RESUMO

BACKGROUND: Dysregulation of the immune system has been associated with psychiatric disorders and pregnancy-related complications, such as perinatal depression. However, the immune characteristics specific to perinatal anxiety remain poorly understood. In this study, our goal was to examine specific immune characteristics related to prenatal anxiety within the context of a randomized controlled trial designed to alleviate anxiety symptoms-the Happy Mother - Healthy Baby (HMHB) study in Rawalpindi, Pakistan. MATERIALS AND METHODS: Pregnant women (n = 117) were followed prospectively in the 1st, 2nd, and 3rd trimesters (T1, T2, T3) and at 6 weeks postpartum (PP6). Each visit included a blood draw and anxiety evaluation (as measured by the anxiety subscale of the Hospital Anxiety and Depression Scale - HADS -using a cutoff ≥ 8). We enrolled both healthy controls and participants with anxiety alone; those with concurrent depression were excluded. RESULTS: K-means cluster analysis revealed three anxiety clusters: Non-Anxiety, High and Consistent Anxiety, and Decreasing Anxiety. Principal components analysis revealed two distinct clusters of cytokine and chemokine activity. Women within the High and Consistent Anxiety group had significantly elevated chemokine activity across pregnancy (in trimester 1 (ß = 0.364, SE = 0.178, t = 2.040, p = 0.043), in trimester 2 (ß = 0.332, SE = 0.164, t = 2.020, p = 0.045), and trimester 3 (ß = 0.370, SE = 0.179, t = 2.070, p = 0.040) compared to Non-Anxiety group. Elevated chemokine activity was associated with low birthweight (LBW) and small for gestational age (SGA). CONCLUSION: Our findings reveal a unique pattern of immune dysregulation in pregnant women with anxiety in a Pakistani population and offer preliminary evidence that immune dysregulation associated with antenatal anxiety may be associated with birth outcomes. The dysregulation in this population is distinct from that in our other studies, indicating that population-level factors other than anxiety may play a substantial role in the differences found.

RESUMO

Diet quality has been associated with mental health, and recently, there has been growing interest in the association between sustainability of diets and human health. The objective of this cross-sectional study was to explore the relationship between a newly developed dietary index for health and sustainability, and psychological disorders among Iranian women. Participants in this cross-sectional study included 479 women living in Tehran with no history of chronic disease. A validated 168-item food frequency questionnaire was used to assess dietary intake. The World Index for Sustainability and Health (WISH) was calculated, consisting of four sub-scores: less healthy, healthy, low environmental impact, and high environmental impact. Participants psychological status was assessed using the Depression Anxiety Stress Scale-21. Logistic regression models were used to examine the association between WISH and psychological disorders. Participant ages ranged from 20-50 years, with a mean age of 31.86 (SD:7.68) years. After adjusting for potential confounders (age, energy, BMI, marital status, education, family history of chronic disease, body satisfaction, socio-economic status, physical activity, smoking), women in the highest tertile of the healthy sub-score had significantly lower odds of experiencing depression (OR: 0.40; 95% CI: 0.24-0.67), anxiety (OR: 0.45; 95% CI: 0.23-0.87) and psychological distress (OR: 0.46; 95% CI: 0.28-0.77) compared to the reference group. Similarly, the less healthy sub-score was significantly associated with depression (OR: 0.51; 95% CI: 0.32-0.89), anxiety (OR: 0.44; 95% CI: 0.25-0.78), and psychological distress (OR: 0.57; 95% CI: 0.36-0.90). An inverse association was observed between the low environmental impact sub-score and depression (OR: 0.32; 95% CI: 0.19-0.54), anxiety (OR: 0.38; 95% CI: 0.18-0.76), and psychological distress (OR: 0.30; 95% CI: 0.17-0.51). However, no further significant associations were found with the high environmental impact sub-score, except with depression (OR: 0.57; 95% CI: 0.33-0.96). The healthy and low environmental impact sub-scores of the WISH were found to be inversely associated with depression, anxiety, and psychological distress. However, due to the cross-sectional study design, causality cannot be inferred. Further prospective studies are required to validate and expand upon these findings and explore potential mechanisms and alternative explanations, such as reverse causation. While this study suggests that choosing a diet that is both healthy for individuals and sustainable for the environment may be associated with lower risk of mental health issues among women, more research is needed.

