Studies have shown that 25-hydroxyvitamin D [25(OH)D] is predictive of survival following a diagnosis of cancer. However, evidence of the relationship between 25(OH)D and the survival of patients with pancreatic cancer has been inconsistent. We hypothesized that circulating 25(OH)D concentrations may be positively correlated with better prognosis in advanced pancreatic cancer. PubMed, EMBASE, Cochrane Library, and Web of Science database entries up to April 2023, along with the reference lists of related studies, were searched. Additionally, we extracted observational studies reporting the association between 25(OH)D concentration and the outcome of interest (overall survival, OS) in advanced pancreatic cancer patients aged 18 years or older. Ultimately, 7 articles involving 2369 patients were included in this systematic review and meta-analysis. The results indicated that 25(OH)D concentrations were positively correlated with OS (HR=2.37, 95% CI: 2.22–2.54, P<0.001). No association was found between 25(OH)D and progression-free survival. There was significant heterogeneity between studies in terms of OS (I2=85.5%, P<0.001). Our subgroup analysis revealed that this high heterogeneity may be attributed to the studies’ different regions, designs, and sample sources and detection methods of 25(OH)D. Additionally, Begg's and Egger's tests indicated the presence of publication bias. To our knowledge, this is the first meta-analysis to evaluate the association between 25(OH)D concentrations and OS among patients with pancreatic cancer. Our results suggested that circulating 25(OH)D concentrations were positively correlated with OS, indicating that 25(OH)D may be a potential prognostic marker in advanced pancreatic cancer.

Caloric restriction has been associated with improved cardiometabolic health. Available data in humans are commonly based on short follow-up periods, specific diets, or population groups. We hypothesized that participants of a population-based cohort (Epidemiological Health Investigation of Teenagers in Porto) with a dietary pattern characterized by a lower energy intake during adolescence have a better cardiometabolic profile in adolescence and young adulthood than other dietary patterns. At aged 13 and 21 year evaluations, diet, anthropometric, and cardiometabolic measures were assessed. Diet was assessed through a food frequency questionnaire and, at 13 years, summarized in dietary patterns identified by cluster analysis. The lower intake dietary pattern included 40% of the participants. The energy intake misreport was estimated using the Goldberg method. Analysis of variance and analysis of covariance were used to compare cardiometabolic risk factors according to dietary patterns. The mean energy intake was 2394 and 2242 Kcal/d for the total sample at aged 13 years (n = 962) and 21 years (n = 862), respectively. Those belonging to the lower intake dietary pattern showed a 25% and 5% lower energy intake, respectively. In the cross-sectional analysis at aged 13, adolescents belonging to the lower intake dietary pattern presented lower glucose, insulin, triglycerides, and blood pressure values after adjusting for body mass index and parents’ education level. Among the plausible reporters, differences were only statistically significant for glucose and systolic blood pressure. Our data support that a dietary pattern characterized by a lower energy intake may contribute to a better cardiometabolic profile in adolescents. However, no significant effect was found in young adulthood.
An incorrect cutoff was used, leading to null results

High-dose vitamin D supplementation can increase total osteocalcin concentrations that may reduce insulin resistance in individuals at risk for prediabetes or diabetes mellitus. Magnesium is a cofactor in vitamin D metabolism and activation. The purpose of this study was to determine the combined effect of vitamin D and magnesium supplementation on total osteocalcin concentrations, glycemic indices, and other bone turnover markers after a 12-week intervention in individuals who were overweight and obese, but otherwise healthy. We hypothesized that combined supplementation would improve serum total osteocalcin concentrations and glycemic indices more than vitamin D supplementation alone or a placebo. A total of 78 women and men completed this intervention in 3 groups: a vitamin D and magnesium group (1000 IU vitamin D3 and 360 mg magnesium glycinate), a vitamin D group (1000 IU vitamin D3), and a placebo group. Despite a significant increase in serum 25-hydroxyvitamin D concentrations in the vitamin D and magnesium group compared with the placebo group (difference = 5.63; CI, –10.0 to –1.21; P = .001) post-intervention, there were no differences in serum concentrations of total osteocalcin, glucose, insulin, and adiponectin or the homeostatic model assessment of insulin resistance (HOMA-IR) among groups (P > .05 for all). Additionally, total osteocalcin (β = –0.310, P = .081), bone-specific alkaline phosphatase (β = 0.004, P = .986), and C-terminal cross-linked telopeptide (β = 0.426, P = .057), were not significant predictors of HOMA-IR after the intervention. Combined supplementation was not associated with short-term improvements in glycemic indices or bone turnover markers in participants who were overweight and obese in our study. This trial was registered at clinicaltrials.gov (NCT03134417).

