Depressive Symptoms Prior to Pregnancy and Infant Low Birth Weight in South Africa

Perinatal Depressive Symptoms and Viral Non-suppression Among a Prospective Cohort of Pregnant Women Living with HIV in Nigeria, Kenya, Uganda, and Tanzania

Depression is common during pregnancy and is associated with reduced adherence to HIV-related care, though little is known about perinatal trajectories of depression and viral suppression among women living with HIV (WLHV) in sub-Saharan Africa. We sought to assess any association between perinatal depressive symptoms and viral non-suppression among WLWH. Depressive symptomatology and viral load data were collected every 6 months from WLWH enrolled in the African Cohort Study (AFRICOS; January 2013-February 2020). Generalized estimating equations modeled associations between depressive symptoms [Center for Epidemiological Studies Depression (CES-D) ≥ 16] and viral non-suppression. Of 1722 WLWH, 248 (14.4%) had at least one pregnancy (291 total) and for 61 pregnancies (21.0%), women reported depressive symptoms (13.4% pre-conception, 7.6% pregnancy, 5.5% one-year postpartum). Depressive symptomatology was associated with increased odds of viral non-suppression (aOR 2.2; 95% CI 1.2-4.0, p = 0.011). Identification and treatment of depression among women with HIV may improve HIV outcomes for mothers.

Increased urban greenness associated with improved mental health among middle-aged and older adults of the Canadian Longitudinal Study on Aging (CLSA)

OBJECTIVES

Some studies suggest that residential surrounding greenness is associated with improved mental health. Few of these studies have focussed on middle-aged and older adults, explored the modifying effects of social determinants of health, or accounted for the extent to which individuals interact with their neighbourhood environments.

METHODS

We analysed cross-sectional data collected from 26,811 urban participants of the Canadian Longitudinal Study of Aging who were between 45 and 86 years of age. Participants provided details on socioeconomic characteristics, health behaviours, and their frequency of neighbourhood interactions. The Normalized Difference Vegetation Index (NDVI), a measure of greenness, was assigned to participants' residential addresses at a buffer distance of 500 m. Four self-reported measures of mental health were considered: The Center for Epidemiologic Studies Depression Scale (CES-D-10; short scale), past diagnosis of clinical depression, perceptions of mental health, and the Satisfaction with Life Scale (SWLS). Regression models were used to describe associations between greenness and these outcomes, and spline models were fit to characterize the exposure-response function between greenness and CES-D-10 scores. Stratified analyses evaluated whether associations varied by sociodemographic status.

RESULTS

In adjusted models, we observed a 5% (Odds Ratio (OR) = 0.95; 95% CI = 0.90, 0.99) reduced odds of depressive symptoms in relation to an interquartile range increase of NDVI (0.06) within a 500 m buffer of the participant's residence. Similarly, we found an inverse association with a self-reported clinical diagnosis of depression (OR = 0.97; 95% CI = 0.92-1.01). Increases in surrounding greenness were associated with improved perceptions of mental health, and the SWLS. Our spline analyses found that beneficial effects between greenness and the CES-D-10 were strongest among those of lower income.

CONCLUSIONS

These findings suggest that residential greenness has mental health benefits, and that interventions to increase urban greenness can help reduce social inequalities in mental health.

Antenatal Depression as a Stunting Risk Factor: A Systematic Review

BACKGROUND: Depression during pregnancy is often found and ignored even though depression has a negative impact not only on the mother but also on the fetus to adulthood. Stunting is a problem of lack of nutritional status that begins during pregnancy. AIM: The purpose of this article is to systematically identify the description and relationship between depression during pregnancy and stunting in children. METHOD: The approach used is the systematic review method to search articles. Articles were identified from 2010-2020 by conducting a literature search with the keywords "antenatal depression" OR "prenatal depression" OR "depression during pregnancy" and "stunting" in the electronic databases dataset by Sciencedirect, Pubmed Research Gate, and Google Scholar. RESULTS: The search results found 1875 articles selected into 20 journal articles that match the inclusion criteria. CONCLUSION: The results found that depression during pregnancy correlated with risk factors for stunting. As a preventive measure, health workers, especially midwives, can provide psychological care in antenatal care by considering these factors.

Addressing maternal and child health equity through a community health worker home visiting intervention to reduce low birth weight: retrospective quasi-experimental study of the Arizona Health Start Programme

OBJECTIVE

To test if participation in the Health Start Programme, an Arizona statewide Community Health Worker (CHW) maternal and child health (MCH) home visiting programme, reduced rates of low birth weight (LBW), very LBW (VLBW), extremely LBW (ELBW) and preterm birth (PTB).

