education measures in the next step.Methods:Nineteen of the disease affected counties (cities and districts) were selected as project counties (cities and districts) in key areas for prevention and control of drinking water-borne fluorosis in Shandong Province in 2018, and 50 disease affected counties (cities and districts) were selected in 2019, and the project counties (cities and districts) were expanded to all of the 105 disease affected counties (cities and districts) in Shandong Province in 2020. Three disease affected townships (towns) were selected in each county (city and district), and health education activities on drinking water-borne fluorosis were carried out in Grade 4 to Grade 6 of the central primary schools and the three villages under its jurisdiction. Students and housewives were selected to conduct questionnaire surveys on prevention and control knowledge of drinking water-borne fluorosis before and after health education. The incidence of dental fluorosis among children aged 8 - 12 years was investigated annually in 6 villages (with children aged 8 - 12 years > 50) , where health education activity was implemented and the incidence of dental fluorosis among children was > 30%, water fluoride content was > 1.5 mg/L and water improvement time was < 5 years.Results:After health education, the awareness rates of drinking water-borne fluorosis in fifth grade pupils [92.46% (4 571/4 944) vs 65.80% (3 334/5 067) in 2018; 94.84% (12 897/13 599) vs 73.55% (9 993/13 587) in 2019; 95.59% (30 407/ 31 809) vs 77.52% (24 463/31 557) in 2020] and housewives [94.12% (2 400/2 550) vs 76.04% (1 939/2 550) in 2018; 94.99% (6 412/6 750) vs 72.00% (4 860/6 750) in 2019; 95.53% (16 183/16 941) vs 78.43% (12 971/16 539) in 2020] were significantly improved (χ 2 = 1 070.47, 2 315.27, 4 456.40, 328.25, 1 294.80, 2 174.63, P < 0.05). After health education in 2020, there were significant differences in the correct answer rates of epidemic causes, hazards and preventive measures of drinking water-borne fluorosis in the questionnaire of fifth grade pupils and housewives (χ 2 = 390.78, 164.94, P < 0.05). The awareness rates of drinking water-borne fluorosis in fifth grade pupils and housewives in the eastern region (Qingdao City, Yantai City and Weifang City) were significantly higher than those in the western region (Dezhou City, Liaocheng City and Heze City) before health education (χ 2 = 547.43, 210.12, P < 0.05), and after health education, the awareness rates increased to more than 90%. The detection rate of dental fluorosis in children decreased year by year (χ 2trend = 27.95, P < 0.05). Conclusions:Through implementation of a three-year special action for prevention and control of drinking water-borne fluorosis in Shandong Province, the awareness rate of fluorosis among target populations has been significantly improved. However, it is still necessary for government departments to further increase investment in health education and carry out health education activities in a deep-going way.
ABSTRACT
Few studies have described the key features and prognostic roles of lung microbiota in patients with severe community-acquired pneumonia (SCAP). We prospectively enrolled consecutive SCAP patients admitted to ICU. Bronchoscopy was performed at bedside within 48 h of ICU admission, and 16S rRNA gene sequencing was applied to the collected bronchoalveolar lavage fluid. The primary outcome was clinical improvements defined as a decrease of 2 categories and above on a 7-category ordinal scale within 14 days following bronchoscopy. Sixty-seven patients were included. Multivariable permutational multivariate analysis of variance found that positive bacteria lab test results had the strongest independent association with lung microbiota (R2 = 0.033; P = 0.018), followed by acute kidney injury (AKI; R2 = 0.032; P = 0.011) and plasma MIP-1β level (R2 = 0.027; P = 0.044). Random forest identified that the families Prevotellaceae, Moraxellaceae, and Staphylococcaceae were the biomarkers related to the positive bacteria lab test results. Multivariable Cox regression showed that the increase in α-diversity and the abundance of the families Prevotellaceae and Actinomycetaceae were associated with clinical improvements. The positive bacteria lab test results, AKI, and plasma MIP-1β level were associated with patients' lung microbiota composition on ICU admission. The families Prevotellaceae and Actinomycetaceae on admission predicted clinical improvements.

