Many marine animals have evolved over millions of years to rely on sound as a fundamental component of their habitat. Over the last century, increasing noise from human activities has significantly affected the quality of underwater acoustic habitats. These changes can lead to reduced ability to detect and interpret environmental cues used to perform critical life functions (e.g. select mates, find food, maintain group structure and relationships, avoid predators, navigate). The National Oceanic and Atmospheric Administration (NOAA), as the US federal agency with primary responsibility for protecting marine animals and their habitats, is developing an agency-wide strategy that emphasizes the ocean spaces that these animals need, and the importance of acoustic conditions in those places. This strategy seeks to reach beyond initial goals of reducing acute impacts due to noise (protecting hearing and reducing physical harm) to better account for the importance of underwater sound in marine ecosystems. This paper outlines science needs associated with acoustic habitat characterization and the assessment of noise impacts on habitats, which provide information critical to NOAAís prioritization of future place-based research and management. NOAAís spatial management tools are examined relative to acoustic habitat protection goals, which seek to match the ecological scales over which noise is impacting marine wildlife, including endangered species. Recommended actions are identified to address these broad spatial and long temporal scales, including international work on quieting technologies, registries of accumulated noisy events, and an enhanced role for NOAAís National Marine Sanctuaries in science, management, and outreach associated with acoustic habitat protection.

Objective: Adolescent diet, physical activity and nutritional status are generally known to be sub-optimal. This is an introduction to a special issue of papers devoted to exploring factors affecting diet and physical activity in adolescents, including food insecure and vulnerable groups. Setting: Eight settings including urban, peri-urban and rural across sites from five different low- and middle-income countries. Design: Focus groups with adolescents and caregivers carried out by trained researchers. Results: Our results show that adolescents, even in poor settings, know about healthy diet and lifestyles. They want to have energy, feel happy, look good and live longer, but their desire for autonomy, a need to 'belong' in their peer group, plus vulnerability to marketing exploiting their aspirations, leads them to make unhealthy choices. They describe significant gender, culture and context-specific barriers. For example, urban adolescents had easy access to energy dense, unhealthy foods bought outside the home, whereas junk foods were only beginning to permeate rural sites. Among adolescents in Indian sites, pressure to excel in exams meant that academic studies were squeezing out physical activity time. Conclusions: Interventions to improve adolescents' diets and physical activity levels must therefore address structural and environmental issues and influences in their homes and schools, since it is clear that their food and activity choices are the product of an interacting complex of factors. In the next phase of work, the Transforming Adolescent Lives through Nutrition consortium will employ groups of adolescents, caregivers and local stakeholders in each site to develop interventions to improve adolescent nutritional status.

The author discusses aspects related to medical care of pregnant women and nutrition in low and middle income countries. Topics discussed include evaluation of statistical data by World Health Organization (WHO), aspects related to nutritional balance in food provided to pregnant women, and fetal development.

Evidence is growing for the long-term effects of environmental factors during early-life on later disease susceptibility. It is believed that epigenetic mechanisms (changes in gene function not mediated by DNA sequence alteration), particularly DNA methylation, play a role in these processes. This paper reviews the current state of knowledge of the involvement of C1 metabolism and methyl donors and cofactors in maternal diet-induced DNA methylation changes in utero as an epigenetic mechanism. Methyl groups for DNA methylation are mostly derived from the diet and supplied through C1 metabolism by way of choline, betaine, methionine or folate, with involvement of riboflavin and vitamins B6 and B12 as cofactors. Mouse models have shown that epigenetic features, for example DNA methylation, can be altered by periconceptional nutritional interventions such as folate supplementation, thereby changing offspring phenotype. Evidence of early nutrient-induced epigenetic change in human subjects is scant, but it is known that during pregnancy C1 metabolism has to cope with high fetal demands for folate and choline needed for neural tube closure and normal development. Retrospective studies investigating the effect of famine or season during pregnancy indicate that variation in early environmental exposure in utero leads to differences in DNA methylation of offspring. This may affect gene expression in the offspring. Further research is needed to examine the real impact of maternal nutrient availability on DNA methylation in the developing fetus.

