Employment, income, and education and prevalence of depressive symptoms during pregnancy: the Kyushu Okinawa Maternal and Child Health Study

Depressive symptoms during pregnancy and postpartum: associations with mode of conception and demographic and obstetric factors

An increasing number of women are conceiving through assisted reproductive technology; however, few studies have investigated their mental health after successful conception. This study investigated the changes in depressive symptoms in women using assisted reproductive technology and the association between the mode of conception and perinatal depressive symptoms. A longitudinal observational study was conducted from 2015 to 2019, 542 pregnant women completed questionnaires on depressive symptoms at eight timepoints during the prepregnancy, pregnancy and first-year postpartum periods. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. A generalized estimating equation regression model was employed for repeated measures. In the assisted reproductive technology group, depressive symptoms were more prevalent during early pregnancy and at 1 month postpartum than before pregnancy, and more prevalent before pregnancy and at 1 month after childbirth than in the spontaneous conception group. No significant association was identified between the mode of conception and depressive symptoms during the antenatal or postnatal period. The lack of full-time employment and prepregnancy depressive symptoms were associated with antenatal depressive symptoms. Primipara status and depressive symptoms during prepregnancy and pregnancy were associated with depressive symptoms during the first-year postpartum. Assisted reproductive technology was not a risk factor for depressive symptoms during the pregnancy and postpartum periods, whereas primipara status, lack of full-time employment and prepregnancy depressive symptoms were negative predictors. Therefore, targeted mental health interventions should address these specific factors to effectively support maternal mental health.

Challenges, experiences, and potential supports for East and Southeast Asian mothers in the workforce: a systematic review

OBJECTIVE

To examine the challenges faced by Asian working mothers with a focus on re-entry to the workplace. In addition, we highlight potential supports that retain women in the workforce.

DESIGN

A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations and registered with PROSPERO database (CRD42022341130).

METHODS

Three independent reviewers were involved in the study selection to screen the search results sequentially by title, abstract, and full text using predefined inclusion and exclusion criteria. The methodological quality of each article was assessed via the Critical Appraisal Skills Programme (CASP) tool.

RESULTS

We analysed a total of 36 studies conducted across different regions: 30 from the East and 6 from Southeast Asia. Among these studies, 20 were quantitative in nature, 15 were qualitative, and one intervention. The 36 studies cover five themes: 1) policies, 2) external support sources, 3) external pressure, 4) breastfeeding and 5) health status. Within each theme the same factor can have a positive or negative impact on the mother depending on her having a pro-career or pro-family mindset. Companies can take various initiatives to support working mothers, such as providing facilities for expressing breast milk at the workplace, educating staff to promote breastfeeding and accommodate childcare needs, and extending maternity leaves. However, there is a lack of literature that directly addresses the barriers and concrete support available to working mothers in Asia, beyond the scope of breastfeeding.

CONCLUSIONS

Our findings underscore several obstacles that can impede a woman's seamless return to work. Pro-family and pro-career mothers have differing needs that cannot be addressed at the same time. There is a lack of comprehensive understanding regarding effective strategies or interventions that can support a positive reintegration into the workforce.

Relationship of depression and sleep quality, diseases and general characteristics

BACKGROUND

Depression is the most common type of depressive disorder. The most common sleep disorder associated with depression is insomnia. Insomnia and depression are closely related.

AIM

To investigate the relationship of designed questionnaire items and depression, and analyze the related factors with depression.

METHODS

Questionnaire included Patient Health Questionnaire-9 (PHQ-9) and Pittsburgh sleep quality index (PSQI), 12 kinds of diseases, 8 general characteristics, and 20 insomnia characteristics, totally 56 items were filled out by 411 patients enrolled.

RESULTS

All the 9 items of PHQ-9, 6 components of PSQI (except sleep duration), education, living situation, exercise, years of insomnia, western medicine treatment, Chinese medicine treatment, psychotherapy, kinds of insomnia, treatment expected to treat insomnia, psychological counseling, habit of 1 h before bed, habit of lunch break, diagnosed depression, coronary heart disease, mental illness showed significant difference between without and with depression group. By univariate analysis and multivariate analysis. The odds ratio of education, exercise, kinds of insomnia, habit of 1 h before bed, diagnosed depression, coronary heart disease (P = 0.01) showed significant difference. Their odds ratios were 0.71 (0.55, 0.93), 2.09 (1.32, 3.31), 0.76 (0.63, 0.91), 0.89 (0.81, 0.98), 0.32 (0.17, 0.60), 0.43 (0.23, 0.79).

