Habitual food consumption, eating behavior and meal-timing among Jordanian adults with elevated Blood pressure: a cross-sectional population-based study.

BACKGROUND: The prevalence of elevated blood pressure (BP) has been raised worldwide. Food consumption, eating habits, and nutritional lifestyle related to meal timing, skipping meals, and meal contents have recently received more attention in studies on BP and metabolic syndrome. Purpose: This study evaluated the association between habitual food consumption, eating behavior, and meal timing with BP among Jordanian adults. METHODS: A cross-sectional study included 771 Jordanian adults. A food frequency questionnaire was completed. Data about eating habits, meal timing, and emotional eating were collected. BP was measured. RESULTS: The prevalence of less than recommended intake of vegetables, milk, protein, and fruits was higher in participants with elevated BP (69.2%, 90.2%, 58.9%, and 25.5%, respectively) as compared to the normal BP group (p < 0.001). Consuming vegetables and milk less than the recommended was reported to significantly increase the likelihood of elevated BP by OR= (1.60, and 2.75 (95%CI: 1.06-2.40; 1.62-4.66). Hence, consuming more than recommended fruit reduced the risk of elevated BP by OR = 0.56 (95%CI: 0.38-0.82). A 63.2% of elevated BP participants have three meals daily, a higher percentage of intake of one (23.5%) and two (45.7%) snacks. However, they had a higher percentage of morning eaters (50.7%), had lunch between 1:00-6:00 PM (92.7%), and had dinner between 6:00 and 9:00 PM (68.1%). CONCLUSIONS: Although Jordanian adults with elevated BP appear to have healthy eating habits and meal timing and frequency, their habitual food consumption falls short of the daily recommendations for milk, fruits, vegetables, and protein.

Numerous epidemiological studies have revealed a steadily rising prevalence of elevated BP, and one critical independent and modifiable risk factor for this condition is obesity.One global non-communicable diseases (NCD) target adopted by the World Health Assembly in 2013 is to lower the prevalence of raised BP by 25% by 2025 compared with its 2010 level.Lifestyle improvement is a cornerstone of CVD prevention; diet is one of the most effective strategies for attaining BP reduction and control as low-salt diets, dietary approaches to stop hypertension (DASH), a low-salt Mediterranean diet, an energy-restriction diet, vegetarian diet, and alternate-day fasting.Eating habits and nutritional lifestyle related to meal timing, skipping meals, and meal contents have recently received more attention in studies on BP and metabolic syndrome.a relationship between elevated BP and metabolic syndrome, infrequent fruit eating, skipping meals, irregular meal frequency and timing, and obesity has been found among adults.It has been found that earlier meal timing could reduce cardiometabolic disease burden and aid in weight loss; on the other hand, meal frequency was inversely associated with the prevalence of abdominal obesity, elevated BP, and elevated triglycerides. Morning eating was associated with a lower prevalence of metabolic syndrome than no morning eating.

Are There Any Correlations between Vitamin D, Calcium, and Magnesium Intake and Coronary and Obesity Indices?

OBJECTIVE: The association between nutrient intake and obesity and coronary problems has received great attention. So, this study aimed to examine the association between vitamin D, calcium, and magnesium intake and obesity and coronary indices. METHODS: A total of 491 male and female university employees (18-64 years) were randomly included in a cross-sectional study. Blood samples were drawn, and the lipid profile was analyzed. Different anthropometrics were measured. Obesity and coronary indices were calculated based on standard formulas. A 24-h recall was used to measure the average dietary intake of vitamin D, calcium, and magnesium. RESULTS: For the total sample, vitamin D had a significantly weak correlation with the abdominal volume index (AVI) and weight-adjusted waist index (WWI). However, calcium intake had a significant moderate correlation with the AVI and a weak correlation with the conicity index (CI), body roundness index (BRI), body adiposity index (BAI), WWI, lipid accumulation product (LAP), and atherogenic index of plasma (AIP). In males, there was a significant weak correlation between calcium and magnesium intake and the CI, BAI, AVI, WWI, and BRI. Additionally, magnesium intake had a weak correlation with the LAP. In female participants, calcium and magnesium intake had a weak correlation with CI, BAI, AIP, and WWI. Additionally, calcium intake showed a moderate correlation with the AVI and BRI and a weak correlation with the LAP. CONCLUSION: Magnesium intake had the greatest impact on coronary indices. Calcium intake had the greatest impact on obesity indices. Vitamin D intake had minimal effects on obesity and coronary indices.