DESIGN

Quasi-experimental retrospective study using propensity score matching of Health Start Programme enrolment data to state birth certificate records for years 2006-2016.

SETTING

Arizona is uniquely racially and ethnically diverse with comparatively higher proportions of Latino and American Indian residents and a smaller proportion of African Americans.

PARTICIPANTS

7212 Health Start Programme mothers matched to non-participants based on demographic, socioeconomic and geographic characteristics, health conditions and previous birth experiences.

INTERVENTION

A statewide CHW MCH home visiting programme.

PRIMARY AND SECONDARY OUTCOME MEASURES

LBW, VLBW, ELBW and PTB.

RESULTS

Using Health Start Programme's administrative data and birth certificate data from 2006 to 2016, we identified 7212 Health Start Programme participants and 53 948 matches. Programme participation is associated with decreases in adverse birth outcomes for most subgroups. Health Start participation is associated with statistically significant lower rates of LBW among American Indian women (38%; average treatment-on-the-treated effect (ATT): 2.30; 95% CI -4.07 to -0.53) and mothers with a pre-existing health risk (25%; ATT: -3.06; 95% CI -5.82 to -0.30). Among Latina mothers, Health Start Programme participation is associated with statistically significant lower rates of VLBW (36%; ATT: 0.35; 95% CI -0.69 to -0.01) and ELBW (62%; ATT: 0.31; 95% CI (-0.52 to -0.10)). Finally, Health Start Programme participation is associated with a statistically significant lower rate of PTB for teen mothers (30%; ATT: 2.81; 95% CI -4.71 to -0.91). Other results were not statistically significant.

CONCLUSION

A state health department-operated MCH home visiting intervention that employs CHWs as the primary interventionist may contribute to the reduction of LBW, VLBW, ELBW and PTB and could improve birth outcomes statewide, especially among women and children at increased risk for MCH inequity.

Pre-existingmental health disorders affect pregnancy and neonatal outcomes: a retrospectivecohort study

BACKGROUND

This was a hospital registry-based retrospective age-matched cohort study that aimed to compare pregnancy and neonatal outcomes of women with pre-existing mental disorders with those of mentally healthy women.

METHODS

A matched cohort retrospective study was carried out in the Department of Obstetrics and Gynecology, Hospital of Lithuanian University of Health Sciences Kauno Klinikos, a tertiary health care institution. Medical records of pregnant women who gave birth from 2006 to 2015 were used. The study group was comprised of 131 pregnant women with mental disorders matched to 228 mentally healthy controls. The primary outcomes assessed were antenatal care characteristics; secondary outcomes were neonatal complications.

RESULTS

Pregnant women with pre-existing mental health disorders were significantly more likely to have low education, be unmarried and unemployed, have a disability that led to lower working capacity, smoke more frequently, have chronic concomitant diseases, attend fewer antenatal visits, gain less weight, be hospitalized during pregnancy, spend more time in hospital during the postpartum period, and were less likely to breastfeed their newborns. The newborns of women with pre-existing mental disorders were small for gestational age (SGA) more often than those of healthy controls (12.9% vs. 7.6%, p < 0.05). No difference was found comparing the methods of delivery.

CONCLUSIONS

Women with pre-existing mental health disorders had a worse course of pregnancy. Mental illness increased the risk to deliver a SGA newborn (RR 2.055, 95% CI 1.081-3.908).

The relationship between women's experience of intimate partner violence and other socio-demographic factors, and under-5 children's health in South Africa

Women in South Africa experience high levels of Intimate Partner Violence (IPV). There are numerous health consequences experienced by victims. However, children of IPV victims often experience negative emotional and developmental outcomes as well. In South Africa, infant and child health outcomes are not optimal and IPV is high, and thus there is a need to determine whether a relationship between them exists. This study used the 2016 South African Demographic and Health Survey. Mothers aged 15 to 49 and who were included in the Domestic Violence module formed the study population. Frequency tables and graphs were done, and unadjusted and adjusted logistic regressions were performed with each of the three reported child health outcomes (birth weight, duration of breastfeeding and diarrhoea incidence), IPV and other socio-demographic factors. Thirteen percent of women have experienced IPV. Five percent of their children were low birth weight, 10% had experienced diarrhoea; but 87% had been breastfed for 6+ months. Mothers in the rich wealth category were 37% more likely to have a child born at low birth weight but those aged 20 to 39 had around a 60% less likelihood of breastfeeding for 6+ months than 15 to 19-year olds. Women who had experienced IPV had around 77% higher odds of having a child experience diarrhoea in the last 2 weeks. Wealthier mothers often have unhealthier lifestyle practices and behaviours, due to more disposable income which could account for lower birth weight children. Mothers in tertiary education and starting their professional careers are normally around 20 to 39 years and should be provided supportive structures to be allowed to breastfeed their children. The long-term emotional and developmental consequences to children of IPV victims are known, but we now know that there are also very immediate consequences to the health of these children as well.

