Demographic and Socio-cultural Determinants of Intended and Unintended Pregnancies Among Women Under Cancer Treatment in Sistan and Baluchestan Province, Iran

Abstract
Background: One of the main concerns during cancer treatment is the occurrence of pregnancy due to its wide range of complications. Objectives: This study aimed to determine some influential factors on pregnancy during cancer treatment among women of reproductive ages that were under cancer treatment. Methods: This cross-sectional study investigated 133 women of reproductive age, who were under cancer treatment, as well as women who had undergone chemotherapy or radiotherapy up to one year ago in Sistan and Baluchestan Province. Data were collected from three medical centers in Zahedan from 2019 to 2020, using a researcher-made questionnaire. Results: Regarding the pregnancy rate, 23.0% of women had pregnancy during cancer treatment, including unintended (52.0%) and intended (48.0%) pregnancies that 55.0% of these pregnancies led to abortion, and 45.0% to livebirths. The results highlighted that during treatment women with and without pregnancy differed significantly in age (P = 0.001), ethnicity (P = 0.024), husband’s education level (P = 0.014), woman’s occupation (P = 0.021), couple’s agreement on number of children (P = 0.024), and physician consultation about contraceptives (P = 0.048). The main predictors of pregnancy were the woman’s age pregnancy (OR = 0.927, P = 0.011), occupation (OR = 0.358, P = 0.046), and ethnicity (OR = 2.49, P = 0.045). Conclusions: Considering the complications of pregnancy during cancer treatment, health planners should pay more attention to family planning for women under treatment, particularly in less developed regions.
