Adaptive Viral Load Monitoring Frequency to Facilitate Differentiated Care: A Modeling Study From Rakai, Uganda.

BACKGROUND: After scale-up of antiretroviral therapy (ART), routine annual viral load monitoring has been adopted by most countries, but reduced frequency of viral load monitoring may offer cost savings in resource-limited settings. We investigated if viral load monitoring frequency could be reduced while maintaining detection of treatment failure. METHODS: The Rakai Health Sciences Program performed routine, biannual viral load monitoring on 2489 people living with human immunodeficiency virus (age ≥15 years). On the basis of these data, we built a 2-stage simulation model to compare different viral load monitoring schemes. We fit Weibull regression models for time to viral load >1000 copies/mL (treatment failure), and simulated data for 10 000 individuals over 5 years to compare 5 monitoring schemes to the current viral load testing every 6 months and every 12 months. RESULTS: Among 7 monitoring schemes tested, monitoring every 6 months for all subjects had the fewest months of undetected failure but also had the highest number of viral load tests. Adaptive schemes using previous viral load measurements to inform future monitoring significantly decreased the number of viral load tests without markedly increasing the number of months of undetected failure. The best adaptive monitoring scheme resulted in a 67% reduction in viral load measurements, while increasing the months of undetected failure by <20%. CONCLUSIONS: Adaptive viral load monitoring based on previous viral load measurements may be optimal for maintaining patient care while reducing costs, allowing more patients to be treated and monitored. Future empirical studies to evaluate differentiated monitoring are warranted.

Population-level adult mortality following the expansion of antiretroviral therapy in Rakai, Uganda.

There are limited data on the impact of antiretroviral therapy (ART) on population-level adult mortality in sub-Saharan Africa. We analysed data for 2000-14 from the Rakai Community Cohort Study (RCCS) in Uganda, where free ART was scaled up after 2004. Using non-parametric and parametric (Weibull) survival analysis, we estimated trends in average person-years lived between exact ages 15 and 50, per capita life-years lost to HIV, and the mortality hazards of people living with HIV (PLHIV). Between 2000 and 2014, average adult life-years lived before age 50 increased significantly, from 26.4 to 33.5 years for all women and from 28.6 to 33.8 years for all men. As of 2014, life-years lost to HIV had declined significantly, to 1.3 years among women and 0.4 years among men. Following the roll-out of ART, mortality reductions among PLHIV were initially larger in women than men, but this is no longer the case.

Caregiver versus self-reported activities of daily living among HIV-positive persons in Rakai, Uganda.

Assessment of an individual's functional status, as measured by activities of daily living (ADL), is an essential element in the diagnosis of HIV-associated neurocognitive disorders (HAND) but individuals with cognitive impairment may not accurately report ADL. We assessed agreement between self- and caregiver-reported ADL in HIV-positive persons. Antiretroviral therapy (ART)-naïve HIV-positive persons (n = 321) and HIV-negative controls (n = 134) in Rakai, Uganda, completed neurocognitive tests and an ADL questionnaire. Co-resident relatives ("caregivers") were independently administered the ADL questionnaire to determine their perception of the participant's ADL. The relationship between neurocognitive impairment and participant-caregiver agreement was assessed using kappa statistics. Regression was used to estimate adjusted prevalence ratios (AdjPR) of participant-caregiver agreement on disability scores. Relative to HIV-negative adults, HIV-positive participants scoring at least 1 standard deviation (SD) below the norm on 2 or more neurocognitive tests were classified as having mild neurocognitive impairment and those scoring at least 2 SD below the norm on 2 or more neurocognitive tests were classified as having moderate-to-severe. Mean age was 36 years (SD 8.9), and 53% of participants were male. The rate of ADL agreement between participants and caregivers was 77% for HIV-positive and 87% for HIV-negative participants (AdjPR = 0.89, 95% CI 0.81-0.97, p = .01). Among HIV-positive participants, 41% had moderate neurocognitive impairment, 15% had severe neurocognitive impairment, and 44% were normal. For moderate neurocognitive impairment, the rate of ADL agreement was 69% and for severe neurocognitive impairment, it was 66%. Compared to non-impaired HIV-positive participants (86% ADL agreement), ADL agreement was lower with moderate impairment (AdjPR = 0.89, 95%CI 0.81-0.98, p = .023) and severe impairment (AdjPR = 0.77, 95%CI 0.63-0.95, p = .014). Gender, education and CD4 count were not associated with ADL agreement. HIV-positive persons with neurocognitive impairment have lower agreement with caregivers' reports of ADL than HIV-positive persons without cognitive impairment.

