Abstract
Context:
Health, in all its aspects, is an important human right. There are various factors for the health of individuals with complex relationships with other cultural and social characteristics of a society that lead to inequality in health. Social determinants of health have a critical role in health matters; their impact on women's fertility and childbearing must be viewed as an important field to macrolevel and microlevel health scope decision-making and policy development.Objectives:
This study aims to extract and determine the social determinants that affect women's reproductive health based on existing studies and strong evidence.Methods:
This study was a systematic review that searched reputable medical databases and sites, including PubMed, Scopus, ISI, IranDoc, and SID, utilizing keywords like "social," "reproductive health/fertility/childbearing," and "women/female/woman". The scope of the study was limited to articles published between 2010 and 2019 due to the large volume of data available, and articles written in languages other than English or Persian were excluded from the review. The segregated articles concerning the abstract content were screened by two independent individuals to match the research objectives and keywords. The relevant abstracts were separated for review in the next step, and the full text of the obtained articles was read separately by two independent individuals to ensure their alignment with the research objectives. The articles were reviewed for quality and accuracy using the CASP tool, and those scoring above 75% entered the final stage of the study.Results:
In the initial database search, 1731 articles were found, and after removing duplicates, 1516 remained. Of these, 1313 were removed for not meeting the research objectives, leaving 203 articles for the next stage. After further review, 92 articles were excluded, resulting in 107 articles for further review. Out of these, 84 articles were evaluated for compliance with research objectives, with 26 articles entering the critical evaluation stage. All articles scored above 75% on evaluation tools and entered the final stage of information extraction.Conclusions:
The social determinants that impact women's reproductive health and childbearing, based on studies worldwide, include racial, ethnic, and national discrimination (for immigrants and minorities), micro and macroeconomic factors (income, costs of living, and healthcare), socio-cultural factors (education, employment, family norms), and socio-geographical factors (residence and urban status).Keywords
1. Context
Health, in all its aspects, is a fundamental human right. Health and welfare organizations worldwide strive to achieve the best health outcomes possible for their societies (1). Various determinants of people's health have a complex relationship with other cultural and social properties of a community, leading to health inequities (2). According to the definition of the World Health Organization (WHO), “social determinants of health (SDH) are the non-medical factors that influence health outcomes. They are the conditions in which people are born, grow, work, live, and age, and the wider set of forces and systems shaping the conditions of daily life, including income and social protection, education, employment, and job security, working life conditions, food security, housing, basic amenities, environment, early childhood development, social inclusion and non-discrimination, structural conflict, and access to affordable health services” (3).
Prioritizing women's health is crucial to achieving the fourth and fifth Millennium Development Goals (MDGs) (4).Women's health is influenced by physical, mental, sociocultural, and spiritual dimensions that are determined by the biological, social, political, and economic background of the community. It is important to consider the life cycle chart of women to promote their health in all dimensions (1).
Sexual and reproductive health are two approved goals of the world plan for sustainable development (5). The WHO emphasizes reproductive health as the main and basic part of well-being. People should have a responsible, satisfactory, and safe sexual life and freedom in reproductive ability and decision-making. Additionally, they should have access to safe, cost-effective, and acceptable ways for family planning (6).
Studies have shown that social determinants of health have a severe impact on the treatment of gynecological diseases, such as premature labor, unwanted pregnancy, infertility, cancers, and maternal mortality (7). Reproductive health impairment is responsible for 15% of the total burden of diseases and leads to women's disabilities around the world, accounting for 21.9% of DALY per year for women (8). The WHO has developed a framework to recognize opportunities and threats to encourage sexual and reproductive health services with high quality and accessibility (9).
2. Objectives
Through the current study, we aimed to identify and stratify the social determinants that are effective on women's reproductive health in order to design better interventions and plans to improve these issues more effectively and equitably.
3. Methods
The present study is a systematic review of all valid and available evidence on the social determinants affecting women's reproductive health, published between 2010 and 2019. All studies meeting the inclusion criteria were collected within this timeframe.
Inclusion criteria consisted of articles published in Persian and English languages, databases that could be fully accessed, and articles with accessible full texts. The screening was conducted in multiple stages, and cases that aligned with the research question and purpose in terms of title, abstract content, or the entire article and scored the necessary points in the critical evaluation stage were included in the study.
A structured question was designed using the PICO framework:
P: Women
I: Social components
C: -
O: Reproductive health
Data collection involved an initial search of sources to determine keywords related to the research topic. Keywords included (social), (determinant/indicator/index/indices/marker), (reproductive health/fertility/child bearing), and (women/female/woman). Authentic medical sites and databases, such as PubMed, Scopus, and ISI, and internal databases, such as IranDoc and SID, were searched using these keywords, and a specific search strategy was used for each database (Table 1).
