ABSTRACT
BACKGROUND@#China has the largest elderly population in the world; little attention has been paid to the mental health of elderly in areas of extreme poverty. This is the first study to investigate the mental health of the rural elderly in poverty state counties in Chongqing and was part of the Chongqing 2018 health literacy promotion project.@*METHODS@#In 2019, a cross-sectional study was conducted to investigate the mental health status of the rural elderly in fourteen poverty state counties of Chongqing, in which a total of 1400 elderly aged ≥ 65 years were interviewed, where mental health status was measured by the ten-item Kessler10 (K10) scale. Ordered multivariate logistic regression was performed to evaluate the influencing factors related to mental health of the elderly in these areas.@*RESULTS@#The average score of K10 in 14 poverty state counties was 17.40 ± 6.31, 47.6% was labeled as good, 30.2% was moderate, 17.0% was poor, and lastly 5.1% was bad, and the mental health status of the elderly in the northeastern wing of Chongqing was better than the one in the southeastern wing of Chongqing. A worse self-rated health was the risk factor for mental health both in the northeastern and southeastern wings of Chongqing (all P < 0.001). Lower education level (OR (95% CI) = 1.45 (1.12-1.87), P = 0.004) was a risk factor in the northeastern wing, whereas older age (OR (95% CI) = 1.33 (1.13-1.56), P = 0.001) was a risk factors in the southeastern wing.@*CONCLUSIONS@#The results showed that mental health of the elderly in poverty state counties was poor, especially in the southeastern wing of Chongqing. Particular attention needs to be paid to the males who were less educated, older, and single; female with lower annual per capital income; and especially the elderly with poor self-rated health.

Objective To master the epidemic prevalence and the risk factors of brucellosis in animals and human,and to provide a basis for making prevention strategies and measures to brucellosis in Chongqing Municipality.Methods Qijiang and Wansheng district of Chongqing Munipality were selected as investigation points.Feeding status of goats in feedlots was investigated,and blood samples of goats were collected for laboratory testing.Epidemiological survey in employees on feedlots,family members closely exposed with goats,and other focus groups such as stockbreeding and veterinary was conducted,and blood samples was collected for laboratory testing according to the principle of informed consent.Clinical features of infested persons were investigated.Blood samples were screened by plate agglutination test (RBPT) and tube agglutination test (SAT).Results A total of 582 households in the two districts were investigated.The number of positive households was 40 households.The positive rate of the households was 6.87％.A total of 20 105 goat blood samples were tested.Of them,989 blood samples tested positive.The positive rate was 4.92％.A total of 337 blood samples of the risk population from 22 towns of the two districts were tested.Of them,45 samples were positive,and the positive rate was 13.35％.Eleven people were active patients of brucellosis.The epidemic sites were distributed in 16 towns,which accounted for 73.73％.The difference of the positive rates between the two districts was not significant (x2 =0.37,P ＞ 0.05).The positive rate of brucellosis among male and female was 11.57％ (28/242) and 17.89％ (17/95),respectively.The age of brucellosis infection distributed from 2 years old to 83 years old.One preschool child and 3 students were identified positive.The positive rate of brucellosis among feeder was the highest,which accounted for 31.75％ (40/125).The difference of positive rate of brucellosis among different professions was significant (x2 =63.40,P ＜ 0.05).Conclusions There is not a brucellosis case among animals or people reported in Chongqing non epidemic areas of brucellosis,but there are lots of infection.Surveillance and prevention of brucellosis should be strengthened in Chongqing.