The Novelty of using Obesity Indices as Blood Pressure Predictors.

AIMS: To study the association between selected obesity indices, systolic blood pressure (SBP), and diastolic blood pressure (DBP). METHODS: A cross-sectional study was conducted on 491 Jordanian adults (19-65 years old). The sociodemographic data, anthropometrics, and blood pressure were measured and recorded. Obesity indices (Conicity Index (CI), Abdominal volume index (AVI), Body Roundness Index (BRI), and Weight-adjusted-waist index (WWI)) were calculated using standard validated formulas. RESULTS: Based on age, the SBP had a significant moderate correlation with BRI and AVI in all age groups. In the age group 20 to 34 years, SBP had a significantly moderate correlation with CI, and DBP had a significantly moderate correlation with BRI and AVI. In the age group of 35 to 44 years, DBP had a significantly moderate correlation with CI, BRI, WWI, and AVI. For the age group of 45 to 65 years, the SBP had a significantly moderate correlation with all the obesity indexes, opposite to DBP. Obesity indices explain 23.6 to 24.1 % of the changeability in SBP, and one unit increase in them, increased SBP ranges from 0.61±0.14 to 19.88±4.45. For DBP, obesity indices explained 15.9% to 16.3% of the variability in DBP, and raising them by one unit led to an increase in the DBP range from 0.27±0.11 to 10.08±4.83. CONCLUSION: All the studied obesity indices impacted SBP and DBP with the highest reported effect for AVI and BRI and a lower impact for WWI. The impact of obesity indices on DBP was affected by age group.

Dietary fat types consumption association with obesity and coronary indices.

This article aims to study the different dietary fat types associated with obesity and coronary indices. A sample of 491 healthy adults was included in a cross-sectional manner. Dietary fats intake, obesity indices (conicity index (CI), body adiposity index (BAI), abdominal volume index (AVI), body roundness index (BRI), and weight-adjusted-waist index (WWI)), and cardiovascular indices (cardiometabolic index (CMI), lipid accumulation product (LAP), and atherogenic index of plasma (AIP)) were calculated and studied. Participants with an acceptable intake of omega-3 had a higher BRI score (1⋅90 ± 0⋅06 v. 1⋅70 ± 0⋅06). Participants with an unacceptable intake of cholesterol had a higher CI (1⋅31 ± 0⋅11 v. 1⋅28 ± 0⋅12; P = 0⋅011), AVI (20⋅24 ± 5⋅8 v. 18⋅33 ± 6⋅0; P < 0⋅001), BRI (2⋅00 ± 1⋅01 v. 1⋅70 ± 1⋅00; P = 0⋅003), WWI (11⋅00 ± 0⋅91 v. 10⋅80 ± 0⋅97; P = 0⋅032), and lower AIP (0⋅46 ± 0⋅33 v. 0⋅53 ± 0⋅33; P = 0⋅024). Total fat, saturated fat (SFA), and polyunsaturated fat (PUFA) intake had a significant moderate correlation with AVI and BRI. The monounsaturated fat (MUFA) intake had a significantly weak correlation with CI, AVI, BRI, WWI, and AIP. Cholesterol and omega-6 had weak correlations with all indices. Similar correlations were seen among male and female participants. The different types of fat intake significantly affected obesity and coronary indices, especially SFA and PUFA, as well as omega-3 and cholesterol. Gender and the dietary type of fat intake have a relationship to influence the indicators of both obesity and coronary indices.

Association between dietary fatty acid patterns and obesity indices in Jordanian adults: A cross-sectional study.

