Associations between Preserved foods and Breast Cancer Risk in Hong Kong Chinese Women. Cancer Prev Res (Phila) 2022; 15:497-507. [PMID: 35504011 DOI: 10.1158/1940-6207.capr-21-0509] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Revised: 02/21/2022] [Accepted: 04/29/2022] [Indexed: 11/16/2022]
Abstract
Preserved food such as cured foods may contain nitrate and nitrite that may contribute to the breast cancer development. Evidence on the associations between these preserved food intakes and risk of breast cancer is sparse. This study aimed to examine the associations between preserved foods (i.e. cured meat, pickled vegetables, canned meat, canned fruit/vegetables) and breast cancer risk in Hong Kong Chinese women. A total of 1307 breast cancer cases and 1050 age-matched controls were recruited from three hospitals during 11/2011-01/2018. We used a standardized questionnaire to collect information on dietary factors including preserved foods. Unconditional multiple logistic regression was performed to calculate the adjusted odds ratio(AOR) of breast cancer in relation to preserved food with adjustment of potential confounders. We further performed stratified analysis according to the breast cancer biology subtypes. We found that cured meat consumption was significantly associated with the risk of breast cancer [AOR=1.32, 95% confidence interval 95%CI)=1.06-1.64]. Compared to no cured meat consumption, cured meat intake {greater than or equal to} once per week was associated with an AOR of 2.66 (95%CI=1.38-5.35). Women with canned fruit/vegetable {greater than or equal to} consumption once per week had a higher risk of breast cancer (OR=1.19, 95%CI=1.00-1.41), particularly for the HER2-positive subtypes, but it became borderline after adjustment of confounders. Our study reveals a positive association between consumption of cured meat and breast cancer risk in Chinese population. Cured meat intake might be a potential novel risk factor for breast cancer but this would have to be confirmed by large prospective cohort studies.

Global, Regional, and National Estimates of Nutritional Deficiency Burden among Reproductive Women from 2010 to 2019. Nutrients 2022; 14:nu14040832. [PMID: 35215481 PMCID: PMC8877546 DOI: 10.3390/nu14040832] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 01/30/2022] [Accepted: 02/11/2022] [Indexed: 02/04/2023] Open
Abstract
Women of reproductive age (15–49 years) are often considered a vulnerable population affected by nutritional deficiencies, impairing their health and that of their offspring. We briefly introduced (a) the incidence and disability-adjusted life years (DALYs) trends from 2010 to 2019 and (b) the correlation between sex differences and income levels and nutritional deficiencies of reproductive women firstly. Notably, the burden of overall nutritional deficiencies among reproductive women remained generally stable from 2010 to 2019, whereas the iodine and vitamin A deficiencies as a subcategory were associated with increased incidence rates and DALYs, respectively. A significant increasing trend occurred in South Asia, Southeast Asia, and Turkey for incidence, and Western Sub-Saharan Africa and Zimbabwe had a strong increase for DALYs. Further analysis of the correlation between nutritional deficiency incidence and economic capacity showed that they were not correlated with the income of women themselves, as was the result of income difference with men. The results of this study will help to identify gaps in nutritional deficiency burden among reproductive women and facilitate the development of regional or national responses. Compared with economic capital, macroscopic political guarantees and social and cultural capital are important measures to remedy the nutritional deficiencies of reproductive women.

Abstract
Objective The aim of the present study was to investigate the possibility of the effect of life long stressful events, along with coping method used, perception of social support, and life style on the development of breast cancer. Methods In this hospital-based case control study, the study group comprised 250 women with breast cancer who were followed by Florence Nightingale Breast Study Group. Control group included 250 women, who had similar sociodemographic characteristics to the study group. Data were collected with semi-structured interview form, Healthy Life Style Behavior Scale, Coping Strategy Indicator, and Stress Evaluation Form developed by us. Results In multivariate analysis, family history of cancer (OR: 1.55, 95% CI: 2.29-1.05), inadequate social support (OR: 1.83, 95% CI: 1.23-2.73), and loss of father during childhood (OR: 2.68, 95% CI: 5.52-1.30) and serious stressor within the last five years (OR: 4.72, 95% CI: 7.03-3.18) were found to be risk factors increasing the risk of breast cancer. When family history of cancer was excluded from the model, the presence of psychiatric disorder history (OR: 1.95, 95% CI: 3.26-1.17) and major life events (OR: 2.24, 95% CI: 4.07-1.24) were added to the model as risk factors. Conclusion The present study indicates that especially the stressful events experienced within the last five years plays an undeniable role in the risk of breast cancer. Social support may be as important in the period before the diagnosis as in the period after diagnosis.

