Meat and dairy products intake is associated with gastric cancer: Case-control study findings.

Countries experiencing a significant shift toward Western lifestyle are facing an increased risk of gastric cancer (GC). While many studies have explored the link between diet and GC, the role of meat and dairy consumption remains uncertain. To delve deeper into this association, we conducted a case-control study in Jordan involving 173 GC cases and 314 controls, matched by age and marital status. Using a validated food frequency questionnaire, we assessed the intake of different dairy and meat products. The adjusted odds ratios and corresponding 95% confidence intervals indicated a strong correlation between high intake of red meat, milk, and buttermilk and GC. Our multinomial logistic regression analysis revealed that daily consumption of red meat (≥1 serving/day; OR, 3.34 [95% CI 1.85-6.03, p value of trend <.001], ≥1 serving/day) and weekly intake of milk (2-3 servings/week; OR, 2.04 [95% CI 1.14-3.64, p value of trend = .041]) and buttermilk (2-3 servings/week; OR, 2.07 [95% CI 1.12-3.83, p value of trend = .018], per 2-3 servings/week) were significantly associated with an increased risk of GC. Furthermore, consuming cooked eggs daily (OR = 2.44, 95% CI 1.24-4.79, p trend <.001) or weekly (OR, 3.34, 95% CI 1.58-7.10, p value of trend <.001) was also associated with an increased risk of GC. These findings highlight the potential health risks associated with excessive meat and some dairy products consumption and suggest that a balanced intake of these products, along with eggs, may help prevent GC.

Does probiotic supplementation improve quality of life in mild-to-moderately active ulcerative colitis patients in Jordan? A secondary outcome of the randomized, double-blind, placebo-controlled study.

PURPOSE: Recent findings revealed a potential effect of a probiotic in improving quality of life (QoL) in ulcerative colitis (UC). In Jordan, there is scarce data about UC patients and QoL. METHODS: Twenty-four UC patients were included in the study and were randomly allocated into probiotic (3 × 1010 probiotic capsules containing nine Lactobacillus and five Bifidobacterium species) and placebo control groups (containing polysaccharide supplied in an identical bottle) 3 times daily/6 weeks. A short inflammatory bowel disease questionnaire (SIBDQ) was used to assess the change in the quality of life in both groups at the beginning and the end of the intervention; The study was completed during the COVID-19 pandemic. RESULTS: Patients treated with probiotics showed a higher score of social (6.92 ± 0.29, p = 0.019), bowel (6.31 ± 0.46, p = 0.001), emotional (6.47 ± 0.46, p < 0.001), and total SIBDQ scores (6.54 ± 0.29, p < 0.001) compared to the placebo group (5.75 ± 1.57, 4.72 ± 1.34, 4.42 ± 1.67 and 4.96 ± 1.27; respectively). Also, the probiotic group had significantly better scores in the systemic, social, bowel, emotional, and total SIBDQ scores in terms of pre- to post-treatment (p < 0.001). CONCLUSIONS: The use of probiotic therapy containing Lactobacillus and Bifidobacterium species had significantly improved the quality of life among UC patients, this was shown by the improvement in the scores of the systemic domain, social domain, bowel domain, emotional domain, and total SIBDQ. This study is part of a registered study at ClinicalTrials.gov with the number NCT04223479.

Does the Mediterranean Diet Have Any Effect on Lipid Profile, Central Obesity and Liver Enzymes in Non-Alcoholic Fatty Liver Disease (NAFLD) Subjects? A Systematic Review and Meta-Analysis of Randomized Control Trials.