Evidence suggests that risk of chronic diseases may be programmed during the foetal and early life of the infant. With high rates of low birthweight coupled with a rapid nutritional transition, low-income countries are facing an epidemic of chronic diseases. Follow-up of a cohort of adults born during 1964-1978 in an urban slum in Lahore, Pakistan, is presented in this paper. In 695 of these adults (mean age=29.0 years, males=56%), blood pressure, fasting blood glucose, and body mass index (BMI) were measured to assess early-life predictors of risk of chronic diseases. Sixteen percent of the study population was born with a low birthweight (<2,500 g). A significant positive association (p=0.007) was observed between birthweight and BMI; additionally, adjusting for age and gender, the association with BMI was highly significant (p=0.000). Conversely, a significant negative association (p=0.016) was observed between birthweight and adult levels of fasting plasma glucose; after adjustment for age and gender, the association was more significant (p=0.005) No association was observed between birthweight and adult blood pressure. The results suggest that low birthweight may increase later risk of impaired glucose tolerance in urban Pakistani adults. Further research in this area is warranted. [ABSTRACT FROM AUTHOR]

In rural Gambia the risk of mainly infection-related mortality is 10-fold higher for adults born in the nutritionally-debilitating 'hungry' season, suggesting that immune function may be compromised by events early in life. The current programme of research focuses on the biological mechanisms underlying this hypothesis, exploring early-life environmental influences on immune development and the long-term functional consequences these influences may have. Results obtained to date show that thymus development during infancy is critically sensitive to environmental exposures, with smaller thymuses observed in the hungry season. Measurement of the frequency of T-cell receptor excision circles indicate that thymus function is also sensitive to seasonal influences, with further studies implicating variations in breast-milk IL-7 as a possible mediator of these effects. Studies in adults have shown that size at birth is positively correlated with antibody responses to vaccination with polysaccharide antigens, thus providing evidence for long-term functional deficits. The present paper will review progress made to date within this field of research. [ABSTRACT FROM AUTHOR]

This study compared the energy cost of walking in children with cerebral palsy (CP) classified at different levels of the Gross Motor Function Classification System (GMFCS) with that in children with typical development. Sixteen female and 14 male children with CP (mean age 9 years 6 months, SD 2 years 4 months, range 6 years 4 months to 13 years 4 months) and 14 male and 13 female typically developing children (mean age 10 years, SD 1 year 6 months, range 7 years 1 month to 12 years 11 months) participated. Children with CP were classified at GMFCS level I, n=5; level II, n=10; level II, n=9; and level IV, n=6. Energy cost was assessed by the gas dilution method as each child walked around an oval track wearing a dilution mask. Significant differences were found across GMFCS levels (p<0.0001) and between adjacent levels (p<0.013). Children with CP displayed a higher energy cost of walking than the typically developing children (p<0.0001). A strong correlation (0.87) was found between the energy cost of walking and GMFCS level (p<0.01) when children with typical development were assigned a GMFCS level of zero to allow statistical analysis. This indicates increasing energy cost of walking with increasing severity of functional involvement. These differences in energy cost across GMFCS levels provide another distinguishing factor between GMFCS levels and further emphasize the importance of considering metabolic demand in determining treatment options.

Aim: To test the efficacy of T-cell-dependent and T-cell-independent vaccines in rural Gambian children suffering from a range of energy/protein and micronutrient deficiencies.Methods: Nutritional status (anthropometry, haemoglobin, plasma leptin and micronutrient status) and response to two vaccinations (23 valent pneumococcal capsular polysaccharide vaccine, Pneumovax and the Human Diploid-Cell Rabies Vaccine) were assessed in 472 children aged 6 1/2 h to 9 1/2 y.Results: Anthropometry and micronutrient status (as z-scores against European reference values) indicated a range from moderate to severe levels of undernutrition [mean (interquartile range): weight-for-age z-score -1.58 (-2.18 to -0.95); height-for-age z-score -0.94 (-1.51 to -0.35); body-mass-index-for-age z-score -1.43 (-2.05 to -0.84); mid-upper arm circumference -1.41 (-1.72 to -1.13); leptin -1.06 (-1.10 to -1.03); haemoglobin (Hb) -0.30 (-1.18 to 0.79); zinc -1.29 (-2.42 to -0.55); vitamin C -0.01 (-1.18 to 1.15); retinol -1.33 (-1.97 to -0.77)]. A seasonal effect was observed in haemoglobin levels and in all micronutrients (with the exception of zinc and retinol) and in the response to vaccination. After adjusting for seasonality, age and gender, no consistent associations were found between any of the measures of nutritional status and the effectiveness of seroconversion to either of the vaccines.Conclusion: The successful short-term seroconversion to whole inactivated viral and bacterial polysaccharide vaccines indicates that the processes leading to antibody secretion remain intact over a wide range of single and combined nutrient deficiencies.