Objective:The clinical features, laboratory indices, and imaging data of patients with Pneumocystis jirovecii pneumonia (PJP) were described and analyzed, aiming to provide helpful information for the diagnosis and treatment of PJP. Methods:A retrospective study were conducted with data from 154 PJP patients who visited China-Japan Friendship Hospital from May 2017 to August 2020. Their clinical characteristics, laboratory and imaging data, and clinical outcomes were collected for analysis. The patients were further divided into the death group (51 cases) and the survival group(103 cases). The differences between the groups were compared by using t-test, nonparametric test, and chi-square test. Results:Of the 154 PJP patients, there were 89 males and 65 females, with a mean age of (53.7±14.8) years. Among them, 85.7% (132/154) were on immunosuppressive/glucocorticoids agents within the past month. Besides, 27.9% (43/154) and 33.1% (51/154) had kidney diseases and connective tissue diseases, respectively. The major clinical manifestations in these patients involved fever 82.9% (126/154), cough 59.7% (92/154), and dyspnea 52.6% (81/154). For the laboratory data, the lactate dehydrogenase (LDH) was 561.0 (434.3, 749.0) IU/L and the value increased in 91.3% (95/104) of the patients. The CD4+T-cell lymphocytes in 88.0% (95/108) and 57.4% (62/108) of patients were lower than 400/μl and 200/μl, respectively. Furthermore, (1, 3)-β-D glucan (BG) increased in 74.4% (67/90) of PJP patients (≥100.0 ng/L). For the imaging results, chest computed tomography (CT) showed diffuse ground-glass shadows/grid shadows in 90% (117/130) patients. Compared with the survival group, higher LDH [690.5 (528.8, 932.3) IU/L vs 502.5 (381.8, 657.0) IU/L, Z=-3.375, P=0.001], white blood cell count (WBC) [9.8 (5.8, 12.6) ×10 9/L vs 7.3 (5.0, 10.1) ×10 9/L, Z=-2.392, P=0.017], and age [(69.8±14.5) years vs (50.6±14.0) years, t=-3.756, P=0.001] were found in the death group. Lower lymphocyte ratio [5.3 (3.2, 9.3) % vs 9.6 (5.6, 17.2) %, Z=?3.262, P=0.001] and oxygen partial pressure (PaO 2) levels [(73.2±20.5) mmHg vs (64.8±17.7) mmHg (1 mmHg=0.133 kPa), t=2.345, P=0.021] were also observed in the death group. Furthermore, in the death group, the bacterial and fungal infection rate was higher than the rates in the survival group [55.1% (27/51) vs 21.5% (22/103), χ 2=15.372, P=0.001]. Conclusions:Long-term use of immunosuppressive agents or glucocorticoids predispose to PJP. CD4+T-lymphocytes, LDH, and BG might be used as important auxiliary examinations for PJP patients. Age, LDH, WBC, lymphocyte ratio, PaO 2 and possible combinations with bacterial or fungal infections are more closely related to the prognostic of PJP patients.
ABSTRACT
Objective:To investigate the level and significance of CD4 + CD25 + Foxp3 + Treg in peripheral blood of patients with type 2 diabetes mellitus (T2DM) peripheral neuropathy. Methods:160 patients with T2DM (T2DM group) treated in Yancheng First People's Hospital from January 2018 to March 2019 were selected, including 54 patients with peripheral neuropathy and 106 patients without peripheral neuropathy. At the same time, 160 healthy people were selected as the control group to detect the levels of CD4 + CD25 + Foxp3 + Treg and 25-(OH)D 3 in peripheral blood. Pearson correlation analysis was used to analyze the correlation between CD4 + CD25 + Foxp3 + Treg in peripheral blood and other indexes. The receiver operating characteristic (ROC) value curve was used to analyze the predictive value of CD4 + CD25 + Foxp3 + Treg in peripheral blood of type 2 diabetic peripheral neuropathy. Results:The ratio of CD4 + CD25 + Foxp3 + Treg in T2DM group was (7.82±1.03)%, which was significantly lower than that in control group [(15.53±3.82)%, P<0.05]; The duration of T2DM patients with peripheral neuropathy was (7.71±1.18)years, which was significantly longer than that without peripheral neuropathy ( P<0.05), while the proportions of 25-(OH)D 3 and CD4 + CD25 + Foxp3 + Treg were (49.88±12.27)mmol/L and (5.88±1.20)% respectively, which were significantly lower than that without peripheral neuropathy ( P<0.05); Patients with peripheral neuropathy in group T2DM had significantly higher Michigan Diabetic Neuropathy Scores (MDNS) than that in patients without peripheral neuropathy [(14.82±2.01) vs (4.41±0.43), P<0.05]. The CD4 + CD25 + Foxp3 + Treg was positively correlated with 25-(OH)D 3 ( r=0.367, P<0.05), and negatively correlated with MDNS ( r=-0.398, P<0.05); the CD4 + CD25 + Foxp3 + Treg predicted that the area under the ROC curve of T2DM patients with peripheral neuropathy was 0.822, the cut-off value was 6.50%, and the sensitivity and specificity were 80.00% and 72.00% respectively. Conclusions:The level of CD4 + CD25 + Foxp3 + Treg in peripheral blood of T2DM patients decreased, which may play a role in the occurrence and development of peripheral neuropathy.