Unfulfilled need for contraception among women with unmet need but with the intention to use contraception in Rakai, Uganda: a longitudinal study.

BACKGROUND: Longitudinal data from a rural Ugandan cohort was used to estimate rates of unfulfilled need for contraception, defined as having unmet need and intent to use contraception at baseline but having an unintended pregnancy or with persistent unmet need for contraception at follow up. METHODS: Between 2002 and 2009 (5 survey rounds), a total of 2610 sexually active non-pregnant women with unmet need for contraception at the start of an inter-survey period were asked whether they intended to use any method of contraception until they desired a child. Modified Poisson multivariate regression was used to estimate unadjusted and adjusted prevalence ratios (PR) and 95% CI of unfulfilled need for contraception. RESULTS: The proportion of women with unmet need at the start of an interval who intended to use contraception significantly increased from 61 to 69.1% (p < 0.05). However the majority of women who said they intended to use contraception had unfulfilled need for contraception at the subsequent survey (64.8 to 56.8%). In the adjusted analysis, significant predictors of unfulfilled need for contraception included age 40-49 years (PR = 1.34; 95% CI 1.04-1.74) and those with unknown HIV status (PR = 1.16; 95% CI 1.06-1.26). CONCLUSIONS: There is a significant discrepancy between women's intent to use contraception (> 60%) and subsequent initiation of use (< 30%) with many having unintended pregnancies which might explain the persistent high fertility in Uganda. Future research needs to address unfulfilled need for contraception among women at risk of unintended pregnancies.

Association between spousal emotional abuse and reproductive outcomes of women in India: findings from cross-sectional analysis of the 2005-2006 National Family Health Survey.

PURPOSE: Spousal violence against women is a global public health problem. In India, approximately 40% of women report spousal violence. Like physical and sexual violence, emotional violence may be a determinant of women's health. This study explores the association between exposure to spousal emotional abuse and poor reproductive outcomes in Indian women. METHODS: Data on 60,350 women, collected in the Third Indian National Family Health Survey were analysed to assess the impact of spousal emotional abuse on seven reproductive outcomes: age at first birth, number of children, terminated pregnancies, unwanted pregnancies, access to prenatal and skilled delivery care, and breastfeeding. Spousal emotional abuse was assessed using two overlapping constructs: emotional violence and controlling behaviour. Multivariable logistic regression was used for analysis. RESULTS: Spousal emotional violence and controlling behaviour was reported by 16 and 38% of the women, respectively. In unadjusted analyses, spousal emotional violence was associated with all adverse reproductive outcomes, except breastfeeding. Controlling for socio-demographic risk factors attenuated the association, and further adjustment for other forms of violence removed all significant associations. Spousal controlling behaviour was significantly associated with all outcomes, except breastfeeding. The effects remained statistically significant in multivariable regression. CONCLUSIONS: Women's experience of violence may be under-reported. When other forms of violence were adjusted for, emotional violence was not associated with adverse reproductive outcomes, whereas controlling behaviour remained associated with all but one adverse reproductive outcome. Therefore, spousal controlling behaviour requires further investigation as a determinant of reproductive health.

Dietary Patterns and Alcohol Consumption During Pregnancy: Secondary Analysis of Avon Longitudinal Study of Parents and Children.