The effectiveness of the Mediterranean diet (MD) in non-alcoholic fatty liver disease (NAFLD) subjects has been evaluated in several randomized controlled trials (RCTs). This systematic review and meta-analysis aimed to evaluate the overall effects of MD intervention in a cohort of NAFLD patients targeting specific markers such as central obesity, lipid profile, liver enzymes and fibrosis, and intrahepatic fat (IHF). Google Scholar, PubMed, and Scopus were explored to collect relevant studies from the last 10 years. RCTs with NAFLD subjects were included in this systematic review with a mean intervention duration from 6 weeks to 1 year, and different intervention strategies, mainly including energy restriction MD (normal or low glycaemic index), low-fat MD with increased monounsaturated and polyunsaturated fatty acids, and increased exercise expenditure. The outcomes measured in this meta-analysis were gamma-glutamyl transferase (GGT), alanine aminotransferase (ALT), total cholesterol (TC), waist circumference (WC), and liver fibrosis. Ten randomized controlled trials, which involved a total of 737 adults with NAFLD, were included. According to the results, the MD seems to decrease the liver stiffness (kPa) by -0.42 (CI95% -0.92, 0.09) (p = 0.10) and significantly reduce the TC by -0.46 mg/dl (CI95% -0.55, -0.38) (p = 0.001), while no significant findings were documented for liver enzymes and WC among patients with NAFLD. In conclusion, the MD might reduce indirect and direct outcomes linked with NAFLD severity, such as TC, liver fibrosis, and WC, although it is important to consider the variations across trials. Further RCTs are necessary to corroborate the findings obtained and provide further evidence on the role of the MD in the modulation of other disorders related to NAFLD.

Dietary Management of Type 1 Diabetes Mellitus with Celiac Disease.

Celiac disease is diagnosed more commonly with type 1 diabetes, and the most problematic aspect for a child with type 1 diabetes and celiac disease is that most GFD foods have a high glycemic index, while low glycemic index foods are recommended for type 1 diabetes mellitus. As a result, dietary controls become more difficult. Diet management could improve the elevated HbA1c levels. The aim of this review is to illustrate the clinical features and diagnostic considerations, as well as current knowledge of common pathogenic features such as genetics, environmental risk factors, and the gut microbiome of type 1 diabtes and celiac disease. Also, the importance of diet management on glycemic control and growth rate in patients with type 1 diabetes mellitus and celiac disease has been discussed. PubMed and Google Scholar databases were searched. Reports published from the years 1969 to 2021 focused on the role of type 1 diabetes mellitus and celiac disease, and examined the types of diet on glycemic control, growth rate, and quality of life. Only a few studies on the effects of a carbohydrate count gluten-free diet on glycemic control, growth rate, and quality of life in patients with type 1 diabetes mellitus and celiac disease have been conducted. There have been few studies showing that dietary intervention helps to achieve and maintain normal blood glucose and blood pressure levels, a healthy lipid profile, and a healthy body weight. Studies stated that a low-carbohydrate diet had the greatest effect on improving glycemic control and insulin parameters.

Effects of different diets on glycemic control among patients with type 2 diabetes: A literature review.

Background: Globally, type 2 diabetes mellitus (T2DM) is one of the most common diseases, and the incidence is gradually increasing. Diet management could improve the elevated HbA1c levels. Aim: This review aims to examine the effects of different types of diets on glycemic control in patients with T2DM. Methods: PubMed and Google scholar databases were searched. Reports published from the years 1991 to 2021 that focused on the effect of different diets on diabetes control were selected. Results: All the studies reported that the type of diet can affect insulin secretion and glycemic control in patients with diabetes. The recommended macronutrient distribution for patients with diabetes is 30% of fat, 45-60% of carbohydrates, and 15-35% of protein. Consuming more or less of these macronutrients may lead to changes in glucose metabolism and may affect insulin secretion. In fact, following alow-fat diet improves glycemic control and decreases HbA1c levels. Studies reported that a low-carbohydrate diet had the greatest effect on improving glycemic control and insulin parameters. A low-calorie diet reduced fasting plasma glucose, while a very low-calorie diet resulted in a long-term decrease in HbA1c level. A healthy diet free of processed foods and sugar, and rich in nutrients such as fiber, vitamins, and minerals contributed to maintaining controlled blood sugar and lipid plasma levels. Although studies show a low-salt diet improves blood pressure, which is common inT2DM, other findings show that restricting salt intake is associated with increased sugar consumption. Conclusion: Healthy diet with adequate intake of energy and low-fat and low-sugar foods can enhance the glycemic control and reduce T2DM complications.

