    Abstract: Co-existence of iron deficiency and obesity in adults has been reported in many countries. However, little is known on the association between obesity and iron deficiency in Qatar. This study aimed to investigate the link between abdominal obesity indices and iron status among adults in Qatar. A random sample of 1000 healthy Qatari adults, aged 20–50 years, was obtained from Qatar Biobank study. Body weight, waist circumference, dual x-ray absorptiometry (DXA) parameters and iron status indicators were measured using standard techniques. Multiple regression analysis was used to examine the associations. The prevalence of iron deficiency and anaemia were 35.4 and 25%, respectively. Of the participants with a large waist circumference, 31.7% had anaemia. Ferritin significantly increased with the increase in the android fat to gynoid fat ratio and visceral fat in both genders. Serum iron and transferring saturation decreased significantly with the increase in waist circumference in women. In both genders, C-reactive protein increased with the increase in all obesity indices. Standardized values of waist circumference, android fat, gynoid fat ratio and visceral fat were significantly associated with log transformed ferritin in men and women. Waist circumference was inversely related to serum iron (β:-0.95, 95% CI:-1.50,-0.39) and transferrin saturation (β:-1.45, 95%CI:-2.46, -0.43) in women. In men, waist circumference was positively associated with haemoglobin level (β: 0.16, 95% CI:0.04, 0.29). Central obesity coexists with anaemia among the study population. Elevated central obesity indices were associated with an increase in ferritin concentration. The increased ferritin concentration may be attributed to the increase in inflammatory status as a result of an increase in c-reactive protein concentration associated with central obesity.

    Abstract: Background: Poor glycemic control is associated with chronic life-threatening complications. Several studies have revealed that sleep status is associated with glycemic control. Aim: to examine the association between sleep duration, quality and glycemic control among adults with diabetes. Methods: Data on 2500 participants aged 18–60 years were collected from the Qatar Biobank (QBB). Sleep duration and quality were assessed by a self-completed health and lifestyle questionnaire, and glycemic control was assessed using HbA1c. Logistic regression was used to assess the association between sleep duration, napping, snoring and poor glycemic control. Results: After adjusting for age and gender, sleep duration was not associated with poor glycemic control. Lack of association persisted after controlling for smoking, physical activity, education, BMI, fruit and vegetable intake, insulin and medication use. However, sleeping for long hours at night (≥8 h) had a trend in increasing the risk of poor glycemic control (OR = 1.28; 95% CI: 0.94–1.74). Napping was positively associated with poor glycemic control. After adjusting for age and gender, patients who reported “sometimes, frequently, or always” napping had more than 30% increased risk of poor control as compared to patients who reported “never/rarely” napping. Snoring was not associated with poor glycemic control among the study sample when adjusted for age and gender (p = 0.61). Other factors were found to be associated with a better glycemic control such as female, high educational and high physical activity level. Conclusions: our results suggest that napping may be an independent risk factor for a poor glycemic control in diabetes; further investigations are required.

    Abstract: This study aimed at developing a valid culture-sensitive quantitative food frequency questionnaire (FFQ) for Qatari adults. A convenient sample of healthy Qataris (n = 107) were recruited from family members of Qatar University students. The Diet History Questionnaire II of the US National Cancer Institute was translated to Arabic language, back-translated to English, pilot tested, and then modified accordingly to be used in Qatari setting. Participants were asked to complete the translated version of the FFQ. This FFQ was then validated against three 24 h diet recall (24 hDR) including a weekend day. Participants were asked to complete the FFQ again after one-month period to measure its repeatability. Dietary data were analyzed using the dietary analysis software ESHA. The validity and reliability of FFQ were assessed by comparing the median intake of nutrients and foods and by calculating the Pearson correlation coefficients. The median nutrient intakes assessed by the second FFQ were higher than that reported in the baseline FFQ1 except for fat. The percentage of increase varies between 1.5% and 96%. Results of the second FFQ indicated an overestimation of intake for most nutrients (macro and micro). Macronutrient intakes assessed by the two FFQ and 24 hDR were strongly correlated. The correlation coefficients for micronutrient intakes between FFQ2 and 24hDR were lower than that of the two FFQs except for calcium (r = 0.55) and sodium (r = 0.643). They ranged from (−0.17) for fluorine to (0.643) for sodium. The agreement rates for classifying macronutrient intakes into same or adjacent quartile were between 79.4% and 100% for the two FFQs and between 71% and 100% for the second FFQ and 24hDR. The reported consumption of food groups estimated by FFQ2 was significantly higher than that reported by FFQ1. In conclusion, the developed FFQ was sufficiently valid to assess energy and macronutrients but not micronutrients. The reliability was adequate for most nutrients.

