ABSTRACT

Tuberculosis (TB) is a leading infectious killer worldwide. We systematically searched the National Institutes of Health Research, Portfolio Online Reporting Tools Expenditures and Results (RePORTER) website to compare research funding for key TB comorbidities-undernutrition, alcohol use, human immunodeficiency virus, tobacco use, and diabetes-and found a large mismatch between the population attributable fraction of these risk factors and the funding allocated to them.

ABSTRACT

Objective: To qualitatively explore the impact of anti-Asian racism in a Chinese community in the greater Boston area. Methods: Individual semi-structured interviews (n = 27) were conducted between June and September 2021. Eligible participants were ethnic Chinese immigrants living in the Boston area, who were recruited through a community-based organization and by word-of-mouth. Interviews were conducted in Mandarin and Cantonese and translated into English. Data were coded and analyzed using a directed approach to content analysis. Results: The majority of participants reported personal experiences of anti-Asian racism, ranging from microaggressions to violent attacks. Although lockdown and isolation during COVID-19 affected all communities, the Chinese community suffered unique and prolonged trauma stemming from the fear of violent attacks against Asians. The older person/people, in particular, were severely isolated due to fear of exposure to anti-Asian hate crimes. Participants reported a variety of emotional, mental, and physical health effects associated with feelings of fear, anxiety, isolation, and powerlessness. Many preferred to engage in self-protective behavior changes rather than relying on external resources. Conclusion: Participants advocated for more education, community, and governmental support, and increased allyship between communities of color. These findings provide cultural context on the trauma this population faces and can inform further actions to address the wide range of reported health effects.

ABSTRACT

Objective: Hospital employees are at risk of SARS-CoV-2 infection through transmission in 3 settings: (1) the community, (2) within the hospital from patient care, and (3) within the hospital from other employees. We evaluated probable sources of infection among hospital employees based on reported exposures before infection. Design: A structured survey was distributed to participants to evaluate presumed COVID-19 exposures (ie, close contacts with people with known or probable COVID-19) and mask usage. Participants were stratified into high, medium, low, and unknown risk categories based on exposure characteristics and personal protective equipment. Setting: Tertiary-care hospital in Boston, Massachusetts. Participants: Hospital employees with a positive SARS-CoV-2 PCR test result between March 2020 and January 2021. During this period, 573 employees tested positive, of whom 187 (31.5%) participated. Results: We did not detect a statistically significant difference in the proportion of employees who reported any exposure (ie, close contacts at any risk level) in the community compared with any exposure in the hospital, from either patients or employees. In total, 131 participants (70.0%) reported no known high-risk exposure (ie, unmasked close contacts) in any setting. Among those who could identify a high-risk exposure, employees were more likely to have had a high-risk exposure in the community than in both hospital settings combined (odds ratio, 1.89; P = .03). Conclusions: Hospital employees experienced exposure risks in both community and hospital settings. Most employees were unable to identify high-risk exposures prior to infection. When respondents identified high-risk exposures, they were more likely to have occurred in the community.

ABSTRACT

OBJECTIVE: To examine food access, dietary intake, and perceptions about diet and associations with health among adults on probation. DESIGN: Using a mixed-methods approach, interviews were used to understand food access, dietary intake, and diet and associations with health. A survey measured self-assessed diet quality and diet and associations with health. SETTING: One probation office in Rhode Island. PARTICIPANTS: English-speaking adults on probation in 2016 (n = 22 interviews, n = 304 surveys). MAIN OUTCOME MEASURE(S): Food access, dietary intake, knowledge about diet and health, and perceptions about healthy food. ANALYSIS: We used a thematic analytic approach to analyze the interviews. Descriptive statistics were performed for the survey. RESULTS: Many interviewees had inadequate food access, although most participated in the Supplemental Nutrition Assistance Program, and some received food from food banks. Interviewees primarily shopped at grocery stores and prepared food at home, and dietary intakes did not meet the 2020-2025 Dietary Guidelines for Americans. Almost two-thirds (64.2%) of survey participants reported good or fair diet quality. Based on the survey results, the majority of participants strongly agreed and agreed with the statements, "The types of foods I eat affect my health" and "The types of food I eat affect my weight." CONCLUSIONS AND IMPLICATIONS: This study identified low-quality dietary intake and food acquisition strategies, such as shopping sales, buying bulk, and going to multiple stores, by US adults on probation to access food with limited resources. Participants reported interest in eating healthier foods and knew there was a connection between dietary intake and health. These data support addressing ways to improve food access and dietary quality, focusing on future programs and policies for this population.