Objective@#To understand the malnutrition status and trends among children and adolescents, and to provide evidence for improving the nutritional status of children and adolescents in 9 provinces of China.@*Methods@#A total of 5 746 children and adolescents aged 7-17 years old from the "China Health and Nutrition Survey" in 2000, 2006, 2011, 2015 and 2018 were selected as the subjects. Variance analysis and Chi square test were used to analyze the BMI of children and adolescents with different characteristics and different types of malnutrition. Linear regression model was used to analyze the trends of BMI, stunting and wasting, and overweight and obesity in children and adolescents with different characteristics.@*Results@#From 2000 to 2018, the BMI of children and adolescents aged 7-17 increased from 17.66 kg/m 2 to 19.08 kg/m 2 ( F =22.88, P <0.05). The prevalence of overweight and obesity increased in both males and females( t =16.65,11.01, P <0.05). Comparison of the rates of wasting and Growth Retardation and overweight and obesity among children and adolescents aged 7-17 years in nine provinces in 2000, 2006,2 011, 2015 and 2018, the difference was statistically significant ( χ 2 wasting and grouth retardation =85.46, 29.55, 41.09, 29.86, 45.29; χ 2 overweight and obesity = 109.12 , 52.21, 98.23, 68.27, 52.49, P <0.05).@*Conclusion@#The prevalence of stunting and wasting of children and adolescents aged 7-17 in 9 provinces of China decreased. The prevalence of overweight and obesity showed an upward trend in 9 provinces of China. There were regional differences among the prevalence of stunting and wasting, as well as overweight and obesity. Active intervention strategies and measures should be taken to improve malnutrition and focus on the prevention of obesity in children and adolescents in China.
ABSTRACT
Objective:By exploring the source of children's total fluoride intake and the relationship between children's total fluoride intake and dental fluorosis prevalence, to calculate the benchmark dose (BMD) of children's total fluoride intake and its 95% confidence lower limit (BMDL), and to provide the basis for revision of "Total Fluoride Intake for Inhabitants" (WS/T 87-2016).Methods:The villages that had water improvement for 5 years and more in 6 provinces of Jiangsu, Shandong, Hebei, Anhui, Henan and Shaanxi were selected as survey sites in April 2014. The water fluoride content of these villages was 0.3 - 3.0 mg/L, tap water samples from the centralized water supply were collected, and fluoride content was detected by ion selective electrode method. Children aged 8 to 12 years were selected, children's dental fluorosis was checked by Dean's method. Children's dietary and drinking water volume were surveyed by duplicate portion study (measurement for 3 d), and dietary fluoride content was detected according to the "Method for Determination of Fluorine in Foods". The mean and standard deviation of drinking water fluoride intake, dietary fluoride intake, and total fluoride intake were measured. According to the dose-response relationship between children's total fluoride intake and the detection rate of dental fluorosis, BMD and BMDL were calculated, and the reference dose (RfD) was calculated based on BMDL.Results:The mean of water fluoride of all 29 villages was 1.26 mg/L (from 0.41 to 2.85 mg/L). Totally 3 043 children aged 8 to 12 years were checked, and the detection rate of dental fluorosis was 30.2% (919/3 034). The lowest detection rate of dental fluorosis was 2.0% (2/100) and the highest was 71.4% (30/42) in the 29 villages. The children's dietary and drinking water volume of 769 person-time aged 8 to 12 years were surveyed, the children's daily drinking water fluoride intake, dietary fluoride intake, and total fluoride intake were (0.83 ± 0.66), (1.13 ± 0.61) and (1.96 ± 0.89) mg/d, respectively. The BMD of children's daily total fluoride intake was 2.43 mg, the BMDL was 2.21 mg, and the RfD was 2.21 mg.Conclusion:The BMD of 8 to 12 years old children's daily total fluoride intake is the same as the allowable limit (2.4 mg) of the national standard "Total Fluoride Intake for Inhabitants" (WS/T 87-2016).
