Supporting Cook Island communities to access DOHaD evidence.

Developmental origins of health and disease research have cemented relationships between the early-life environment and later risk of non-communicable diseases (NCDs). However, there is limited translation of this knowledge in developing-economy nations, such as the Cook Islands, that carry exceptionally high NCD burdens. Considering the evidence, Cook Islands leaders identified a need for increased community awareness of the importance of early-life nutrition. Using a community-based participatory research approach, this study aimed to engage Cook Islands community representatives in the co-construction of a contextually relevant early-life nutrition resource. A booklet distributed to mothers in Australia and New Zealand was used as a starting point. Ten semi-structured focus groups (n = 60) explored views regarding the existing resource and options for contextual adaptation. Three core themes were identified: knowledge of the importance of early-life nutrition, recognition of the need for an early-life nutrition resource and the importance of resources being context specific. A draft booklet was created based on these discussions. Participants were invited to give feedback via a second round of focus groups. This confirmed that the voice of the community was represented in the draft booklet. Suggestions for additional material not included in the original resource were also identified. We report on the process and outcomes of the co-construction with community representatives of a resource that has the potential to be used to stimulate community-level discussion about the importance of early-life nutrition. It is crucial that communities have an active voice in research and in making decisions about interventions for their population.

DOHaD in low- and middle-income countries: a systematic review exploring gaps in DOHaD population studies.

Low- and middle-income countries (LMICs) are disproportionately affected by non-communicable diseases (NCDs), accounting for more than 80% of NCD-related deaths globally. Research into early-life influences on these diseases via the developmental origins of health and disease (DOHaD) paradigm has informed health promotion interventions and policies focused on optimising early-life health. However, little is known about where this research occurs and whether it reaches and reflects the countries most affected by NCDs. This review searched for DOHaD studies that investigated relationships between factors during pregnancy and at birth, with later-life NCD incidence, risk and related mortality. The aim of this review was to identify where DOHaD research has been conducted and whether this focus is appropriate and relevant, given the differential burden of NCDs. Embase, MEDLINE and Scopus were searched, and eligibility screening processes identified 136 final articles. This review found that 49.7% of DOHaD research was conducted on populations within Western Europe, 15.9% in East Asia, 12.7% in North America, 8.3% in Latin America and the Caribbean, and fewer in Australasia, South Asia, the Middle East, the Africas, and Central Asia. When categorised by income, this review found that 76.4% of studies were based in high-income countries, 19.1% in upper-middle-income and 4.5% in lower-middle-income countries. No studies were based in low-income countries. There is therefore a marked disconnect between where DOHaD research is undertaken and where the greatest NCD disease burden exists. Increasing DOHaD research capacity in LMICs is crucial to informing local strategies that can contribute to reducing the incidence of NCDs.

Socioeconomic characteristics of women with substance use disorder during pregnancy and neonatal outcomes in their newborns: A national registry study from the Czech Republic.

BACKGROUND: Maternal substance use can pose a risk to the fetal health. We studied the background characteristics of women with substance use disorders (SUDs) and selected neonatal outcomes in their children. MATERIAL AND METHODS: A database-linkage study was performed. The sample consisted of pregnant women with a SUD during pregnancy (ICD-10 diagnosis F10-F19 except F17, n = 1710), women not diagnosed with a SUD (n = 1,511,310) in Czechia in 2000-2014, and their children. The monitored neonatal outcomes were gestational age, birth weight, preterm birth, and small-for-gestational age (SGA). Binary logistic regression adjusted for age, marital status, education, concurrent substance use, and prenatal care was performed. RESULTS: Women with illicit SUDs were younger, more often unmarried, with a lower level of education, a higher abortion rate, a higher smoking rate, and lower compliance to prenatal care than women with a SUD related to alcohol, or sedatives and hypnotics (SH). Women with a SUD had worse socioeconomic situations, poorer pregnancy care, and worse neonatal outcomes than women without a SUD. After adjustment, we found no difference in SGA between the illicit SUD groups and the alcohol and the SH groups. The newborns from all SUD groups had a higher risk of SGA when compared to women without a SUD. However after adjustment, the difference remained significant just in the alcohol group (OR = 1.9, 95 % CI = 1.4-2.6). CONCLUSION: Mother's SUD during pregnancy increased risk of fetal growth restriction as measured by SGA. The role of maternal socioeconomic and lifestyle factors for the risk of SGA was substantial.

The economic burden of the opioid epidemic on states: the case of Medicaid.