RESUMO

BACKGROUND: COVID-19 is a pandemic caused by nCoV-2019, a new beta-coronavirus from Wuhan, China, that mainly affects the respiratory system and can be modulated by nutrition. METHODS: This review aims to summarize the current literature on the association between dietary intake and serum levels of micronutrients, malnutrition, and dietary patterns and respiratory infections, including flu, pneumonia, and acute respiratory syndrome, with a focus on COVID-19. We searched for relevant articles in various databases and selected those that met our inclusion criteria. RESULTS: Some studies suggest that dietary patterns, malnutrition, and certain nutrients such as vitamins D, E, A, iron, zinc, selenium, magnesium, omega-3 fatty acids, and fiber may have a significant role in preventing respiratory diseases, alleviating symptoms, and lowering mortality rates. However, the evidence is not consistent and conclusive, and more research is needed to clarify the mechanisms and the optimal doses of these dietary components. The impact of omega-3 and fiber on respiratory diseases has been mainly studied in children and adults, respectively, and few studies have examined the effect of dietary components on COVID-19 prevention, with a greater focus on vitamin D. CONCLUSION: This review highlights the potential of nutrition as a modifiable factor in the prevention and management of respiratory infections and suggests some directions for future research. However, it also acknowledges the limitations of the existing literature, such as the heterogeneity of the study designs, populations, interventions, and outcomes, and the difficulty of isolating the effects of single nutrients from the complex interactions of the whole diet.

RESUMO

Maternal responsiveness, a mother's ability to consistently identify infant cues and then act on them, is critical for healthy child development. A woman's social support and spousal relationship may affect responsiveness to an infant, especially among mothers with anxiety. We assessed how social support and spousal relationship quality is associated with responsiveness among anxious mothers, and if postpartum depression (PPD) moderated these associations. Cross-sectional data were collected from 2019 to 2022 in a public hospital in Pakistan from 701 women at six-weeks postpartum. Eligible women had at least mild anxiety in early- to mid- pregnancy. Linear regression analyses assessed if spousal relationship quality and social support from family and friends were associated with maternal responsiveness, measured using the Maternal Infant Responsiveness Instrument. Interaction terms were used to examine if PPD moderated these associations. Spousal relationship quality (B = 2.49, 95% CI: 1.48, 3.50) and social support (B = 1.07, 95% CI: 0.31, 1.83) were positively related to maternal responsiveness to the infant. Emotional support from a spouse was positively associated with responsiveness (B = 1.08, 95% CI: 0.12, 2.03 depressed; B = 2.96, 95% CI: 1.34, 4.58 non-depressed), and conflict with the spouse was negatively associated with responsiveness (B=-1.02, 95% CI: -1.94, -0.09 depressed; B=-2.87, 95% CI: -4.36, -1.37 non-depressed). However, social support was related to responsiveness only in non-depressed women (B = 2.61, 95% CI: 1.14, 4.07). While spousal relationships and social support enhance maternal responsiveness, for depressed women, spousal relationships were particularly critical. In considering maternal-infant interventions to improve child development outcomes, our study indicates the importance of supportive relationships that foster effective responsiveness.