CONCLUSION

We demonstrated that education, exercise, kinds of insomnia, habit of 1 h before bed, diagnosed depression and coronary heart disease affect the depression.

Prevalence and related factors of perinatal depression in Egyptian mothers

Background

Early detection of perinatal depression and its cultural determinants could reduce its sequalae on mothers and their babies. This study investigated the prevalence of perinatal depression in Egyptian mothers and compare women with and without perinatal depression regarding the psychosocial factors.

Three-hundred one women were recruited (166 were pregnant and 135 were in postpartum period) from a primary healthcare unit. Full sociodemographic data, Social Classification Scale, Dyadic Adjustment Scale (DAS), and the Edinburgh Postnatal Depression Scale (EPDS) were completed. Subjects with EPDS score > 9 answered the structured clinical interview (SCID-I) for diagnosis of depression and Hamilton Rating Scale for Depression (HRSD) for depression severity.

Results

Depression with mild to moderate severity was reported in 5.4% and 3.7% of women during pregnancy and postpartum period, respectively. There was a statistically significant association between depression and employment (p = 0.031), mother-in-law disputes (p = 0.002), stigma of being the second wife (p = 0.047), and having financial burdens (p = 0.001). Marital satisfaction was a protective factor for depression (p < 0.001).

Conclusions

Prevalence of perinatal depression was comparable to other developing countries. It was strongly linked to culturally related factors including marital women’s employment, mother-in-law disputes, being the second wife, and socioeconomic burdens. Early detection of perinatal depression and its culturally related factors is important for its management.

Associations of job type, income, and education with postpartum depressive symptoms: The Kyushu Okinawa Maternal and Child Health Study

Epidemiological evidence on the role of socioeconomic status on postpartum depressive symptoms has been inconsistent. The present prospective study investigated the relationship between employment, job type, income, and education and postpartum depressive symptoms. Subjects were 1316 Japanese women. The subjects were asked to complete an Edinburgh Postnatal Depression Scale (EPDS) between three and four months postpartum. Postpartum depressive symptoms were defined as EPDS score ≥ 9. The prevalence of postpartum depressive symptoms was 8.2%. Compared with unemployment, holding a sales job was independently related to a reduced risk of postpartum depressive symptoms: the adjusted odds ratio (OR) was 0.13 (95% CI: 0.01-0.66). Compared with a household income under four million yen per year, a household income of six million yen or more per year was independently inversely associated with postpartum depressive symptoms: the adjusted OR was 0.33 (95% CI: 0.16-0.63). Compared with less than 13 years of education, both 13 or 14 years and 15 years or more were independently inversely related to postpartum depressive symptoms: the adjusted ORs were 0.40 (95% CI: 0.23-0.69) and 0.48 (95% CI: 0.28-0.82), respectively. Holding a sales job, higher household income and higher educational levels may be inversely associated with postpartum depressive symptoms.

Association of secondhand smoke and depressive symptoms in nonsmoking pregnant Women: A systematic review and meta-analysis

BACKGROUND

Globally about 30% of adult women and 40% of children are exposed to secondhand smoke (SHS) from active smokers. SHS exposure of pregnant women has been associated with postpartum depression. Unexposed women in pregnancy had lower rates of postpartum depression than women exposed to SHS. This systematic review aimed to determine the association of depressive symptoms and exposure to SHS in nonsmoking pregnant women.

METHOD

The case-controlled, cross-sectional, and cohort studies with a comparison group were included. Studies including women who had smoking history during pregnancy were excluded. The comprehensive electronic databases, CINAHL, EMBASE, and Medline were searched.

RESULT

Of the 2777 records screened, seven studies were included in the review for data extraction. The bias of studies was assessed using the RoBANS. We synthesized two studies that showed depressive symptoms at any time during pregnancy and postpartum significantly increased (ORs = 1.77 [95% CI = 1.12 - 2.79]; p = 0.01; I²= 28%, 4103 women, two studies), and significantly increased the odds of antenatal suicidal ideation in SHS exposed women (ORs = 1.75 [95% CI = 1.14 - 2.70]; p = 0.01; I²= 51%, 2670 women, two studies). Lack of studies from counties with the highest smoking rates was a limitation.

CONCLUSIONS

SHS exposure during pregnancy showed a significant increase in the odds of depressive symptoms. Furthermore, research is required to clarify to association between SHS and depression.