Search Strategy Conducted for Databases
| Database | Search Strategy |
|---|---|
| PubMed | (“Social” [tiab] AND (“determinant” [tiab] OR “indicator” [tiab] OR “index “[tiab] OR” indices “[tiab] OR “marker” [tiab]) AND (“reproductive health” [tiab] OR “fertility” [tiab] OR “child bearing” [tiab]…) AND (“women” [tiab] OR “woman” [tiab] OR “female” [tiab]). *No filters were applied to increase search sensitivity except for the year of publication (2010 - 2019) |
| Scopus | ((ALL (social)) AND (ALL (determinant OR indicator OR index OR indices OR marker)) AND (ALL (reproductive health OR child bearing OR fertility)) AND (ALL (women OR female OR woman)) AND pubyear 2010 - 2019) |

Articles and studies on the social determinants of women's reproductive health were collected using EndNote 8 software, and numerous sources were reviewed based on the title of the research or article. The articles were separated by relevant titles and according to the keywords. At this stage, the extracted articles were reviewed by two independent researchers in terms of the content of the abstract to ensure alignment with the research objectives and keywords. Articles with relevant abstracts were included for full review. The search was then conducted to find the full text of the included articles in the previous step, and articles with available full text were selected for the next step. The full text of the articles was reviewed separately by two independent researchers, and articles that aligned with the research objectives advanced to the next stage. Cases that were not agreed upon by both researchers in the previous steps were re-examined and resolved by a third party. The articles were then reviewed and scored in terms of quality and accuracy using the CASP and STROBE tools for each type of study. Articles with a score above 75% entered the final stage of the study.
4. Results
In the initial phase of database searching, 1731 articles were obtained, but no relevant articles were found in Iranian databases. After removing the duplicates (215), 1516 articles remained. These articles were screened for title alignment with the research questions and objectives, resulting in the exclusion of 1313 articles. The remaining 203 articles were screened for abstract alignment, resulting in the exclusion of 3 articles due to lack of abstracts, 1 article due to non-Persian and English language abstracts, and 92 articles due to lack of content relevance. One hundred seven articles were selected for full-text review, but 13 articles were excluded due to unavailability of the full text.
Eighty-four articles remained for full-text review and compliance assessment with the research, resulting in the exclusion of 58 articles and the inclusion of 26 articles for critical appraisal. These 26 articles included 1 qualitative study, 19 cross-sectional studies, 1 review, 2 systematic reviews, 2 cohort studies, and 1 case-control study. Cross-sectional articles were reviewed using the STROBE tool, while other articles were assessed using the CASP critical appraisal lists, with all scoring above 75% and entering the final stage of data extraction.
The extracted determinants were categorized into four subgroups related to reproductive health:
(1) Fertility, which was directly mentioned in articles code 2, 4, 11, 12, 13, 14, and 15.
(2) Family planning, which affects reproductive health and fertility, was discussed in articles code 1, 6, 7, 9, 16, 17, 18, 19, and 20.
(3) Teen motherhood and pregnancy, which can indirectly affect reproductive health, were discussed in articles codes 3, 5, 21, and 22.
(4) Healthcare equity, which has effects on various aspects of reproductive health over short, medium, or long durations, was discussed in articles code 8, 10, 23, 24, 25, and 26.
Social determinants should affect reproductive health through direct or proximate components, including sexual activity (start time and frequency), contraceptive use (family planning), and history of complete pregnancy and full-term birth (10). The social indicators and components and their effects on reproductive health are presented in Tables 2-5, according to the groups defined above. Please see Appendix 1 for details of the extracted articles and data. The PRISMA diagram illustrating the study selection process is shown in Figure 1.

5. Discussion
Indicators that affect the early onset of sexual activity and early marriage can also impact other factors, such as early pregnancy, induced abortion rates, and contraceptive use, ultimately affecting reproductive health and fertility rates. Indicators such as adolescent pregnancy and early motherhood, while potentially increasing fertility rates, can paradoxically decrease maternal and child care and reduce overall reproductive health. Therefore, all physiological and socio-economic components of reproductive health and childbearing are interconnected.
In this section, we can integrate the previous classifications to understand the results of the studies better and mention the determinants in general.
5.1. Social Determinants That Affect Reproductive Health Status (Regardless of the Rate of Childbearing)
5.1.1. Immigration
A higher level of education in the family, high levels of support and family cohesion, favorable access and compliance with the school environment, and living with other immigrants can have a protective effect against sexual activity or early marriage, improving reproductive health (10). However, immigrants generally have lower levels of reproductive health (16).