Malnutrition in under-five children (i.e. children under the age of 5 years) remains a major public health problem. Due to the reductive adaptation in children with severe acute malnutrition (SAM), changes in bone health are often subtle. We hypothesized that children with SAM have higher rates of bone resorption than bone formation, which can be assessed using bone turnover markers. In this cross-sectional comparative study, we evaluated the status of bone turnover markers - serum osteocalcin and serum tartrate-resistant acid phosphatase-5b (TRAP 5b) in under-five children with SAM. Thirty children (6 - 59 months) with SAM (defined as per WHO criteria) were enrolled as cases and another 30 children (age and sex matched) with normal nutritional status (weight for height -1SD to +1SD) were enrolled for comparison of bone turnover markers. Serum TRAP 5b concentrations were significantly higher in children with SAM compared to children with normal nutritional status [mean (SD) 22.6(15.3) vs. 11.3(9.6), (P = 0.009)], while serum osteocalcin concentrations were comparable between the two groups [mean (SD) 40.6(17.9) vs. 36.0(12.5), (P = 0.344)]. Frequency of hypocalcemia and vitamin D deficiency were also significantly high in children with SAM (P < 0.05). An inverse correlation was found between serum calcium and serum osteocalcin (r = -0.383, P< 0.05). Our results indicate that children with severe acute malnutrition (SAM) have a higher bone resorption rate than children with normal nutrition status indicating compromised bone health.

Based on previous studies, we hypothesized that the dietary inflammatory potential in pregnant women might influence maternal and child health. The objective of this work is to review the literature on the association of Dietary Inflammatory Index (DII) during pregnancy with early and late maternal and child health outcomes. We searched Cochrane; Embase; Pubmed; Scopus, Web of Science and in the Virtual Health Library. Observational studies on DII in the gestational period that met the objective of this review were selected. There was a double-blind evaluation of 185 studies, of which 16 were included in narrative synthesis and 9 in meta-analysis. High methodological quality, longitudinal studies (87.5%) and the Food Frequency Questionnaire for DII evaluation (68.8%) prevailed. Outcomes studied were: gestational diabetes mellitus (n = 5), gestational age at delivery (n = 7), type of delivery (n = 3), gestational weight gain or pre-gestational body mass index (n = 11), anthropometry at birth (n = 8) and of the child up to ten years old (n = 4). Higher maternal DII was associated with increased risk of small-for-gestational-age babies (OR: 1.15; 95% CI: 1.08, 1.21; I2: 29%; p = 0.24) and low birth weight (<2.500g) (OR: 1.16; 95% CI: 1.06, 1.26; I2: 56%; p = 0.10). The association between higher maternal DII and higher risk of obesity in late childhood is also suggestive. Thus, maternal diet may be a modifiable factor of inflammation in pregnancy associated with health outcomes of the offspring.