Macronutrients Intake and Risk of Stomach Cancer: Findings from Case-Control Study.

Studies on the association between gastric cancer (GC) and the intake of nutrients in Jordan are very limited, while findings from other reports on the intake of energy and macronutrients are controversial. This study aimed to examine the associations between intake of energy and macronutrients and the risk of GC in a Jordanian population. A case-control study was carried out between March 2015 and August 2018 in four major hospitals, including an oncology center in Jordan. Study participants were 173 cases with incident and histologically confirmed GC and 314 frequency-matched controls. Interview-based questionnaires were used to obtain the study's information. Data on nutrient intake were collected using a validated Arabic food-frequency questionnaire (FFQ). Odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) were calculated through multinomial logistic regression and adjusted for potential confounders, including age, marital status, education, body mass index (BMI), smoking, period of smoking, family history of gastric cancer, history of gastric ulcer, and physical activity. Intakes of total fat, saturated fat, monounsaturated fat, polyunsaturated fat, cholesterol, trans-fat, and omega-6 fatty acids were significantly associated with increased risk of GC. The ORs for the highest versus the lowest tertiles were 6.47 (95% Cl: 3.29-12.77), 2.97 (95% CI: 1.58-5.58), 6.84 (95% CI: 3.46-13.52), 6.19 (95% CI: 3.15-12.17), 3.05 (95% CI: 1.58-5.88), 8.11 (95% CI: 4.20-15.69), and 2.74 (95% CI: 1.47-5.09), respectively. No significant association was found for energy, protein, carbohydrate, sugar, fibers, and omega-3 fatty acids. The findings of this study suggest that high intake of selected types of fats was associated with an increased risk of GC.

Macronutrients Not Micronutrients Are Associated With the Risk of Pancreatic Cancer: A Jordanian Case-Control Study.

OBJECTIVES: Pancreatic cancer (PC) has been related directly to many risk factors; however, diet is considered one of the most modifiable risk factors. This study is designed to observe the associations between the intake of macromicronutrients and the risk of pancreatic cancer in a Jordanian population. METHODS: A case-control study included 100 patients with the incident and histologically confirmed PC and 309 control subjects frequency-matched on age, educational level, occupation, and marital status. Face-to-face interview was used to collect the study's sociodemographic, physical activity, and dietary information. Intakes of macronutrients and micronutrients were assessed by a validated food-frequency questionnaire. Multinomial logistic regression was used to calculate odds ratios and confidence intervals. RESULTS: The patients reported higher consumption of almost all the macromicronutrients and micronutrients as compared with control subjects. The highest tertile of dietary intake of carbohydrates, sugars, fats, saturated fats, monounsaturated fats, trans fats, cholesterol, and vitamin B3 was positively associated with PC risk (Ptrend < 0.05). However, dietary intakes of polyunsaturated fats, omega-3, and some vitamins and minerals were not associated (Ptrend > 0.05) with the risk of PC. CONCLUSIONS: Our findings support the positive role of proteins, carbohydrates, sugars, fats, saturated fats, monounsaturated fats, trans fats, and cholesterol on pancreatic carcinogenesis.

