Physician personal breastfeeding experience and clinical care of the breastfeeding dyad.

BACKGROUND: Prior research suggests that physicians' personal experience with breastfeeding may influence their attitudes toward breastfeeding. This phenomenon has not been explored in well-newborn care physician leaders, whose administrative responsibilities often include drafting and approval of hospital breastfeeding and formula supplementation policies. METHODS: We conducted a mixed-methods study, surveying physicians in the Better Outcomes through Research for Newborns (BORN) network. We examined physician attitudes toward recommending breastfeeding and their breastfeeding experience. Qualitative analysis was conducted on responses to the question: "How do you think your breastfeeding experience influences your clinical practice?" RESULTS: Of 71 participants, most (92%) had a very positive attitude toward breastfeeding with 75% of respondents reporting personal experience with breastfeeding. Of these, 68% had a very positive experience, 25% had a somewhat positive experience, and 6% had a neutral experience. Four themes emerged with respect to the effect of breastfeeding experience on practice: (1) empathy with breastfeeding struggles, (2) increased knowledge and skills, (3) passion for breastfeeding benefits, and (4) application of personal experience in lieu of evidence-based medicine, particularly among those who struggled with breastfeeding. CONCLUSIONS: Well-newborn care physician leaders reported positive attitudes about breastfeeding, increased support toward breastfeeding persons, and a perception of improved clinical lactation skills. Those who struggled with breastfeeding reported increased comfort with recommending formula supplementation to their own patients. Medical education about evidence-based breastfeeding support practices and provision of lactation support to physicians has the potential to affect public health through improved care for the patients they serve.

Supplementation Practices and Donor Milk Use in US Well-Newborn Nurseries.

BACKGROUND AND OBJECTIVES: Guidelines encourage exclusive breastfeeding for healthy newborns but lack specificity regarding criteria for medically indicated supplementation, including type, timing, and best practices. We set out to describe practice patterns and provider perspectives regarding medically indicated supplementation of breastfeeding newborns across the United States. METHODS: From 2017 to 2018, we surveyed the Better Outcomes through Research for Newborns representative from each Better Outcomes through Research for Newborns hospital regarding practices related to medically indicated supplementation. We used descriptive statistics to compare practices between subgroups defined by breastfeeding prevalence and used qualitative methods and an inductive approach to describe provider opinions. RESULTS: Of 96 providers representing discrete hospitals eligible for the study, 71 participated (74% response rate). Practices related to criteria for supplementation and pumping and to type and caloric density of supplements varied widely between hospitals, especially for late preterm infants, whereas practices related to lactation consultant availability and hand expression education were more consistent. The most commonly reported criterion for initiating supplementation was weight loss of ≥10% from birth weight, and bottle-feeding was the most commonly reported method; however, practices varied widely. Donor milk use was reported at 20 (44%) hospitals with ≥81% breastfeeding initiation and 1 (4%) hospital with <80% breastfeeding initiation (P = .001). CONCLUSIONS: Strategies related to supplementation vary among US hospitals. Donor milk availability is concentrated in hospitals with the highest prevalence of breastfeeding. Implementation of evidence-based management of supplementation among US hospitals has the potential to improve the care of term and late preterm newborns.

Pacifier Use and Breastfeeding: A Qualitative Study of Postpartum Mothers.

Objective: Due to the inconclusive evidence supporting the traditional recommendation to avoid early pacifier use among breastfeeding newborns, this study aims to understand what information mothers are receiving from hospital based care providers and their perspectives about pacifier use in the newborn period. Methods: Interviews with mothers of healthy, term newborns during the postpartum hospitalization were conducted in this qualitative study. Results: Qualitative data analysis yielded several major themes that included the following: (1) pacifiers are beneficial for the maternal/infant experience, (2) concerns that pacifiers may interfere with breastfeeding, and (3) concerns about long-term use (including reliance and effect on teeth). Conclusion: Given the maternal perception of benefit and the paucity of high-quality evidence showing harm, further research on the effects of early pacifier use is needed.

Exposure to Hospital Breastfeeding Support by Maternal Race and Ethnicity: A Pilot Study.