The use of substances by adolescent African American males is of particular concern because of the damaging effect that drug abuse has not only on the individual and his family but also on the African American community. The literature is scant regarding treatment services and few therapeutic interventions have been specifically designed to holistically meet the needs of these youth. This article proposes the use of Afrocentricity and Reality Therapy as therapeutic bases for substance abuse treatment with this population. [ABSTRACT FROM AUTHOR]

Background: Research over the past decade has suggested that prenatal and early postnatal nutrition influence the risk of developing chronic degenerative diseases up to 60 years later. We now present evidence that risk of death from infectious diseases in young adulthood is similarly programmed by early life events.Methods: In three rural Gambian villages, affected by a marked annual seasonality in diet and disease, we have kept detailed demographic, anthropometric and health records since 1949. Fate was known with certainty for 3,162 individuals (2,059 alive/1,103 dead, most dying in childhood). For this case-control analysis of antecedent predictors of premature mortality, all adult deaths (n = 61) were paired with two randomly selected controls matched for sex and year of birth.Results: Mean age at death was 25 (SD: 8) years. Adult death was associated with a profound bias in month of birth with 49 cases born in the nutritionally-debilitating hungry season (Jul-Dec) versus 12 in the harvest season (Jan-Jun). Relative to harvest season the hazard ratio for early death in hungry-season births rose from 3.7 (for deaths >14.5 years, P = 0.000013) to 10.3 (for deaths >25 years, P = 0.00002). Anthropometric and haematological status at 18 months of age was identical in cases and controls, indicating an earlier origin to the defect. Most deaths for which cause was known had a definite or possible infectious aetiology; none were from degenerative diseases of affluence.Conclusions: Early life exposures, correlated with season of birth, strongly influence susceptibility to fatal infections in young adulthood. The evidence suggests that nutritionally-mediated intrauterine growth retardation may permanently impair the development of immune function. [ABSTRACT FROM AUTHOR]

Objectives: We attempted to determine if mothers of overweight daughters accurately perceived the daughters' weight category and whether physician diagnosis of overweight was associated with accurate maternal perception of a daughter's weight.Design: This was a cross-sectional study that used the Morehouse School of Medicine Obesity Health Belief Survey. Descriptive statistics were used with categorical variables; chi2 was used to identify associations between dichotomous and categorical data.Setting: Participants were enrolled in the study at the West End Medical Centers Inc., a federally qualified health center in Atlanta, Georgia.Results: Among overweight girls, 19% of mothers underestimated the girls' weight category, and 60% of the mothers underestimated the magnitude of their daughters' weight category (P < .001). Among the mothers of girls at risk for overweight, there was a statistically significant association between being told their daughter was overweight by a physician and an accurate perception of the daughter's weight category by the motherConclusion: Despite this national epidemic, not all of mothers of overweight girls identify them as overweight. Physicians may play an important role in helping mothers recognize overweight in their daughter. Ultimately, accurately perceiving their daughters' weight category may influence maternal readiness to change to reduce overweight and reduce the health burden of overweight. [ABSTRACT FROM AUTHOR]

After the near-complete cessation of commercial whaling, ship collisions have emerged as a primary threat to large whales, but knowledge of collision risk is lacking across most of the world's oceans. We compiled a dataset of 435,000 whale locations to generate global distribution models for four globally ranging species. We then combined >35 billion positions from 176,000 ships to produce a global estimate of whale-ship collision risk. Shipping occurs across 92% of whale ranges, and <7% of risk hotspots contain management strategies to reduce collisions. Full coverage of hotspots could be achieved by expanding management over only 2.6% of the ocean's surface. These inferences support the continued recovery of large whales against the backdrop of a rapidly growing shipping industry.

