24-h Dietary Recall Research Articles

Associations between eicosapentaenoic acid and docosahexaenoic acid consumption and inflammatory bowel disease in adults: The National Health and Nutrition Examination Survey (NHANES) 2009-2010.

Current evidence on the associations of dietary eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) consumption with the risk of inflammatory bowel disease (IBD) is inconsistent. This study aimed to investigate the relationship between dietary EPA and DHA consumption with the incidence of IBD in a population of the United States, which potentially provides insights for global nutritional prevention and control strategies for IBD. Data were sourced from the National Health and Nutrition Examination Survey for the years 2009-2010. EPA and DHA consumption was measured using twice 24-h dietary recall questionnaires. In the arthritis questionnaire, the incidence of IBD was inquired via a sub-analysis for arthropathy. To assess the relationship between dietary EPA and DHA consumption with the incidence of IBD, binary logistic regression and limited cubic spline models were used. A total of 4,242 individuals aged 20 years and older participated in this survey. IBD was diagnosed in 52 individuals, representing a prevalence of 1.23%. The 95% confidence interval for crude odds ratios (ORs) of IBD in quartiles 2 and 3 of dietary EPA consumption was 0.14 (0.04-0.55) (p<0.05) and 0.36 (0.18-0.73) (p<0.05) when compared to quartile 1, respectively. The 95% confidence interval for crude ORs of IBD in quartile 4 of dietary DHA consumption was 0.09(0.02-0.35) (p<0.05) when compared to quartile 1. For the National Health and Nutrition Examination Survey in 2009-2010, increased dietary EPA and DHA consumption may be related to a decreased risk of IBD in Americans aged 20 and above.

Abstract 4136294: Carbohydrate intakes and cardiovascular disease risk factors in South Asians: Results from 56,024 participants in Bangladesh, India, Pakistan, and Sri Lanka

Background: Evidence on effects of carbohydrate intake with cardiovascular disease risk factors is inconsistent and has limited generalizability to diverse populations such as South Asians, whose carbohydrate intakes are typically high. Aims: We examined the association of the quantity and types of carbohydrate intake with two risk factors for major cardiovascular events– hypertension (HT) and hypercholesterolemia (HC). Methods: We analyzed cross-sectional data from participants aged ≥18 years in the South Asia Biobank in Bangladesh, India, Pakistan, and Sri Lanka. Using dietary data assessed with interviewer-led 24h diet recalls, we calculated intakes of total and subtypes of carbohydrates and several indices of carbohydrate quality. Primary outcomes were HT and HC, defined by medication use, doctor diagnosis, blood pressure and blood lipid levels. With mixed effects Poisson regression, HT and HC was regressed on quantiles of carbohydrate intakes by country to estimate prevalence ratios (PR) and 95% confidence intervals (CI), followed by meta-analysis pooling country-specific estimates. We examined interactions by diabetes status and adiposity. Results: Of 56,024 adults, 36.6% had HT, 16.1% had HC. In pooled multivariable analyses comparing extreme quantiles, total carbohydrate intake was not associated with HT or HC prevalence. Fructose, free sugar and free sugar-to-fiber ratio were associated with higher prevalence of HT (PRs Q5vsQ1 : 1.03-1.15). Higher intakes of cereal fiber (PR Q4vsQ1 : 0.96, 95% CI: 0.95-0.98) and legume fiber (PR Q4vsQ1 : 0.98, 95% CI: 0.97-0.98) were associated with lower prevalence of HT and higher cereal fiber intake with lower HC prevalence (PR Q5vsQ1 : 0.80, 95% CI: 0.75-0.85). Diabetes and adiposity were observed as effect-modifiers (p&lt;0.001). There were null associations in adults with diabetes but in non-diabetic adults, free sugar intake was related positively with HT (PR Q5vsQ1 : 1.07, 95% CI: 1.05-1.09) while fiber intake was inversely related (PR Q5vsQ1 : 0.98, 0.95-0.97). Starch, sugar and free sugar intake were associated positively with HT prevalence in adults with high body fat (≥20% for men; ≥30% for women) and visceral fat (≥10%) levels (PRs Q5vsQ1 : 1.03-1.20); associations were null for low body and visceral fat levels. Associations varied by country (between-country heterogeneity I 2 &gt;60%). Conclusion: Associations of dietary carbohydrates with HT and HC depended on the quality and type of intake in South Asians.