RESUMO

One factor potentially driving healthcare and hospital worker (HHW)'s declining mental health during the COVID-19 pandemic is feeling betrayed by institutional leaders, coworkers, and/or others' pandemic-related responses and behaviors. We investigated whether HHWs' betrayal-based moral injury was associated with greater mental distress and post-traumatic stress disorder (PTSD) symptoms related to COVID-19. We also examined if these associations varied between clinical and non-clinical staff. From July 2020 to January 2021, cross-sectional online survey data were collected from 1,066 HHWs serving COVID-19 patients in a large urban US healthcare system. We measured betrayal-based moral injury in three groups: institutional leaders, coworkers/colleagues, and people outside of healthcare. Multivariate logistic regression analyses were performed to investigate whether betrayal-based moral injury was associated with mental distress and PTSD symptoms. Approximately one-third of HHWs reported feeling betrayed by institutional leaders, and/or people outside healthcare. Clinical staff were more likely to report feelings of betrayal than non-clinical staff. For all respondents, 49.5% reported mental distress and 38.2% reported PTSD symptoms. Having any feelings of betrayal increased the odds of mental distress and PTSD symptoms by 2.9 and 3.3 times, respectively. These associations were not significantly different between clinical and non-clinical staff. As health systems seek to enhance support of HHWs, they need to carefully examine institutional structures, accountability, communication, and decision-making patterns that can result in staff feelings of betrayal. Building trust and repairing ruptures with HHWs could prevent potential mental health problems, increase retention, and reduce burnout, while likely improving patient care.

RESUMO

Food insecurity affects 14% of US homes with children and has been associated with increased mental health problems. Few studies have examined long-term consequences for mental health and the role of social policies. This study examined the association between childhood household food insecurity (HHFI) and young adult psychological distress, and the moderating role of caregiver psychological distress and the Supplemental Nutrition Assistance Program (SNAP) using data from the Panel Study of Income Dynamics (1995-2015). The sample comprised 2782 children ages 0-12 years in 1997. Past-year HHFI was measured using the USDA 18-item questionnaire in 1997, 1999, 2001 and 2003. Young adults' non-specific psychological distress was measured with the Kessler (K6) scale in 2005, 2007, 2009, 2011, 2013 and 2015. Three trajectories of food insecurity were identified: 1) Persistent food security (70.5%); 2) Intermediate/fluctuating food insecurity (24.6%), and; 3) Persistent food insecurity (4.9%). Compared to persistent food security, fluctuating and persistent food insecurity were associated with significantly higher levels of psychological distress. This association was robust to adjusting for socio-demographic factors, caregiver psychological distress, and family access to governmental supports: [Adj. ORs (95% CI's = 1.72 (1.59-1.85) and 2.06 (1.81-2.33)]. Having a caregiver who suffered from psychological distress (1997 and/or 2002) and growing up with persistent food insecurity placed children at greater risk for mental health problems. Access to SNAP attenuated this risk. Early HHFI is associated with psychological distress in young adulthood. Interventions to increase access to SNAP and address caregivers mental health may prevent mental health problems associated with childhood HHFI.

RESUMO

The psychological impact of indirect trauma is unknown among North Korean (NK) refugees. We aimed to investigate the effects of direct and indirect trauma on the mental health of NK refugees in South Korea and evaluate the potential moderating effect of acculturative stress in this association. Using respondent-driven sampling, we recruited 323 NK refugees for this retrospective study. We measured exposure to direct and indirect trauma as independent variables, and posttraumatic stress symptoms (PTSS) and symptoms of depression and anxiety as dependent variables. After implementing multivariate imputation using chained equations, the associations between trauma type and psychological outcomes were assessed using ordinary least squares regression analyses, controlling for demographic covariates; the potential effect modification of acculturative stress was studied by adding an interaction term to the analyses. PTSS and symptoms of depression and anxiety were significantly associated with exposure to both direct, Bs = 0.24, 0.16, 0.19, respectively, p < .001s, and indirect trauma, Bs = 0.13, 0.08, 0.07, respectively, ps < .001. Although we did not observe significant effect modification, the magnitude of association between indirect trauma and PTSS significantly differed between the high, B = 0.18, p < .001, and low acculturative stress groups, B = 0.08, p = .024. These findings suggest that indirect trauma is associated with a more severe mental health consequence among NK refugees who experience high acculturative stress. Efforts to mitigate acculturative stress may reduce the mental health consequences of indirect trauma exposure.

