Childhood parental bonding and depression in adulthood: A study of mothers in rural Pakistan

BACKGROUND

Parent-child relationship quality can have long-term impacts on child mental health into adulthood. The impact of parental behaviors on the future mental health of children has been understudied in South Asia, where parenting approaches differ from the dominant western approaches often represented in the literature.

METHODS

Mothers in rural Pakistan (N = 828) reported on their own mothers' parenting behaviors using the Parental Bonding Instrument (PBI) and were assessed for depression using the Structured Clinical Interview for DSM Disorders (SCID). The PBI includes scales for warmth (care scale) and over-control (protection scale), as well as subscales for behavioral control and psychological control. We used structural equation modeling to test the associations between depression and all PBI scales/subscales.

RESULTS

Increased parental care was associated with lower probability of depression (B = -0.19, SE = 0.09). Parental protection was associated with higher probability of depression (B = 0.25, SE = 0.11). Among the protection subscales, behavioral control was associated with increased risk of depression (B = 0.24, 95 % SE = 0.11) and psychological control was associated with decreased risk of depression (B = -0.28, SE = 0.12).

LIMITATIONS

This cross-sectional study used retrospective self-reports of parenting experiences. Participants only reported on their mothers, not fathers or other caregivers.

CONCLUSIONS

In a rural Pakistani sample, maternal warmth was protective against adulthood depression. The association between maternal control and depression varied based on the type of control (behavioral or psychological), emphasizing the importance of nuanced measures of parental control in this context.

Emotional and functional well-being in long-term breast cancer survivorship

PURPOSE

Emotional and functional well-being (EWB and FWB) are important components of mental health and quality of life. This study aims to evaluate long-term EWB and FWB in breast cancer (BC) survivors.

METHODS

The Carolina Breast Cancer Study Phase 3 oversampled Black and younger (< 50 years in age) women so that they each represent approximately 50% of the study population and assessed participants' EWB and FWB with the Functional Assessment of Cancer Therapy-Breast (FACT-B) at 5- (baseline), 25-, and 84-months post diagnosis. Multinomial logit models were used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for associations between demographic and clinical characteristics and well-being change relative to baseline.

RESULTS

Among 2,781 participants with BC, average EWB and FWB improved with time since diagnosis. Persistent FWB decrements were associated with Black race [OR 1.4 (95% CI 1.2-1.7) and 1.3 (95% CI 1.1-1.6), at 25-months and 84-months respectively], older age [OR 1.4 (95% CI 1.1-1.7) and 1.5 (95% CI 1.2-1.8), respectively], no chemotherapy, and recurrence [OR 2.9 (95% CI 1.8-4.8) and 3.1 (95% CI 2.1-4.6), respectively]. EWB decrements were associated with advanced stage and recurrence. Decrements in combined (FWB+EWB) well-being were associated with recurrence at both follow-up survey timepoints [ORs 4.7 (95% CI 2.7-8.0) and 4.3 (95% CI 2.8-6.6), respectively].

CONCLUSIONS

Long-term well-being varies by demographics and clinical features, with Black women and women with aggressive disease at greatest risk of long-term decrements.

Racial And Ethnic Inequities In Postpartum Depressive Symptoms, Diagnosis, And Care In 7 US Jurisdictions

Understanding whether racial and ethnic inequities exist along the postpartum mental health care continuum is vital because inequitable identification of depression can lead to inequitable referral to and receipt of care. We aimed to expand on existing cross-sectional and single-state data documenting potential racial and ethnic disparities in postpartum depression care. Using early (from two to six months) and late (from twelve to fourteen months) postpartum survey data from seven US jurisdictions, we documented patterns of early postpartum depressive symptoms, perinatal mood and anxiety disorder (PMAD) diagnosis, and receipt of postpartum mental health care overall and by racial and ethnic identity. Of 4,542 people who delivered live births in 2020, 11.8 percent reported early postpartum depressive symptoms. Among the sample with these symptoms, only 25.4 percent reported receiving a PMAD diagnosis, and 52.8 percent reported receiving some form of postpartum mental health care. There were no significant differences in diagnosis by race and ethnicity. Respondents identifying as Asian; Native Hawaiian or Pacific Islander; Southwest Asian, Middle Eastern, or North African; Hispanic; and non-Hispanic Black were significantly less likely than non-Hispanic White respondents to receive mental health care, demonstrating stark inequities in the management of postpartum depressive symptoms. Policies mandating and reimbursing universal postpartum depression screening, facilitating connection to care, reducing insurance coverage gaps, and enhancing clinician training in culturally responsive care may promote equitable postpartum mental health care.

Special Supplemental Nutrition Program for Women, Infants, and Children Participant Grocery Store Purchases during the COVID-19 Pandemic in North Carolina

Background

Families participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) experienced barriers to accessing healthy food during the COVID-19 pandemic, but we do not yet understand how WIC participant food purchases shifted during the pandemic.

Objectives

We aimed to describe the association between the initial shock of the pandemic in March 2020 and WIC shoppers' food purchases and changes in purchases before and during the pandemic at a top grocery chain and examine differences in these relationships by duration of WIC use.

Methods

We used longitudinal food transaction data from WIC shoppers (n = 2,989,116 shopper-month observations from 175,081 unique WIC shoppers) from 496 stores in a top grocery store chain in North Carolina between October 2019 and May 2021. We used an interrupted time series design to describe the following: 1) the relationship between the initial shock of the pandemic and WIC shopper food purchases and 2) differences in purchases before and during the pandemic. To assess differences in purchases between shoppers consistently using WIC electronic benefit transfer (EBT) cards and shoppers starting or stopping WIC EBT use during the pandemic, we used models stratified by WIC group. Primary outcomes were share (%) of total calories purchased from fruits, vegetables, nuts, and legumes (FV), processed foods, and sugar-sweetened beverages (SSBs).

Results

We observed small decreases in the share of total calories from FV (-0.4%) and small increases in the share of calories from processed food (1.1%) and SSBs (0.5%) purchased at this retailer when comparing the pre and post March 2020 periods. Compared with shoppers that started or stopped using WIC benefits during the pandemic, shoppers that used WIC benefits consistently had slightly higher FV and lower processed food and SSB purchases at this retailer.

Conclusions

Future studies should examine whether additional supports for nutrient-dense food choices may be needed for families with low incomes in public health emergencies.

Longitudinal pathways between maternal depression, parenting behaviors, and early childhood development: a mediation analysis

Maternal depression is a global public health concern with far-reaching impacts on child development, yet our understanding of mechanisms remains incomplete. This study examined whether parenting mediates the association between maternal depression and child outcomes. Participants included 841 rural Pakistani mother-child dyads (50% female). Maternal depression was measured at 12 months postpartum, parenting behaviors (warmth, stimulation, and harsh parenting) were measured at 24 months, and child outcomes (mental health, socioemotional development, and cognitive skills) were measured at 36 months. Maternal depression predicted increased harsh parenting, child mental health difficulties, and child socioemotional concerns; however, there was little evidence for parenting as a mediator between maternal depression and child outcomes. Sex-stratified results are discussed, and findings are situated in context.

Suicide Ideation within and outside the Perinatal Period: An Exploration of Interpersonal Factors from a Maternal Cohort in Rural Pakistan to Improve Intervention Targeting

OBJECTIVE

Suicide accounts for substantial mortality in low-resourced settings and contributes to nearly 20% of maternal deaths. In Asia, interpersonal conflict is a salient factor that contributes to suicidal thoughts and actions, yet limited research has been done to explore the type and timing of such conflicts and a woman's accompanying social support. Identifying such risk factors can inform improved efforts to identify who to target for psychosocial interventions.

METHODS

Using the Bachpan Cohort study of mothers in Pakistan (n = 1154), we examined the prevalence and interpersonal influences on SI within the past two weeks of pregnancy and then at 3, 6, and 24 months after birth. Using hierarchical mixed effects models, we explored the separate and combined associations of interpersonal factors [e.g., social support, interpersonal conflict, isolation, and past year intimate partner violence (IPV)] on SI at each timepoint.

RESULTS

SI prevalence was highest in pregnancy (12.2%) and dropped to 5% throughout two years postpartum. The interpersonal conflict was independently associated with increased odds of SI in pregnancy and 24 months postpartum. IPV was associated with increased SI in pregnancy and 24 months postpartum. Isolation was not associated with SI at any timepoint. Perceived social support remained a robust independent factor associated with reduced SI at all timepoints.

CONCLUSION

In addition to screening and deploying interventions for perinatal women with depression, targeting interventions for those who also experience interpersonal conflict, including intimate partner violence, may significantly reduce suicidal thoughts and related sequelae. Social support is a viable and potentially powerful target to reduce the burden of suicide among women.HIGHLIGHTSSuicidal ideation prevalence was higher in pregnancy compared to postpartum.Perceived social support was independently associated with reduced suicidal ideation.Interventions addressing suicide must attend to women's family and social context.