ABSTRACT

Despite progress on population-level HIV viral suppression, unknown outcomes amongst people who have initiated antiretroviral therapy (ART) in low- and middle-income countries, commonly referred to as loss to follow-up (LTFU), remains a barrier. The mean global estimate of LTFU is 20%, exceeding the World Health Organization target of <15%. Pervasive predictors associated with LTFU include younger age, low body mass index, low CD4 count, advanced HIV clinical stage and certain ART regimens. In Namibia, ART use by eligible individuals exceeds 85%, surpassing the global average. Nonetheless, LTFU remains a barrier to achieving viral suppression and requires research to elucidate context-specific factors. An observational cohort study was conducted in Namibia in 2012 by administering surveys to individuals who presented for HIV care and initiated ART for the first time. Additional data were collected from routine medical data monitoring systems. Participants classified as LTFU at 12 months were traced to confirm their status. Predictors of LTFU were analyzed using multivariable logistic regression. Of those who presented consecutively to initiate ART, 524 were identified as eligible to enroll in the study, 497 enrolled, and 474 completed the baseline questionnaire. The cohort had mean age 36 years, 39% were male, mean CD4 cell count 222 cells/mm3, 17% were WHO HIV clinical stage III-IV, and 14% started efavirenz-based regimens. Tracing participants classified as LTFU yielded a re-categorization from 27.8% (n = 132) to 14.3% (n = 68) LTFU. In the final multivariable model, factors associated with confirmed LTFU status were: younger age (OR 0.97, 95% CI 1.00-1.06, p = 0.02); male sex (OR 2.34, CI 1.34-4.06, p = 0.003); difficulty leaving work or home to attend clinic (OR 2.55, CI 1.40-4.65, p = 0.002); and baseline efavirenz-based regimen (OR 2.35, CI 1.22-4.51, p = 0.01). Interventions to reduce LTFU should therefore target young men, particularly those who report difficulty leaving work or home to attend clinic and are on an efavirenz-based regimen.

ABSTRACT

To support optimal third-line antiretroviral therapy (ART) selection in Namibia, we investigated the prevalence of HIV drug resistance (HIVDR) at time of failure of second-line ART. A cross-sectional study was conducted between August 2016 and February 2017. HIV-infected people ≥15 years of age with confirmed virological failure while receiving ritonavir-boosted protease inhibitor (PI/r)-based second-line ART were identified at 15 high-volume ART clinics representing over >70% of the total population receiving second-line ART. HIVDR genotyping of dried blood spots obtained from these individuals was performed using standard population sequencing methods. The Stanford HIVDR algorithm was used to identify sequences with predicted resistance; genotypic susceptibility scores for potential third-line regimens were calculated. Two hundred thirty-eight individuals were enrolled; 57.6% were female. The median age and duration on PI/r-based ART at time of enrolment were 37 years and 3.46 years, respectively. 97.5% received lopinavir/ritonavir-based regimens. The prevalence of nucleoside reverse transcriptase inhibitor (NRTI), non-nucleoside reverse transcriptase inhibitor (NNRTI), and PI/r resistance was 50.6%, 63.1%, and 13.1%, respectively. No significant association was observed between HIVDR prevalence and age or sex. This study demonstrates high levels of NRTI and NNRTI resistance and moderate levels of PI resistance in people receiving PI/r-based second-line ART in Namibia. Findings underscore the need for objective and inexpensive measures of adherence to identify those in need of intensive adherence counselling, routine viral load monitoring to promptly detect virological failure, and HIVDR genotyping to optimize selection of third-line drugs in Namibia.

