The dietary inflammatory index (DII®) and human papillomavirus infection: a cross-sectional study of US women

BackgroundDiet may influence susceptibility of human papillomavirus (HPV) infection by affecting inflammation and immunity. However, the association between HPV infection and the inflammatory potential of diet has not been investigated. The research aimed to examine the correlation between HPV status and the dietary inflammatory index (DII®).MethodsWe utilized data from the National Health and Nutrition Examination Survey (NHANES) 2003–2016 to investigate the correlation between DII and HPV status among 9,256 women aged 18–59 years. DII scores were calculated based on 24-hour dietary recall interviews. The association between HPV status and DII was analyzed using weighted logistic regression and restricted cubic spline (RCS).ResultsWomen with HPV infection exhibited higher DII scores than those without HPV infection. An increased likelihood of HPV infection was found to be significantly associated with higher DII scores (OR = 1.05, 95% CI: 1.01–1.09, P = 0.021), after full multivariate adjustment. Compared with the lowest tertile of DII scores, the ORs (95% CIs) for HPV infection were 1.20 (1.01, 1.42) and 1.27 (1.07, 1.51) for the second and third tertiles, respectively (P for trend = 0.006). RCS analysis showed a U-shaped relationship between DII and HPV infection, with a breakpoint identified at 0.13.ConclusionsOur findings suggest that a pro-inflammatory diet is associated with an increased likelihood of HPV infection among women in the United States. Dietary interventions to reduce inflammation may help prevent HPV infection and related diseases.

The association between dietary carbohydrate intake and the risk of hyperlipidemia among reproductive-aged women in the US: A cross-sectional study.

The association between dietary carbohydrate intake and hyperlipidemia remained incompletely understood. This study aimed to explore the association between dietary carbohydrate intake and the risk of hyperlipidemia among reproductive-aged women in the US. The study utilized data from the National Health and Nutrition Examination Survey (NHANES) conducted from 2005 to 2020. Dietary intake information was assessed via interviews using 24-hour dietary recall interviews, and hyperlipidemia diagnosis adhered to the National Cholesterol Education Program guidelines. Univariate and multivariate logistic regression analyses, along with restricted cubic splines (RCS) and stratified analyses, were conducted to investigate the association between dietary carbohydrate intake and the risk of hyperlipidemia. A total of 6,791 women of reproductive age, with a mean age of 34.87 (±8.57) years, were included in the final analysis. In the multivariate logistic regression model adjusting for covariates, a higher percentage of energy from carbohydrate was positively correlated with the risk of hyperlipidemia (adjusted odds ratio (AOR): 1.014, 95% CI: 1.004-1.024). Analyzing the percentage of energy from carbohydrate as a categorical variable, compared to the lowest quartile, the third quartile (AOR: 1.263, 95% CI: 1.031-1.546) and the highest quartile (AOR: 1.411, 95% CI: 1.083-1.839) were associated with increased hyperlipidemia risk. Additionally, a linear relationship (P for nonlinearity = 0.088) existed between the percentage of energy from carbohydrate and the risk of hyperlipidemia, with an inflection point identified at 49.64. This study found that elevated dietary carbohydrate intake was associated with an increased the risk of hyperlipidemia in reproductive-aged women. These findings implied that reproductive-aged women should pay closer attention to reducing their carbohydrate intake.

Association between vitamin B2 intake and cognitive performance among older adults: a cross-sectional study from NHANES

