Abstract

Background

While it is recognized that social support can alleviate mental health symptoms, this relationship is not well-understood among Chinese pregnant and parenting immigrants in the United States. This study aims to bridge this gap by exploring the relationships between different types of social support and women’s anxiety and depression, and examining how these associations vary with pregnancy status.

Methods

Data were obtained from a cross-sectional survey conducted in Simplified Chinese or Mandarin between March-June 2021 among 526 women who were pregnant and/or parenting a child under five years. The Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety, Depression, and Social Support scales were used to measure anxiety, depression, and social support levels. Descriptive statistics, t-tests, chi-square tests, and Pearson’s correlations were employed for analysis. Hierarchical regression was conducted to investigate the main and interaction effects of social support types and pregnancy status on mental health outcomes.

Results

Compared to non-pregnant women, pregnant women reported higher mean scores for anxiety (non-pregnant: 55, pregnant: 59, p < 0.01) and depression (non-pregnant: 54, pregnant: 56, p = 0.02). Instrumental support displayed a significant main effect in relation to anxiety (β=-0.13, p = 0.01) and depression (β=-0.16, p < 0.01); emotional support exhibited a significant main effect solely on depression (β=-0.13, p = 0.01). Notably, the interaction effects between pregnancy status and both instrumental (β=-0.28, p = 0.01) and emotional support (β=-0.42, p < 0.01) were significant for anxiety. In contrast, informational support did not exhibit a significant impact on either anxiety or depression.

Conclusions

The findings indicate that tailoring support to the cultural context is crucial, especially for pregnant women in this Chinese immigrant community, with instrumental and emotional support being particularly beneficial in mitigating maternal anxiety.

Peer Review reports

Background

Pregnant and parenting women represent a vulnerable group at elevated risk of experiencing adverse mental health outcomes [1,2,3]. Extensive research consistently highlights the prevalence of mental health concerns during the pregnancy and postpartum periods [4,5,6]. These critical phases are characterized by significant physical, emotional, and social changes, contributing to heightened mental health concerns [7,8,9,10]. Additionally, postpartum depressive symptoms can impact children’s neurodevelopment and overall health [11,12,13,14], and such symptoms and effects can last beyond the initial year after childbirth [15,16,17].

Chinese immigrants constitute one of the largest immigrant groups in the United States (U.S.) [18]. Underserved Chinese immigrant women in the U.S. encounter multiple challenges, including language barriers, economic instability, and social isolation [19,20,21], a significant risk factor for depression [22, 23]. The coronavirus disease 2019 (COVID-19) pandemic has further heightened mental health concerns for these women, due to stress and anxiety over health and economic uncertainties [24]. Research has demonstrated that Chinese immigrant mothers with young children exhibit higher levels of depressive symptoms compared to non-immigrant mothers [25]. However, limited research has specifically examined the mental health challenges of Chinese immigrant pregnant women in the United States.

The significant impact of culturally-relevant social support on mental health outcomes among immigrant populations has been consistently underscored in research [26,27,28,29]. Social support is a multidimensional construct encompassing instrumental support, involving tangible aid; informational support, providing guidance and knowledge; and emotional support, offering empathy and comfort during times of stress [30, 31]. Studies across different countries highlight distinct impacts of different types of social support on mental health outcomes [32,33,34], particularly given women’s distinctive needs for various types of support during pregnancy and different motherhood stages [35,36,37,38]. For Chinese immigrant women, social support has been associated with lower mental health symptoms [39,40,41]. However, the associations between different types of social support and mental health outcomes among Chinese immigrant pregnant women and mothers remains unclear.

The current study

This study will address these gaps and pursue the following aims among a sample of Chinese pregnant women and mothers of young children: (Aim 1) to examine potential differences in levels of anxiety and depression among pregnant women and mothers, (Aim 2) to explore the associations between different types of social support and anxiety and depression, and (Aim 3) to investigate whether these associations vary by pregnancy status. By examining these factors, this study has the potential to inform the development of tailored interventions that address anxiety and depression among underserved Chinese immigrant women.

Method

Study design

This study is part of the “Together Growing Strong” initiative in Sunset Park, Brooklyn, which supports families with young children. While Sunset Park, a vibrant immigrant community, has tight-knit families, it grapples with issues like worker exploitation, low wages, and overcrowded housing.

