Plant and animal protein intake and its association with depression, anxiety, and stress among Iranian women.

BACKGROUND: Mental disorders are conditions that affect the usual function of the brain, causing a huge burden on societies. The causes are often unclear, but previous research has pointed out, as is the case with many other diseases, that nutrition could have a major role in it. Amino acids, the building blocks of proteins, are the main precursor of neurotransmitters (the chemical messengers in the brain) malfunction of which is heavily associated with a wide range of brain disorders. METHODS: We assumed different sources of dietary protein could have different impacts on mental well-being. Hence, we decided to collect the nutritional data (with a validated and reliable semi-quantitative food-frequency questionnaire) from a sample of 489 Iranian women and investigate the association between animal and plant protein sources and the risk of depression, anxiety, and stress. Symptoms of these mental disorders were assessed using a validated Depression, Anxiety, and Stress Scales (DASS) questionnaire with 21 items. RESULTS: After multivariable adjustment, it was shown that women in the highest tertile of animal protein intake were more likely to show symptoms of depression (OR: 2.63; 95% CI: 1.45, 4.71; P = 0.001), anxiety (OR: 1.83; 95% CI: 1.04, 3.22; P = 0.03), and stress (OR: 3.66; 95% CI: 2.06, 6.50; p < 0.001). While no significant association was seen between plant protein and any of the studied mental disorders. CONCLUSION: Overall, our findings suggest that a diet high in animal protein could predispose individuals to mental illnesses.

Association of household socioeconomic status, neighborhood support system and adherence to dietary recommendation among persons with T2DM, a facility-based cross-sectional study in Ghana.

BACKGROUND: Dietary recommendation help persons with diabetes adopt to healthy eating habits to achieve optimal glycemic control. Socioeconomic-status and neighborhood support system can influence adherence to dietary recommendation. The purpose of our study is to assess the association of household-socioeconomic status and neighborhood-support system with adherence to dietary recommendation among persons with type 2 diabetes mellitus (T2DM). METHODS: Facility-based cross-sectional-survey was conducted in Brong Ahafo region, Ghana. Six hospitals were randomly selected and 530 individuals with T2DM consecutively recruited from the selected hospitals for the study. Structured-questionnaires were used to collect socio-demographic variables. Adherence to dietary-recommendation was the outcome-variable, and was assessed using perceived dietary-adherence questionnaire. RESULTS: Age (years) (P-value = 0.005), Physical-Activity level (P-value = 0.024) Receive-moderate Social-Support (P-value = 0.004) and High-Socioeconomic status (P-value = 0.046) were significantly correlated with adherence to dietary-recommendation. Age (years) regression coefficient (ß) -0.089, 95%CI (- 0.12, - 0.001), Being married ß0.103, 95%CI (0.002, 0.02), moderate and low-social support system ß 0.309, 95%CI (0.17, 0.38) and ß-0.192, 95%CI (- 0.26, - 0.06) respectively, and high-socioeconomic status ß 0.197, 95%CI (0.06, 0.25) were significantly associated with adherence to dietary-recommendation. CONCLUSION: Social-support system and socioeconomic-status could be associated with adherence to dietary-recommendation. Therefore, health workers should consider patients' social support system and socioeconomic status as modifiable factors for optimum adherence.

Association of Adherence to Diabetics Feeding Recommendation with Glycaemic Control and with Malnutrition Risk Among Normal Weight Persons with Type 2 Diabetes in Ghana.