Human and economic resources for empowerment and pregnancy-related mental health in the Arab Middle East: a systematic review

This systematic review synthesizes research on the influence of human and economic resources for women's empowerment on their pre- and postnatal mental health, understudied in the Arab world. We include articles using quantitative methods from PubMed and Web of Science. Two researchers reviewed databases and selected articles, double reviewing 5% of articles designated for inclusion. Twenty-four articles met inclusion criteria. All 24 articles measured depression as an outcome, and three included additional mental health outcomes. Nine of 17 studies found an inverse association between education and depression; two of 12 studies found contradictory associations between employment and depression, and four of six studies found a positive association between financial stress and depression. These results suggest that there is a negative association between education and depression and a positive association between financial stress and depression among women in the Arab world. Firm conclusions warrant caution due to limited studies meeting inclusion criteria and large heterogeneity in mental health scales used, assessment measures, and definitions of human and economic resources for women's empowerment. It is likely that education reduces depression among postpartum women and that financial stress increases their depression. These findings can be used to aid in the design of interventions to improve mother and child outcomes. However, more research in the Arab world is needed on the relationship between human and economic resources for women's empowerment and perinatal mental health, and more consistency is needed in how resources and mental health are measured.

Association of household income and education with prevalence of hearing impairment in Japan

OBJECTIVES/HYPOTHESIS

Epidemiological information regarding the relationship between household income and education and hearing impairment (HI) is limited. The present cross-sectional study investigated this issue in Japan.

STUDY DESIGN

Cross-sectional investigation.

METHODS

Study subjects were 371 men and 639 women aged 36 to 84 years. A self-administered questionnaire was used. Audiological assessment was performed by pure-tone audiometry. HI was defined as present in subjects who did not respond to a pure-tone average of >25 dB HL in the better hearing ear according to the World Health Organization standard. Adjustment was made for age, smoking status, alcohol consumption, hypertension, dyslipidemia, diabetes mellitus, and body mass index.

RESULTS

The prevalence of HI was 31.5% in 371 men and 20.8% in 639 women. In men, a slight inverted J-shaped association was observed between household income and HI, compared with a household income of <3 million yen per year. A household income of 3 to 5 million yen, but not of 5 million yen or more, was independently inversely associated with the prevalence of HI; the prevalence ratio for 3 to 5million yen was 0.73 (95% confidence interval: 0.54-0.999). After adjustment for confounding factors, no relationship was found between household income and the prevalence of HI in women. There were no associations between educational level and the prevalence of HI in either men or women in the multivariate model.

CONCLUSIONS

Our results suggest that medium, but not high, household income may be associated with a lower prevalence of HI only in men.

Changes in the Relationship Between Socioeconomic Position and Maternal Depressive Symptoms: Results from the Panel Study on Korean Children (PSKC)

Maternal depression is a common health problem during the perinatal period. The purpose of this study was to examine changes in the relationship between socioeconomic position and maternal depressive symptoms from prenatal to 3 years postpartum in Korean women. Prospective cohort data were collected from the Panel Study on Korean Children between 2008 and 2011. Maternal depression was assessed using the Kessler 6-Item Psychological Distress Scale. Socioeconomic position indicators used were maternal education, paternal education, maternal occupation, paternal occupation, and household income. Repeated-measures analyses with a generalized estimating equation approach were used to investigate relationships between socioeconomic position and maternal depressive symptoms during the study period. Low socioeconomic position was associated with greater levels of maternal depressive symptoms between 4 months after childbirth and 3 years postpartum, but the association was not evident between 1 month before and after childbirth. The magnitude of the significant association between socioeconomic position and maternal depression was the greatest at 1 year postpartum but then became smaller. Among the five socioeconomic position indicators included, maternal education, paternal education, and household income showed graded inverse relationships with maternal depressive symptoms, while no significant relationship was found for paternal occupation over the study period. Socioeconomic inequalities in maternal depressive symptoms emerged in early childhood in a prospective study of Korean mothers. These emerging inequalities may contribute to socioeconomic inequalities in childhood health and development.

Immediate effects of the Fukushima nuclear power plant disaster on depressive symptoms among mothers with infants: a prefectural-wide cross-sectional study from the Fukushima Health Management Survey

BACKGROUND

Mothers of young children are at high-risk for developing adverse mental health effects following a nuclear accident. Using the Japanese pregnancy registration system, the prefecture of Fukushima launched a population-based survey of women who were pregnant at the time of the Fukushima nuclear accident in order to assess their and their newborns' health. In this paper, we focus on the results of a screen for depressive symptoms among new mothers and its association with geographical region and interruption of obstetrical care after the Fukushima nuclear accident, which occurred after the Great East Japan Earthquake on March 11, 2011.