Relative validity and reproducibility of a food frequency questionnaire to evaluate food group intakes among Jordanian children and adolescents / Validez relativa y reproducibilidad de un cuestionario de frecuencia alimentaria para evaluar la ingesta de grupos de alimentos entre niños y adolescentes jordanos

Introduction: studies of the impact of diet on the prevention and occurrence of diseases in all life stages require a reliable and valid dietary assessment tool for assessing dietary intake. Objectives: this study aimed to develop and evaluate the relative validity and reproducibility of a culturally sensitive quantitative food frequency questionnaire (FFQ) to assess food group intake among Jordanian children and adolescents. Methods: the validation study was carried out on 136 children and adolescents aged between 6 and 18 years who enrolled from selected public and private schools. Fifty of these children and adolescents participated in the reproducibility phase. Food group intake from a quantitative FFQ was compared with food group intake from 24-hour dietary recalls (24h-DRs). Four 24-HRs were collected weekly for one month. Results: intraclass correlation coefficients between the two FFQs ranged from 0.18 for nuts to 0.98 for tea. De-attenuated and energy-adjusted correlations ranged from 0.08 for nuts to 0.95 for vegetable oils. On average, 46.6 % and 43.6 % of participants were ranked by the FFQ-1 and the 24h-DRs into the same quartile based on their crude and energy-adjusted food group intake, respectively. Bland-Altman plots showed a satisfactory agreement between the two methods for milk and milk products and vegetables. Conclusions: the findings of this study suggested that the developed FFQ has excellent reproducibility and good relative validity for most food groups. (AU)

Se recogieron cuatro recordatorios de 024 horas semanales durante un mes. Resultados: los coeficientes de correlación intraclase entre los dos CFC variaron de 0,18 para las nueces a 0,98 para el té. Las correlaciones atenuadas y ajustadas por energía variaron de 0,08 para las nueces a 0,95 para los aceites vegetales. En promedio, el 46,6 % y el 43,6 % de los participantes fueron clasificados por el CFC-1 y el 24h-DR en el mismo cuartil en función de la ingesta de grupo de alimentos crudos y ajustados por energía, respectivamente. Los gráficos de Bland-Altman mostraron una concordancia satisfactoria entre los dos métodos para la leche y los productos lácteos y las hortalizas. Conclusiones: los hallazgos de este estudio sugirieron que el CFC desarrollado tiene una excelente reproducibilidad y una buena validez relativa para la mayoría de los grupos de alimentos. (AU)

Dietary inflammatory index and odds of breast cancer: A case-control study.

Breast cancer (BrCA) is one of the most commonly diagnosed cancers and is the leading cause of cancer deaths in women worldwide. This study aimed to examine the association between the dietary inflammatory index (DII®) and BrCA among Jordanian women. A total of 400 adult women were enrolled into this case-control study. Cases were 200 women recently diagnosed with BrCA selected from the two hospitals that provide cancer therapy in Jordan. They were matched on age, income, and marital status with 200 BrCA-free controls. DII scores were calculated from dietary data that were collected in a face-to-face interview conducted between October 2016 and September 2017 using a validated food frequency questionnaire. Conditional logistic regression models were used to calculate odds ratios (ORs) and 95% CIs. The study results revealed no significant associations between DII scores in relation to the odds of developing BrCA after multivariable adjustment including age, education, total energy, BMI, number of pregnancy, contraceptive use, lactation, smoking, and family history of BrCA. Stratified analyses by obesity status showed that overweight/obese participants in the highest DII tertile had a >75% increased BrCA risk (OR of 1.77 [95% CI, 1.01-3.12]) compared with participants in the lowest tertile, after adjusting for age. The results from this study showed no significant relationship between the proinflammatory potential of the diet and BrCA risk in the overall study population. However, results stratified by weight category indicated an effect of diet-associated inflammation on BrCA risk in the overweight/obese group. Results of the study are consistent with a recommendation aimed at maintaining higher diet quality, that is, adopting healthy diets characterized by low DII scores in order to reduce the risk for BrCA.

COVID-19 Vaccine Hesitancy in a Representative Education Sector Population in Qatar.