ABSTRACT
Objective To evaluate the effects of prevention and control measures on coal-burning endemic fluorosis in Wulong County of Chongqing.Methods At a county level investigation,seven of the disease affected villages were investigated to evaluate the effectiveness of prevention and control measures on coal-burning endemic fluorosis in Wulong County from October 2012 to April 2013.Dental fluorosis of all children aged 8-12 was examined in every selected village.Urine samples of 50 children were collected and urinary iodine level was determined.The installed improved stoves,the drying of corn and pepper were investigated in every household surveyed.Ten samples of corn and pepper were collected and iodine level was determined.At a city level survey,seven of the disease affected villages were investigated to evaluate the effectiveness of prevention and control measures on coal-burning endemic fluorosis in April 2013.Dental fluorosis of all children aged 8-12 was examined in all villages.Ten households were selected for investigation of the installation of improved stoves,drying of corn and pepper.Children dental fluorosis was diagnosed based on the standard for Diagnosis of Dental FIuorosis (WS/T 208-2011).The fluoride concentration of children's urine was measured according to the standard for Urine-determination of Fluoride-ion Specific Electrode Method (WS/T 89-1996).The fluoride concentration of corn and pepper was measured by the method of fluoride-ion selective electrode.Results The field survey results at the county level showed that the prevalence rate of dental fluorosis of children aged 8-12 was 8.01％ (44/549).The qualified rate of installed improved stoves was 99.56％(3 186/3 200) and the rate of correct usage of improved stoves was 99.78％(3 179/3 186).The correct drying rates of corn and pepper were all 100.00％(2 390/2 390).Three hundred and fourteen urine samples were collected and the fluoride content was 0.25 mg/L.Fifty-eight corn and 58 pepper samples were collected.The fluoride contents of corn and pepper were 0.70,2.09 mg/kg,respectively.At the field survey at city level,seven of the disease affected villages were investigated,the prevalence rate of dental fluorosis of children was 11.28％ (38/337).Seventy households were surveyed for the improved stoves.The qualified rate of installation of improved stoves and the rate of correct usage of improved stoves were all 100.00％(70/70,70/70).The drying of 56 corn and 58 pepper samples was surveyed.The correct drying rates of corn and pepper were all 100.00％(56/56,58/58).Conchsion All villages have reached the elimination criteria of coal-burning endemic fluorosis areas in Wulong County.
ABSTRACT
Objective To explore the potential risk factors of schistosomiasis transmission so as to provide evidence for setting up the surveillance scheme of schistosomiasis prevention and control. Methods The schistosome infection of local inhabitants, mobile population and stock from endemic areas were investigated from 2002 to 2007 by using IHA or ELISA technique. The historical endemic reports of Chongqing City and the schistosomiasis cases, and the plants imported from schistosomiasis endemic areas and Oncomelania snails were investigated. The behavior of local inhabitants was also investigated. Results The investigated people included 5 112 local inhabitants, 1 455 mobile people from schistosomiasis endemic areas and 1 744 residents returned from the endemic areas. The sero-positive rates of them were 0.57%, 1.44% and 0.86%, respectively. Eighteen cases of imported schistosomiasis were found. There were many plants and stock imported from the schistosomiasis endemic areas. No imported snail was found. The farming of local inhabitants depended on the cattle chiefly. The rate of the harmless lavatories was 14.88%. The local residents had the habit of water contact. Conclusion There are potential risk factors for schistosomiasis transmission in the Three Gorges Reservoir areas. The local residents have potential risk behavior of getting infection of Schistosoma japonicum. The surveillance should be emphasized on the mobile population, imported plants and stock from endemic areas.
ABSTRACT
Objective To understand the correlative factors of impacting schistosomiasis prevalence so as to provide the scientific evidence for drawing up the control project in Three Gorges Reservoir areas.Methods The report system of schistosomiasis was set up,and the cases were investigated.The population were screened by indirect haemagglutination test(IHA),and the serum-positive people were examined with Kato-Katz technique.The livestock and plants imported from the schistosomiasis endemic areas were investigated.Results Eighty-eight floating people returning from schistosomiasis endemic areas and 107 floating persons from endemic areas were investigated,and the serum positive rates were 1.14% and 1.87%,respectively.No schistosome eggs were found in stool examinations.There was no livestock and plant imported from schistosomiasis endemic areas.The production of local inhabitants depended on mainly cattle,and the river water contact was popular.Conclusions There are infection resources of schistosomiasis imported from endemic areas,which has a potential risk of schistosomiasis prevalence.