Using a mixed-methods approach, we conducted both quantitative surveys and qualitative interviews. Materials were available in English, Spanish, and Chinese (Simplified Chinese and Mandarin) to cater to community preferences. We used a convenience sample to recruit participants from health centers, social service locations, and texting platforms. Furthermore, participants could choose to self-administer the survey online or complete the survey over the phone with a trained interviewer. Ethical approval for this research has been granted by the Institutional Review Board of NYU Grossman School of Medicine (reference number: s20-01944).

Participants

Study participants were women aged 18 years or older and either pregnant or parenting a child under 5 years old. As an incentive, participants received a gift card worth $25 upon survey completion. The current analysis is based on the quantitative data from a subset of participants who completed the survey in Simplified Chinese or Mandarin between March and June 2021. To ensure linguistic and cultural consistency, only participants who completed the survey in Simplified Chinese or Mandarin were included in this analysis (n = 526). Of the 145 women excluded from the analysis, fifteen took the survey in English and identified as Chinese ethnicity, of whom 8 were born outside the U.S.

Measures

Dependent variables: PROMIS anxiety and depression

Participants completed the Patient-Reported Outcomes Measurement Information System® (PROMIS®) Short-Form (SF) v1.0 – Anxiety and the PROMIS SF v1.0 – Depression [42], assessing anxiety and depression symptoms. Both scales used a 5-point Likert scale to rate symptoms over seven days. The Anxiety scale comprised four items, including aspects, such as “I felt fearful” and “I felt uneasy.” The Depression scale also had four items capturing self-reported feelings, such as “I felt worthless” and “I felt hopeless.” Total scores for anxiety and depression were converted to standardized T-scores, with a mean of 50 and a standard deviation of 10, based on a calibration sample from the U.S. general population. Higher T-scores indicated greater levels of anxiety or depression [43,44,45]. Severity levels for anxiety and depression were categorized based on T-scores, with 55-59.9 representing mild symptoms, 60-69.9 representing moderate symptoms, and ≥ 70 representing severe symptoms [46]. Previous research has demonstrated sufficient linguistic equivalence and cross-cultural validity of the Chinese version of the PROMIS SF [47,48,49].

Independent variable

PROMIS social support

To assess social support, the PROMIS Short Form v2.0 Informational, Instrumental, and Emotional Support scales were utilized [42]. These scales measure different dimensions of social support, with statements such as “I have someone to give me good advice about a crisis if I need it.” (informational support), “Do you have someone to help you if you are confined to bed?” (instrumental support), and “I have someone who will listen to me when I need to talk.” (emotional support). Participants responded to each item using a five-point Likert scale, with response options ranging from 1 (never) to 5 (always). Total scores for each dimension of social support were converted to standardized T-scores, with a mean of 50 and a standard deviation of 10, based on a calibration sample from the U.S. general population. Higher T-scores indicated greater levels of support [43, 45]. The PROMIS Social Support scales have been translated and psychometrically validated in Chinese [49, 50].

Pregnancy status

Pregnancy status was based on the response to the question “Are you currently pregnant?” Women were categorized as “pregnant” if they were currently pregnant regardless of whether they also had other children. Women were categorized as “not pregnant” if they were not currently pregnant and had at least one child aged less than five years.

Control variables

Covariate selection involved two steps. First, we identified potential covariates through a literature review of factors relevant to mental health and social support among immigrant populations. These included age, marital status, financial difficulties, general health status, education level, language spoken, and years living in the U.S. [51,52,53,54,55,56]. Second, to ensure model parsimony while accounting for relevant factors, we conducted bivariate analyses to determine significant associations with our outcomes and independent variables (Supporting Table 1). Covariates showing significant associations (p ≤ 0.05) in bivariate analyses were included in the multivariable models. These were: age (18–29 vs. 30 or above), marital status (single, divorced, widowed vs. married or living with a partner), having difficulties paying bills (no difficulty at all vs. any level of difficulty), and general health (poor or fair vs. good, very good or excellent). Education level, language spoken at home, and years living in the U.S. did not show significant associations with our primary outcomes or independent variables and were therefore not included in the final models.

Statistical analysis

First, descriptive statistics were used to calculate the frequencies and mean scores for all analyzed variables. t-tests and Chi-Square tests were also used to examine differences between pregnant and non-pregnant women regarding the study variables, anxiety and depression (Aim 1).

Second, t-tests were conducted to examine differences in anxiety and depression scores across levels of socio-demographic and health-related variables. Pearson’s correlations were run to investigate associations among three types of social support, anxiety, and depression to understand the underlying associations among continuous variables (i.e. informational support, instrumental support, emotional support, anxiety, and depression) and to test for collinearity.

