Plant-based dietary patterns and risk of esophageal cancer:A prospective cohort study spanning 17 years

Objective: Plant-based diets have multiple health benefits for cancers;however, little is known about the association between plant-based dietary patterns and esophageal cancer(EC).This study presents an investigation of the prospective associations among three predefined indices of plant-based dietary patterns and the risk of EC.Methods: We performed endoscopic screening for 15,709 participants aged 40-69 years from two high-risk areas of China from January 2005 to December 2009 and followed the cohort until December 31, 2022. The overall plant-based diet index(PDI), healthful plant-based diet index(h PDI), and unhealthful plant-based diet index(u PDI), were calculated using survey responses to assess dietary patterns. We applied Cox proportional hazard regression to estimate the multivariable hazard ratios(HRs) and 95% confidence intervals(95% CIs) of EC across 3plant-based diet indices and further stratified the analysis by subgroups.Results: The final study sample included 15,184 participants in the cohort. During a follow-up of 219,365person-years, 176 patients with EC were identified. When the highest quartile was compared with the lowest quartile, the pooled multivariable-adjusted HR of EC was 0.50(95% CI, 0.32-0.77) for h PDI. In addition, the HR per 10-point increase in the h PDI score was 0.42(95% CI, 0.27-0.66) for ECs. Conversely, u PDI was positively associated with the risk of EC, and the HR was 1.80(95% CI, 1.16-2.82). The HR per 10-point increase in the u PDI score was 1.90(95% CI, 1.26-2.88) for ECs. The associations between these scores and the risk of EC were consistent in most subgroups. These results remained robust in sensitivity analyses.Conclusions: A healthy plant-based dietary pattern was associated with a reduced risk of EC. Emphasizing the healthiness and quality of plant-based diets may be important for preventing the development of EC.

Mechanistic associations between dietary patterns and colorectal cancer

Colorectal cancer(CRC)is a common cancer with high morbidity and mortality rates.Its occurrence and development are determined by many factors,including genetics,the environment,lifestyle,and so on.The occurrence of CRC is often accompanied by changes in the intestinal microenvironment.Numerous studies have focused on the association between dietary patterns,dietary components,and CRC now.This article reviews five different dietary patterns:the Western diet,the Mediterranean diet,the ketogenic diet,the Dietary Approaches to Stop Hypertension diet,and fasting,and themechanistic associations between their food components and CRC.The finding can provide a reference for further studies on the association between different dietary patterns and CRC and will help clinicians formulate reasonable and feasible dietary interventions.

Association of Dietary Pattern during Pregnancy and Gestational Diabetes Mellitus： A Prospective Cohort Study in Northern China

Objective To examine the association of maternal dietary patterns during pregnancy with gestationa diabetes mellitus （GDM） in northern China. Methods The dietary intakes of pregnant women were recorded twice by 24-hour dietary recalls for three days prior to having been diagnosed with GDM, at 5-15 and 24-28 gestational weeks, respectively. GDM was diagnosed, and serum glycosylated hemoglobin （HbAlc） was measured at 24-28 weeks. Dietary patterns were assessed by factor analysis. The association of the dietary pattern with GDM and HbAlc was examined by multiple logistic models. Results Of 753 participants, 64 （8.5%） were diagnosed with GDM. Four dietary patterns were identified： Western pattern （dairy, baked/fried food and white meat）, traditional pattern （light-colored vegetables, fine grain, red meat and tubers）, mixed pattern （edible fungi, shrimp/shellfish and red meat） and prudent pattern （dark-colored vegetables and deep-sea fish）. Compared with the prudent pattern, both the Western pattern and the traditional pattern were associated with an increased risk of GDM （aOR = 4.40, 95% CI： 1.58-12.22; aOR = 4.88, 95% Ch 1.79-13.32） and a high level of HbAlc （aOR = 12.37, 95% Ch 1.47-103.91; aOR = 26.23, 95% CI： 2.54-270.74）. Compared to the lowest quartile （Q）, 0.3 of the Western pattern scores and Q3-Q4 of the traditional pattern scores were associated with a higher risk of GDM. Conclusion The consumption of the Western pattern or the traditional pattern during pregnancy may increase the risk of GDM.