Long-term effect of eating duration on all-cause mortality under different energy intake and physical activity levels.

The long-term impact of eating duration on the risk of all-cause mortality remains unclear, with limited exploration of how different levels of energy intake and physical activity might influence this impact. To investigate, 24484 American adults from the National Health and Nutrition Examination Survey spanning 1999-2018 were included. Eating duration was assessed via 24-h dietary recall, and all-cause mortality data were sourced from the National Death Index. The relationship between eating duration and all-cause mortality was analysed using Cox proportional hazards regression models, restricted cubic splines and stratification analysis with complex weighted designs. The median (IQR) of eating duration for participants was 12·5 (11·0, 14·0) h. In this study, 2896 death events were observed, and the median follow-up time (IQR) was 125 (77, 177) months. After multivariable adjustment, compared with Q1, Q2, Q3 and Q4 had reduced risks of all-cause mortality by 17, 15 and 13 %, respectively. Furthermore, each additional hour of eating duration was correlated with a 2 % decrease in the risk of all-cause mortality. Additionally, a non-linear dose-response relationship was observed between eating duration and the risk of all-cause mortality, showing a U-shaped relationship from 8·9 h to 15·3 h (P for non-linearity < 0·05). Interestingly, the non-linear dose-response relationship was observed exclusively among individuals with high energy intake or a lightly active physical activity level. These findings suggest potential health benefits from adjusting eating duration, though further prospective studies are needed for validation.

Nutrition among nursing home residents: results from the NutriCare study

BackgroundOlder adults living in nursing homes (NHs) are considered a vulnerable population in terms of nutrition. The aim of the present study was to explore the usual intake of energy, macronutrients, and specific food groups, along with offers in the NH menus on a nationally representative sample of Slovenian NH residents and compare dietary patterns with the established recommendations.MethodsThe study was conducted as part of a cross-sectional NutriCare study on 317 residents (65–101 years) from 20 Slovenian NHs in 9 health regions. Relatively independent residents were selected using quota sampling by sex and age. Data collection involved interviews and anthropometric measurements. Usual dietary intake was assessed by a multiple-source method from two 24-h dietary recalls and food frequency questionnaires. Adherence of dietary intake to the recommendations and dietary composition of NH menus were assessed. The Mini Nutritional Assessment (MNA) was used to explore nutritional status.ResultsNotable variability in energy and macronutrient intakes was observed with some participants showing intakes below and others above the recommended values. A high prevalence of BMI &amp;gt; 30 kg/m2 was observed in 39% of participants, indicating potential discrepancies between total energy intake and expenditure. The usual intake of fat was 36% of total energy intake (TEI). The intake of foods of animal origin exceeded dietary guidelines. Intake of carbohydrates (46% TEI in men and 47% TEI in women) as well as dietary fibre (20 g/day for both sexes) was below recommendations. A scarce intake of fruits, vegetables, and cereals was observed. In total, 40% of men and 35% of women had usual daily protein intakes lower than 1 g/kg of body weight. The protein content of breakfast and dinner could be improved. NH residents consumed little food from outside NH. The usual nutrient and food group intakes of residents reflected the NH menu offers.ConclusionThe study results on the usual intake of energy, macronutrients, specific food groups, and offers in the NH menus indicate the potential for optimisation. According to the World Health Organisation, the prevalence of BMI &amp;gt; 30 kg/m2 is notable and warrants attention. Careful meal planning and regular monitoring of the nutritional status of NH residents should be considered.

Relationship between timing of coffee and tea consumption with mortality (total, cardiovascular disease and diabetes) in people with diabetes: the U.S. National Health and Nutrition Examination Survey, 2003–2014