BACKGROUND: Diabetes mellitus (DM) is public health problem. Feeding-recommendations help persons with diabetes control glycaemia. The aim was to access the association between adherence to diabetics' feeding recommendation with glycaemic control and with malnutrition risk. METHODS: Cross-sectional study was conducted among 530 baseline normal weight (body mass index [BMI] 18.5 kg/m2-24.9 kg/m2) persons with type 2 diabetes (T2DM) in Brong Ahafo region of Ghana, from August 2018 to September 2019. Adherence to feeding recommendation was evaluated with perceived dietary adherence questionnaire (PDAQ). Malnutrition-risk was assessed using malnutrition universal screening tool. Multinomial logistics regression models were used to assess the association between adherence to diabetics' feeding recommendation with glycaemic control and with malnutrition risk. RESULTS: Participants were generally healthy. Weight (P = 0.011), total cholesterol (P = 0.003) and glycated haemoglobin (HbA1c)% (P < 0.001) were significant with adherence to diabetics feeding recommendation. Low adherence to diabetics' feeding recommendation (adjusted odds ratio [AOR] 2.56; 95% CI: 1.44, 4.56; P < 0.001), low adherence to fruit and vegetables (AOR 2.71; 95% CI: 1.48, 4.99; P < 0.001), low adherence to whole grain, beans, starchy-fruits and plantain (AOR 3.29; 95% CI: 1.81, 6.02; P < 0.001), and low adherence to foods prepared with walnut, canola, sunflower, cotton seed and fish oils (AOR 2.62; 95% CI: 1.49, 4.58; P < 0.001) were significant with poor glycaemic control. Furthermore, low adherence to food prepared with walnut, canola, sunflower, cotton seed, fish or soy oils (AOR 0.54; 95% CI: 0.31, 0.95; P = 0.034) and low adherence to fish and lean meat (AOR 2.09; 95% CI: 1.14, 3.86; P = 0.017) were significant with moderate malnutrition risk. CONCLUSION: This study demonstrates that poor adherence feeding recommendation could be related to glycaemic control and malnutrition risk.

Dietary approaches to stop hypertension (DASH) score and obesity phenotypes in children and adolescents.

BACKGROUND: The prevalence of obesity and its two important phenotypes, the metabolically healthy obese (MHO) and the metabolically unhealthy obese (MUO) are 10.9, 9.1, and 1.8%, respectively, among children and adolescents in Iran. Data on the link between diet quality indices and obesity phenotypes in children and adolescents is scarce. The present study aimed to assess the association of the Dietary Approaches to Stop Hypertension (DASH) score with MHO and MUO, as well as with cardiometabolic risk factors (RFs) in children and adolescents with excess weight. METHODS: This cross-sectional study was conducted on 341 children and adolescents with excess weight aged 6-13 years, selected from primary schools of Tehran. The DASH score was determined based on eight components using a valid and reliable food frequency questionnaire. Anthropometric measures, insulin, fasting plasma glucose, lipid profile, and physical activity levels were collected. MUO was classified based on two definitions: having 2 or more cardiometabolic RFs, or being insulin resistant determined by a homeostatic model assessment of insulin resistance (HOMA-IR) ≥ 3.16. Multivariable logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for MUO phenotypes and cardiometabolic RFs in each tertile of the DASH score after adjustment for confounders. RESULTS: The mean ± SD for age and DASH score was 9.3 ± 1.7 years and 24.0 ± 4.9, respectively. The prevalence of MUO was 62.2% based on RFs, and 43.4% based on HOMA-IR. Participants in the highest tertile of the DASH score had significantly decreased odds for MUO based on HOMA-IR (OR = 0.49; 95% CI: 0.28-0.87) compared with those in the lowest tertile, after adjustment for confounders. However, there were no associations between the DASH score and any of cardiometabolic RFs, or MUO based on RFs (OR = 0.68; 95% CI: 0.38-1.20). CONCLUSION: The DASH score was inversely associated with MUO based on HOMA-IR, but not associated with MUO based on cardiometabolic RFs in this sample of children and adolescents. A DASH-style diet may have favourable effects on insulin sensitivity among children and adolescents with excess weight. Universal definitions for MHO/MUO are required, and longitudinal studies recommended to shed light upon this subject.

Vitamin D downregulates key genes of diabetes complications in cardiomyocyte.

OBJECTIVE: Vitamin D deficiency has been reported to be associated with the incidence of type 1 and type 2 diabetes and worsening of diabetes complications. This study was designed to investigate the effect of vitamin D treatment on the expression of five key genes involved in the development of diabetic cardiomyopathy. METHODS: Twenty-four male Sprague-Dawley rats were randomly divided into three groups. The first group served as control and the other two groups received an intraperitoneal injection of 45 mg/kg streptozotocin (STZ) to develop diabetes. Then groups were treated for 4 weeks either with placebo or vitamin D (two injections of 20,000 IU/kg). Serum levels of glucose, insulin, HbA1c, and advanced glycation end products (AGEs), as well as the gene expression of AGE cellular receptor (RAGE), glyoxalase, aldose reductase, O-GlcNAc transferase (OGT), and glutamine-fructose-6-phosphate aminotransferase (GFAT) and nuclear factor-kB (NF-kB) activity of nuclear extracts were assessed at the end of experiment. RESULTS: Increment in serum cholecalciferol could improve hyperglycaemia and hypoinsulinemia in diabetic rats. In addition, a significant reduction was observed in RAGE, OGT, and GFAT gene expression and NF-kB activity in cardiac myocytes. CONCLUSIONS: Vitamin D might contribute in reducing diabetic cardiomyopathy not only by improving blood glucose and insulin levels but also via downregulating AGE and hexosamine pathways and decreasing NF-kB activity in heart tissue.