Crosstalk between dietary patterns,obesity and nonalcoholic fatty liver disease

The prevalence of nonalcoholic fatty liver disease(NAFLD)is rising worldwide,paralleling the epidemic of obesity.The liver is a key organ for the metabolism of proteins,fats and carbohydrates.Various types of fats and carbohydrates in isocaloric diets differently influence fat accumulation in the liver parenchyma.Therefore,nutrition can manage hepatic and cardiometabolic complications of NAFLD.Even moderately reduced caloric intake,which leads to a weight loss of 5%-10%of initial body weight,is effective in improving liver steatosis and surrogate markers of liver disease status.Among dietary patterns,the Mediterranean diet mostly prevents the onset of NAFLD.Furthermore,this diet is also the most recommended for the treatment of NAFLD patients.However,clinical trials based on the dietary interventions in NAFLD patients are sparse.Since there are only a few studies examining dietary interventions in clinically advanced stages of NAFLD,such as active and fibrotic steatohepatitis,the optimal diet for patients in these stages of the disease must still be determined.In this narrative review,we aimed to critically summarize the associations between different dietary patterns,obesity and prevention/risk for NAFLD,to describe specific dietary interventions’impacts on liver steatosis in adults with NAFLD and to provide an updated overview of dietary recommendations that clinicians potentially need to apply in their daily practice.

Dietary Patterns Associated Metabolic Syndrome in Chinese Adults

Dietary pattern has been revealed to be associated with metabolic syndrome. However, the association was not well documented in Chinese due to the complexity of Chinese foods. We mainly assessed the dietary patterns and examined their effects on metabolic syndrome among Chinese adults. Four dietary patterns including ＇Refined Grains ＆ Vegetables＂ Pattern, ＇Dairy ＆ Eggs＇ Pattern, ＇Organ Meat ＆ Poultry＇ Pattern, and ＇Coarse Grains ＆ Beans＇ Pattern were extracted. ＇Dairy ＆ Eggs＇ Pattern was associated with a decreased odds of metabolic syndrome in women, and ＇Coarse Grains ＆ Beans＇ Pattern was associated with a decreased odds of hypertension in men. These results provided a scientific basis for future research and dietarv euideline Perfection.

Changes in Dietary Patterns and Certain Nutrition-related Diseases in Urban and Rural Residents of Jiangsu Province,China,During the 1990s

Objective To investigate into the changes of dietary patterns and their impacts on health of urban and rural residents in Jiangsu Province, China during the 1990s. Methods On the basis of the results of food consumption survey, the calorie intake was calculated according to the balanced diet method and the quality of diet was assessed by scores of desirable dietary pattern (DDP). Results It was found that food consumption and dietary patterns changed remarkably during the 1990s. Grain consumption was decreasing year by year, but the consumption of animal food was markedly increasing. Although the score of desirable dietary pattern (DDP) in urban residents was more than 90, the deducted score due to over-consumption of animal food increased. The mortality from infectious diseases evidently decreased in the whole province, while the death rates of some chronic diseases, such as diabetes, hypertension, colorectal cancer and breast cancer, were increasing rapidly in urban areas. Conclusions Sufficient attention should be paid to the negative effects of change in dietary patterns on people's health, especially in the urban residents.

COVID-19-associated stroke risk:Could nutrition and dietary patterns have a contributing role?

The novel coronavirus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus 2 has created a life-threatening world pandemic.Unfortunately,this disease can be worse in older patients or individuals with comorbidities,having dangerous consequences,including stroke.COVID-19–associated stroke widely increases the risk of death from COVID-19.In addition to the personal hygiene protocols and preventive policies,it has been proven that immune-compromised,oxidative,and pro-coagulant conditions make a person more susceptible to severe COVID-19 complications,such as stroke;one of the most effective and modifiable risk factors are poor nutritional status.Previous literature has shown that healthy dietary patterns,such as the Mediterranean diet,some food groups,and specific micronutrients,reduce the risk of ischemic and hemorrhagic stroke.In this work,for the first time,we hypothesized that a healthy diet could also be a protective/preventive factor against COVID-19–associated stroke risk.In order to prove this hypothesis,it is required to study nutritional intake and dietary patterns in patients suffering from COVID-19–associated stroke.If this hypothesis is proven,the chronic supportive role of a healthy diet in critical situations will be highlighted once again.