Abstract
OBJECTIVE The aim of this study was to determine the roles of biopsychosocial risk factors in the development of breast cancer. MATERIALS AND METHODS This hospital-based case-control study included 491 women with breast cancer (study group) and 512 women who did not have cancer or other serious diseases (control group). Biological, psychological, and social risk factors were compared between the two groups. Data were collected using the semi-structured interview, the Stress Assessment Form, and the Coping Strategy Indicator to assess these factors. RESULTS When the significantly different biopsychosocial variables between the study and the control groups were evaluated together, independent breast cancer risk factors were found as follows: a stressor experienced in the last 5 years, age 40 years and older, inadequate social support perception, use of avoidance coping strategy, being a housewife, having a family history of cancer, and having a body mass index ≥25. CONCLUSION This study showed a relationship between breast cancer risk and manageable variables (obesity, stressor and coping strategy, social support, and employment status), age and family history of cancer, which are biopsychosocial factors. Biopsychosocial aspects are becoming a greater part of many different healthcare systems.

Abstract
PURPOSE Epidemiologic characteristics of breast cancer in Iran are significantly different from those in the West and even other regional countries, but little is known about the related factors. PATIENTS AND METHODS A hospital-based case-control study was conducted on 1052 women (526 new cases and 526 controls). Logistic regression was performed to investigate associations of study factors with breast cancer risk. RESULTS This study introduced occupation (odds ratio [OR]employed/household, 1.77; 95% confidence interval [CI], 1.15-2.69), marital age (OR24-30 y/< 18 y, 2.13; 95% CI, 1.03-4.40), age at first delivery (OR≥ 30 y/< 18 y, 3.53; 95% CI, 1.73-7.18), parity (OR1-2/Nulliparous or never married, 2.61; 95% CI, 1.13-6.02), birth interval (OR30-50 mos/< 18 mos, 2.38; 95% CI, 1.45-3.89), lifetime breastfeeding (OR≥ 42 mos/< 6 mos, 0.37; 95% CI, 0.18-0.77), and menarche age (year) (OR, 0.87; 95% CI, 0.79-0.96) as significant associates of breast cancer. In addition, body mass index (OR, 1.07; 95% CI, 1.02-1.11) and some health-related behaviors including hair coloring on a regular basis (ORyes/no, 1.93; 95% CI, 1.41-2.62), smoking (ORyes/no, 2.02; 95% CI, 1.22-3.34), oral contraceptive usage (ORever/never. 1.46; 95% CI, 1.05-2.04), physical inactivity (ORinactive/regular activity, 1.54; 95% CI, 1.39-1.75), past life stress (ORoften stressful/often calm, 2.40; 95% CI, 1.62-3.56), and regular bedtime (ORoften regular/no, 0.32; 95% CI, 0.19-0.54) were related to a higher risk of breast cancer. CONCLUSION This study revealed a significant number of factors that seem to contribute to the risk of breast cancer even more than the other previously introduced factors.

Abstract
Asia is the world's largest continent comprising about 3/5 of the human population. Breast cancer is the most common type of cancer and the second leading cause of cancer-related deaths among women in Asia, accounting for 39% of all breast cancers diagnosed worldwide. The incidence of breast cancer in Asia varies widely across the continent and is still lower than in Western countries, but the proportional contribution of Asia to the global breast cancer rates is increasing rapidly in parallel to the socioeconomic development. However, the mortality-to-incidence ratios are much higher for Asia than for Western countries. Most Asian countries are low- and middle-income countries (LMICs) where breast cancer presents at a younger age and a later stage, and where patients are more likely to die from the disease than those in Western countries. Moreover, diagnostic workup, treatment and palliative services are inadequate in most Asian LMICs. In this review, we present an overview of the breast cancer risk factors and epidemiology, control measures, and cancer care among Asian countries.

Abstract
Epidemiological studies suggest a possible association between BMI, diagnosis and clinical-pathological breast cancer characteristics but biological bases for this relationship still remain to be ascertained. Several biological mechanisms play a role in the genesis and progression of breast cancer. This study aimed to investigate relationships between BMI and breast cancer diagnosis/progression in a Southern Italian population and to try to interpret results according to the serum proteomic profile of healthy and breast cancer patients. BMI, presence or absence of breast cancer and its clinical-pathological characteristics were analyzed in a series of 300 breast cancer women and compared with those of 300 healthy women prospectively. To investigate whether obesity is associated with alterations in serum protein profile, SELDI-ToF approach was applied.Alcohol consumption (22.7% vs 11.3%; p<0.001) and postmenopausal status (65.7% vs 52%; p<0.001) but not BMI resulted significantly different in patients vs controls. Conversely, BMI was significantly associated with a larger-tumour size (BMI> = 30 respect to normal weight: OR = 2.49, 95% CI 1.25-4.99, p = 0.0098) and a higher probability of having positive axillary lymph node (OR = 3.67, CI 95% 2.16-6.23, p<0.0001). Multivariate analysis confirmed the association of breast cancer diagnosis with alcohol consumption (OR = 2.28;CI 1.36-3.83; p<0.0018). Serum protein profile revealed the presence of significant (p-value <0,01) differentially expressed peaks m/z 6934, m/z 5066 in high BMI breast cancer patients vs healthy subjects and m/z 6934, m/z 3346 in high vs low BMI breast cancer patients.The analysis of pathological features of cancer indicates that normal weight women have a significantly higher probability of having a smaller breast cancer at time of diagnosis and negative axillary lymph nodes while increased BMI is associated with an altered protein profile in breast cancer patients. Further studies to identify specific proteins found in the serum and their role in breast cancerogenesis and progression are in progress.