INTRODUCTION: The Ten Steps to Successful Breastfeeding are evidence-based practices used to improve breastfeeding outcomes, and most are to be implemented shortly after birth. Although breastfeeding is increasing in the United States, racial disparities persist. Available national samples used to examine trends in maternity care rely on maternal recall, which may be subject to error and bias. Thus, we conducted a pilot study to determine the feasibility of a large-scale study conducted during the birth hospitalization to explore patterns in practices supporting breastfeeding across maternal racial and ethnic groups. METHODS: A convenience sample of 37 women with healthy, term singletons who intended to breastfeed were recruited from 2 academic medical centers (one in the Midwest and the other in the Pacific Northeast) and surveyed during their birth hospitalizations between July and November 2016. Women were asked whether they received the 7 steps that are recommended to be implemented shortly after birth (eg, encourage breastfeeding on demand). We generated descriptive statistics and conducted independent chi-square tests to determine associations between self-reported exposure to these 7 practices and race and ethnicity. RESULTS: In this sample, 23 women (62.2%) were non-Hispanic white, 5 (13.5%) were non-Hispanic black, and 6 (16.2%) were Hispanic. Approximately 26 (70.3%) reported experiencing at least 6 of the 7 practices. Non-Hispanic white women were significantly more likely to room-in with their newborns, were less likely to receive formula, and were less likely to receive pacifiers than women of other races and ethnicities (P < .05). Furthermore, differences in exposure to practices by maternal race/ethnicity appeared more pronounced at one center than the other. DISCUSSION: Preliminary findings suggest that some practices used to improve breastfeeding may be provided inconsistently across maternal racial and ethnic groups. Additional investigation is needed to further explore these patterns and to identify reasons for any inconsistencies in order to reduce health disparities in the United States.

Hospital breastfeeding support and exclusive breastfeeding by maternal prepregnancy body mass index.

Overweight and obese mothers in the United States have disproportionately lower rates of exclusive breastfeeding than mothers of normal weight. The Ten Steps to Successful Breastfeeding (Ten Steps), a series of evidence-based practices designed to support breastfeeding initiation, duration, and exclusivity, demonstrate effectiveness at the population level. It is unknown, however, whether they are consistently provided to women across all maternal body mass index (BMI) categories. We sought to determine whether pre-pregnancy BMI is associated with the implementation and effectiveness of the Ten Steps. We used data from Listening to Mothers III, a cross-sectional survey administered to a sample of mothers who delivered in U.S. hospitals between July 2011 and June 2012. Measures of the Ten Steps were based on maternal self-report on Listening to Mothers III. Our analytic sample was limited to mothers of term infants intending to breastfeed (N = 1,506, weighted). We conducted chi-square testing and constructed weighted multivariable logistic regression models to account for potential confounders. Results suggest that two practices (i.e., holding their babies skin-to-skin for the first time and being encouraged to breastfeed on demand) were more strongly associated with exclusive breastfeeding among mothers with obesity than other mothers. Additionally, mothers with obesity reported holding babies skin-to-skin significantly less often than other mothers. Thus, interventions aimed at helping mothers with obesity to hold their babies skin-to-skin in the first hour and teaching them to breastfeed on demand have the potential to decrease the breastfeeding disparities in this population.

Exploring the Link between Maternity Leave and Postpartum Depression.

OBJECTIVES: Postpartum depression affects a substantial proportion of new mothers in the United States. Although most employed women return to paid work after birth, the association between duration of maternity leave and postpartum depression is unclear. We therefore aimed to explore this relationship among mothers in the United States. METHODS: Data included 177 mothers from a national survey who had returned to work full time after having a baby. Multivariable logistic regression was used to explore the independent association between duration of maternity leave and experiencing of postpartum depressive symptoms in the 2 weeks preceding the postpartum survey completion. RESULTS: Overall, duration of maternity leave was not significantly associated with experiencing postpartum depression symptoms (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.80-1.01). This effect, however, varied by duration of maternity leave. Among women who took maternity leaves of 12 weeks or less, every additional week of leave was associated with a lesser odds of experiencing postpartum depressive symptoms (OR, 0.58; 95% CI, 0.40-0.84). Among women who took maternity leaves longer than 12 weeks, leave duration was not associated with postpartum depression symptoms (OR, 0.97; 95% CI, 0.73-1.29). CONCLUSIONS: Maternity leaves equaling 12 weeks or less may contribute additional risk for postpartum depressive symptoms, possibly because mothers are juggling employment alongside of important physical and emotional changes during this period. This association underscores the importance of ensuring that mothers have at least 12 weeks of leave from full-time employment after the birth of a baby.

