Abstract
BACKGROUND Homelessness is a disruptive life event with profound impacts on children's health. It remains unclear, however, whether homelessness in early life has an enduring association with asthma and wheezing among school-aged children. OBJECTIVE To test whether early-life homelessness is prospectively associated with asthma and wheezing during school-aged years. METHODS We draw on data from 9242 children from the Avon Longitudinal Study of Parents and Children. Children were categorised as 'ever' or 'never' homeless based on maternal reports from the prenatal period through age 5 years. Children were assigned a binary indicator of asthma/wheezing based on maternal reports of asthma and wheezing at ages 6.8, 7.6 and 8.6 years. We used multilevel logistic regression models to test the association of interest in both bivariate analyses and models adjusted for a broad set of potential confounders. We conducted sensitivity analyses using generalised estimating equations and considering asthma and wheezing separately to test the robustness of the results. RESULTS Between 12.1% and 14.3% of children had asthma or wheezing at ages 6.8, 7.6 and 8.6 years, and these conditions were more common among ever homeless participants. Ever-homeless children displayed higher odds of asthma or wheezing than never-homeless children (OR: 1.59, 95% CI 1.02 to 2.48) after adjustment for child, maternal and household risk factors. Sensitivity analyses yielded similar results. CONCLUSION Early-life homelessness is prospectively associated with asthma and wheezing among school-aged children and should be prioritised by interventions promoting healthy child development.

Abstract
Pregnant women face an increased risk of intimate partner violence (IPV). In addition to the risk of violence faced by women, there is a dual concern for risk of harm to the fetus. Expanding knowledge on childbirth outcomes, other domains of children's development have been examined in recent literature. Yet, there is limited comprehensive knowledge in the area. This scoping review study, informed by ecobiodevelopmental theory, mapped evidence associating prenatal IPV exposure and children's development. We searched eight databases, including PubMed, CINAHL, and ERIC. Thirty-one empirical studies published in English that associated prenatal IPV exposure and children's development were eligible for our review. Included studies were published between 2006 and 2022, with 39% published in the most recent 5 years. Eighteen studies had sample sizes smaller than 500, and 21 were atheoretical; six failed to consider covariates. Reviewed studies showed adverse effects of prenatal IPV exposure on psychological, behavioral, physical health, and physiological outcomes, either directly or indirectly via mechanisms such as maternal behavioral health. Due to inconsistency in results and a lack of empirical evidence, however, social and cognitive outcomes were identified as needing further research to enhance our understanding of the global and domain-specific effects of prenatal IPV exposure. Prospective longitudinal studies, driven by theories of causal mechanisms, which adjust for empirically qualified confounders, will be critical to inform practice and policy to promote healthy development of prenatally IPV-exposed children. Incorporating strengths/asset-focused outcomes and examining contextual factors and sex/gender specific effects may advance the knowledge in this area.

Determinants of lung function development from birth to age 5 years: an interrupted time series analysis of a South African birth cohort. THE LANCET. CHILD & ADOLESCENT HEALTH 2024; 8:400-412. [PMID: 38621408 PMCID: PMC11096865 DOI: 10.1016/s2352-4642(24)00072-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 03/03/2024] [Accepted: 03/04/2024] [Indexed: 04/17/2024]
Abstract
BACKGROUND Early life is a key period that determines long-term health. Lung development in childhood predicts lung function attained in adulthood and morbidity and mortality across the life course. We aimed to assess the effect of early-life lower respiratory tract infection (LRTI) and associated risk factors on lung development from birth to school age in a South African birth cohort. METHODS We prospectively followed children enrolled in a population-based cohort from birth (between March 5, 2012 and March 31, 2015) to age 5 years with annual lung function assessment. Data on multiple early-life exposures, including LRTI, were collected. The effect of early-life risk factors on lung function development from birth to age 5 years was assessed using the Generalised Additive Models for Location, Scale and Shape and Interrupted Time Series approach. FINDINGS 966 children (475 [49·2%] female, 491 [50·8%] male) had lung function measured with oscillometry, tidal flow volume loops, and multiple breath washout. LRTI occurred in 484 (50·1%) children, with a median of 2·0 LRTI episodes (IQR 1·0-3·0) per child. LRTI was independently associated with altered lung function, as evidenced by lower compliance (0·959 [95% CI 0·941-0·978]), higher resistance (1·028 [1·016-1·041]), and higher respiratory rate (1·018 [1·063-1·029]) over 5 years. Additional impact on lung function parameters occurred with each subsequent LRTI. Respiratory syncytial virus (RSV) LRTI was associated with lower expiratory flow ratio (0·97 [0·95-0·99]) compared with non-RSV LRTI. Maternal factors including allergy, smoking, and HIV infection were also associated with altered lung development, as was preterm birth, low birthweight, female sex, and coming from a less wealthy household. INTERPRETATION Public health interventions targeting LRTI prevention, with RSV a priority, are vital, particularly in low-income and middle-income settings.

