ABSTRACT
INTRODUCTION: Breast cancer is one of the most important and common types of cancer in most countries of the world and its incidence are increasing in Iranian women. Understanding its contributing factors is important in planning for prevention. This study was conducted to investigate the association between aluminum-containing antiperspirant and hair color use with breast cancer. METHODS: In this observational cross-sectional descriptive study, 384 patients with breast cancer referred to selected hospitals of Tehran University of Medical Sciences in 2017 and 384 person as control group were randomly selected. The anti-perspiration use of aluminum-containing and hair color was compared. In this study, data were collected and descriptive and inferential statistics were used to analyze them. Absolute and relative frequency distribute tables, mean, and standard deviation were used to descriptive statistics. Chi-square and independent t-tests were used for data analysis. RESULTS: The use of antiperspirant was similar in this study, with 23.2% of breast cancer patients and 22.4% of control group using antiperspirant (P = 0.796). Frequency distribution of the use of hair color was similar among the studied subjects and 35.9% of breast cancer patients and 32% of control group consumed hair color (P = 0.253). CONCLUSION: Based on the results, it can be concluded that there is no significant relationship between the use of aluminum-containing anti-perspiration and hair color with breast cancer.
ABSTRACT
BACKGROUND AND AIM: Endometriosis is a chronic and common disease in the world in which living endometrium stroma and glands are found outside the uterus. The presence of this tissue in different parts of the body causes various symptoms that have an adverse effect on women's quality of life, fertility rate, and productivity. The aim of this study was to determine the relationship between lifestyle and endometriosis in infertile women referred to the selected hospital of Tehran University of Medical Sciences. MATERIALS AND METHODS: The nature of this study is descriptive-comparative. The convenient sampling method is used among all infertile women undergoing laparoscopy, in group 1 (with endometriosis diagnosis) and group 2 (without endometriosis). The sample size is estimated to be 125 in each group according to the Cochran formula and with the alpha coefficient of 0.05. Data analysis was done using SPSS software version 20. RESULTS: There was a direct and significant relationship between the probability of developing endometriosis and age, education level, and regularity of menstruation variables so that with the increase in each of the above variables, the probability of the disease increases. There was a significant and inverse association between the incidence of endometriosis and the body mass index (BMI) variable, which means that with the increase in this variable, the risk of endometriosis in individuals is reduced. CONCLUSION: This study suggests that high age, low BMI, menstrual cycle regularity, and education have a strong relationship with endometriosis in infertile women, and there was no relationship between lifestyle and the incidence of endometriosis among them.