Dietary Inflammatory Index in Relation to Carotid Intima Media Thickness among Overweight or Obese Children and Adolescents.

BACKGROUND: Low-grade systematic inflammation triggers atrial wall thickening, which predisposes to several cardiovascular events. Since diet is a strong moderator of systematic inflammation, the literature review-based dietary inflammatory index (DII®) score has been recently introduced for evaluating inflammatory properties of an individual's diet. The aim of the present study was to assess the association of DII, with carotid intima media thickness (cIMT) among overweight or obese children and adolescents. METHODS: A total of 339 children and adolescents (48% girls) aged from 6 to 13 years, with WHO body mass index z-score >1 were enrolled in this cross-sectional study. A valid and reliable semi-quantitative food frequency questionnaire was used to collect dietary intakes and calculate DII score. cIMT was measured in the common carotid artery with high-resolution ultrasonography. RESULTS: In this cross-sectional study, the mean ± SD age of participants was 9.3 ± 1.7 years. Among participants, 68% were obese and 83% were in the pubertal stage. DII ranged from -5.43 to 4.42, with the mean of -2.83 in the lowest, and 1.25 in the highest tertile of DII. When fit as a continuous variable, DII score had no significant association with cIMT after adjusting for potential confounders. However, the participants in the highest DII score tertile compared to the lowest had 2.46-fold increased risk of high cIMT in the multivariable adjusted model (p for trend = 0.02). DISCUSSION/CONCLUSION: Higher DII scores were associated with increased risk of high cIMT.

Development and validation of a knowledge, attitude, and practice questionnaire on nutrition-related cancer prevention for Iranian women.

BACKGROUND: Designing cancer prevention programs needs information on knowledge, attitude, and practice of the community. Unfortunately, this information is not available in Iran. MATERIALS AND METHODS: We developed a questionnaire (NUTCANKAPQ) to assess the knowledge, attitude, and practice of Iranian women regarding cancer prevention dietary habits. We recruited women who had referred to public health-care centers in Tehran, Iran. To assess validity, we applied face, content, and construct validity methods. We performed test-retest approaches to assess reliability, and internal consistency of the questionnaire was assessed through Cronbach's alpha and intraclass correlation coefficients (ICCs). RESULTS: Qualitative content validity was carried out by an expert panel, and internal consistency was deemed satisfactory (Cronbach's alpha, >0.6). We also observed high reliability in the questionnaire (ICC = 0.85). The mean (± standard deviation) scores for knowledge, attitude, and practice of study participants were 28.3 (±14.1), 67.1 (±18.9), and 53.7 (±8.3), respectively. The result of exploratory factor analysis, Kaiser-Meyer-Olkin (KMO), implied that the model was reasonably fit (KMO > 0.6). The final questionnaire included seventy items. CONCLUSION: NUTCANKAPQ is a valid and reliable tool for the assessment of cancer-related nutrition knowledge, attitude, and practice among the Iranian population. Application of NUTCANKAPQ may provide important clues for policy-making and improvement of cancer prevention programs among the Iranian population.

Weight Changes and Metabolic Outcomes in Calorie-Restricted Obese Mice Fed High-Fat Diets Containing Corn or Flaxseed Oil: Physiological Role of Sugar Replacement with Polyphenol-Rich Grape.