The impact of vitamin B2 (riboflavin) intake on cognitive performance among older adults in the United States (US) remains inadequately understood. This study aimed to explore the association between vitamin B2 intake and cognitive performance among non-institutionalized elderly people in the US. Weighted logistic regression was used to evaluate the association between vitamin B2 intake and cognitive performance. Vitamin B2 intake was determined from the mean of two 24-hour dietary recall interviews. Three cognitive ability assessment tests, namely the Immediate Recall Test (IRT), Animal Fluency Test (AFT), and Digit Symbol Substitution Test (DSST), were performed. Participants included all older adults over 60 who underwent cognitive scoring, with cut-offs defined based on the lowest quartile (25th percentile) for each test (the cut-offs for the three scores were 15.625, 12, and 33, respectively). Sensitivity analysis, including dose-response curves, subgroup analyses, interaction effects, per 1 standard deviation (SD), recommended dietary allowance (RDA), and residual energy model analysis, were performed to solidify the solid association between vitamin B2 and cognitive performance. A total of 2893 individuals aged over 60 were included, with a mean age of 69 (7) years, and 46% were men. There was a significant association between vitamin B2 intake and all three cognitive scores (IRT, Odds Ratio = 0.77, 95% confidence interval: [0.65,0.92]; AFT, 0.75, [0.64,0.88]; DSST, 0.72, [0.59,0.88]). Moreover, vitamin B2 intake above the RDA reduced the risk of low cognitive performance (IRT, 0.66, [0.46,0.93]; AFT, 0.83, [0.62,1.11]; DSST, 0.65, [0.45,0.92]) compared to intake below the RDA. Dose-response curves indicated that higher vitamin B2 intake was negatively associated with the risk of low cognitive performance. Physical activity may modify the association between vitamin B2 and cognitive performance. Vitamin B2 intake was positively associated with cognitive performance among older adults. Adequate vitamin B2 intake could help protect cognitive function.

Association between dietary magnesium intake and all-cause mortality among patients with diabetic retinopathy: a retrospective cohort study of the NHANES 1999-2018.

This study aimed to investigate the association between dietary magnesium intake and all-cause mortality among diabetic retinopathy (DR) patients. In this retrospective cohort study, data of 1,034 DR patients were extracted from the National Health and Nutrition Examination Survey (NHANES) (1999-2018). Dietary magnesium data were obtained from two 24-hour dietary recall interviews, and categorized into quartiles. Potential confounders were selected using weighted univariate Cox regression models. Weighted univariate and multivariate Cox regression models were used to explore the association between dietary magnesium intake and all-cause mortality in DR patients. The results were presented with hazard ratios (HRs) and 95% confidence intervals (CIs). Associations were further explored for subgroups related to age, gender, cardiovascular disease, and chronic kidney disease. Our study included 1,034 DR patients, of whom 438 (42.36%) died. The mean age of all patients was 63.26 (0.51) years old, with a median follow-up time of 75.00 months. Higher magnesium intake was associated with lower all-cause mortality risk (HR=0.58, 95%CI: 0.38-0.88) in DR patients. The association remained for those aged <65 years (HR=0.35, 95%CI: 0.15-0.81), male patients (HR=0.48, 95%CI: 0.27-0.84), patients without chronic kidney disease (HR=0.43, 95%CI: 0.23-0.82), and patients with a history of cardiovascular disease (HR=0.63, 95%CI: 0.39-1.02). DR patients with adequate magnesium intake exhibited a lower incidence of all-cause mortality. Further studies are needed to validate our findings and explore the optimal strategy for magnesium supplementation in DR patients.

High Dietary Inflammatory Index increases the risk of female infertility: An analysis of NHANES 2013-2018

Diet-related inflammation, which can be evaluated using the dietary inflammatory index (DII), is increasingly related to female infertility. However, studies on the association between DII and infertility are limited. In this study, we aim to explore the association between DII and infertility and its dose-effect relationship among women aged 20 to 45 years through a cross-sectional analysis of the National Health and Nutrition Examination Survey 2013–2018. A total of 2613 women aged 20 to 45 years were included and analyzed. The DII was calculated using the first 24-hour dietary recall interview data and divided into quartiles. Weighted multivariable logistic regression and restricted cubic spline analysis were used to explore the relationship between DII and infertility. The odds ratio (OR) (95% confidence interval [CI]) for the association between DII and infertility was 1.06 (0.96–1.19) after multivariable adjustment. Compared with the first quartile (anti-inflammatory diet), the fourth quartile of DII (pro-inflammatory diet) was more strongly associated with an increased risk of infertility, with an OR of 1.61 (95% CI, 1.05–2.47). Restricted cubic splines showed a J-shaped nonlinear association between DII and infertility (P for nonlinear = .003), with a cutoff point of 2.45. When DII was higher than 2.45, the OR for infertility was 1.95 (95% CI, 1.49–2.54). Similar results were observed among the subgroup analyses. In conclusion, this study found high DII (pro-inflammatory diet) increases the risk of female infertility. DII had a J-shaped nonlinear relationship with female infertility, whose cut point is 2.45. Controlling the intake of pro-inflammatory food may be beneficial for female infertility.