Third, hierarchical regression was performed to examine the main and interaction effects of each type of social support and pregnancy status in relation to anxiety and depression scores. For each outcome, three models were constructed to explore the associations between different types of social support and mental health outcomes (Aim 2), including Model 1 (instrumental support), Model 2 (emotional support), and Model 3 (informational support). In each model, Step 1 included the control variables, pregnancy status, and the corresponding type of support. In Step 2, the interaction term between pregnancy status and the corresponding support was added to the model to examine whether the associations vary by pregnancy status (Aim 3). To reduce multicollinearity between the main effects and interactions, we mean-centered the continuous independent variables (i.e. informational support, instrumental support, and emotional support). The variance inflation factor values and condition index were examined and no multicollinearity was found.

To address multiple comparisons, we applied the Benjamini-Hochberg procedure to control the false discovery rate (FDR) for each outcome separately across the three models. Both original and FDR-adjusted p-values are reported, with statistical significance determined based on adjusted p-values (p ≤ 0.05). Finally, to interpret the significant two-way interactions in the regression models, simple slope analyses were conducted. Missing data within the utilized variables ranged from 3 to 10%, and all such cases with missing data were excluded from the analysis.

Results

General descriptive statistics and pregnancy differences

Table 1 shows the socio-demographic characteristics for the total sample (n = 526) and by pregnancy status (n = 100 pregnant; n = 426 non-pregnant). Among the total sample, the majority were aged 30 and above (72%) and married or living with a partner (90%), and experienced difficulties paying bills (73%). Over half had completed at least a high school degree (57%). Of those not born in the U.S. (n = 423), 58% had lived in the U.S. for less than 10 years. Only 7% of the total sample reported speaking English at home. Although the pregnant and non-pregnant groups were similar in terms of education, marital status, economic difficulties, and immigration-related factors, they differed significantly in age. A lower percentage of pregnant women (59%) were aged 30 and above than the non-pregnant group (75%) (p < 0.01).

Table 1 Descriptive characteristics for the full sample and by pregnancy status
Full size table

The majority of the sample (86%) reported their health as good, very good or excellent. The mean scores for informational, instrumental, and emotional support were 43, 47, and 44, respectively. Overall, the mean anxiety score was 56, with 37% of women having a score at or above 60, indicating moderate to severe anxiety. Overall, the mean depression score was 54, with 31% of women having a score at or above 60, indicating moderate to severe depression. No significant differences were observed between pregnant and non-pregnant groups across general health and mean levels of support. However, compared to non-pregnant women, pregnant women reported higher mean scores for anxiety (non-pregnant: 55, pregnant: 59, p < 0.01) and depression (non-pregnant: 54, pregnant: 56, p = 0.02).

Correlations between support, anxiety, and depression

Moderate to strong positive correlations were found between informational and emotional support (r = 0.78, p < 0.01), informational and instrumental support (r = 0.53, p < 0.01), and instrumental and emotional support (r = 0.58, p < 0.01). In addition, instrumental support and emotional support were negatively correlated with anxiety (instrumental: r=-0.19, p < 0.01; emotional: r=-0.24, p < 0.01) and depression (instrumental: r=-0.13, p < 0.001; emotional: r=-0.18, p < 0.01). No significant relationship was found between informational support and anxiety (r=-0.05, p = 0.28) or depression (r=-0.08, p = 0.08).

Effect of social support and pregnancy status on anxiety and depression

Anxiety

Table 2 presents the regression analysis results for the associations between pregnancy status and social support, and anxiety. To account for multiple comparisons, both unadjusted and Benjamini-Hochberg adjusted p-values are reported. Statistical significance was determined based on the adjusted p-values, with p ≤ 0.05 considered significant. The majority of our findings remained statistically significant after this adjustment, enhancing the reliability of our results while maintaining sensitivity to potentially important relationships in this exploratory study. As seen in Model 1 (N = 406), Step 1 indicated that the main effects of instrumental support and pregnancy status were significantly related to anxiety (instrumental support: β=-0.13, p = 0.01, adjusted p = 0.02; pregnancy status: β = 2.19, p = 0.02, adjusted p = 0.03). Step 2 revealed a significant interaction effect between instrumental support and pregnancy status regarding anxiety (instrumental support X pregnancy: β=-0.28, p = 0.01, adjusted p = 0.02). The analysis conducted in Model 2 (N = 405), Step 1 found a statistically significant effect of pregnancy status (β = 2.15, p = 0.03, adjusted p = 0.05), but emotional support was not statistically related to anxiety (β=-0.07, p = 0.18, adjusted p = 0.22). Nevertheless, adding the interaction terms between emotional support and pregnancy status in Step 2 revealed a significant interaction effect on anxiety (emotional support X pregnancy: β=-0.42, p < 0.01, adjusted p < 0.01). In Model 3 (N = 403), focusing on informational support as the main independent variable, Step 1 results mirrored the findings of the bivariate analysis, indicating no significant association between informational support and anxiety (β = 0.02, p = 0.67, adjusted p = 0.67); in Step 2, no significant interaction effect was observed for anxiety (informational support X pregnancy: β=-0.14, p = 0.30, adjusted p = 0.42) (see Supporting Table 2).