Background: The ratios of fatty acids in different diets and their connection to chronic diseases including obesity and CVD have been researched. The current study set out to detect the dietary fatty acid patterns among Jordanian adults and their relationships with obesity indices. Methods: The data of 1096 adults were extracted from a household food consumption patterns survey study. Food intake was analyzed, and fatty acid patterns were determined. After anthropometric measurements, obesity indices were calculated. Results: Two fatty acid patterns were determined (High fatty acids from Protein and Olive Oil sources pattern, and the low Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) pattern), explaining an overall variance of 41.78% and 24.31%, respectively. A significant difference in obesity scores through fatty acids pattern quartiles was only seen among female participants. Q4 of the "High fatty acids from Protein and Olive Oil sources" pattern had a significantly higher means of body mass index (25.12 ± 0.46; p = 0.015), waist-to-height-ratio (0.51 ± 0.01; p = 0.002), weight-adjusted waist index (10.13 ± 0.09; p = 0.021) and body roundness index (3.61 ± 0.15; p = 0.007) compared to Q1, while Q4 of "Low EPA and DHA" pattern had significantly higher means of waist circumference (WC) (86.28 ± 1.34) and a body shape index (ABSI) (10.12 ± 0.30) in comparison to Q1 (WC = 81.55 ± 1.08 and ABSI = 9.07 ± 0.22; p = 0.025, 0.013; respectively). In females, there was a significant association between the "High fatty acids from Protein and Olive Oil sources" pattern and all the obesity indices. Conclusion: Our results suggest that an increase in the high fatty acids from Protein and Olive Oil sources pattern is associated with a reduction in obesity indices, which is opposite to the low EPA and DHA pattern. This was a sex-specific association.

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.

Do macronutrient intakes affect obesity indices in Jordanian adults?

OBJECTIVE: To determine whether macronutrient intake is associated with novel obesity indices, including the conicity index (CI), body adiposity index (BAI), abdominal volume index (AVI), body roundness index (BRI), and weight-adjusted-waist index (WWI). METHODOLOGY: A cross-sectional survey was conducted with 491 adults (344 males and 147 females) working at different universities in Jordan (July-December 2019). Daily intake of energy (kcal), carbohydrates (g), protein (g), and fat (g) was obtained using 24-h recalls collected over 2 days. Additionally, obesity indices were calculated. RESULTS: Regardless of sex, energy, and carbohydrate intakes had a moderately significant positive association, whereas protein and fat intakes had a weakly significant association with BAI, AVI, and BRI. CI and WWI showed a weakly significant association with all macronutrients in males, a moderate correlation with energy and carbohydrate intake, and a weak association with fat and protein intake in females. Male participants had significant increases in the CI (T1 = 1.29 ± 0.01 vs. T3 = 1.36 ± 0.01, p = .018), AVI (T1 = 17.96 ± 0.52 vs. T3 = 22.81 ± 0.57, p = .011), and WWI (T1 = 10.72 ± 0.11 vs. T3 = 11.29 ± 0.09, p = .047) indices scores through the carbohydrate intake tertiles. Additionally, there was a significant increase in scores of AVI (T1 = 18.60 ± 0.56 vs. T3 = 21.42 ± 0.46, p = .048) and an almost significant increase in CI (T1 = 1.30 ± 0.01vs. T3 = 1.33 ± 0.01, p = .056) through the tertiles of protein intake. CONCLUSION: Macronutrients were significantly associated with all indices. The effect of macronutrients on obesity indices is sex-based. Among men, CI, AVI, and WWI were the indices most affected by carbohydrate and protein intakes. Future studies should further investigate food sources and macronutrient quality.

Probiotic supplementation induces remission and changes in the immunoglobulins and inflammatory response in active ulcerative colitis patients: A pilot, randomized, double-blind, placebo-controlled study.