ABSTRACT
Objective:To master the current situation of prevention and control of drinking water-borne endemic fluorosis in Shandong Province, and to provide basic data for control and evaluation of drinking water-borne endemic fluorosis.Methods:From June to December 2019, in accordance with the requirements of the "National Drinking Water-Borne Fluorosis Monitoring Program (2019 Edition)" and "Shandong Province Drinking Water-Borne Fluorosis Monitoring Program (2019 Edition)", cross-sectional survey method was used to monitor the operation of the water supply projects, the fluorine content in drinking water, and the condition of children with dental fluorosis in all the disease affected villages of the drinking water-borne endemic fluorosis counties (cities, districts) in 16 cities of Shandong Province. Water fluorine was detected by "Standard Examination Methods for Drinking Water-Nonmetal Parameters" (GB/T 5750.5-2006), and in accordance with the "Standards for Drinking Water Quality" (GB 5749-2006), the water fluorine content was judged to be qualified or not. The examination and determination of dental fluorosis in children adopted "Diagnosis of Dental Fluorosis" (WS/T 208-2011), and the detection rate of dental fluorosis was calculated, the detection rates of dental fluorosis were compared between water improvement villages and villages without water improvement, qualified water fluorine and unqualified water fluorine villages.Results:There were 9 475 drinking water-borne endemic fluorosis villages in 105 counties (cities, districts) in Shandong Province, of which 9 370 were water improvement villages, and the water improvement rate was 98.89%. Among all the water improvement villages, there were 9 318 projects in normal operation, 45 intermittent projects and 7 scrapped projects. Among all the drinking water-borne endemic fluorosis villages, 8 254 villages were qualified in water fluorine, and the qualified rate of water fluorine was 87.11% (8 254/9 475); among water improvement villages, 8 210 villages were qualified in water fluorine, and the qualified rate of water fluorine was 87.62% (8 210/9 370); among the villages without water improvement, 44 villages were qualified in water fluorine, and the qualified rate of water fluorine was 41.90% (44/105). The qualified rate of water fluorine in water improvement village was significantly higher than that in villages without water improvement (χ 2 = 193.31, P < 0.05). The detection rates of dental fluorosis in children in water improvement villages and villages without water improvement were 8.92% (25 624/287 405) and 12.70% (271/2 134), respectively, and the detection rate of dental fluorosis in children in villages without water improvement was higher than that in water improvement villages (χ 2 = 37.23, P < 0.05). The detection rates of dental fluorosis in children in qualified water fluorine and unqualified water fluorine villages were 7.98% (20 200/253 082) and 15.62% (5 695/36 457), respectively, and the detection rate of dental fluorosis in children in unqualified water fluorine villages was higher than that in qualified water fluorine villages (χ 2 = 2 283.76, P < 0.05). Conclusions:Water improvement and fluorine reduction measures have been implemented in most drinking water-borne endemic fluorosis villages in Shandong Province, the detection rate of dental fluorosis in children in water improvement villages is lower than that in villages without water improvement. However, attention should be paid to the situation of water fluorine exceeding the standard and later management and maintenance to prevent the rebound of the disease.
ABSTRACT
Objective@#To understand the association between bullying and anxiety symptoms of boarding middle school students, and to provide a scientific basis for preventing bullying and promoting mental health of boarding middle school students.@*Methods@#By using stratified cluster random sampling method, 2 823 students were selected from 10 schools in Anyang, Henan Province. Questionnaire survey using self-designed bullying items and Mental Health Scale of Chinese Middle School Students was administered.@*Results@#The overall prevalence of school bullying was 37.9%， with boarding school students(38.9%) being higher than non-boarding school students (37.1%). The anxiety symptom reporting rate of boarding students (42.9%) was higher than that of non-boarding students (27.3%). Binary Logistic regression analysis showed that, compared with non-boarding students, bully victim and bully perpetuator/victim students were more likely to have anxiety symptoms (OR=2.30, 6.04，1.94, 4.23) (P<0.05).@*Conclusion@#There is a correlation between different roles of campus bullying and anxiety symptoms among boarding and non-boarding school students. Boarding school students have a higher risk of anxiety symptoms, especially among those with both experiences of bully perpetuator/victim.
