Investigation on water fluoride content and water-improving defluoridation projects in endemic fluorosis areas in Jining City, Shandong Province in 2005 / 中国地方病学杂志

Objective To investigate water fluoride content and the current status of water-improving project in Jining,Shandong Province in 2005.Methods Water fluoride content and the status of water-lmprovlng project were havestigated in Bencheng Ditrict,Liangshan and Jiaxiang Couties of Jining City.The fluoride content in drinking warer was assessed by F-ion selective electrode.Results Water fluoride contents of 671 fluorosis villages were determined.One hundred and seventy villages had water fluoride content less than or equal to 1.00 mg/L(accounting for 25.34%)and 501 villages water fluoride content higher that 1.00 mg/L(accounting for 74.66%),with the highest being 11.33 mg/L.Four hundred and ninty.seven projects were surveyed,in which 161 Projects were discarded (accounting for 32.39%),334 projeets worked well(accounting for 67.20%),and 2 pmjects worked fitfully(accounting 0.40%).Two hundreds and eighty-one projects had water fluoride content≤1.00 ms/L and 55 projects had water fluofide cantent>1.00 mg/L(aceounting for 26.82%),with the highest being 4.28 ms/L.Conclusions The situation of endemic fluorosis control is still serious in Jining City.Countermeasures for endemic fluorosis must be carried out as sppm as possible and surveillance of water-improving and defluoridation projects must be strevIsthend.

Acceptance test of dringking water improving project in Xuchang, Pingdingshan and Nanyang in 2006 / 中国地方病学杂志

Objective To investigate the water quality and running status of the dringking water improving project in Xuchang,Pingdingshan and Nanyang,thus to provide basis for scientifically evaluating social effects.Methods Stratified sampling was used in the levels of counties and townships and villages,with the number of checked counties greater than or eaquel to half of the projected counties(13/24),the checked townships more than 40 percent of the projected townships(42/102),the checked villages greater than or eaquel to 30% of the projected villages(56/186).We listened their statement,reviewed the documents,examined carefully the water projects before we made the appraisal.Results More than 95%(129/136)of the projects had water quality reports,among which 90%(122/136)were provided by county level centers for disease prevention and control,75% (102/136) of water samples were collected by centers for disease prevention and control,80%(109/136)ofcounties organized an acceptance check-up group,92%(125/136)projects well preserved water source.Conclusions The dringking water improvement projeets in countryside are basically normal in terms of construction and management,the water supplied is qualified,so the expected goal is achieved.However,duties of each department are not explicit and the communication is inadequate,so collaboration should be reinforced.

A Study on the Factors Influencing Food Consumption by Food Frequency Questionnaire far the Middle Aged and Elderly Living in the Chonju Area / 대한지역사회영양학회지

This study was conducted to find the differences in food consumption frequency of the middle aged(male 20, female 50) and the elderly(male 15, female 15) living in Chonju in December, 1998 according to food habits, smoking, alcohol drinking and exercising habit, health status, and the levels of nutrition knowledge and attitude store. The foods frequently consumed among the subjects were kimchi(15.4/week), mixed rice(11.5/week), rice(7.6/week), vegetables in soup, jjigae and jorim(5.0/week), mandarins and oranges(5.e/week), and seasoned laver(4.3/week). There were several factors influencing food consumption patterns. These were age, regularity of meal times, the status of smoking, alcohol drinking and exercising, and the level of nutrition attitude. The elderly ate cooked rice more frequently, while the middle aged ate fish, especially blue fishes more frequently. The middle aged who had breakfast regularly ate milk and milk products, legumes and fruits frequently. Those who smoked seemed to eat less cereals and starches and fats, while those who didn't smoke ate more sugars. The alcohol drinking group also ate less fats and the exorcising group ate almost all of food groups frequently. The status of health showed to be related with food consumption patterns. The normal group in hemoglobin ate eggs more frequently than the anemia group and the high risk group in blood pressure ate almost all of food groups more frequently. The high level group for nutrition attitude score chose vegetables, fruits, and milk and milk products more frequently than the other groups. On the other hand, low level group for nutrition attitude score was apt to eat ramyun, ham-sausage, and carbonated beverages more frequently. Therefore, nutrition education to improve the food habits find to change nutrition attitude is necessary to promote health status anti mole attention should be taken to the high risk group in blood pressure to guide proper food and nutrition intakes.

Serum Lipids by Gender, Age and Lifestyle in Korean Adults / 대한지역사회영양학회지

The purpose of this study was to measure serum lipids concentrations by gender and age, and to investigated the relation of serum lipids levels to cigarette smoking alcohol intake exercise and menopausal status in Korean adults. The subjects consisted of 463 healthy adult(29- men and 173 women) volunteers who were visiting the health Promotion Center in the Asan Medical Center from July 1, 1994 to July 22, 1994 Subjects were ambulatory free-living people and aged 20- 80 years, Anthropometric measurement was performed and serum triglyceride(TG), HDL-cholesterol and total cholesterol(TChol) concentrations were measure by automatic system(Hitachi 736-40). Data on life styles were obtained using structured questionnaires issued by a trained interviewer, All data were statistically analyzed by PC-SAS(Version 6.04) Serum concentrations of triglyceride and total cholesterol was higher(p170 mg/dL and TChol>220 mg /dL) was 12.5% in men and 4.1% in women. The levels of serum triglyceride, total cholesterol and BMI increased with age in women. The distribution curves of serum triglyceride, total cholesterol and LDL-cholesterol of women were located in lower increased more rapidly with aging than in men, The distribution curves of BMI of women increased with aging after the thirties, The BMI of women was located in higher levels than of men in their sixties. The serum concentration of triglyceride and total cholesterol of male current-smokers and non-smokers were significantly(p<0.05) higher than those of ex-smokers. The concentrations triglyceride the male current0drinkers were higher(p<0.05) than those of male non-drinkers. In non-smokers and non-drinkers, serum TG concentration were lower (p<0.05) than those of current-smokers and current-drinkers. In exercisers, the serum triglyceride concentration was significantly(p<0.05) lower than in non-exercisers. In postmenopausal woman BMI and serum concentrations of TChol, TG and LDL-Chol were significantly by age and gender and smoking alcohol drinking, exercise and menopausal staus might be a better indicator to predict serum lipids in both genders.