BackgroundPrevious observational studies have suggested diabetic patients should synchronize their foods and nutrient intake with their biological rhythm; however, the optimal intake time of coffee and tea for reducing all-cause and disease-specific mortality in diabetes is still unknown. This study aims to examine by investigating the association of timing for coffee and tea consumption with long-term survival in people with diabetes.MethodsA total of 5378 people with diabetes who enrolled in the National Health and Nutrition Examination Survey from 2003 to 2014 were recruited for this study. Coffee and tea intakes were measured by a 24-h dietary recall, which were divided by different time intervals across the day, including dawn to forenoon, forenoon to noon, noon to evening, and evening to dawn. Weighted cox proportional hazards regression models were developed to evaluate the survival-relationship of coffee and tea consumption with mortality of all-cause, cardiovascular disease (CVD), stroke, and diabetes.ResultsDuring 47,361 person-year follow up, total 1639 death cases were documented, including 731 CVD deaths, 467 heart disease deaths, 99 stroke deaths, and 462 diabetes deaths. After adjustment for potential confounders, compared with participants without drinking coffee during dawn to forenoon, drinking coffee at this period was associated with increased mortality risk of all-cause (HR 1.25, 95% CI 1.05–1.50), CVD (HR 1.41, 95% CI 1.07–1.86), heart-disease (HR 1.47, 95% CI 1.05–2.07), and diabetes (HR 1.50, 95% CI 1.10–2.04). In contrast, drinking coffee during forenoon to noon had lower mortality risk of all-cause (HR 0.80, 95% CI 0.69–0.92), CVD (HR 0.79, 95% CI 0.63–0.99), and heart disease (HR 0.70, 95% CI 0.52–0.94). Similarly, drinking tea during forenoon to noon had lower risk of CVD mortality (HR = 0.62, 95% CI 0.44–0.87).ConclusionsThis study suggests that drinking coffee in dawn to forenoon is linked to a higher risk of death, but having coffee and tea from forenoon to noon is linked to a lower risk of overall mortality, CVD, and heart disease in individuals with diabetes.Graphical

Association between dietary intake of iron and heart failure among American adults: data from NHANES 2009-2018.

Patients with heart failure (HF) often experience iron deficiency. Intravenous iron supplementation has been widely used in clinical practice to facilitate the treatment of HF. However, the association between dietary iron intake and HF still needs to be elucidated. This study aimed to evaluate the impact of dietary iron intake on HF in American adults. The data were extracted from the National Health and Nutrition Examination Survey (NHANES) 2009-2018. Iron dietary intake data were obtained from two 24-h dietary recall interviews. We examined baseline data and HF prevalence in different quartile groups of dietary iron intake (Q1-Q4). Two logistic regression models were established to evaluate the impact of Q4 (highest iron consumption) on the risk of HF. The study included 20,853 American adults (age ≥ 20 years). The participants with the highest iron intake (Q4) had the lowest prevalence of HF (Q1: 3.25%, Q2: 2.18%, Q3: 1.92%, Q4: 1.72%; P < 0.001). After adjusting for possible confounding factors, the highest iron intake (Q4) was significantly associated with a reduced risk of HF compared with that of Q1 (odds ratio 0.58, 95% confidence interval 0.41-0.82; P = 0.003). This association remained stable in subgroups of women, current smokers, and Hispanics other than Mexican Americans. This study revealed that the dietary intake of iron was negatively associated with HF in adults without exceeding the tolerable maximum daily intake of 45mg/day.

Habitual Dietary Patterns of Maintenance Haemodialysis Patients and the Relationship Between Malnutrition Risk-A Multicentre Cross-Sectional Diet Survey.

To identify habitual dietary patterns in maintenance haemodialysis patients and analyse their association with malnutrition. A multicentre cross-sectional dietary survey was conducted among 232 maintenance haemodialysis patients from three centres. A 3-day 24-h diet recall and demographic, clinical and therapeutic information were collected. Factor analysis was used to identify the major dietary patterns among haemodialysis patients. Logistic regression analysis was used to assess the relationship between dietary patterns and malnutrition risk. Three dietary patterns were identified in this study and differed in age, gender and diabetes. An 'animal foods and refined grains' dietary pattern meets guideline requirements. A 'fresh fruits and nuts' dietary pattern had insufficient daily energy and protein intake with the lowest carbohydrates, lipids and minerals intake among haemodialysis patients. A 'dairy products' dietary pattern characterised by low calorie and moderate protein was found to be associated with malnutrition. Habitual dietary patterns of maintenance haemodialysis patients were associated with personal characteristics, specifically age, gender and diabetes. Patients with habitual 'dairy products' dietary patterns may have poor nutritional status. Educating haemodialysis patients about their daily diet pattern, rather than focusing on nutrients, is crucial and will help them to understand it better. Clinical staff can recognise patients at risk of malnutrition by a dietary pattern of lower intake of certain foods. They can recommend a balanced nutritional pattern that increases calories in the total diet and meets protein requirements.