Even though vaccination programs have now started in earnest across the globe and in Qatar, vaccine hesitancy remains a barrier to effectively tackling the pandemic. Many factors influence willingness to take vaccines including safety, efficacy, and side effects. Given their proximity to research and education, university students and employees represent an interesting cohort in which to investigate vaccine hesitancy. The aim of this study was to assess the attitudes of Qatar University employees and students towards the COVID-19 vaccine. In total, 231 employees and 231 students participated in an online cross-sectional study in February 2021. Of the sample, 62.6% were willing to take a vaccine against COVID-19. Participants with or taking postgraduate degrees were more willing to take the vaccine compared to participants with or taking a diploma or bachelor's degree (p < 0.001). Males had a higher rate of vaccine acceptance (p < 0.001). In the group that regarded flu vaccination as important, 13% were unwilling to take COVID-19 vaccine. There were no associations between willingness to vaccinate and vaccine/virus knowledge and social media use. Participants showed a high level of concern regarding vaccine side effects in themselves or their children. Two-thirds agreed or strongly agreed that they would take the vaccine if it was mandatory for international travel. Our participants were neutral to the origin of vaccine development. These findings, which represent data collected after the start of the national vaccination program, show that vaccine hesitancy persists in the Qatari population and that some groups, such as undergraduate students, could benefit from specific, targeted public health campaigns.

Dietary Patterns and the Risk of Inflammatory Bowel Disease: Findings from a Case-Control Study.

Scientific evidence shows that dietary patterns are associated with the risk of IBD, particularly among unhealthy and Western dietary patterns. However, Western dietary patterns are not exclusive to Western countries, as Jordanians are steadily moving towards a Western lifestyle, which includes an increased consumption of processed foods. This study aims to investigate the association between dietary patterns and the risk factors for IBD cases among Jordanian adults. This case-control study was conducted between November 2018 and December 2019 in the largest three hospitals in Jordan. Three hundred and thirty-five Jordanian adults aged between 18-68 years were enrolled in this study: one hundred and eighty-five IBD patients who were recently diagnosed with IBD (n = 100 for ulcerative colitis (UC) and n = 85 for Crohn's disease (CD)) and 150 IBD-free controls. Participants were matched based on age and marital status. In addition, dietary data was collected from all participants using a validated food frequency questionnaire. Factor analysis and principal component analysis were used to determine the dietary patterns. Odds ratios (OR) and their 95% confidence interval (CI) were calculated using a multinomial logistic regression model. Two dietary patterns were identified among the study participants: high-vegetable and high-protein dietary patterns. There was a significantly higher risk of IBD with high-protein intake at the third (OR, CI: 0.136 (0.068-0.271)) and fourth (OR, CI: 0.126 (0.064-0.248)) quartiles in the non-adjusted model as well as the other two adjusted models. In contrast, the high-vegetable dietary pattern shows a significantly protective effect on IBD in the third and fourth quartiles in all the models. Thus, a high-vegetable dietary pattern may be protective against the risk of IBD, while a high-protein dietary pattern is associated with an increased risk of IBD among a group of the Jordanian population.

Lifestyle and Dietary Factors Associated with Inflammatory Bowel Disease among Jordanian Patients.