Post hoc simple slope analyses were conducted for the significant interactions. Figure 1a depicts that higher levels of instrumental support were associated with lower levels of anxiety in the non-pregnant group (β=-0.07), but this relationship was stronger in the pregnant group (β=-0.35) (marginal difference = 0.28, p = 0.01). Figure 1b shows an even starker difference in the association between emotional support and anxiety, between the pregnant and non-pregnant groups, with a marginal difference of 0.42 (p < 0.01).

Depression

Table 3 displays the regression analysis results exploring the impact of pregnancy status and social support on depression. In contrast to the anxiety models, the hierarchical regression results suggested the main effect of pregnancy status was not significant in any of the three models.

Table 3 Multivariable analysis: examining Depression as an outcome
Full size table

In Depression Models 1 (N = 405) and 2 (N = 405), instrumental support (β=-0.16, p < 0.01, adjusted p < 0.01) and emotional support (β=-0.13, p = 0.01, adjusted p = 0.02) were statistically significantly related to depression. No significant interaction effects were found between any type of support and pregnancy status when considering depression, suggesting that the effect of support on depression does not differ by pregnancy status. Consistent with the results from the bivariate analysis, no significant influence of informational support on depression was found (see Supporting Table 3).

Discussion and conclusion

Mental health challenges

This study reveals that low-income Chinese immigrant mothers endorsed a range of mental health challenges, as evidenced by the survey results indicating a substantial prevalence of moderate to severe anxiety and depression among Chinese immigrant pregnant women and mothers of young children. These findings align with prior research highlighting the heightened risk of anxiety and depression during pregnancy among Chinese women [57, 58].

Further, while regression analyses indicated that pregnancy status did not have a significant effect on depression scores, pregnancy status was a significant independent variable for anxiety models even when controlling for social support. This indicates the unique contribution of pregnancy to heightened anxiety levels among Chinese immigrant women. The COVID-19 pandemic may have exacerbated perinatal mental health challenges, particularly in immigrant communities [59]. It is crucial to identify and implement strategies, including enhancing social support, to alleviate maternal mental challenges, particularly addressing perinatal anxiety.

The importance of support in mitigating mental health symptoms: cultural specificity, immigration factors, and pregnancy status

Our findings underscore the importance of support in mitigating mental health symptoms and highlight the nuanced roles of different types of support. Specifically, instrumental support exhibited a significant main effect on both anxiety and depression; emotional support demonstrated a significant main effect exclusively on depression, whereas informational support did not manifest any significant influence. Notably, the relationships between support types and anxiety/depression might be culturally specific to our study’s group of Chinese predominantly immigrant mothers. In East Asian cultural contexts, tangible/instrumental support providing practical resources has been shown to be prioritized [60]. Similar to our findings, Chen et al.‘s [39]. study in China suggested increased instrumental/emotional support was significantly associated with reduced postpartum depression over time, with informational support lacking significance. However, studies involving women from diverse cultural backgrounds, including Turkish [61], Australian [33], Jordanian [62], and American [38], populations, produced mixed results, underscoring the potential cultural specificity in the relationships between support types and women’s mental health conditions.

The immigration experience of our participants likely plays a crucial role in shaping the relationships between social support and mental health outcomes. Given that a substantial proportion of our sample reported not speaking English at home it is important to consider how these sociolinguistic factors might influence our findings. Recent immigrants often face challenges in accessing and utilizing social support due to limited social networks, unfamiliarity with local systems, and language barriers [63, 64]. These factors may explain the strong association we found between instrumental support and mental health outcomes, as tangible assistance becomes particularly crucial for those navigating a new environment and healthcare system, especially during pregnancy and early motherhood [65]. Language barriers can limit access to and comprehension of health information, potentially reducing the effectiveness of informational support [64, 66], which aligns with our finding of non-significant effects for this type of support. Furthermore, the immigration experience may amplify the importance of emotional support in combating feelings of isolation and maintaining mental health [67], consistent with our observed association between emotional support and depression outcomes. These findings underscore the need for culturally sensitive and language-appropriate support interventions for Chinese immigrant mothers. Future research should explicitly examine how acculturation levels, length of residency, and language proficiency moderate the relationships between different types of social support and mental health outcomes in this population.