Exploring the correlation between dietary zinc intake and stroke risk in adults based on NHANES database

ABSTRACT Objective To explore the relationship between dietary zinc intake and stroke. Methods Subjects from the National Health and Nutrition Examination Survey (NHANES) database (2015 to 2020) were included. Zinc intake was determined using two 24-h dietary recall interviews, and stroke was determined using the Medical Condition Questionnaire (MCQ). Logistic analysis was used to analyze the association between zinc intake and stroke risk. 1:1 nearest neighbor propensity score matching (PSM) was used to reduce selection bias. Results 4705 subjects were included in the study. Multivariate logistic regression analysis before and after matching showed that increased zinc intake was associated with a reduced risk of stroke. And as zinc intake increases, the risk of stroke shows a gradually decreasing trend. Compared with the Q1 group, the risk of stroke in the Q2, Q3, and Q4 groups was reduced by approximately 0.27 times, 0.29 times, and 0.31 times respectively. And there is no interaction between dietary zinc intake and gender in stroke patients. Conclusion Dietary zinc intake may be a protective factor against stroke, and increasing its intake may prevent or reduce the symptoms of stroke and related diseases.

Association between dietary vitamin B6 intake and constipation: a population-based study

BackgroundNumerous studies have suggested a link between dietary micronutrient intake and the onset of constipation. Nevertheless, there has not been much research done on the potential relationship between vitamin B6 and constipation. The purpose of this study was to determine whether dietary vitamin B6 consumption and chronic constipation are related among adult participants in the National Health and Nutrition Examination Survey (NHANES).MethodThe study made use of information from the 2009–2010 NHANES health and nutrition survey. Respondents’ dietary information was gathered using 24-h dietary recalls. A range of statistical techniques, including as interaction tests, subgroup analyses, and curve fitting analyses, were used to examine the connection between dietary vitamin B6 intake and chronic constipation.ResultThis study included 3,643 patients, with 270 (7.41%) diagnosed with persistent constipation. A fully adjusted multiple logistic regression analysis found that increasing dietary vitamin B6 consumption (OR = 0.78, 95% CI: 0.68–0.89) was linked to a lower incidence of constipation, with significance at p &amp;lt; 0.05. After accounting for numerous factors, the odds ratio and 95% confidence interval for the third tertile compared to the reference group (first tertile) were 0.85 (0.74, 0.98), with statistical significance at p &amp;lt; 0.05. Furthermore, subgroup analysis and interaction assessments revealed a substantial negative link between vitamin B6 intake and the occurrence of constipation, particularly in males and alcohol drinkers (all p-values were less than 0.05).ConclusionThis study found an inverse connection between vitamin B6 consumption and the prevalence of persistent constipation. More extensive prospective trials are needed to fully examine the long-term influence of vitamin B6 on persistent constipation.

Impact of protein consumption on sleep problems: Insights from NHANES data

Sleep problems are common and significantly impact health and well-being. Diet, particularly protein intake, may affect sleep, yet the precise relationship remains unclear. This study investigates the association between protein consumption and sleep problems while considering potential confounders and gender differences, using data from the National Health and Nutrition Examination Survey. Our cross-sectional analysis included 18,077 women (51.3%) and 17,175 men (48.7%), averaging 45.9 years (standard deviation = 17.7). Protein consumption was assessed through 24-h dietary recall interviews and sleep problems were assessed through the question: &amp;ldquo;Have you ever told a doctor or other health professional that you have trouble sleeping?&amp;rdquo; Using binary logistic regression models, we found that 24.6% of individuals reported sleep problems. A statistically significant association emerged between protein consumption and the likelihood of experiencing sleep problems across quartiles of protein intake. Specifically, individuals in the highest quartile of protein consumption had the lowest odds of sleep problems compared to those in the lowest quartile, even after adjusting for various demographic and lifestyle factors (P &lt; 0.001). Gender-stratified analysis revealed a persistent association between protein intake and sleep problems, with a stronger effect observed in females (P &lt; 0.002) compared to males (P = 0.337). Overall, our findings suggest that higher protein consumption is independently associated with reduced odds of sleep problems. This underscores the importance of adequate protein intake for promoting better sleep outcomes and highlights potential implications for public health interventions and clinical practice.