Health care transitions, movements between providers or settings, can lead to poor outcomes, higher resource utilization, and even higher costs. Health care transitions can be complex experiences for sexual and gender diverse (SGD) individuals, especially when there is a need for ongoing health care (e.g. gender-affirming therapy, depression). Engaging new providers can lead to setbacks in trust requiring self-disclosure SGD-identities all over again. The Transitional Care Model (TCM) supports improvement of outcomes associated with health care transitions; however, it has not been tailored to address the unique needs of SGD populations. A sample of adult SGD patients ( n  = 17) and SGD health experts ( n  = 11) from across the US completed a six cycle, electronic, modified Delphi process to adapt the TCM for the SGD population. The iterative process produced a TCM for SGD populations including eight refined and renamed components with SGD-specific descriptions and exemplars. The resulting model, the Sexual and Gender Diverse Healthcare Navigation Model, provides an eight-component adaptive model of transitional care that centers SGD patients and their support systems across complex health care systems. The consensus panel provided descriptions for each of the eight resulting components-identifying three foundational components-the right staffing, awareness of needs and risks, and engaging individuals and their support systems throughout transitions in care. This model stands to support improved health outcomes among SGD through a multi-component, patient centered approach to health care navigation.

Background: The number of women entering pregnancy with overweight or obesity is increasing. This can increase the risk for excessive gestational weight gain (GWG) which is associated with health complications for mother and baby. There are limited evidence-based interventions within antenatal care settings to encourage healthy eating and physical activity behaviours and support women with managing GWG., Methods: A previous habit-based intervention 'Ten Top Tips for a Healthy Weight' (10TT) was adapted and made suitable for pregnancy in line with the Medical Research Council's (MRC) complex intervention development guidelines. It involved three key activities: (1) identifying the evidence base; (2) identifying appropriate theory; and, (3) modelling processes. A core element was integrating lived experience via personal and public involvement (PPI)., Results: The original 10TTs were adapted with PPI in line with current advice on nutrition and physical activity in pregnancy. New intervention materials were devised, including a leaflet and a logbook and app for self-monitoring to be delivered alongside a brief 1:1 conversation. Behaviour change techniques (BCTs) included in the new materials were coded using a number of behavioural taxonomies. An E-learning resource was created to help standardise the approach to delivery of the intervention and avoid stigmatising conversations., Conclusion: Following MRC guidance for the development of complex interventions alongside significant PPI allowed for the adaption of 10TT habit-based weight management intervention into the 'Healthy Habits in Pregnancy and Beyond' (HHIPBe) intervention. The feasibility and acceptability of implementing this intervention in the antenatal setting will be explored in a feasibility randomised controlled trial., Trial Registration: This study was registered on Clinical Trials as 'Healthy Habits in Pregnancy and Beyond (HHIPBe)' ClinicalTrials.gov Identifier: NCT04336878. The study was registered on 07/04/2020., Competing Interests: Declarations Ethics approval and consent to participate Ethical approval and informed consent were not required for the intervention development phase of the study as it involved PPI contributors; it did not include human research participants.

Objective: To compare rates of Clostridioides difficile infection (CDI) recurrence following initial occurrence treated with tapered enteral vancomycin compared to standard vancomycin., Design: Retrospective cohort study., Setting: Community health system., Patients: Adults ≥18 years of age hospitalized with positive C. difficile polymerase chain reaction or toxin enzyme immunoassay who were prescribed either standard 10-14 days of enteral vancomycin four times daily or a 12-week tapered vancomycin regimen., Methods: Retrospective propensity score pair matched cohort study. Groups were matched based on age < or ≥ 65 years and receipt of non- C. difficile antibiotics during hospitalization or within 6 months post-discharge. Recurrence rates were analyzed via logistic regression conditioned on matched pairs and reported as conditional odds ratios. The primary outcome was recurrence rates compared between standard vancomycin versus tapered vancomycin for treatment of initial CDI., Results: The CDI recurrence rate at 6 months was 5.3% (4/75) in the taper cohort versus 28% (21/75) in the standard vancomycin cohort. The median time to CDI recurrence was 115 days versus 20 days in the taper and standard vancomycin cohorts, respectively. When adjusted for matching, patients in the taper arm were less likely to experience CDI recurrence at 6 months when compared to standard vancomycin (cOR = 0.19, 95% CI 0.07-0.56, p < 0.002)., Conclusions: Larger prospective trials are needed to elucidate the clinical utility of tapered oral vancomycin as a treatment option to achieve sustained clinical cure in first occurrences of CDI.