Does biological age mediate the relationship between childhood adversity and depression? Insights from the Detroit Neighborhood Health Study

The link between childhood adversity and adulthood depression is well-established; however, the underlying mechanisms are still being explored. Recent research suggests biological age may mediate the relationship between childhood adversity and depression in later life. This study examines if biological age mediates the relationship between childhood adversity and depression symptoms using an expanded set of biological age measures in an urban population-based cohort. Data from waves 1-3 of the Detroit Neighborhood Health Study (DNHS) were used in this analysis. Questions about abuse during childhood were coded to form a childhood adversity score similar to the Adverse Childhood Experience measure. Multiple dimensions of biological age, defined as latent variables, were considered, including systemic biological age (GrimAge, PhenoAge), epigenetic age (Horvath, SkinBlood), and immune age (cytomegalovirus, herpes simplex virus type 1, C-reactive protein, interleukin-6). Depression symptoms, modeled as a latent variable, were captured through the Patient Health Questionnaire-9 (PHQ-9). Models were adjusted for age, gender, race, parent education, and past depressive symptoms. Total and direct effects of childhood adversity on depression symptoms and indirect effects mediated by biological age were estimated. For total and direct effects, we observed a dose-dependent relationship between cumulative childhood adversity and depression symptoms, with emotional abuse being particularly influential. However, contrary to prior studies, in this sample, we found few direct effects of childhood adversity on biological age or biological age on depression symptoms and no evidence of mediation through the measures of biological age considered in this study. Further research is needed to understand how childhood maltreatment experiences are embodied to influence health and wellness.

Gender differences in the surgical management of trachomatous trichiasis: an exploratory analysis of global trachoma survey data, 2015-2019

BACKGROUND

Trachomatous trichiasis (TT) is a painful, potentially blinding eye condition that can be managed through epilation or surgery. Women are affected by TT approximately twice as often as men and are believed to face gendered barriers to receiving surgical care to prevent vision loss.

METHODS

We used data from 817 cross-sectional surveys conducted during 2015-2019 in 20 African countries to estimate the prevalence difference (PD) between female and male eyes for four outcomes potentially indicating gender-related differences in TT management: (1) received surgery and developed postoperative TT (PTT), (2) never offered surgery, (3) offered surgery but declined it, and (4) offered epilation but never offered surgery.

RESULTS

The prevalence was modestly elevated among female eyes compared with male eyes for having PTT (PD:1.8 [95% confidence limits (CL): 0.6, 3.0]) and having declined surgery for the eye (PD: 6.2 [95% CL: 1.8, 10.7]). The proportion offered epilation was similar by gender (PD:0.5 [95% CL: -0.4, 1.3]), while never having been offered surgery was somewhat more prevalent among male eyes (PD: -2.1 [95% CL: -3.5, -0.7]).

CONCLUSIONS

Our results suggest potential gender differences in TT management. More research is needed to determine the causes and implications of the observed differences.

Maternal adverse childhood experiences on child growth and development in rural Pakistan: An observational cohort study

Maternal adverse childhood experiences (ACEs) have significant impacts on the next generation with links to negative birth outcomes, impaired cognitive development, and increased socioemotional problems in children. However, not all types or levels of adversity are similarly deleterious and research from diverse contexts is needed to better understand why and how intergenerational transmission of adversity occurs. We examined the role of maternal ACEs on children's growth, cognitive, and socioemotional development at 36 months postpartum in rural Pakistan. We used data from 877 mother-child dyads in the Bachpan Cohort, a birth cohort study. Maternal ACEs were captured using an adapted version of the ACE-International Questionnaire. Outcomes at 36 months of age included child growth using the WHO growth z-scores, fine motor and receptive language development assessed with the Bayley Scales of Infant and Toddler Development, and socioemotional and behavioral development measured with the Ages and Stages Questionnaire: Socioemotional and Strengths and Difficulties Questionnaire. To estimate the associations between maternal ACEs and child outcomes, we used multivariable generalized linear models with inverse probability weights to account for sampling and loss to follow-up. Over half of mothers in our sample (58%) experienced at least one ACE. Emotional abuse, physical abuse, and emotional neglect were the most commonly reported ACEs. We found null relationships between the number of maternal ACEs and child growth. Maternal ACEs were associated with higher fine motor and receptive language development and worse socioemotional and behavioral outcomes. Maternal ACE domains had similarly varying relationships with child outcomes. Our findings highlight the complexity of intergenerational associations between maternal ACEs and children's growth and development. Further work is necessary to examine these relationships across cultural contexts and identify moderating factors to mitigate potential negative intergenerational effects.

Non-linear associations between HPA axis activity during infancy and mental health difficulties during early childhood among children in rural Pakistan

Hypothalamic pituitary adrenal (HPA) axis activity may be a mechanism linking early adversity to child mental health difficulties. However, there is a dearth of longitudinal evidence for the association between HPA axis activity and mental health among children in low-resource contexts. The goal of this study is to examine linear and curvilinear associations between HPA axis activity during infancy and mental health difficulties in early childhood among children in rural Pakistan. Participants included 104 children (46% male) from the Bachpan study, a longitudinal cohort embedded within a maternal depression trial in Pakistan. We examined the associations between hair-derived cortisol and dehydroepiandosterone (DHEA) at 12 months old and mental health difficulties, measured with the Strengths and Difficulties Questionnaire (SDQ), at 36 months old. There was a significant quadratic association between hair cortisol and SDQ scores, with results showing a U-shaped relationship (i.e., having relatively high or low cortisol predicted increased mental health difficulties). DHEA showed a quadratic association with SDQ scores with an inverted U-shaped relationship (i.e., high and low DHEA was associated with decreased mental health difficulties). Results provide evidence of longitudinal and curvilinear effects of cortisol and DHEA during infancy on mental health difficulties in early childhood.

Understanding the effects of universal test and treat on longitudinal HIV care outcomes among South African youth: a retrospective cohort study

INTRODUCTION

Little is known about the effects of universal test and treat (UTT) policies on HIV care outcomes among youth living with HIV (YLHIV). Moreover, there is a paucity of information regarding when YLHIV are most susceptible to disengagement from care under the newest treatment guidelines. The longitudinal HIV care continuum is an underutilized tool that can provide a holistic understanding of population-level HIV care trajectories and be used to compare treatment outcomes across groups. We aimed to explore effects of the UTT policy on longitudinal outcomes among South African YLHIV and identify temporally precise opportunities for re-engaging this priority population in the UTT era.

METHODS

Using medical record data, we conducted a retrospective cohort study among youth aged 18-24 diagnosed with HIV from August 2015-December 2018 in nine health care facilities in South Africa. We used Fine and Gray sub-distribution proportional hazards models to characterize longitudinal care continuum outcomes in the population overall and stratified by treatment era of diagnosis. We estimated the proportion of individuals in each stage of the continuum over time and the restricted mean time spent in each stage in the first year following diagnosis. Sub-group estimates were compared using differences.

RESULTS

A total of 420 YLHIV were included. By day 365 following diagnosis, just 23% of individuals had no 90-or-more-day lapse in care and were virally suppressed. Those diagnosed in the UTT era spent less time as ART-naïve (mean difference=-19.3 days; 95% CI: -27.7, -10.9) and more time virally suppressed (mean difference = 17.7; 95% CI: 1.0, 34.4) compared to those diagnosed pre-UTT. Most individuals who were diagnosed in the UTT era and experienced a 90-or-more-day lapse in care disengaged between diagnosis and linkage to care or ART initiation and viral suppression.

CONCLUSIONS

Implementation of UTT yielded modest improvements in time spent on ART and virally suppressed among South African YLHIV- however, meeting UNAIDS' 95-95-95 targets remains a challenge. Retention in care and re-engagement interventions that can be implemented between diagnosis and linkage to care and between ART initiation and viral suppression (e.g., longitudinal counseling) may be particularly important to improving care outcomes among South African YLHIV in the UTT era.

The Day-in-the-Life method for assessing infant caregiving in rural Pakistan

Objective

This manuscript describes the Day-in-the-Life (DIL) method for assessing child caregiving activities, its implementation, and findings regarding family members' roles and associations with maternal depression symptoms.

Background

Infant caregiving activities are most commonly performed by the mother, although there is increasing acknowledgement of others' contribution. Few methods exist to measure the diverse caregiving activities that mothers and others perform.

Method

Method development occurred within the Bachpan Cohort Study in rural Pakistan (N = 1,154 maternal-child dyads) when the child was 3 months old. The DIL was designed as a semi-structured interview in which the mother describes her child's day from their perspective. Regression analyses were then used to explore the correlation between the DIL and depression symptoms, using the Patient Health Questionnaire-9 (PHQ-9) measure.

Results

The DIL method was easy to administer and displayed excellent interrater agreement. The findings indicated that instrumental caregiving was mostly provided by the mother alone, others in the household tended to contribute more to infant social interactions, and there was more support from others when the mother was less able to provide care (e.g., when ill). Depression symptoms were higher among women who experienced less contribution from family members when the mother was less able to provide care.