ABSTRACT

Since 2009, mid-upper arm circumference (MUAC) has become an accepted measure for screening children for acute malnutrition and determining eligibility for services to manage acute malnutrition. Use of MUAC has increased the reach and enhanced the quality of community-based management of acute malnutrition services. Increasingly, MUAC is also used to assess nutritional status and eligibility for nutrition support among adolescents and adults, including pregnant and lactating women and HIV and TB clients. However, globally recognised cut-offs have not been established to classify malnutrition among adults using MUAC. Therefore, different countries and programmes use different MUAC cut-offs to determine eligibility for programme services. Patient monitoring guidelines provided by WHO for country adaptation to support the integrated management of adult illness do not include MUAC, in part because guidance does not exist about what MUAC cut-off should trigger further action.

ABSTRACT

OBJECTIVE: To determine if a global mid-upper arm circumference (MUAC) cut-off can be established to classify underweight in adults (men and non-pregnant women). DESIGN: We conducted an individual participant data meta-analysis (IPDMA) to explore the sensitivity (SENS) and specificity (SPEC) of various MUAC cut-offs for identifying underweight among adults (defined as BMI < 18·5 kg/m2). Measures of diagnostic accuracy were determined every 0·5 cm across MUAC values from 19·0 to 26·5 cm. A bivariate random effects model was used to jointly estimate SENS and SPEC while accounting for heterogeneity between studies. Various subgroup analyses were performed. SETTING: Twenty datasets from Africa, South Asia, Southeast Asia, North America and South America were included. PARTICIPANTS: All eligible participants from the original datasets were included. RESULTS: The total sample size was 13 835. Mean age was 32·6 years and 65 % of participants were female. Mean MUAC was 25·7 cm, and 28 % of all participants had low BMI (<18·5 kg/m2). The area under the receiver operating characteristic curve for the pooled dataset was 0·91 (range across studies 0·61-0·98). Results showed that MUAC cut-offs in the range of ≤23·5 to ≤25·0 cm could serve as an appropriate screening indicator for underweight. CONCLUSIONS: MUAC is highly discriminatory in its ability to distinguish adults with BMI above and below 18·5 kg/m2. This IPDMA is the first step towards determining a global MUAC cut-off for adults. Validation studies are needed to determine whether the proposed MUAC cut-off of 24 cm is associated with poor functional outcomes.

ABSTRACT

The aim of this study was to determine the prevalence and risk factors of the main enteric parasitic infections that affect children and dogs in the municipality of Ilhéus, Bahia, Brazil; and to identify the geopolitical areas that should receive priority interventions to combat them. Between March and November 2016, fecal samples of 143 dogs and 193 children aged 1 month to 5 years were collected in 40 rural and semirural communities using a systematic sampling approach, stratified by district. Samples were collected by legal guardians of the children and / or dog owners. Eggs, larvae, cysts and oocysts of parasites were concentrated by centrifugal-flotation and centrifugal-sedimentation, and acid-resistant staining was used to visualize parasites. One hundred and thirty-two children (68.4%), 111 dogs (77.6%) and 199 (73.7%) dog fecal samples collected from streets were parasitized. Giardiasis, cryptosporidiosis, amoeba infections and hookworm were the most frequent infections in all studied populations, in addition to trichuriasis in dogs and ascaridiasis in children. A predominance of Giardia and hookworms was observed in children and dogs, respectively. The coastal districts of Aritaguá, Olivença and the main district had a higher parasitic diversity and overlapping of important potential zoonotic infections. Age over one year (p<0.001), adjusted OR = 3.65; 95% CI = 1.86-7.16) and income below the minimum monthly salary (p = 0.02, adjusted OR = 2.78, 95% CI = 1.17-6.59) were the main factors associated with intestinal parasitic infections in children and dogs, respectively. The coastal districts of Aritaguá and Olivença and the main district should be prioritized through enteric disease control programs, and the factors associated with infections must be considered in the design of health interventions in these districts. The integration between affirmative income actions and investments to improve the health infrastructure of these communities may work more effectively than current preventive measures to combat enteric parasites.