Human Donor Milk or Formula: A Qualitative Study of Maternal Perspectives on Supplementation.

BACKGROUND: Breastfeeding is fundamental to maternal and child health and is the most cost-effective intervention to reduce child mortality. Pasteurized human donor milk (HDM) is increasingly provided for term newborns requiring temporary supplementation. Few studies examine maternal perspectives on supplementation of term newborns. MATERIALS AND METHODS: We conducted semistructured in-person interviews with mothers of term newborns (n = 24) during postpartum hospitalization. Mothers were asked whether they had chosen or would choose to supplement with HDM versus infant formula, if medically indicated, and why. Data were gathered to saturation and analyzed inductively by consensus. Emerging semantic themes were compared between mothers who chose or would choose HDM and those who chose or would choose infant formula. RESULTS: Most mothers had concerns about HDM, including uncertainty regarding screening and substances passed through HDM. Experiences with prior children influenced decision-making. Mothers who chose or would choose HDM (56%, n = 14) praised it as "natural," and some felt suspicious of infant formula as "synthetic." Mothers who chose or would choose infant formula (44%, n = 10) did not know enough about HDM to choose it, and many viewed infant formula as a short-term solution to supply concerns. Mothers unanimously mistrusted online milk purchasing sources, although the majority felt positively about using a friend or family member's milk. CONCLUSIONS: Counseling regarding term newborn supplementation should focus on HDM education, specifically on areas of greatest concern and uncertainty such as donor selection, screening, transmission of substances, and mother's milk supply. Research is needed to assess the long-term impact of attitudes and choices on breastfeeding.

Effect of breastfeeding on postpartum depressive symptoms among adolescent and young adult mothers.

PURPOSE: To describe the association between breastfeeding and postpartum depressive symptoms among a sample of adolescent and young adult mothers and to determine whether breastfeeding difficulty moderates this association. MATERIALS AND METHODS: Data were derived from a prospective cohort of pregnant adolescent and young adult females (ages 14-21) as they transitioned to parenthood. This analysis uses data collected during pregnancy and at 6 months postpartum among mothers (n = 137) who initiated breastfeeding. Multivariable linear regression was used to adjust for prenatal depressive symptoms and other potential confounders. RESULTS: Postpartum depressive symptoms were not significantly associated with breastfeeding duration or breastfeeding at 6 months. Early breastfeeding difficulty moderated the association between depressive symptoms and breastfeeding at 6 months. Among young mothers who were still breastfeeding at 6 months, those who reported no early breastfeeding difficulties had the lowest depressive scores and those who reported much early breastfeeding difficulty had the highest depressive scores at 6 months. CONCLUSIONS: Minimizing challenges with breastfeeding may help improve postpartum mental health among adolescent and young adult mothers. Health care providers should help young pregnant women manage expectations about breastfeeding and ensure that they are linked to appropriate professional breastfeeding support during the early postpartum period.

Spending on social and public health services and its association with homicide in the USA: an ecological study.

OBJECTIVE: To examine whether state-level spending on social and public health services is associated with lower rates of homicide in the USA. DESIGN: Ecological study. SETTING: USA. PARTICIPANTS: All states in the USA and the District of Columbia for which data were available (n=42). PRIMARY OUTCOME MEASURE: Homicide rates for each state were abstracted from the US Department of Justice Federal Bureau of Investigation's Uniform Crime Reporting. RESULTS: After adjusting for potential confounding variables, we found that every $10 000 increase in spending per person living in poverty was associated with 0.87 fewer homicides per 100 000 population or approximately a 16% decrease in the average homicide rate (estimate=-0.87, SE=0.15, p<0.001). Furthermore, there was no significant effect in the quartile of states with the highest percentages of individuals living in poverty but significant effects in the quartiles of states with lower percentages of individuals living in poverty. CONCLUSIONS: Based on our findings, spending on social and public health services is associated with significantly lower homicide rates at the state level. Although we cannot infer causality from this research, such spending may provide promising avenues for homicide reduction in the USA, particularly among states with lower levels of poverty.