Conclusions

The DIL can be deployed to measure infant caregiving activities and associations with maternal mental health.

Implications

This method is promising for researchers interested in disentangling the contribution of multiple family members toward child caregiving and its impacts on maternal and child health.

Residential segregation and prenatal depression in a non-Hispanic Black and Hispanic cohort in North Carolina

PURPOSE

Investigate residential segregation and prenatal depression in a non-Hispanic (NH) Black and Hispanic North Carolina pregnancy cohort.

METHODS

Demographics, prenatal depression (Center for Epidemiological Studies Depression scale ≥16), and residence from the 2006-2009 Newborn Epigenetic Survey were linked to Census-tract levels of racial and economic segregation (Index of Concentration at the Extremes) from the American Community Survey 2005-2009 5-year estimates. Adjusted prevalence ratios (aPR) for prenatal depression compared living in Index of Concentration at the Extremes tertiles 1 and 2 (higher proportion NH Black or Hispanic and/or low income) to 3 (higher proportion NH white and/or high-income), accounting for neighborhood clustering, age, education, employment, parity, and marital status.

RESULTS

Among the 773 survey participants (482 NH Black and 291 Hispanic), 35.7% and 27.2% of NH Black and Hispanic participants had prenatal depression, respectively. For NH Black participants, depression prevalence was 17% lower for tertile 1 versus 3 for the NH Black/white (aPR=0.83; 95% CI=0.62-1.10), low/high income (aPR=0.83; 95% CI=0.62-1.11), and low-income NH Black/high-income NH white (aPR=0.82; 95% CI=0.61-1.09) measures. For Hispanic participants, estimates were weaker in the opposite direction for the Hispanic/NH white (aPR=1.02; 95% CI=0.71-1.47), low/high income (aPr=1.14; (95% CI=0.76-1.69), and low-income Hispanic/high-income NH white (aPR=1.12; 95% CI=0.78-1.60) measures.

CONCLUSIONS

Residential segregation's impact on prenatal depression may differ by race/ethnicity and level of segregation, but findings are imprecise due to small sample sizes. Longitudinal research spanning greater geographic areas is needed.

Generativity and Engagement in Grandparenting Activities Among Older Adults in Northern Sri Lanka

Generativity refers to the desire to pass on one's skills, knowledge, and wisdom to future generations; this may be a clear indicator of the likelihood of older adults investing time and effort in engagement with their grandchildren. This cross-sectional study examines the relationship between generative beliefs and an index of multiple potential grandparenting activities. The data come from a convenience sample of 79 grandparents (aged 55+) living in Sri Lanka, a society experiencing rapid growth in its population of older adults. Regression analyses demonstrate that more endorsement of generative beliefs among older adults is associated with increased engagement in various grandparenting activities, with the strongest associations with reading, singing songs, and helping grandchildren with schoolwork or teaching them. Our findings suggest that generativity may be important for understanding the relationship between grandparenting and improved well-being for older adults.

Mother-in-law childcare and perinatal depression in rural Pakistan

BACKGROUND

Mothers-in-law often provide key childcare support to daughters-in-law during the perinatal period that may enhance maternal mental health. Yet, poor mother-in-law/daughter-in-law relationships may be associated with maternal depression. The extent to which mother-in-law childcare involvement affects perinatal depression may differ across contexts of family conflict.

OBJECTIVE

We explored the relationship between mother-in-law childcare and daughter-in-law perinatal depression in rural Pakistan across contexts of family conflict.

METHODS

Data on 783 women came from the Bachpan Cohort, a birth cohort in Pakistan. Maternally-reported mother-in-law childcare was assessed at 3 and 12 months postpartum using a 24-h recall and categorized into no, low, and high involvement. Major depression was captured at 3 and 12 months using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders IV. Family conflict was captured using three items from the Life Events Checklist. Log-Poisson models were used to estimate cross-sectional associations between mother-in-law childcare and perinatal depression, stratified by family conflict.

RESULTS

Mother-in-law childcare was common in the first year postpartum. The association between mother-in-law childcare and perinatal depression differed by the presence of family conflict and postpartum timing. At 3 months postpartum, low and high mother-in-law childcare (vs no involvement) were associated with a lower prevalence of depression regardless of family conflict. At 12 months postpartum, among families with no conflict, low mother-in-law childcare (vs no involvement) was associated with lower perinatal depression; however, among families with conflict, high mother-in-law childcare was associated with increased perinatal depression.

CONCLUSION

Our findings highlight the complexities of associations between mother-in-law childcare support and perinatal depression in the first year after birth. Mother-in-law childcare in the immediate postpartum period was beneficial for mothers. Understanding the source, amount, timing, and context of social support is necessary to inform research and interventions that aim to improve maternal mental health.

Stressful life events, intimate partner violence, and perceived stress in the postpartum period: longitudinal findings in rural Pakistan

PURPOSE

While the association between intimate partner violence (IPV) and stress is well documented, the directionality of this relationship is unclear. We use an adjusted longitudinal study design to better understand if stressful life events in the home precipitate or exacerbate intimate partner violence (IPV) and if experiences of IPV, in turn, increase levels of perceived stress.

METHODS

Longitudinal data were collected among married women in rural Pakistan at 12 and 24 months postpartum (N = 815). Adjusted Poisson and linear regression models were used to examine stressful life events, past year IPV and severity (number and frequency of violent acts), and perceived stress (Cohen Perceived Stress Scale).

RESULTS

At 12 months postpartum, the prevalence of past year physical, psychological, and sexual IPV was 8.5%, 25.7%, and 25.1%, respectively, with 42.6% experiencing any IPV. After adjustment, stressful life events were associated with a subsequent increased likelihood of all IPV types and increased severity of all but physical IPV. Any past year IPV (versus none) and greater IPV severity were associated with 3.43 (95% CI 2.33-4.52) and 2.57 (95% CI 1.87-3.27) point subsequent increases in perceived stress. Physical, psychological, and sexual IPV and their respective severities were all independently associated with increased perceived stress.

CONCLUSIONS

Among postpartum women in Pakistan, stressful life events increase the likelihood of IPV and, in turn, experiences of IPV increase stress levels. Support to families undergoing stressful circumstances may be critical to reducing women's IPV exposure and resulting elevated stress.

Lifecourse Traumatic Events and Cognitive Aging in the Health and Retirement Study

INTRODUCTION

Much of the heterogeneity in the rate of cognitive decline and the age of dementia onset remains unexplained, and there is compelling data supporting psychosocial stressors as important risk factors. However, the literature has yet to come to a consensus on whether there is a causal relationship and, if there is, its direction and strength. This study estimates the relationship between lifecourse traumatic events and cognitive trajectories and predicted dementia incidence.

METHODS

Using data on 7,785 participants aged ≥65 years from the Health and Retirement Study, this study estimated the association between lifecourse experience of 10 traumatic events (e.g., losing a child) and trajectories of Telephone Interview for Cognitive Status from 2006 to 2016 using linear mixed-effects models and predicted incident dementia from 2006 to 2014 using cumulative incidence functions (data analysis was in 2020-2022). Inverse probability weights accounted for loss to follow-up and confounding by sex, education, race/ethnicity, and age.

RESULTS

Experiencing 1 or more traumatic events over the lifecourse was associated with accelerated decline compared with experiencing no events (e.g., β= -0.05 [95% CI= -0.07, -0.02] Health and Retirement Study-Telephone Interview for Cognitive Status units/year; 1 vs 0 events). In contrast, experiencing traumatic events was associated with better cognitive function cross-sectionally. Furthermore, the impact of trauma on cognitive decline was of greater magnitude when it occurred after the age of 64 years. However, the magnitude and direction of association varied by the specific traumatic event. There were no associations with predicted incident dementia.

CONCLUSIONS

These results suggest that researchers and clinicians should not aggregate traumatic events for understanding the risk of accelerated cognitive decline.

Adverse childhood experiences and implications of perceived stress, anxiety and cortisol among women in Pakistan: a cross-sectional study

OBJECTIVES

Adverse childhood experiences (ACEs) are linked to poor maternal mental health. The goal of this study is to examine the associations between ACEs and multiple manifestations of stress (including perceived stress, anxiety and cortisol) among mothers in rural Pakistan.

DESIGN

This study used a cross-sectional design. Mothers were originally recruited during their third trimester of pregnancy and followed until 36 months post partum. Cortisol was collected at 12 months post partum, and self-report data were collected at 36 months post partum.

SETTING

All participants reside in rural villages in Rawalpindi, Pakistan. The measures were administered at home visits by field interviewers.

PARTICIPANTS

Data were collected from 889 mothers. All mothers in the sample provided data on ACEs and perceived stress, 623 provided data on anxiety and 90 provided hair cortisol.