ABSTRACT

BACKGROUND: Fueled by the burgeoning opioid epidemic, valve surgeries for substance use disorder-related infective endocarditis (SUD-IE) are increasing. The impact of substance use disorder on postvalve replacement morbidity needs further investigation. METHODS: We queried The Society of Thoracic Surgeons Adult Cardiac Surgery Database for all valve surgeries for infective endocarditis at Tufts Medical Center (2002-2016) and collected demographic and disease-related data, including timing of mortality subclassified as short-term (<6 months including operative), midterm (6 months to 5 years), and extended-term (>5 years). Patients with documentation of illicit drug use before the operation were considered to have SUD-IE. Deaths were confirmed through review of medical record and matching with the Massachusetts Vital Statistics Database. We performed univariate and multivariate proportional hazard regressions examining the impact of substance use disorder mortality in people who received a valve replacement. RESULTS: In the cohort of 228 patients, 80 (35%) had SUD-IE. Eight-six people (38%) died, and overall mortality was higher in people with SUD-IE compared with non-SUD-IE (48% vs 32%, P = .025). SUD-IE was associated with a higher risk of overall mortality (adjusted hazard ratio, 2.41; 95% confidence interval, 1.38-4.20; P = .002). Although the difference between short-term or extended-term mortality was not significant, SUD-IE was associated with increased frequency of midterm mortality (53% vs 31%, P = .003). CONCLUSIONS: Our data reflect high rates of postvalve surgery morbidity and mortality in people with SUD-IE at a tertiary care center. The midterm postoperative period is a vulnerable period for people with SUD-IE worthy of further investigation.

ABSTRACT

Mobile phones are increasingly being used to support health activities, including the care and management of people living with HIV/AIDS. Short message service (SMS) has been explored as a means to optimize and support behaviour change. However, there is minimal guidance on messaging content development. The purpose of this review was to inform the content of SMS messages for mobile health (mHealth) initiatives designed to support anti-retroviral therapy adherence and clinic appointment keeping in resource-limited settings. PubMed, OvidMedline, Google Scholar, K4Health's mHealth Evidence database, the mHealth Working Group project resource, and Health COMpass were searched. A request to online communities for recommendations on message content was also made. 1010 unique sources were identified, of which 51 were included. The information was organized into three categories: pre-message development, message development, and security and privacy. Fifteen of the publications explicitly provided their message content. Important lessons when developing the content of SMS were: (1) conducting formative research; (2) grounding content in behaviour change theory; and (3) reviewing proposed content with experts. Best practices exist for developing message content for behaviour change. Efforts should be continued to apply lessons learned from the existing literature to inform mHealth initiatives supporting HIV/AIDS care and treatment.

ABSTRACT

When individuals are on probation, they face challenges with securing employment and safe housing due to their criminal records, which may make food access problematic. Food insecurity is a construct used as a marker for food access that considers financial constraints and has been associated with poorer health and substance use. There is limited research on the extent of food insecurity and associated morbidities and substance use among adults on probation. We conducted a cross-sectional study in 2016, surveying 304 probationers in Rhode Island to determine whether food insecurity is associated with obesity, high blood pressure, depression, and substance use. Separate logistic regression models were used to determine the associations between food insecurity and obesity, high blood pressure, depression, and substance use. Food insecurity was experienced by 70% of our study population. The estimated prevalence of high blood pressure was significantly higher in our study sample compared to the general US population. Food insecurity was not associated with obesity, high blood pressure, or current drug use in this study sample. Food insecurity was independently associated with more than three times greater odds of being depressed (AOR 3.33, 95%CI 1.89, 5.86) and a nearly twofold greater odds of self-reporting a lower health status (AOR 1.91, 95%CI 1.18, 3.10) after adjusting for gender, race/ethnicity, age, income categories, and being homeless. Probationers were found to have a higher estimated prevalence of high blood pressure and food insecurity compared to the general population, which highlights the health disparities faced by this population. Our findings have important implications for future research and interventions to decrease the health burden not only on the individuals but their families and communities.