BACKGROUND & AIMS: Clinical studies of using probiotics for managing ulcerative colitis (UC) in Jordan are rare. Therefore, we aimed to evaluate the effect of probiotic supplementation on the clinical disease activity and biochemical parameters in patients with mild-to-moderately active UC. METHODS: thirty mild-to-moderate ulcerative colitis patients were included and randomly assigned to participate in a double-blinded randomized study to receive the treatment (3 × 1010 of probiotic capsules [containing nine Lactobacillus and five Bifidobacterium species], or a placebo), and included in the intention-to-treat analysis. Only 24 completed the study and were included in the per-protocol analysis. Both groups were compared in terms of clinical disease activity and biochemical parameters at the beginning and the end of the study. Registered under ClinicalTrials.gov Identifier no. NCT04223479. RESULTS: There was a significant induction of remission in the probiotic group presented by improvement in the partial mayo score (PMS). Probiotic group had significantly lower stool frequency (0.00 ± 0.00 vs. 1.17 ± 1.19), global assessment (0.42 ± 0.51 vs. 1.00 ± 0.74, p = 0.035), and total PMS score (1.33 ± 0.49 vs. 3.42 ± 1.78). In terms of mean and percent of change in post-to pre-treatment values, there was a significant reduction in C-reactive protein, and an increase in hemoglobin, hematocrit, and RBC levels in the probiotic group (p < 0.05). Additionally, there was a significant reduction in the IgA level and an increase in IL-10 levels among the probiotic group compared to the placebo group (p = 0.039). CONCLUSIONS: The use of probiotic therapy had significantly induced remission in UC patients, this was evidenced by the improvement in the Partial Mayo score. Furthermore, probiotic therapy had an appropriate effect on changes in hemoglobin, hematocrit, C-reactive protein, IgA, and IL-10 levels. This study was registered at ClinicalTrials.gov with the number NCT04223479.

The probiotic supplementation role in improving the immune system among people with ulcerative colitis: a narrative review.

OBJECTIVES: The purpose of this paper is to summarize the current evidence on probiotics' uses as an adjuvant for ulcerative colitis (UC) and provide an understanding of the effect of probiotics supplement on the immune system and inflammatory responses among UC patients and subsequent therapeutic benefits. CONTENT: A narrative review of all the relevant published papers known to the author was conducted. SUMMARY: UC is a chronic inflammatory bowel disease (IBD) that results in inflammation and ulceration of the colon and rectum. The primary symptoms of active disease are diarrhea, abdominal pain, and rectal bleeding. About 70% of the human immune system (mucosal-associated lymphoid tissue) originates in the intestine. Probiotics are live microorganisms that help in stabilizing the gut microbiota (nonimmunologic gut defense), restores normal flora, and enhance the humoral immune system. Probiotics especially Bifidobacterium, Saccharomyces boulardii, and lactic acid-producing bacteria have been used as an adjunct therapy for treating UC to ameliorate disease-related symptoms and reduce relapse rate. Probiotics, in general, modulate the immune system through their ability to enhance the mucosal barrier function, or through their interaction with the local immune system to enhance regulatory T cell responses, decrease the pro-inflammatory cytokines such as tumor necrosis factor alpha and interleukin 1 beta and increase anti-inflammatory factor interleukin 10. OUTLOOK: More studies are needed to explore the properties of the various probiotic bacterial strains, their different uses, as well as the dosage of probiotics and duration for treating different disorders. Further clinical investigations on mechanisms of action and how probiotics modulate the immune system may lead to further advances in managing IBD.

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

Subcutaneous and visceral fat volumes measured by MRI and their relationships with nutrient intakes among adults.

BACKGROUND AND OBJECTIVES: Types and amounts of nutrients may influence the volume of subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT). This study targeted to investigate the relationship between SAT and VAT volumes and macro- and micronutrients intake among adults. METHODS AND STUDY DESIGN: Data were collected via a private face-to-face interview, in which diet history was obtained using validated quantitative food frequency questionnaire. The different fat volumes were assessed using magnetic resonance imaging (MRI) scanning. RESULTS: Participants with the lowest VAT volume had the highest intake of saturated fats, monounsaturated fatty acids and omega-3 and omega-6 fatty acids (p<0.05). VAT volume was significantly associated with the highest level of total energy and energy from carbohydrate consumption among participants while significantly associated with the lowest energy intake from fat among participants (p=0.013). There was a significant relationship with the highest consumption of total carbohydrate, soluble fiber, and insoluble fiber and VAT volume (p<0.05). Participants in the highest VAT volume had significantly the highest intake of vitamin A, ß- carotene, and copper. CONCLUSIONS: This study underscores the importance of quantifying depot-specific body fat and highlights the unique responsiveness of various fat depots to dietary intake.

