Background Aggression is one of the most prevalent behavioral disorders in men. Objective This study aimed to assess the possible association between dietary intake of food groups and aggression in middle-aged married men. Methods This case-control study included 336 participants (168 men with aggressive behaviors and 168 healthy controls) aged 35–55 years. Demographic information was collected using a socio-demographic questionnaire. A food frequency questionnaire was used to investigate the diet group intake last year. Based on the normality of the data distribution, Independent t-tests and Mann-Whitney tests were used to compare quantitative variables between the two groups. Categorical variables were compared between cases and controls using the Chi-squared test. Logistic regression analysis was used to examine the possible association between food intake and aggression. Results Compared to controls, aggressive men had significantly higher mean weight, height, and waist circumference (WC), p = 0.007, p = 0.001, and p = 0.043, respectively. After adjusting WC, energy intake, and educational level, in Model 1, intake of milk, cheese, poultry, red meat, legumes, egg, fruits, and vegetables had a significant protective role on the occurrence of aggression, (Odd Ratio (OR) = 0.36; 95% (Confidence Interval (CI) = 0.204, 0.670; P = 0.001), (OR = 0.440; 95% CI = 0.284, 0.781; P = 0.005), (OR = 0.621; 95% CI = 0.284, 0.781; P = 0.046), (OR = 0.358; 95% CI = 0.198, 0.647; P = 0.001), (OR = 0.434; 95% CI = 0.243, 0.773; P = 0.005), (OR = 0.411; 95% CI = 0.229, 0.736; P = 0.003), (OR = 0.332; 95% CI = 0.180, 0.614; P < 0.001), (OR = 0.310; 95% CI = 0.168, 0.572; P < 0.001), respectively. Conclusions Lower WC and a diet containing high-quality protein, fruits, and vegetables can have a protective role against aggression and are recommended for men with an aggressive mood. This diet can affect plasma levels of tryptophan and, therefore, brain levels of serotonin.

Background: Depression and obesity are among the increasingly publicized health problems, both being related to critical complications, and increasing the risk of substantial morbidity and mortality. An increasing number of documents indicate that obesity affects mental status, low serum cholesterol levels, and is related to depressive symptoms. The purpose of the present study was to evaluate the possible significant difference in lipid profile levels, body mass index (BMI), waist circumference (WC), and blood pressure (BP), between depressive and nondepressive older adults. Methods: This was a case–control study where 107 patients, over 65-year-old, were enrolled in this study. Serum total cholesterol, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol (LDL-C), triglycerides (TG), BP, and fasting blood sugar were measured. Data were analyzed using the statistical SPSS software version 22. Independent t-test was used to compare the results between the two groups and the Chi-square test was used to compare categorical variables. In addition, nonparametric Mann–Whitney test was used to evaluate the data. Results: The depressive group showed significant lower BMI, WC, LDL-C, and TG (P < 0.001, P < 0.001, P < 0.016, and P < 0.014). Furthermore, the findings showed significantly higher systolic and diastolic BP in participants who had shown depressive symptoms (P < 0.035 and P < 0.024). Conclusions: The findings suggest that a low BMI, serum LDL-C, and TG are related to depressive symptoms the Iranian elderly.

Introduction:Spontaneous abortion or pregnancy loss is defined as the natural death of fetus before 20th weeks of pregnancy. There is a possibility that food intake is related to spontaneous abortion. Therefore, this study was performed with aim to compare body mass index (BMI) and food intake between women with spontaneous abortion and women with successful pregnancy. Methods: This case-control study was performed on 45 women with spontaneous abortion (cases) and 112 women with term and health neonates' birth (controls) who referred to the obstetrics and gynecology hospital of Farideh Behbahani of Behbahan city in 2016. The subjects were answered by Brief food frequency questionnaire about food intakes during recent pregnancy.Weight before pregnancy and height were extracted by referring to health records and BMI was calculated. Data were analyzed by SPSS statistical software (Version 20) and independent-t test or Mann-Whitney and Chi-square test. P<0.05 was considered significant. Results: Women with spontaneous abortion had significantly higher weight and BMI. This group of women had consumed less fruit (p<0.001), green vegetables (p<0.001), milk and cheese (p<0.001) compared to healthy women. Conclusion: High pre-pregnancy BMI and poor diet in terms of fruits, green vegetables and dairy products are associated with spontaneous abortion and probably increase its occurrence.