The Relationship Between Fermented Dairy Consumption with Cognitive Function Among Older US Adults: Data from the NHANES 2011-2014.

The aging global population has led to an increased burden of cognitive impairment in older adults. This study examined the relationship between fermented dairy intake and cognitive function in this population. Yogurt, cheese, and fermented dairy consumption were assessed through two 24-hour dietary recall interviews, categorized into low, medium, and high intake groups. Multivariate linear regression was employed to examine the relationship between fermented dairy intake and cognitive tests, including the Alzheimer's Disease Word Learning Immediate Recall Test (CERAD-IRT), CERAD Delayed Recall Test (CERAD-DRT), Animal Fluency Test (AFT), Digit Symbol Substitution Test (DSST), and global cognitive z-scores, adjusting for potential confounding factors. The study comprised 2,462 participants (average age 69.34±6.75 years, 52.07% female). Among yogurt consumers, global cognition and AFT z-scores are notably higher than non-consumers. Conversely, individuals who consume cheese display significantly lower CERAD-DRT z-scores. Compared to participants not intake fermented dairy, consumers of fermented dairy show significantly higher AFT and DSST z-scores and lower CERAD-DRT z-scores. Moreover, when categorizing individuals based on their intake of fermented dairy, those with low and medium consumption show significantly higher AFT and DSST z-scores, as well as significantly lower CERAD-DRT z-scores compared to non-consumers. Our study suggests that moderate consumption of fermented dairy products is associated with better executive function and verbal fluency in the elderly.

Dietary protein sources, genetics, and cardiovascular disease incidence

BackgroundTo explore the potential correlation between the amount and source of dietary protein and cardiovascular disease (CVD), as well as the potential impact of genetic susceptibility on these connections. MethodsWe performed a prospective analysis of 98,224 participants from the UK. We measured dietary protein intake using two 24-hour dietary recall interviews. To analyze the data, we used multivariable-adjusted Cox regression models and restricted cubic spline models. Additionally, we calculated weighted genetic risk scores. ResultsA total of 8818 new cases of CVD were documented, which included 4076 cases of coronary artery disease (CAD) and 1126 cases of stroke. The study found a J-shaped association (p nonlinearity = 0.005) between CVD risk and the percentage of energy obtained from consuming plant protein. Higher intake of plant protein and whole protein was associated with a decreased risk of CVD. On the other hand, larger intakes of animal protein was linked to a higher occurrence of CAD. Additionally, increased intake of plant protein was also linked to a lower incidence of stroke. Replacing 5 % of animal protein-based energy intake with plant protein-based energy intake resulted in a 5 % decrease in CVD risk. LimitationsThere remains an effect of residual confounders. ConclusionThe consumption of larger amounts of plant protein, whole protein, and nut protein was found to be associated with a lower risk of CVD events. Conversely, higher intakes of animal protein was associated with an increased risk of CAD events. Furthermore, replacing 5 % of energy intake from animal protein with energy intake from plant protein was found to reduce the risk of CVD by 5 %.

Socio-cultural norms in the local food system and potential implications for women’s dietary quality in rural northern Ghana