Background: Sexual and gender diverse (SGD) people in the United States (US) experience health inequities due to societal stigma and marginalisation. The nursing workforce must provide evidence-based affirming, inclusive and culturally responsive care for SGD people to meet individual and community health needs and eliminate disparities., Aims: The purpose of this scoping review was to synthesise what is known about (1) nurses' knowledge, skills and attitudes related to caring for SGD people in the US and (2) the existence, development and evaluation of SGD-related educational offerings available to practicing nurses in the US to develop the knowledge and skills needed to promote the health and wellbeing of SGD individuals, families and communities., Methods: This review followed the scoping review methodology and PRISMA for Scoping Reviews (PRISMA-ScR)., Data Sources: In conjunction with a health librarian, an electronic literature search was conducted using PubMed, LGBT Health, CINAHL, ERIC and Health Source-Nursing., Results: Thirty-two studies were included in this review, including quantitative and qualitative studies that sought to understand the knowledge, attitudes and clinical experiences of nurses related to the care of SGD people; studies that tested educational interventions and studies that identified educational barriers and facilitators. Major gaps in education, practice and research, as well as methodological limitations of existing studies, were noted., Conclusion: Nurses would benefit from expanded access to effective standardised foundational SGD-related health continuing education to help prepare them to care for diverse patient populations. Equity, inclusivity and dignity are key values of the nursing profession. It is imperative that nurses have the knowledge and skills to apply these values consistently in day-to-day professional practice across populations and settings., Impact: There is an urgent need to develop standardised, easily accessible evidence-based educational content to address nurses' knowledge of and attitudes towards caring for SGD people., Reporting Method: This study adhered to the PRISMA-ScR reporting guidelines., Patient or Public Contribution: There was no patient or public contribution to this study., (© 2024 John Wiley & Sons Ltd.)

Background: The intersecting crises of climate change, food insecurity, and undernutrition disproportionately affect children. Understanding the effect of heat on growth from conception to 2 years of age is important because of mortality and morbidity implications in the near term and over the life course., Methods: In this secondary analysis, we used longitudinal pregnancy cohort data from the Early Nutrition and Immunity Development (ENID) randomised controlled trial in West Kiang, The Gambia, which occurred between Jan 20, 2010, and Feb 10, 2015. The ENID trial assessed micronutrient supplementation in the first 1000 days of life starting from 20 weeks' gestation, during which anthropometric measurements were collected prospectively. We used multivariable linear regression to assess the effect of heat stress (defined by Universal Thermal Climate Index [UTCI]) on intrauterine growth restriction based on length-for-gestational age Z score (LGAZ), weight-for-gestational age Z score (WGAZ), and head circumference-for-gestational age Z score (HCGAZ) at birth, and assessed for effect modification of supplement intervention on the relationship between heat stress and infant anthropometry. We used multivariable, multilevel linear regression to evaluate the effect of heat stress on infant growth postnatally based on weight-for-height Z score (WHZ), weight-for-age Z score (WAZ), and height-for-age Z score (HAZ) from 0 to 2 years of age., Findings: Complete data were available for 668 livebirth outcomes (329 [49%] female infants and 339 [51%] male infants). With each 1°C increase in mean daily maximum UTCI exposure, in the first trimester, we observed a reduction in WGAZ (-0·04 [95% CI -0·09 to 0·00]), whereas in the third trimester, we observed an increase in HCGAZ (0·06 [95% CI 0·00 to 0·12]), although 95% CIs included 0. Maternal protein-energy supplementation in the third trimester was associated with reduced WGAZ (-0·16 [-0·30 to -0·02]) with each 1°C increase in mean daily maximum UTCI exposure, while no effect of heat stress on WGAZ was found with either standard care (iron and folate) or multiple micronutrient supplementation. For the postnatal analysis, complete anthropometric data at 2 years were available for 645 infants (316 [49%] female infants and 329 [51%] male infants). Postnatally, heat stress effect varied by infant age, with infants aged 6-18 months being the most affected. In infants aged 12 months exposed to a mean daily UTCI of 30°C (preceding 90-day period) versus 25°C UTCI, we observed reductions in mean WHZ (-0·43 [95% CI -0·57 to -0·29]) and mean WAZ (-0·35 [95% CI -0·45 to -0·26]). We observed a marginal increase in HAZ with increasing heat stress exposure at age 6 months, but no effect at older ages., Interpretation: Our results suggest that heat stress impacts prenatal and postnatal growth up to 2 years of age but sensitivity might vary by age. In the context of a rapidly warming planet, these findings could have short-term and long-term health effects for the individual, and immediate and future implications for public child health., Funding: Wellcome Trust., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2024 The Author(s).