PRIMARY AND SECONDARY OUTCOMES MEASURES

ACEs were captured retrospectively using an adapted version of the ACE International Questionnaire, and represented as a continuous variable and subdomains (neglect, home violence, family psychological distress, community violence). Primary outcomes included perceived stress measured with the Cohen Perceived Stress Scale (PSS) and anxiety measured with the Generalised Anxiety Disorder-7 scale (GAD-7). Hair-derived cortisol was included as a secondary outcome. Generalised linear models with cluster-robust SEs were used to estimate associations between ACEs and the outcome variables.

RESULTS

All models featured positive associations between ACE items and PSS. The continuous total ACE score (B=0.4; 95% CI 0.0 to 0.8) was associated with higher anxiety symptoms on the GAD-7. Home violence (B=6.7; 95% CI 2.7 to 10.8) and community violence (B=7.5; 95% CI 1.4 to 13.6) were associated with increased hair cortisol production.

CONCLUSIONS

All four ACE domains were associated with elevated levels of perceived stress, anxiety and cortisol, with varying precision and strength of estimates, indicating that the type of ACE has a differential impact. This study informed our understanding of the differential impact of specific ACEs on perceived stress, anxiety and hypothalamic pituitary adrenal-axis functioning, providing implications for future clinical intervention and research development.

Grandparenting activities and mental health in Northern Sri Lanka

Grandparenting activities are of increasing interest to researchers seeking to understand reduced social engagement and depression among aging adults. Heterogeneity in the population and caretaking roles complicate its measurement. We piloted a measure of grandparenting activities among 79 grandparents (aged 55+) in Sri Lanka and correlated those activity levels with psychological distress. Second, we explored whether the aforementioned correlation varied by grandparent functional limitations. We found that greater engagement in generative grandparenting activities was correlated with lower distress, and that association was stronger among grandparents with more functional limitations. We discuss possible explanations and implications of these findings.

The relationship of cumulative psychosocial adversity with antepartum depression and anxiety

BACKGROUND

Exposure to multiple psychosocial risk factors may increase vulnerability for mental health conditions during pregnancy. This analysis examined the relationship of a novel psychosocial adversity index with the co-occurrence and persistence of depression and anxiety throughout pregnancy.

METHODS

This cross-sectional analysis included 1797 pregnant women screened in the second/third trimesters for depression and anxiety symptoms and for eight contextual and individual psychosocial factors. The factors were summed to create a psychosocial adversity index; reporting four or more factors indicated high adversity. Elevated symptoms in both trimesters indicated persistent depression/anxiety and elevated symptoms at the same trimester indicated comorbid symptoms. The associations between the psychosocial adversity index and mental health were estimated.

RESULTS

Compared with a low psychosocial adversity index, women reporting a high level of psychosocial adversities had 2.06 (95% confidence interval [CI]: 1.51-2.82) times higher adjusted odds of only depressive or anxiety symptoms, and 5.57 (95% CI: 3.95-7.85) times higher adjusted odds of comorbid symptoms. The associations for persistent symptoms were of similar direction and magnitude.

CONCLUSION

High psychosocial adversity was associated with persistent and comorbid depressive symptoms and anxiety during pregnancy. Assessing psychosocial adversity can help identify women at increased risk who would benefit from tailored mental health interventions.

Longitudinal effects of perinatal social support on maternal depression: a marginal structural modelling approach

BACKGROUND

Depression in the perinatal period, during pregnancy or within 1 year of childbirth, imposes a high burden on women with rippling effects through her and her child's life course. Social support may be an important protective factor, but the complex bidirectional relationship with depression, alongside a paucity of longitudinal explorations, leaves much unknown about critical windows of social support exposure across the perinatal period and causal impacts on future depressive episodes.

METHODS

This study leverages marginal structural models to evaluate associations between longitudinal patterns of perinatal social support and subsequent maternal depression at 6 and 12 months postpartum. In a cohort of women in rural Pakistan (n=780), recruited in the third trimester of pregnancy and followed up at 3, 6 and 12 months postpartum, we assessed social support using two well-validated measures: the Multidimensional Scale of Perceived Social Support (MSPSS) and the Maternal Social Support Index (MSSI). Major depressive disorder was assessed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM IV).

RESULTS

High and sustained scores on the MSPSS through the perinatal period were associated with a decreased risk of depression at 12 months postpartum (0.35, 95% CI: 0.19 to 0.63). Evidence suggests the recency of support also matters, but estimates are imprecise. We did not find evidence of a protective effect for support based on the MSSI.

CONCLUSIONS

This study highlights the protective effect of sustained social support, particularly emotional support, on perinatal depression. Interventions targeting, leveraging and maintaining this type of support may be particularly important for reducing postpartum depression.

A Mixed-Methods Process Evaluation: Integrating Depression Treatment Into HIV Care in Malawi

BACKGROUND

Depression is highly prevalent among people living with HIV in Malawi. Depression can undermine engagement in HIV care and worsen HIV morbidity and mortality. The Ministry of Health integrated a pilot depression management program into HIV care at 2 clinics. This program included a measurement-based care protocol for prescribing antidepressants and an adapted Friendship Bench psychotherapy protocol for providing problem solving. Early evaluations indicated successful integration of the initial stages of training and depression screening, diagnosis, and treatment initiation. This follow-up mixed-method investigation contextualizes our previous findings and shares insights from the implementation experience.

METHODS

We conducted a mixed-methods process evaluation drawing on both patient clinical data and qualitative interviews with patients and clinic staff. We focus on the following implementation outcomes: fidelity, acceptability, and sustainability.

RESULTS

Although fidelity to depression screening and treatment initiation was high, fidelity to the follow-up treatment protocol was poor. Antidepressants and problem-solving therapy were acceptable to patients, but clinic staff found delivering treatment challenging given constrained human resources and infrastructure. The program was not sustained after the project. Key identified needs included substantial support to supervise the implementation of the program, continue to build and maintain the capacity of providers, integrate the program into the electronic medical records system, and ensure the availability of Friendship Bench counselors.

CONCLUSIONS

Although initial steps were successful, sustained integration of this depression treatment program into HIV care in this setting met greater challenges. Implementation science studies that support both implementation and evaluation should recognize the potential for clinical implementers to rely on evaluation staff for clinical support and consider distancing evaluation staff from the actual program implementation. Further research is needed to test enhanced implementation strategies for integrating evidence-based mental health interventions into existing health care systems in a sustainable fashion, particularly in low-resource settings.

Psychometric Validation of the Multidimensional Scale of Perceived Social Support During Pregnancy in Rural Pakistan

Background: The Multidimensional Scale of Perceived Social Support (MSPSS) is a short and reliable instrument that assesses perceived social support from the social network of an individual. A previous study in Pakistan among postpartum women has demonstrated a unidimensional factor structure in contrast to the original three-factor structure. The emergence of a one-factor structure for postpartum women in Pakistan may be due to traditional postpartum practices unique to the women of the subcontinent. Building upon the previous evidence, this study aims to explore the psychometric properties of MSPSS among pregnant women in their third trimester in rural Pakistan.

Methods: A cross-sectional survey was conducted from October 2014 to February 2016, in rural Pakistan. A sample of 1,154 pregnant women (aged ≥ 18 years) in their third trimester who were registered with the local Lady Health Worker Program and were living in the north of the Punjab Province was included in this study. They were assessed using Urdu translated scales of Patient Health Questionnaire, MSPSS, Maternal Social Support Index, and Perceived Stress Scale. Principal Axis Factoring was used to assess the construct validity of the MSPSS.

Results: The MSPSS scale showed an excellent internal consistency, yielding a Cronbach's α-value of 0.933. The MSPSS scale exhibited an excellent construct validity, and confirmatory factor analysis retained three factors (family, friends, and significant others) for both the depressed and non-depressed samples. Internal reliability and construct validity were also established.

Conclusion: The psychometric findings suggest that the tridimensional structure of MSPSS is a valid and reliable measure of perceived social support among the Pakistani population with and without perinatal depression. The perceived social support is an important predictor of maternal mental well-being and psychopathologies, and the MSPSS can serve as a useful tool in mental health research in Pakistan.

Association Between Depression and HIV Care Engagement Outcomes Among Patients Newly Initiating ART in Lilongwe, Malawi

As in other sub-Saharan countries, the burden of depression is high among people living with HIV in Malawi. However, the association between depression at ART initiation and two critical outcomes-retention in HIV care and viral suppression-is not well understood. Prior to the launch of an integrated depression treatment program, adult patients were screened for depression at ART initiation at two clinics in Lilongwe, Malawi. We compared retention in HIV care and viral suppression at 6 months between patients with and without depression at ART initiation using tabular comparison and regression models. The prevalence of depression among this population of adults newly initiating ART was 27%. Those with depression had similar HIV care outcomes at 6 months to those without depression. Retention metrics were generally poor for those with and without depression. However, among those completing viral load testing, nearly all achieved viral suppression. Depression at ART initiation was not associated with either retention or viral suppression. Further investigation of the relationship between depression and HIV is needed to understand the ways depression impacts the different aspects of HIV care engagement.