BACKGROUND: Large general population surveys show that heavy regular and episodic alcohol consumption are associated with lower intakes of fruits and vegetables, and higher intakes of processed and fried meat. This is of particular concern regarding pregnant women, as both alcohol intake and inadequate maternal nutrition are independently associated with adverse fetal outcomes. The current study aimed to determine associations between maternal dietary patterns and alcohol consumption during pregnancy. METHODS: Women were participating in the Avon Longitudinal Study of Parents and Children, and provided details of alcohol consumption at 18 weeks' gestation and diet at 32 weeks' gestation (n = 9,839). Dietary patterns were derived from the food frequency questionnaire data using principal components analysis. Associations between alcohol consumption and dietary patterns were determined using multiple linear regression, adjusted for various sociodemographic and lifestyle factors. RESULTS: After adjustment, drinking ≥1 unit/d during the first trimester (ß = 0.23 [95% CI: 0.08, 0.38]; p = 0.002) and binge drinking (≥4 units in 1 day) during the first half of pregnancy (ß = 0.14 [95% CI: 0.07, 0.21]; p < 0.0001) were associated with greater adherence to the "Processed" dietary pattern (high intakes of processed meat and low intakes of fruit and vegetables). Light-to-moderate alcohol consumption (≤1 drink/d) during the first trimester was associated with greater adherence to the "Health conscious" dietary pattern (high intakes of fruit, vegetables, whole grains, and fish) (ß = 0.09 [95% CI: 0.04, 0.14]; p < 0.0001). CONCLUSIONS: Two important components of health behavior during pregnancy appear to be related: greater consumption of processed foods associated with heavier alcohol consumption, and healthier dietary choices associated with light-to-moderate alcohol intake. Potential synergistic effects of these behaviors may have implications for maternal and fetal health and warrant further investigation. A more holistic approach to addressing health behaviors in women of reproductive age is required.

Rates of switching to second-line antiretroviral therapy and impact of delayed switching on immunologic, virologic, and mortality outcomes among HIV-infected adults with virologic failure in Rakai, Uganda.

BACKGROUND: Switch from first to second-line ART is recommended by WHO for patients with virologic failure. Delays in switching may contribute to accumulated drug resistance, advanced immunosuppression, increased morbidity and mortality. The 3rd 90' of UNAIDS 90:90:90 targets 90% viral suppression for persons on ART. We evaluated the rate of switching to second-line antiretroviral therapy (ART), and the impact of delayed switching on immunologic, virologic, and mortality outcomes in the Rakai Health Sciences Program (RHSP) Clinical Cohort Study which started providing ART in 2004 and implemented 6 monthly routine virologic monitoring beginning in 2005. METHODS: Retrospective cohort study of HIV-infected adults on first-line ART who had two consecutive viral loads (VLs) >1000 copies/ml after 6 months on ART between June 2004 and June 2011 was studied for switching to second-line ART. Immunologic decline after virologic failure was defined as decrease in CD4 count of ≥50 cells/ul and virologic increase was defined as increase of 0.5 log 10 copies/ml. Competing risk models were used to summarize rates of switching to second-line ART while cox proportional hazard marginal structural models were used to assess the risk of virologic increase or immunologic decline associated with delay to switch first line ART failing patients. RESULTS: The cumulative incidence of switching at 6, 12, and 24 months following virologic failure were 30.2%, 44.6%, and 65.0%, respectively. The switching rate was increased with higher VL at the time of virologic failure; compared to those with VLs ≤ 5000 copies/ml, patients with VLs = 5001-10,000 copies/ml had an aHR = 1.81 (95% CI = 0.9-3.6), and patients with VLs > 10,000 copies/ml had an aHR = 3.38 (95%CI = 1.9-6.2). The switching rate was also increased with CD4 < 100 cells/ul at ART initiation, compared to those with CD4 ≥ 100 cells/ul (aHR = 2.30, 95% CI = 1.5-3.6). Mortality in patients not switched to second-line ART was 11.9%, compared to 1.2% for those who switched (p = 0.009). Patients switched after 12 months of of virologic failure were more likely to experience CD4 decline and/or further VL increases. CONCLUSIONS: Intervention strategies that aid clinicians to promptly switch patients to second-line ART as soon as virologic failure on 1st line ART is confirmed should be prioritized.