Dietary inflammatory index and odds of coronary artery disease in a case-control study from Jordan.

OBJECTIVE: The aim of this study was to examine the association between inflammatory potential diet as determined by dietary inflammatory index (DII) scores and coronary artery disease (CAD) in a population-based, case-control study of middle-aged Jordanian adults. METHODS: In the present study, 388 patients who were referred for elective coronary angiography at Prince Hamza Hospital, Amman, were enrolled. Of these, 198 were confirmed CAD cases and 190 were CAD-free control participants. DII scores were computed from dietary intake assessed by a food frequency questionnaire. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: CAD cases had significantly higher DII scores, higher body mass index (BMI), higher prevalence of diabetes, lower educational attainment, and lower physical activity than the CAD-free controls. A statistically significant higher risk for CAD was observed in those with DII scores in the highest tertile than in those in the lowest (ORtertile3vs1, 2.10; 95% CI, 1.18-3.66), after adjusting for cardiovascular risk factors. A positive association was found between higher DII and CAD risk when DII score was used as a continuous variable (ORcontinuous, 1.13 per unit increase in DII corresponding to ∼11% of its range in the current study; 95% CI, 1.00-1.32). CONCLUSIONS: The present findings, obtained in this ordanian population, add to the growing literature indicating that a proinflammatory diet is associated with higher risk for developing CAD.

Relative Validity and Reproducibility of a Food Frequency Questionnaire to Assess Food Group Intake in Pregnant Jordanian Women.

BACKGROUND: Research on the relationship between maternal diet and pregnancy outcomes requires valid dietary assessment tools in pregnancy. OBJECTIVE: This study aimed to develop and examine the relative validity and reproducibility of a quantitative food frequency questionnaire (FFQ) to estimate food group intake in a sample of pregnant Jordanian women. DESIGN: In this validation study, food group intake from a culturally sensitive quantitative FFQ was compared with food group intake from three 24-hour dietary recalls. PARTICIPANTS AND SETTING: The validation study was conducted from 2015 to 2017 at the maternity clinics in Jordan University Hospital among 131 healthy singleton pregnant Jordanian women. Of these women, 30 also took part in the reproducibility phase, which involved repeated completion of the FFQ in a time frame of 1 month. Pregnant women who had gestational diabetes, preeclampsia, and chronic diseases were excluded. MAIN OUTCOME MEASURES: Relative validity and reproducibility of a 117-item quantitative FFQ used to estimate usual food intake over a period of 1 month. STATISTICAL ANALYSES PERFORMED: Intraclass correlation coefficients and weighted κ statistics were calculated to test the reproducibility between the two administrations of the FFQ. Pearson correlations were estimated to validate the FFQ against 24-hour dietary recalls. Cross-classification and Bland-Altman plots were used to examine the agreement between the two dietary assessment methods. RESULTS: The intraclass correlation coefficients between the two FFQs ranged from 0.24 for legumes to 0.93 for processed meats. A moderate level of agreement was observed between two FFQs. De-attenuated and energy-adjusted correlations ranged from 0.08 for sweets and sugar to 0.93 for sugary drinks. On average, 50.9% and 45.2% of participants were classified by the FFQ and the 24-hour dietary recalls into the same quartile based on their crude and energy-adjusted food group intake, respectively. Bland-Altman plots showed satisfactory agreement between two methods for most food groups. CONCLUSIONS: The FFQ showed moderate reproducibility and good relative validity for most food groups.

Are Risk Factors for Coronary Artery Disease Different in Persons With and Without Obesity?