Zinc deficiency has many adverse effects, including growth retardation, loss of appetite, vascular diseases, cognitive and memory impairment, and neurodegenerative diseases. In the current study, we investigated the hypothesis that dietary zinc inadequacy affects neurotrophic factors and proteostasis in the brain. Three weeks old Wistar/Kyoto male rats were fed on either a zinc-deficient diet (D; <1 mg zinc /kg diet; n=18) or pair-fed with the control diet (C; 48 mg Zn /kg diet; n=9) for a period of 4 weeks. Subsequently, the rats in the D group were subdivided into two groups (n=9), in which one group continued to receive a zinc deficient diet while the other received zinc supplemented diet (R; 48 mg Zn/kg diet) for three more weeks after which rats were sacrificed to collect brain tissue. Markers of ER stress, ubiquitin-proteasome system (UPS), autophagy, and apoptosis, along with neurotrophic factors, were investigated by immunoblotting, and the proteasomal activity was analyzed by the spectrofluorometric method. The results showed altered UPS and autophagy components and increased gliosis, ER stress, and apoptosis markers in zinc-deficient rats compared to the control group. Zinc repletion for three weeks could partially restore these alterations, indicating a necessity for an extended duration of zinc supplementation. In conclusion, a decline in zinc levels below a critical threshold may trigger multiple pathways leading to brain-cell apoptosis.
Dietary n-3 and n-6 polyunsaturated fatty acids differentially modulate the adiponectin and leptinmediated major signaling pathways in visceral and subcutaneous white adipose tissue in high fat diet induced obesity in Wistar rats

Obesity is a chronic metabolic disease that involves excessive accumulation of fat in white adipose tissue (WAT). Apart from storing excess fats, WAT also serves as an important endocrine organ secreting adipocytokines such as adiponectin and leptin. Adiponectin and leptin bind to their transmembrane receptors adiponectin receptor 1 (AdipoR1)/adiponectin receptor 2 (AdipoR2) and Ob-R, respectively, and mediate their effect on metabolism by regulating multiple downstream targets. Dietary fat is considered the main culprit behind obesity development. Numerous preclinical studies have highlighted role of essential polyunsaturated fatty acids (PUFAs), particularly n-3 PUFAs, in prevention of obesity. Despite emerging data, there still is no clear understanding of the mechanism of action of n-3 PUFAs and n-6 PUFAs on adipose tissue function in two functionally and anatomically different depots of WAT: visceral and subcutaneous. We designed this study using a high fat diet (HFD) fed rodent model of obesity to test our hypothesis that n-3 and n-6 PUFAs possibly differentially modulate adipokine secretion and downstream metabolic pathways such as peroxisome proliferator-activated receptor-γ (PPAR-γ), protein kinase B (AKT)-forkhead box O1 (FOXO1), and Janus kinase-signal transducer and activator of transcription in obesity. The results of the current study showed that n-3 PUFAs upregulate the expression of AdipoR1/R2 and ameliorate the effects of HFD by modulating adipogenesis via PPAR-γ and by improving glucose tolerance and lipid metabolism via AKT-FOXO1 axis in fish oil fed rats. However, n-6 PUFAs did not show any remarkable change compared with HFD fed animals. Our study highlights that n-3 PUFAs modulate expression of various targets in adiponectin and leptin signaling cascade, bringing about an overall reduction in obesity and improvement in adipose tissue function in HFD induced obesity.

Evidence has suggested that nutrition is a preventive factor against cardiovascular disease (CVD) risk. Because of a sharp growth in published meta-analyses and pooled analyses in recent years, a reassessment of old evidence is needed. We aimed to determine the level of evidence for the association between the consumption of different food groups/items and dietary fiber and the incidence risk of CVDs, hypertension, and atrial fibrillation from meta-analyses and pooled analyses of observational studies. Databases Scopus, PubMed/Medline, and Web of Science were searched for related studies. Fifty-eight articles met the inclusion criteria for evidence grading. In summary, grading the level of evidence showed a suggestive inverse association between the higher consumption of fruits, whole grains, fish, legumes, nuts, and dietary fibers with the incidence risk of hypertension and different types of CVD. Also, there was a probable inverse association between the higher consumption of total and low-fat dairy products and the risk of hypertension. Higher red meat consumption had a probable association with the increased risk of ischemic stroke. Higher consumption of processed meat and poultry also had a suggestive direct association with the incidence risk of stroke and hypertension. We have tried to present a comprehensive and useful overview of the level of evidence based on the most updated findings. The summary of results in the current umbrella review can be a helpful tool for nutritionists, dietitians, and researchers to establish new studies and identify research gaps in related issues.