OBJECTIVE: Because diet components are important during dieting in obesity treatment, we examined possible beneficial effects of substituting corn oil and sugar with flaxseed oil and grape in calorie-restricted high-fat diets on weight changes as well as improvement in some metabolic markers and related gene expression. METHODS: Seventy-five C57BL/6J male mice were given free access to a high-fat (36% of energy from fat) diet containing corn oil plus sugar (CO + S). After 11 weeks, 15 mice were sacrificed and another 60 were divided among 4 high-fat diet groups with 30% calorie restriction (CR) for the next 12 weeks. The diets contained corn oil (CO) or flaxseed oil (FO) with sugar (S) or grape (G). RESULTS: Despite CR, a weight loss trend was observed only during the first 4 weeks in all groups. CR did not significantly increase SIRT1 gene expression. Higher liver weight was observed in mice consuming FO (p < 0.05). Proliferator-activated receptor gamma (PPARγ) expression decreased in FO + G-CR significantly and even with a reduction of adiposity and higher adiponectin levels, fasting blood sugar (FBS) was significantly higher than in CO + G-CR. Grape intake increased Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) expression and decreased insulin resistance in CO + G-CR. CONCLUSIONS: Sugar replacement with polyphenol-rich grape along with CR improved glucose homeostasis, and substituting corn oil with flaxseed oil in obese mice reduced fat mass, but even with no change in adiponectin levels it could not decrease insulin resistance. However, none of the food item combinations facilitated weight reduction in the long-term CR. Therefore, regardless of the total calorie intake, different diet components and fat contents may have unexpected effects on metabolic regulation.

Vitamin D Receptor Gene Polymorphisms, Metabolic Syndrome, and Type 2 Diabetes in Iranian Subjects: No Association with Observed SNPs.

OBJECTIVE: This study aimed to investigate the associations between metabolic syndrome and type 2 diabetes and the presence of single nucleotide polymorphism of the vitamin D receptor gene in Iranian subjects with type 2 diabetes. SUBJECTS AND METHODS: Overall, 730 Iranian subjects (372 patients and 358 controls) were enrolled in this case-control study. Single nucleotide polymorphisms of the vitamin D receptor gene (FokI, BsmI, ApaI, and TaqI) were genotyped using the restriction fragment length polymorphism method. The statistical difference in genotype distribution among the groups was assessed by χ2 test. Logistic regression was performed to calculate odds ratios for the association of the genotype frequencies in different groups with the risk of metabolic syndrome and type 2 diabetes. RESULTS: The most common genotypes for BsmI, ApaI, TaqI, and FokI were Bb, Aa, TT, and FF, respectively. Adjusted χ2 test revealed that there was no difference between the groups in the genotypes frequencies of 4 vitamin D receptor polymorphisms in type 2 diabetes subjects. On the other hand, type 2 diabetes subjects with Tt genotype presented a signifi cantly higher fasting blood glucose than those with TT and tt genotypes in TaqI polymorphisms (p = 0.009). Logistic regression showed no association between metabolic syndrome risk and vitamin D receptor genotypes. CONCLUSION: We found no evidence for the association between vitamin D receptor gene polymorphisms and the risk for type 2 diabetes and metabolic syndrome in Iranian subjects. Further examinations using genome-wide association in large prospective cohort studies are warranted.

Vitamin D receptor Cdx-2-dependent response of central obesity to vitamin D intake in the subjects with type 2 diabetes: a randomised clinical trial.

This study aimed to investigate the effects of daily intake of vitamin D-fortified yogurt drink (doogh) on central obesity indicators in subjects with type 2 diabetes (T2D) and the possible modulation of this effect by vitamin D receptor (VDR) Cdx-2 genotypes. A total of sixty T2D subjects were randomly allocated to two groups to receive either plain doogh (PD; n 29, containing 170 mg Ca and no vitamin D/250 ml) or vitamin D3-fortified doogh (FD; n 31, containing 170 mg Ca and 12·5 µg/250 ml) twice a day for 12 weeks. 25-hydroxyvitamin D (25(OH)D), glycaemic as well as adiposity indicators were evaluated before and after the intervention. VDR-Cdx-2 genotypes in extended number of T2D subjects in the FD group (n 60) were determined as AA, GA and GG. After 12 weeks, in FD compared with PD, serum 25(OH)D increased (+35·4 v. -4·8 nmol/l; P<0·001) and mean changes of waist circumference (WC; -1·3 v. +1·6 cm; P=0·02), body fat mass (FM; -1·9 v. +0·60 %; P=0·008), truncal fat (TF; -1·1 v. 0·13 %; P=0·003) and visceral adipose tissue (-0·80 v. +0·37 AU; P<0·001) decreased significantly. Circulating 25(OH)D was raised only in the AA group (34·8 nmo/l in AA group v. -6·4 nmol/l in AG and -1·6 nmol/l in GG groups; P<0·001), which was accompanied by a significant decrease in changes of WC (P=0·004), FM% (P=0·01) and TF% (P<0·001) in the AA genotype. Daily intake of vitamin D-FD for 12 weeks improved the central obesity indices in T2D subjects, and the improvement was more pronounced in the carriers of the AA genotype of VDR-Cdx-2.