BACKGROUND: Although obesity is an independent risk factor for coronary artery disease (CAD), observational studies have found that persons with obesity have a better prognosis in established CAD compared with those with a normal body weight, suggesting that the underlying risk factors might differ between the two groups. In this study, we studied risk factors for CAD in persons with and without obesity in a Middle Eastern setting where obesity is endemic. METHODS: Five hundred and fifty-six patients referred for elective coronary catheterization at Prince Hamza Hospital, Amman were included in a cross-sectional study. Patients with CAD (n = 353; 63.5%) were compared to patients with a normal coronary angiography (n = 203; 36.5%). Associations between CAD and baseline variables were assessed in multivariate logistic regression models. RESULTS: In persons with obesity, male sex [adjusted odds ratio (AOR) = 2.62, 95% confidence interval (CI): 1.37-4.99], increasing age (45-54 years: AOR = 5.00, 95% CI: 2.01-12.48; 55-64 years: AOR = 3.77, 95% CI: 1.39-10.23; ≥65 years: AOR = 13.87, 95% CI: 4.62-41.63), diabetes mellitus (AOR = 2.79, 95% CI: 1.49-5.22), and smoking (AOR = 2.25, 95% CI: 1.12-4.50) were strong and significant predictors of CAD. The same risk factors were identified in persons without obesity, but in addition, waist circumference (per 1 cm increment: AOR = 1.04, 95% CI: 1.01-1.07) was a significant predictor of CAD in this group. CONCLUSIONS: Sex, age, diabetes mellitus, and smoking predicted CAD in all patients. Waist circumference only predicted CAD in persons without obesity, suggesting that normal-weight central obesity might be an important risk factor in this setting.

Elevated fasting blood glucose, but not obesity, is associated with coronary artery disease in patients undergoing elective coronary angiography in a referral hospital in Jordan.

BACKGROUND: Obesity and its metabolic complications are endemic in the Middle East, but the cardiovascular consequences are not well defined in local studies. OBJECTIVE: To assess the association between fasting blood glucose (FBG), obesity and coronary artery disease (CAD) in Jordan. DESIGN: A cross-sectional, hospital-based study. SETTING: A referral hospital in Amman, Jordan. PATIENTS AND METHODS: Patients with complete anthropomorphic data who were referred for elective coronary angiography were included in the analysis. Associations between CAD, FBG and obesity were assessed in multivariate logistic regression models, adjusting for known risk factors. MAIN OUTCOME MEASURE: The presence of CAD. SAMPLE SIZE: 434 subjects. RESULTS: Only those who underwent coronary angiography and had complete anthropometric data were included in the study: 291 (67.1%) had CAD and 143 (32.9%) had a normal coronary angiogram.The mean body mass index, waist circumference and FBG of the study participants was 30.0 kg/m2, 106.0 cm and 8.8 mmol/L, respectively. The mean FBG was significantly higher in patients with CAD compared to those without CAD (9.5 vs. 7.3 mmol/L, P less than .001). Waist circumference was significantly higher in women with CAD compared to women without CAD (111.0 vs. 105.9 cm, P=.036), but no significant difference was observed in men. In a multivariate analysis, FBG was a strong and significant predictor of CAD; however, none of the measures of obesity were significantly associated with CAD. The findings were robust in a sensitivity analysis that excluded patients with known diabetes mellitus. CONCLUSIONS: Elevated FBG, but not obesity, predicted CAD in a Middle Eastern population. Improved prevention, detection and management of type 2 diabetes should be a priority in this setting. LIMITATIONS: The cross-sectional design cannot control for temporal changes in risk factors and/or reverse causation. CONFLICT OF INTEREST: None.

Relationship of serum leptin with some biochemical, anthropometric parameters and abdominal fat volumes as measured by magnetic resonance imaging.