Evidence supports that growth trajectory during infancy has a major impact on body composition. We aimed to examine body composition in children born small for gestational age (SGA) or appropriate for gestational age (AGA) adjusted for postnatal growth velocity. We enrolled 365 children, 75 SGA and 290 AGA, aged 7 to 10 years, examining anthropometrics, skinfold thickness, and body composition using bioelectrical impedance analysis. Growth velocity was defined as rapid or slow (weight gain > or <0.67 z-scores, respectively). Gestational age, sex, delivery mode, gestational diabetes, hypertension, nutrition, exercise, parental body mass index (BMI), and socioeconomic status were considered. At a mean of 9 years of age, SGA compared with AGA-born children, had significantly lower lean mass. BMI was negatively associated with SGA status (beta = 0.80, P = .046), after adjusting for birth weight, delivery mode, and breastfeeding. The lean mass index was negatively associated with SGA status (beta = 0.39, P = .018), after adjusting for the same factors. SGA-born participants with slow growth velocity had significantly lower lean mass in comparison to AGA-born counterparts. SGA-born children with rapid compared with those with slow growth velocity had significantly higher absolute fat mass. BMI was negatively associated with a slow postnatal growth pattern (beta = 0.59, P = .023), and the lean mass index was negatively associated with a slow postnatal growth pattern (beta = 0.78, P = .006), after adjusting for the same factors. In conclusion, SGA-born children presented a lower lean mass in comparison to AGA-born counterparts, whereas BMI and lean mass index were negatively associated with slow postnatal growth velocity.

As one of the most significant probiotics, Limosilactobacillus reuteri (L. reuteri) has been exploited as a nutritional supplement. We hypothesized that L. reuteri consumption might improve the significant risk factors of cardiovascular disease, including blood pressure, blood lipid, and blood glucose. However, previous clinical studies have shown controversial results. This study aims to explore the effect of L. reuteri consumption on these risk factors. PubMed, Embase, Scopus, the Cochrane Library, and Web of Science were searched for eligible randomized controlled trials published before May 2022. A total of 6 studies with 4 different L. reuteri strains and including 512 participants were included. The results showed that L. reuteri consumption significantly reduced total cholesterol (TC) by −0.26 mmol/L compared with the control group. In contrast, it did not affect systolic blood pressure, diastolic blood pressure, fasting blood glucose, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol (LDL-C), or triglycerides. Subgroup analysis showed a significant reduction in TC when participants were 5 × 109 colony-forming unit or the length of the intervention was <12 weeks. Strain subgroup analysis showed that L. reuteri NCIMB 30242 significantly reduced TC and LDL-C. In conclusion, L. reuteri consumption has a significant TC-lowering effect, which can effectively reduce the risks of cardiovascular disease associated with hypercholesterolemia. However, the results do not support the effectiveness of L. reuteri consumption on other metabolic outcomes. Further examination of larger sample sizes is needed to confirm these findings.

The effects of following the MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diet on metabolic health remains understudied. This cross-sectional analysis of 163 adults investigated associations between adherence to the MIND, Mediterranean, Dietary Approaches to Stop Hypertension (DASH), and Healthy Eating Index (HEI-2015) diets and metabolic syndrome (MetS) features and visceral adiposity. We hypothesized the MIND diet would show the most beneficial associations with MetS risk factors. Diet adherence was assessed using the Dietary History Questionnaire II. Visceral adipose was assessed using Dual-energy X-ray absorptiometry. Waist circumference and systolic and diastolic blood pressure were obtained. Fasting blood triglycerides, high-density lipoprotein cholesterol, and glucose concentrations were determined. Stepwise regression analyses were applied. Waist circumference was inversely associated with DASH (β=-0. 21, P<0.01), HEI-2015 (β=-0.18, P=0.01), and MIND (β=-0.19, P<0.01). Triglycerides were inversely associated with DASH (β=-0.19, P=0.01), HEI-2015 (β=-0.18, P=0.02) and MIND (β=-0.23, P<0.01). High-density lipoprotein cholesterol was positively associated with Mediterranean (β=0.18, P=0.02) and MIND (β=0.21, P<0.01). Systolic blood pressure was inversely associated with Mediterranean (β=-0.18, P=0.02), DASH (β=-0.30, P<0.01), HEI-2015 (β=-0.24, P<0.01), and MIND (β=-0.25, P<0.01). Diastolic blood pressure was inversely associated with Mediterranean (β=-0.26, P<0.01), DASH (β=-0.34, P<0.01), HEI-2015 (β=-0.24, P<0.01), and MIND (β=-0.31, P<0.01). Fasting glucose was inversely associated with MIND (β=-0.19, P=0.02). Visceral adiposity was inversely associated with Mediterranean (β=-0.19, P<0.01), DASH (β=-0.22, P<0.01), HEI-2015 (β=-0.22, P<0.01), and MIND (β=-0.28, P<0.01). While each diet exhibited potential benefits for metabolic outcomes, only greater MIND diet adherence was associated with lower visceral adiposity and each MetS feature in adults.