Adverse childhood experiences and depression among women in rural Pakistan

BACKGROUND

Adverse Childhood Experiences (ACEs) are a common pathway to adult depression. This pathway is particularly important during the perinatal period when women are at an elevated risk for depression. However, this relationship has not been explored in South Asia. This study estimates the association between ACEs and women's (N = 889) depression at 36 months postpartum in rural Pakistan.

METHOD

Data come from the Bachpan Cohort study. To capture ACEs, an adapted version of the ACE-International Questionnaire was used. Women's depression was measured using both major depressive episodes (MDE) and depressive symptom severity. To assess the relationship between ACEs and depression, log-Poisson models were used for MDE and linear regression models for symptom severity.

RESULTS

The majority (58%) of women experienced at least one ACE domain, most commonly home violence (38.3%), followed by neglect (20.1%). Women experiencing four or more ACEs had the most pronounced elevation of symptom severity (β = 3.90; 95% CL = 2.13, 5.67) and MDE (PR = 2.43; 95% CL = 1.37, 4.32). Symptom severity (β = 2.88; 95% CL = 1.46, 4.31), and MDE (PR = 2.01; 95% CL = 1.27, 3.18) were greater for those experiencing community violence or family distress (β = 2.04; 95%; CL = 0.83, 3.25) (PR = 1.77; 95% CL = 1.12, 2.79).

CONCLUSIONS

Findings suggest that ACEs are substantively distinct and have unique relationships to depression. They signal a need to address women's ACEs as part of perinatal mental health interventions and highlight women's lifelong experiences as important factors to understanding current mental health.

Locally contextualizing understandings of depression, the EPDS, and PHQ-9 among a sample of postpartum women living with HIV in Malawi

BACKGROUND

The Edinburgh Postnatal Depression Scale (EPDS) and Patient Health Questionnaire-9 (PHQ-9) are widely used depression screening tools, yet perceptions and understandings of their questions and of depression are not well defined in cross-cultural research.

METHODS

30 postpartum women living with HIV in Malawi were recruited from a cohort study and participated in in-depth cognitive interviews. Transcripts were evaluated following an inductive approach to identify common themes.

RESULTS

Participants most frequently described looking sad or different than usual, self-isolation, 'thinking too much,' and anger as key symptoms of being depressed. HIV-associated stigma was commonly identified as a cause of depression. The EPDS and PHQ-9 were generally well understood but did not capture all the important symptoms of depression that women described. Participants sometimes requested clarification or rephrasing of certain EPDS and PHQ-9 questions when asked to explain the questions' meanings in their own words, and requested rephrasing more often for EPDS questions than PHQ-9 questions. Few women believed either tool was sufficient to detect depression.

LIMITATIONS

Our results may not be generalizable, but are locally contextualized. Women suffering with depression may have been more or less likely to agree to the qualitative interview depending on their comfort level discussing any current depressive symptoms.

CONCLUSIONS

Researchers and practitioners who use the EPDS and PHQ-9 should be aware of the tools' limitations in their context and population. New instruments may need to be developed or adaptations to existing tools made to improve accuracy of depression screening and diagnosis in different cultural contexts.

Association of maternal depression and home adversities with infant hypothalamic-pituitary-adrenal (HPA) axis biomarkers in rural Pakistan

BACKGROUND

Each year, almost 35% of children are exposed to maternal depression and more grow up in persistent poverty, increasing the risk for stress-related disease and other socio-developmental deficits later in life. These impacts are likely related to chronic stress via the hypothalamic-pituitary-adrenal (HPA) axis. However, there is little evidence relating early windows of child HPA axis activity to multiple exposures.

METHODS

We investigated chronic measures of hair-derived HPA axis hormones (cortisol and dehydroepiandrosterone (DHEA)) in 104 one-year old infants from rural Pakistan and longitudinal measures of maternal depression, intimate partner violence (IPV), socio-economic status (SES), and the home environment.

RESULTS

Estimates from adjusted linear mixed effects models did not reveal consistent significant associations between infant cortisol and maternal depression or home adversities. By contrast, infants exposed to maternal depression during pregnancy had lower DHEA levels (ß= -0.18 95% confidence interval [CI]: -0.34, -0.02) as did those whose mothers experienced multiple types of IPV (ß=-4.14 95% CI: -7.42, -0.79) within one year postpartum. Higher SES had a significant positive association with infant DHEA levels (ß= 0.77 95% CI: 0.08, 1.47). Depression severity and chronicity at one year postpartum had near significant associations with infant DHEA. Measures of home environment had no observable impacts on infant HPA axis activity.

LIMITATIONS

Limitations include the modest sample size and aggregation of hair samples for analysis.

CONCLUSION

Results point to possible early HPA axis dysregulation driven by changes in DHEA activity, but not cortisol at one year of age. Findings contribute to growing research examining intergenerational transmissions of maternal depression, IPV, and household environment on infant stress-response systems.

Effectiveness of a peer-delivered, psychosocial intervention on maternal depression and child development at 3 years postnatal: a cluster randomised trial in Pakistan

BACKGROUND

Maternal depression has a recurring course that can influence offspring outcomes. Evidence on how to treat maternal depression to improve longer-term maternal outcomes and reduce intergenerational transmission of psychopathology is scarce, particularly for task-shifted, low-intensity, and scalable psychosocial interventions. We evaluated the effects of a peer-delivered, psychosocial intervention on maternal depression and child development at 3 years postnatal.

METHODS

40 village clusters in Pakistan were randomly allocated using a computerised randomisation sequence to receive a group-based, psychosocial intervention and enhanced usual care for 36 months, or enhanced usual care alone. Pregnant women (≥18 years) were screened for moderate or severe symptoms of depression (patient health questionnaire-9 [PHQ-9] score ≥10) and were recruited into the trial (570 participants), and a cohort without depression (PHQ-9 score <10) was also enrolled (584 participants). Including the non-depressed dyads enabled us to determine how much of the excess risk due to maternal depression exposure the intervention could mitigate. Research teams responsible for identifying, obtaining consent, and recruiting trial participants were blind to the allocation status throughout the duration of the study, and principal investigators, site coordinators, statisticians, and members of the trial steering committee were also blinded to the allocation status until the analysis of 6-month data for the intervention. Primary outcomes were maternal depression symptoms and remission (PHQ-9 score <10) and child socioemotional skills (strengths and difficulties questionnaire [SDQ-TD]) at 36-months postnatal. Analyses were by intention to treat. This trial is registered with ClinicalTrials.gov, NCT02658994.

FINDINGS

From Oct 15, 2014 to Feb 25, 2016 46 village clusters were assessed for eligibility, of which 40 (including 1910 mothers were enrolled. After exclusions, 288 women were randomly assigned to the enhanced usual care group and 284 to the intervention group, and 1159 women were included in a group without prenatal depression. At 36-months postnatal, complete data were available from 889 mother-child dyads: 206 (72·5%) in the intervention group, 216 (75·3%) in the enhanced usual care group, and 467 (80·0%) women who did not have prenatal-depression. We did not observe significant outcome differences between the intervention group and the enhanced usual care group for the primary outcomes. The standardised mean difference of PHQ-9 total score was -0·13 (95% CI -0·33 to 0·07), relative risk of patient health questionnaire-9 remission was 1·00 (95% CI 0·88 to 1·14), and the SDQ-TD treatment estimate was -0·10 (95% CI -1·39 to 1·19).

INTERPRETATION

Reduced symptom severity and high remission rates were seen across both the intervention and enhanced usual care groups, possibly masking any effects of the intervention. A multi-year, psychosocial intervention can be task-shifted via peers but might be susceptible to reductions in fidelity and dosage over time (which were not among the outcomes of this trial). Early intervention efforts might need to rely on multiple models (eg, collaborative care), be of greater intensity, and potentially targeted at mothers who are at high risk for depression to reduce the intergenerational transmission of psychopathology from mothers to children.

The contribution of grandmother involvement to child growth and development: an observational study in rural Pakistan

INTRODUCTION

Early childhood interventions primarily focus on the mother-child relationship, but grandmothers are often critical in childcare in low-resource settings. Prior research is mixed on how grandmother involvement influences child outcomes and there is a paucity of research on grandmother caregiving in low-income and middle-income countries. We examined the role of grandmother involvement on child growth and development in the first 2 years of life cross sectionally and longitudinally in rural Pakistan.

METHODS

We used data from the Bachpan Cohort, a longitudinal birth cohort in rural Pakistan. Maternally reported grandmother involvement in daily instrumental and non-instrumental caregiving was collected at 3 and 12 months. A summed score was created and categorised into non-involved, low and high. Outcomes included 12-month and 24-month child growth, 12-month Bayley Scales of Infant and Toddler Development and 24-month Ages and Stages Questionnaire-Socioemotional. We used multivariable generalised linear models to estimate mean differences (MD) at 12 months (n=727) and 24 months (n=712). Inverse probability weighting was used to account for missingness and sampling.