METHODS

The survey targeted women who lived in Fukushima prefecture and who had registered their pregnancies between August 1, 2010 and July 31, 2011. Among the 16,001 women targeted, 9,321 returned the questionnaires (response proportion = 58.3%) and data from 8,196 women with singleton live births were analyzed. The main outcome measure was a standard two-item depression screen. Regional radiation levels were determined from the prefecture's periodical reports, and interruption in obstetrical care after the Fukushima nuclear accident was determined from mothers' individual responses to the questionnaire.

RESULTS

Among the 8,196 women, 2,262 (28%) screened positive for depressive symptoms. After adjusting for maternal and infant characteristics, both mothers in Soso, the region in which the nuclear power plant is located, and mothers that had changed obstetrical care facilities were significantly more likely to screen positive for depression. In contrast, mothers in Iwaki and Aizu, regions with relatively low radiation levels, were significantly less likely to screen positive for depression.

CONCLUSIONS

Our findings suggest that improving mental health support for mothers with infants should be a high priority in the acute phase of nuclear disaster response. We further recommend that in the strategic provisioning of parental support, close attention should be paid to regional variations in negative mental health consequences, particularly to those who experienced an interruption in their obstetrical care.

The use of the edinburgh postpartum depression scale in a population of teenager pregnant women in Mexico: a validation study

Background

:Depression may occur in teenager pregnant women. The use of a validated tool for screening depression is highly recommended. The Edinburgh postnatal depression scale (EPDS) is a screening tool for depression used in women during the postnatal period and pregnancy. However, the EPDS has not been validated in teenager pregnant women. Therefore, we sought to validate a Spanish translated Mexican version of the EPDS in a population of teenager pregnant women. Methods: One hundred and twenty teenager pregnant women attending routine prenatal consultations in a public hospital in Durango City, Mexico participated in the study. All participants submitted a revised Spanish translated Mexican version of the EPDS and were examined by a psychiatrist to evaluate the presence of depression by using DSM-IV criteria. Results: Of the 120 teenager pregnant women studied, 2 had major depression and 25 had minor depression according to the DSM-IV criteria. The optimal EPDS cut-off for screening combined major and minor depression in teenager pregnant women was 8/9. At this threshold, we found a sensitivity of 70.4%, a specificity of 84.9%, a positive predictive value of 47.6%, a negative predictive value of 91.0%, and an area under the curve of 0.81 (95% confidence interval: 0.56-1.07). Conclusion: The EPDS can be used for screening depression in Mexican teenager pregnant women whenever a cut-off score of 8/9 is used.

Use of antidepressants and association with elective termination of pregnancy: population based case-control study

OBJECTIVE

To assess whether the use of selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants, mirtazapine, venlafaxine or other antidepressants is associated with late elective termination of pregnancy.

DESIGN

Case-control study using data from national registers.

SETTING

Denmark, Finland, and Norway during the period 1996-2007.

POPULATION

A total of 14,902 women were included as cases and 148,929 women were included as controls.

METHODS

Cases were women with elective termination of pregnancy at 12-23 weeks of gestation. Controls continued their pregnancy and were matched with cases on key factors.

MAIN OUTCOME MEASURES

Association between antidepressant use during pregnancy and elective termination of pregnancy at 12-23 weeks of gestation for fetal anomalies, or for maternal ill health or socio-economic disadvantage.

RESULTS

At least one prescription of antidepressants was filled by 3.7% of the cases and 2.2% of the controls. Use of any type of antidepressant was associated with elective termination of pregnancy for maternal ill health or socio-economic disadvantage (odds ratio, OR 2.3; 95% confidence interval, 95% CI 2.0-2.5). Elective termination of pregnancy for fetal anomalies was associated with the use of mirtazapine (OR 2.2, 95% CI 1.1-4.5). There was no association between the use of any of the other antidepressants and elective termination of pregnancy for fetal anomalies.

CONCLUSION

The use of any type of antidepressants was associated with elective termination of pregnancy at 12-23 weeks for maternal ill health or socio-economic disadvantage, but not with terminations for fetal anomalies. Further studies need to confirm the findings concerning mirtazapine and termination of pregnancy for fetal anomalies.

Validation of the edinburgh postpartum depression scale in a population of adult pregnant women in Mexico

Background

The Edinburgh postnatal depression scale (EPDS) is useful for screening depression in puerperal women as well as women during pregnancy. However, such instrument should be validated in a given language before it can be used. There is not validated Mexican version of the EPDS for use in adult pregnant women. Therefore, we sought to validate a Spanish translated Mexican version of the EPDS in a population of adult pregnant women.