Associations of sugary beverage intake with type 2 diabetes and the role of physical activity: a prospective cohort study

BackgroundHigher consumption of sugary beverages (SB) has been associated with type 2 diabetes (T2D), but whether these associations are modified by physical activity remains unclear. This study aimed to examine the associations of SB intake, including sugar-sweetened beverages (SSB), artificially sweetened beverages (ASB), and natural juices (NJ) with the risk of incident T2D, and the potential role of physical activity.MethodsWe included 153,862 diabetes-free participants in the UK Biobank who completed both the International Physical Activity Questionnaire at recruitment (2006–2010) and at least one 24-h dietary recall questionnaire in 2009–2012. We assessed the associations of each SB with the risk of incident T2D using Cox proportional hazard models, and explored the interactions between each SB and physical activity.ResultsDuring a median follow-up of 11.8 years, 6631 participants developed incident T2D. Participants consuming more SSB and ASB (comparing > 2 to 0 unit/d) had a higher hazard of T2D (hazard ratio [HR]: 1.17, 95% confidence interval [CI]: 1.05–1.31 for SSB; 1.54, 1.37–1.74 for ASB), while medium intake of NJ showed an inverse association (HR> 0–1 vs. 0 unit/d: 0.87, 95% CI: 0.82–0.92; HR> 1–2 vs. 0 unit/d: 0.88, 95% CI: 0.81–0.97) with incident T2D. No significant interactions between physical activity and SSB/ASB were found (P-interaction=0.204 for SSB, 0.926 for ASB), but the protective association of medium NJ intake with T2D was stronger among participants with higher level of physical activity (P-interaction = 0.043).ConclusionsHigher intake of SSB and ASB was related to higher risks of T2D. Medium NJ intake was associated with a lower risk of T2D, particularly among individuals with higher physical activity level. These findings emphasized the importance of healthy beverage intake and adequate physical activity in diabetes prevention.

Effect of school feeding program on dietary folate intake among school adolescent girls in Sidama region, southern Ethiopia

BackgroundEthiopia recently initiated a school feeding program (SFP) that provides nutritious meals to vulnerable students during school to combat malnutrition and improve their nutrition. However, there is limited evidence regarding the program’s impact on dietary folate intake among adolescent girls. Improving folate status in adolescent girls is important to prevent neural tube defect and anemia This study was aimed at assessing the effect of the SFP on dietary folate intake among school adolescent girls in the Sidama Region, Southern Ethiopia.MethodsThis school-based cross-sectional study compared dietary folate intake among adolescent girls enrolled in schools with (n = 290) and without (n = 290) SFP. Multistage sampling method was used to select adolescent girls from 12 schools. The multiple pass 24-h dietary recall method was used to estimate the dietary intake of adolescent girls. Dietary diversity in the preceding day of the survey was assessed with the standard nine-food group score. Nutrient inadequacy was defined as a proportion of adolescents with dietary value of nutrient intake less than the recommended daily allowance (RDA). The dietary folate intake was compared between two groups using multilevel mixed effects linear regression model adjusted for potential confounders.ResultsThe result showed significantly higher mean (±SD) dietary folate intake in SFP beneficiaries (421.12 ± 78.60 μg/day) than the non-beneficiaries (393.26 ± 74.57 μg/day; β = 27.19, p &amp;lt; 0.001). SFP beneficiary girls had a significantly higher mean (±SD) dietary diversity score (5.24 ± 1.35) compared to non-beneficiary girls (4.83 ± 1.54; β = 0.40, p = 0.001). The prevalence of inadequate folate intake was significantly higher among no-beneficiaries (47.4%) compared to beneficiaries (36.9%; p = 0.01).ConclusionThe SFP in Sidama region improved folate intake and dietary diversity of adolescent girls. The evidence from this study supports the expansion of the program to enhance dietary intake of nutrients of adolescent girls in the region.