ABSTRACT

BACKGROUND: Individuals under community corrections supervision may be at increased risk for food insecurity because they face challenges similar to other marginalized populations, such as people experiencing housing instability or substance users. The prevalence of food insecurity and its correlates have not been studied in the community corrections population. METHODS: We conducted a cross-sectional study in 2016, surveying 304 probationers in Rhode Island to estimate the prevalence of food insecurity, identify food acquisition methods, and determine characteristics of groups most at-risk for food insecurity. We used chi-square and Fisher's exact tests to assess differences in sociodemographics and eating and food acquisition patterns, GIS to examine geospatial differences, and ordinal logistic regression to identify independent correlates across the four levels of food security. RESULTS: Nearly three-quarters (70.4%) of the participants experienced food insecurity, with almost half (48.0%) having very low food security. This is substantially higher than the general population within the state of Rhode Island, which reported a prevalence of 12.8% food insecurity with 6.1% very low food security in 2016. Participants with very low food security most often acquired lunch foods from convenience stores (and less likely from grocery stores) compared to the other three levels of food security. Participants did not differ significantly with regards to places for food acquisition related to breakfast or dinner meals based upon food security status. In adjusted models, being homeless (AOR 2.34, 95% CI: 1.31, 4.18) and depressed (AOR 3.12, 95% CI: 1.98, 4.91) were independently associated with a greater odds of being in a food insecure group. Compared to having help with meals none of the time, participants who reported having meal help all of the time (AOR 0.28, 95% CI: 0.12, 0.64), most of the time (AOR 0.31, 95% CI: 0.15, 0.61), and some of the time (AOR 0.54, 95% CI: 0.29, 0.98) had a lower odds of being in a food insecure group. Food insecure participants resided in different neighborhoods than food secure participants. The highest density of food insecure participants resided in census tracts with the lowest median incomes for the general population. The areas of highest density for each level of food security for our participants were in the census tracts with the lowest levels of full-time employment for the general population. CONCLUSIONS: The prevalence of food insecurity and very low food security were markedly higher in our probation population compared to the general RI population. These findings suggest that access to food on a regular basis is a challenge for adults on probation. Depression and being homeless were independently associated with a greater odds of being in a food insecure group. In addition to intervening directly on food insecurity, developing interventions and policies that address the contributing factors of food insecurity, such as safe housing and treatment for depression, are critical.

ABSTRACT

BACKGROUND: Individuals on probation experience economic disadvantage because their criminal records often prohibit gainful employment, which compromises their ability to access the basic components of wellbeing. Unemployment and underemployment have been studied as distinct phenomenon but no research has examined multiple determinants of health in aggregate or explored how these individuals prioritize each of these factors. This study identified and ranked competing priorities in adults on probation and qualitatively explored how these priorities impact health. METHODS: We conducted in-depth interviews in 2016 with 22 adults on probation in Rhode Island to determine priority rankings of basic needs. We used Maslow's hierarchy of needs theory and the literature to guide the priorities we pre-selected for probationers to rank. Within a thematic analysis framework, we used a modified ranking approach to identify the priorities chosen by participants and explored themes related to the top four ranked priorities. RESULTS: We found that probationers ranked substance use recovery, employment, housing, and food intake as the top four priorities. Probationers in recovery reported sobriety as the most important issue, a necessary basis to be able to address other aspects of life. Participants also articulated the interrelatedness of difficulties in securing employment, food, and housing; these represent stressors for themselves and their families, which negatively impact health. Participants ranked healthcare last and many reported underinsurance as an issue to accessing care. CONCLUSIONS: Adults on probation are often faced with limited economic potential and support systems that consistently place them in high-risk environments with increased risk for recidivism. These findings emphasize the need for policies that address the barriers to securing gainful employment and safe housing. Interventions that reflect probationer priorities are necessary to begin to mitigate the health disparities in this population.