Meta-Analysis of the Breast Cancer Risk Associated with Three Dietary Patterns

Objectives A meta-analysis was conducted to assess the association between breast cancer risk and three common dietary patterns.Methods The PubMed,Web of Science,CNKI,Wanfang,Embase,and Cochrane Library databases were systematically searched(until June 2022)for studies on the association between three common dietary patterns,including the Western dietary pattern,vegetarian dietary pattern and Mediterranean dietary pattern,and the risk of breast cancer.The Newcastle-Ottawa(NOS)scale was used to assess study quality.Results A total of 24 articles published from 2001 to 2021 that met the criteria were included for meta-analysis.The Western dietary pattern was positively associated with the breast cancer risk in women both before and after menopause,although the heterogeneity in the study was high(HR=1.05,95%CI:1.01-1.30,I^(2)=56.2%,P=0.019).There was an inverse association between the vegetarian dietary pattern and breast cancer risk among women(HR=0.87,95%CI:0.78-0.97,I^(2)=73.7%,P<0.001).No association was observed between the Mediterranean dietary pattern and women's risk of breast cancer(HR=0.96,95%CI:0.89-1.02,I^(2)=64.1%,P=0.010).Due to the presence of significant heterogeneity among the studies,we performed a subgroup analysis,meta-regression analysis and sensitivity analysis,and found that factors such as the type of study design were the main sources of heterogeneity in each group.These results remained largely unchanged after excluding studies of a specific type from the sensitivity analysis.Conclusion The Western dietary pattern can increase the risk of breast cancer,while the vegetarian dietary pattern can reduce the risk of breast cancer.No association between the Mediterranean dietary pattern and the risk of breast cancer was observed.

Use of Desirable Dietary Pattern (DDP) for Study of Dietary Pattern in Urban and Rural Residents of Jiangsu

Objective To make retrospective assessment of the quality of diet in the urban and rural residents of Jiangsu province, China, during the 1990′s and a prospective study of the dietary pattern in the year of 2010 with desirable dietary pattern (DDP). Methods The calorie intake was calculated according to the method of balanced diet and the dietary pattern was assessed in terms of DDP score. Results Retrospective study revealed that the DDP score of cereals was decreased and that of animal foods increased remarkably in both the urban and rural residents during the decade. Prospective study showed that the readjustment of dietary structure for the urban residents should be focused on preventing the drop of cereal consumption and further lowering the intake of pork. Promotion of soybean and milk consumption to great extents will be needed to improve the quality of diet for both urban and rural residents of Jiangsu in the future. Conclusion It was illustrated that DDP is feasible for retrospective and prospective studies on dietary pattern as it is simple in calculation, its results are easy to understand and of practical significance to the masses and health workers.

Utilization effect of water-land resources under the evolution of Chinese dietary patterns

Exploring the utilization effect of water-land resources under the evolution of dietary patterns is of great significance in achieving sustainable global food consumption and the effective allocation of national resources.Our selected study area was China,a country with rapidly changing dietary consumption patterns,and the research period was between 1987 and 2020.Based on the material called Chinese Dietary Guidelines 2021,this study introduced the“virtual water”and the“virtual land”to quantify the utilization effect of water-land resources under the evolution of Chinese dietary patterns.Results showed that the dietary patterns gradually changed from“cereal-vegetable-based consumption”to“diversified consumption”.Food consumption’s total water footprint(WF)increased from 471.1 Gm3in 1987 to 848.8 Gm3in 2020,with a growth rate of 80.2%.Moreover,the total land requirement for food(LRF)increased from 88.8 Mha in 1987 to 129.9 Mha in 2020,with a growth rate of 46.3%.Furthermore,the meat consumption was the major contributor to the increase in total WF(104.0%)and LRF(102.1%).In contrast to the balanced diet pattern,there was no waste of water-land resources consumption for the food consumption of urban-rural residents in China between 1987 and 2020.However,the consumption of water resources would gradually approach the resource cost under the balanced diet patterns.It would eventually break through the critical value and reach the state of resource waste.In addition,the findings showed that urban residents’waste rate of water-land resources for meat consumption increased by 142.3%compared with that in 1987.The research results can provide scientific guidance for resolving the food crisis under the supply of water-land resources in China and have an essential reference for national food security and sustainable development of resources and environment.