RESULTS

In our sample, 68% of children lived with a grandmother, and most grandmothers were involved in caregiving. Greater 3-month grandmother involvement was positively associated with 12-month weight z-scores; however, greater involvement was associated with lower 24-month weight z-scores. High 12-month grandmother involvement was associated with improved 12-month cognitive (MD=0.38, 95% CI -0.01 to 0.76), fine motor skills (MD=0.45, 95% CI 0.08 to 0.83) and 24-month socioemotional development (MD=-17.83, 95% CI -31.47 to -4.19). No meaningful associations were found for length z-scores or language development.

CONCLUSION

In rural Pakistan, grandmothers provide caregiving that influences early child development. Our findings highlight the complex relationship between grandmother involvement and child weight, and suggest that grandmothers may positively promote early child cognitive, fine motor and socioemotional development. Understanding how grandmother involvement affects child outcomes in early life is necessary to inform caregiving interventions.

The impact of an integrated depression and HIV treatment program on mental health and HIV care outcomes among people newly initiating antiretroviral therapy in Malawi

BACKGROUND

Depression is highly prevalent among patients newly starting antiretroviral treatment (ART) in Malawi and many other countries. Untreated depression at ART initiation can disrupt the HIV care continuum. Effective approaches for depression screening and treatment exist for low-resource settings, but they are rarely applied. Identifying effective implementation strategies are critical.

METHODS

A pilot program integrated depression screening and treatment into routine HIV care using existing staff at two public health clinics in Malawi in two phases; a screening-only "control" phase and an active "intervention" phase. During the intervention phase, providers prescribed antidepressants or referred patients for Friendship Bench problem-solving therapy. We evaluated the program's impact on retention in HIV care, viral suppression, and depression remission at 6 months using tabular comparisons and log-binomial models to estimate adjusted risk ratios and mean differences among the intervention group relative to the control group.

RESULTS

Nearly all consenting participants were screened for depression appropriately and 25% had mild to severe depressive symptoms. During the intervention phase, 86% of participants with mild depressive symptoms started Friendship Bench therapy and 96% of participants with moderate to severe depressive symptoms started antidepressants. Few participants in the intervention group received consistent depression treatment over their first 6 months in care. In the adjusted main analysis, program exposure did not demonstrably affect most HIV or mental health outcomes, though the probability of currently being on ART at 6 months was significantly lower among the intervention group than the control group [RR 0.6(95%CI: 0.4-0.9)].

CONCLUSIONS

While it is feasible to integrate depression screening and treatment initiation into ART initiation, providing ongoing depression treatment over time is challenging. Similar implementation science studies focused on maintaining depression management will be increasingly important as we strive to understand and test the best ways to implement evidence-based depression treatment within HIV care.

Associations among experienced and internalized stigma, social support, and depression among male and female sex workers in Kenya

OBJECTIVES

This study (1) estimated the association between experienced sex work-related stigma and moderate-to-severe depressive symptoms (hereafter depression), (2) examined independent associations between internalized stigma, experienced stigma, and depression among sex workers, and (3) investigated the potential modifying role of social support.

METHODS

A cross-sectional survey was conducted among 729 male and female sex workers in Kenya.

RESULTS

The prevalence of depression was 33.9%, and nearly all participants reported at least one of the experienced and internalized stigma items. Increasing levels of experienced stigma was associated with an increased predicted prevalence of depression [aPD 0.15 (95% CI 0.11-0.18)]. Increasing internalized stigma was independently associated with higher experienced stigma and depression and appeared to account for 25.5% of the shared variance between experienced stigma and depression after adjustment for confounders. Social support from same-sex sex workers did not appear to modify the association between experienced stigma and depression.

CONCLUSIONS

Addressing the high levels of stigma that sex workers face and their mental health needs should be a public health and human rights imperative.

Maternal depression in rural Pakistan: the protective associations with cultural postpartum practices

BACKGROUND

Traditional postpartum practices are intended to provide care to mothers, but there is mixed evidence concerning their impact on postpartum depression (PPD). It remains unknown if there is a unique impact of postpartum practices on PPD separately from other types of social support, or if practices differentially affect those with existing prenatal depression. In Pakistan, chilla (چله) is a traditional postpartum practice in which women receive relief from household work, additional familial support, and supplemental food for up to 40 days postpartum. This study aims to understand if chilla protects against PPD independent of other support and whether this relationship varies by prenatal depression status.

METHODS

Data come from the Bachpan cohort study in rural Pakistan. Chilla participation and social support (Multidimensional Scale of Perceived Social Support) were assessed at 3 months postpartum. Women were assessed for major depressive episodes (MDE) with the Structured Clinical Interview, DSM-IV and for depression symptom severity with the Patient Health Questionnaire (PHQ-9) in their third trimester and at 6 months postpartum. Adjusted linear mixed models were used to assess the relationship between chilla participation and PPD.

RESULTS

Eighty-nine percent of women (N = 786) participated in chilla and almost 70% of those that participated took part in all of chilla's aspects. In adjusted models, chilla participation was inversely related to MDE (OR = 0.56;95%CI = 0.31,1.03) and symptom severity (Mean Difference (MD) = - 1.54;95%CI: - 2.94,-0.14). Chilla participation was associated with lower odds of MDE (OR = 0.44;95%CI = 0.20,0.97) among those not prenatally depressed and with lower symptom severity among those prenatally depressed (MD = -2.05;95%CI:-3.81,-0.49).

CONCLUSIONS

Chilla is inversely associated with both MDE and symptom severity at 6 months postpartum above and beyond social support. Specifically, chilla is inversely associated with MDE among those not prenatally depressed and with lower symptom severity among those prenatally depressed. This relationship signals an opportunity for interventions aimed at preventing and treating PPD in this region to draw upon chilla and similar traditional postpartum practices in creating community-based, low-cost, sustainable interventions for maternal mental health.

Growth and form of a self-constructing tube network

When a small amount of liquid is quickly injected into another liquid with similar density, the fluid jet usually does not propagate very far. However, when the two solutions chemically react to form a flexible membrane at their interface, then structures that are long and branching can form. Here, we describe the tube networks produced when a small amount of AlCl₃ solution is quickly injected into a NaOH solution. Single straight tubes do not occur, but straight tubular "stems" with 2-5 "branches" are observed. The branches emerge relatively symmetrically from the stem at a common branching junction. These structures can have a ratio of propagation distance to stem width as large as 50. The stem and branches grow by the stretching of the membrane sheathing the closed tube system. These tube networks occasionally exhibit the spontaneous creation of new branches at a junction and also the splitting of a branching junction. A model explains why the branches occur, why they are symmetric around the central stem, and why the initial growth speed is insensitive to the flow rate.

Psychosocial determinants of sustained maternal functional impairment: Longitudinal findings from a pregnancy-birth cohort study in rural Pakistan

Function is an important marker of health throughout the life course, however, in low-and-middle-income-countries, little is known about the burden of functional impairment as women transition from pregnancy to the first year post-partum. Leveraging longitudinal data from 960 women participating in the Share Child Cohort in Pakistan, this study sought to (1) characterize functional trajectories over time among women in their perinatal period and (2) assess predictors of chronic poor functioning following childbirth. We used a group-based trajectory modeling approach to examine maternal patterns of function from the third trimester of pregnancy through 12 months post-partum. Three trajectory groups were found: persistently well-functioning (51% of women), poor functioning with recovery (39% of women), and chronically poor functioning (10% of women). When compared to mothers in the highest functioning group, psychosocial characteristics (e.g., depression, stress, and serious life events) were significantly associated with sustained poor functioning one-year following child-birth. Mothers living in nuclear households were more likely to experience chronic poor functioning. Higher education independently predicted maternal function recovery, even when controlling for psychosocial characteristics. Education, above and beyond socio-economic assets, appears to play an important protective role in maternal functional trajectories following childbirth. Public health implications related to maternal function and perinatal mental health are discussed.

A Novel Adaptation of the HOME Inventory for Elders: The Importance of the Home Environment Across the Life Course

The context in which dependents, regardless of age, receive care affects their health. This study adapted the Home Observation for Measurement of the Environment (HOME) Inventory, originally designed for child development research, to assess the quality of stimulation and support available to elders in their habitual households in Sri Lanka. Whether the adapted domains correlated with indicators of health and well-being in ways consistent with the child development literature was then examined. Through mixed-methods research based on 248 household surveys, four focus groups, and 15 interviews, three domains emerged: Physical Environment, Variety of Stimulation, and Emotional and Verbal Responsiveness. Regression modeling revealed that a higher quality physical home environment correlated with two measures of cognitive function after adjusting for covariates, but no consistent association with two psychological well-being scales. In contrast, higher Variety of Stimulation scores correlated with better cognitive function and lower psychological distress. There was no consistent correlation between Responsiveness and selected health outcomes. Qualitative data indicate that elders are active household contributors who strive to achieve harmonious relations with coresident kin. These findings reveal notable synergies between early and late life efforts to improve cognitive and psychological health, and highlight household considerations for future healthy aging research.