    Abstract: Prevalence of vitamin D insufficiency among young Qatari women is ∼85%. The purpose of the study was to develop a food frequency questionnaire (FFQ) and to assess the degree of agreement between food vitamin D intakes derived from FFQ and 24-h food recall (24HFR) in young Qatari women. Design/methodology/approach A vitamin D-centric, 40-item FFQ was developed based on foods consumed in Qatar. In total, 36 Qatari women provided food intakes using FFQ and 24HFR. Vitamin D contents of foods reported in FFQ and 24HFR were computed. Spearman rank correlation was used to evaluate the relation between vitamin D intakes of FFQ and 24HFR. Bland–Altman (BA) plot and quartile comparisons were performed to determine the degree of agreement between food intakes of FFQ and 24HFR. Findings Median intakes of vitamin D from FFQ were significantly higher compared to the vitamin D content from 24HFR (213 IU vs 126 IU; p   〈  0.008). Vitamin D intakes were lower with 24HFR when compared with the intakes of FFQ. There was no significant relationship between food vitamin D intake from FFQ and 24HFR (Spearman rho = 0.16; p   〈  0.35). In cross classification, ∼64% were assigned to the same or adjacent quartiles. As per BA plot, more than 95% food intakes were within the limits of agreement (LOA) (BA index, 2.8%). Originality/value There was a moderate agreement between vitamin D intakes and FFQ and 24HFR. 24HFR should be used with caution in assessing the habitual food vitamin D intake because of limited sources of the vitamer in Qatari cuisine. The FFQ is suitable for estimating the food vitamin D intake in young Qatari women.

    Abstract: To assess the association between dietary patterns and glycaemic control among Qatari adults with type 2 diabetes (T2DM). Design: Cross-sectional analysis using data from the Qatar Biobank Study. Poor glycaemic control was defined as HbA1c ≥7·0 %. Dietary patterns were constructed using factor analysis based on habitual food intake assessed by a FFQ. Medication use was based on self-report. Multivariable logistic regression was used to assess the association. Setting: Qatar. Participants: Adults aged ≥18 years ( n 1000) with known diabetes. Result: The mean age of the participants was 52·3 ( sd 11·5) years. Overall, the prevalence of poor glycaemic control was 57·6 %, and 27·7 % of the participants were insulin users. Three dietary patterns were identified. The modern dietary pattern (high intake of fast food, croissants, white bread and cheese) was inversely associated with poor glycaemic control. The sd increments of the modern pattern had OR for poor glycaemic control of 0·86 (95 % CI 0·68, 1·08) in men and 0·76 (95 % CI 0·61, 0·95) in women. There was a significant interaction between the modern pattern and diabetes medication in men but not in women. In men without diabetes medication, the modern pattern was positively associated with poor glycaemic control with an OR of 2·35 (95 % CI 1·13, 4·87). Conclusions: Male diabetes patients took medication to control diabetes but ate more unhealthy food. In men who were not taking diabetes medication, modern dietary pattern was associated with poor glycaemic control. Promoting healthy eating should be encouraged especially among those under diabetes medication.

    Visceral adiposity index is a better predictor of type 2 diabetes than body mass index in Qatari population
    Ovid Technologies (Wolters Kluwer Health) ; 2020

    Abstract: The prevalence of type 2 diabetes (T2D) has increased recently in Qatar. Body mass index (BMI) is a predictor of T2D in many populations. However, BMI is based on height and weight measurements and not on body adiposity. Therefore, the utility of BMI for predicting the risk of T2D has been questioned. Visceral adiposity appears to be a better predictor of T2D. This study aimed to assess the relative effectiveness of visceral adiposity index (VAI) and body adiposity index (BAI), in comparison with BMI, for T2D among Qatari adults. A random sample of 1103 adult Qatari nationals and long term residents over 20 years old were included in this study. This data were obtained from the Qatar Biobank (QBB). We performed a multivariate logistic regression to examine the association between VAI, BAI, BMI, and T2D, and computed z-scores for VAI, BAI and BMI. VAI z-scores showed the strongest association with the risk of T2D (OR, 1.44; 95% CI: 1.24–1.68) compared with the z-scores for BAI (OR, 1.15; 95% CI: 0.93–1.43) and BMI (OR, 1.33; 95% CI: 1.11–1.59). ROC curve analysis showed that VAI was a stronger predictor than BAI and BMI ( P   〈  .0001). Subgroup analysis indicated that the association was stronger between VAI and T2D in Qatari women than in men. VAI was a stronger and an independent predictor of T2D compared to BAI and BMI among the Qatari adult population. Therefore, VAI could be a useful tool for predicting the risk of T2D among Qatari adults.

    Abstract: Poor glycaemic control is associated with chronic life-threatening complications. This cross-sectional study examined whether there is an association between handgrip strength and glycaemic control among patients with diabetes. Data on 1058 participants aged 40 and older were collected from the National Health and Nutritional Examination Survey (NHANES). Muscle strength was assessed using a handgrip dynamometer, and glycaemic control was assessed using HbA1c. Handgrip strength was presented as age- and gender-specific quartiles, with participants in quartile 1 having the lowest handgrip strength and participants in quartile 4 having the highest handgrip strength. Logistic regression analyses were used to assess the association between handgrip strength and poor glycaemic control among participants with diabetes. Three models, each adjusted to include different variables, were employed. Odds ratio (OR) values revealed no association between handgrip strength and glycaemic control after adjusting for age, gender, and race in model 1. With further adjustment for sedentary activity, income-to-poverty ratio, education, and smoking, patients in quartile 4 of handgrip strength had 0.51 odds of poor glycaemic control (95% CI: 0.27–0.99). However, the reported association above vanished when further adjusted for insulin use (OR = 0.67; 95% CI: 0.35–1.28). In conclusion, findings may indicate an association between glycaemic control and muscle strength. This association may be altered by insulin use; further investigations are required.