Abstract
BACKGROUND Race-specific spirometry reference equations are used globally to interpret lung function for clinical, research, and occupational purposes, but inclusion of race is under scrutiny. RESEARCH QUESTION Does including self-identified race in spirometry reference equation formation improve the ability of predicted FEV1 values to explain quantitative chest CT abnormalities, dyspnea, or Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification? STUDY DESIGN AND METHODS Using data from healthy adults who have never smoked in both the National Health and Nutrition Survey (2007-2012) and COPDGene study cohorts, race-neutral, race-free, and race-specific prediction equations were generated for FEV1. Using sensitivity/specificity, multivariable logistic regression, and random forest models, these equations were applied in a cross-sectional analysis to populations of individuals who currently smoke and individuals who formerly smoked to determine how they affected GOLD classification and the fit of models predicting quantitative chest CT phenotypes or dyspnea. RESULTS Race-specific equations showed no advantage relative to race-neutral or race-free equations in models of quantitative chest CT phenotypes or dyspnea. Race-neutral reference equations reclassified up to 19% of Black participants into more severe GOLD classes, while race-neutral/race-free equations may improve model fit for dyspnea symptoms relative to race-specific equations. INTERPRETATION Race-specific equations offered no advantage over race-neutral/race-free equations in three distinct explanatory models of dyspnea and chest CT scan abnormalities. Race-neutral/race-free reference equations may improve pulmonary disease diagnoses and treatment in populations highly vulnerable to lung disease.

Early childhood wheezing phenotypes and determinants in a South African birth cohort: longitudinal analysis of the Drakenstein Child Health Study. THE LANCET. CHILD & ADOLESCENT HEALTH 2023; 7:127-135. [PMID: 36435180 PMCID: PMC9870786 DOI: 10.1016/s2352-4642(22)00304-2] [Citation(s) in RCA: 20] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 10/06/2022] [Accepted: 10/10/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Developmental trajectories of childhood wheezing in low-income and middle-income countries (LMICs) have not been well described. We aimed to derive longitudinal wheeze phenotypes from birth to 5 years in a South African birth cohort and compare those with phenotypes derived from a UK cohort. METHODS We used data from the Drakenstein Child Health Study (DCHS), a longitudinal birth cohort study in a peri-urban area outside Cape Town, South Africa. Pregnant women (aged ≥18 years) were enrolled during their second trimester at two public health clinics. We followed up children from birth to 5 years to derive six multidimensional indicators of wheezing (including duration, temporal sequencing, persistence, and recurrence) and applied Partition Around Medoids clustering to derive wheeze phenotypes. We compared phenotypes with a UK cohort (the Avon Longitudinal Study of Parents and Children [ALSPAC]). We investigated associations of phenotypes with early-life exposures, including all-cause lower respiratory tract infection (LRTI) and virus-specific LRTI (respiratory syncytial virus, rhinovirus, adenovirus, influenza, and parainfluenza virus) up to age 5 years. We investigated the association of phenotypes with lung function at 6 weeks and 5 years. FINDINGS Between March 5, 2012, and March 31, 2015, we enrolled 1137 mothers and there were 1143 livebirths. Four wheeze phenotypes were identified among 950 children with complete data: never (480 children [50%]), early transient (215 children [23%]), late onset (104 children [11%]), and recurrent (151 children [16%]). Multivariate adjusted analysis indicated that LRTI and respiratory syncytial virus-LRTI, but not other respiratory viruses, were associated with increased risk of recurrent wheeze (odds ratio [OR] 2·79 [95% CI 2·05-3·81] for all LTRIs; OR 2·59 [1·30-5·15] for respiratory syncytial virus-LRTIs). Maternal smoking (1·88 [1·12-3·02]), higher socioeconomic status (2·46 [1·23-4·91]), intimate partner violence (2·01 [1·23-3·29]), and male sex (2·47 [1·50-4·04]) were also associated with recurrent wheeze. LRTI and respiratory syncytial virus-LRTI were also associated with early transient and late onset clusters. Wheezing illness architecture differed between DCHS and ALSPAC; children included in ALSPAC in the early transient cluster wheezed for a longer period before remission and late-onset wheezing started at an older age, and no persistent phenotype was identified in DCHS. At 5 years, airway resistance was higher in children with early or recurrent wheeze compared with children who had never wheezed. Airway resistance increased from 6 weeks to 5 years among children with recurrent wheeze. INTERPRETATION Effective strategies to reduce maternal smoking and psychosocial stressors and new preventive interventions for respiratory syncytial virus are urgently needed to optimise child health in LMICs.

