Introduction
The demographic shift toward delayed motherhood is evident not only in high-income countries but across regions worldwide. In wealthier nations, the age at which women have their first pregnancy has consistently risen over time1. According to data from the United States, the proportion of births among women over 35 has doubled since 1990, accounting for nearly 20 % of births by 20212. In Western and Northern Europe, this trend became apparent in the early 1970s and subsequently extended to other regions3. Evidence of this increase in Latin American countries remains limited and yields contradictory results; while some studies report that early motherhood persists with no significant trend toward delayed maternity4-5, other data indicate that reproductive patterns are indeed shifting in these countries3,6.
In Colombia specifically, reports indicate that fertility declined after 1995 despite changes in the pace of fertility inflation for first births. However, a slowdown was observed in the trend toward earlier motherhood among younger cohorts, although this was not statistically significant from a demographic perspective5.
Furthermore, a study conducted by the National University of Colombia exploring the prevalence and associated factors of pregnancy in women over 35 years of age found that between January 2011 and October 2015, there were 12,846 pregnancies which occurred in women over 35, with 19.8 % of these women aged 40 or older7.
Although the trend of delaying pregnancies among women has been extensively studied, it remains a topic of considerable debate. According to a review by Mills et al., reasons for this trend include effective contraception, higher levels of female education, greater participation in the labor market, changes in romantic relationships, economic uncertainty, and shifts in values and norms regarding parenthood8.
From a biological perspective, there is substantial scientific evidence regarding the consequences of pregnancy based on maternal age; however, certain psychosocial aspects have been less thoroughly examined.
The recent global economic crisis has influenced job stability and led to increased workplace flexibility, allowing more women to work during and after pregnancy6. The process of returning to work for women who have chosen to postpone motherhood can be challenging, as negative perceptions of motherhood in the workplace may be internalized9, and there is significant stress involved in balancing motherhood with work demands10.
Regarding the return-to-work process, a woman’s social support network plays a crucial role in managing the stress associated with transitioning from maternity leave back to work. Social support is defined by the extent to which social relationships meet specific emotional, instrumental, affective, or tangible needs, as well as the degree of social interaction11. Studies by Ribeiro et al. and Ma et al. show that positive social support affects how pregnant women handle stressful situations, enabling them to more easily adapt to their maternal role12,13. One of the most important sources of this social support is family, to whom mothers typically turn for assistance; however, the effectiveness of family support largely depends on the functionality of the relationship14. Well-functioning families are characterized by open communication, emotional closeness, low levels of conflict, clear roles, and adaptability15.
In Latin America, and specifically among pregnant women over 35 in Colombia, evidence on family functionality, social support, and its influence on work reentry is scarce. This information would facilitate the design of plans, programs, and projects to support work reintegration.
The primary objective of this study was to identify and describe work reentry, family functionality, and social support among women who became pregnant after age 35 in Medellín and the metropolitan area of Antioquia, Colombia.
Materials and methods
Design
The study was conducted between June 2023 and January 2024, framed within the empirical-analytical paradigm, with a quantitative, descriptive design that aimed for analytical insights, using primary data sources. Data were collected on participants’ sociodemographic, work, and family characteristics, as well as their current age and age at the time of pregnancy.
Population and sample
The target population was women residing in Medellín and the metropolitan area who experienced pregnancy after age 35. A non-probabilistic, convenience sampling method was used, including women attending medical check-ups at private institutions in the city. The research team invited women who met the inclusion criteria to participate, ensuring voluntary participation after explaining the study’s purpose and procedures.
Procedure
Sociodemographic, work, family, and age information (current and at pregnancy) was collected through a self-administered Google Forms survey. Personal identifiers, such as name or ID, were not recorded to ensure participants' anonymity.
Variables/instruments
Sociodemographic variables included educational level, socioeconomic status, area of residence, marital status, current age, and age at the time of pregnancy. These variables helped identify work access or requirements and the opportunity to delay motherhood.
Age at pregnancy was the sole limiting variable, as it defined the study population for evaluating other items.
Another variable was satisfaction with work reentry, measured through a questionnaire developed by the researchers, considering both operational and logistical aspects, as well as motivation and socialization in the workplace. Examples of indicators for satisfaction with the work environment included: “I am satisfied with the benefits I receive at my job”, “My job allowed me to advance in my professional growth”, and “Upon returning to work after pregnancy, my work environment was affected”.