ABSTRACT

BACKGROUND: Conflicting evidence exists regarding potential cardiovascular risks associated with high levels of calcium intake. PURPOSE: To update and reanalyze 2 systematic reviews to examine the effects of calcium intake on cardiovascular disease (CVD) among generally healthy adults. DATA SOURCES: MEDLINE; Cochrane Central Register of Controlled Trials; Scopus, including EMBASE; and previous evidence reports from English-language publications from 1966 to July 2016. STUDY SELECTION: Randomized trials and prospective cohort and nested case-control studies with data on dietary or supplemental intake of calcium, with or without vitamin D, and cardiovascular outcomes. DATA EXTRACTION: Study characteristics and results extracted by 1 reviewer were confirmed by a second reviewer. Two raters independently assessed risk of bias. DATA SYNTHESIS: Overall risk of bias was low for the 4 randomized trials (in 10 publications) and moderate for the 27 observational studies included. The trials did not find statistically significant differences in risk for CVD events or mortality between groups receiving supplements of calcium or calcium plus vitamin D and those receiving placebo. Cohort studies showed no consistent dose-response relationships between total, dietary, or supplemental calcium intake levels and cardiovascular mortality and highly inconsistent dose-response relationships between calcium intake and risks for total stroke or stroke mortality. LIMITATIONS: CVD disease outcomes were secondary end points in all trials. Dose-response metaregression analysis of cohort studies was limited by potential confounding, ecological bias, and imprecise measures of calcium exposures. Data were scarce regarding very high calcium intake-that is, beyond recommended tolerable upper intake levels. CONCLUSION: Calcium intake within tolerable upper intake levels (2000 to 2500 mg/d) is not associated with CVD risk in generally healthy adults. PRIMARY FUNDING SOURCE: National Osteoporosis Foundation.

ABSTRACT

OBJECTIVE: To validate a novel objective structured clinical examination (OSCE) tool for assessing neonatal care skills among delivery attendants trained as part of the Essential Care for Every Baby (ECEB) program and to assess ECEB training effectiveness. METHODS: Between August 1 and September 30, 2015, a cross-sectional study enrolled ECEB-trained healthcare providers who attended deliveries from the Brong Ahafo and Eastern regions of Ghana. Participants completed a previously developed 21-item OSCE tool that assessed neonatal-care competency. Participant performance was scored independently by regional trainers and national master trainers. The inter-rater scoring reliability was assessed using the Cohen kappa coefficient and performance was compared across participant characteristics. RESULTS: The study enrolled 57 trained delivery attendants from 12 district hospitals. Inter-rater agreement was perfect (kappa 1.00) or almost perfect (kappa 0.81-0.99) for nine OSCE items, substantial (kappa 0.61-0.80) or moderate (kappa 0.41-0.60) for 11 items, and fair (kappa 0.21-0.40) for one item. Differences in OSCE-item performance were recorded based on participants' regions, facility type, age, and education level (P<0.05). CONCLUSIONS: In a resource-limited setting, the OSCE tool demonstrated substantial reliability and ECEB-trained healthcare practitioners exhibited satisfactory performance. The OSCE tool could be useful in similar settings and could have potential for up-scaled use in assessing neonatal-management skills.