Background: Undernutrition during pregnancy increases the risk of giving birth to a small vulnerable newborn. Small-quantity lipid-based nutrient supplements (SQ-LNSs) contain both macro- and micronutrients and can help prevent multiple nutritional deficiencies., Objectives: We examined the effects of SQ-LNSs provided during pregnancy compared with 1) iron and folic acid or standard of care (IFA/SOC) or 2) multiple micronutrient supplements (MMSs) and identified characteristics that modified the estimates of effects of SQ-LNSs on birth outcomes., Methods: We conducted a 2-stage meta-analysis of individual participant data from 4 randomized controlled trials of SQ-LNSs provided during pregnancy (n = 5273). We generated study-specific and subgroup estimates of SQ-LNS compared with IFA/SOC or MMS and pooled the estimates. In sensitivity analyses, we examined whether the results differed depending on methods for gestational age dating, birth anthropometry, or study design., Results: SQ-LNSs (compared with IFA/SOC) increased birth weight [mean difference: +49 g; 95% confidence interval (CI): 26, 71 g] and all birth anthropometric z-scores (+0.10-0.13 standard deviation); they reduced risk of low birth weight by 11%, newborn stunting by 17%, newborn wasting by 11%, and small head size by 15%. Only 2 trials compared SQ-LNSs and MMSs; P values for birth outcomes were >0.10 except for head circumference (e.g., z-score for gestational age: +0.11; 95% CI: -0.01, 0.23). Effect estimates for SQ-LNSs compared with IFA/SOC were greater among female infants and, for certain outcomes, among mothers with body mass index <20 kg/m 2 , inflammation, malaria, or household food insecurity. Effect estimates for SQ-LNSs compared with MMSs were greater for certain outcomes among female infants, first-born infants, and mothers <25 y., Conclusions: SQ-LNSs had positive impacts on multiple outcomes compared to IFA/SOC, but further research directly comparing SQ-LNSs and MMSs is needed. Targeting SQ-LNSs to vulnerable subgroups may be worth considering., Clinical Trial Registry: This study was registered at PROSPERO as CRD42021283391., Competing Interests: Conflict of interest N.F.K. is on the Editorial Board of the American Journal of Clinical Nutrition and played no role in the Journal’s evaluation of the manuscript., (Copyright © 2024 The Author(s).

There is a scarcity of prospective longitudinal research targeted at early postnatal life which maps developmental pathways of early-stage processing and brain specialisation in the context of early adversity. Follow up from infancy into the one-five year age range is key, as it constitutes a critical gap between infant and early childhood studies. Availability of portable neuroimaging (functional near infrared spectroscopy (fNIRS) and electroencephalography (EEG)) has enabled access to rural settings increasing the diversity of our sampling and broadening developmental research to include previously underrepresented ethnic-racial and geographical groups in low- and middle- income countries (LMICs). The primary objective of the Brain Imaging for Global Health (BRIGHT) project was to establish brain function - using longitudinal data from mother - for-age reference curves infant dyads living in the UK and rural Gambia and investigate the association between context-associated moderators and developmental trajectories across the first two years of life in The Gambia. In total, 265 participating families were seen during pregnancy, at 7-14 days, 1-, 5-, 8-, 12-, 18- and 24-months post-partum. An additional visit is now underway at 3-5 years to assess pre-school outcomes. The majority of our Gambian cohort live in poverty, but while resource-poor in many factors they commonly experience a rich and beneficial family and caregiving context with multigenerational care and a close-knit supportive community. Understanding the impact of different factors at play in such an environment ( i.e. , detrimental undernutrition versus beneficial multigenerational family support) will (i) improve the representativeness of models of general cognitive developmental pathways from birth, (ii) identify causal pathways of altered trajectories associated with early adversity at both individual and group level, and (iii) identify the context-associated moderators ( i.e. social context) that protect development despite the presence of poverty-associated challenges. This will in turn contribute to the development of targeted interventions., Competing Interests: No competing interests were disclosed., (Copyright: © 2024 Lloyd-Fox S et al.)