Women’s activities within the local food system are linked to their dietary quality. Their ability to consume a nutritious diet may be influenced by socio-cultural norms; often, the influence of these norms has not been adequately studied. This study examined how socio-cultural norms linked with rural food systems can potentially exert adverse effects on women’s diets. The study was conducted in two rural communities, Yilkpene and Kpachilo, in Northern Ghana, between May and July 2016. Both selected study communities were chosen because they had similar population sizes, dietary patterns, and access to social services. Using a qualitative approach, sixteen key informant interviews with community and institutional leaders, 11 focus group discussions comprising 87 community members, and forty 24-hour dietary recall interviews with women of reproductive age were used to explore the nature of the local food system linked with socio-cultural norms. Transcribed interviews were coded and analyzed, thematically, using pre-determined and emerging themes. A total of 143 women and men participated in the study with women dominating the sample. The components of the food system in both communities were constructed, primarily, around men. Quantities, quality, and varieties of produce, its distribution, and intra-household allocation were dominated by male perceptions and practices that determine access and ownership of productive resources, and pre-determined roles and responsibilities of household members. Men dominated production of economic crops (cereals, and legumes); women produced vegetables, and limited quantities of legumes and cereals, mainly for home consumption. Men controlled allocation of cereals for household meal preparation; more expensive complementary ingredients were provided by women. Although women prepared household meals, men received the ‘lion’s share’ of nutrient-dense components. Forty-five percent of women could not meet minimum dietary diversity of at least five food groups in their diets. The local food system in Northern Ghana is dominated by gender-driven socio-cultural norms, which constitutes a potential barrier to women achieving dietary adequacy. Interventions should deliberately address these culturally-established barriers, especially in contexts where subsistence farming is the main source of livelihood. Key words: Food system, Socio-cultural norms, Barriers, Women, dietary quality

Association between carotenoid intake and periodontitis in diabetic patients.

This study aimed to evaluate the association between dietary carotenoid intake and periodontitis in diabetic patients. Data on diabetic patients were collected from the National Health and Nutrition Examination Survey (NHANES) 2009-2014 for this cross-sectional study. Dietary intake of carotenoids was assessed through the first 24-hour dietary recall interview. Full-mouth periodontal examinations were conducted by trained dental examiners. Subgroup analysis was conducted in terms of age, gender, the number of missing teeth, cardiovascular disease, smoking, and anti-diabetic drugs. Totally 1914 diabetic patients were included, with 1281 (66.93%) in the periodontitis group. After adjusting for age, gender, race, education, smoking, dental implants, hepatitis, and the number of missing teeth, α-carotene intake ≥55.82 mcg was associated with lower odds of periodontitis than α-carotene intake <55.82 mcg [OR = 0.70, 95% CI: 0.53-0.91, P = 0.010]; lutein and zeaxanthin intake ≥795.95 mcg was associated with decreased odds of periodontitis than lutein and zeaxanthin intake <795.95 mcg (OR = 0.75, 95%CI: 0.57-0.98, P = 0.039). The association between carotenoid intake and periodontitis varied across different subpopulations. In diabetes, dietary intake of α-carotene and lutein and zeaxanthin was inversely associated with the odds of periodontitis, which may facilitate clinical periodontitis management.

Association between the composite dietary antioxidant index and constipation: Evidence from NHANES 2005-2010.

Dietary antioxidants have been found to improve various diseases, including digestive, cardiovascular, and urinary disorders. However, the relationship between CDAI and constipation remains unclear. This study aims to investigate the potential link between CDAI and constipation among adults in the United States. This study utilized data from the National Health and Nutrition Examination Survey (NHANES) collected between 2005 and 2010. Dietary data from the respondents were obtained through two 24-hour dietary recall interviews. Multiple statistical methods, including multivariable logistic regression, subgroup analysis, and smooth curve fitting analysis, were used to explore the association between CDAI and chronic constipation. A total of 10,904 participants were included in the study, of whom 1,184 were identified as having chronic constipation. After adjusting for potential confounders, multivariable logistic regression analysis showed that higher CDAI was significantly associated with a lower risk of constipation (OR = 0.958 [0.929, 0.987]). Compared to the lowest quartile, the highest quartile of CDAI was associated with a significantly reduced prevalence of constipation (OR = 0.704 [0.535, 0.927]). Subgroup analysis indicated that differences in gender, alcohol intake, and smoking status might influence the association between CDAI and constipation. Smooth curve analysis revealed an "n" shaped relationship between CDAI and constipation among non-alcohol consumers, with a turning point at a CDAI value of 1.08. An elevated CDAI is negatively correlated with the incidence of chronic constipation, suggesting that increasing dietary antioxidant intake may reduce constipation prevalence. These findings underscore the importance of dietary antioxidants in maintaining gut health and provide comprehensive guidance for clinical and public health practices.

Association between the Composite Dietary Antioxidant Index and Stroke: A cross-sectional Study.