5.1.2. Education Level in Women
Reproductive disorders have been observed in women with higher levels of education. However, due to less access to reproductive health services in uneducated and low-educated women, their reproductive health status is not favorable (11, 20).
5.1.3. Ethnic-Racial-National Discrimination
Minorities generally have lower levels of reproductive health. Blacks in the United States have lower levels of reproductive health due to poorer financial conditions and perpetual poverty in their generations, as well as a lack of access to reproductive health services. In Brazil, the fertility rate of blacks has also declined over time (21).
5.2. Social Determinants That Affect the Rate of Childbearing
5.2.1. Women's Empowerment Index in Society
A higher index of economic and socio-cultural empowerment increases childbearing (27).
5.2.2. Household Empowerment Index
A higher household empowerment index increases childbearing (18).
5.2.3. Women’s Education Level
A higher level of women's education reduces fertility (12, 13).
5.2.4. Husband's Level of Education
A higher level of education reduces childbearing (23, 27, 28).
5.2.5. Religion
Religion affects the level of access (23) and the use of family planning services, religious beliefs (17), and authority in decision-making, affecting childbearing (29). Various studies have associated Buddhism and Christianity with the highest rate of induced abortion (24, 30). However, in Burkina Faso, Islam and Christianity were associated with increased fertility (21). In Iran, childbearing is more common among the Sunni population (21).
5.2.6. Index and Degree of Women's Authority in Making Decisions About Reproductive Health and Childbearing
Increasing women's authority and autonomy in various aspects of decision-making, such as fertility and childbearing, disagreement with couples in decision making, and less age gap between couples with reduced pregnancy in adolescence, reduce childbearing (14, 15, 31).
5.2.7. Index and Degree of Family Authority in Decision-Making About Childbearing
Increasing the authority index in family decision-making leads to a decrease in childbearing (25).
5.2.8. Minimum age at First Marriage, Sexual Activity, or the Birth of the First Child in the Community
A lower age at which a woman gets married, starts having sex or gives birth to the first child leads to higher childbearing rates in that population.
5.2.9. The Rate of use of Mass Media and the Rate of Receiving Reproductive Health Education and Family Planning Messages from Mass Media
Increasing the overall rate of mass media use or receiving family planning messages reduces childbearing (24, 27).
5.2.10. Micro and Macroeconomic Determinants
A low level of national income (26), low socioeconomic class, poor socioeconomic situation of the province of residence, an increase of household expenditure, an increase of per capita cost of education, an increase of average cost or rent of housing in residential areas, reduce fertility. In some societies, a lower wealth quintile has led to a decrease in fertility by increasing unsafe abortions and compromising reproductive health (30). On the other hand, the lowest quintile welfare in some communities, due to a 40% reduction in the possibility of using long-term contraceptive methods and access to family planning services, had more children (13). However, in other societies, the poor had fewer children due to more use of contraceptive methods (19). Paradoxical effects require specific studies for each region and community.
5.2.11. Average Ideal Number of Children in the Community and the Place of Residence
The higher the ideal number of children and desired size of the family in the norm of society, the higher the childbearing rate in that society (19, 25, 27).
5.2.12. Status and Employment Rate of Women
In working women and societies that have a higher average of women's employment, childbearing decreases (24, 26).
5.2.13. Status, Class, and Employment Rate of Men
Unemployment or a lower occupational class or employment rate in men reduces childbearing. However, another study showed that unemployment in the family increases the rate of adolescent pregnancy (22).
Different employment conditions can have varying effects on reproductive health and the level of expenditures, which should be carefully and separately examined in different communities.
5.2.14. Child Sex Preference and the Number of Children in the Family
Child sex preference and the number of children in the family, as well as the decision of the family to have children in the future, have been shown to affect childbearing rates. Studies indicate that when the number of children in the family reaches 2 or 3, childbearing decreases (19, 31). Additionally, having a son in the family reduces the likelihood of further childbearing (19). However, couples who have a decision to have children in the future and do not plan to have them at the moment may intermittently use contraceptive methods, resulting in a decrease in childbearing (13).
5.2.15. Women's Age
Women's age is a crucial factor that affects reproductive health outcomes. The highest rate of contraceptive method use is observed in the age group of 25 to 35 years (19). However, the rate of long-term contraceptive method use among this age group is lower (13), and the rate of induced abortion or termination of pregnancy is higher among older women, particularly those over the age of 35 (24). The highest rates of pregnancy and premature birth occur between the ages of 18 and 19 (15). Women's decision-making authority about pregnancy is lowest in the age group of 15 to 19 (29). Women in the age group of 10 to 19 have the least access to reproductive health services and prenatal care (32). Therefore, this age group is one of the most vulnerable in terms of reproductive health and requires targeted interventions.