Pacifiers and Exclusive Breastfeeding: Does Risk for Postpartum Depression Modify the Association?

BACKGROUND: Postpartum depression is associated with lower rates of breastfeeding. Evidence describing the effect of pacifiers on breastfeeding is inconsistent, and previous research suggests that pacifiers may help vulnerable mothers breastfeed. Research aim: This study aimed to determine (a) how receiving a pacifier in the hospital affects exclusive breastfeeding (EBF) at 1 week and 3 months postpartum and (b) whether this association is modified by risk for postpartum depression (PPD). METHODS: Data were derived from Listening to Mothers III. We included participants ( n = 1,349) who intended to breastfeed and delivered at term. Mothers were considered at high risk for PPD if they reported feeling the need to receive treatment for depression during pregnancy. We used weighted multivariable logistic regression models to adjust for covariates. RESULTS: Receiving a pacifier in the hospital was not significantly associated with EBF at 1 week (odds ratio [ OR] = 0.84, 95% confidence interval [CI] [0.62, 1.12]) but was significantly associated with lower odds of EBF at 3 months postpartum ( OR = 0.72, 95% CI [0.54, 0.95]). Risk for PPD modified this association. Among mothers at high risk for PPD, receiving a pacifier was significantly associated with increased odds of EBF ( OR = 3.31, 95% CI [1.23, 8.97] at 1 week and OR = 5.27, 95% CI [1.97, 14.12] at 3 months); however, among mothers who were at lower risk for PPD, receiving a pacifier was associated with decreased odds of EBF ( OR = 0.75, 95% CI [0.56, 1.02] at 1 week and OR = 0.62, 95% CI [0.46, 0.82] at 3 months). CONCLUSION: Pacifiers may help protect against early cessation of EBF among mothers at high risk for depression. Additional research is needed to better understand this association.

Impact of social service and public health spending on teenage birth rates across the USA: an ecological study.

OBJECTIVE: To examine whether greater state-level spending on social and public health services such as income, education and public safety is associated with lower rates of teenage births in USA. DESIGN: Ecological study. SETTING: USA. PARTICIPANTS: 50 states. PRIMARY OUTCOME MEASURE: Our primary outcome measure was teenage birth rates. For analyses, we constructed marginal models using repeated measures to test the effect of social spending on teenage birth rates, accounting for several potential confounders. RESULTS: The unadjusted and adjusted models across all years demonstrated significant effects of spending and suggested that higher spending rates were associated with lower rates of teenage birth, with effects slightly diminishing with each increase in spending (linear effect: B=-0.20; 95% CI -0.31 to 0.08; p<0.001 and quadratic effect: B=0.003; 95% CI 0.002 to 0.005; p<0.001). CONCLUSION: Higher state spending on social and public health services is associated with lower rates of teenage births. As states seek ways to limit healthcare costs associated with teenage birth rates, our findings suggest that protecting existing social service investments will be critical.

Hospital practices to promote breastfeeding: The effect of maternal age.