Because of the maternal diet's importance, numerous studies have examined the effects of olive oil on pregnancy outcomes. This study provides a systematic review that evaluates the evidence between olive oil consumption and maternal-fetal outcomes. We hypothesized that olive oil reduced the risk of adverse pregnancy complications. We searched Web of Science, Scopus, PubMed, and Biblioteca Virtual em Saúde electronic databases (October and November 2021). The keywords used were pregnancy, olive oil, and pregnancy outcomes. This review included all the available studies in English and Portuguese. The exclusion criteria were (1) unrelated to olive oil consumption, (2) other outcomes, and (3) animal studies. The review included 9 articles (6 experimental and 3 observational). In the maternal outcome studies (n = 6), a higher olive oil consumption was associated with a lower prevalence of gestational diabetes mellitus, preeclampsia, and cardiovascular risk. In the fetal outcome studies (n = 8), olive oil consumption was associated with a lower risk for small- or large-for-gestational-age infants. Olive oil consumption confers protective effects on pregnancy outcomes; however, further studies are needed that are specifically designed for the impact of olive oil consumption on maternal-fetal outcomes.

It is hypothesized that plasma proportion of selected fatty acids (FAs) and dietary habits are linked with the risk of cardiovascular disease (CVD) in postmenopausal women. Therefore, this study was designed to determine the association of plasma FA composition and markers of dietary habits with an atherogenic index of plasma (AIP), a predictor of CVD risk in postmenopausal women. In total, 87 postmenopausal women with an average age of 57 ± 7 years were recruited and their dietary intake, anthropometric and biochemical parameters, and FA status in total plasma lipid proportions were determined, showing that 65.5% of the participants had a high risk of CVD according to their AIP value. After adjusting for some confounders (age, body mass index, and physical activity level), the risk of CVD was only positively associated with the frequency of consumption of animal fat spreads (butter and lard) of terrestrial origin. Regarding the FA profile, CVD risk was positively associated with the percentages of vaccenic acid, dihomo-γ-linolenic acid, and monounsaturated fatty acids (MUFA; mainly n-7) in total FA, as well as the MUFA/SFA ratio in total plasma and stearoyl-CoA desaturase-16 activity (16:1/16:0 ratio). In contrast, the risk of CVD was negatively associated with percentages of α-linolenic acid, total polyunsaturated fatty acids (PUFA), and PUFA/MUFA ratio in total plasma lipid, and the estimated activity of Δ5-desaturase (20:4/20:3 n-6 ratio). These results support the current recommendations to decrease the frequency of animal fat spread intake because it is associated with a reduced CVD risk based on AIP in postmenopausal women. In accordance with these plasma percentages of ALA, vaccenic acid, dihomo-γ-linolenic acid, PUFA, PUFA/MUFA ratio, and 16:1/16:0 ratio may be important parameters in CVD risk assessment.