Total choline intake, liver fibrosis and the progression of metabolic dysfunction-associated steatotic liver disease: Results from 2017 to 2020 NHANES

ObjectivesThis study investigated the cross-sectional relationships of total choline intake with the prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) and its progression to liver fibrosis. Study designThe study used data on total choline intake, hepatic steatosis, and liver fibrosis from the cross-sectional 2017–2020 National Health and Nutrition Examination Survey data, including 24-h dietary recalls and liver ultrasound elastography (FibroScan®). Main outcome measuresSteatosis was defined as a controlled attenuation parameter score ≥ 285dB/m. Fibrosis was defined as median liver stiffness ≥8 kPa. Complex survey-adjusted regression models were used in all analyses. Effect modification by sex, race, and cardiometabolic risk factors was investigated. ResultTotal choline intake was not associated with MASLD status (n = 5687; odds ratio per 100 mg/d [95 % confidence interval]: 0.96 [0.85,1.09]; P = 0.55). However, among people with MASLD, a higher total choline intake was associated with higher odds of fibrosis (n = 2019; 1.15 [1.01,1.30]; P = 0.03). This association was observed in men (P-interaction = 0.1; 1.23 [1.02,1.48]; P = 0.03), but not in women (1.05 [0.88,1.24]; P = 1.0). Choline intake also tended to be positively associated with fibrosis in people with MASLD who were overweight or had central obesity (P-interaction = 0.02; 1.15 [1.00,1.34]; P = 0.06). ConclusionsOverall, no significant association was observed between total choline intake and the prevalence of MASLD. However, in people with MASLD, a higher choline intake was associated with higher odds of developing liver fibrosis. This association appeared to differ by sex and cardiometabolic risk factors.

Food Insecurity Is Common in Patients with Inflammatory Bowel Disease and Is Associated with Increased Ultra-Processed Food Intake.

Food insecurity (FI) is defined as the lack of consistent access to enough food for an active and healthy life. FI affects over 30 million Americans and is associated with poor clinical outcomes and impaired quality of life and drives significant health inequities. Despite the rising prevalence of FI and the federal focus on improving access to healthy food, there is a paucity of research on FI in patients with inflammatory bowel disease (IBD). Therefore, the goal of this study was to define FI in a cohort of IBD patients and determine whether FI was associated with changes in dietary patterns, including specifically an increase in ultra-processed food (UPF) consumption in this high-risk patient population. This was a single-center, retrospective cohort study of patients with a diagnosis of IBD who were 18 years of age or older and who were seen in a nutrition focused clinic. Patients were screened for FI using the Hunger Vital Sign™, a 2-question validated FI screening tool and underwent a 24-h dietary recall. The degree of food processing was assessed using the NOVA Food Classification System. Among 128 patients with IBD, we observed that FI is increasingly prevalent, with 45% of patients reporting difficulty with sufficient grocery access at least "sometimes" in the last 12 months and 10% reporting decreased food access "often" in the prior year. In addition, the patients at high-risk for FI were significantly more likely to eat NOVA 4 UPFs (54% vs. 27%, p = 0.001) and were significantly less likely to eat NOVA 1 unprocessed foods (32% vs. 61%, p = 0.001) as compared to those not at risk for FI. Finally, only a small percentage of those at highest risk for FI were enrolled in a federal food assistance program for grocery support. The prevalence of FI is increasing in patients with IBD and is associated with reduced dietary quality.

Association between dietary vitamin D intake and low muscle mass in US adults: results from NHANES 2011-2018.

To investigate the association between dietary vitamin D intake and low muscle mass (LMM) in a representative adult population, accounting for total energy intake and other potential confounders. This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) involving 8,443 participants. Dietary vitamin D intake was assessed using 24-h dietary recalls, and LMM was defined based on appendicular lean mass (ALM) adjusted for body mass index (BMI). Multivariable logistic regression models were used to examine the association between quartiles of dietary vitamin D intake and the odds of LMM, adjusting for age, gender, race/ethnicity, BMI, total energy intake, and additional covariates. In Model 1, after adjusting for age, gender, race/ethnicity, BMI, and poverty-to-income ratio, participants in the highest quartile of vitamin D intake had an odds ratio (OR) of 0.54 (95% CI: 0.37-0.79) compared to the lowest quartile, with a p for trend <0.001. In Model 2, after further adjustment for total energy intake and several covariates, the association was attenuated but remained borderline significant (p for trend = 0.051). In Model 3, after adjusting for additional health-related factors, the OR for the highest quartile was 0.70 (95% CI: 0.47-1.05), with a significant p for trend of 0.029. This study suggests that higher dietary vitamin D intake may be associated with a reduced risk of LMM. Further longitudinal research is needed to confirm these findings and explore potential interactions between vitamin D and other dietary factors in muscle mass preservation.