Moderate alcohol drinking in pregnancy increases risk for children's persistent conduct problems: causal effects in a Mendelian randomisation study.

BACKGROUND: Heavy alcohol use during pregnancy can cause considerable developmental problems for children, but effects of light-moderate drinking are uncertain. This study examined possible effects of moderate drinking in pregnancy on children's conduct problems using a Mendelian randomisation design to improve causal inference. METHODS: A prospective cohort study (ALSPAC) followed children from their mother's pregnancy to age 13 years. Analyses were based on 3,544 children whose mothers self-reported either not drinking alcohol during pregnancy or drinking up to six units per week without binge drinking. Children's conduct problem trajectories were classified as low risk, childhood-limited, adolescence-onset or early-onset-persistent, using six repeated measures of the Strengths and Difficulties Questionnaire between ages 4-13 years. Variants of alcohol-metabolising genes in children were used to create an instrumental variable for Mendelian randomisation analysis. RESULTS: Children's genotype scores were associated with early-onset-persistent conduct problems (OR = 1.29, 95% CI = 1.04-1.60, p = .020) if mothers drank moderately in pregnancy, but not if mothers abstained from drinking (OR = 0.94, CI = 0.72-1.25, p = .688). Children's genotype scores did not predict childhood-limited or adolescence-onset conduct problems. CONCLUSIONS: This quasi-experimental study suggests that moderate alcohol drinking in pregnancy contributes to increased risk for children's early-onset-persistent conduct problems, but not childhood-limited or adolescence-onset conduct problems.

Development and validation of a parent-report measure for detection of cognitive delay in infancy.

AIM: To develop a brief, parent-completed instrument (ERIC - Early Report by Infant Caregivers) for detection of cognitive delay in 10- to 24-month-olds born preterm, or of low birthweight, or with perinatal complications, and to establish ERIC's diagnostic properties. METHOD: Scores for ERIC were collected from the parents of 317 children meeting ≥inclusion criterion (birthweight <1500 g, gestational age <34 completed weeks, 5 min Apgar score <7, or presence of hypoxic-ischaemic encephalopathy) and no exclusion criteria. Children were assessed using a criterion score of below 80 on the Bayley Scales of Infant and Toddler Development-III cognitive scale. Items were retained according to their individual associations with delay. Sensitivity, specificity, and positive and negative predictive values were estimated and a truncated ERIC was developed for use in children <14 months old. RESULTS: ERIC correctly detected developmental delay in 17 out of 18 children in the sample, with 94.4% sensitivity, 76.9% specificity, 19.8% positive predictive value, 99.6% negative predictive value, 4.09 likelihood ratio positive, and 0.07 likelihood ratio negative. INTERPRETATION: ERIC has potential value as a quickly administered diagnostic instrument for the absence of early cognitive delay in 10- to 24-month-old preterm infants and as a screen for cognitive delay.

Systematic review of heath care interventions to improve outcomes for women with disability and their family during pregnancy, birth and postnatal period.

BACKGROUND: Health care providers are often unfamiliar with the needs of women with disability. Moreover maternity and postnatal services may not be specifically tailored to the needs of women with disability and their families. We conducted a systematic review to determine the effectiveness of healthcare interventions to improve outcomes for pregnant and postnatal women with disability and for their families. METHODS: Studies on pregnant and postnatal women with disability and their families which evaluated the effectiveness of an intervention using a design that met the criteria used by the Cochrane Effective Practice and Organization of Care group were eligible for inclusion in this review. A comprehensive search strategy was carried using eleven electronic databases. No restriction on date or language was applied. Included studies were assessed for quality and their results summarized and tabulated. RESULTS: Only three studies fully met the inclusion criteria. All were published after 1990, and conducted as small single-centre randomized controlled trials. The studies were heterogeneous and not comparable. Therefore the main finding of this review was the lack of published research on the effectiveness of healthcare interventions to improve outcomes for pregnant women with disability and their families. CONCLUSIONS: More research is required to evaluate healthcare interventions to improve outcomes for pregnant women with disability and their families.

