The association between periodontal disease and obesity among adults in Jordan.

AIM To determine the relationship between periodontitis and overweight/obesity among Jordanians. MATERIAL AND METHODS A systematic random sample of 340 persons aged between 18 and 70 years was selected from those who accompanied patients during their visit to the outpatient clinics in the medical centre of Jordan University of Science and Technology in north of Jordan. All participants underwent periodontal examination, had anthropometric measurements, and completed the questionnaire. Periodontitis was defined as presence of four or more teeth with one or more sites with probing pocket depth >or=4 mm and clinical attachment loss >or=3 mm. RESULTS Only 14% of normal weight participants had periodontal disease whereas 29.6% of overweight and 51.9% of obese participants had periodontal disease. Periodontitis was more prevalent among subjects with high waist circumference (WC) and among subjects with high waist-to-hip ratio. After adjusting for important variables, only body mass index (BMI)-defined obesity [odds ratio (OR)=2.9, 95% confidence interval (CI): 1.3, 6.1], high WC (OR=2.1, 95%CI: 1.2, 3.7), and high fat per cent (OR=1.8, 95% CI: 1.03, 3.3) remained significantly associated with increased odds of periodontitis. CONCLUSION BMI-defined obesity, high WC, and high fat per cent were significantly associated with increased odds of having periodontitis.

The association between periodontal disease, physical activity and healthy diet among adults in Jordan

BACKGROUND AND OBJECTIVE Physical inactivity and an unhealthy diet have been implicated as risk factors for several chronic diseases that are known to be associated with periodontitis, such as cardiovascular diseases, obesity and diabetes. Studies investigating the relationship between periodontitis and physical activity and diet are limited. Therefore, this study was conducted to determine the relationship between physical activity, healthy eating habits and periodontal health status. MATERIAL AND METHODS A systematic random sample of 340 persons, 18-70 years of age, was selected from persons accompanying their relative patients who attended the outpatient clinics in the medical center of Jordan University of Science and Technology in north of Jordan. Data collected included socio-demographic and clinical characteristics, anthropometric measurements, physical activity level and dietary assessment. RESULTS Individuals who were highly physically active had a significantly lower average plaque index, average gingival index, average clinical attachment loss (CAL) and percentage of sites with CAL ≥ 3 mm compared to individuals with a low level of physical activity and individuals with a moderate level of physical activity. Those who had a poor diet had a significantly higher average number of missing teeth and an average CAL compared with those who had a good diet. In the multivariate analysis, a low level of physical activity and a poor diet (diets with a healthy eating index score of < 50 points) were significantly associated with increased odds of periodontitis. CONCLUSIONS A low physical activity level and a poor diet were significantly associated with increased odds of periodontal disease. Further studies are needed to understand this relationship in greater detail.

Food insecurity is related to glycemic control deterioration in patients with type 2 diabetes

BACKGROUND & AIMS Poor glycemic control has been shown to play a major role in the development and progression of diabetes complications. This cross-sectional study tested the hypothesis that food insecurity may deteriorate glycemic control in patients with type 2 diabetes. The objectives of this study were to assess the prevalence of food insecurity among type 2 diabetics in a major hospital that serves the area of northern Jordan, and to investigate its relation to glycemic control. METHODS A sample of 843 patients diagnosed with type 2 diabetes participated in the study. Socioeconomic and health data were collected by interview-based questionnaire. Weight and height were measured by a trained nutritionist. Dietary assessment was done using food frequency questionnaire. Dietary data were processed using food processor software. Food insecurity was assessed by the short form of the U.S. food security survey module. Glycemic control was assessed by measuring glycosyated hemoglobin (HbA1c). Statistical procedures used to analyze the data were chi-square, and post-hoc analysis of variance. RESULTS About 22% of the tested sample were food secure (FS); 51% were moderately food insecure (MFIS); and 27% were severely food insecure (SFIS). Higher BMI was associated with SFIS patients. After adjusting for age, gender, income, education, and duration of diabetes, body mass index, and caloric consumption; moderate and severe food insecurity were associated with poor glycemic control (p = 0.04). CONCLUSION food insecurity may be associated with glycemic control deterioration in patients with type 2 diabetes.

Validation of a Food Frequency Questionnaire to Assess Macronutrient and Micronutrient Intake among Jordanians

The aim of this study was to examine the validity and reliability of a food frequency questionnaire (FFQ) among a convenience sample of healthy adults in Jordan. A modified version of the questionnaire known as Diet History Questionnaire I, which measures dietary intakes over a 1-year period, was administrated to 101 apparently healthy men and women recruited from three large medical centers in Jordan. Fifty-five participants completed the modified FFQ and three 24-hour recalls. Participants (N=101) completed the FFQ two times separated by a 1-month period. Reliability of the FFQ was assessed using test-retest method. Mean age of participants was 33.4±18.5 years. Energy, carbohydrate, fiber, fat, saturated fat, calcium, and iron had deattenuated correlations of .732, .563, .544, .487, .484, .451, and .459, respectively. The FFQ and 24-hour recalls produced similar agreement percentages ranging between 25.5% and 43.6%. Mean energy-adjusted reliability coefficients ranged from .695 to .943. A Cronbachs α for the total FFQ items of .857 was found. The modified FFQ has reasonable relative validity and reliability for energy, carbohydrate, fiber, fat, saturated fat, calcium, and iron intakes in Jordanian adults over a 1-year period. However, its application may require additional modifications and validation efforts. Future research is warranted to further modify and test the FFQ in a larger and more diverse sample of Jordanians as well as to develop FFQ for the use among other age groups.