Worse becomes the worst: obesity inequality, its determinants and policy options in Iran.

Background: This tracked obesity inequality and identified its determinants among the population of Iran. In addition, it examined the impact of implemented policies on these inequalities. Methods: This study was performed in two phases. First, we conducted a rapid review of the disparity in obesity prevalence in Iran. Then we investigated the main determinants of this inequality in a qualitative study. In addition, we examined Iran's policies to deal with obesity from the perspective of equality. We conducted 30 Semi-structured interviews with various obesity stakeholders selected through a purposive snowball sampling method between November 25, 2019, and August 5, 2020. In the inductive approach, we used the content analysis method based on the Corbin and Status framework to analyze the data using MAXQDA-2020. The consolidating criteria for reporting a Qualitative Study (COREQ-32) were applied to conduct and report the study. Results: Inequalities in the prevalence of obesity in terms of place of residence, gender, education, and other socioeconomic characteristics were identified in Iran. Participants believed that obesity and inequality are linked through immediate and intermediate causes. Inequality in access to healthy foods, physical activity facilities, and health care are the immediate causes of this inequality. Intermediate factors include inequality against women, children, and refugees, and inequality in access to information, education, and financial resources. Policymakers should implement equity-oriented obesity control policies such as taxing unhealthy foods, subsidizing healthy foods, providing healthy and free meals in schools, especially in disadvantaged areas, and providing nutrient-rich foods to low-income families. Also, environmental re-engineering to increase opportunities for physical activity should be considered. Of course, for the fundamental reduction of these inequalities, the comprehensive approach of all statesmen is necessary. Conclusion: Obesity inequality is a health-threatening issue in Iran that can prevent achieving human development goals. Targeting the underlying causes of obesity, including inequalities, must be considered.

The relationship between food habits and physical activity and the IQ of primary school children.

BACKGROUND: Children's intelligence quotient (IQ) is influenced by various environmental and genetic variables. The current study aimed to determine how children's dietary choices and physical activity levels correlated with their IQ. METHODS: A total of 190 students (111 girls and 79 boys) between the ages of 8 and 10 were chosen randomly for this cross-sectional research. For all children, questionnaires were utilized to gather information on their anthropometry, socio-economic position, food habits, and 24-h memory. Children's physical activity questionnaire (CPAQ) was also used to gauge their level of physical activity. Raven's color progressive intelligence test was also used to gauge children's IQ. All the questions may be filled out online with the assistance of parents. SPSS software was used to gather and evaluate the generated data. RESULTS: Of 190 respondents, 79 (41.6%) are males, and 111 (58.4%) are girls. The results of the study showed that, a positive correlation between children's IQ and physical activity (P = 0.017, r = 0.17), if this relationship was not seen by gender. In addition, a positive correlation was observed between the IQ and food habits scores in all children (P = 0.001, r = 0.24), as well as by gender, that is, male (P = 0.04, r = 0.23) and female (P = 0.006, r = 0.26), which indicates that children with better food habits were associated with higher IQ. CONCLUSION: It was shown that elementary school children's IQ, food habits, and degree of physical activity are all positively correlated.

Quercetin prevents experimental glucocorticoid-induced osteoporosis: a comparative study with alendronate.

