Objective: several dietary and non-dietary factors and genetic predisposition may play an important role in gastric carcinogenesis. The findingsabout associations between micronutrients and gastric cancer (GC) is still inconsistent. This study aimed to investigate the effect of dietarymicronutrients on gastric cancer risk.Methods: a case-control study comprised of 173 GC (107 males: 66 females) patients and 313 (190 males: 123 females) population-basedcontrols matched for age, occupation, and marital status. Demographics, medical history, physical activity, and nutrient intake information werecollected using reliable interview-based questionnaires. Information on dietary micronutrient intake was collected from the participants using avalidated food frequency questionnaire (FFQ). Multinomial logistic regression was used to calculate Odds ratios (ORs) and their corresponding95 % confidence intervals (CIs) and evaluate associations between dietary micronutrients and GC risk.Results: GC was inversely associated with the consumption of vitamin A, beta-carotene, vitamins D, E, K, B2, B3, B6, B12, and C, folate, chromium,iodine, and selenium.

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.

Food Group Intake of Pregnant Jordanian Women Based on the Three Pregnancy Trimesters.

Inadequate diets have adverse effects on maternal, fetal, and, possibly, childhood health. This cross-sectional study aimed to examine daily food group intake of pregnant Jordanian women during the three pregnancy trimesters and to compare these to the recommended servings of the five food groups reported by The United States Department of Agriculture and My Plate Plan. A total of 283 pregnant Jordanian women were recruited during their antenatal visits. Data were obtained by interviewer-administered structured questionnaires. Our results showed that 1.1% of participants consumed the recommended number of servings for all five food groups during pregnancy and 10.2% did not consume the minimum number of servings of the five food groups. Nearly half of the participants in the first trimester met the recommended daily servings for three food groups but only approximately two-third of participants met the minimum recommended daily servings for one or two food groups in the second and third trimesters. Consumption of grains and sweets was significantly higher in the third trimester compared with the first and second trimesters. Overall, the majority of pregnant Jordanian women in this study did not consume the recommended number of servings for all five food groups during pregnancy.

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.