RESUMO

OBJECTIVES: Psychological distress in pregnancy is associated with adverse postnatal outcomes. We aimed to identify how social support and women's empowerment are associated with pregnancy-specific daily experiences among women suffering antenatal anxiety in Pakistan. METHODS: Data were collected as part of a randomized controlled trial of a psychosocial intervention for antenatal anxiety in a tertiary hospital in Pakistan. We included 594 women in early pregnancy (≤ 22 weeks) who endorsed mild to severe anxiety symptoms. Generalized linear regression models were used to analyze the associations of perceived social support and women's empowerment in relation to pregnancy-specific daily hassles and uplifts using a culturally adapted and psychometrically validated version of the Pregnancy Experience Scale-Brief. RESULTS: High social support was positively associated with frequency and intensity of positive pregnancy-specific experiences (B = 0.39, 95% CI 0.23-0.54 uplifts frequency; and B = 0.17, 95% CI 0.12-0.22 uplifts intensity), and was inversely associated with frequency of negative pregnancy-specific experiences (B = - 0.44, 95% CI - 0.66, - 0.22). Women's household empowerment was associated with greater uplifts frequency and intensity (B = 0.55, 95% CI 0.20-0.90 frequency; and B = 0.28, 95% CI 0.17-0.40 intensity). High social support and household empowerment were inversely related to PES hassle-to-uplift ratio scores. CONCLUSIONS FOR PRACTICE: Greater social support and household empowerment were associated with positive pregnancy-specific experiences in the context of antenatal anxiety in Pakistan.

RESUMO

This systematic review provides a comprehensive assessment of risk factors related to early sexual intercourse (ESI) among adolescents. We used PRISMA guidelines to identify eligible cohort studies published between January 1999 and December 2020. We searched on three databases: PubMed, Embase and LILACS. Studies were screened for quality and eligibility. Of 2787 identified studies, seven met our inclusion criteria. The studies examined a range of factors, which were organized into four dimensions - individual, family, social and environmental, and sociodemographic. Risk factors with strong associations for ESI were: adolescent and parental substance use, aggression and conduct disorders, family attachment, school achievement, family living situation, and maternal education. Three studies were birth cohorts. This review demonstrates the important roles of substance use, family attachment and academic factors in shaping adolescents' sexual behavior. A strength of this review is its focus on longitudinal studies, enabling exploration of exposures collected before initiation of sexual intercourse.

RESUMO

This study examined how different domains of social capital and of social support among caregivers are associated with social-emotional development in children ages 4-6 and how caregiver depressive symptoms modify these associations. Using a stratified random sample of preschools, data included a cross-sectional study of 1147 child-caregiver pairs (543 girls) in a low-income municipality in Brazil. Crude and adjusted linear regression models revealed that all domains of social support and two domains of social capital were associated with less social-emotional development delay in children. Given a significant proportion of children in low- and middle-income countries do not meet developmental milestones, strengthening caregiver social capital and support in these settings may have the potential to improve child social-emotional development.

RESUMO

Social influence can shape early childhood at different levels. We explored the association between social vulnerability and lifetime caregiver alcohol use with children's psychiatric symptoms. Multivariable logistic regression assessed the association between child psychiatric symptoms and social vulnerability among 1275 preschool child-caregiver pairs with lifetime caregiver alcohol used as a control variable. Of the children, 15.78% (95% CI 15.17-16.42) had internalizing symptoms, 2.49% (95% CI 2.19-2.83) had externalizing symptoms, and 9.36% (95% CI 8.88-9.86) had internalizing/externalizing symptoms. High social vulnerability was positively correlated with internalizing (aRRR 1.54; 95% CI 1.41-1.68) and internalizing/externalizing symptoms (aRRR 1.77; 95% CI 1.58-2.00). Low family support was strongly associated with internalizing/externalizing symptoms (aRRR 2.60; 95% CI 2.20-3.10). Lifetime caregiver alcohol use was positively correlated with all three psychiatric symptoms (aRRR 1.33; 95% CI 1.18-1.51; aRRR 1.13; 95% CI 1.06-1.59; and aRRR 1.26; 95% CI 1.12-1.42). Their association with children's mental health outcomes calls for social policy changes at the macrosystem level.