Accumulating evidence has suggested that curcumin may protect against cerebral ischemia-reperfusion injury (CIRI). However, biological mechanisms vary across studies, limiting the clinical applicability of these findings. We performed a meta-analysis on publications evaluating curcumin administration in rat models of CIRI. Furthermore, we sought to test the hypothesis that curcumin alleviates CIRI through diminishing oxidation and inflammation. We searched PubMed, Embase, Web of Science, and Cochrane from the starting date of each database to May 2022 for experimental rat studies exploring the use of curcumin after ischemia reperfusion. Included articles were assessed for bias using SYRCLE's risk of bias tool. Data were aggregated by a random effects model. Curcumin administration significantly reduced neurological deficit score (20 studies; pooled mean difference [MD] = –1.57; 95% CI, –1.78 to –1.36, P < .00001), infarct volume (18 studies; pooled MD = –17.56%; 95% CI, –20.92% to –14.20%; P < 0.00001), and brain water content (8 studies, pooled MD = -11.29%, 95% CI: -16.48%, -6.11%, P < .00001). Compared with control, the levels of superoxide dismutase, glutathione, and glutathione peroxidase were significantly higher, whereas the levels of reactive oxygen species, malondialdehyde, interleukin-1β, interleukin-6, interleukin-8, and nuclear factor kappa B were significantly lower (P < .05). Subgroup analysis raised the possibility that intervention affections differed by curcumin's dose. To our knowledge, this is the first meta-analysis of curcumin's neuroprotection and mechanisms in rat CIRI models. Our analysis suggests the neuroprotective potential of curcumin in CIRI via antioxidant activity and anti-inflammatory effect. More research is required to further confirm the effectiveness and safety of curcumin on ischemic stroke therapy.

Green tea extract (GTE) is a potential mitigator of oxidative stress, and F2-isoprostanes are a reliable biomarker of oxidative stress. Genetic polymorphisms in the catechol-o-methyltransferase (COMT) gene may modify tea catechin metabolism, prolonging exposure. We hypothesized that GTE supplementation would decrease plasma F2-isoprostanes concentrations compared with placebo and that participants with the COMT genotype polymorphisms would experience a more significant expression of this outcome. This study was a secondary analysis of the Minnesota Green Tea Trial, a randomized placebo-controlled, double-blinded trial investigating the effects of GTE in women who were generally healthy and postmenopausal. The treatment group consumed 843 mg of epigallocatechin gallate daily for 12 months versus placebo. Participants in this study had a mean age of 60 years, were predominantly White, and most had a healthy body mass index. GTE supplementation did not significantly change plasma F2-isoprostanes concentrations compared with placebo after 12 months (P for overall treatment = .07). There were no significant interactions between treatment and age, or body mass index, physical activity, smoking history, and alcohol intake. COMT genotype did not modify the effect of GTE supplementation on F2-isoprostanes concentrations in the treatment group (P = .85). Among participants in the Minnesota Green Tea Trial, consuming GTE supplements daily for 1 year did not result in a significant decrease in plasma F2-isoprostanes concentrations. Likewise, the COMT genotype did not modify the effect of GTE supplementation on F2-isoprostanes concentrations.

Dairy and nondairy plant-based alternative proteins are reported to differentially influence body weight; however, most research has compared plant-based alternatives with isolated dairy proteins rather than a complete milk protein (containing casein and whey). This is notable given that people do not generally consume isolated dairy proteins. Therefore, the present study aimed to investigate the impact of a soy protein isolate (SPI) on factors influencing body weight gain in male and female mice in comparison to skim milk powder (SMP). Based on current knowledge in rodents, we hypothesized that SPI would promote body weight gain compared with SMP. Mice (n = 8 per sex per diet) consumed a moderate-fat diet (35% kcal from fat) containing either SPI or SMP for 8 weeks. Body weight and food intake were measured weekly. Energy expenditure, physical activity, and substrate use were measured using metabolic cages. Fecal energy content was measured with bomb calorimetry. Body weight gain and food intake during the 8-week feeding study was not different in mice consuming either SPI or SMP; however, males had a higher body weight, adiposity, and feed efficiency compared with females (all P < .05). Fecal energy content was approximately 7% higher in both male and female mice fed the SPI diet compared with the SMP diet. Neither protein source affected substrate utilization, physical activity, or energy expenditure. Physical activity in the dark phase trended higher in females compared with males (P = .0732). The present study suggests that the consumption of SPI in the context of a moderate-fat diet has little impact on numerous factors influencing body weight regulation in male and female mice compared with a complete milk protein.