5.2.16. Indigenousness or Immigration
Indigenousness or immigration can affect reproductive health outcomes. Migration can lead to numerous discriminations and deprivations for the immigrant population, with reproductive health, such as early marriage, early sexual activity, and unintended pregnancy, being more prevalent among immigrants (26, 33). However, as immigrant generations advance, such as the children and grandchildren of early immigrants, these inequalities decrease, and the reproductive health status improves (33).
5.2.17. Residence
Residence, i.e., urban or rural, can also affect reproductive health outcomes. Urban life, despite better access to reproductive health services (34) and greater women's authority in making reproductive health decisions (29), may lead to lower fertility rates due to the increased use of contraceptive methods (35) and intentional termination of pregnancy (26). Total fertility rates are higher in rural areas (12).
5.2.18. The Marital Status of Women
The marital status of women is also associated with increased fertility in more favorable and healthier conditions (24).
As mentioned, social determinants can increase inequality in the use and access to reproductive health services, family planning, and prenatal care, leading to disparities in reproductive health outcomes and optimal childbearing of women. Although some inequalities in access to services, such as those between rural and urban areas or different levels of family income, have decreased over time due to local health system interventions, rural-urban inequalities in fertility rates and among different income groups persist (35). Racial-ethnic-national discrimination has also been identified as an important factor of inequality in reproductive health. The issue of racial discrimination, especially as it pertains to minorities, is rooted in slavery. Black slave women were sexually abused to provide more economic benefits to their masters by giving birth to more slaves. Still, the fertility rate of blacks has steadily declined over time (11). Racism in its various aspects, such as structural racism, interpersonal racism, and racism in midwifery, perpetuates health disparities. More employment of women in providing services without controlling racist beliefs and cultures, disproportionate distribution of forces in urban and rural areas, and racial incompatibility of the workforce providing health services with residents of areas, especially rural areas, are among the reasons for not reducing health inequalities (36). The issue of minorities can also be considered from other perspectives in some countries, as membership in certain groups or tribes or belief in a particular religion can lead to the unjustified superiority of one group over others and exacerbate health inequalities (29). Cultural and belief differences must be taken into account.
Another important component that affects childbearing rates is the economic determinant, which can have an impact at the micro and macro levels. Factors such as maternity costs and related services should also be considered; as the average cost of these services increases, families desire to have more children, and childbearing decreases (37). Inadequate access to healthcare facilities due to long distances from the place of residence to health service providers is another important reason for reduced access and, consequently, reduced reproductive health (17). Some areas experience lower access to health services, leading to increased inequality and reduced reproductive health (17). Road problems, lack of transportation facilities, and lack of security, despite the lack of significant distance from service centers, are also important barriers to accessing health services and lead to increased inequality and reduced reproductive health in some areas (17, 36).
In addition to all of the above, non-health sector factors play a crucial role in reducing inequality in reproductive health. Policies developed to govern the country must be reviewed and adjusted for their effects on population health conditions. “Health in All Policies” is a critical issue that is a main pillar of community health promotion interventions. Local policymakers must address inequalities in health in their region by developing innovative and localized policies (38).
5.3. Limitations in the Study
(1) The scope of this study was restricted to articles published between 2010 and 2019 due to the extensive volume of data available.
(2) Articles that were written in languages other than English or Persian were excluded from the review.
(3) A few extracted articles could not be accessed in their entirety or abstract form and, therefore, were excluded from the study.
5.4. Study Strengths
This study has a distinctive approach in which all facets of women's reproductive health and childbearing, along with the social determinants that influence them, were comprehensively examined.
5.5. Conclusions
To promote women's reproductive health and childbearing, it is necessary to consider the social determinants that indirectly and significantly impact their health, as with other health aspects. Various studies worldwide have identified the most important social determinants that affect reproductive health and childbearing, including racial-ethnic-national discrimination (in the case of immigrants, racial and religious minorities), micro- and macro-economic factors (household welfare index, average family income, national income level, costs of living and education, costs of reproductive and obstetric health services), socio-cultural determinants (level of education, employment, socio-economic-cultural class of the family, socio-cultural norms such as the ideal number of children in the family, child sex preference, common age for marriage and sex, and marital status), and socio-geographical factors (country, province and region of residence, and urban status).
In the formulation of health-oriented policies across the country, special attention should be given to these determinants.
