OBJECTIVE To investigate the relationship between dietary intake during the third trimester and preeclampsia. METHODS A case-control study with 1∶1 matching was performed. A total of 131 patients with preeclampsia hospitalized in the First Affiliated Hospital of Zhengzhou University from March 2016 to December 2016 were selected as the case group. According to age ±3 years and gestational age ±2 weeks, 131 pregnant women with normal blood pressure and no proteinuria in the hospital were randomly selected as the control group. The questionnaires of food frequency and gestational health risk factors in the past three months were conducted and the average daily intakes of various nutrients were calculated. Conditional Logistic regression was applied to analyze the data. RESULTS Multivariate conditional Logistic regression showed that pre-pregnancy body mass index(OR=1. 18, 95%CI 1. 08-2. 82) and gestational weight gain(OR=1. 51, 95%CI 1. 15-1. 97) were higher, while the intakes of red and/or yellow fruits(OR=0. 76, 95%CI 0. 60-0. 98), and dietary vitamin C(OR=0. 57, 95%CI 0. 33-0. 99) and folic acid(OR=0. 36, 95%CI 0. 18-0. 72) were lower in case group than that in control group(P<0. 05). CONCLUSION Higher pre-pregnancy body mass index and over gestational weight gain are the risk factors for pre-eclampsia. Appropriate increase of red and/or yellow fruit intake during pregnancy may be beneficial to prevent pre-eclampsia. Vitamin C and folic acid intake might be protective factors for pre-eclampsia. .

OBJECTIVE:To understand the prevalence trend of metabolic syndrome (MS) and the characteristics of its major related risk factors in some faculty members of a college in Zhengzhou city.METHODS:Taking a case control study to analyze the results from 3481 faculty members of Zhengzhou University, such as body mass index (BMI), blood pressure, blood sugar and blood lipids, based on the diagnostic criteria for MS proposed in 2004 by the Diabetes Subcommittee of Chinese Medical Association.RESULTS:The total prevalence rate of MS was 10.3% (358/3481), and increased with age (chi2 = 110.008, P < 0.05). The prevalence of MS was significantly higher in male 13.1% (255/1954) than that in female 6.7% (102/1527) (chi2 = 36.929, P < 0.05). The systolic and diastolic blood pressure, blood sugar and triglyceride of males were significantly higher than those of females (P < 0.05). The subjects suffered from obesity, hypertension and high blood lipids simultaneously is accounted for 48.3% in five MS types; most of them are male and over 50 years of age. Age, systolic blood pressure, diastolic blood pressure, body mass index, blood glucose and triglycerides are risk factors in the logisitic regression analysis, while high-density lipoprotein is a protective factor.CONCLUSION:The prevalence of MS in male faculty members was high. Age, sex, BMI, blood pressure, blood glucose and blood lipids are closely related with the prevalence of MS. Faculty members of over 50 years of age are predisposed to MS. More attention should be paid to the prevention and control of such kind of metabolic disorders.

随着社会经济的发展,零食消费在学龄儿童青少年中越来越普遍,指导学龄儿童青少年合理选择适量消费零食,使之成为正餐不足部分的补充显得十分重要,因此,我们分析了1993年以来"中国居民健康与营养调查"的4轮调查数据,对儿童青少年的零食消费行为进行了分析.

OBJECTIVE:To study the changes of vitamin nutritional status of residents in a high-risk area of esophageal cancer.METHODS:8 towns where nutrition survey had been done were selected, 2 villages were randomly selected from each town and 30 families were randomly selected per village. The blood and 4h burden urine samples were collected from subjects. The serum vitamin A, blood total ascorbic acid and glutathione reductase activition coefficient (AC) in red blood cell were determinde by using of trifluoroacetic acid colorimetry, 2, 4-dinitrophenylhydrazine colorimetric method and Sauberlich method respectively. The contents of vitamin B2 , reduction ascorbic acid and total ascorbic acid in 4h burden urine were measured by using of fluorescent pectrophotometry,2,6-Dichloro-N-(4-hydroxyphenyl)-1,4-benzoquinoneimine titrimetric method and 2,4-dinitrophenylhydrazine colorimetric method respectively. The results were analyzed and compared with those of in 1980, 1983 and 1984. The t-test or chi2-test was carried out.RESULTS:The level of serum retinal in residents living in Ren cun, Dongyao and Hejian is significantly higher than that of in 1982 (P < 0.01). The level of vitamin B2 in 4h burden urine in residents living in Yaocun, Rencun and Heshun are significantly higher than that of in 1982 or 1984 (P < 0.01). The number of ribflavin deficiency of population living in Dongyao, Hejian, Yaocun and Rencun are significantly lower than that of in 1982 or 1983 (P < 0.01) according to the content of 4h burden urine and glutathione reductase activation coefficient (AC) in red blood cell; the number of vitamin C deficiency of population living in Dongyao, Hejian,Yao cun, Ren cun and Heshun are significantly lower than that of in 1982 or 1983 (P < 0.01) according to blood total ascorbic acid and the ascorbic acid content of 4h-burden urine and.CONCLUSION:Vitamin nutritional status of residents in a high-risk area of esophageal cancer have been improved.

OBJECTIVE:To investigate the time trends of cancer mortality among residents in Kaifeng county, Henan province.METHODS:Data on cancer mortality from the vital registration system in Kaifeng county from 1988 to 2005 was analyzed. A total of 9543 death records (5974 males and 3567 females) due to malignant tumors were studied. A two-year-period age-specified standardized mortality rates were directly adjusted by the world standard population, and the annual percentage change (APC) of mortality were estimated by a linear logarithm regression.RESULTS:The crude cancer death rate for male was 95.09/100,000 and its age-standardized death rate was 117.41/100,000. While, the crude cancer death rate for female was 59.13/100,000 and the age-standardized death rate was 57.15/100,000. There was a significant growth tread for lung cancer (APC: 6.54%), liver cancer (5.07%) in males and breast cancer (7.04%) in females in the groups aged over 18. On the contrary, the decreasing treads for esophageal cancer in both of sexes (-7.09%, -13.53%) were also observed in this study. Meanwhile, there was no other significant changes in the trend, either in the tumor sites or mortality, was observed.CONCLUSION:In the past two decades, there has been a significant increasing trend for cancer mortality in Kaifeng county, of Henan Province. Hence, it is necessary to enhance epidemiological survey to identify risk factors at the earlier stages.