Prenatal exposure to binge pattern of alcohol consumption: mental health and learning outcomes at age 11.

The objective of the study is to investigate whether episodic binge pattern of alcohol consumption during pregnancy is independently associated with child mental health and academic outcomes. Using data from the prospective, population-based Avon Longitudinal Study of Parents and Children (ALSPAC), we investigated the associations between binge patterns of alcohol consumption during pregnancy (≥4 drinks per day) and child mental health [as rated by both parent (n = 4,610) and teacher (n = 4,274)] and academic outcomes [based on examination results (n = 6,939)] at age 11 years. After adjusting for prenatal and postnatal risk factors, binge pattern of alcohol consumption (≥4 drinks in a day on at least one occasion) during pregnancy was associated with higher levels of mental health problems (especially hyperactivity/inattention) in girls at age 11 years, according to parental report. After disentangling binge-pattern and daily drinking, binge-pattern drinking was independently associated with teacher-rated hyperactivity/inattention and lower academic scores in both genders. Episodic drinking involving ≥4 drinks per day during pregnancy may increase risk for child mental health problems and lower academic attainment even if daily average levels of alcohol consumption are low. Episodic binge pattern of drinking appears to be a risk factor for these outcomes, especially hyperactivity and inattention problems, in the absence of daily drinking.

Women with disability: the experience of maternity care during pregnancy, labour and birth and the postnatal period.

BACKGROUND: It has been estimated that 9.4% of women giving birth in the United Kingdom have one or more limiting longstanding illness which may cause disability, affecting pregnancy, birth and early parenting. No large scale studies on a nationally representative population have been carried out on the maternity experiences of disabled women to our knowledge. METHOD: Secondary analysis of data from a survey of women in 2010 by English National Health Service Trusts on behalf of the Care Quality Commission was undertaken. 144 trusts in England took part in the postal survey.Women self-identified with disability and were excluded if less than 16 years of age or if their baby had died. The 12 page structured questionnaire with sections on antenatal, labour and birth and postnatal care covered access, information, communication and choice. Descriptive and adjusted analyses compared disabled and non-disabled groups. Comparisons were made separately for five disability subgroups: physical disability, sensory impairment, mental health conditions, learning disability and women with more than one type of disability. RESULTS: Disabled women comprised 6.14% (1,482) of the total sample (24,155) and appeared to use maternity services more than non-disabled women. Most were positive about their care and reported sufficient access and involvement, but were less likely to breastfeed. The experience of women with different types of disability varied: physically disabled women used antenatal and postnatal services more, but had less choice about labour and birth; the experience of those with a sensory impairment differed little from the non-disabled women, but they were more likely to have met staff before labour; women with mental health disabilities also used services more, but were more critical of communication and support; women with a learning disability and those with multiple disabilities were least likely to report a positive experience of maternity care. CONCLUSION: This national study describes disabled women's experiences of pregnancy, child birth and postnatal care in comparison with non-disabled women. While in many areas there were no differences, there was evidence of specific groups appropriately receiving more care. Areas for improvement included infant feeding and better communication in the context of individualised care.

Prevalence and impact of disability in women who had recently given birth in the UK.