Association between dietary calcium intake and constipation in a metabolic syndrome population: evidence from NHANES 2005-2010.

The global prevalence of Metabolic Syndrome (MetS) is increasing, primarily characterized by abdominal obesity, which significantly heightens the risk of cardiovascular diseases, gastrointestinal disorders, and cancers. Constipation is a common gastrointestinal issue that impacts both physiological and psychological health and worsens with age. Calcium, an essential mineral vital for human health, has been proven to be crucial not only for bone health but also beneficial for gastrointestinal health. However, the results regarding its impact on constipation are inconsistent. This study aimed to investigate the relationship between dietary calcium intake and constipation in individuals with MetS. This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2010. Participants were assessed for MetS based on the International Diabetes Federation (IDF) criteria. Dietary calcium intake was evaluated through 24-h dietary recalls, and constipation was defined based on the frequency of bowel movements recorded in the bowel health questionnaire. The relationship between calcium intake and constipation was explored using logistic regression models with adjustment for covariates, and restricted cubic spline analyses were also used to investigate nonlinear relationships. The study included 4,838 adult participants with MetS. Adjusted logistic regression revealed that an increase in dietary calcium intake was significantly associated with a reduced risk of constipation (OR: 0.562, 95% CI: 0.379 to 0.835, p = 0.006). Compared to the lowest quartile, the highest quartile of dietary calcium intake significantly decreased the risk of constipation (OR: 0.282, 95% CI: 0.115 to 0.691, p = 0.008). Results from the restrictive cubic spline analysis indicated a negative linear association between dietary calcium intake and constipation risk (non-linearity p = 0.704). The findings suggested that increased dietary calcium intake is associated with a decreased risk of constipation among MetS patients, emphasizing dietary calcium as a potentially modifiable factor for managing gastrointestinal symptoms in this population.

Associations between dietary nutrient intake and sleep disorders in cancer survivors base on NHANES 2005 to 2018.

Sleep disorders significantly impact the quality of life for many individuals, which remain largely unrecognized. It is widely believed that dietary nutrient intake plays a crucial role in promoting healthy sleep patterns. However, there is lack of research focusing on cancer survivors. This study utilized the National Health and Nutrition Examination Survey (NHANES) database to investigate the correlation between dietary nutrient intake and sleep disorders in cancer survivors. Analyzing data from 2882 cancer survivors in NHANES spanning from 2005 to 2018. Dietary nutrient intake was evaluated through two 24-h dietary recalls. Weighted multivariable logistic regression model was employed to further applied to explore the association between dietary fiber intake and sleep disorders while controlling for relevant confounding factors. Additionally, the nonlinear and dose-response relationships were explored using restricted cubic spline (RCS) regression along with smooth curve fitting and threshold effect analysis. Stratified analysis and interaction analysis were conducted to assess the consistency of the results. Univariable and multivariable analysis demonstrated that dietary fiber intake showed negative correlation with sleep disorders (P < 0.05). Treating dietary fiber intake as continuous variable. After accounting for all covariates, the study reaffirmed the protective role of dietary fiber (odds ratio [OR]: 0.99, 95% confidence interval [CI]: 0.98-0.99, P = 0.044). Analysis of dietary fiber intake in quartiles further supported this trend (P < 0.001). Interestingly, further investigations indicated that dietary fiber intake was not associated with sleep apnea, insomnia, restless legs syndrome, or other types of sleep disorders (P > 0.05). Notably, no statistically significant interactions were observed in all subgroup analyses except poverty income ratio (PIR) (P for interaction < 0.05), indicating that the protective effect of dietary fiber on sleep disorders was more pronounced in individuals with PIR ≥2.5. Our results suggest that adequate dietary fiber intake may be beneficial dietary strategy to reduce sleep disorders in cancer survivors.