The societal burden of opioid use disorder (OUD) is considerable and contributes to increased healthcare costs and overdose deaths. However, the burden is not well understood. The purpose of this analysis is to estimate the state Medicaid programs' costs for treating OUD and how these costs have changed over time. We used data from the Medicaid Analytic eXtract files from 17 states between 1999 and 2013 to examine the healthcare costs associated with OUD. Inpatient, outpatient, and prescription medication costs related to the treatment of OUD were included, as were excess costs for other healthcare services (eg, general medical care) for individuals with OUD relative to a comparison group of individuals without OUD matched on age, sex, and state. We then extrapolated our results to the entire US Medicaid population using population-based sample weights. All costs were adjusted for inflation and are reported in 2017 US dollars. During our study period, the number of patients who were diagnosed with OUD increased 378%, from 39,109 (0.21% of total Medicaid enrollment) in 1999 to 186,979 (0.60% of total Medicaid enrollment) in 2013 in our 17-state sample. Even after adjusting for inflation, total Medicaid costs associated with OUD more than tripled during this time, reaching more than $3 billion in 2013, from $919 million in 1999. Most of this growth was due to excess non-OUD treatment costs for patients with OUD, which increased 363% over the period; the rate of growth is triple the expenditures for OUD treatment services. When the results were extrapolated to the entire United States, the Medicaid costs associated with OUD increased from more than $2 billion in 1999 to more than $8 billion in 2013. The total cumulative costs that were associated with OUD for this extrapolated 50-state sample over a 15-year time period amounts to more than $72.4 billion. OUD imposes considerable financial burden on state Medicaid programs, and the burden is increasing over time.

Admissions for hypoglycaemia after 35 weeks of gestation: perinatal predictors of cost of stay.

BACKGROUND: Hypoglycaemia accounts for approximately one-tenth of term admissions to neonatal units can cause long-term neurodevelopmental impairment and is associated with the significant burden to the affected infants, families and the health system. OBJECTIVE: To define the prevalence, length and cost of admissions for hypoglycaemia in infants born at greater than 35 weeks gestation and to identify antenatal and perinatal predictors of those outcomes. MATERIALS AND METHODS: This was a retrospective audit of infants admitted for hypoglycaemia between 1 January 2012 and 31 December 2015, in a level three neonatal intensive care unit at King's College Hospital NHS Foundation Trust, London. The main outcome measures were the prevalence, length and cost of admissions for hypoglycaemia and antenatal and postnatal predictors of the length and cost of the stay. RESULTS: There were 474 admissions for hypoglycaemia (17.8% of total admissions). Their median (IQR) blood glucose on admission was 2.1 (1.7-2.4) mmol/l, gestation at delivery 38.1 (36.7-39.3) weeks, birthweight percentile 31.4 (5.4-68.9), their length of stay was 3.0 (2.0-5.0). Admissions equated to a total of 2107 hospital days. The total cost of the stay was 1,316,591 Great Britain pound. The antenatal factors associated with admission for hypoglycaemia were maternal hypertension (19.8%), maternal diabetes (24.5%), foetal growth restriction (FGR) (25.9%) and pathological intrapartum cardiotocograph (23.4%). In 13.7% of cases, there was no associated pregnancy complication. Multivariate logistic regression analysis demonstrated lower gestational age, z-score birthweight squared, exclusive breastfeeding and maternal prescribed nifedipine were independently associated with the length and cost of the stay. CONCLUSION: Hypoglycaemia accounted for approximately one-fifth of admissions after 35-week gestation. Lower gestational age and admission blood glucose, low and high z-score birthweight, maternal nifedipine and exclusive breastfeeding are associated with longer duration of stay.

Early life risk exposure and stunting in urban South African 2-year old children.

Stunting is a measure of overall nutritional status and is a major public health concern because of its association with child mortality and morbidity and later adult performance. This study examined the effects of pregnancy events, birth characteristics and infant risk exposure on stunting at age 2 years. The study, established in 1990 in Soweto, an urban South African township, included 1098 mother-infant pairs enroled in the Birth to Twenty Plus longitudinal birth cohort study. In total, 22% of children were stunted at age 2 years, with males at greater risk than females [24.8 v. 19.4%, odds ratio (OR)=1.38; 95% confidence interval (CI): 1.03, 1.83]. In unadjusted analysis, male sex, household socio-economic status (SES), overcrowding, maternal age, maternal education, single motherhood, ethnicity, birth weight, gestational age and duration of infant breastfeeding were all significantly associated with stunting. In multivariable analysis, higher birth weight was protective against stunting for both sexes. Higher maternal education was protective for females only (adjusted odds ratio (AOR)=0.35; 95% CI: 0.14, 0.87), whereas wealthier household SES protected males (AOR for richest SES group=0.39; 95% CI: 0.16, 0.92). In this and other similar settings, current stunting prevention efforts focussing on primarily providing targeted proximal interventions, such as food supplements, risk undermining the critical importance of addressing key distal determinants of stunting such as SES and maternal education.