The composite dietary antioxidant index (CDAI) is indeed a valuable nutritional tool used to evaluate the overall antioxidant capacity of an individual's daily food consumption. The CDAI was calculated from the intake of six antioxidant components in the diet, including vitamin A, vitamin C and vitamin E, carotenoids, selenium, and zinc. This study aimed to determine the association between CDAI and stroke. Utilizing data from the 2003-2018 NHANES dataset, CDAI was computed by summarizing the intake of six dietary antioxidants based on 24-hour dietary recall interviews. The relationship between CDAI and stroke was examined using multivariate logistic regression and restricted cubic spline analysis. This study ultimately included 39,432 participants, of whom 1,527 (3.87%) had a stroke. The multivariate logistic regression model 3 that fully adjusted all confounding variables showed a negative association between CDAI and stroke (OR = 0.97; 95% CI:0.95, 0.99). The highest tertile of CDAI saw a 23% drop in the prevalence of stroke compared to the lowest tertile (OR = 0.77; 95%CI: 0.64,0.92). Restricted cubic spline suggested that this negative correlation was nonlinear with an inflection point of -2.99. Subgroup analyses and interaction tests showed that this negative correlation was more applicable in patients with prediabetes (P < 0.05). There was a non-linear negative correlation between CDAI level and stroke prevalence, and this correlation was more significant in people with pre-diabetes. Appropriate CDAI levels may contribute to the management of stroke risk.

Association between dietary omega-3 intake and coronary heart disease among American adults: The NHANES, 1999-2018.

Omega-3 has been extensively studied for its cardiovascular disease (CVD) benefits. However, the results of this evidence are inconsistent. Therefore, in this study, dietary omega-3 intake was investigated further in relation to coronary heart disease (CHD) risk among U.S. adults. We used data from the National Health and Nutrition Examination Survey (NHANES) database for people ages 20 years and older between 1999 and 2018 to conduct a cross-sectional survey. The Medical Condition Questionnaire (MCQ) was used to determine CHD status. We measured dietary omega-3 intake using two 24-hour dietary recall interviews. Multivariate logistic regression and subgroup analysis were used to explore the correlation between dietary omega-3 intake and CHD. The dose-response relationship between the two was analyzed with a restricted cubic spline (RCS). 31,184 study subjects were included, of whom 1,604 (5.14%) were patients with CHD. By quintile (Q) of dietary omega-3 intake, after adjusting for all confounding factors, compared with Q1, when total dietary omega-3, alpha-linolenic acid (ALA), docosapentaenoic acid (DPA), eicosatetraenoic acid (ETA), eicosapentaenoic acid (EPA), and docosahexenoic acid (DHA) intake reached Q5, the odds ratio (95% confidence interval, CI) of CHD were 0.76 (0.60, 0.96), 0.73 (0.57, 0.94), 0.70 (0.54, 0.92), 0.66 (0.50, 0.85), 0.84 (0.69, 1.02), and 0.83 (0.64, 1.07), respectively, while EPA and DHA were not significantly associated with the disease (Trend p > 0.05). Intake of omega-3 and CHD were linearly related (P for nonlinear = 0.603). No significant interactions were found within subgroups except for the age group (P for interaction = 0.001). Sensitivity analysis and multivariate logistic regression results are generally in agreement. Total dietary omega-3, ALA, DPA, and ETA intake were negatively associated with CHD risk. In contrast, EPA and DHA had no significant correlation with CHD.

Associations of dietary inflammatory index with low estimated glomerular filtration rate, albuminuria and chronic kidney disease in U.S adults: Results from the NHANES 2011–2018