BACKGROUND: Maternity services should take into account the needs of all women, including those related to disability. No reliable information, however, exists on the extent and characteristics of disability in this population in the UK. This brief report provides an overview of the prevalence of disability in women giving birth in the UK as measured by the presence of a limiting longstanding illness (LLI). The demographic, socio-economic, lifestyle and pregnancy related characteristics and child health outcomes are summarised to inform maternity and postnatal care service planning, and policy development. METHODS: Secondary analysis of data on 18,231 mother-child pairs from the nationally representative UK Millennium Cohort Study. The baseline interviews with families were carried out in 2001-2002. The LLI prevalence in women who had recently delivered was estimated, and relevant characteristics and differences in outcomes compared using descriptive statistics taking into account the study design and non-response. RESULTS: 9.4% (95% CI 8.7-10.0) of women who had recently given birth reported having an LLI. Musculoskeletal, respiratory and mental disorders accounted for most of the health problems. A significantly higher proportion of women with an LLI received means-tested financial benefits, had no educational qualifications and suffered from intimate partner violence compared to women who did not have an LLI (49.3% vs 35.3%, 20.4% vs 15.0%, 6.0% vs 3.3%, respectively). They were also more likely to smoke throughout pregnancy than women without an LLI (29.2% vs 20.8%), have a preterm birth (10.9% vs 6.8%) and be lone parents (19.5% vs 13.9%). Only 25.6% of children of mothers with an LLI were breastfed for more than three months compared to 33.4% of infants of mothers who did not have an LLI. At the age of seven years, 12.0% of children of mothers with an LLI had an activity limiting health problem themselves compared to 6.2% of children of mothers without an LLI. CONCLUSIONS: Disability in women who had recently delivered is relatively common. It is associated with social and economic inequalities and worse pregnancy and child related outcomes. Apart from condition-specific support during and after pregnancy, disabled women may require extra help from health professionals to quit smoking, continue breastfeeding, and reduce intimate partner violence.

A non-synonymous variant in ADH1B is strongly associated with prenatal alcohol use in a European sample of pregnant women.

Pregnant women are advised to abstain from alcohol despite insufficient evidence on the fetal consequences of moderate prenatal alcohol use. Mendelian randomization could help distinguish causal effects from artifacts due to residual confounding and measurement errors; however, polymorphisms reliably associated with alcohol phenotypes are needed. We aimed to test whether alcohol dehydrogenase (ADH) gene variants were associated with alcohol use before and during pregnancy. Ten variants in four ADH genes were genotyped in women from South-West England. Phenotypes of interest were quantity and patterns of alcohol consumption before and during pregnancy, including quitting alcohol following pregnancy recognition. We tested single-locus associations between genotypes and phenotypes with regression models. We used Bayesian models (multi-locus) to take account of linkage disequilibrium and reanalyzed the data with further exclusions following two conservative definitions of 'white ethnicity' based on the woman's reported parental ethnicity or a set of ancestry-informative genetic markers. Single-locus analyses on 7410 women of white/European background showed strong associations for rs1229984 (ADH1B). Rare allele carriers consumed less alcohol before pregnancy [odds ratio (OR) = 0.69; 95% confidence interval (CI): 0.56-0.86, P = 0.001], were less likely to have 'binged' during pregnancy (OR = 0.55, 95% CI: 0.38-0.78, P = 0.0009), and more likely to have abstained in the first trimester of gestation (adjusted OR = 1.42, 95% CI: 1.12-1.80, P = 0.004). Multi-locus models confirmed these results. Sensitivity analyses did not suggest the presence of residual population stratification. We confirmed the established association of rs1229984 with reduced alcohol consumption over the life-course, contributing new evidence of an effect before and during pregnancy.

Hepatitis B virus and sexual behavior in Rakai, Uganda.