BACKGROUND: Breastfeeding rates are disproportionately low among young mothers in the United States. Although the use of hospital practices to promote breastfeeding is widely supported, the extent to which these practices help explain breastfeeding disparities by maternal age is unclear. Accordingly, we aimed to explore how maternal age may affect (1) receipt of hospital practices and (2) associations between these practices and exclusive breastfeeding. METHODS: Data were derived from participants (n = 1598) of Listening to Mothers III, a national survey administered to mothers of singleton births in United States hospitals from July 2011 to June 2012. We used multivariable logistic regression models and interaction terms to examine maternal age as an effect modifier. RESULTS: Compared with mothers aged 30 and older, mothers aged 18-19 had lower odds of reporting that nurses helped them initiate breastfeeding when ready (OR 0.59 [95% CI 0.35-0.99]), they roomed-in with their baby (OR 0.32 [95% CI 0.19-54]) and they did not receive a pacifier (OR 0.53 [95% CI 0.32-0.90]). Many associations with breastfeeding were stronger among mothers aged 18-19 and 20-24 than mothers aged 25-29 and 30 and older. Additionally, compared with receiving a pacifier, not receiving a pacifier was associated with greater odds of exclusive breastfeeding at 1 week among mothers aged 30 and older (OR 1.47 [95% CI 1.02-2.11]) but lower odds among mothers aged 18-19 (OR 0.26 [95% CI 0.10-0.70]). CONCLUSIONS: Hospital practices to promote breastfeeding may be differentially implemented by maternal age. Encouraging teenage mothers to room-in with their babies may be particularly important for reducing breastfeeding disparities. Pacifier use among babies of teenage mothers requires further exploration.

Exploring Trajectories and Predictors of Depressive Symptoms Among Young Couples During Their Transition to Parenthood.

Objectives Young parents may be particularly vulnerable to poor mental health during the postpartum period. Little research exists, however, to adequately describe trajectories of depressive symptoms during their transition to parenthood, particularly among young fathers. Therefore, we aim to explore trajectories of depressive symptoms from pregnancy through 1 year postpartum among young expectant mothers and their partners. Methods Data are derived from a longitudinal cohort of pregnant adolescent females (ages 14-21; n = 220) and their male partners (n = 190). Multilevel regression models examined the impact of time on depressive symptoms, and generalized linear regression models examined predictors of experiencing elevated depressive symptoms. Results Depressive symptoms significantly decreased from pregnancy through 1 year postpartum among young females. Overall, depressive symptoms did not significantly change over time among young males. Predictors of elevated depressive symptoms common across genders included social support and relationship satisfaction. Marijuana use resulted in almost twice the odds of experiencing elevated depressive symptoms among young fathers (OR 1.82; 95 % CI 1.04, 3.20). Conclusion for Practice Providing strategies for strengthening social support networks among young parents may be an effective way to improve mental health among young parents, particularly during this period of potential social isolation. Additionally, providing tools to strengthen relationships between partners may also be effective for both young mothers and fathers. Substance use may be a marker for depressive symptoms among young fathers and thus screening for substance use could be important to improving their mental health. Future research is needed to better understand how IPV affects mental health, particularly among young fathers.

Hepatitis C and HIV incidence and harm reduction program use in a conflict setting: an observational cohort of injecting drug users in Kabul, Afghanistan.

BACKGROUND: Armed conflict may increase the risk of HIV and other pathogens among injecting drug users (IDUs); however, there are few prospective studies. This study aimed to measure incidence and potential predictors, including environmental events and needle and syringe distribution and collection program (NSP) use, of hepatitis C virus (HCV) and HIV among IDUs in Kabul, Afghanistan. METHODS: Consenting adult IDUs completed interviews quarterly in year 1 and semi-annually in year 2 and HCV and HIV antibody testing semi-annually through the cohort period (November 2007-December 2009). Interviews detailed injecting and sexual risk behaviors, NSP service use, and conflict-associated displacement. Quarters with peak conflict or local displacement were identified based on literature review, and key events, including insurgent attacks and deaths, were reported with simple counts. Incidence and predictors of HCV and HIV were measured with Cox proportional hazards models. RESULTS: Of 483 IDUs enrolled, 385 completed one or more follow-up visits (483.8 person-years (p-y)). All participants were male with a median age of 28 years and a median duration of injecting of 2 years. Reported NSP use among the participants ranged from 59.9 to 70.5 % in the first year and was 48.4 and 55.4 % at 18 and 24 months, respectively. There were 41 confirmed deaths, with a crude death rate of 93.4/1000 p-y (95 % confidence interval (CI) 67.9-125) and overdose as the most common cause. HCV and HIV incidence were 35.6/100 p-y (95 % CI 28.3-44.6) and 1.5/100 p-y (95 % CI 0.6-3.3), respectively. Changing from injecting to smoking was protective for HCV acquisition (adjusted hazard ratio (AHR) = 0.53, 95 % CI 0.31-0.92), while duration of injecting (AHR = 1.09, 95 % CI 1.01-1.18/year) and sharing syringes (AHR = 10.09, 95 % CI 1.01-100.3) independently predicted HIV infection. CONCLUSION: There is high HCV incidence and high numbers of reported deaths among male Kabul IDUs despite relatively consistent levels of harm reduction program use; peak violence periods did not independently predict HCV and HIV risk. Programming should increase awareness of HCV transmission and overdose risks, prepare clients for harm reduction needs during conflict or other causes of displacement, and continue efforts to engage community and police force support.

