Cadmium Intake, Dietary Patterns and Hyperuricemia Among Adults in China

Blood and urine cadmium levels have been found to be positively associated with hyperuricemia (HU) in some studies. Few studies have examined the association between dietary cadmium intake, dietary patterns and HU in the Chinese population. The study analysed data from 8429 adults who participated in the China Health and Nutrition Survey (CHNS). Dietary intake was assessed by 3-day 24 h food record in seven waves of survey (1991, 1993, 1997, 2000, 2004, 2006 and 2009). Serum uric acid was measured in 2009. Dietary pattern was identified using factor analysis. The association between cumulative dietary cadmium intake, dietary patterns and HU was assessed using logistic regression. In total, 1737 (16.3%) participants had HU in the study sample. After adjusting for demographic, lifestyle factors (i.e. smoking, alcohol drinking, physical activity) and chronic conditions, the OR for HU was 2.25 (95%CI 1.84–2.77, p for trend < 0.001) for extreme quartiles of estimated cumulative cadmium intake. A traditional southern dietary pattern characterized by high intake of rice, pork, fish and vegetables, and low intake of wheat was associated with three times increased prevalence of HU; comparing the extreme quartiles, the odds ratio (OR) was 3.24 (95%CI 2.61–4.01). No association between the modern dietary pattern (high intake of fruit, soymilk, egg, milk and deep fried products) and HU was found. In conclusion, traditional southern dietary pattern and cadmium intake are positively associated with hyperuricemia among Chinese adults.This research uses data from China Health and Nutrition Survey (CHNS).

Gut Microbiota: An Important Link between Western Diet and Chronic Diseases.

A Western diet characterised by high intake of energy-dense and processed food is a risk factor for many chronic diseases including diabetes, obesity and cardiovascular diseases [1]. Much of the research focus is on the high intake of fat, sugar, and low intake of fibre and fruits and vegetables [1]. One of the underlying mechanisms linking Western diet and chronic diseases is inflammation. A dietary inflammatory index has been proposed and tested to reflect the link between diet and inflammation in different populations

Chili Intake Is Inversely Associated With Chronic Kidney Disease Among Adults: A Population-Based Study

We aimed to assess the association between chili consumption and kidney function and chronic kidney disease (CKD). Data from 8429 adults attending the China Health and Nutrition Survey were used. Chili intake was assessed using a 3 day, 24 h food record in combination with household food inventory between 1991 and 2009. CKD was defined as an estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73 m2, as measured in 2009. Logistic regression was used to assess the association. Of the 8429 participants, 1008 (12.0%) fit the definition of CKD. The prevalence of CKD was 13.1% in non-consumers of chili and 7.4% among those with chili intake above 50 g/day. After adjusting for demographics, lifestyle factors (i.e., smoking, alcohol drinking, physical activity), dietary patterns, and chronic conditions, the odds ratio (OR) (95% CI) for CKD across chili consumption levels of none, 1-20 g/day, 20.1-50 g/day, ≥50.1 g/day were 1.00 (reference), 0.82 (0.67-1.01), 0.83 (0.65-1.05), and 0.51 (0.35-0.75), respectively (p for trend 0.001). There was no interaction between chili intake with gender, income, urbanization, hypertension, obesity, or diabetes. This longitudinal large population-based study suggests that chili consumption is inversely associated with CKD, independent of lifestyle, hypertension, obesity, and overall dietary patterns

Trajectories of Dietary Patterns, Sleep Duration, and Body Mass Index in China: A Population-Based Longitudinal Study from China Nutrition and Health Survey, 1991-2009.

No study has used trajectories of dietary patterns to examine their effects on sleep duration and body mass index over time in the Chinese population. We analyzed data from adults participating in the China Health and Nutrition Survey between 1991 and 2009. Dietary intake was measured by a 24-h recall method over three consecutive days. Height and body weight were measured, and sleep duration was self-reported. Multivariable mixed linear models were applied to examine the association between trajectories of dietary patterns (using a latent class model) and sleep duration as well as BMI. Four trajectories of a traditional pattern (characterized by rice, meat, and vegetables) and three trajectories of a modern pattern (characterized by fast food, milk, and deep-fried food) were identified. Participants with a high and rapid increase trajectory of the modern dietary pattern had the shortest sleep duration (β = -0.26; 95% CI: -0.40, -0.13). Participants with a high and stable intake of the traditional dietary pattern had the lowest BMI (β = -1.14; 95% CI: -1.41, -0.87), while the participants with a high and rapid increase trajectory of the modern dietary pattern had the highest BMI (β = 0.74; 95% CI: 0.34, 1,15). A rapid increase in the modern dietary pattern is associated with shorter sleep duration and higher BMI

Protein intake among patients with diabetes is linked poor glycemic control

Background: Nutrition therapy is considered a key component of diabetes management. High-protein diets are recently gaining more popularity. Knowledge regarding the potential glycemic effect of protein in people with type 2 diabetes has been a particular interest. Methods: This study is a cross-sectional study based on NHANES data collected on participants aged 40 years and older who attended the surveys cohorts of 2011–2012 and 2013–2014. Data on 1058 participants were included in the analysis. Glycemic control was measured as HbA1c level and patients were categorized into quartiles of daily protein intake. Analysis adjusted for age, gender, race and energy intake muscle strength (quartile), sedentary activity, income to poverty ratio, education, smoking, alcohol drinking and BMI. Logistic regression models were produced to investigate the impact of high protein intakes on odds of poor glycemic control (HbA1c ≥ 7). Results : After controlling for muscle strength (quartile), sedentary activity, income to poverty ratio, education, smoking, alcohol drinking and BMI; patients in Quartile 4 for protein intake had 260% increased risk for poor glycemic control as compared to those in quartile 1. These results are limited because the analysis did not consider the source of protein (animal vs plant). Further studies are needed

Riboflavin Intake Inversely Associated with Cardiovascular-Disease Mortality and Interacting with Folate Intake: Findings from the National Health and Nutrition Examination Survey (NHANES) 2005-2016.