Background and AimsChronic Kidney Disease (CKD) is characterized by a high inflammation status with ever-increasing prevalence, and defined as low estimated glomerular filtration rate (eGFR) or albuminuria. Both low eGFR and albuminuria can have independent effects on the body. The dietary inflammatory index (DII) is a validated tool used to assess the inflammatory potential of the diet. We aim to explore not only the association between DII and CKD, but also the associations of DII with low eGFR and albuminuria, respectively. In addition, their associations in different subgroups remain to be explored. Methods and Results18,070 participants from the 2011-2018 NHANES with complete data of dietary intake and laboratory data were involved in our study. The data of 24-hour dietary recall interview was used to calculate DII, CKD could be reflected by laboratory data of creatinine and albumin. Then weighted multivariate logistic regression models and subgroup analyses were performed. The prevalence of low eGFR, albuminuria and CKD were 6.8%, 9.8% and 14.5%, respectively. A positive association between DII and low eGFR was observed (OR=1.12, 95%CI: 1.05-1.21), Q2, Q3 and Q4 are positively associated with a significant 39%, 65% and 71% increased risk of low eGFR compared with Q1 (P for trend<0.05). DII was also associated with CKD (OR=1.06, 95%CI: 1.01-1.11). ConclusionSignificant positive associations of DII with CKD and low eGFR were observed. But we didn’t find such association between DII and albuminuria.

Dietary Behaviors and Social Determinants of Health Among Adults Living with Sickle Cell Disease

Background: Social determinants of health (SDoH) may impact outcomes in sickle cell disease (SCD), and recent literature reports that particular SDoH, such as food insecurity and housing insecurity, may impact diet choices for individuals with SCD. Notably, health outcomes in SCD are linked to diet choices through increased protein and caloric needs, and through nutrients, such as polyphenols, omega fatty acids and micronutrients, which are involved in SCD pathophysiology. The connection between SDoH and diet quality may occur through multiple pathways including access to food, affordability, chronic pain and psychosocial factors at the individual and family level. Importantly, the impact of this connection may relate to outcomes such as pain frequency, hospitalizations, and SCD pathophysiologic biomarkers, such as inflammation. Study Design and Methods: The Diet and SCD Study (NCT: 05170412) is an observational mixed-methods study initiated in 2021 at the National Institutes of Health Clinical Center (NIH CC) in Bethesda MD with a target sample of 75 adults living with SCD in the United States. The purpose of the study is to evaluate associations between SDoH (food insecurity, neighborhood food access, education, employment, healthcare access), dietary intake, and population health related outcomes among adults living with SCD. Study inclusion criteria consists of adults (≥18 years of age) residing within the United States at the time of screening who have a confirmed diagnosis of sickle cell disease with any genotype, and are not hospitalized at the time of enrollment. To ensure participation from adults in diverse regions of the United States, the study has a hybrid design of in-person and telehealth procedures. In-person protocol visits are conducted at the NIH CC. The CC clinical visit includes a clinical assessment, anthropometric measurements, phlebotomy, as well as monitored/proctored electronic surveys that collect SDoH and disease severity variables. The telehealth protocol visit includes a virtual clinical assessment, phlebotomy at a local laboratory center, as well as the same monitored/proctored electronic surveys completed by CC clinical visit participants. A dietary behavior semi-structured interview is conducted at both the CC clinical visit and telehealth protocol visit to garner participants' personal stories related to food choices and diet. Laboratory variables include SCD disease specific markers, amino acid levels, and measurement of inflammatory cytokine markers. All participants undergo two unannounced phone-administered 24-hour dietary recall interviews with trained NIH nutrition staff to measure recent dietary intake. Data from 24-hour recall interviews are used to determine fluid, caloric, macro and micronutrient, and polyphenol intake. Usual dietary intake of foods of potentially related to SCD pathophysiology (cruciferous vegetables and thiocyanate-rich foods) is measured through self-administered electronic 12-month food frequency questionnaires. Primary objectives are to evaluate social determinants of health related to food security and access relevant to disease severity among adults living with sickle cell disease in the U.S. Secondary outcomes are to evaluate the association of dietary quality, specific dietary nutrient intake and serum levels, including amino acids and polyphenols, with disease severity. Tertiary outcomes include evaluating inflammatory and glucometabolic biomarkers with measures of social determinants of health. When completed, the Diet and SCD study will provide important information on the associations between SDoH, dietary quality, inflammatory biomarkers and disease severity for adults living with SCD and provide initial data for future cohort and intervention studies.