Dietary pattern and hepatic lipid metabolism

The liver is the leading site for lipid metabolism,involving not only fatty acid beta-oxidation but also de novo synthesis of endogenous triglycerides and ketogenesis.The liver maintains systemic lipid homeostasis by regulating lipid synthesis,catabolism,and transportation.Dysregulation of hepatic lipid metabolism precipitates disorders,such as non-alcoholic fatty liver disease(NAFLD),affecting the whole body.Thus,comprehending and studying hepatic lipid metabolism is crucial for preventing and treating metabolic liver diseases.Traditionally,researchers have investigated the impact of a single nutrient on hepatic lipid metabolism.However,real-life dietary patterns encompass diverse nutrients rather than single components.In recent years,there have been increased studies and notable progress regarding the effects of distinct dietary patterns on hepatic lipid metabolism.This review summarizes the influence of diverse dietary patterns on hepatic lipid metabolism,elucidating underlying molecular mechanisms and appraising the therapeutic potential of dietary patterns in managing hepatic steatosis.

SHIFTING TO A RECOMMENDED DIETARY PATTERN COULD PROMOTE SUSTAINABLE DEVELOPMENT OF THE ENVIRONMENT AND HUMAN HEALTH

With the rapid development of China’s economy,Chinese people tend to eat foods rich in fat,sugar and protein.This change in dietary pattern has brought double challenges to China’s sustainable development of environment and human health.So it has become urgent for the nation to shift to a healthy and sustainable dietary pattern.Based on the China Health and Nutrition Survey database,this study used K-means cluster analysis to classify China’s existing dietary patterns into quasi-southern,quasi-northern and quasi-western patterns.Two alternative recommended dietary patterns,Chinese dietary and planet health patterns,were selected to compare the effects of environment and health.The results show that a shift from the three existing dietary patterns to two alternative dietary patterns could enhance sustainable development of environment,especially for the quasi-western pattern shifting to the planet health pattern.Also,a shift would have of great benefits for human health,effectively reduce the relative risks of diseases such as hypertension,type 2 diabetes and coronary heart disease.The greatest benefits would come from shifting the quasi-western pattern benefits to one of the two alternative dietary patterns in terms of environment effects,and the quasi-southern pattern benefits most in terms of health effects.Shifting to the planet health pattern is more effective than the Chinese dietary pattern both in environment and human health.This paper provides policy recommendations to vigorously advocate dietary balance,scientifically promote dietary patterns,and change consumer dietary behavior.

The effect of healthy dietary patterns on male semen quality:a systematic review and meta-analysis

The incidence of infertility has recently risen.Semen quality is an important male fertility indicator,and dietary factors can affect semen quality.We conducted this systematic review and meta-analysis to determine the effects of healthy dietary patterns on semen quality.A literature search was conducted in 3 databases(Embase,Web of Science and PubMed)on August 21,2021.The included cross-sectional studies examined the influence of the Mediterranean,Dietary Approaches to Stop Hypertension(DASH),and prudent diet patterns on semen quality parameters;six studies(1244 subjects)were included.By comparing high consumption with low consumption of healthy dietary patterns,the results of the meta-analysis showed significantly higher sperm concentrations(mean difference[MD]=6.88×10^(6) ml^(−1),95%confidence interval[CI]:1.26×10^(6) ml^(−1)–12.49×10^(6) ml^(−1);P<0.05),a significant increase in total sperm count(MD=16.70×10^(6),95%CI:2.37×10^(6)–31.03×10^(6);P<0.05),and a significant increase in progressive sperm motility(MD=5.85%,95%CI:2.59%–9.12%;P<0.01).The sperm concentration,progressive sperm motility,and total sperm count were significantly higher in men with higher versus lower consumption of healthy dietary patterns.However,the results must be interpreted with caution.

Heart failure symptom burden,dietary intake,and inflammation:An integrative review of the literature

Heart failure(HF)is characterized by high symptom burden including,but not limited to fatigue,dyspnea,and edema.Up to 21.5%of HF patients experience significant depressive symptoms,much higher than 7.1%in adults without HF.Diet,metabolites,and other inflammatory mechanisms have gained notable attention in recent studies for contributions to symptoms in HF.Symptoms for black adults(B/As)with HF are often influenced by lifestyle factors,which may influence their higher mortality rates;few studies address these factors.Distinguishing the links between key elements with diet,inflammation,and symptoms may bring clarity for new dietary strategies in HF clinical care.The purpose of this integrative review is to examine the existing literature regarding relationships among physiologic pathways in HF along with physical and emotional symptoms in the context of inflammation,dietary intake,tumor necrosis factor‑alpha(TNF‑a),a biomarker of inflammation,and trimethylamine‑N‑Oxide(TMAO).Based on available evidence,inflammation may be a key link between physical symptoms,diet,depression,TMAO,and TNF‑a in persons with HF and warrants further examination to clarify pathological links to solidify evidence for better guidance with dietary modifications.The literature reviewed in this study demonstrates that more work is needed to examine dietary planning,social support,and differences between men and women in the B/A community.Results of this literature review call attention to the essential,personalized care needs related to symptom monitoring and dietary planning which is expected to decrease symptom burden in the HF population.

