Background: Breast cancer is the most common type of cancer in women and is influenced by reproductive factors perceived by women worldwide.Aims: To identify the reproductive risk factors of breast cancer in newly diagnosed cases and to find out the strength of association of the risk factors with the breast cancer. Material and Methods: A hospital based case-control study was conducted in Satara district, India during year 2009 to 2011 among newly diagnosed cases of breast cancer and matched controls. A total of 434 participants including 217 cases and 217 controls were enrolled by purposive sampling technique from selected hospitals of study area. The information was collected by employing pre-tested questionnaire by utilizing interview method. Statistical Analysis used: Descriptive statistics, Odds ratio and Chi-square test was used to find out strength of association and statistical significant difference. Results: Highest proportion [31.80%] breast cancer cases was in age group 40-49 years with lowest age of 25 years at diagnosis of the disease. A very high proportion of both cases [88.02%] and controls [67.28%] were Hindu by religion and were from rural residence. Maximum proportion of breast cancer cases were housewives [63.59%], literate [71.42%] and from upper economic class [56.68%]. The proportions of cases were higher as compared to the controls with respect to risk factors like unmarried status, nulliparity, history of abortion, post menopausal status, absence of breast feeding and the history of exposure to hormonal contraceptives. The risk of getting breast cancer as indicated by Odds ratio was 8 times higher in unmarried women, 2.8 times in nulliparous women, 2.4 times with post menopausal status, 10.4 times with absence of breast feeding, 1.5 times with exposure to hormonal contraceptives and 4.5 times with history of ovarian disease respectively. Conclusion: The reproductive risk factors such as unmarried status of women, nulliparity, menopause, absence of breast feeding, history of ovarian disease and use of contraceptives were strongly associated with breast cancer.Bangladesh Journal of Medical Science Vol.14(3) 2015 p.258-264

Reproductive Risk Factors

Kanker payudara paling banyak ditemui pada perempuan dan merupakan penyebab kematian kedua setelah kanker leher rahim.Penyebab kanker payudara tidak diketahui dengan jelas karena multifaktor. Bukti epidemiologi menunjukkan bahwa terdapat tiga faktor penyebab terjadinya kanker payudara yaitu faktor hormonal, faktor genetik dan faktor lingkungan. Provinsi Sumatera Utara menempati urutan kelima kejadian kanker payudara di antara seluruh provinsi yang ada di Indonesia. Tujuan penelitian ini adalah untuk menganalisis hubungan antara faktor risiko reproduksi dengan kejadian kanker payudara. Jenis penelitian ini adalah kasus kontrol dengan pendekatan retrospektif. Subjek penelitian adalah perempuan penderita kanker payudara yang mendapatkan perawatan dan pengobatan di Rumah Sakit Umum Pemerintah H.Adam Malik dan Rumah Sakit Umum Daerah dr.Pirngadi Medan. Jumlah sampel 100 responden yang terdiri dari 50 kasus dan 50 kontrol. Analisis yang digunakan adalah analisis bivariat menggunakan uji chi-square dan analisis multivariat menggunakan regresi logistik ganda. Hasil penelitian menunjukkan bahwa faktor risiko yang berhubungan dengan kejadian kanker payudara berdasarkan analisis bivariat adalah usia menarche (p=0.001), paritas (p=0.001), usia kehamilan pertama (p=0.001) dan menyusui (p=0.002). Pada analisis multivariat menunjukkan bahwa keempat faktor risiko yang diteliti secara statistik bermakna (p<0.05), yaitu usia menarche (OR=4,41;95%CI: 1,33 ̶14,63), paritas (OR=6,38;95%CI: 1,57–25,90), usia kehamilan pertama (OR=7,91;95%CI; 1,86−33,60) dan menyusui (OR=4,24;95%CI:1,22–14,76). Dapat disimpulkan bahwa faktor risiko reproduksi yang berhubungan dengan kejadian kanker payudara adalah usia menarche<12 tahun, paritas 1–2, usia kehamilan pertama 20–30 tahun dan tidak menyusui. Faktor risiko yang paling dominan dalam penelitian ini adalah usia kehamilan pertama.Kata kunci: Faktor risiko, kanker payudara, reproduksi AbstractBreast cancer is most commonly found in women, and is the second leading cause of death after cervical cancer. Due to its multifactorial nature, the cause of breast cancer is indeterminate. Epidemiological evidence suggests that there are 3 possible factors contributing to the occurrence of breast cancer, namely hormonal, genetic and environmental factors. North Sumatra is the 5th province having the highest breast cancer prevalence among all other provinces in Indonesia. The purpose of this study was to analyze various reproductive risk factors contributing to breast cancer incidence in women. The study was a retrospective case-control. Subjects were women with breast cancer who received care and treatment in H.Adam Malik General Hospital and dr.Pirngadi Medan General Hospital. The sample size was N=100 (n=50 – case group; n=50 – control group). The data were analyzed using bivariate analyses (Chi-square tests) and multivariate analyses (multiple logistic regressions). Bivariate analyses showed that reproductive risk factors associated with breast cancer were menarche period (p=0.001), parity (p=0.001), age of first pregnancy (p=0.001) and breastfeeding (p=0.002). Moreover, multivariate analyses showed statistically significant correlations (p <0.05) between the four reproductive risk factors and breast cancer incidence, including menarche period (OR=4.41, 95% CI: 1.33 ̶ 14.63), parity (OR=6.38, 95% CI : 1.57 ̶ 25.90), age of first pregnancy (OR=7.91, 95% CI: 1.86 to 33.60) and breastfeeding (OR= 4.24, 95% CI: 1.22 ̶ 14.76). In conclusion, the reproductive risks associated with breast cancer incidence in women were the menarche period of <12 years, parity of 1 ̶ 2 times, first pregnancy age of 20 ̶ 30 years old and non-breastfeeding status. In this study, the age of the first pregnancy was found to be the most dominant factor. Key words: Breast cancer, reproductive, risk factor