Association Between Dietary Fiber Intake and Cardiometabolic Risk Factors in Adolescents in the United States

To determine the association between dietary fiber intake and markers of cardiometabolic risk in adolescents, with blood pressure (BP) as the primary outcome of interest and secondary outcome measures including other established markers of childhood cardiometabolic risk, such as obesity, lipids, albuminuria, estimated glomerular filtration rate (eGFR), and uric acid. Dietary fiber intake was assessed by two 24-hour dietary recall interviews, which were averaged and corrected for body weight. Logistic and linear regression models were used to analyze the cross-sectional association between dietary fiber and cardiometabolic markers. Participants aged 13-17 years in the National Health and Nutritional Examination Survey 2009-2018 who completed a 24-hour dietary recall survey were included. Exclusion criteria included pregnancy, small for gestational age status, and history of major health comorbidities. In fully adjusted regression models, low dietary fiber intake was significantly associated with greater diastolic blood pressure (β=-13.29; 95% CI, -20.66 to -5.93), body mass index z-score (β=-0.91; 95% CI, -1.47 to -0.34), and uric acid (β=-0.80; 95% CI, -1.44 to -0.16). The association found between low dietary fiber intake and poor childhood cardiometabolic risk markers indicate a need for prospective studies using fiber intake as a dietary intervention in childhood and as a tool for prevention of many chronic conditions.

Association of dietary inflammatory potential and non-alcoholic fatty liver disease in US adults.

Long-term inflammatory effects of diet may elevate the risk of non-alcoholic fatty liver disease (NAFLD). The present study aims to investigate dietary patterns associated with inflammation and whether such diets were associated with the risk of NAFLD. Data were collected from the 2017-2018 National Health and Nutrition Examination Survey. Dietary intake was obtained through two 24-hour dietary recall interviews, and levels of inflammatory biomarkers were assessed in blood samples. NAFLD was defined as a controlled attenuation parameter (CAP) ≥ 274 dB/m. Reduced-rank regression (RRR) analysis was used to derive sex-specific inflammatory dietary patterns (IDPs). Logistic regression analysis was used to examine the association between IDPs and NAFLD. A total of 3570 participants were included in this study. We identified the IDP characterized by higher intake of added sugars, and lower intake of fruits, vegetables, whole grains, seafood high in n -3 fatty acids, soybean products, nuts, seeds, yogurt, and oils. After multivariate adjustment, the highest tertile of the IDP scores had a significantly higher risk of NAFLD than the lowest tertile [odds ratio (OR) = 1.884, 95% confidence interval (CI) = 1.003-3.539, P for trend = 0.044 for males; OR = 1.597, 95% CI = 1.129-2.257, P for trend = 0.010 for females]. Overall, the IDP was positively associated with the prevalence of NAFLD. The findings may provide dietary prevention strategies for controlling chronic inflammation and further preventing NAFLD.

Association between dietary inflammatory index and urinary flow rate: a nationwide study, NHANES 2009–2016

Some evidence have suggested that various nutrients and inflammatory factors might influence the lower urinary tract function. However, the correlation between diet and urinary flow rate (UFR) is not clear. Our study aimed to evaluate the association between the dietary inflammatory index (DII) and UFR. We performed a cross-sectional analysis using data from the National Health and Nutrition Examination Survey (NHANES) database from 2009–2016. The dependent and independent variables were UFR and DII score, respectively. Dietary information was collected by 24-hour dietary recall interviews method, and DII scores were computed based on it. Tertiles group was divided according to DII scores. The study included 17,114 participants for whom data on DII and UFR were available, with a mean age of 35.68 ± 20.96 years. Participants with higher DII score presented lower UFR levels (β= −0.05; 95% CI: [−0.06–0.04]). In addition, the risk of UFR decline elevated significantly gradual across DII score tertiles (p for trend <0.001). Our findings revealed that increased intake of pro-inflammatory diet, as a higher DII score, is correlated with decreased UFR. These results might be useful for the public health system to provide primary prevention recommendations for lower urinary tract voiding problem, but further high-quality prospective research is needed.