BACKGROUND AND AIMS: Inflammatory bowel diseases (IBD) affect Jordanian adults more than other age groups. Several studies highlight the independent effect of various lifestyle factors on the risk of IBD. Therefore, this study aims to compare the differences between some lifestyle factors among IBD cases and IBD-free controls, while detecting the varying degree of malnutrition in the study sample. METHODS: A case-control study was conducted between November 2018 and December 2019. Three hundred and thirty-five Jordanian adults above the age of 18 years were enrolled in this study. Out of the 335 participants, 185 of them were recently diagnosed with IBD [100 ulcerative colitis (UC) and 85 Crohn's disease (CD)] and 150 IBD-free controls. Sociodemographic characteristics, anthropometric measurements, dietary habits and the degree of malnutrition using the Patient-Generated Subjective Global Assessment (PG-SGA) were collected from all participants. RESULTS: Body mass index and waist circumference were significantly different in UC patients as compared to controls. Cigarette smoking, work status, duration of sleeping hours, physical activity, number of daily main meals intake, meals skipped daily, number of daily snack meal intake, and fast-food intake were all significantly different when comparing IBD cases to controls. While cigarette smoking (OR=0.52, 95%CI: 0.29-0.96, p=0.02) and sleep duration hours during working day (OR=0.05, 95%CI: 0.01-4.68, p=0.001)] were found to be protective factors, the increase in daily working hours (OR=22.13, 95%CI: 10.35-47.32, p=0.001) was identified as a risk factor for IBD. The degree of moderate and severe malnutrition among patients with IBD was significantly (p<0.001) higher as compared to controls. CONCLUSIONS: Patients with IBD had lower BMI and physical activity values compared to controls. The number of daily main meals intake, meals skipped daily, number of daily snack meals intake, fast food intake and the degree of malnutrition were significantly different when IBD cases were compared to controls.

Development and validation of a food frequency questionnaire for assessing nutrient intake during childhood in Jordan / Desarrollo y validación de un cuestionario de frecuencia alimentaria para evaluar la ingesta de nutrientes durante la infancia en Jordania

INTRODUCTION: assessing the relationship between childhood diseases and nutrient intake is a crucial issue that requires valid and reliable dietary assessment tools in this period of physical and physiological development. OBJECTIVE: the present study aimed to develop and validate a food frequency questionnaire (FFQ) to assess nutrient intake in Jordanian children. METHODS: in this validation study, nutrient intake as obtained from a culturally sensitive quantitative FFQ was compared to nutrient intake as assessed by four 24-hour dietary recalls (24-HRs) between September 2017 and May 2018. One hundred and thirty-six children aged 6-18 years were enrolled from selected schools in Amman, Jordan. Children or their caregivers were asked to complete the FFQ during an initial face-to-face interview. Four 24-HRs were collected weekly over one month. Of these children, 50 also took part in the reproducibility phase, which involved a repeat completion of the FFQ within 1 month. RESULTS: the intraclass correlation coefficients between the two FFQs ranged from 0.5 for trans-fats to 0.96 for calcium. Correlation coefficients between dietary intake estimates derived from the FFQ and 24-HRs were significant at p < 0.05. The highest correlation was detected for energy (0.8) while the lowest was identified for trans-fatty acids (0.04). For all nutrients, over 60 % of participants were classified into the same or adjacent quartile of crude and adjusted intake. Bland-Altman plots showed a satisfactory agreement between the two methods for energy and proteins. CONCLUSION: the FFQ showed a good reproducibility and a reasonable relative validity for most nutrients

Fruit and vegetable consumption and cardiovascular diseases among Jordanians: a case-control study.

OBJECTIVES: Fruit and vegetable intake has been reported as one of the significant protective factors against the development of cardiovascular diseases (CVD). This study aimed to assess the possible preventive effect of fruit and vegetable consumption on developing CVD. METHODS: A total of 398 participants (205 cases and 193 controls) referred for elective coronary angiography with clinical suspicion of coronary artery disease to Prince Hamza Hospital in Amman were enrolled in this case-control study. Dietary data were collected separately from each patient using interview-based food frequency questionnaire. RESULTS: The findings of the present study revealed that a total consumption of 3 servings of vegetable per day decreased significantly the risk of CVD to about 54% (OR = 0.46, 95% CI: 0.22-0.97, p = 0.033). Consumption of banana was found to reduce the risk of CVD to about 44% and 62% when consuming 1-2 and 3-6 servings/week, respectively, with p-value for trend 0.004. For the vegetables, the consumption of grape leaves and stuffed vegetables in general was significantly associated with lower risk of CVD. Increasing cauliflower consumption of 1-2 servings per week decreased CVD risk to about 37% (OR = 0.63, 95% CI: 0.38-0.98). Consuming up to 3-6 servings per week of mixed vegetables (OR = 0.10, 95% CI: 0.01-0.83) and onion (OR = 0.42, 95% CI: 0.22-0.80) revealed an inverse association with CVD development. CONCLUSIONS: Adding to the present evidence, consumption of some fruits and vegetables could be considered as preventive factor against developing CVD. However, the association of consuming vegetables with preventing CVD was higher than the fruit consumption.