ABSTRACT

BACKGROUND & AIMS: HIV-infected adults have increased risk of several individual micronutrient deficiencies. However, the prevalence and risk factors of concurrent and multiple micronutrient deficiencies and whether micronutrient concentrations change after antiretroviral therapy (ART) initiation have not been well described. The objective of this study was to determine the prevalence and risk factors of individual, concurrent and multiple micronutrient deficiencies among ART-naïve HIV-infected adults from nine countries and assess change in micronutrient status 48 weeks post-ART initiation. METHODS: A random sub-cohort (n = 270) stratified by country was selected from the multinational PEARLS clinical trial (n = 1571 ART-naïve, HIV-infected adults). We measured serum concentrations of vitamins A, D (25-hydroxyvitamin), E, carotenoids and selenium pre-ART and 48 weeks post-ART initiation, and measured vitamins B6, B12, ferritin and soluble transferrin receptor at baseline only. Prevalence of single micronutrient deficiencies, concurrent (2 coexisting) or conditional (a deficiency in one micronutrient given a deficiency in another) and multiple (≥3) were determined using defined serum concentration cutoffs. We assessed mean changes in micronutrient concentrations from pre-ART to week 48 post-ART initiation using multivariable random effects models. RESULTS: Of 270 participants, 13.9%, 29.2%, 24.5% and 32.4% had 0, 1, 2 and multiple deficiencies, respectively. Pre-ART prevalence was the highest for single deficiencies of selenium (53.2%), vitamin D (42.4%), and B6 (37.3%) with 12.1% having concurrent deficiencies of all three micronutrients. Deficiency prevalence varied widely by country. 48 weeks post-ART initiation, mean vitamin A concentration increased (p < 0.001) corresponding to a 9% decrease in deficiency. Mean concentrations also increased for other micronutrients assessed 48 weeks post-ART (p < 0.001) but with minimal change in deficiency status. CONCLUSIONS: Single and multiple micronutrient deficiencies are common among HIV-infected adults pre-ART initiation but vary between countries. Importantly, despite increases in micronutrient concentrations, prevalence of individual deficiencies remains largely unchanged after 48 weeks on ART. Our results suggest that ART alone is not sufficient to improve micronutrient deficiency.