The identification of factors associated with 25-hydroxycholecalciferol (25(OH)D) concentration can help suggest more specific interventions for older adults. In this cross-sectional study of older adults from southern Brazil, we hypothesized that some sociodemographic, behavioral, and health factors positively or negatively influence the 25(OH)D concentration in this population. This analysis was performed using data from the second wave of the EpiFloripa Aging Cohort Study (2013-2015). Serum 25(OH)D levels were classified according to the guidelines of the Endocrine Society. Multinomial logistic regression was performed to evaluate the relative risks of sociodemographic, behavioral, and health factors in each 25(OH)D category. A total of 574 older adults (aged 63-93 years) participated in this study. The prevalence of insufficiency (21-29 ng/mL) was 43.7% and that of deficiency (≤20 ng/mL) was 23.5%. In the adjusted analysis, female sex, higher levels of low-density lipoprotein cholesterol (LDL-C ≥160 mg/dL), obesity by adiposity (body fat percentage [%fat], male ≥31%; female ≥43%), and body mass index (BMI, >30 kg/m2) presented higher relative risks for insufficiency than for sufficiency. For those with deficiency, the associated factors were female sex, disability in 4 or more activities of daily living (ADLs), LDL-C ≥100 mg/dL, and obesity by %fat and BMI. A protective factor against insufficiency and deficiency was active leisure-time physical activity (PA, ≥150 min/week). Our results demonstrated that being female and having modifiable factors, such as high levels of LDL-C, obesity, and disability on ADLs, were negatively associated with hypovitaminosis D. On the other hand, leisure-time PA was positively associated with adequate serum vitamin D concentration.

Nutrition Research publishes original research articles, communications, and reviews on basic and applied nutrition. The mission of Nutrition Research is to serve as the journal for global communication of nutrition and life sciences research on diet and health. The field of nutrition sciences includes, but is not limited to, the study of nutrients during growth, reproduction, aging, health, and disease.Original research articles must declare a research hypothesis and include aspects of mechanisms. Reviews are open to systematic reviews and meta-analyses but the review must provide a critical analysis of existing nutrition evidence, identify gaps in knowledge, and include recommendations for future research. Communications are limited in length and preliminary data that addresses a potential mechanism is acceptable. Authors are encouraged to read and follow the Guide for Authors and Author Submission ChecklistArticles covering basic and applied research on all aspects of nutrition sciences are encouraged, including: nutritional biochemistry and metabolism; metabolomics, nutrient gene interactions; nutrient requirements for health; nutrition and disease; digestion and absorption; nutritional anthropology; epidemiology; the influence of socioeconomic and cultural factors on nutrition of the individual and the community; the impact of nutrient intake on disease response and behavior; the consequences of nutritional deficiency on growth and development, endocrine and nervous systems, and immunity; nutrition and gut microbiota; food intolerance and allergy; nutrient drug interactions; nutrition and aging; nutrition and cancer; obesity; diabetes; and intervention programs.Another focus of the Journal is to publish research that advances the understanding of nutrients and health protectants in food for improving the human condition. Of interest are manuscripts on the development of biomarkers for assessing how dietary components influence health status in the human. A further publishing goal of Nutrition Research is to bridge the gap between clinicians working in nutrition and health and biomedical scientists engaged in areas of biochemistry and molecular and cell biology to improve health. Investigators doing research in these areas are urged to submit articles.The Journal also encourages submission of manuscripts describing investigations in animal models and cell cultures that utilize methodologic approaches or techniques in biochemistry, immunology, molecular biology, toxicology, and physiology. Such investigations must include clear research objectives for hypothesis testing and elucidating mechanisms. Nutrient intakes in human populations and novel analytical techniques for bioactive compounds are within the scope of the mission for Nutrition Research.