RESUMO

The goals of this study were to study relationships between maternal and children's dietary patterns (DPs) and to assess how children's DP was associated with child anthropometry. This cross-sectional study included 788 pairs of 6-year-old girls and mothers in health centers in Tehran, Iran. Information on dietary intake was collected with a 168-item food frequency questionnaire. Principal component factor analysis was performed to label different data-driven dietary patterns. Three different binary logistic regression models were used to evaluate the associations between child's DPs and child anthropometry. A positive correlation was found between all maternal patterns and child's Western DP (p < 0.001). Maternal prudent and Western DPs were correlated with child's high-protein DP (p < 0.001). Children's high-protein DP was negatively correlated with maternal high fat DP (p < 0.001). Maternal prudent and high fat DPs were correlated with prudent DP in children (p < 0.001). In adjusted models, a child being in the highest compared to the first quartile of the high-protein DP was associated with decreased odds of underweight and wasting (OR 0.43; 95% CI 0.23-0.80).Conclusion: The present study showed inverse associations between a high-protein DP in children and being underweight and wasted. Also, a positive correlation was found between all maternal DPs and children's Western DPs. This correlation should be taken into account while managing child nutrition by means of educating parents on the influence of their own dietary pattern on their children. Moreover, getting enough protein through a balanced diet should be considered in children. What is Known: • Some research exists on the intake of specific foods in relation to risk of abnormal growth in children. • Less is known about the relationship between mothers' and children's food intake. What is New: • Better adherence to a high-protein dietary pattern was significantly associated with lower risk of being both underweight and wasted. • This study suggests that correlation between mothers' and their children's dietary patterns exists, which should be taken into consideration when managing child nutrition.

RESUMO

OBJECTIVES: While increasing numbers of North Korean refugees (NKRs) are migrating to South Korea, different understandings of physical pain between NKR patients and the South Korean healthcare providers may create miscommunication and less satisfaction with their care management. To identify strategies to improve care, this study elicits and presents an ethnomedical model of chronic pain among NKR women. DESIGN: Twenty semi-structured individual interviews were conducted with NKR women with chronic pain living in South Korea. Inductive and deductive thematic analysis was performed on three types of data: interview transcripts, field notes created after each interview, and memos written during the analysis. RESULTS: Participants reported that pain started after a certain period of resettlement and expressed frustration when there was no definite diagnosis for pain. They identified physical factors (e.g. excessive labor, exposure to violence, and poor diet) as the primary causes, while psychological factors (e.g. loneliness, rumination, and financial burden of sending remittances to North Korea) were viewed as collateral or contributing causes. Several participants indicated emotional discomfort when they were referred to psychiatrists for unceasing pain. Physical treatment (injections, medications, or acupuncture) and providers' sincere attitudes were expectations of care considered capable of addressing both physical and emotional distress. CONCLUSIONS: Findings highlight the need to understand NKR women's ethnomedical model of chronic pain, which is distinct from illness model of healthcare providers. These preliminary findings could be used to improve care strategies based on NKRs' care needs.

RESUMO

OBJECTIVE: Breastmilk is considered an optimal food for infant development especially during the first 6 months of life. However, little evidence exists regarding maternal dietary intake and infant growth. We evaluated how adherence to the DASH diet in lactating women is associated with the infant weight, height and head circumference at birth, 2 and 4 months of age. STUDY DESIGN: A cross-sectional study. METHODS: The present study was conducted with 292 lactating mothers and their infants. A validated and reliable 168-item food frequency questionnaire (FFQ) was used to assess mothers' dietary intakes. To evaluate adherence to the DASH diet among lactating mothers, we scored food items based on the Fung method. RESULT: Lactating mothers in the highest tertile of adherence to the DASH diet consumed significantly lower amounts of fat, cholesterol, salt, red and process meats and higher amounts of vitamin C, B1, B9, whole grains, low-fat dairy, fruits, vegetables and dietary fiber compared to lactating mothers in the lowest tertile (P < 0.05). No significant association was found between mothers' adherence to the DASH dietary pattern and any of the infant growth indices (P > 0.05). CONCLUSION: Lactating mothers' adherence to the DASH diet was not associated with growth indices among exclusively breastfed infants.