Relationship between dietary sodium and sugar intake: A cross-sectional study of the National Health and Nutrition Examination Survey 2001-2016.

Dietary sodium intake and cardiovascular outcomes have a reported J-shaped curve relationship. This study analyzes the relationship between dietary sodium and sugar intake as a potential mechanism to explain this association. The authors examined cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) 2001-2016 where dietary sodium, carbohydrate, fat, cholesterol, and sugar intakes were assessed by 24-hour dietary recall and were standardized to a total daily intake of 2000 calories. Sodium intake was categorized into sodium quintiles (SQ) as follows: SQ1(0.06-2.6 g/d); SQ2(2.6-3.0 g/d); SQ3(3.0-3.4 g/d); SQ4(3.4-4.0 g/d); and SQ5(4.0-29.3 g/d). Simple and multivariate linear regression using SQ3 as reference were used to assess associations between daily sodium intake and the other nutrients. Our results showed that among 38 722 participants that met our study criteria, the mean age was 43.6 years (SD 16.8 years) and sex was equally distributed (48.8% male vs 51.2% female). Sugar intake went down across increasing SQs and was significantly higher in SQ1 (141.2 g/d) and SQ2 (118.6 g/d) and significantly lower in SQ4 (97.9 g/d) and SQ5 (85.6 g/d) compared to SQ3 (108.6 g/d; all P < .01). These same trends remained unchanged and significant in the fully adjusted multivariate model. In conclusion, NHANES study participants reporting low sodium intake on 24-hour dietary recall have a higher consumption of sugar. The negative impact of low sodium diet on cardiovascular health may be explained at least partially by the associated high sugar intake.

Fat intake and the risk of coronary heart disease among Jordanians / La ingesta de grasas y el riesgo de enfermedad coronaria de los jordanos

INTRODUCTION: dietary fat has been reported as one of the significant risk factors in the development of cardiovascular diseases (CVD). OBJECTIVE: this study aimed at assessing the possible association between fat intake and CVD. METHODS: the present case-control study was conducted in the center of coronary angiography. Three-hundred and ninety nine patients who referred for elective coronary angiography with clinical suspicion of coronary artery disease were enrolled. Dietary data were collected from each patient using an interview-based food frequency questionnaire. RESULTS: the findings of the present study revealed no significant differences between cases and controls regarding the intake of all types of fat either before or after energy adjustment. For both cases and controls the percentage of fat intake from total energy and the intakes of polyunsaturated and monounsaturated fats, cholesterol, omega-6 and omega-3 were within the recommended amounts. The intake of all fat types (except trans-fat) was not associated with the risk of developing CVD. Trans-fat intake in the second and third quartile increased the risk of CVD by OR 1.86 (95 % CI: 1.03-3.34) and 2.01 (95 % CI: 1.12-3.60), respectively. CONCLUSIONS: while trans-fats may be significantly associated with the development of CVD in the first two quartiles, no association has been detected with other fat types

