RESUMO

There are few studies that evaluated the relationship between dietary diversity score (DDS) and risk of cancer. The purpose of this study was to examine the association of DDS with the risk of prostate cancer (PC) among Iranian men. This case-control study was performed among 60 cases with prostate cancer and 60 hospital-based controls. Anthropometric measurements were done and demographic information was recorded using standard protocols. A validated 160-item semi-quantitative food frequency questionnaire (FFQ) was used to assess usual dietary intakes. Also, Binary logistic regression was performed to estimate the risk of PC in relation to DDS. After controlling for several confounders (age, body mass index, physical activity, energy intake, job, education, and antihypertensive drugs usage) higher adherence to DDS (OR = 0.33; 95% CI (0.11-0.97)), fruits group (OR = 0.19; 95% CI (0.06-0.63)), and vegetables group (OR = 0.17; 95% CI (0.05 - 0.58)) were significantly associated with lower risk of PC. In contrast, greater adherence to the meat group (OR = 3.88; 95% CI (1.32-11.42)) was significantly associated with increased PC risk. Our results showed that adherence to a diet with higher DDS, especially higher amounts of fruits and vegetables and a lower amount of meat could decrease the risk of PC.

RESUMO

BACKGROUND: Dyslipidemia has been reportedly associated with an increased risk of atherosclerosis among psoriatic patients. Dietary intake can be a key factor in the pathophysiology of psoriasis. Herein, we assessed serum lipid profile and dietary intake in psoriatic patients, in comparison with healthy subjects. METHODS: In this case-control study, 45 psoriatic patients and 43 healthy controls were evaluated. We estimated the macro/micronutrient intakes and energy, using a food frequency questionnaire (FFQ). Anthropometric parameters and serum levels of triglyceride (TG), high-density lipoproteins (HDL), low-density lipoproteins (LDL), and very low-density lipoproteins were assessed. The case group was categorized by severity measured by PASI score (mild<10, moderate 10-20, severe >20). Diet plan 6.0 was used to analyze FFQs and data were analyzed in SPSS 16.0, with p<0.05 considered significant. RESULTS: The case group had markedly higher body mass index (BMI), LDL, and cholesterol and significantly lower HDL compared with controls (p<0.05). Carbohydrate, energy, fat intakes were significantly higher in cases, while folate, fiber, and vitamin E intakes were significantly lower in the case group, compared with the control group (p<0.05). BMI, cholesterol, and triglyceride values and dietary intakes of fiber and vitamin E were significantly associated with severity of psoriasis (p<0.05). CONCLUSION: Serum lipid profile and dietary intake are substantially important in psoriasis severity. Therefore, close monitoring of lipid profile and BMI during admission and follow-up and dietary modification can improve the severity of psoriasis.

RESUMO

OBJECTIVE: Some observational studies investigated the association between dietary energy density (DED) and risk of cancers with inconstant results. In addition, there is no study on such association among patients with prostate cancer (PC). The present study was performed to evaluate the association between dietary energy density (DED) and PC risk. METHODS: In this case-control study, one hundred and twenty-five participants were enrolled (62 cases and 63 controls). Dietary intakes were assessed using 160-item semi-quantitative food frequency questionnaire. In addition, demographic characteristics were collected using a general questionnaire and anthropometric indices were measured based on the available guidelines. The association between DED and PC risk was evaluated using multivariable logistic regression. RESULTS: The results showed that higher DED score was associated with increased risk of PC (OR = 2.59; 95% CI= (1.24-5.40)). Interestingly, after adjusting for potential confounders ((smoking, physical activity, energy intake, education, ethnicity, job, anti-hyperlipidemic drugs, antihypertensive drugs, and aspirin) the results remained significant (OR = 2.87; 95% CI= (1.17-7.05)). CONCLUSION: Our findings suggest that DED may increase the risk of PC. However, more prospective studies are warranted to confirm these results.

RESUMO

This cross-sectional study examined the relationship between maternal pre-pregnancy body mass index (BMI) and dietary intake on birth size in the north-east part of Iran. Maternal information including BMI and dietary intake from 453 healthy pregnant women were collected in 2013-2014. Maternal pre-pregnancy BMI were obtained from health records and dietary intakes in third trimester were collected by using a validated food frequency questionnaire (FFQ), which consisted of 160 Iranian foods. Anthropometric measurements of neonates including weight, height, and head circumference were 3.19 ± 0.49 kg, 50.24 ± 2.1 cm, and 34.61 ± 1.5 cm, respectively. A significant difference was found in neonatal birth weight (p < 0.001) and head circumference (p = 0.002) between underweight and obese mothers. Furthermore, maternal intake of fat had a direct correlation with birth size. There was a positive relationship between vitamin A and potassium intake and birth height. The article concludes that normal maternal pre-pregnancy weight and appropriate diet are likely essential for healthy babies.

RESUMO

BACKGROUND AND AIM: Prostate cancer is the most common cancer among men. Several studies have investigated the effects of dietary patterns on prostate cancer risk, but this topic is still a matter of debate. This study aimed to examine the association between dietary patterns and prostate cancer risk. METHODS: In a case-control study, 60 newly diagnosed prostate cancer cases and 60 hospital-based controls were selected from two main hospitals of Shiraz, Iran. Data on dietary intakes, anthropometric features, and demographic characteristics were collected. To determine the dietary patterns factor analysis, and to estimate the odds ratios (ORs), multivariable logistic regression was performed. RESULTS: Two major dietary patterns were identified: Western dietary (WD) pattern and Mediterranean dietary (MD) pattern. After adjusting for potential confounders, men who had higher scores for WD pattern (above the median) were more likely to have prostate cancer (OR = 5.15; 95% CI (1.44-18.47); P = 0.01) compared with men who had lower scores. A nonsignificant inverse association was found for MD pattern (OR = 0.62; 95% CI (0.22-1.77); P = 0.37). CONCLUSIONS: Our findings suggest that WD pattern may increase the risk of prostate cancer and the beneficial effects of MD pattern on prostate cancer risk need further research.