AIMS: To measure the level of leptin in volunteers and correlate it with several anthropometric, biochemical variables and abdominal fat volumes. METHODS: The level of leptin was investigated in 167 disease-free volunteers. Serum levels of IL-6, adiponectin, and resistin, blood lipid profile (cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglyceride (TG) were determined. Waist circumference (WC) was measured using tape and magnetic resonance imaging (MRI) images. RESULTS: All measured anthropometric (BMI, WC measured by tape and MRI) and biochemical variables (adiponectin, resistin, cholesterol, HDL, LDL and TG); and abdominal fats showed a significant (p<0.05) difference between participants with abnormal serum leptin levels and those with normal leptin levels. A higher percentage of participants with abnormal serum leptin were obese males while participants with normal leptin levels were either overweight or normal weight females. A significant (p <0.05) positive correlation was detected between serum leptin concentration and WC, BMI, subcutaneous fat, visceral fat, total abdominal fat, and resistin. A moderate association was found between serum leptin concentration and the inflammatory cytokine IL-6. CONCLUSION: Abnormal serum leptin, was detected in obese male individuals which may be considered as an important indicator for the development of cardiovascular diseases and type 2 diabetes.

Risk factors for coronary artery disease in patients undergoing elective coronary angiography in Jordan.

BACKGROUND: Unhealthy lifestyle factors such as smoking, obesity, inactivity and type 2 diabetes are endemic in the Middle East. The public health consequences might be detrimental; however, local studies on risk factors for coronary artery disease (CAD) are scarce. METHODS: Patients referred for coronary angiography at a tertiary hospital in Amman, Jordan, between January and December 2015, were included in this study. Risk factors for CAD were assessed in a multivariate logistic regression model, and presented as odds ratio (OR) with 95% confidence interval (CI). RESULTS: Among 557 participants, 356 (63.9%) had CAD and 201 (36.1%) had a normal cardiogram. The majority (n = 395, 70.9%) were male, and median age was 55 years (interquartile range 47-64). Two-hundred-and-fifteen (38.6%) individuals reported previous diabetes, and 287 (51.5%) were current or previous smokers. In multivariate analysis, male gender (OR 3.7, 95% CI 2.3-6.0), age (45-54 years: OR 4.8, 95% CI 2.7-8.5; 55-64 years: OR 6.0, 95% CI 3.2-11.4; ≥65 years: OR 15.7, 95% CI 7.8-31.3), previous diabetes (OR 2.6, 95% CI 1.7-4.1) and current/previous smoking (OR 2.1, 95% CI 1.3-3.4) were significant predictors of CAD. CONCLUSIONS: Age, gender, diabetes and smoking were strong and significant risk factors for CAD in Jordan. Public health interventions to reduce the prevalence of smoking and diabetes are urgently needed.

Dietary patterns and colorectal cancer.

BACKGROUND & AIMS: Dietary pattern and lifestyle have been reported to be important risk factors in the development of colorectal cancer (CRC). However, the mechanism of action of dietary factors in CRC disease is unclear. The aim of this study is the examination of several dietary choices and their potential association with the risk of developing CRC. METHODS: Dietary data was collected from 220 subjects who were previously diagnosed with CRC, and 281 control subjects (matched by age, gender, occupation and marital status). The data was collected between January 2010 and December 2012, using interview-based questionnaires. Multivariate logistic regression was used to estimate the relationship between dietary choices and risk of developing colorectal cancer. RESULTS: Factor analysis revealed three major dietary patterns. The first pattern we identified as the "Healthy Pattern", the second was identified as "High Sugar/High Tea Pattern" and the third as "Western Pattern". In the Healthy Pattern group we found a 10.54% variation in food intake, while the intake variation was 11.64% in the Western Pattern. After adjusting for confounding factors, the Western Pattern food choice was found to be significantly associated with an increased risk of developing CRC (OR = 1.88; 95% CI = 1.12-3.16). The results for the Healthy and High-Sugar/High Tea Patterns showed a decrease, but the statistic was not significant for the risk of CRC development. CONCLUSION: The Western Pattern of dietary choice was directly associated with CRC. The association between the dietary food choice in the Healthy and High-Sugar/High Tea Patterns and colorectal cancer needs further study in our Jordanian population.