Family functionality was assessed through the Family APGAR, a five-point Likert scale developed by Smilkstein in 197816, widely used and validated for characterizing this aspect due to its brevity and ease of comprehension. Examples of indicators for family functionality included: “I am satisfied with the help I receive from my family when I have a problem or need”, “I am satisfied with how we discuss and share problems within my family”, and “I am satisfied with how my family accepts and supports my desire to pursue new activities”.
Finally, social support was measured using the Medical Outcomes Study Social Support Survey (MOS-SSS), developed by Sherbourne et al.11 and validated in Colombia in 2011, showing a favorable Cronbach's alpha ranging from 0.921 to 0.73617. This instrument provided insights into emotional, instrumental, affective, and positive social interaction dimensions, along with an overall social support index. Additionally, an Excel template was designed to compile data on all variables.
Statistical methods
Quantitative variables were presented as means or medians with their respective measures of dispersion, depending on variable distribution. Qualitative variables were summarized using absolute frequencies and percentages. Mean comparisons were performed using Student’s t-test for independent samples or the Mann-Whitney U test, as applicable.
For group comparisons, chi-square and Fisher’s exact tests were used for categorical variables, while ANOVA and Kruskal-Wallis tests were applied for continuous variables (depending on their distribution). A p-value <0.05 was considered statistically significant, and all analyses were conducted using SPSS software version 25.
Results
Sociodemographic and occupational characteristics
The data analysis was based on 106 women who experienced pregnancy after age 35 in the department of Antioquia, Colombia, and who were employed both before and after their pregnancy. The majority of participants were between 35 and 40 years old at the time of pregnancy. Currently, 51 % reside in the city of Medellín, 68 % have an undergraduate or higher level of education, over two-thirds belong to an upper-middle socioeconomic class, and 87 % have a spouse.
Regarding psychiatric history, one-fourth of the participants reported postpartum depression, and only 10 % currently have a psychiatric condition. Furthermore, 93 % of the participants were employed at the time of pregnancy, and of these, approximately 86 % returned to work postpartum.
As supplementary data, 50 % of the women were paid employees, and 90 % of the total had health insurance coverage (Table 1).
Table 1 Sociodemographic and occupational characteristics
Family functionality
Of the participants, 43.8 % rated their family functionality as normal, while the remaining 56.2 % reported some level of dysfunction, with severe dysfunction being the least common at 12.4 % (Table 2).
Work reentry
Of the participants, 49 % considered their work reentry following pregnancy after age 35 to be highly satisfactory, 48 % rated it as moderately satisfactory, and only 2.8 % rated it as unsatisfactory (Table 2).
Perceived social support
The maximum global score on the social support scale was 94 points, with participants achieving a mean score of 78.63 and a standard deviation of 17.04. This tool allowed for the determination of overall social support perception and enabled the identification of dimensions that provided a more detailed characterization.
The emotional support dimension assessed three levels: real demonstrations of affection, such as esteem, care, empathy, and the availability of people able to provide such support; the presence of affective relationships within the individual’s network; and the participant’s perception of these support manifestations, specifically how loved or admired they feel. This dimension, where the presence of these three components influenced affective well-being, exhibited the lowest score based on the obtained mean.
Instrumental support evaluated the type of material or assistance support, such as financial or material resources to achieve something, help with domestic tasks, and care for children or a family member with an illness. Social interaction, meanwhile, assessed the respondent’s and surrounding individuals' availability for gatherings, recreation, and enjoyment; these two dimensions had similar intermediate mean scores of 16.37 and 16.64, respectively, where the maximum score for both was 20 points.
Finally, the dimension with the highest mean score was affective support, with 13.05 points out of a maximum of 15. This was defined as the participant’s ability to communicate personal issues, relevant events, conflicts, or intimate matters that require understanding and help (Table 3).
Table 3 Global social support and its dimensions among participants
| Social support | Mean | Standard deviation |
|---|---|---|
| Global score | 78.632 | 17.0407 |
| Emotional support | 32.557 | 7.7276 |
| Instrumental support | 16.377 | 3.8974 |
| Social interaction | 16.642 | 3.8401 |
| Affective support | 13.057 | 2.7906 |
When analyzing the perception of social support among women who were pregnant over the age of 35 according to their sociodemographic characteristics, it was observed that the global, emotional, and instrumental social support, social interaction, and affective support scores were, on average, higher among women with a university or higher educational level compared to those with up to secondary education; however, these differences were not statistically significant (Table 4).