Perception of Mothers and Selected Informal Maternity Caregivers Regarding Maternal Depression in Two Communities of Ibadan In Nigeria

This article described the perception of young mothers and selected informal maternity caregivers with no known antecedents of depression residing in two communities in Ibadan, Nigeria about maternal depression. This study is qualitative in design. We purposively selected fifty-one pregnant women and nursing mothers (young mothers) within the communities and the clinics. Thirty-three informal caregivers (Community Birth attendants (CBAs), elderly mothers and men of reproductive age) were also selected. We utilized Focus Group Discussions (FGD), Key Informant Interviews (KIIs), open-ended interviews and document consultation to obtain information about maternal depression. Discussions and interviews were digitally recorded, transcribed verbatim and analyzed using thematic analysis with Nvivo version 15. Common phrases used to describe maternal depression were "severe worrying" and "chronic unhappiness". Young mothers opined that maternal depression was caused by lack of partner support while more of the men and elderly mothers felt spiritual causes were responsible. Symptoms of maternal depression described by the participants included prolonged loss of interest in pleasurable activities and being moody. Common consequences of maternal depression mentioned were premature onset of labour and low birth weight babies. The perceived help-seeking behaviour included special rituals and deliverance. CBAs mentioned referral to a psychiatrist as a last resort. Participants were aware of maternal depression and its symptoms, however, there were misconceptions about the causes which influenced the perceived help-seeking of elderly mothers and men. Health education interventions to dispel these misconceptions should therefore target the mothers and informal caregivers in the study area.

Screening for Antepartum Depression Through Community Health Outreach in Swaziland

Maternal depression, including antepartum and postpartum depression, is a neglected public health issue with potentially far-reaching effects on maternal and child health. We aimed to measure the burden of antepartum depression and identify risk factors among women in a peri-urban community in Swaziland. We conducted a cross-sectional study within the context of a community outreach peer support project involving "Mentor Mothers". We used of the Edinburgh Postnatal Depression Scale (EPDS) to screen women for depression during the third trimester of pregnancy, using a cut-off score of ≥13 to indicate depression. We also collected demographic and socioeconomic factors, and assessed the association of these factors with EPDS score using logistic regression models. A total of 1038 pregnant women were screened over a period of 9 months. Almost a quarter (22.7 %) had EPDS scores ≥13 and 41.2 % were HIV positive. A fifth, 17.5 % were teenagers and 73.7 % were unemployed. Depression was not associated with HIV status, age or employment status. However, women with multiple socioeconomic stressors were found to be more likely to score highly on the EPDS. Depression was common among pregnant women in the peri-urban areas of Swaziland. Screening for depression using the EPDS is feasible and can be included in the community health worker standard tool box as a way to improve early detection of depression and to highlight the importance of maternal mental health as a core public health concern.

Pre-pregnancy maternal depressive symptoms and low birth weight and preterm birth outcomes: Assessment of adolescent background characteristics and birth outcomes in adulthood

PURPOSE

In the United States and other countries of the world , high prevalence of pre-pregnancy depressive symptoms and depression during pregnancy is an important public health concern, as they are associated with low birth weight (LBW) and preterm birth (PTB) outcomes in adulthood. However, the relationships among pre-pregnancy depressive symptoms, low birth weight, preterm birth outcomes and household characteristics have not been well established.

METHODS

The study used data from 7120 adolescent female participants in the National Longitudinal Study of Adolescent to Adult Health data from Waves I (1994-1995 in-school interview), II (1996 as in-home), III (2001-2002 as in-home interview), IV (2008 as in-home interview) and Wave V is currently underway. The main outcomes were LBW and PTB. Maternal depressive symptoms were assessed with the Center for Epidemiologic Studies Depression scale (CES-D) using a cut-off point of 24 to indicate higher depressive symptoms . Odds ratios were used as an estimate of the relative risk using generalized estimating equations (GEE).

