Current contraceptive use varies depending on the age of women: the pill was the most widely used method in all age groups of women, with the exception of those aged 45 to 49, who were more likely to use periodic abstinence. A similar picture was found in women aged 30 to 49, who were more likely to be sterilized than younger women. Islam  also found similar evidence that the contraceptive prevalence rate was lower in younger women than in older women from a cross-sectional study in Narsingdi district under Dhaka division. Numerous studies have shown that the use of contraceptives can significantly reduce fertility and ultimately improve the health of both mother and child. However, contraceptive use has not increased as women`s level of education has increased, probably because men are the main decision-makers of a family in Bangladesh. On the other hand, the likelihood of using contraception is positively associated with women`s occupation, where working women are more likely to use contraceptives than unemployed women. Chuang et al.  and McNicholas et al.  had shown that sexually active women of childbearing age were significantly less likely to use contraception than women of normal weight. We also found that overweight women in Bangladesh were 30% less likely to use contraceptives than normal-weight women.
Although many studies have shown that the difference in the age of husband and wife is related to contraceptive use [47, 48], we have found that the difference in husband`s age with wife`s education and husband`s education both play an important role in contraceptive use, while the husband`s profession remains insignificant. With the increase in the husband`s level of education, the prevalence of contraceptive use increases, as the husband`s level of education has influenced the use of male sterilizations and condoms , although men in any case play an important role in the introduction of contraceptives when there is communication between husband and wife on reproductive issues . Not surprisingly, women who currently live with their husbands and have been sexually active in the past year were more likely to use contraception. This study has several strengths compared to other studies conducted in a similar context. He followed a rigorous statistical technique by taking into account individual sample weights when presenting the actual national result and using mixed-effect logistic regression models to correctly identify factors associated with contraceptive use. Another strength of the study was that it took into account a large number of potential factors that may have affected contraceptive prevalence. There may be other broader factors related to contraceptive use, but to our knowledge, our current model is the first rigorous model to identify a large number of covariates associated with Bangladeshi women and their respective husbands that directly affect contraceptive use. The results of this study are important for program managers involved in family planning in Ethiopia.
Our knowledge of how aspects of individual and domestic factors influence a woman`s use of modern contraceptives can be used by family planning program managers to shape the development of family planning and support programs. Health promotion can use community conversations, which include community-wide discussions, to address cultural beliefs and customs to increase support for family planning. In addition, spatial distribution using clusters with low and high prevalence can be used to identify areas where existing contraceptive use is above or below expectations. Areas with higher than expected use may be examples of best practices that providers and decision-makers could use to improve policies and practices, and areas with lower use could be targeted for future interventions. The importance of socio-economic factors also supports development policy, which removes economic barriers to the use of services. Our results showed that women who participated in community conversations and were visited by a health care provider were more likely to use modern contraceptives than their peers. A study conducted in Ethiopia showed that when respondents went to a health clinic and received family planning advice or services, there was a significant association with the use of modern contraceptives . Another study  found that the use of family planning methods was positively correlated with women`s exposure to information about family planning methods on television, radio or newspapers. In our analysis, there was no association with exposure to mass media and visits to health facilities. On the contrary, attending community conversion sessions and visiting health care providers were factors that contributed to the use of modern contraceptives. This implies that in the Ethiopian context, individualized counselling approaches and community conversations are better alternatives than mass media to address women`s concerns and increase the use of family planning methods. Although family size and partner education were found to be factors influencing the use of modern contraceptives in other studies, these factors did not independently predict modern contraceptive use in our analysis.
Geographical variation in conceptual use requires further research, particularly the identification of contextual factors that contribute to contraceptive uptake in high-prevalence and low-prevalence clusters. The original meaning of the word contraception is contraceptive technique . Contraception is generally defined as the intentional prevention of conception or impregnation during sexual activity by artificial means such as the use of various devices, means, medications, sexual practices or surgical interventions. The main purpose of these methods is to prevent sperm from reaching the egg by using condoms, diaphragms, etc., inhibiting ovulation, preventing implantation, etc. It was known that in Bangladesh, almost half of all deaths among women of childbearing age were caused by problems with pregnancy and childbirth and unsafe abortions [2, 3]. In addition, women under the age of 18 are more likely to die in childbirth because their bodies are not fully adult, they are not physically or emotionally willing (including financially) to carry and care for a child, and their babies tend to have low birth weight and cope with a variety of diseases that result in a greater likelihood of dying, before reaching their second birthday [4, 5]. Many scientists have found that most of these complications, especially pregnancy complications and deaths, could be prevented by good family planning , as family planning has great benefits for the mother, children, father and family. Contraception is one of the key elements of family planning and can therefore help prevent poor health of women and children, as well as domestic food insecurity. The use of contraceptives such as condoms can also help protect against the spread of sexually transmitted infections, including HIV.
In addition, hormonal methods can help relieve irregular bleeding and pain during a woman`s monthly bleeding. .