Glucocorticoid-induced osteoporosis (GIO) is the most common type of secondary osteoporosis. The aim of this study was to compare the efficacy of quercetin, a plant-derived flavonoid, with alendronate in the prevention of GIO. Fifty-six Sprague-Dawley rats were randomly distributed among 7 groups (8 rats per group) and treated for 6 weeks with one of the following: (i) normal saline; (ii) 40 mg methylprednisolone sodium succinate (MP)/kg body mass; (iii) MP + 40 µg alendronate/kg; (iv) MP + 50 mg quercetin/kg; (v) MP + 40 µg alendronate/kg + 50 mg quercetin/kg; (vi) MP + 150 mg quercetin/kg; and (vii) MP + 40 µg alendronate/kg + 150 mg quercetin/kg. MP and alendronate were injected subcutaneously and quercetin was administered by oral gavage 3 days a week. At the end of the study, femur breaking strength was significantly decreased as a consequence of MP injection. This decrease was completely compensated for in groups receiving 50 mg quercetin/kg plus alendronate, and 150 mg quercetin/kg with or without alendronate. Quercetin noticeably elevated osteocalcin as a bone formation marker, while alendronate did not show such an effect. In addition, administration of 150 mg quercetin/kg increased femoral trabecular and cortical thickness by 36% and 22%, respectively, compared with the MP-treated group. These data suggest that 150 mg quercetin/kg, alone or in combination with alendronate, can completely prevent GIO through its bone formation stimulatory effect.

Therapeutic effects of vitamin D as adjunctive therapy to fluoxetine in patients with major depressive disorder.

OBJECTIVE: To compare the therapeutic effects of vitamin D3 plus fluoxetine and fluoxetine alone in patients with major depressive disorder. METHODS: In the present double-blind, randomized, placebo-controlled trial, 42 patients with a diagnosis of major depressive disorder based on DSM-IV criteria were randomly assigned into two groups to receive daily either 1500 IU vitamin D3 plus 20 mg fluoxetine or fluoxetine alone for 8 weeks. Depression severity was assessed at 2-week intervals using the 24-item Hamilton Depression Rating Scale (HDRS) as a primary outcome measure and the 21-item Beck Depression Inventory (BDI) as a secondary outcome measure. Serum 25(OH) vitamin D was measured at baseline and after intervention. RESULTS: Forty patients completed the trial. A two-way repeated-measures analysis of variance showed that depression severity based on HDRS and BDI decreased significantly after intervention, with a significant difference between the two groups. The vitamin D + fluoxetine combination was significantly better than fluoxetine alone from the fourth week of treatment. CONCLUSIONS: In the present 8-week trial, the vitamin D + fluoxetine combination was superior to fluoxetine alone in controlling depressive symptoms.

The relationship between food cravings and body image with healthy eating index in adolescent girls.

OBJECTIVES: Adolescence is one of the most critical phases in any individual's life; adolescent nutrition is closely tied to physical health and development. Research has found that adolescent girls are particularly vulnerable to body image concerns and disordered eating behaviors, making it crucial to understand the factors that contribute to these issues. The relationship between food cravings, body image, and healthy eating behaviors is complex and multifaceted and requires careful investigation to identify effective interventions that can promote healthy eating habits in adolescent girls. By exploring the connections between these variables, researchers and health care professionals can develop targeted strategies to reduce food cravings, improve body image, and encourage healthy eating behaviors. Ultimately, this can have important implications for promoting adolescent health and reducing the risk of chronic diseases in later life. METHODS: This cross-sectional study was conducted on 161 students, ages 15 to 18 y. Data on dietary intake, physical activity, food cravings, and body image were collected using valid standard questionnaires. Data were analyzed using analysis of variance, Kruskal-Wallis, Spearman, and linear regression tests in SPSS software. RESULTS: The mean age of the participants was 15.94 ± 0.93 y. The participants' mean height, weight, and body mass index (BMI) were 160.78 ± 5.28 cm, 56.45 ± 11.03 kg, and 21.79 kg/m2, respectively. The z score of height for age in the studied samples was -0.22 ± 0.77, and BMI for age was 0.17 ± 1.15 kg/m2. Most participants followed diets that needed to be modified. The healthy eating index (HEI) among them was 53.0.6 ± 9.51. Also, a significant and direct correlation was observed between body image and HEI (P = 0.01) after adjusting for confounding variables. The HEI did not reveal a significant relationship with food cravings even with the modification of confounders (P = 0.18). Moreover, no significant connection was identified between HEI and BMI (P = 0.51). CONCLUSIONS: Adolescents with higher body image score had better nutritional quality. Moreover, food cravings and BMI did not have any relationship with HEI score.