Cohort Profile: Perinatal depression and child socioemotional development ; the Bachpan cohort study from rural Pakistan

PURPOSE

This is a prospective pregnancy-birth cohort designed to investigate the effects of depression on socioemotional development of children. Perinatal depression is a risk factor for poor child development and for many it has a recurring chronic course. Thus, the exposure to depression can continue through the early years of the child with detrimental developmental outcomes.

PARTICIPANTS

Between October 2014 and February 2016, we recruited 1154 pregnant women from a rural subdistrict of Pakistan. Data include longitudinal and repeated measures of maternal psychosocial measures and child growth, cognitive and socioemotional measures. Follow-up include mother-child dyad assessments at 3rd, 6th, 12th, 24th and 36th months of child age. All these follow-ups are community based at the household level. We have competed baseline assessment.

FINDINGS TO DATE

Of the eligible dyads, we followed 885 (76.6%), 929 (91%) and 940 (93.3%) at 3, 6 and 12 months post-childbirth. We include a subsample mother-child dyad DNA and inflammatory biomarkers, 73 and 104, respectively.

FUTURE PLANS

While we continue to do 24-month and 36-month follow-up assessments, we plan to follow these mother-child dyads up to the age of 7-8 years with some children being exposed to at least 1 year of school environment. Investigators interested in learning more about the study can contact (jmaselko@unc.edu) and (siham.sikander@hdrfoundation.org).

The relationship between responsive caregiving and child outcomes: evidence from direct observations of mother-child dyads in Pakistan

Background

Responsive caregiving, or interactions in which caregivers give appropriate responses to a child’s signals, is linked to improved psychosocial, cognitive and physical outcomes in children. However, much remains unknown about how responsive caregiving affects child development across cultural and socioeconomic contexts. The purpose of this study is to examine predictors of maternal responsive caregiving and investigate how these interactions are associated with children’s development.

Methods

Data for the current analyses came from a longitudinal study designed to follow mothers from the third trimester through the first three years of the child’s life. To assess responsive caregiving, the Observation of Mother-Child Interaction (OMCI) measure was used to examine maternal and child behaviors during a 5-min picture book activity at 24 months. Outcomes included child height-for-age z-score and child socioemotional development, using the Ages and Stages Questionnaire-Socioemotional (ASQ-SE) in which lower scores demonstrated better development. Using mean comparisons, the effects of baseline sociodemographic factors and maternal depression on responsive caregiving were tested. Analyses utilized hierarchical linear regressions to examine cross-sectional associations between responsive caregiving and child development outcomes at 24 months. Additional analyses controlled for the Home Observation for Measurement of the Environment (HOME), a common measure in low-income contexts of caregiving, to assess whether OMCI was uniquely predictive of child outcomes.

Results

Higher maternal education attainment, lower number of children, greater socioeconomic assets, and lack of maternal depression were associated with higher levels of observed responsive caregiving behaviors. Higher total OMCI scores were associated with positive child socioemotional outcomes in adjusted models (β: -0.84, 95% CI [− 1.40, − 0.29]). The finding was statistically significant, even after controlling for HOME score (β: -0.83, 95% CI [− 1.38, − 0.27]). There was no association between OMCI scores and child linear growth.

Conclusions

Responsive caregiving is linked to positive child socioemotional development in rural Pakistan. Our findings suggest that incorporating responsive caregiving into child health interventions in LMIC may have valuable impacts on child socioemotional development. The OMCI may be useful in identifying important pathways for change to responsive caregiving behaviors and may be of service for future interventions that optimize child development through responsive caregiving.

Delivering maternal mental health through peer volunteers: a 5-year report

BACKGROUND

Maternal depression affects one in five women in low-and middle income countries (LMIC) and has significant economic and social impacts. Evidence-based psychosocial interventions delivered by non-specialist health workers are recommended as first-line management of the condition, and recent studies on such interventions from LMIC show promising results. However, lack of human resource to deliver the interventions is a major bottle-neck to scale-up, and much research attention has been devoted to 'task-sharing' initiatives. A peer-delivered version of the World Health Organization's Thinking Healthy Programme for perinatal depression in Pakistan and India showed clinical, functional and social benefits to women at 3 months postpartum. The programme has been iteratively adapted and continually delivered for 5 years in Pakistan. In this report, we describe the extended intervention and factors contributing to the peers' continued motivation and retention, and suggest future directions to address scale-up challenges.

METHODS

The study was conducted in rural Rawalpindi. We used mixed methods to evaluate the programme 5 years since its initiation. The competency of the peers in delivering the intervention was evaluated using a specially developed Quality and Competency Checklist, an observational tool used by trainers to rate a group session on key areas of competencies. In-depth interviews explored factors contributing to the peer volunteers' continued motivation and retention, as well as the key challenges faced.

RESULTS

Our key findings are that about 70% of the peer volunteers inducted 5 years ago continued to be part of the programme, retaining their competency in delivering the intervention, with only token financial incentives. Factors contributing to sustained motivation included altruistic aspirations, enhanced social standing in the community, personal benefits to their own mental health, and the possibility for other avenues of employment. Long-term challenges included demotivation due to lack of certainty about the programme's future, increased requirement for financial incentivisation, the logistics of organising groups in the community, and resistance from some families to the need for ongoing care.

CONCLUSIONS

The programme, given the sustained motivation and competence of peer volunteers in delivering the intervention, has the potential for long-term sustainability in under-resourced settings and a candidate for scale-up.

Prevalence and factors associated with antenatal depressive symptoms among women enrolled in Option B+ antenatal HIV care in Malawi: a cross-sectional analysis

BACKGROUND

Option B+ has increased the number of pregnant women initiating antiretroviral therapy for HIV, yet retention in HIV care is sub-optimal. Retention may be affected by antenatal depression. However, few data exist on antenatal depression in this population.

AIM

Describe the prevalence and factors associated with antenatal depression among Malawian women enrolled in Option B+.

METHOD

At their first antenatal visit, women with HIV provided demographic and psychosocial information, including depression as measured with the locally validated Edinburgh Postnatal Depression Scale (EPDS). Prevalence ratios (PR) for factors associated with probable depression (EPDS ≥6) were estimated with log binomial regression.

RESULTS

9.5% (95% CI: 7.5-11.9%) of women screened positive for current depression, and 46% self-reported a history of depression or anxiety. Women were more likely to screen positive for current depression if they reported a history of depression (adjusted PR: 2.42; 95% CI: 1.48-3.95) or had ever experienced intimate partner violence (1.77; 1.11-2.81). Having an unintended current pregnancy (1.78; 0.99-3.21), being unmarried (1.66; 0.97-2.84), or employed (1.56; 1.00-2.44) had potential associations with probable depression.

CONCLUSIONS

Probable antenatal depression affected a notable proportion of women living with HIV, comparable to other global regions. Screening for antenatal depression in HIV care should be considered.

Neighborhood language isolation and depressive symptoms among elderly U.S. Latinos

PURPOSE

Neighborhood segregation related to cultural factors, such as language use, may influence elderly Latino depression. We examined the association between neighborhood-level Spanish language segregation and individual depressive symptoms among elderly Latinos.

METHODS

We linked U.S. Census language use data with geocoded population-based data from 1789 elderly Latinos (mean age = 70.6 years) participating in the Sacramento Area Latino Study on Aging (1998-2008). Neighborhood language segregation was measured with the Index of Concentration at the Extremes, which demonstrates the extent to which residents are concentrated at extremes of deprivation and privilege. We fit two-level generalized linear-mixed models with random intercepts for census tracts to quantify the association between neighborhood-level language segregation and depressive symptoms, adjusting for identified confounders.

RESULTS

After adjusting for age, sex, and nativity, residents of highly segregated Spanish-speaking neighborhoods had more depressive symptoms than those in highly segregated English-only-speaking neighborhoods (β = -4.410; 95% confidence interval [CI] = -6.851 to -1.970). This association was largely attenuated upon adjustment for individual-level education (β = -2.119; 95% CI = -4.650 to 0.413).

CONCLUSIONS

Linguistically segregated communities may benefit from targeted outreach given the high depression prevalence in these neighborhoods. Furthermore, our findings suggest that limited access to fundamental social protections, such as education, may drive the segregation-depression association among U.S. Latinos.

Educational Mobility Across Generations and Depressive Symptoms Over 10 Years Among US Latinos

Few studies have collected intergenerational data to assess the association between educational mobility across multiple generations and offspring depression. Using data from the Sacramento Area Latino Study on Aging (1998-2008), we assessed the influence of intergenerational education on depressive symptoms over 10 years among 1,786 Latino individuals (mean age = 70.6 years). Educational mobility was classified as stable-low (low parental/low offspring education), upwardly mobile (low parental/high offspring education), stable-high (high parental/high offspring education), or downwardly mobile (high parental/low offspring education). Depressive symptoms were measured with the Center for Epidemiological Studies-Depression Scale (CES-D); higher scores indicated more depressive symptoms. To quantify the association between educational mobility and CES-D scores over follow-up, we used generalized estimating equations to account for repeated CES-D measurements and adjusted for identified confounders. Within individuals, depressive symptoms remained relatively stable over follow-up. Compared with stable-low education, stable-high education and upward mobility were associated with significantly lower CES-D scores (β = -2.75 and -2.18, respectively). Downwardly mobile participants had slightly lower CES-D scores than stable-low participants (β = -0.77). Our results suggest that sustained, low educational attainment across generations may have adverse mental health consequences, and improved educational opportunities in underresourced communities may counteract the adverse influence of low parental education on Latino depression.