In addition, the relationships between support and women’s mental health may vary depending on pregnancy status. Limited research examines the intricate dynamics among various forms of support, pregnancy status, and mental health. To address this gap, our study investigated the interaction effect of different support types and pregnancy on women’s mental well-being. Notably, our findings showed an even greater association between instrumental and emotional support and lower anxiety symptoms among pregnant women, compared to non-pregnant women.

Our study used general measures of anxiety and depression (PROMIS scales) to allow comparison between pregnant and non-pregnant participants, including those past the postpartum period. Pregnancy- and postpartum-specific measures might capture perinatal anxiety and depression more accurately; however, recent research has demonstrated strong correlations between general measures like PROMIS and pregnancy-specific measures, suggesting that general scales can capture mental health aspects relevant to pregnancy [68]. We explored the relationships between these general measures and the perinatal-specific Edinburgh Postnatal Depression Scale (EPDS) in our sample among pregnant participants. Consistent with prior findings, our preliminary analysis suggests there may be strong positive correlations between PROMIS Anxiety T-scores and EPDS scores as well as between PROMIS Depression T-scores and EPDS scores, particularly among the pregnant and postpartum women in our study. Nevertheless, we acknowledge that pregnancy-specific measures might capture additional nuances of perinatal mental health. Scales such as the EPDS could provide insights into pregnancy-specific concerns that may interact differently with various types of social support. For instance, informational support might be particularly beneficial in alleviating pregnancy-specific anxieties about childbirth or infant care, even if it shows less association with general anxiety symptoms in our current findings. Future research employing both general and pregnancy-specific measures could elucidate how different types of social support might differentially impact general versus pregnancy-specific mental health outcomes in this population.

Tailoring support to the cultural context: considering the type and implementation of support

Our findings emphasize the need to customize the type and implementation of support to align with cultural context. Traditional Chinese pregnancy practices involve dietary and activity constraints, especially avoiding cold foods and water [69, 70], suggesting potential benefits of instrumental support, such as meal preparation. Additionally, cultural differences influence how women seek support from various providers based on their relationship; a focus on emotional support within existing social relationships may be accepted in Asian cultures [71, 72], while accepting informational assistance about personal issues may be less favored [73]. Our study demonstrated how specific types of social support can differentially buffer against anxiety and depression among immigrant Chinese women. However, limited research has explored the effective implementation of different support types within cultural context and immigration-related factors. To take into account cultural sensitivity and individual preferences, future studies should investigate the relationship between the various providers of social support and Chinese immigrant women to explore effective implementation strategies.

Conclusions

Our study has several limitations. Firstly, the cross-sectional design limits our ability to examine the temporal dynamics of these associations and determine the directionality of the relationships. Secondly, data collection took place during the COVID-19 pandemic, which may have introduced additional barriers to social support for the participants. Future studies should consider investigating the long-term effects of the pandemic on the mental health of immigrant mothers and its interaction with social support dynamics. Thirdly, the use of self-reported measures in our study introduces the possibility of response bias, and the scales used may not fully capture all the types of support desired by the participants, such as spiritual support. Additionally, the use of general rather than pregnancy-specific mental health measures may have limited our ability to capture some unique aspects of perinatal mental health in our pregnant participants. Future studies on pregnant and postpartum populations could benefit from incorporating pregnancy-specific measures, as they might capture a more nuanced understanding of mental health symptoms in this population.

This study highlighted the mental health challenges faced by low-income Chinese immigrant pregnant women and mothers, with pregnant women experiencing significantly higher levels of anxiety and depression. Social support, particularly instrumental and emotional support, played a crucial role in mitigating women’s anxiety and depression symptoms. Pregnancy status can influence the relationships between support types and mental health outcomes. Tailored interventions considering the specific support needs of pregnant women and mothers of young children can help address mental health concerns in the Chinese immigrant community. Further research should examine the appropriate implementation of each type of support and identify strategies to provide specific support among Chinese immigrant women.
