“…Postmenopausal breast cancer accounted for about 40% of all cancer cases attributable to excess body mass index across the MENA region in 2012 (44). Other potential risk factors in lifestyle including higher fat intake, smoking and low physical activity (especially in post-menopausal women) could be influential in the increased incidence of breast cancer among Iranian women (45)(46)(47). Furthermore, altered cultural habits of childbearing such as late age of first pregnancy, nulliparity and using formula milk instead of breastfeeding can also be influential (48)(49)(50).…”

National and Subnational Incidence, Mortality, and Years of Life Lost Due to Breast Cancer in Iran: Trends and Age-Period-Cohort Analysis Since 1990

Breast cancer is the most common cancer among women, causing considerable burden and mortality. Demographic and lifestyle transitions in low and low-middle income countries have given rise to its increased incidence. The successful management of cancer relies on evidence-based policies taking into account national epidemiologic settings. We aimed to report the national and subnational trends of breast cancer incidence, mortality, years of life lost (YLL) and mortality to incidence ratio (MIR) since 1990. As part of the National and Subnational Burden of Diseases project, we estimated incidence, mortality and YLL of breast cancer by sex, age, province, and year using a two-stage spatio-temporal model, based on the primary dataset of national cancer and death registry. MIR was calculated as a quality of care indicator. Age-period-cohort analysis was used to distinguish the effects of these three collinear factors. A significant threefold increase in age-specific incidence at national and subnational levels along with a twofold extension of provincial disparity was observed. Although mortality has slightly decreased since 2000, a positive mortality annual percent change was detected in patients aged 25–34 years, leading to raised YLLs. A significant declining pattern of MIR and lower provincial MIR disparity was observed. We observed a secular increase of breast cancer incidence. Further evaluation of risk factors and developing national screening policies is recommended. A descending pattern of mortality, YLL and MIR at national and subnational levels reflects improved quality of care, even though mortality among younger age groups should be specifically addressed.

“…However, several case-control studies and randomized controlled trials have shown that the higher the adherence levels, the lower the BC incidence levels; indeed, poor diet, together with a sedentary lifestyle (e.g. physical inactivity), can increase the risk of developing BC both in Mediterranean Basin countries [45,46,47] and in countries displaying a tendency for “westernization in diet” [48,49].…”

Breast cancer (BC) is the second most common cancer worldwide and the most commonly occurring malignancy in women. There is growing evidence that lifestyle factors, including diet, body weight and physical activity, may be associated with higher BC risk. However, the effect of dietary factors on BC recurrence and mortality is not clearly understood. Here, we provide an overview of the current evidence obtained from the PubMed databases in the last decade, assessing dietary patterns, as well as the consumption of specific food-stuffs/food-nutrients, in relation to BC incidence, recurrence and survival. Data from the published literature suggest that a healthy dietary pattern characterized by high intake of unrefined cereals, vegetables, fruit, nuts and olive oil, and a moderate/low consumption of saturated fatty acids and red meat, might improve overall survival after diagnosis of BC. BC patients undergoing chemotherapy and/or radiotherapy experience a variety of symptoms that worsen patient quality of life. Studies investigating nutritional interventions during BC treatment have shown that nutritional counselling and supplementation with some dietary constituents, such as EPA and/or DHA, might be useful in limiting drug-induced side effects, as well as in enhancing therapeutic efficacy. Therefore, nutritional intervention in BC patients may be considered an integral part of the multimodal therapeutic approach. However, further research utilizing dietary interventions in large clinical trials is required to definitively establish effective interventions in these patients, to improve long-term survival and quality of life.

“…Over the past few decades, epidemiological studies have suggested that physical inactivity or sedentary behaviour (SB) were risk factors for non-communicable diseases, such as breast cancer,1 prostate cancer,2 cardiovascular diseases,3 stroke,4 type 2 diabetes mellitus5 and metabolic syndrome 6. Moreover, a study ranging from the eastern Mediterranean to the western Pacific region showed that more than 5.3 million deaths could be avoided each year, if inactive people became active 7.…”

ObjectivesTo estimate the prevalence and influencing factors of physical activity (PA) and sedentary behaviour (SB) in rural areas of China.DesignCross-sectional study.SettingA multistage, stratified cluster sampling method was used to obtain samples in the general population of Henan province in China.Participants38 515 participants aged 18–79 years were enrolled from the Henan Rural Cohort Study for the cross-sectional study.Main outcome measuresThe International Physical Activity Questionnaire was used to assess the levels of PA and SB. Multiple logistic regression analysis was used to calculate ORs and 95% CIs of potential influencing factors with physical inactivity.ResultsThe age-standardised prevalence of light PA and sitting >7.5 hours per day were 32.74% and 26.88% in the general Chinese rural adults, respectively. Gender differences were: 34.91%, 29.76% for men and 31.75%, 25.16% for women, respectively. The prevalence of participants with both light PA and sitting >7.5 hours per day was 13.95%. Education at least junior middle school, divorced/widowed/unmarried, RMB1000> per capita monthly income ≥RMB500, sitting >7.5 hours per day were negatively associated with light PA. For sitting >7.5 hours per day, the negative factors were being men, divorced/widowed/unmarried, heavy smoking, Fishery products, vegetable and fruits intake .ConclusionPhysical inactivity and SB were high in rural China. There is an increased need to promote a healthy lifestyle to the rural population.Clinical trial registrationThe Henan Rural Cohort Study has been registered with the Chinese Clinical Trial Register.Registration number: ChiCTR-OOC-15006699.http://www.chictr.org.cn/showproj.aspx?proj=11375