The Patterns of Complementary Feeding and Growth among 12 to 23 Month-Old Children in China

Objective This study aimed to understand the characteristics of dietary patterns among children aged12 to 23 months and discusses the relationship between dietary patterns and the growth of children.Method Cross-sectional data were selected from the National Nutrition and Health Systematic Survey for 0 to 18 year-old children in China(n=2,449)to describe the patterns of complementary feeding and the growth of children.Cluster analysis was used to analyze complementary feeding patterns,and an analysis of variance and Bonferroni test were conducted to analyze the relationship between Z scores and complementary feeding patterns.Results Four dietary patterns were identified among the children via cluster analysis.In Pattern 4(n=104,4.2%),children still consumed milk as their staple food.They displayed the lowest grain,fruit,vegetable,egg,and flesh foods consumption,a medium frequency of breast milk consumption,and a high frequency of dairy product consumption.Pattern 4 had the lowest length-for-age Z scores and weight-for-age Z scores,with-0.10±1.34 and 0.24±1.00,respectively(F=7.940,P<0.001;F=5.317,P<0.001).Conclusion Although China is undergoing rapid urbanization and economic development,there is still a phenomenon of insufficient intake of protein-rich foods and dairy-based dietary patterns at the stage of complementary food introduced among children aged 12 to 23 months.

Dietary phytochemical consumption is inversely associated with liver alkaline phosphatase in Middle Eastern adults

BACKGROUND The hepatoprotective effects of phytochemicals are controversial.A dietary phytochemical index(DPI)has been suggested as an alternative method for quantifying the phytochemical content of foods.AIM To assess the DPI in relation to liver function tests among a representative sample of Iranian adults.METHODS A total of 5111 participants aged 35-70 years old were included in this cross-sectional study by a multistage cluster random sampling method.Dietary intakes were collected by a validated and reliable food frequency questionnaire with 121 items.DPI was calculated by the percent of daily energy intake taken from phytochemical-rich foods.Fasting serum concentrations of alanine aminotransferase(ALT),aspartate aminotransferase(AST),alkaline phosphatase(ALP)and gamma glutamyl transferase(GGT)were determined.Linear regression was used to investigate the association between DPI and levels of liver enzymes using crude and adjusted models.RESULTS There was an inverse association between DPI score and serum ALP in the crude model(β=-0.05;P<0.001).This association remained significant after adjustment for body mass index,age,smoking,energy intake,history of diabetes,and education(β=-0.03;P=0.01).No significant associations were found between DPI score and serum levels of AST,ALT,and GGT.The individuals with the highest DPI scores consumed significantly higher amounts of fruits,vegetables,legumes,nuts,and cereals,yet were shown to have significantly higher serum total cholesterol and low-density lipoprotein cholesterol,as well as several other metabolic abnormalities.CONCLUSION Higher adherence to phytochemical-rich foods was associated with lower levels of ALP,but no change in other liver enzymes.Those with higher DPI scores also consumed food items associated with a healthier overall dietary pattern;however,they also presented several unexpected metabolic derangements.Additional randomised trials are needed to better determine the effects of phytochemical-rich foods on liver function.

NaFeEDTA Fortified Soy Sauce Showed Higher Iron Absorption Rate in Chinese Females

Objective NaFeEDTA was considered as a promising iron fortificant for controlling iron deficiency anemia. Soy sauce is a suitable food carder for iron fortification and is a popular condiment in China. Iron absorption rates of NaFeEDTA and FeSO4 were observed and compared in adult female subjects. Methods The stable isotope tracer method was used in Chinese females consuming a typical Chinese diet. Ten healthy young Chinese women were selected as subjects in the 15-day study. A plant-based diet was used based on the dietary pattern of adult women in the 1992 National Nutrition Survey. Six milligram of 54Fe in 54FeSO4 soy sauce and 3 mg 5SFe in NaSSFeEDTA soy sauce were given to the same subjects in two days. Food samples and fecal samples were collected and analyzed. Results Iron absorption rates of NaFeEDTA and FeSO4 were 10.51%：~：2.83 and 4.73%＋2.15 respectively. The 5SFe （NaFeEDTA） absorption was significantly higher than that of 54Fe （FeSO4） （P〈0.01）. The iron absorption rate from NaFeEDTA was 1.2 times higher than that from FeSO4 in Chinese adult women consuming a typical Chinese diet. Conclusion The higher absorption rate of NaFeEDTA suggested that NaFeEDTA would be a better iron fortificant used in soy sauce for the controlling of iron deficiency anemia in China.