Abstract
UNLABELLED The aim of this study was to determine the rate of and causes of asking for telephone counseling in patients undergoing modified radical mastectomy (MRM) and breast-conserving surgery (BCS), and discharged one night after surgery. METHOD This is a randomized descriptive study. This study was conducted on surgery service of a university hospital in Istanbul, Turkey, with MRM and BCS patients. This study sample included 174 patients. Inclusion criteria were staying in hospital for one night and being discharged, ability to talk on the phone, and being a candidate for MRM or BCS. Data were collected on a form that was developed by the researcher after consultation with experts, reviewing THE related literature, and clinical observations. The patients were given two mobile telephone (for two of the researchers) and home telephone number (for two of the researchers) that had an answering machine and were encouraged to call or leave a message for health problems they experienced at home. RESULTS A higher rate of the patients undergoing mastectomy asked for telephone counseling. The rate of the women asking for telephone counseling was very high within the first 6 weeks of discharge. The leading causes of asking for telephone counseling were wound problems, arm exercises, and difficulties in adapting to daily living activities. The women also had a psychological problem: fear of inability to recover. CONCLUSIONS The study found that home follow-up of patients undergoing mastectomy was particularly important.

Abstract
The objective of the present review was to examine the potential association between animal fat intake and breast cancer. We conducted a meta-analysis and review of epidemiological cohort studies, including data reported in the Pooling Project publication of Prospective Studies of Diet and Cancer. Random- and fixed-effects models were utilised to generate summary relative risk estimates (SRRE), and sensitivity and influence analyses were conducted. In the meta-analysis that included data reported in the Pooling Project publication of prospective cohorts (n 8) and subsequent publications of cohort studies (n 3), no significant association was observed comparing the highest category of animal fat intake with the lowest (SRRE 1.03; 95 % CI: 0.76, 1.40). Similarly, no significant association between a 5 % increment of energy from animal fat intake and breast cancer (SRRE 1.02; 95 % CI 0.97, 1.07) was observed in the meta-analysis of these studies. In conclusion, the results of the present quantitative assessment are not supportive of a positive independent association between consumption of animal fat and breast cancer, although findings may be sensitive to the type of dietary instrument used in cohort studies.

Abstract
BACKGROUND Breast cancer has been increased in developing countries, but there are limited data for breast cancer risk factors in these countries. To clarify the risk for breast cancer among the Turkish women, an university hospital based nested case-control study was conducted. METHODS Between January 2000 and December 2006, a survey was prospectively conducted among women admitted to clinics of Istanbul Medical Faculty for examination and/or treatment by using a questionnaire. Therefore, characteristics of patients diagnosed with breast cancer (n = 1492) were compared with control cases (n = 2167) admitted to hospital for non-neoplastic, non-hormone related diseases. RESULTS Breast cancer risk was found to be increased in women with age (> or = 50) [95% confidence interval (CI) 2.42-3.18], induced abortion (95% CI 1.13-1.53), age at first birth (> or = 35) (95% CI 1.62-5.77), body mass index (BMI > or = 25) (95% CI 1.27-1.68), and a positive family history (95% CI 1.11-1.92). However, decreased breast cancer risk was associated with the duration of education (> or = 13 years) (95% CI 0.62-0.81), presence of spontaneous abortion (95% CI 0.60-0.85), smoking (95% CI 0.61-0.85), breast feeding (95% CI 0.11-0.27), nulliparity (95% CI 0.92-0.98), hormone replacement therapy (HRT) (95% CI 0.26-0.47), and oral contraceptive use (95% CI 0.50-0.69). On multivariable logistic regression analysis, age (> or = 50) years (OR 2.61, 95% CI 2.20-3.11), induced abortion (OR 1.66, 95% CI 1.38-1.99), and oral contraceptive use (OR 0.60, 95% CI 0.48-0.74) were found to be associated with breast cancer risk as statistically significant independent factors. CONCLUSION These findings suggest that age and induced abortion were found to be significantly associated with increased breast cancer risk whereas oral contraceptive use was observed to be associated with decreased breast cancer risk among Turkish women in Istanbul.