INTRODUCCIÓN: se ha establecido que la grasa en la dieta es uno de los factores de riesgo significativos en el desarrollo de enfermedades cardiovasculares (ECV). OBJETIVO: este estudio tuvo como objetivo evaluar la posible asociación entre la ingesta de grasa y la ECV. MÉTODOS: el presente estudio de casos y controles se realizó en el centro de la angiografía coronaria. Se inscribieron 399 pacientes que fueron remitidos para una angiografía coronaria electiva con sospecha clínica de enfermedad coronaria. Los datos dietéticos se obtuvieron de cada paciente mediante un cuestionario de frecuencia de alimentos basado en entrevistas. RESULTADOS: los hallazgos del presente estudio no revelaron diferencias significativas entre los casos y los controles con respecto a la ingesta de todos los tipos de grasa, ya sea antes o después del ajuste de energía. Para ambos casos y controles, el porcentaje de ingesta de grasas de la energía total y las ingestas de grasas poliinsaturadas y monoinsaturadas, colesterol, omega-6 y omega-3 se encuentran dentro de las cantidades recomendadas. La ingesta de todos los tipos de grasa (excepto las grasas trans) no se asoció con el riesgo de desarrollar ECV. La ingesta de grasas trans en el segundo y tercer cuartil aumentó el riesgo de ECV en OR 1,86 (IC 95 %: 1,03-3,34) y 2,01 (IC 95 %: 1,12-3,60), respectivamente. CONCLUSIONES: si bien las grasas trans pueden estar asociadas significativamente con el desarrollo de ECV en los dos primeros cuartiles, no se ha detectado asociación con otros tipos de grasa

Adequacy of Nutrients Intake among Jordanian Pregnant Women in Comparison to Dietary Reference Intakes.

OBJECTIVE: Maternal nutrition is considered an important pillar in the pregnancy outcomes for both mother and infant. A mother's malnutrition and inadequate nutrient intake is associated with many undesirable pregnancy outcomes. Hence, assessing the nutritional status of the mother in the early stages of the pregnancy and preventing any inadequacy can preclude many health problems for both mother and infant. Therefore, this study aimed to assess the adequacy of nutrient intakes among Jordanian pregnant women as compared to their corresponding dietary reference intakes (DRIs). METHODS: This cross-sectional study was conducted at a major University Hospital in Jordan. Three hundred pregnant women were invited to participate in the study and 286 agreed to participate. Fifty pregnant women were enrolled at week 9, then 96 pregnant women were at week 20 and 137 pregnant women were at week 30 of pregnancy. The participants completed the interview-based demographic questionnaire, pregnancy physical activity questionnaire, and quantitative food frequency questionnaire (FFQ). RESULTS: The mean energy intake was 2768.9 ± 767.8 kcal/day and it was significantly higher in the 3rd trimester (p < 0.05). Women in the 3rd trimester consumed significantly more protein, carbohydrates, and sugar than women in the 1st and 2nd trimesters (p < 0.05). The pregnant women in the 3rd trimester consumed more sodium than women in the 1st and 2nd trimesters (p < 0.05). The vitamin K intake was significantly (p = 0.045) lower in the 2nd trimester than the 1st and 3rd trimesters. The calcium intake was significantly higher in the 3rd trimester than the 1st and 2nd trimesters (p = 0.021). The total micronutrient (vitamins B1, B2, B3, B6, B12, and D, calcium, and iron) intakes derived from dietary supplements and food sources throughout the 3 trimesters was significantly higher in the 3rd trimester than the 1st and 2nd trimesters (p < 0.05). The vitamin D, calcium, and iron intakes had the most significant increases between the 1st and 3rd trimesters (p < 0.001), while folic acid intake was significantly higher in the 1st trimester than the 2nd and 3rd trimester (p < 0.001). Most women exceeded the tolerable upper intake level (UL) for sodium in all trimesters, while 82% of women exceeded the UL of folic acid in the 1st trimester and from the supplement, not the diet. CONCLUSION: While the intake of some nutrients from food alone remains below the DRIs in the diets of pregnant women, the intake of other nutrients is above the UL. Raising the awareness of pregnant women about their diet and how a supplement intake can reduce the risk of inadequate intake for many micronutrients and improve their pregnancy outcomes is of great importance.