HIV and hepatitis B virus (HBV) co-infection poses important public health considerations in resource-limited settings. Demographic data and sera from adult participants of the Rakai Health Sciences Program Cohort in Southwestern Uganda were examined to determine HBV seroprevalence patterns in this area of high HIV endemicity prior to the introduction of anti-retroviral therapy. Commercially available EIAs were used to detect prevalent HBV infection (positive for HBV core antibody [anti-HBc] and/or positive HBV surface antigen [HBsAg]), and chronic infection (positive for HBsAg). Of 438 participants, 181 (41%) had prevalent HBV infection while 21 (5%) were infected chronically. Fourteen percent of participants were infected with HIV. Fifty three percent showed evidence of prevalent HBV infection compared to 40% among participants infected with HIV (P = 0.067). Seven percent of participants infected with HIV were HBsAg positive compared to 4% among participants not infected with HIV (P = 0.403). The prevalence of prevalent HBV infection was 55% in adults aged >50 years old, and 11% in persons under 20 years. In multivariable analysis, older age, HIV status, and serologic syphilis were significantly associated with prevalent HBV infection. Transfusion status and receipt of injections were not significantly associated with HBV infection. Contrary to expectations that HBV exposure in Uganda occurred chiefly during childhood, prevalent HBV infection was found to increase with age and was associated sexually transmitted diseases (HIV and syphilis.) Therefore vaccination against HBV, particularly susceptible adults with HIV or at risk of HIV/STDs should be a priority.

Will circumcision provide even more protection from HIV to women and men? New estimates of the population impact of circumcision interventions.

BACKGROUND: Mathematical modelling has indicated that expansion of male circumcision services in high HIV prevalence settings can substantially reduce population-level HIV transmission. However, these projections need revision to incorporate new data on the effect of male circumcision on the risk of acquiring and transmitting HIV. METHODS: Recent data on the effect of male circumcision during wound healing and the risk of HIV transmission to women were synthesised based on four trials of circumcision among adults and new observational data of HIV transmission rates in stable partnerships from men circumcised at younger ages. New estimates were generated for the impact of circumcision interventions in two mathematical models, representing the HIV epidemics in Zimbabwe and Kisumu, Kenya. The models did not capture the interaction between circumcision, HIV and other sexually transmitted infections. RESULTS: An increase in the risk of HIV acquisition and transmission during wound healing is unlikely to have a major impact of circumcision interventions. However, it was estimated that circumcision confers a 46% reduction in the rate of male-to-female HIV transmission. If this reduction begins 2 years after the procedure, the impact of circumcision is substantially enhanced and accelerated compared with previous projections with no such effect-increasing by 40% the infections averted by the intervention overall and doubling the number of infections averted among women. CONCLUSIONS: Communities, and especially women, may benefit much more from circumcision interventions than had previously been predicted, and these results provide an even greater imperative to increase scale-up of safe male circumcision services.

Non-enrollment for free community HIV care: findings from a population-based study in Rakai, Uganda.

Improved understanding of HIV-related health-seeking behavior at a population level is important in informing the design of more effective HIV prevention and care strategies. We assessed the frequency and determinants of failure to seek free HIV care in Rakai, Uganda. HIV-positive participants in a community cohort who accepted VCT were referred for free HIV care (cotrimoxazole prophylaxis, CD4 monitoring, treatment of opportunistic infections, and, when indicated, antiretroviral therapy). We estimated proportion and adjusted Prevalence Risk Ratios (adj. PRR) of non-enrollment into care six months after receipt of VCT using log-binomial regression. About 1145 HIV-positive participants in the Rakai Community Cohort Study accepted VCT and were referred for care. However, 31.5% (361/1145) did not enroll into HIV care six months after referral. Non-enrollment was significantly higher among men (38%) compared to women (29%, p=0.005). Other factors associated with non-enrollment included: younger age (15-24 years, adj. PRR = 2.22; 95% CI: 1.64, 3.00), living alone (adj. PRR = 2.22; 95% CI: 1.57, 3.15); or in households with 1-2 co-residents (adj. PRR = 1.63; 95% CI: 1.31, 2.03) compared to three or more co-residents, or a CD4 count >250 cells/ul (adj. PRR = 1.81; 95% CI: 1.38, 2.46). Median (IQR) CD4 count was lower among enrolled 388 cells/ul (IQR: 211,589) compared to those not enrolled 509 cells/ul (IQR: 321,754). About one-third of HIV-positive persons failed to utilize community-based free services. Non-use of services was greatest among men, the young, persons with higher CD4 counts and the more socially isolated, suggesting a need for targeted strategies to enhance service uptake.

