RESUMO
Objective@#To analyze the blood pressure changes of adults aged 18-59 years in rural area of Shanxi province based on a cohort study, and provide reference for the study of the blood pressure level of rural residents and hypertension prevention and control in rural areas in China.@*Methods@#Data were obtained from Shanxi Nutrition and Chronic Disease Family Cohort from 2002 to 2015. Subjects aged <18 years or ≥60 years and individuals with hypertension at baseline survey in 2002, and those who had taken antihypertensive drugs for nearly two weeks during the follow-up survey in 2015 were excluded from the study. A total of 1 629 subjects aged 18-59 years were included in the analyses of the blood pressure level and its change from the baseline survey in 2002 to follow-up survey in 2015.@*Results@#The systolic blood pressure (SBP) of the subjects increased from (122.7±10.4) mmHg in 2002 to (132.8±17.6) mmHg in 2015 and the diastolic pressure (DBP) increased from (72.7±6.9) mmHg in 2002 to (78.8±10.3) mmHg in 2015. The SBP in men and women increased with growth rates of 6.7% and 9.5%. While DBP in men and women increased with growth rates of 9.3% and 7.8%. The SBP levels of those aged 18-, 30-, 40- and 50-59 years increased with growth rates of 5.0%, 6.7%, 9.4% and 11.8%. While the DBP of these age groups increased with growth rates of 12.2%, 8.2%, 8.2% and 6.5%.@*Conclusions@#The blood pressure of adults aged 18-59 years old in rural area of Shanxi showed a substantially increasing trend. The mean increase level of SBP in women was higher than that in men, and increased with age. While the mean increase level of DBP in men is higher than that in women, and decreased with age.
RESUMO
Objective@#To explore the association between dietary pattern which benefit for normal kidney function and the risk of cognitive decline or impairment in the elderly.@*Methods@#In 2015, subjects aged 60 and over from four counties in the Nutrition and Chronic Disease Family Cohort project, were followed up in 2017. Cognitive function was repeatedly assessed, using the Mini Mental State Evaluation (MMSE) scale. Dietary pattern that benefit for normal kidney function was extracted, using the reduced rank regression method and followed by logistic regression models to explore the associations between scores that showing the kidney function on dietary patterns and the risk of cognitive deterioration and impairment in two years among those who were with normal cognition in 2015.@*Results@#Dietary pattern that benefit for normal kidney function, was characterized by high consumption of cereal, vegetables, legume and fruits but with less meat and soy products. Comparing with the group with lowest score quartile on this dietary pattern, the risk of cognitive deterioration in the highest quartile group was significantly low (P<0.01) in two years, with an odds ratio as 0.57 (95%CI: 0.37-0.85). Linear trend was also obviously visible (P=0.007) in this group. The ones at the highest quartile group among the normal cognition ones in 2015, the risk of cognitive impairment also significantly reduced (P<0.05) in two years time, with an odds ratio as 0.52 (95%CI: 0.29-0.93). Also, linear trend could obviously be seen (P=0.01).@*Conclusion@#Dietary pattern that benefit for normal kidney function was both inversely associated with cognitive deterioration and impairment, in two years.
RESUMO
Objective To study the association between blood pressure related dietary pattern and cognitive impairment in the elderly.Methods In 2015,all participants who were aged ≥60 and participated in the Nutrition and Chronic disease family cohort were involved in the study.Information on demographic variables,lifestyle and health status was collected.Cognitive performance was assessed by the Mini Mental State Evaluation (MMSE) scale.Blood pressure,height and weight were measured by trained medical personnel and fasting venous blood samples were collected for testing on serum level of triglycerides and total cholesterol.Both SBP and DBP were used as response variables when dietary patterns were identified by reduced rank regression method.Logistic regression models were fit to explore the associations of scores on blood pressure-related dietary pattern and cognitive impairment.Results Two blood related dietary patterns were identified.The first one was characterized by high consumption of vegetables and less meat,eggs and dessert (Pattern 1),while the second one was with high consumption of meat,soy products,wine and fried foods and less intake of dairy (Pattem 2).Data showed that the Pattern 1 was associated with the risk of cognitive impairment.Comparing with the lowest quartile of score of this dietary pattern,the risk of cognitive impairment in the highest quartile group showed a significant (P＜0.01) increase,with OR=1.94 (1.21-3.11) and showing significant (P=0.002) linear trend.However,no significant association was observed (P＞ 0.05) with cognitive impairment in the second dietary pattern.Conclusion Blood pressure-related dietary pattern was positively associated with cognitive impairment.

RESUMO
Objective@#This study was to analyze the association of lipid parameters with insulin resistance of Chinese elderly population in different glycemic status.@*Methods@#Data were from China National Chronic Diseases and Nutrition Survey (2015). A total of 15 535 participants aged 60 and above who had completed survey questionnaire, physical examination, fasting blood biochemistry and insulin measurements were included in this study. According to the American Diabetes Association (2010) criteria, the participants were divided into normal glucose regulation, pre-diabetes, newly-diagnosed diabetes and previously-diagnosed diabetes. Multivariable logistic regression was preformed to assess the effects of lipid parameters on insulin resistance in different glycemic among the elderly population.@*Results@#The proportion of normal glucose regulation, pre-diabetes, newly-diagnosed diabetes and previously-diagnosed diabetes was 50.46% (n=7 839), 22.19% (n=3 448), 12.46% (n=1 937) and 14.88% (n=2 311), respectively. The risk of insulin resistance increased with the elevated per quartile of triglycerides (TG) (OR=1.48,95%CI: 1.35-1.62), non-high-density lipoprotein cholesterol (Non-HDL)/HDL-C (OR=1.23, 95%CI: 1.12-1.35) and TG/HDL-C (OR=1.50, 95%CI: 1.36-1.65) and decreased with the elevated per quartile of HDL-C (OR=0.83, 95%CI: 0.76-0.90) after multivariate adjustment among normal glucose regulation participants. As for pre-diabetes participants, the risk of insulin resistance increased with the elevated per quartile of TG (OR=1.26, 95%CI: 1.14-1.39) and TG/HDL-C (OR=1.38, 95%CI: 1.24-1.54) and decreased with the elevated per quartile of HDL-C (OR=0.79, 95%CI: 0.71-0.87). The risk of insulin resistance increased with the elevated per quartiles of TG/HDL-C (OR=1.29, 95%CI: 1.12-1.48) among newly-diagnosed diabetes. As for previously-diagnosed diabetes, the risk of insulin resistance increased with the elevated per quartile of TG, Non-HDL/HDL-C and TG/HDL-C with adjusted OR(95%CI) about 1.28 (1.16-1.41), 1.37(1.21-1.55) and 1.51 (1.33-1.72) repsectivley and decreased with the elevated per quartile of HDL-C (OR=0.77, 95%CI: 0.67-0.87).@*Conclusion@#The relationship between lipid parameters and insulin resistance presented diversely in different glycemic status. The elderly with normal glucose regulation and previously-diagnosed diabetes should pay close attention to the change of TG/HDL-C, TG, HDL-C and Non-HDL/HDL-C. As for prediabetes participants, the TG/HDL-C, TG and HDL-C level change should be focused.