RESULTS

In Wave I, prevalence of depressive symptoms among age groups 11-15 (54.1%) was higher than older adolescents (45.9%) were. With the exception of depressive symptoms reported in Wave II, respondents reporting depressive symptoms in Waves I and III had similar unadjusted rates of LBW or PTB infants in adulthood. Mothers reporting higher depressive symptoms in older adolescence (15-19 years) had elevated odds of LBW infants (3.58 [95% CI=1.81, 7.09]) in Wave III compared with others reporting low depressive symptoms.

CONCLUSIONS

Undeniably, childhood socioeconomic circumstances are important determinants of disease risks and improved health functioning and in particular birth outcomes in adulthood. Since poorer households have fewer resources to cope with stressful events that generate mood and other depressive symptoms over the life course, findings of research suggest treating depressive symptoms prior to pregnancy will yield significant dividends for mothers and society. Furthermore, without careful control of household contexts, the association between depressive symptoms and birth outcomes is likely to be confounded.

High social trust associated with increased depressive symptoms in a longitudinal South African sample

Several studies have documented a protective association between social trust and mental and physical health, but gaps in knowledge remain. Debates regarding the contextual versus individual nature of social trust are ongoing; research from low- and middle-income countries is lacking, and study designs have been limited for causal inference. To address these gaps, we examined the association between social trust and depressive symptoms using three waves of the National Income Dynamics Study, a longitudinal South African survey. We used individual fixed-effects models to assess the association between changes in scores on the Center for Epidemiological Studies Depression Scale Short Form (CES-D-10) and in individual-level and district-level personalized and generalized trust among 15,670 individuals completing at least two waves of the NIDS adult questionnaire. High individual-level generalized trust was unexpectedly associated with increased depressive symptoms scores while district generalized trust did not show an association. We also found a cross-level interaction between individual and district-level personalized trust. High individual trust was associated with increased depressive symptoms scores when district trust was low; however, as district-level trust increased, higher individual trust was associated with reduced depressive symptoms. Our unexpected results suggest that trust may not always be beneficial for depressive symptoms, but rather, that its effects may depend on context. In the South African setting where social trust is low, being very likely to trust may be associated with worse depressive symptoms in some circumstances.

Mentor Mothers Program Improved Child Health Outcomes At A Relatively Low Cost In South Africa

In light of South Africa's high prenatal HIV prevalence and infant mortality rate, a cluster randomized controlled trial was conducted to evaluate an intervention called Philani+, which used community health workers (known as Mentor Mothers) to deliver pre- and postnatal home visits in Cape Town, South Africa, to improve maternal and child health. We assessed the costs and benefits of this intervention and made comparisons with other scenarios that depicted increased capacity and provision of nurse-delivered care. The recurrent cost of the twenty-four-month intervention was US$80,001. The major health outcomes analyzed were differences in the proportion of infants who were low birthweight, stunted, and suboptimally breastfed between intervention and control groups. Each case of low birthweight averted cost US$2,397; of stunted growth, US$2,454; and of suboptimal breastfeeding, US$1,618. Employment of community health workers was cost saving compared to that of nurses. Philani+ improved child health at a relatively low cost, considering the health system costs associated with low birthweight and undernutrition. The model could be suitable for replication in low-resource settings to improve child health in other countries.

Validation of the 10-item Centre for Epidemiological Studies Depression Scale (CES-D-10) in Zulu, Xhosa and Afrikaans populations in South Africa

BACKGROUND

The 10-item Centre for Epidemiological Studies Depression Scale (CES-D-10) is a depression screening tool that has been used in the South African National Income Dynamics Study (NIDS), a national household panel study. This screening tool has not yet been validated in South Africa. This study aimed to establish the reliability and validity of the CES-D-10 in Zulu, Xhosa and Afrikaans. The CES-D-10's psychometric properties were also compared to the Patient Health Questionnaire (PHQ-9), a depression screening tool already validated in South Africa.

METHODS

Stratified random samples of Xhosa, Afrikaans and Zulu-speaking participants aged 15 years or older (N = 944) were recruited from Cape Town Metro and Ethekwini districts. Face-to-face interviews included socio-demographic questions, the CES-D-10, Patient Health Questionnaire (PHQ-9), and WHO Disability Assessment Schedule 2.0 (WHODAS). Major depression was determined using the Mini International Neuropsychiatric Interview. All instruments were translated and back-translated to English. Construct validity was examined using exploratory factor analysis with varimax rotation. Receiver Operating Characteristics (ROC) curves were used to investigate the CES-D-10 and PHQ-9's criterion validity, and compared using the DeLong method.