Methods

One hundred fifty-eight adult women (mean age: 28 ± 6.8 years; range: 18 - 45 years) within their 2 - 9 months of pregnancy attending routine prenatal consultations in a public hospital in Durango City, Mexico were studied. All pregnant women submitted a Spanish translated Mexican version of the EPDS. In addition, participants were assessed for major and minor depression by using the DSM-IV criteria.

Results

Of the 158 pregnant women studied, 11 had major depression and 26 had minor depression by the DSM-IV criteria. The best EPDS score for screening combined major and minor depression in adult pregnant women was 9/10. This threshold showed a sensitivity of 75.7%, a specificity of 74.4%, a positive predictive value of 50.8%, a negative predictive value of 94.7% and an area under the curve of 0.89 (95% confidence interval: 0.71 - 1.06).

Conclusion

The Mexican version of the EPDS can be considered for screening depression in Mexican adult pregnant women whenever a cut-off score of 9/10 is used.

Intake of dairy products and calcium and prevalence of depressive symptoms during pregnancy in Japan: a cross-sectional study

OBJECTIVE

To examine the relationship between the intake of dairy products and calcium and the prevalence of depressive symptoms during pregnancy.

DESIGN

Cross-sectional study.

SETTING

Kyushu Okinawa Maternal and Child Health Study (KOMCHS).

SAMPLE

A cohort of 1745 pregnant Japanese women.

METHODS

Dietary intake during the preceding month was assessed using a self-administered diet history questionnaire. Scores of 16 or higher on the Center for Epidemiologic Studies Depression Scale denoted depressive symptoms. Adjustment was made for age, gestation, region of residence, number of children, family structure, history of depression, family history of depression, smoking, secondhand smoke exposure at home and at work, job type, household income, education, and body mass index. In our analyses regarding dairy products in general, adjustment was also made for fish intake; in our analysis regarding calcium, adjustment was also made for the intake of saturated fatty acids, eicosapentaenoic acid plus docosahexaenoic acid, and vitamin D.

MAIN OUTCOME MEASURES

Depressive symptoms during pregnancy.

RESULTS

Higher intake levels of yogurt and calcium were independently related to a lower prevalence of depressive symptoms during pregnancy: the adjusted odds ratios between extreme quartiles were 0.69 (95% CI 0.48-0.99, P for trend = 0.03) and 0.59 (95% CI 0.40-0.88, P for trend = 0.006), respectively. No relationships were observed between the intake of all dairy products, milk, or cheese and depressive symptoms during pregnancy.

CONCLUSIONS

The current results suggest that a higher intake of yogurt and calcium may be associated with a lower prevalence of depressive symptoms during pregnancy.

Predictors of mental health during pregnancy

BACKGROUND

Pregnancy with anxious or depressive symptoms might be associated with worse birth outcomes. The aim of this study was to determine the demographic predictors of anxiety and depression symptoms in pregnant women.

MATERIALS AND METHODS

We assessed pregnancy anxiety and depression levels among 142 women in three trimesters. All subjects completed two questionnaires: Demographic scale and the 21-item Depression Anxiety Stress Scale (DASS-21) questionnaire. Chi-square test and regression analysis were used to assess the association between anxiety and depression symptoms with maternal age, maternal education, family income, gestational age, body mass index, parity, and pregnancy risk.

RESULTS

25.3% of the pregnant women reported having depressive symptoms. Also, 49.3% of the subjects reported having anxiety symptoms. There was positive correlation between body mass index, gestational age, and pregnancy risk with depression symptom. Also, there was negative correlation between family income and maternal education level with anxiety symptom. In linear regression model, the variables of maternal age, maternal education, parity, abortion, gestational age, family income, body mass index, and pregnancy risk predicted 44.7% anxiety (F = 1.903, P = 0.006) and 68.1% depression (F = 2.101, P = 0.003). The strongest predictors of depression in pregnant women were pregnancy risk (β = 0.361, P = 0.001) and maternal education (β = -0.297, P = 0.006). Also, pregnancy risk (β = 0.523, P = 0.001) and gestational age (β = 0.477, P = 0.01) were the important predictors of maternal anxiety in the pregnancy period.

CONCLUSIONS

Pregnancy risk, gestational age, and education level are the strongest predictors of mental health in the pregnancy period. This result suggests that psychological support is needed for pregnant women with high risk and low education, especially in the third trimester, to improve their mental health.