RESUMO

How genes and parenting determine maternal social support availability, an important preventive factor of postpartum depression, has been little studied. Our study aimed to examine the interaction effects of maternal sociality-related gene and parenting on maternal social support. We analyzed data of 115 triads of Japanese grandmothers, mothers, and their infants. An interaction between parenting and cumulative genetic risk, calculated on the sociality-related genes (OXTR rs53576, rs2254298, rs1042778; COMT rs4680), was found. Mothers with high genetic risk received less social support if received poorer parenting (B = - 0.02, 95%CI = - 0.04 to - 0.01), while no association among low-risk mothers. Poorer social support was associated with severer depression in high-risk mothers (B = - 0.88, 95%CI = - 1.45 to -0.30). Our results suggest that mothers carrying risk alleles of sociality-related genes are particularly sensitive to childhood parenting, underscoring the importance of childhood parenting and genetic risk to understand maternal help-seeking behavior.

RESUMO

BACKGROUND: Maternal stress is potentially a modifiable risk factor for spontaneous preterm birth (sPTB). However, epidemiologic findings on the maternal stress-sPTB relationship have been inconsistent. METHODS: To investigate whether the maternal stress-sPTB associations may be modified by genetic susceptibility, we performed genome-wide gene × stress interaction analyses in 1490 African-American women from the Boston Birth cohort who delivered term (n = 1033) or preterm (n = 457) infants. Genotyping was performed using Illumina HumanOmni 2.5 array. Replication was performed using data from the NICHD genomic and Proteomic Network (GPN) for PTB research. RESULTS: rs35331017, a T-allele insertion/deletion polymorphism in the protein-tyrosine phosphatase receptor Type D (PTPRD) gene, was the top hit that interacted significantly with maternal lifetime stress on risk of sPTB (PG × E = 4.7 × 10-8). We revealed a dose-responsive association between degree of stress and risk of sPTB in mothers carrying the insertion/insertion genotype, but an inverse association was observed in mothers carrying the heterozygous or deletion/deletion genotypes. This interaction was replicated in African-American (PG × E = 0.088) and Caucasian mothers (PG × E = 0.023) from the GPN study. CONCLUSION: We demonstrated a significant maternal PTPRD × stress interaction on sPTB risk. This finding, if further confirmed, may provide new insight into individual susceptibility to stress-induced sPTB. IMPACT: This was the first preterm study to demonstrate a significant genome-wide gene-stress interaction in African Americans, specifically, PTPRD gene variants can interact with maternal perceived stress to affect risk of spontaneous preterm birth. The PTPRD × maternal stress interaction was demonstrated in African Americans and replicated in both African Americans and Caucasians from the GPN study. Our findings highlight the importance of considering genetic susceptibility in assessing the role of maternal stress on spontaneous preterm birth.

RESUMO

Sexual risk behaviors are closely related to the use of alcohol, tobacco, and other illicit drugs as well as teen dating violence. School-based drug prevention programs that teach social and personal skills could potentially also reduce sexual risk behaviors. We examined the effects of the #Tamojunto program on youth sexual risk behaviors. A randomized controlled trial was conducted with 6391 7th and 8th grade students in 72 public schools in six Brazilian cities. Baseline data were collected prior to program implementation. Two waves of follow-up assessments occurred after 9 and 21 months. Analyses were performed taking into account the multilevel structure of the data. We used intention-to-treat to evaluate changes in the prevalence of sexual risk behaviors over time and between groups. Adolescent age ranged from 11 to 15 years, with a mean of 12.6 ± 0.8 years, and 51.0% were female. Among all participants, receipt of #Tamojunto was associated with higher risk of lifetime sex at 21 months follow-up (OR 1.27, 95% CI [1.03, 1.56]). Among girls, at 9 months follow-up, the program was associated with higher likelihood of having engaged in sex in the last month (OR 1.76, 95% CI [1.13, 2.74]). At 21 months follow-up, girls receiving the program were more likely to report engaging in condomless sex in the last month (OR 1.64, 95% CI [1.07, 2.50]). #Tamojunto may be ineffective and possibly harmful for preventing sexual risk behaviors, especially among girls. We suggest further investigation of the possible mediating role of life skills intervention components on girl's sexual behaviors.