Violence against Congolese refugee women in Rwanda and mental health: a cross-sectional study using latent class analysis.

OBJECTIVE: To examine patterns of conflict-related violence and intimate partner violence (IPV) and their associations with emotional distress among Congolese refugee women living in Rwanda. DESIGN: Cross-sectional study. SETTING: Two Congolese refugee camps in Rwanda. PARTICIPANTS: 548 ever-married Congolese refugee women of reproductive age (15-49 years) residing in Rwanda. PRIMARY OUTCOME MEASURE: Our primary outcome was emotional distress as measured using the Self-Report Questionnaire-20 (SRQ-20). For analysis, we considered participants with scores greater than 10 to be experiencing emotional distress and participants with scores of 10 or less not to be experiencing emotional distress. RESULTS: Almost half of women (49%) reported experiencing physical, emotional or sexual violence during the conflict, and less than 10% of women reported experiencing of any type of violence after fleeing the conflict. Lifetime IPV was reported by approximately 22% of women. Latent class analysis derived four distinct classes of violence experiences, including the Low All Violence class, the High Violence During Conflict class, the High IPV class and the High Violence During and After Conflict class. In multivariate regression models, latent class was strongly associated with emotional distress. Compared with women in the Low All Violence class, women in the High Violence During and After Conflict class and women in the High Violence During Conflict had 2.7 times (95% CI 1.11 to 6.74) and 2.3 times (95% CI 1.30 to 4.07) the odds of experiencing emotional distress in the past 4 weeks, respectively. Furthermore, women in the High IPV class had a 4.7 times (95% CI 2.53 to 8.59) greater odds of experiencing emotional distress compared with women in the Low All Violence class. CONCLUSIONS: Experiences of IPV do not consistently correlate with experiences of conflict-related violence, and women who experience high levels of IPV may have the greatest likelihood for poor mental health in conflict-affected settings.

HPV vaccine acceptance among adolescent males and their parents in two suburban pediatric practices.

PURPOSE: To measure HPV vaccine acceptance among unvaccinated adolescent males and parents and correlate acceptance with knowledge, awareness, and personal experience. METHODS: Adolescent males ages 11-21 years old and their parents completed questionnaires measuring attitudes and knowledge about HPV vaccination and personal experience. Acceptance was defined as wanting the vaccine and conditional acceptance as wanting the vaccine if it would protect against genital warts or cervical cancer. RESULTS: Adolescent (n=154) and parent (n=121) vaccine acceptance was low (16% and 34%, respectively); however, conditional acceptance was higher. While adolescents had similar conditional acceptance for a vaccine against genital warts and cervical cancer, parents reported higher conditional acceptance for protection against genital warts. Independent predictors of acceptance included personal experience and demographic variables. CONCLUSIONS: HPV vaccine acceptance among adolescents and parents was low. Conditional acceptance levels highlight the importance of education about a few important benefits of HPV vaccination, which may increase vaccination rates.

Breastfeeding among adolescent mothers: a systematic review of interventions from high-income countries.