Criterion-related validity and reliability of the Urdu version of the patient health questionnaire in a sample of community-based pregnant women in Pakistan

Background

Depression is one of the most prevalent, yet unrecognized but treatable mental disorders in low and middle income countries (LMICs). In such locations, screening tools that are easy-to-administer, valid, and reliable are needed to assist in detecting symptoms of depression. The Patient Health Questionnaire (PHQ-9) is one of the most widely used depression screeners. However, its applicability to community-based settings of Pakistan is limited by the lack of studies examining its validity and reliability in such settings. The current study aimed to demonstrate the criterion-related validity and internal reliability of the Urdu version of the PHQ-9 in a sample of community-based pregnant women in Pakistan compared to a diagnostic clinical interview, the Structured Clinical Interview for DSM disorders (SCID), using data from a depression treatment cluster randomized trial in rural Pakistan.

Methods

Pregnant women in a rural, low income sub-district in Pakistan were approached between October 2014 and February 2016 and, after providing informed consent, screened for depression using the Urdu version of the PHQ-9, with a cutoff of ≥10 used to indicate significant depressive symptoms. Following the PHQ-9, the diagnostic module for current major depressive episode of the SCID was administered. We examined the psychometric properties of PHQ-9 compared to SCID as a gold standard, using sensitivity, specificity, and negative and positive predictive value to measure the criterion-related validity of the PHQ-9 as an indicator of symptoms of depression. We computed area under the receiver operating characteristic curve to determine diagnostic accuracy, and used Cronbach’s alpha to assess internal reliability.

Results

A total of 1,731 women in their third trimester of pregnancy were assessed for major depressive disorder. Of these women, 572 (33%) met the cutoff for significant depressive symptoms on PHQ-9, and 454 (26%) were assessed positive for depression using the SCID. The sensitivity and specificity of PHQ-9 at a cutoff of ≥10 was 94.7% and 88.9%, respectively. The positive and negative predictive values were 75.2% and 97.9%, respectively; and the area under the curve was 0.959. Internal reliability, as measured by Cronbach’s alpha, was 0.844.

Discussion

Valid and reliable screening tools to assist in detecting symptoms of depressive disorder are needed in low income settings where depressive disorders are highly prevalent. The Urdu version of the PHQ-9 has not been previously validated against a well-known assessment of depression in a community setting among pregnant women in Pakistan. This study demonstrates that the Urdu version of the PHQ-9 has acceptable criterion-related validity and reliability for screening for depressive symptoms in Pakistan among community-based pregnant women; and when the recommended cut-off score of ≥10 is used it can also serve as an accurate screening tool for major depressive disorder.

Generativity Among Elderly in a Rural Area of Maharashtra, India: Correlates and Relationship With Quality of Life Approved

Generativity, "a concern for others and a need to contribute something to the next generation," is a dimension of successful aging in and of itself, but also predicts other positive health outcomes. We examine its manifestations and correlates among elderly in rural India and assess the association between generativity and quality of life (QoL). Three hundred and forty-eight rural Indian elderly completed an interviewer-assisted questionnaire assessing generativity, QoL, and other personal and familial factors. Regression models were used to examine potential correlates of generativity and the relationship between generativity and QoL. Higher education, inheritance income, more living children, and a son/daughter living in the home predicted higher levels of generativity. Higher levels of generativity were associated with higher QoL. There are both personal and familial correlates of generativity, and family relationships are important for generative development. Family-oriented interventions to increase generativity among elderly Indians could improve QoL.

Socioeconomic status indicators and common mental disorders: Evidence from a study of prenatal depression in Pakistan

There is growing interest in the relationship between socioeconomic status (SES), poverty, and mental health in low and middle-income countries (LMIC). However, it is not clear whether a gradient approach focused on a wider SES distribution or a binary poverty approach is more salient for mental health in LMIC. Yet this distinction has implications for interventions aimed at improving population health. We contribute to the literature by examining how multiple indicators of socioeconomic status, including gradient SES and binary poverty indicators, contribute to prenatal depression symptoms in a LMIC context. Prenatal depression is an important public health concern with negative sequela for the mother and her children. We use data on assets, education, food insecurity, debt, and depression symptoms from a sample of 1154 pregnant women residing in rural Pakistan. Women who screened positive for depression participated in a cluster randomized controlled trial of a perinatal depression intervention; all women were interviewed October 2015-February 2016, prior to the start of the intervention. Cluster-specific sampling weights were used to approximate a random sample of pregnant women in the area. Findings indicate that fewer assets, experiencing food insecurity, and having household debt are independently associated with worse depression symptoms. The association with assets is linear with no evidence of a threshold effect, supporting the idea of a gradient in the association between levels of SES and depression symptoms. A gradient was also initially observed with woman’s educational attainment, but this association was attenuated once other SES variables were included in the model. Together, the asset, food insecurity, and debt indicators explain 14% of the variance in depression symptoms, more than has been reported in high income country studies. These findings support the use of multiple SES indicators to better elucidate the complex relationship between socioeconomic status and mental health in LMIC.

•

We compare the association between poverty, gradient measures of SES, and depression.

•

Above the poverty level, SES predict depression in a low income country.

•

Relying on simple, dichotomous, poverty measures in studies of mental health is not recommended.

Social Epidemiology and Global Mental Health: Expanding the Evidence from High-Income to Low- and Middle-Income Countries

PURPOSE OF THE REVIEW

The vast majority of research on the social determinants of mental health has been generated from high-income country (HIC) populations, even as the greatest health disparities, and greatest disease burden, is observed in lower- and middle-income countries (LMICs). The goal of this review is to examine the evidence base on how key social epidemiology constructs relate to mental health in LMIC contexts. A special focus is on points of departure from the HIC knowledge base, gaps in overall understanding, and opportunities for social epidemiology to make a significant contribution.

RECENT FINDINGS

A growing body of literature suggests that there is significant heterogeneity, both in the direction and magnitude, of association between factors such as socioeconomic status, income inequality, gender, and social networks/supports and mental health in LMIC. For example, higher levels of education and being married can be risk factors for worse mental health among women in certain contexts. However, many studies have methodological limitations that make causal inference difficult. Poverty alleviation interventions offer a unique opportunity to examine the impact of improving economic resources and mental health.

SUMMARY

Much remains unknown about the impact of key social factors on mental health in LMIC. Findings from HICs may not apply to LMIC populations, since the meaning and distribution of a given social variable may differ significantly from what is commonly observed in HICs. These points of departure point to opportunities for social epidemiology to make a contribution to the field of global mental health.

The effectiveness of Technology-assisted Cascade Training and Supervision of community health workers in delivering the Thinking Healthy Program for perinatal depression in a post-conflict area of Pakistan - study protocol for a randomized controlled trial

BACKGROUND

Rates of perinatal depression in low and middle income countries are reported to be very high. Perinatal depression not only has profound impact on women's health, disability and functioning, it is associated with poor child health outcomes such as pre-term birth, under-nutrition and stunting, which ultimately have an adverse trans-generational impact. There is strong evidence in the medical literature that perinatal depression can be effectively managed with psychological treatments delivered by non-specialists. Our previous research in Pakistan led to the development of a successful perinatal depression intervention, the Thinking Healthy Program (THP). The THP is a psychological treatment delivered by community health workers. The burden of perinatal depression can be reduced through scale-up of this proven intervention; however, training of health workers at scale is a major barrier. To enhance access to such interventions there is a need to look at technological solutions to training and supervision.

METHODS/DESIGN

This is a non-inferiority, single-blinded randomized controlled trial. Eighty community health workers called Lady Health Workers (LHWs) working in a post-conflict rural area in Pakistan (Swat) will be recruited through the LHW program. LHWs will be randomly allocated to Technology-assisted Cascade Training and Supervision (TACTS) or to specialist-delivered training (40 in each group). The TACTS group will receive training in THP through LHW supervisors using a tablet-based training package, whereas the comparison group will receive training directly from mental health specialists. Our hypothesis is that both groups will achieve equal competence. Primary outcome measure will be competence of health workers at delivering THP using a modified ENhancing Assessment of Common Therapeutic factors (ENACT) rating scale immediately post training and after 3 months of supervision. Independent assessors will be blinded to the LHW allocation status.

DISCUSSION

Women living in post-conflict areas are at higher risk of depression compared to the general population. Implementation of evidence-based interventions for depression in such situations is a challenge because health systems are weak and human resources are scarce. The key innovation to be tested in this trial is a Technology-assisted Cascade Training and Supervision system to assist scale-up of the THP.