Abstract
OBJECTIVE To evaluate the relationship between intimate partner violence (IPV) and adult and childhood asthma outcomes. DATA SOURCES We conducted a systematic literature review using 4 databases (PubMed, Ovid MEDLINE, Ovid Embase, and Ovid PsycINFO) with asthma and IPV-associated terms. STUDY SELECTIONS We included published studies, available in English, to October 2021, which included IPV as an exposure and asthma as an outcome. Both adult and pediatric populations were included in the following settings: community, health care, and home. RESULTS There were 37 articles identified. There was evidence among multiple studies to support increased prevalence of asthma in adults exposed to IPV and prevalence and incidence in children with parental IPV exposure. There were fewer studies evaluating IPV exposure and adult asthma morbidity, but they found statistically significant associations between IPV and increased rate of asthma exacerbations and worsened asthma control. There was sparse evidence evaluating a relationship between IPV and adult asthma mortality. There were no studies identified evaluating IPV and childhood asthma morbidity or mortality. CONCLUSION The association between IPV and increased asthma prevalence, incidence, and worsened morbidity merits recognition and further investigation into potential mechanisms. Health care providers can implement practical strategies to help mitigate the negative effects of IPV on health and asthma. These include addressing potential impactful biopsychosocial factors and comorbidities, implementing routine screening and referrals, and partnering with community advocacy organizations. Given their positions of respect and power in society, health care providers can have lasting impacts on the lives of pediatric and adult patients affected by IPV.

Abstract
BACKGROUND Perinatal mental health problems, defined as mental health problems occurring from the start of pregnancy to one year after birth, substantially affect women's and children's quality of life in low- and middle-income countries. In South Africa, despite high prevalence and documented negative impacts, most women do not receive any care. METHODS A modelling study examined the costs of perinatal mental health problems, namely depression and anxiety, for a hypothetical cohort of women and their children in South Africa over part of their life course (10 years for women, 40 years for children). In sensitivity analysis, additional impacts of post-traumatic stress disorder (PTSD) and completed suicide were included. Data sources were published findings from cohort studies, as well as epidemiological and economic data from South Africa. Data from international studies were considered where no data from South Africa were available. RESULTS Lifetime costs of perinatal depression and anxiety in South Africa amount to USD 2.8 billion per annual cohort of births. If the impacts of PTSD and suicide are included, costs increase to USD 2.9 billion. This includes costs linked to losses in quality of life (USD 1.8 billion), losses in income (USD 1.1 billion) and public sector costs (USD 3.5 million). CONCLUSIONS Whilst important progress has been made in South Africa with regards to mental health policies and interventions that include assessment and management of perinatal mental health problems, substantial underinvestment prevents progress. Findings from this study strengthen the economic case for investing in perinatal mental health care.

Abstract
OBJECTIVE The association of perinatal psychological adversity (ie, stressors and distress) with infant lung function (ILF) and development is not well studied in Africa and elsewhere. We determined the association between maternal perinatal psychological adversity and ILF in African infants. DESIGN Prospective longitudinal follow up of the Drakenstein Child Health Study birth cohort. PARTICIPANTS Seven hundred and sixty-two infants aged 6 to 10 weeks and 485 infants who had data for both maternal perinatal psychological adversity and ILF (measured at 6 to 10 weeks and 12 months). METHODS The main analyses were based on cross-sectional measures of ILF at each assessment (6 to 10 weeks or 12 months), using generalized linear models, and then on the panel-data of both longitudinal ILF assessments, using generalised estimating equations, that allowed specification of the within-group correlation structure. RESULTS Prenatal intimate partner violence (IPV) exposure was associated with reduced respiratory resistance at 6 to 10 weeks (beta coefficient [β] = -.131, P = .023); postnatal IPV with reduced ratio of time to peak tidal expiratory flow over total expiratory time (tPTEF /tE ) at 12 months (β = -.206, P = .016); and prenatal depression with lower respiratory rate at 6 to 10 weeks (β = -.044, P = .032) and at 12 months (β = -.053, P = .021). Longitudinal analysis found an association of prenatal IPV with reduced tPTEF /tE (β = -.052, P < .0001); postnatal IPV with decreased functional residual capacity (FRC; β = -.086, P < .0001); prenatal posttraumatic stress disorder with increased FRC (β = .017, P < .0001); prenatal depression with increased FRC (β = .026, P < .0001) and postnatal depression with increased FRC (β = .021, P < .0001). CONCLUSION Screening for psychological adversity and understanding the mechanisms involved may help identify children at risk of altered lung development and inform approaches to treatment.