RESUMO

OBJECTIVE: B-vitamins affect brain function through multiple pathways. Given limited evidence on the relationship between dietary intake of these vitamins and psychological disorders, we examined dietary intake of vitamin B6-9-12 in relation to psychological disorders among Iranian women. DESIGN: Cross-sectional study. Dietary intake was assessed using a valid and reliable FFQ. To assess psychological disorders, we used a version of the Depression Anxiety Stress Scale-21 validated in Iran. SETTING: Ten public health centres in southern Tehran, Iran. PARTICIPANTS: A total of 447 female participants aged 20-50 years. RESULTS: The median values of vitamin B6 (pyridoxine), B9 (folate) and B12 (cobalamin) were 1·30 mg/d, 313·89 µg/d and 3·99 µg/d, respectively. After adjustment for potential confounders, dietary vitamin B6 intake was associated with lower odds of depression (OR: 0·54; 95 % CI: 0·31, 0·95; Ptrend: 0·03). However, there was a positive association between dietary vitamin B12 intake with the odds of depression (OR: 2·05; 95 % CI: 1·17, 3·60; Ptrend: 0·01) and psychological distress (OR: 2·00; 95 % CI: 1·17, 3·41; Ptrend: 0·01). No association was found between vitamin B9 with any psychological disorders. CONCLUSIONS: Women with higher dietary intakes of vitamin B6 had lower likelihood of depression. However, women with higher dietary intake of vitamin B12 had higher odds of depression and psychological distress. Future prospective studies in different populations are needed to clarify whether B-vitamin deficiency is a cause or consequence of psychological disorders.

RESUMO

PURPOSE: Racial/ethnic minorities experience disproportionate rates of depressive symptoms in the United States. The magnitude that underlying factors-such as social inequalities-contribute to these symptoms is unknown. We sought to identify exposures that explain racial/ethnic differences in clinically significant depressive symptomology among men who have sex with men (MSM). METHODS: Data from the Multicenter AIDS Cohort Study (MACS), a prospective cohort study, were used to examine clinically significant symptoms of depression (Center for Epidemiologic Studies Depression Scale score ≥ 20) among non-Latinx White, non-Latinx Black, and Latinx MSM. We included 44,823 person-visits by 1729 MSM seen in the study sites of Baltimore/Washington, DC; Chicago; Pittsburgh/Columbus; and Los Angeles from 2000 to 2017. Regression models estimated the percentage of depressive symptom risk explained by social, treatment, and health-related variables related to race/ethnicity. Machine-learning methods were used to predict the impact of mitigating differences in determinants of depressive symptoms by race/ethnicity. RESULTS: At the most recent non-missing MACS visit, 16% of non-Latinx White MSM reported clinically significant depressive symptoms, compared to 22% of non-Latinx Black and 25% of Latinx men. We found that income and social-environmental stress were the largest contributors to racial/ethnic disparities in risk for depressive symptoms. Similarly, setting the prevalence of these two exposures to be equal across racial/ethnic groups was estimated to be most effective at reducing levels of clinically significant depressive symptoms. CONCLUSION: Results suggested that reducing socioeconomic inequalities and stressful experiences may be effective public health targets to decrease racial/ethnic disparities in depressive symptoms among MSM.

RESUMO

In the US, the COVID-19 pandemic adds a new source of stress for women in the perinatal period, a time when stress and anxiety are already heightened. The closures of physical mental health care spaces and lack of support could have devastating impacts on the health of postpartum women and their newborns. Yet, the pandemic creates an opportunity to innovate in the ways mental health care is delivered to pregnant and postpartum women. With the expanded capacity for video and telephone visits, researchers should continue to explore solutions for providing support networks to this vulnerable population.
