Despite increasing evidence for the association of food-based dietary patterns with breast cancer risk, knowledge about the shape of the relationship and the quality of meta-evidence are insufficient. We aimed to summarize the associations between food groups and risks of breast cancer. We performed a systematic literature search of the PubMed and Embase databases up to March 2020. We included cohort, case-cohort, nested case-control studies, and follow-up studies of randomized controlled trials that investigated the relationship between breast cancer risk and at least 1 of the following food groups: red meat, processed meat, fish, poultry, egg, vegetables, fruit, dairy product (overall, milk, yogurt, and cheese), grains/cereals, nuts, legumes, soy, and sugar-sweetened beverages. Summary risk ratios (RRs) and 95% CIs were estimated using a random-effects model for linear and nonlinear relationships. Inverse linear associations were observed for vegetables (RR per 100 g/d, 0.97; 95% CI, 0.95–0.99), fruit (RR per 100 g/d, 0.97; 95% CI, 0.95–0.99), cheese (RR per 30 g/d, 0.95; 95% CI, 0.91–1.00), and soy (RR per 30 g/d, 0.96; 95% CI, 0.94–0.99), while positive associations were observed for red (RR per 100 g/d, 1.10; 95% CI, 1.03–1.18) and processed meat (RR per 50 g/d, 1.18; 95% CI, 1.04–1.33). None of the other food groups were significantly associated with breast cancer risk. A nonlinear association was observed only for milk, such that the intake of >450 g/d increased the risk, while no association was observed for lower intake amounts. High intakes of vegetables, fruit, cheese, and soy products and low intakes of red and processed meat were associated with lower risks of breast cancer. However, causality cannot be inferred from these statistical correlations.

BACKGROUND: Menopause is associated with decreased sexual activity and a feeling of decreased attractiveness and sexual potency. This study tested the hypothesis that sexual health in postmenopausal women is not the same as nonmenopausal women with regard to symptoms of stress, anxiety, and depression. MATERIALS AND METHODS: This cross-sectional study was conducted in 12 health centers in Shiraz between April and September 2015; 310 postmenopausal women included by convenient sampling. Data were collected through the Female Sexual Function Index, and depression anxiety stress scale 21 questionnaires. Analysis performed using SPSS version 22 and included descriptive statistics, Chi-square or Fisher's exact test, and Pearson correlation and linear regression; p < 0.05 was considered statistically significant. RESULTS: The percentage of women with sexual dysfunction in the present study was 88.7%. There was a significant relationship between stress (p = 0.04), anxiety (p = 0.01), and sexual dysfunction. Furthermore, there was a statistically significant relationship between depression (p = 0.003) and sexual dysfunction. Pearson correlation coefficient showed that there was an inverse relationship among stress (−0.24), anxiety (−0.25), depression (−0.30), and sexual function. In addition, linear regression results showed that depression was the most important factor in the description of sexual dysfunction. CONCLUSION: This study showed that there is an association of the status of mental health and sexual function in post-menopausal women. However, more studies should be carried out to find the confounders.

Objective: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among women of reproductive age.PCOS is considered to be not only a reproductive endocrinopathy, but also a metabolic disorder.The objective of the present study was to characterize the anthropometric and dietary profile of women with PCOS and to compare it with that of healthy age-matched women. Design: In this case-control study, 65 women with PCOS served as cases. The control group consisted of 65 age-matched healthy women. For each participant, demographic, anthropometric and dietary intake data were gathered and compared between the two groups. Results: There was no significant difference between the mean of the body mass index of the two groups, but the mean of waist circumference was significantly higher in the PCOS group, than the control group ( P = 0.016). Compared to the normal weight PCOS patients, a significantly higher percentage of overweight patients had hirsutism ( P = 0.009). In dietary analysis, women with PCOS consumed more calories and more fat than healthy women ( P = 0.001 and P = 0.019, respectively). Conclusion: It is concluded that in PCOS patients, android obesity is a common feature and this abdominal adiposity may be related to the syndrome's complications. PCOS symptoms were more severe in overweight patients than the normal weight. Regarding the dietary pattern, it was indicated that patients with PCOS consume more calories and more fat in their diets and this might have been correlated to their disease.

Social media (SM) exerts important effects on health-related behaviors such as eating behaviors (EB). The present study was designed to determine the direct and indirect association of SM addiction with EB in adolescents and young adults through body image (BI). In this cross-sectional study, 12–22 years old adolescents and young adults, with no history of mental disorders or psychiatric medications usage were studied through an online questionnaire shared via SM platforms. Data were gathered about SM addiction, BI, and EB in its sub-scales. A single approach and multi-group path analyses were performed to find possible direct and indirect associations of SM addiction with EB through BI concerns. Overall, 970 subjects, 55.8% boys, were included in the analysis. Both multi-group (β = 0.484, SE = 0.025, P < 0.001) and fully-adjusted (β = 0.460, SE = 0.026, P < 0.001) path analyses showed higher SM addiction is related to disordered BI. Furthermore, the multi-group analysis showed one unit increment in SM addiction score was associated with 0.170 units higher scores for emotional eating (SE = 0.032, P < 0.001), 0.237 for external stimuli (SE = 0.032, P < 0.001), and 0.122 for restrained eating (SE = 0.031, P < 0.001). The present study revealed that SM addiction is associated with EB both directly and also indirectly through deteriorating BI in adolescents and young adults.