Particulate Matter Exposure and Preterm Birth: Estimates of U.S. Attributable Burden and Economic Costs.

BACKGROUND: Preterm birth (PTB) rates (11.4% in 2013) in the United States remain high and are a substantial cause of morbidity. Studies of prenatal exposure have associated particulate matter ≤ 2.5 µm in diameter (PM2.5) and other ambient air pollutants with adverse birth outcomes; yet, to our knowledge, burden and costs of PM2.5-attributable PTB have not been estimated in the United States. OBJECTIVES: We aimed to estimate burden of PTB in the United States and economic costs attributable to PM2.5 exposure in 2010. METHODS: Annual deciles of PM2.5 were obtained from the U.S. Environmental Protection Agency. We converted PTB odds ratio (OR), identified in a previous meta-analysis (1.15 per 10 µg/m3 for our base case, 1.07-1.16 for low- and high-end scenarios) to relative risk (RRs), to obtain an estimate that better represents the true relative risk. A reference level (RL) of 8.8 µg/m3 was applied. We then used the RR estimates and county-level PTB prevalence to quantify PM2.5-attributable PTB. Direct medical costs were obtained from the 2007 Institute of Medicine report, and lost economic productivity (LEP) was estimated using a meta-analysis of PTB-associated IQ loss, and well-established relationships of IQ loss with LEP. All costs were calculated using 2010 dollars. RESULTS: An estimated 3.32% of PTBs nationally (corresponding to 15,808 PTBs) in 2010 could be attributed to PM2.5 (PM2.5 > 8.8 µg/m3). Attributable PTBs cost were estimated at $5.09 billion [sensitivity analysis (SA): $2.43-9.66 B], of which $760 million were spent for medical care (SA: $362 M-1.44 B). The estimated PM2.5 attributable fraction (AF) of PTB was highest in urban counties, with highest AFs in the Ohio Valley and the southern United States. CONCLUSIONS: PM2.5 may contribute substantially to burden and costs of PTB in the United States, and considerable health and economic benefits could be achieved through environmental regulatory interventions that reduce PM2.5 exposure in pregnancy.

Gestational weight gain and the risk of offspring obesity at 10 and 16 years: a prospective cohort study in low-income women.

OBJECTIVE: To study the association between gestational weight gain (GWG) and offspring obesity risk at ages chosen to approximate prepuberty (10 years) and postpuberty (16 years). DESIGN: Prospective pregnancy cohort. SETTING: Pittsburgh, PA, USA. SAMPLE: Low-income pregnant women (n = 514) receiving prenatal care at an obstetric residency clinic and their singleton offspring. METHODS: Gestational weight gain was classified based on maternal GWG-for-gestational-age Z-score charts and was modelled using flexible spline terms in modified multivariable Poisson regression models. MAIN OUTCOME MEASURES: Obesity at 10 or 16 years, defined as body mass index (BMI) Z-scores ≥95th centile of the 2000 CDC references, based on measured height and weight. RESULTS: The prevalence of offspring obesity was 20% at 10 years and 22% at 16 years. In the overall sample, the risk of offspring obesity at 10 and 16 years increased when GWG exceeded a GWG Z-score of 0 SD (equivalent to 30 kg at 40 weeks); but for gains below a Z-score of 0 SD there was no relationship with child obesity risk. The association between GWG and offspring obesity varied by prepregnancy BMI. Among mothers with a pregravid BMI <25 kg/m(2) , the risk of offspring obesity increased when GWG Z-score exceeded 0 SD, yet among overweight women (BMI ≥25 kg/m(2) ), there was no association between GWG Z-scores and offspring obesity risk. CONCLUSIONS: Among lean women, higher GWG may have lasting effects on offspring obesity risk.

Reducing Periconceptional Methylmercury Exposure: Cost-Utility Analysis for a Proposed Screening Program for Women Planning a Pregnancy in Ontario, Canada.