Beer, wine and lifestyle: a cross-sectional study of the Belgian military population

Background: A reduction in mortality associated with wine drinking compared to beer drinking has been suggested in the past. A recent meta-analysis could not confirm the observed differential effect. Other characteristics not related to specific components of beer and wine must play a role in the relationship between wine and mortality, thereby explaining the differential protective results.Methods: A military population was selected to investigate the lifestyle differences between beer and wine drinkers. A food-frequency questionnaire was used to register alcohol and food consumption, together with questionnaires for health-related and lifestyle characteristics. Three dietary patterns were characterized by the Healthy Eating Index 2010, the Mediterranean Diet Score and a pattern obtained by principal component analysis.Results: In the multivariate analysis, beer consumption decreased with increasing age, military rank, physical activity and dietary pattern scores. Beer consumption increased with total energy intake and with smoking.Conclusion: Wine consumption was associated with a healthier lifestyle compared with beer consumption. Those differences must be taken into account when relating types of alcoholic beverage consumption with health-related outcomes.

Nutritional Status and Virological Outcomes of Children HIV Positive Attending Anti-Retroviral Clinic at University College Hospital, Ibadan

Malnutrition has been reported as a major factor contributing to the poor outcome of effective ART in HIV infection. This study aimed to describe the relationship between the nutritional status and virological outcome of the children attending the antiretroviral clinic at University College Hospital (UCH) Ibadan, Nigeria. Among the 159 (55.3% males and 44.7% females) children studied, almost half (42.8%) were orphans and the majority 56.6% were aged 120 - 180 months old. More than half (74.2%) had achieved viral suppression and significant associations were observed between viral load and stunting as well as between CD4 count and the age of the children (P < 0.05). The prevalence of stunting, wasting, and underweight was 27.7%, 9.4%, and 13.6% respectively. These indices reinforce the need for nutrition education and the provision of food supplements to improve the nutritional status of children infected with HIV.

Prevalence and Risk Factors Associated with Prehypertension among Young and Middle-Aged Health Check-Up Population in Guangzhou

Objective:To provide basic information and theories for prehypertension early intervention,a systematic analysis of the epidemic status and risk factors among young and middle-aged was carried out here.Methods:This study relied on the data bank of a health check-up population of a class a tertiary general hospital in Guangdong province in 2015.Total 9540 young and middle-aged adults were enrolled,and 733 people were included to find out the effect with lifestyle in these crowd.Principal Components Analysis(PCA)of Factor(FA)was used to identify dietary patterns.The logistic regression model was used to find the risk factors of prehypertension.Results:Among 9540 young and middle-aged cases,the incidence of prehypertension was 36.6%.Moreover,the average age,proportion of male gender,overweight,FBG(fasting blood glucose),dyslipidemia,and hyperuricemia were significantly higher in the prehypertension group than in the optimal BP group.Multivariate logistic regression analysis indicated that age,total cholesterol,triglycerides,uric acid,body mass index and HR(heart rate)were risk factors,and female was a protective factor for prehypertension.Among 733 cases,the incidence of prehypertension was 35.1%.The proportion of smoking,drinking,physical workers,moderate and severe physical activity,and the intake of meat,dietary energy were significantly higher in the prehypertension group than in the optimal BP group.Dietary patterns included“meat model”,“spice model”,“main vegeTables model”and“high protein model”.Multivariate logistic regression analysis indicated that age,drinking were risk factors for prehypertension,while dietary milk intake,dietary magnesium intake were protective factors.Conclusions:Prehypertension is highly prevalent in Guangzhou.However,education about effective lifestyle modifications as an alcohol limit,increasing the intake of dairy products,and magnesium may intervene in the development of prehypertension.But how to develop targeted interventions for such groups need to be further explored.The present study would lay the theoretical foundation and basic data for the next step.