Mediterranean diet lowers risk of new-onset diabetes: a nationwide cohort study in China

BackgroundThe Mediterranean diet (MD) has shown promising results in preventing type 2 diabetes, particularly in Mediterranean and European populations. However, the applicability of these benefits to non-Mediterranean populations is unclear, with contradictory findings in the literature.MethodsIn this study, we included 12,575 participants without diabetes at baseline from the China Health and Nutrition Survey (CHNS). Dietary intake was measured by three consecutive 24-h dietary recalls. The Mediterranean diet adherence (MDA) was measured by a score scale that included nine components of vegetables, legumes, fruits, nuts, cereals, fish, red meat, dairy products, and alcohol. New-onset diabetes was defined as self-reported physician-diagnosed diabetes during the follow-up.ResultsDuring a median follow-up of 9.0 years, 445 (3.5%) subjects developed diabetes. Overall, there was an inverse association between the MDA score and new-onset diabetes (per score increment, HR 0.83, 95% CI 0.76–0.90). Moreover, age, sex, BMI, and energy intake significantly modified the association between the MDA score and the risk of new-onset diabetes (all P interactions < 0.05). Greater fruit, fish, and nut intake was significantly associated with a lower risk of new-onset diabetes.ConclusionThere was an inverse association between Mediterranean diet adherence and new-onset diabetes in the Chinese population.

Association between dietary antioxidant levels and diabetes: a cross-sectional study.

The onset and progression of diabetes mellitus (DM) is strongly linked to oxidative stress. Previous studies have highlighted the protective effects of individual dietary antioxidants against diabetes. However, the relationship between a comprehensive combination of dietary antioxidants and diabetes has rarely been examined. Therefore, this study assessed the association between various dietary antioxidant intake levels and diabetes among US adults and further investigated potential associations using the Composite Dietary Antioxidant Index (CDAI). The study employed data from the National Health and Nutrition Examination Survey (NHANES) conducted between 2011 and 2018 for cross-sectional analysis. Dietary information was obtained from two 24-h dietary recall interviews. The CDAI was calculated using intakes of six dietary antioxidants from the dietary information. Multifactorial logistic regression models were employed to investigate the association of different dietary antioxidants and CDAI with DM. The relationship between CDAI and DM was further explored using subgroup analyses and restricted cubic spline curves. A total of 7,982 subjects (mean age 47.32 ± 16.77 years; 48.50% male and 51.50% female) were included in this study. In the multivariate-adjusted single antioxidant model, vitamin C intake was significantly and negatively associated with diabetes prevalence (P for trend = 0.047), while zinc intake demonstrated a potential trend toward reduced diabetes risk (P for trend = 0.088). This association was similarly observed in the multivariate-adjusted model for the Composite Dietary Antioxidant Index (CDAI) in the female population (p = 0.046). Intake of vitamin C was negatively associated with DM prevalence. Additionally, CDAI was found to reduce the risk of DM in the female population.

The association between dietary flavonoid intake and frailty risk among middle-aged and elderly US adults: A nationally representative study

Given the global ageing population, exploring potential dietary prevention strategies to reduce the public health burden of frailty is critically important. Dietary flavonoids offer multiple health benefits; however, there is a scarcity of research evidence regarding their association with the risk of frailty in middle-aged and older adults. This study aimed to assess the association between dietary flavonoid intake and frailty risk among middle-aged and older U.S. adults and to analyse the potential roles of different flavonoid subclasses. This study involved 9063 participants aged ≥40 years. Frailty was evaluated using a frailty index, and flavonoid intake was estimated through two 24-h dietary recalls. Analyses were carried out via multivariable logistic regression, restricted cubic spline models, weighted quantile sum regression, and quantile g-computation models. Additionally, subgroup analyses and interaction tests were conducted for age and gender. The results indicated that higher intakes of total flavonoids and subclasses (anthocyanidins, flavan-3-ols, flavanones, flavones, flavonols) were significantly associated with a lower prevalence of frailty, but isoflavone intake was not associated with frailty. A nonlinear, L-shaped dose-response relationship was observed between total flavonoids and frailty risk. Flavonols and flavanones were identified as the main contributors to the overall effect. Age influenced the association between dietary flavonoids and frailty, with middle-aged adults benefiting more than older adults. This study provides new evidence supporting an inverse association between dietary flavonoid intake and frailty risk, especially for foods rich in flavonols and flavanones.