Association of shift work and dietary inflammatory potential with all-cause death among us hypertensive population: national health and nutrition examination study, 2005–2010

Background & aimsThe individual effect of working schedule on survival in the hypertensive population has not been adequately studied. Shiftworkers are also prone to unhealthy lifestyles like pro-inflammatory diet. Therefore, we assessed the effect of shift work and its joint association with dietary inflammatory potential on mortality risk among the large US nationally representative sample of adult hypertensive population.MethodsData were from a nationally representative prospective cohort among US hypertensive population (n = 3680; weighted population, 54,192,988). The participants were linked to the 2019 public-access linked mortality archives. The working schedule were self-reported using the Occupation Questionnaire Section. Dietary inflammatory index (DII) scores were equally calculated using the 24-hour dietary recall (24 h) interviews. Multivariable Cox proportional hazards regression models were used to estimate hazard ratio and 95% confidence intervals (95%CI) for survival of hypertension individuals by work schedule and dietary inflammatory potential. The joint effect of work schedule and dietary inflammatory potential was then examined.ResultsAmong the 3680 hypertension individuals (39.89% female [n = 1479] and 71.42% white [n = 1707]; weighted mean [SE] age, 47.35 [0.32] years), 592 individuals reported shift work status. 474 (10.76%) reported shift work status with pro-inflammatory dietary pattern (DII scores > 0). 118 (3.06%) reported shift work status with anti-inflammatory dietary pattern (DII scores < 0). 646 (19.64%) reported a non-shift working schedule with anti-inflammatory dietary pattern, while 2442 (66.54%) reported non-shift working schedule with pro-inflammatory dietary pattern. After a median follow-up of 11.67 years (140 months), 317 deaths (cardiovascular diseases (CVD), 65; cancer, 104) were registered. Cox regression analysis showed that shift work was associated with higher risk of all-cause mortality (hazard ratio [HR], 1.48; 95% CI, 1.07–2.06) compared with non-shift workers. In the joint analysis, shift work status combined with pro-inflammatory dietary pattern was associated with the highest all-cause mortality risk. Moreover, adopting the anti-inflammatory diet significantly attenuates the deleterious effect of shift work on mortality risk.ConclusionsIn this large representative sample of adults with hypertension in the U.S., the combination of shift work status with pro-inflammatory dietary pattern was highly prevalent and was associated with the highest risks of death from all causes.

Jordan's Population-Based Food Consumption Survey: Protocol for Design and Development.

One of the factors influencing health and well-being is dietary patterns. Data on food consumption are necessary for evaluating and developing community nutrition policies. Few studies on Jordanians' food consumption and dietary habits at various ages have been conducted, despite the increased prevalence of overweight, obesity, and chronic diseases. This will be the first study focusing on Jordanians' food consumption patterns that includes children, adolescents, adults, and older adults. This cross-sectional study aims to describe the design and methodology of the Jordan's Population-based Food Consumption Survey, 2021-2022, which was developed to collect data on food consumption, including energy, nutrients, and food group intake, from a representative sample of Jordanians and to determine the prevalence of overweight and obesity and their relationship to food consumption. Participants were selected by stratified random sampling, using the Estimated Population of the Kingdom by Governorate, Locality, Sex, and Households, 2020 as the sampling frame. The food consumption survey sample was at the population level, representing gender and age classes (8-85 years old). The data collection period was 6 months. Food consumption was assessed using 24-hour dietary recall (2 nonconsecutive days, 1 week apart) interviews representing weekdays and weekends. In addition to data on food consumption, information on the use of food supplements, sociodemographic and socioeconomic status, and health was gathered. Weight, height, and waist circumference were all measured. The survey included 632 households with 2145 participants, of which 243 (11.3%) were children, 374 (17.4%) were adolescents, 1428 (66.6%) were adults, and 99 (4.6%) were older adults. Three food consumption databases were used to stratify the mean 24-hour dietary recall food consumption into energy intake, carbohydrates, proteins, fats, fiber, vitamins and minerals, and food groups. BMI was calculated and classified as normal, overweight, or obese. Central obesity was classified as normal or abnormal based on the waist-to-height ratio. The survey results will be disseminated based on age, energy, nutrient, and food group consumption. The prevalence of overweight and obesity by age group will be presented, as well as a comparison to the situation in Eastern Mediterranean countries. The survey data will be helpful in nutritional studies, assessing changes in dietary patterns, and developing and evaluating nutrition or health policies. It will be a solid base for developing a future national surveillance system on food consumption patterns with comprehensive food consumption, physical activity, biochemical, and blood pressure data.