Association Between Infants Anthropometric Outcomes With Maternal AHEI-P and DII Scores.

The present study sought to examine the association between an infant's anthropometric outcomes with maternal Dietary Inflammatory Index (DII) and Alternate Healthy Eating Index for Pregnancy (AHEI-P) scores during the third trimester of pregnancy. This prospective cohort study was applying 130 pregnant women, at the pregnancy training center in west Tehran, Iran (November 2020 to July 2021). The maternal dietary intake, and body mass index (BMI), and social economic level were evaluated. The data about birth weight, birth height, head circumference, and, gestational age at birth were extracted from each child's health records. The ultimate sample included 122 (93.8%) pairs of women/newborn children. The participants, mean age was 28.13 ± 4.66 years with gestational age between 28 to 40 weeks and the mean of BMI was 24.62 ± 3.51. Our outcomes, after adjustment for confounding factors, suggested that those newborn infants in the highest quartile of maternal DII score had a significantly lower weight (p < 0.001) and height (p = 0.05), in comparison to those in the lowest quartile, but not head circumference (p = 0.18). Moreover, after adjustment for confounding factors, results suggested that those newborn infants in the First quartile of maternal AHEI-P score had a significantly lower weight (p = 0.018) and, in comparison to those in the higher quartile. It appears that newborn infants with lower maternal DII and higher AHEI-P scores may have a better anthropometric outcome. Further longitudinal and in-depth qualitative and quantitative studies, with a longer-term follow-up, is warranted to support the integrity of our outcomes.

Double burden of malnutrition in Afghanistan: Secondary analysis of a national survey.

BACKGROUND: Reports about the magnitude of co-existence of under- and over-nutrition is limited in Afghanistan. This study aimed to assess the prevalence of double burden of malnutrition (DBM) at individual and household level in Afghanistan. METHODS: This study was done based on the Afghanistan National Nutrition Survey 2013, which included a representative sample of 126,890 individuals (including more than 18,000 households) throughout Afghanistan. Intra-individual DBM was defined as the co-existence of "overweight/obese" and "stunting or micronutrient deficiencies" (including anemia, vitamin A deficiency, vitamin D deficiency and iodine deficiency). At the household level, DBM was considered as having at least one household member as overweight/obese and at least one another member of that household as undernourished (stunted, wasted, underweight or any micronutrient deficiency). SPSS and Stata software were used in the current analysis. Cross-tabulations was used to estimate the prevalence and its 95% confidence interval(CI). This study was ethically approved at Tehran University of Medical sciences. RESULTS: The overall prevalence of intra-individual DBM was 12.5% (95% CI: 12.1; 12.9). Among the whole study participants at individual level of DBM, 11.7% (11.3; 12.1) of individuals had overweight along with stunting simultaneously and 20.5% (18.8; 22.4) had overweight and micronutrient deficiencies at the same time at individual level. The household level of DBM was found among 28.6% (95% CI: 27.9; 29.4) of households; such that 27.3% (26.6; 28.1) of households had at least one member with overweight and another member with stunting or wasting or underweight. Co-existence of overweight and micronutrient deficiencies at the same household was seen in 38.3% (35.5; 41.2). CONCLUSION: This study demonstrated a high prevalence of DBM at individual and household level in Afghanistan. Therefore, developing appropriate national macro-policies and strategies and designing appropriate programs such as public awareness programs, subsidization, food assistance programs, food fortification and dietary supplementation should be implemented by the ministry of public health, inter- related organs and international health agencies to reduce the burden of this problem in this country.

Improvement of vitamin D status resulted in amelioration of biomarkers of systemic inflammation in the subjects with type 2 diabetes.