Despite growing evidence of the benefits of breastfeeding, rates of breastfeeding remain disproportionately low among adolescent mothers compared with older mothers in the United States. Current interventions primarily target adult women, and little evidence is available for breastfeeding promotion among young women. Accordingly, we aim to review interventions designed to improve breastfeeding rates among adolescents to make recommendations for future research and practice. We searched MEDLINE and PsycINFO for articles that evaluated interventions aiming to improve rates of breastfeeding initiation, duration, or exclusivity among adolescents. Inclusion criteria included interventions targeting pregnant or postpartum adolescents (mean/median age <22 years) that were conducted in high-income settings. Six interventions met our inclusion criteria; of these, 4 interventions aimed to increase breastfeeding initiation, 5 aimed to increase breastfeeding duration, and 4 aimed to increase breastfeeding exclusivity. Interventions included school-based programs, home visits, and telephone support that were implemented by a combination of peer counselors, nurse clinicians, doulas, and lactation consultants. Only 1 intervention, a combination of education and counseling provided by a lactation consultant-peer counselor team, significantly improved both breastfeeding initiation and duration. Other results were mixed, and studies were subject to several methodological limitations. We recommend that more interventions should be developed and evaluated. In addition, interventions should be less resource intensive, be more theoretically driven, and specifically include mothers and partners of adolescents to successfully promote breastfeeding among adolescent mothers.

The impact of future expectations on adolescent sexual risk behavior.

Rates of STIs, HIV, and pregnancy remain high among adolescents in the US, and recent approaches to reducing sexual risk have shown limited success. Future expectations, or the extent to which one expects an event to actually occur, may influence sexual risk behavior. This prospective study uses longitudinal data from the National Longitudinal Survey of Youth 1997 (n = 3,205 adolescents; 49.8% female) to examine the impact of previously derived latent classes of future expectations on sexual risk behavior. Cox regression and latent growth models were used to determine the effect of future expectations on age at first biological child, number of sexual partners, and inconsistent contraception use. The results indicate that classes of future expectations were uniquely associated with each outcome. The latent class reporting expectations of drinking and being arrested was consistently associated with the greatest risks of engaging in sexual risk behavior compared with the referent class, which reported expectations of attending school and little engagement in delinquent behaviors. The class reporting expectations of attending school and drinking was associated with having greater numbers of sexual partners and inconsistent contraception use but not with age at first biological child. The third class, defined by expectations of victimization, was not associated with any outcome in adjusted models, despite being associated with being younger at the birth of their first child in the unadjusted analysis. Gender moderated specific associations between latent classes and sexual risk outcomes. Future expectations, conceptualized as a multidimensional construct, may have a unique ability to explain sexual risk behaviors over time. Future strategies should target multiple expectations and use multiple levels of influence to improve individual future expectations prior to high school and throughout the adolescent period.

Correlates of complete childhood vaccination in East African countries.

BACKGROUND: Despite the benefits of childhood vaccinations, vaccination rates in low-income countries (LICs) vary widely. Increasing coverage of vaccines to 90% in the poorest countries over the next 10 years has been estimated to prevent 426 million cases of illness and avert nearly 6.4 million childhood deaths worldwide. Consequently, we sought to provide a comprehensive examination of contemporary vaccination patterns in East Africa and to identify common and country-specific barriers to complete childhood vaccination. METHODS: Using data from the Demographic and Health Surveys (DHS) for Burundi, Ethiopia, Kenya, Rwanda, Tanzania, and Uganda, we looked at the prevalence of complete vaccination for polio, measles, Bacillus Calmette-Guérin (BCG) and DTwPHibHep (DTP) as recommended by the WHO among children ages 12 to 23 months. We conducted multivariable logistic regression within each country to estimate associations between complete vaccination status and health care access and sociodemographic variables using backwards stepwise regression. RESULTS: Vaccination varied significantly by country. In all countries, the majority of children received at least one dose of a WHO recommended vaccine; however, in Ethiopia, Tanzania, and Uganda less than 50% of children received a complete schedule of recommended vaccines. Being delivered in a public or private institution compared with being delivered at home was associated with increased odds of complete vaccination status. Sociodemographic covariates were not consistently associated with complete vaccination status across countries. CONCLUSIONS: Although no consistent set of predictors accounted for complete vaccination status, we observed differences based on region and the location of delivery. These differences point to the need to examine the historical, political, and economic context of each country in order to maximize vaccination coverage. Vaccination against these childhood diseases is a critical step towards reaching the Millennium Development Goal of reducing under-five mortality by two-thirds by 2015 and thus should be a global priority.