BACKGROUND: The assessment of neurodevelopmental effects in children associated with prenatal methylmercury exposure, from contaminated fish and seafood in the maternal diet, has recently been strengthened by adjustment for the negative confounding resulting from co-exposure to beneficial polyunsaturated fatty acids (PUFAs). OBJECTIVES: We aimed to determine the cost-effectiveness of a periconceptional screening program of blood mercury concentration for women planning to become pregnant in Ontario, Canada. Fish intake recommendations would be provided for those found to have blood mercury levels above the intervention threshold. METHODS: Analysis was conducted using a combined decision tree/Markov model to compare the proposed screening intervention with standard care from a societal perspective over a lifetime horizon. We used the national blood mercury distributions of women 20-49 years of age reported in the Canadian Health Measures Survey from 2009 through 2011 to determine the cognitive deficits associated with prenatal methylmercury exposure for successful planned pregnancies. Outcomes modeled included the loss in quality of life and the remedial education costs. Value of information analysis was conducted to assess the underlying uncertainty around the model results and to identify which parameters contribute most to this uncertainty. RESULTS: The incremental cost per quality-adjusted life year (QALY) gained for the proposed screening intervention was estimated to be Can$18,051, and the expected value for a willingness to pay of Can$50,000/QALY to be Can$0.61. CONCLUSIONS: Our findings suggest that the proposed periconceptional blood mercury screening program for women planning a pregnancy would be highly cost-effective from a societal perspective. The results of a value of information analysis confirm the robustness of the study's conclusions.

Early-life course socioeconomic factors and chronic kidney disease.

Kidney failure or ESRD affects approximately 650,000 Americans, whereas the number with earlier stages of CKD is much higher. Although CKD and ESRD are usually associated with adulthood, it is likely that the initial stages of CKD begin early in life. Many of these pathways are associated with low birth weight and disadvantaged socioeconomic status (SES) in childhood, translating childhood risk into later-life CKD and kidney failure. Social factors are thought to be fundamental causes of disease. Although the relationship between adult SES and CKD has been well established, the role of early childhood SES for CKD risk remains obscure. This review provides a rationale for examining the association between early-life SES and CKD. By collecting data on early-life SES and CKD, the interaction with other periods in the life course could also be studied, allowing for examination of whether SES trajectories (eg, poverty followed by affluence) or cumulative burden (eg, poverty at multiple time points) are more relevant to lifetime CKD risk.

Early start: a cost-beneficial perinatal substance abuse program.

OBJECTIVE: To conduct a cost-benefit analysis of Early Start, an integrated prenatal intervention program for stopping substance use in pregnancy. METHODS: A retrospective cohort study was conducted of 49,261 women who had completed prenatal substance abuse screening questionnaires at obstetric clinics and who had undergone urine toxicology screening tests. Four study groups were compared: women screened and assessed positive and followed by Early Start (screened-assessed-followed, n=2,032), women screened and assessed positive without follow-up (screened-assessed, n=1,181), women screened positive only (screened-positive-only, n=149), women in the control group who screened negative (control, n=45,899). Costs associated with maternal health care (prenatal through 1 year postpartum), neonatal birth hospitalization care, and pediatric health care (through 1 year) were adjusted to 2009 dollars. Mean costs were calculated and adjusted for age, race, education, income, marital status, and amount of prenatal care. RESULTS: Screened-positive-only group adjusted mean maternal total costs ($10,869) were significantly higher than screened-assessed-followed, screened-assessed, and control groups ($9,430; $9,230; $8,282; all P<.001). Screened-positive-only group adjusted mean infant total costs ($16,943) were significantly higher than screened-assessed-followed, screened-assessed, and control groups ($11,214; $11,304; $10,416; all P<.001). Screened-positive-only group adjusted mean overall total costs ($27,812) were significantly higher than screened-assessed-followed, screened-assessed, and control groups ($20,644; $20,534; $18,698; all P<.001). Early Start implementation costs were $670,600 annually. Cost-benefit analysis showed that the net cost benefit averaged $5,946,741 per year. CONCLUSION: Early Start is a cost-beneficial intervention for substance use in pregnancy that improves maternal-infant outcomes and leads to lower overall costs by an amount significantly greater than the costs of the program.

Development of a model to assess the cost-effectiveness of gestational diabetes mellitus screening and lifestyle change for the prevention of type 2 diabetes mellitus.