RESULTS

Overall, 6.6, 18.0 and 6.9% of the Zulu, Afrikaans and Xhosa samples were diagnosed with depression, respectively. The CES-D-10 had acceptable internal consistency across samples (α = 0.69-0.89), and adequate concurrent validity, when compared to the PHQ-9 and WHODAS. The CES-D-10 area under the Receiver Operator Characteristic curve was good to excellent: 0.81 (95% CI 0.71-0.90) for Zulu, 0.93 (95% CI 0.90-0.96) for Afrikaans, and 0.94 (95% CI 0.89-0.99) for Xhosa. A cut-off of 12, 11 and 13 for Zulu, Afrikaans and Xhosa, respectively, generated the most balanced sensitivity, specificity and positive predictive value (Zulu: 71.4, 72.6% and 16.1%; Afrikaans: 84.6%, 84.0%, 53.7%; Xhosa: 81.0%, 95.0%, 54.8%). These were slightly higher than those generated for the PHQ-9. The CES-D-10 and PHQ-9 otherwise performed similarly across samples.

CONCLUSIONS

The CES-D-10 is a valid, reliable screening tool for depression in Zulu, Xhosa and coloured Afrikaans populations.

Role of Mediators in Reducing Antepartum Depressive Symptoms in Rural Low-Income Women Receiving a Culturally Tailored Cognitive Behavioral Intervention

Although cognitive behavioral interventions (CBIs) have demonstrated effectiveness for reducing depressive symptoms in the general population, the mechanism for reducing antepartum depressive symptoms (APDS) in rural low-income and minority women is unknown. This study tested the hypothesis that reducing stress and negative thinking, enhancing self-esteem, and increasing social-support will mediate the effect of a CBI on reducing APDS in rural low-income and minority women. Our findings show that CBI may work through reducing stress and negative thinking and enhancing self-esteem, but not social support. The findings also suggest that mental health care providers should emphasize these activities to reduce antepartum depressive symptoms.

Income inequality and depressive symptoms in South Africa: A longitudinal analysis of the National Income Dynamics Study

Research suggests that income inequality may detrimentally affect mental health. We examined the relationship between district-level income inequality and depressive symptoms among individuals in South Africa-one of the most unequal countries in the world-using longitudinal data from Wave 1 (2008) and Wave 3 (2012) of the National Income Dynamics Study. Depressive symptoms were measured using the Center for Epidemiological Studies of Depression Short Form while district Gini coefficients were estimated from census and survey sources. Age, African population group, being single, being female, and having lower household income were independently associated with higher depressive symptoms. However, in longitudinal, fixed-effects regression models controlling for several factors, district-level Gini coefficients were not significantly associated with depressive symptoms scores. Our results do not support the hypothesis of a causal link between income inequality and depressive symptoms in the short-run. Possible explanations include the high underlying levels of inequality in all districts, or potential lags in the effect of inequality on depression.

Determinants of Obesity and Associated Population Attributability, South Africa: Empirical Evidence from a National Panel Survey, 2008-2012

Background

Obesity is a major risk factor for emerging non-communicable diseases (NCDS) in middle income countries including South Africa (SA). Understanding the multiple and complex determinants of obesity and their true population attributable impact is critical for informing and developing effective prevention efforts using scientific based evidence. This study identified contextualised high impact factors associated with obesity in South Africa.

Methods

Analysis of three national cross sectional (repeated panel) surveys, using a multilevel logistic regression and population attributable fraction estimation allowed for identification of contextualised high impact factors associated with obesity (BMI>30 kg/m²) among adults (15years+).

Results

Obesity prevalence increased significantly from 23.5% in 2008 to 27.2% in 2012, with a significantly (p-value<0.001) higher prevalence among females (37.9% in 2012) compared to males (13.3% in 2012). Living in formal urban areas, white ethnicity, being married, not exercising and/or in higher socio-economic category were significantly associated with male obesity. Females living in formal or informal urban areas, higher crime areas, African/White ethnicity, married, not exercising, in a higher socio-economic category and/or living in households with proportionate higher spending on food (and unhealthy food options) were significantly more likely to be obese. The identified determinants appeared to account for 75% and 43% of male and female obesity respectively. White males had the highest relative gain in obesity from 2008 to 2012.

Conclusions

The rising prevalence of obesity in South Africa is significant and over the past 5 years the rising prevalence of Type-2 diabetes has mirrored this pattern, especially among females. Targeting young adolescent girls should be a priority. Addressing determinants of obesity will involve a multifaceted strategy and requires at individual and population levels. With rising costs in the private and public sector to combat obesity related NCDS, this analysis can inform culturally sensitive mass communications and wellness campaigns. Knowledge of social determinants is critical to develop “best buys”.