Family income and child cognitive and behavioural development in the United Kingdom: does money matter?

This study investigates the extent to which family income is associated with an extensive range of child cognitive and behavioural outcomes in a cohort of almost 19 000 British children born between 2000 and 2001. Merging the economists' and developmental psychologists' approaches, it also attempts to identify the main mechanisms through which family economic resources translate into better developmental outcomes for children. The relative and joint relevance of three groups of mediating factors (parental stress, parental investment and other family-related pathways), identified from the recent economic and psychological literature, are examined both in a cross-sectional ('mopping-up' approach) and in a panel data (fixed effects models) context. Results indicate a weak or absent direct effect of family economic resources on child development after controlling for potential mediating mechanisms. The study also identifies key mediating factors (e.g. maternal depression, a cognitively stimulating home environment, parenting practices and length of breastfeeding) that could be targeted by government initiatives in order to effectively improve children's intellectual development and behaviour beyond what income redistribution can achieve.

The effectiveness of antenatal care programmes to reduce infant mortality and preterm birth in socially disadvantaged and vulnerable women in high-income countries: a systematic review.

BACKGROUND: Infant mortality has shown a steady decline in recent years but a marked socioeconomic gradient persists. Antenatal care is generally thought to be an effective method of improving pregnancy outcomes, but the effectiveness of specific antenatal care programmes as a means of reducing infant mortality in socioeconomically disadvantaged and vulnerable groups of women has not been rigorously evaluated. METHODS: We conducted a systematic review, focusing on evidence from high income countries, to evaluate the effectiveness of alternative models of organising or delivering antenatal care to disadvantaged and vulnerable groups of women vs. standard antenatal care. We searched Medline, Embase, Cinahl, PsychINFO, HMIC, CENTRAL, DARE, MIDIRS and a number of online resources to identify relevant randomised and observational studies. We assessed effects on infant mortality and its major medical causes (preterm birth, congenital anomalies and sudden infant death syndrome (SIDS)) RESULTS: We identified 36 distinct eligible studies covering a wide range of interventions, including group antenatal care, clinic-based augmented care, teenage clinics, prenatal substance abuse programmes, home visiting programmes, maternal care coordination and nutritional programmes. Fifteen studies had adequate internal validity: of these, only one was considered to demonstrate a beneficial effect on an outcome of interest. Six interventions were considered 'promising'. CONCLUSIONS: There was insufficient evidence of adequate quality to recommend routine implementation of any of the programmes as a means of reducing infant mortality in disadvantaged/vulnerable women. Several interventions merit further more rigorous evaluation.

A Factorial Survey Investigating the Effect of Disclosing Parental Intellectual Disability on Risk Assessments by Children's Social Workers in Child Safeguarding Scenarios.

Literature suggests that, as parents, people with intellectual disabilities experience disproportionately high rates of child removal compared to other groups. A factorial survey of 191 children's social workers investigated the effect of disclosing parental intellectual disability (ID) upon risk assessments in a range of hypothetical child safeguarding scenarios. The case scenarios depicted a range of child safeguarding situations and parents' ID status was randomly included as an additional item of information. The data were fitted into a generalised ordinal logistic regression model. Findings indicate that when presented with scenarios considered to be less risky, the parental ID disclosure contributed significantly to a higher risk assessment score. However, when presented with scenarios that were considered more risky, the additional parental ID disclosure did not significantly contribute to a higher score. These findings indicate that the risk associated with parental ID is not fixed but relative to the situation in which it is encountered. The research concludes that in cases of low risk, the effect of parental ID is identified as a support need, whereas the lesser contribution of the disclosure to assessments of higher risk cases may indicate that parental ID is overlooked.