BACKGROUND: Both vitamin D deficiency and inflammation have been linked to cardiovascular disease, the major cause of death in diabetes. In this study, the effects of daily intake of vitamin D-fortified yoghourt drink (doogh) on systemic inflammatory biomarkers in subjects with type 2 diabetes (T2D) were investigated. SUBJECTS AND METHODS: In this 12-week randomized controlled trial, T2D subjects received either plain doogh (PD; containing 170 mg calcium and no detectable vitamin D/250 mL, n(1) = 50) or vitamin D3-fortified doogh (FD; containing 170 mg calcium and 500 IU/250 mL, n(2) = 50) twice a day. Glycemic status, body fat mass and systemic inflammatory biomarkers including serum highly sensitive C-reactive protein (hsCRP), serum amyloid A (SAA), interleukin(IL)-2, IL-6, IL-10 and tumour necrosis factor (TNF)-α were evaluated at the beginning and after the intervention. Data were expressed as either mean ± SD or median (interquartile range) whenever they had either normal or non-normal distribution, respectively. RESULTS: In the patients receiving the vitamin D fortified drink, compared with those receiving the unfortified drink, a significant increase in serum 25(OH)D was accompanied by significant changes in TNF-α (-57.9 (-264.6) versus +106.3 (683.2), p = 0.044), IL-6 (-6.3 (-69.2), p = 0.002), hsCRP (-0.39 (-1.50) versus +0.8 (1.52), p < 0.001), SAA (-14.2 ± 44.5 versus +5.6 ± 37.5 mg/L, p = 0.022) and IL-10 (+38.7 ± 157.0 versus -51.9 ± 165.2 ng/L, p = 0.013). The between-group differences of hsCRP, SAA and IL-6 changes remained significant even after controlling for changes quantitative insulin check index (p < 0.001, p < 0.001 and p = 0.009, respectively). CONCLUSIONS: Improvement of vitamin D status of T2D subjects resulted in amelioration of the systemic inflammatory markers. This may have preventive implications against cardiovascular disease and other diabetic complications.

The relationship between dietary sulfur amino acids intake and severity and frequency of pain in Iranian patients with musculoskeletal pains, 2020.

OBJECTIVE: Musculoskeletal pain conditions (MPs) are a widespread public problem that can affect 13.5% to 47% of the total population. Dietary changes can have strong effects on person's health; for instance, Sulfur amino acids (SAAs) can act as a precursor of neurotransmitters, antioxidative metabolic intermediates, such as glutathione, impact inflammation, and play a role in severity and frequency of MPs. We evaluated the relationship between dietary SAAs intake with severity and frequency of pain in patients with MPs. RESULTS: This cross-sectional study consisted of 175 men and woman. Anthropometric measurements and pain assessments were conducted via questionnaires. Dietary data were collected using 7 days 24-h recall. ANOVA and Spearman correlation coefficients were used to examine the relationship and correlation, respectively, between exposure and outcome variables. There was a significant correlation between age, weight, waist circumference (WC), waist circumference to height (WHtR), body mass index (BMI), and severity and frequency of MPs among women. There was a correlation between age and severity of pain in men. The present study highlights a positive association between the dietary SAAs and severity of pain, even after adjusting for confounding variables.

The association between meal-based diet quality index-international (DQI-I) with obesity in adults.

BACKGROUND AND OBJECTIVE: Due to the growing global trend of obesity, it is necessary to study the diet quality as a modifiable factor to reduce the dangerous consequences of obesity. Therefore, the aim of this study was to evaluate the association between meal-based diet quality index-international (DQI-I) with obesity in adults. METHODS: This cross-sectional study was performed on 850 men and women in Tehran (aged 20-59 y). Dietary intakes were assessed using three 24-h dietary recalls. Meal-based Diet quality was assessed based on the construction of DQI-I. The total DQI-I score ranged from 0 to 100, with higher scores denoting better diet quality. Multiple linear regression analysis was used to examine the association of DQI-I and BMI in each meal and Logistic regression analysis was used to examine the association of DQI-I and obesity in each meal. RESULTS: The mean (± SD) of age, body mass index (BMI), waist circumference (WC) and waist to hip ratio (WHR) were 42.35(± 10.90) years, 27.32(± 5.61) kg/m2, 89.09 (± 12.04) cm and 0.86 (± 0.11), respectively. In none of the meals, after adjusting for confounders, no significant difference in BMI was observed in the both women and men groups. After controlling of confounders, there was not any relationship between meal-based DQI-I and BMI resulted from multiple linear regression analysis also there was not any significant association between meal-based DQI-I and obesity resulted from Logistic regression analysis. CONCLUSION: In this study, we did not find any significant association between meal-specified DQI with obesity. To reach the better evaluation, more prospective studies with large sample size are needed.