The effect of late pregnancy consumption of date fruit on labour and delivery

We set out to investigate the effect of date fruit (Phoenix dactylifera) consumption on labour parameters and delivery outcomes. Between 1 February 2007 and 31 January 2008 at Jordan University of Science and Technology, a prospective study was carried out on 69 women who consumed six date fruits per day for 4 weeks prior to their estimated date of delivery, compared with 45 women who consumed none. There was no significant difference in gestational age, age and parity between the two groups. The women who consumed date fruit had significantly higher mean cervical dilatation upon admission compared with the non-date fruit consumers (3.52 cm vs 2.02 cm, p < 0.0005), and a significantly higher proportion of intact membranes (83% vs 60%, p = 0.007). Spontaneous labour occurred in 96% of those who consumed dates, compared with 79% women in the non-date fruit consumers (p = 0.024). Use of prostin/oxytocin was significantly lower in women who consumed dates (28%), compared with the non-date fruit consumers (47%) (p = 0.036). The mean latent phase of the first stage of labour was shorter in women who consumed date fruit compared with the non-date fruit consumers (510 min vs 906 min, p = 0.044). It is concluded that the consumption of date fruit in the last 4 weeks before labour significantly reduced the need for induction and augmentation of labour, and produced a more favourable, but non-significant, delivery outcome. The results warrant a randomised controlled trial.

Gestational nutrition improves outcomes of vaginal deliveries in Jordan: an epidemiologic screening.

Adequate and balanced nutrition during gestation is essential for achieving healthy pregnancy outcomes. This retrospective survey tested the hypothesis that maternal nutrition (macronutrients intake, micronutrients intake, and weight gain) during gestation will impact gestational outcomes (gestational age, birth weight, and labor spontaneity). The objectives of this study were to test the impact of macronutrients and micronutrients consumed during gestation, pregestational weight and weight gain during gestation on gestational age, birth weight, and labor spontaneity among Jordanian women. Study participants (n = 700) were recruited from a womens hospital in northern Jordan. Data were collected using structured interviews. Dietary determinants examined in the study included daily intake of macronutrients (energy, carbohydrate, protein, fat, and n-3 and n-6 fatty acids) and micronutrients (zinc, calcium, folate, vitamin C, vitamin A, and vitamin B6), pregestational body mass index, total weight gain, and weight gain pattern during pregnancy. Dietary data were obtained from a semiquantitative food frequency questionnaire. Mean (SEM) daily intakes of energy, carbohydrate, and protein were 10894 (138) Kj, 320 (3.8) g, and 90 (0.95) g, respectively; with fat contributing 36% of total energy. Average daily energy and carbohydrate intake during pregnancy were related negatively to gestational age (P < .05). Pregestational body mass index was associated positively with gestational age and birth weight (P < .05). Intakes of vitamin A and calcium had significant relationships with birth weight. Daily intakes of zinc, calcium, vitamin B6, and n-3 and n-6 fatty acids were associated with labor spontaneity. Dietary factors consumed during pregnancy are associated with pregnancy outcomes.

Physical inactivity, water intake and constipation as risk factors for colorectal cancer among adults in Jordan.

BACKGROUND Physical activity has been found to play a role in cancer prevention. The purpose of this matched case-control study was to investigate the association between physical activity levels, water intake, constipation and colorectal cancer (CRC). MATERIALS AND METHODS Two hundred and thirty-two patients diagnosed with CRC (125 male, 107 female) were enrolled in this case-control study. Cases were matched to 271 population controls (137 male, 134 female). RESULTS Drinking more than 4 cups of water daily decreased the risk of CRC by 33-42%; however, this effect was non-significant. Having constipation was found to be a significant risk factor for developing CRC with an OR=6.284 (95%CI=2.741-14.40). With reference to sedentary behavior, minimum activity (600-3000 Metabolic Equivalents Task (MET)) had 43% protection against CRC and the level of Health Enhancing Physical Activity OR was 0.58 (at 95%CI; 0.37-0.92). A significant negative association was found between CRC and physical activity levels expressed as both METs and MET-hours/week (p for trend=0.017 and 0.03, respectively). Among females, a significant trend of reduction in CRC by 62% was observed with increasing the level of physical activity expressed in MET (p for trend=0.04). CONCLUSIONS The risk of CRC may be reduced by adopting a healthy lifestyle and practicing physically activity regularly, especially among females. Consuming adequate amounts of water and healthy bowel motility could also reduce the risk of CRC.