ABSTRACT

ABSTRACT
Objective@#To explore the relationship between bullying among middle school students and family factors in a city of central China, so as to provide support for the prevention and reduction of school bullying among middle school students.@*Methods@#The stratified cluster random sampling method was used to investigate the bullying involvement and family factors of 2 996 middle school students from first grade in junior high school to third grade in high school in a city in central China. Chi-square test and Logistic-regression analysis were used to analyze the relationship between family factors and bullying participation of middle school students.@*Results@#Among 2 996 students, 390 students(13.0%) were found of having bullying behavior, and 1 127 students(37.6%) were found of being bullied. Univariate analysis showed that there were statistically significant differences in family factors such as whether she or he is the only child, father-child relationship, mother-child relationship, marital status of parents, whether the mother work away from hometown, education level of father and mother(χ2=8.88, 56.49, 30.85, 30.91, 3.89, 10.36, 11.72；25.00, 69.33, 46.76, 57.09, 3.93, 23.19, 45.49, P<0.05). Logistic regression analysis showed that the only child and mother’s education degree was junior college and below were the risk factors for middle school students’ bullying involvement (OR=1.37，1.39). Parents’ harmonious marital status and father’s not working outside are the protective factors of middle school students’ bullying(OR=0.53, 0.83).The only child is the risk factor of bullying in middle school students (OR=1.42), and good father relationship is the protective factor of bullying in middle school students (OR=0.38).@*Conclusion@#Family factors have a certain impact on the involvement of middle school students in bullying in a city of central China, and corresponding preventive measures should be formulated from the perspective of family to focus on the intervention of high-risk groups.
ABSTRACT
Objective To understand the implementation effects of control measures and the dynamic prevalence of drinking water-borne endemic fluorosis in Shandong Province.Methods From 2013 to 2017 in Shandong Province drinking water-borne endemic fluorosis areas,in accordance with the method of simple random sampling,10 monitored counties were selected,10 water fluorine decreasing projects were investigated of its running effect,and water fluoride was detected.In each monitored county,3 villages in the diseased areas were selected as fixed monitored villages.If the monitored village had changed its water,the operation of the project would be investigated.If the monitored village had not changed the water,one water sample would be collected according to 5 directions of east,west,south,north and middle to determine the water fluorine.All children aged from 8 to 12 in the village were also examined for dental fluorosis.X-ray fluorosis and urinary fluorosis in adults aged over 25 were detected in 2013 and 2017.Results From 2013 to 2017,in monitored counties,the normal operation rate of improved-water defluoridation projects was 99.19％ (368/371),the qualified rate of water fluoride content was 66.85％ (248/371).In 128 improved water projects,the normal operation rate was 100.00％ (128/128),the qualified rate of water fluoride content was 67.19％ (86/128).The average detection rate of dental fluorosis and community fluorosis index (CFI) in children aged 8-12 were 33.92％ (2 608/7 689) and 0.68 in all monitored counties from 2013 to 2017.The detection rate presented a declining trend year by year (x2 =152.47 P ＜ 0.01).The average detection rate and CFI in the villages with normal operation projects and qualified fluoride content were 26.10％ (1 311/5 023) and 0.47.The detection rate presented a declining trend year by year (x2 =207.67 P ＜ 0.01).The detection rate and CFI in the villages with water improvement projects under abnormal operation or excessive fluoride were 48.65％ (1 297/2 666) and 0.90.The detection rate of dental fluorosis in the villages with normal operation projects and qualified fluoride content was lower than the rate of the villages with water improvement projects under abnormal operation or excessive fluoride (x2 =193.98,P ＜ 0.01).In 2013 and 2017,X-ray detection rates of skeletal fluorosis in adults aged over 25 were 8.04％ (119/1 481) and 6.04％ (81/1 342),respectively.The adult urinary fluoride geometric mean values (1.24,1.49 mg/L) were lower than the normal limit of 1.6 mg/L both in qualified villages of water ffuoride content and exceeding-standard villages in 2017.Conclusions In Shandong Province,the effective water improvement has acquired some effects in control of drinking water-borne endemic fluorosis.But the water fluoride content of improved water defluoridation projects exceeds the national standard seriously and fluorosis has not been effectively controlled.