According to the socioeconomic classification of the participant's household (low/high), it was noted that both global social support and all its dimensions were, on average, higher for women in higher socioeconomic strata compared to those in lower strata, with a statistically significant difference observed in affective support.
Regarding marital status, women who were pregnant over the age of 35 and lived with a partner perceived higher global social support and in all dimensions compared to those not living with a partner. These differences were not statistically significant (Table 4).

Work Reentry According to Family Functionality and Perceived Social Support
When analyzing the relationship between work reentry and family functionality among the participants, it was observed that those with normal family functionality reported a higher frequency of highly satisfactory work reentry (62 %). In contrast, this percentage significantly decreased among those who reported severe family dysfunction.
Regarding social support, emotional support was, on average, higher for participants who rated their work reentry process as highly satisfactory (35.98 ± 5.98), making it the most highly rated support dimension among these women. Both instrumental support and social interaction also showed the same trend, with higher averages among women who experienced satisfactory work reentry.
The affective support dimension, with means of 14.30 ± 1.63 for highly satisfactory work reentry and 11.71 ± 3.25 for moderately satisfactory, also showed significant differences according to work reentry satisfaction.
Family functionality and social support in all dimensions presented statistically significant differences based on work reentry satisfaction (Table 5).

Discussion
This study analyzed the work reentry process of a group of women in Antioquia who experienced pregnancy after age 35, examining its relationship with social support and family functionality.
According to demographic characteristics, 88 % of the women surveyed had their pregnancy between ages 35 and 40, consistent with previous studies conducted in Colombia in 2011, where the average maternal age was 37.6 years7.
In terms of educational level, Baranda-Nájera et al.18, in their 2014 study on advanced maternal age in a Mexican hospital, found a higher percentage of women with only basic education, unlike the findings of the present study, in which 82.1 % of participants had an education level higher than secondary school. This difference may be explained by the convenience sampling used in this study, where women attending medical appointments in Medellín were invited to complete the survey.
Despite differences with the Mexican study, the advanced educational level among women who delayed motherhood beyond 35 aligns with the hypothesis that, socially, modern women prefer to achieve greater economic and job stability before pursuing motherhood. This has been corroborated by studies by Ospina et al.7 and Waldenström19, indicating that both roles require intensive participation8.
Perception of social support
In this study, participants reported, on average, good overall social support and in various dimensions, with a mean global score of 78 out of 90. Instrumental support (referring to economic, material, or in-person support) had a mean score of 16.2, while social interaction had a mean of 16.6 out of a possible 20 for both dimensions. This high level of social support across all dimensions aligns with data from other studies, which found that women who became mothers later in life more frequently reported better family backgrounds and higher educational levels than childless women in the same age group20.
Regarding social support, a study conducted in Concepción, Chile, in 2013 reported that the highest-scoring items for participants were emotional support (defined as the presence of individuals with whom they could share problems) and affective support (viewed as a source of comfort)21. These findings are consistent with the results of this study, where the mean score for emotional support was 32.55 out of 40 points and 13.05 out of 15 points for affective support, with participants also reporting high levels of instrumental support and social interaction.
In Colombia, studies conducted in Tunja7 between 2011 and 2015 and in Bogotá21 in 2014, focusing on women of advanced maternal age and their perceptions of social support and lifestyle, revealed a different social reality. Most of the women studied faced challenging work conditions, making pregnancy after 35 a significant challenge.
Perception of social support according to sociodemographic characteristics
Sociodemographic and socioeconomic characteristics among pregnant women indicate that greater material and educational resources are associated with higher perceived social support. In this regard, a study conducted in Brazil22 among high-risk pregnant women found, similar to our results, that as the educational level of pregnant women increased, so did perceptions of overall social support and its various dimensions, with differences in emotional support being statistically significant (p = 0.015). Likewise, a study conducted in Santa Marta, Colombia, also reported that higher socioeconomic status among pregnant women was associated with greater perceived social support23.
In our study, all dimensions of social support were higher among women with a partner compared to those without. Similarly, a study by Carvalho et al.22 conducted in a maternity service in northwestern Rio Grande do Sul (Brazil) from November 2021 to April 2022, found that high-risk pregnant women with a partner reported greater perceived emotional and affective support but lower levels of material support, informational support, and positive social interaction.