Macro- and Micronutrients Consumption and the Risk for Colorectal Cancer among Jordanians

Objective: Diet and lifestyle have been reported to be important risk factors for the development of colorectal cancer (CRC). However, the association between total energy and nutrient intake and the risk of developing CRC has not been clearly explained. The aim of our study is to examine the relationship between total energy intake and other nutrients and the development of CRC in the Jordanian population. Research Methods and Procedures: Dietary data was collected from 169 subjects who were previously diagnosed with CRC, and 248 control subjects (matched by age, gender, occupation and marital status). These control subjects were healthy and disease free. Data was collected between January 2010 and December 2012, using interview-based questionnaires. Logistic regression was used to evaluate the association between quartiles of total energy, macro- and micronutrient intakes with the risk of developing CRC in our study population. Results: Total energy intake was associated with a higher risk of developing CRC (OR = 2.60 for the highest versus lowest quartile of intake; 95% CI: 1.21–5.56, p-trend = 0.03). Intakes of protein (OR = 3.62, 95% CI: 1.63–8.05, p-trend = 0.002), carbohydrates (OR = 1.41, 95% CI: 0.67–2.99, p-trend = 0.043), and percentage of energy from fat (OR = 2.10, 95% CI: 0.38–11.70, p-trend = 0.009) significantly increased the risk for the development of CRC. Saturated fat, dietary cholesterol and sodium intake showed a significant association with the risk of developing CRC (OR = 5.23, 95% CI: 2.33–11.76; OR = 2.48, 95% CI: 1.18–5.21; and OR = 3.42, 95% CI: 1.59–7.38, respectively), while vitamin E and caffeine intake were indicative of a protective effect against the development of CRC, OR = 0.002 (95% CI: 0.0003–0.011) and 0.023 (95%CI: 0.008–0.067), respectively. Conclusion: Our results suggest an increased risk for the development of CRC in subjects with high dietary intake of energy, protein, saturated fat, cholesterol, and sodium, and diets high in vitamin E and caffeine were suggestive of a protective effect against the risk of developing CRC. Impact: This is the first study in Jordan to suggest that it may be possible to reduce CRC risk by adjusting the intake of some macro-and micronutrients.

Assessment of Nutritional Status Among ESRD Patients in Jordanian Hospitals

OBJECTIVE Our objective was to assess nutritional status and compare quality of treatment among hemodialysis patients in public and private hospitals in Jordan. DESIGN We utilized a cross-sectional survey. SETTING Our setting involved hospital hemodialysis units. PATIENTS This study was undertaken in five large Jordanian hospitals between 2004 and 2005. One hundred and eighty participants diagnosed with end-stage renal failure (ESRD) were enrolled. These participants (91 women and 89 men) who underwent hemodialysis treatment were recruited using a convenience sampling technique. Data from participants who received hemodialysis treatment in public hospital settings were compared with equivalent data from participants treated in private hospital settings. MAIN OUTCOME MEASURES Subjective global assessment (SGA), anthropometry, and biochemical measurements were used as evaluative tools. RESULTS In the anthropometric measurement of triceps skinfold thickness (TSF), we found a statistically significant difference (P < .05) between participants treated in the two hospital settings. In addition, approximately 62% of all participants, regardless of treatment site, were found to be moderately to severely malnourished. Anthropometric measurements showed some significant increase between prehemodialysis and posthemodialysis weight and body mass index in private hospitals; this was not unexpected. There were no statistically significant differences in the measured mean levels of eight different biochemical parameters, with the exception of plasma phosphorus and sodium levels. CONCLUSIONS The prevalence of malnutrition and the quality of treatment in our two groups of participants were similar.

Fruit and Vegetable Intake among Jordanians: Results from a Case-Control Study of Colorectal Cancer:

BACKGROUND Diets that include fruits and vegetables have been suggested as one way to reduce the risk of developing colorectal cancer (CRC); however, the association between consuming fruits and vegetables and CRC risk is not clear. The objective of the present study is to compare fruit and vegetable intake between 2 groups of Jordanians and further investigate this possible relationship. METHODS A history of fruit and vegetable consumption was obtained from 220 people with CRC and 281 healthy controls, all of whom were from Jordan. Both groups were matched for age, sex, occupation, and marital status. Fruit and vegetable consumption was quantified for the previous 12 months in both groups. RESULTS Total vegetable intake was associated with the risk of developing CRC. Consuming 5 servings of vegetables a day decreased the risk of developing CRC when compared with no more than 1 serving a day (odds ratio [OR] = 0.23; 95% confidence interval [CI]: 0.55-0.97). A significant direct relationship between CRC risk and consuming cauliflower and cabbage was found; however, no association was found for raw or cooked leafy vegetable and other vegetable types. Consuming several types of fruits also revealed no association with risk of CRC, although an increased intake of dates and figs was associated with a reduced risk of developing CRC. The ORs for the highest intake of servings compared with the lowest intake were 0.48 (95% CI: 0.27-0.87; P = .004) for dates and 0.604 (95% CI: 0.35-1.06; P = .003) for figs. CONCLUSIONS Consuming fruits and vegetables did not significantly correlate with a lowered incidence of CRC. However, a trend of protection was detected for several types of fruits and vegetables.