ABSTRACT

OBJECTIVES: To update a prior systematic review on the effects of omega-3 fatty acids (n-3 FA) on maternal and child health and to assess the evidence for their effects on, and associations with, additional outcomes. DATA SOURCES: MEDLINE®, Embase®, the Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Centre for Agriculture and Biosciences (CAB) Abstracts from 2000 to August 2015; eligible studies from the original report; and relevant systematic reviews. REVIEW METHODS: We included randomized controlled trials (RCTs) of any defined dose of n-3 FA (or combination) compared to placebo, any other n-3 FA, or alternative dose with an outcome of interest conducted in pregnant or breastfeeding women or neonates (preterm or term). We also included prospective observational studies that analyzed the association between baseline n-3 FA intake or biomarker level and followup outcomes. Postnatal interventions began within a week of birth for term infants and within a week of beginning enteral or oral feeding for preterm infants. Standard methods were used for data abstraction and analysis, according to the Evidence-based Practice Center Methods Guide. RESULTS: We identified 4,275 potentially relevant titles from our searches, of which 95 RCTs and 48 observational studies met the inclusion criteria. Risk of bias was a concern with both RCTs and observational studies. Outcomes for which evidence was sufficient to draw a conclusion are summarized here with the Strength of Evidence (SoE). (Outcomes for which the evidence was insufficient to draw a conclusion are summarized in Appendix G of the report.).Maternal Exposures and Outcomes: Gestational length and risk for preterm birth: Prenatal algal docosahexaenoic acid (DHA) or DHA-enriched fish oil supplementation had a small positive effect on length of gestation (moderate SoE), but no effect on risk for preterm birth (low SoE). Prenatal EPA (eicosapentaenoic acid) plus DHA-containing fish oil supplementation has no effect on length of gestation (low SoE). Supplementation with DHA, or EPA plus DHA-, or DHA-enriched fish oil does not decreaserisk for preterm birth (low SoE).Birth weight and risk for low birth weight: Changes in maternal n-3 FA biomarkers were significantly associated with birth weight. Prenatal algal DHA or DHA-enriched fish oil supplementation had a positive effect on birth weight among healthy term infants (moderate SoE), but prenatal DHA supplementation had no effect on risk for low birth weight (low SoE). Prenatal EPA plus DHA or alpha-linolenic acid (ALA) supplementation had no effect on birth weight (low SoE).Risk for peripartum depression: Maternal n-3 FA biomarkers had no association with risk for peripartum depression. Maternal DHA, EPA, or DHA-enriched fish oil supplementation had no effect on risk for peripartum depression (low SoE).Risk for gestational hypertension/preeclampsia: Prenatal DHA supplementation among high-risk pregnant women had no effect on the risk for gestational hypertension or preeclampsia (moderate SoE). Prenatal supplementation of any n-3 FA in normal-risk women also had no significant effect on risk for gestational hypertension or preeclampsia (low SoE).Fetal, Infant, and Child Exposures and Outcomes: Postnatal growth patterns: Maternal fish oil or DHA plus EPA supplementation had no effect on postnatal growth patterns (attainment of weight, length, and head circumference) when administered prenatally (moderate SoE) or both pre- and postnatally (low SoE). Fortification of infant formulas with DHA plus arachidonic acid (AA, an n-6 FA) had no effect on growth patterns of preterm or term infants (low SoE).Visual acuity: Prenatal supplementation with DHA had no effect on development of visual acuity (low SoE). Supplementing or fortifying preterm infant formula with any n-3 FA had no significant effect on visual acuity assessed by visual evoked potentials (VEP) at 4 or 6 months corrected age (low SoE). Data conflicted on the effectiveness of supplementing infant formula for term infants with n-3 FA depending on when and how visual acuity was assessed (i.e. by VEP or by behavioral methods) and the type of essential FA provided (low SoE).Neurological development: Prenatal or postnatal n-3 FA supplementation had no consistent effect on neurological development (low SoE).Cognitive development: Prenatal DHA supplementation with AA or EPA had no effect on cognitive development (moderate SoE). Supplementing breastfeeding women with DHA plus EPA also had no effect on cognitive development in infants and children (low SoE). Supplementing or fortifying preterm infants' formula with DHA plus AA had a positive effect on infant cognition at some short-term followup times (moderate SoE). Supplementing or fortifying infant formula for term infants with any n-3 FA had no effect on cognitive development (low SoE). Evidence is insufficient to support any effect of n-3 FA infant supplementation on long-term cognitive outcomes.Autism spectrum disorder, attention deficit hyperactivity disorder (ADHD), and learning disorders: Maternal or infant n-3 FA supplementation had no effect on risk for autism spectrum disorders or ADHD (low SoE). No studies on other learning disorders were identified.Atopic dermatitis (AD), allergies, and respiratory disorders: Pre- and postnatal (maternal and infant) n-3 FA supplementation had no consistent effect on the risk for AD/eczema, allergies, asthma, and other respiratory illnesses (moderate SoE). Biomarkers and intakes had no consistent association with the risk for AD, allergies, and respiratory disorders (low SoE).Adverse events: Prenatal and infant supplementation with n-3 FA or fortification of foods with n-3 FA did not result in any serious or nonserious adverse events (moderate SoE); with the exception of an increased risk for mild gastrointestinal symptoms. CONCLUSIONS: Most studies in this report examined the effects of fish oil (or other combinations of DHA and EPA) supplements on pregnant or breastfeeding women or the effects of infant formula fortified with DHA plus AA. As with the original report, with the exception of small increases in birth weight and length of gestation,n-3 FA supplementation or fortification has no consistent evidence of effects on peripartum maternal or infant health outcomes. No effects of n-3 FA were seen on gestational hypertension, peripartum depression, or postnatal growth. Apparent effects of n-3 FA supplementation were inconsistent across assessment methods and followup times for outcomes related to infant visual acuity, cognitive development and prevention of allergy and asthma. Future RCTs need to assess standardized preparations of n-3 and n-6 FA, using a select group of clinically important outcomes, on populations with baseline n-3 FA intakes typical of those of most western populations.