In our study, global social support and all its dimensions were deemed satisfactory, with maternal age emerging as a factor explaining higher perceived social support, similar to a study conducted in Lima, Peru, where older expectant mothers reported higher levels of social support24.
Family functionality
In our study, over 50 % of pregnant women reported some type of family dysfunction, which aligns with a study from Cali, Colombia, that analyzed family functionality among pregnant women attending a prenatal health program during the post-COVID-19 pandemic isolation period25.
Regarding family functionality, Hawkins et al.26 posited that married women or those in stable relationships tend to have a more positive perception of their family’s functionality, establishing-similar to Alipur et al.-that the marital relationship is a fundamental element in gestation and family dynamics27. Our study revealed that although 82.1 % of participants were in stable relationships, only 43 % rated their family functionality as normal, with more than half self-reporting some level of dysfunction.
A scoping review covering 24 studies on the psychological impact of advanced maternal age on mothers and their children found that family functioning, social support, and maternal attitudes improved after age 30, highlighting that some benefits may counterbalance certain biological disadvantages28. Consistently, other studies have reported that, despite higher prenatal depressive symptoms among women pregnant after age 35, social support (particularly objective and subjective support), family functioning, and maternal attitudes improved with age29-30.
Family functionality and work reentry
The relationship between normal family functionality and satisfactory or moderately satisfactory work reentry was positive, as none of the women with normal family functionality reported an unsatisfactory work reentry, which may act as a protective factor in work reintegration19.
In the study by Kang and Kaur31 on pregnant women in India employed in banks and private sector insurance companies, family and partner support were found to be crucial for work reentry and career planning. One possible explanation could be that women who felt that their family/partner listened to their work-related problems and suggested solutions felt understood by their family/partner, who were invested in their career growth. Family/partner support strengthened the women emotionally by showing interest and concern for their professional goals.
Social support and work reentry
A key dimension of family solidarity during pregnancy was the exchange of instrumental and emotional support, which was essential for work reentry. In our study, women who were pregnant after age 35 generally perceived higher social support across all dimensions. These findings support evidence regarding factors associated with increased social engagement in the labor market among mothers. According to the theory of planned behavior, which posits that behaviors are based on prior intentions to engage in those behaviors, pregnant women over 35 may have positive attitudes toward work32, which in turn may depend on their perceived support for returning to work33.
For women, the transition from maternity leave to work reentry becomes a critical event, posing a significant barrier in essential aspects of motherhood, such as time with the newborn and the duration and exclusivity of breastfeeding34.
Social support is a resource linked to self-efficacy, particularly among adolescent mothers35. This self-efficacy could be a strong predictor of work reentry in women over 35, similar to its role in occupational groups facing health challenges36.
A study aimed at describing the characteristics of women returning to work within the first postpartum year and identifying specific occupational and health factors associated with work reentry among women who worked during pregnancy37 showed that women over 35 had a lower work reentry rate compared to those under 35. However, when adjusted odds ratios (ORs) were calculated based on occupational and economic variables, this difference was not significant, highlighting the importance of contextual factors in work reentry.
Strengths
Most studies addressing work reentry after pregnancy focus on predominantly young women, leaving pregnant women over 35 underrepresented. This study, therefore, focused solely on women who became mothers after this age, recognizing that their social, economic, occupational, and family characteristics differ, and analyzing aspects that may present unique challenges in motherhood for this age group.
Similarly, most scientific evidence originates from countries where public support services play a significant role in work reentry. To date, this study is among the first in Latin America to explore the role of social support and family functionality among women who were pregnant after age 35.
Limitations of the study
The findings of this study should be interpreted with the following limitations in mind: the population sample is not representative of the Colombian population as data were collected through convenience sampling. Participant data were self-reported, which may have been subject to recall bias.
Conclusion
Work reentry was considered satisfactory by half of the participants who became pregnant after age 35. Family functionality and a positive perception of social support were factors that contributed to the positive assessment of work reentry.
Further research is needed in Colombia with more representative samples to establish a starting point for improving the lives of women who delay motherhood until after age 35. It is also essential to expand understanding of the work reentry process, with qualitative studies examining the experiences and perceptions of mothers over 35.