Gestational diabetes mellitus (GDM) is increasingly recognized as an opportunity for early prevention of diabetes and other diseases over the lifespan, and may be responsible for up to 30% of cases of type 2 diabetes. A newly developed mathematical model (the GDModel) provides provisional estimates of the cost and health impact of various GDM screening and management choices, and calculates averted disability-adjusted life-years (DALYs). The model was piloted in 5 different healthcare facilities in India and Israel. Universal screening of pregnant women followed by postpartum lifestyle management yielded net savings of US$78 per woman with GDM in India and US$1945 per woman in Israel. The estimated DALYs averted were 2.33 in India and 3.10 in Israel. With lower GDM prevalence, intervention efficacy, and type 2 diabetes incidence, the intervention had a net cost in India, with a cost per DALY averted of US$11.32. This was far below the WHO definition of "very cost-effective," set at annual GDP per capita. The intervention in Israel remained cost-saving. GDM screening and postpartum lifestyle management are either cost-saving or have a net cost but an attractive cost-effectiveness ratio. Some input values are currently being refined. Nevertheless, the current findings of cost-savings or favorable cost-effectiveness are robust to a wide range of plausible input values, including highly unfavorable values. The GDModel will be further developed into a user-friendly tool that can guide policy-makers on decisions regarding GDM screening strategies and guidelines.

The contribution of prenatal and postnatal maternal anxiety and depression to child maladjustment.

BACKGROUND: The adverse effect of both pre- and post-natal maternal anxiety and depression on the development of offspring is shown by a large body of research. No published studies, however, have simultaneously: (i) controlled for co-occurring prenatal risks that may influence maternal prenatal anxiety and depression; (ii) compared the relative contributions of prenatal and postnatal maternal anxiety and depression on child functioning; and (iii) assessed a full range of child psychopathology and functioning to determine the relative effects of prenatal and postnatal anxiety and depression in the mother. METHOD: Using 3,298 mother-offspring pairs, the authors examined these factors in a single-path analytic model. Measurements of maternal anxiety and depression were collected at two time points: 32 weeks prenatal and 1.5 years postnatal. Other prenatal risks were assessed between 8 and 32 weeks of gestation. Child outcomes included (a) ordered-categorical measures of DSM-IV externalizing and internalizing disorders, and (b) an assessment of verbal IQ. RESULTS: In both the prenatal and postnatal periods, maternal depression had a wider impact on different types of child maladjustment than maternal anxiety, which appeared more specific to internalizing difficulties in the child. Of note, prenatal risks were prospectively associated with child externalizing difficulties and verbal IQ, beyond the effects of prenatal and postnatal maternal anxiety and depression. CONCLUSION: The present results suggest that addressing both maternal anxiety and depression, in the prenatal and postnatal periods-as well as associated risk factors-may be the most effective approach to prevent adverse outcomes in the offspring.

Cost of developmental delay from prenatal exposure to airborne polycyclic aromatic hydrocarbons.

Early life exposure to ambient polycyclic aromatic hydrocarbons (PAHs) can result in developmental delay. The negative health effects of PAHs have been well-documented but the cost of developmental delay due to PAH exposure has not been studied. The Columbia Center for Children's Environmental Health previously has reported the significant effect of prenatal exposure to ambient PAHs on delayed mental development at three years, using the Bayley Scales in a cohort of low-income women and children in New York City (NYC). Here we have used the cohort results to estimate the annual costs of preschool special education services for low-income NYC children with developmental delay due to PAH exposure using the Environmentally Attributable Fraction method. The estimated cost of PAH-exposure-related services is over $13.7 million per year for Medicaid births in NYC. This high cost supports policies to reduce level of PAHs in NYC air.

Educational attainment and smoking among women: risk factors and consequences for offspring.

We examine the association between education and smoking by women in the population, including smoking during pregnancy, and identify risk factors for smoking and the consequences of smoking in pregnancy for children's smoking and behavioral problems. Secondary analyses of four national data sets were implemented: The National Survey of Drug Use and Health (2006), the National Longitudinal Survey of Youth (1979-2004); the National Longitudinal Survey of Adolescent Health (Wave III); National Health and Nutrition Examination Survey (2005-2006). The lower the level of education, the greater the risk of being a current smoker, smoking daily, smoking heavily, being nicotine dependent, starting to smoke at an early age, having higher levels of circulating cotinine per cigarettes smoked, and continuing to smoke in pregnancy. The educational gradient is especially strong in pregnancy. Educational level and smoking in pregnancy independently increase the risk of offspring smoking and antisocial and anxious/depressed behavior problems. These effects persist with control for other covariates, except maternal age at child's birth, which accounts for the impact of education on offspring smoking and anxious/depressed behavior problems. Women with low education should be the target of public health efforts toward reducing tobacco use. These efforts need to focus as much on social conditions that affect women's lives as on individual level interventions. These interventions would have beneficial effects not only for the women themselves but also for their offspring.