The association between intakes of riboflavin and mortality has not been examined intensively in general populations. In this study, 10,480 adults in the 2005-2016 National Health and Nutrition Examination Survey (NHANES) were followed-up until 2019 for their vital status. Riboflavin and folate were assessed by two-day 24 h recall. The date and cause of death were obtained from the US Mortality Registry. The risks of all-cause mortality and cardiovascular disease (CVD) mortality were investigated using a Cox regression analysis. During a mean of 8.5 years follow-up, there were 1214 deaths registered (including 373 deaths from CVD and 302 from cancer). Compared to low level (quartile 1, Q1) of riboflavin intake, the hazard ratios (HRs) (95% confidence interval (CI)) for high level (quartile 4, Q4) were 0.53 (0.31-0.90) for CVD mortality and 0.62 (0.48-0.81) for all-cause mortality. The inverse association between riboflavin intake and CVD mortality was only significant among those with a high intake of folate ( for interaction 0.045). Those with a high folate intake (Q4) and low intake of riboflavin (Q1) had the highest risk of CVD mortality (HR 4.38, 95% CI 1.79-10.72), as compared with a high intake of both riboflavin and folate. In conclusion, riboflavin intake was inversely associated with all-cause mortality and CVD mortality, and the association was modified by folate intake

Ultra-Processed Food Consumption Associated with Incident Hypertension among Chinese Adults—Results from China Health and Nutrition Survey 1997–2015

Objective: Ultra-processed food (UPF) has been shown to increase the cardiometabolic health risks. We aimed to determine the association between UPF intake based on the NOVA classification and the risk of hypertension incidence during 1997–2015. Methods: Data from 15,054 adults aged ≥ 20 years (47.4% males) attending the China Nutrition and Health Survey (CNHS) were used. Food intake at each survey was assessed by a 3-day 24 h dietary recall and weighed food record method between 1997–2011. Cox regression was used to assess the association between UPF intake and incident hypertension. Results: During a mean average of 9.5 years (SD 5.5) of follow up, 4329 hypertension incident cases were identified. The incident rates (per 1000) for non-consumers and 1–49, 50–99, and ≥100 g/day of UPF intake were 29.5 and 29.5, 33.4, and 36.3, respectively. Compared with non-consumers, the hazard ratios (95% CI) for UPF intake of 1–49, 50–99, and >100 g/day were 1.00 (0.90–1.12), 1.17 (1.04–1.33), and 1.20 (1.06–1.35), respectively, (p = 0.001) after adjusting for potential confounding factors. There was a significant interaction between UPF intake and age with a higher risk in the younger group (<40 years) than in the older one. Conclusion: UPF consumption was dose-responsively associated with increased risk of hypertension among Chinese adults, especially in younger groups

Ultra-processed food consumption and obesity among children and adolescents in China-Findings from China Health and Nutrition Survey

Background Children and adolescents are increasingly exposed to processed food in China, however, its association with obesity has not been investigated. Objectives To assess the consumption of ultra-processed food (UPF) and its association with overweight/obesity among children and adolescents in China. Methods A total of 3437 children and adolescents aged 6–18 years, participating at least twice in the China Nutrition and Health Survey, were included. Food intake was collected using a 3-day 24-h dietary recall method at home visits. Body weight, height and waist circumference (WC) were measured during the survey. UPF was defined by food process levels using NOVA classification. Overweight/obesity was defined by the international age- and sex-specific BMI and WC cut-offs. The association between UPF consumption and overweight/obesity was assessed using mixed effect logistic regression analyses adjusted for socio-demographic, economic, behavioural, dietary and health factors. Results The mean daily UPF consumption of the study population (mean age 9.3 years) increased from 9.7 in 1997 to 60.0 grams in 2011. The adjusted odds ratios (OR) (95% CI) for overweight/obesity (using BMI) for UPF consumption of 0, 1–49, 50–99 and ≥ 100 g/day were 1.00, 1.38 (0.98–1.94), 2.01 (1.25–3.24) and 1.53 (0.82–2.86), respectively (p-trend =0.013). Similarly, the corresponding adjusted ORs (95% CI) for central obesity (using WC) were 1.00, 1.84 (1.30–2.60), 2.13 (1.30–3.48) and 2.15 (1.14–4.05) (p-trend<0.001). Conclusions Higher long-term UPF consumption was associated with an increased risk of overweight/obesity among children and adolescents in China.The authors thank the National Institute of Nutrition and Food Safety, China Centre for Disease Control and Prevention, Carolina Population Centre, the University of North Carolina at Chapel Hill, the NIH (R01\u2010HD30880, DK056350 and R01\u2010HD38700) and the Fogarty International Centre for financial support for the CHNS data collection and analysis files from 1989 to 2006 and both parties plus the China\u2010Japan Friendship Hospital, Ministry of Health for support for CHNS 2009 and future surveys.
