Associations Between Preconception Counseling and Maternal Behaviors Before and During Pregnancy

Preconception counseling (PCC) is a vital component of preconception care. Through counseling, providers educate and recommend strategies to improve health and birth outcomes for women of reproductive age. The objective of our analysis was to assess the associations between receipt of PCC and positive maternal behaviors before and during pregnancy. We analyzed 2004?C2008 Pregnancy Risk Assessment Monitoring System data from Maine, New Jersey, Utah, and Vermont. Multivariable logistic regression was used to investigate the associations between receipt of PCC and prepregnancy daily multivitamin consumption, first-trimester entry into prenatal care, and cessation of smoking and drinking before pregnancy among women who smoked/drank in the 2?years preceding the survey, adjusting for a wide range of maternal characteristics. Overall, 32% of women reported receipt of PCC, with particularly low rates reported among women with an unintended pregnancy (14%) and no health insurance prior to pregnancy (14%). Receipt of PCC was associated with daily prepregnancy multivitamin consumption (adjusted odds ratio [AOR]?=?4.4; 95% confidence interval [CI]?=?4.0, 4.7), first-trimester entry into prenatal care for women with an intended pregnancy (AOR?=?2.1; 95% CI?=?1.8, 2.4), and drinking cessation before pregnancy among women who drank in the 2?years preceding the survey (AOR?=?1.3; 95% CI?=?1.2, 1.5). PCC was associated with positive maternal behaviors that increase the likelihood of a healthy woman, pregnancy, and infant. Unfortunately, less than one-third of women with a recent live birth reported receiving PCC. These data provide population-based evidence suggesting the value of PCC in the promotion of healthy maternal behaviors for women with intended or unintended pregnancies.     

Respiratory Illness Hospitalizations Among Pregnant Women During Influenza Season, 1998–2008

To examine health care burden, pregnancy outcomes and impact of high risk medical conditions among pregnancy hospitalizations during influenza season. Length of stay, hospitalization charges, and delivery complications were compared between hospitalizations with and without respiratory illness and compared by presence of high risk medical conditions. Length of stay and hospital charges were significantly increased among respiratory illness hospitalizations versus non-respiratory hospitalizations. Among respiratory illness hospitalization, the odds of intrauterine fetal demise were increased (adjusted odds ratio (aOR) 2.50, 95 % confidence interval (CI) 1.97–3.18). Among live births, there were higher odds of preterm delivery (aOR 3.82, 95 % CI 3.53–4.14), cesarean delivery (aOR 3.47, 95 % CI 3.22–3.74), and fetal distress (aOR 2.33, 95 % CI 2.15–2.52). The presence of high risk medical conditions did not impact pregnancy outcomes. Among pregnant women hospitalized during influenza season, those with respiratory illness were more likely than those without respiratory illness to have poor perinatal outcomes, regardless of the presence of high risk conditions. Efforts to minimize influenza morbidity, including universal vaccination and early antiviral therapy should be promoted among all pregnant women.     

Risk of Spontaneous Preterm Birth in Relation to Maternal Exposure to Intimate Partner Violence During Pregnancy in Peru

Intimate partner violence (IPV) is increasingly recognized as an important cause of maternal and perinatal morbidity. We assessed the relation between IPV and risk of spontaneous preterm birth (PTB) among Peruvian women. The study was conducted among 479 pregnant women who delivered a preterm singleton infant (<37 weeks gestation) and 480 controls (≥37 weeks gestation). Participants’ exposure to physical and emotional violence during pregnancy was collected during in-person interviews conducted after delivery and while patients were in hospital. Odds ratios (aOR) and 95 % confidence intervals (CI) were estimated from logistic regression models. The prevalence of any IPV during pregnancy was 52.2 % among cases and 34.6 % among controls. Compared with those reporting no exposure to IPV during pregnancy, women reporting any exposure had a 2.1-fold increased risk of PTB (95 % CI 1.59–2.68). The association was attenuated slightly after adjusting for maternal age, pre-pregnancy weight, and other covariates (OR = 1.99; 95 % CI 1.52–2.61). Emotional abuse in the absence of physical violence was associated with a 1.6-fold (95 % CI 1.21–2.15) increased risk of PTB. Emotional and physical abuse during pregnancy was associated with a 4.7-fold increased risk of PTB (95 % CI 2.74–7.92). Associations of similar directions and magnitudes were observed when PTB were sub-categorized according to clinical presentation or severity. IPV among pregnant women is common and is associated with an increased risk of PTB. Our findings and those of others support recent calls for coordinated global health efforts to prevent violence against women.     

Prospective Association of Intimate Partner Violence with Receipt of Clinical Preventive Services in Women of Reproductive Age

BackgroundWomen who experience intimate partner violence (IPV) have a greater risk for adverse health outcomes, suggesting the importance of preventive services in this group. Little prior research has explored how IPV exposure impacts receipt of relevant preventive services. We assess the prospective association of IPV exposure with receiving specific preventive services.MethodsWomen in the Central Pennsylvania Women's Health Study's longitudinal cohort study (conducted 2004–2007; n = 1,420) identified past-year exposure to IPV at baseline and receipt of IPV-relevant preventive services (counseling for safety and violence concerns, tests for sexually transmitted infections [STIs], counseling for STIs, Pap testing, counseling for smoking/tobacco use, alcohol/drug use, and birth control) at 2-year follow-up. Multiple logistic regression analysis assessed the impact of IPV on service receipt, controlling for relevant covariates.FindingsWomen exposed to IPV had greater odds of receiving safety and violence counseling (adjusted odds ratio [AOR], 2.40; 95% confidence interval [CI], 1.25–4.61), and tests for STIs (AOR, 2.46; 95% CI, 1.41–4.28) compared with women who had not been exposed to IPV. Independent of other predictors, including IPV, women who saw an obstetrician-gynecologist were more likely to receive Pap tests, STI/HIV testing and counseling, and birth control counseling, compared with women who had not seen an obstetrician-gynecologist.ConclusionOverall rates of preventive service receipt for all women in the sample were low. Women exposed to IPV were more likely to receive safety and violence counseling and STI testing, and seeing an obstetrician-gynecologist increased the odds of receiving several preventive services.     

Maternal Sociodemographic Characteristics,Experiences and Health Behaviors Associated with Postpartum Care Utilization: Evidence from Maryland PRAMS Dataset, 2012–2013

Objectives Postpartum visits are increasingly recognized as a window of opportunity for health care providers to counsel new mothers and promote healthy behaviors, including increasing contraceptive use and screening for postpartum depression. In Maryland, there is a lack of research on postpartum visit (PPV) attendance and the specific risk factors associated with not receiving postpartum care. In this study, we estimated the proportion of mothers in Maryland who attended a PPV and assessed maternal sociodemographic characteristics and health behaviors associated with PPV non-attendance. Methods Data were analyzed from the 2012 and 2013 Maryland Pregnancy Risk Assessment Monitoring System (n?=?2204). Bivariate and multivariable logistic regression were performed to examine the association between covariates and PPV non-attendance. Results Overall, 89.6% of women reported PPV attendance. Bivariate analyses between maternal sociodemographic and health behavior characteristics and PPV non-attendance indicated that being unmarried (OR 3.03, 95% CI 2.12–4.31), experiencing infant loss (OR 7.17, 95% CI 2.57–19.97), working during pregnancy (OR 0.44, 95% CI 0.31–0.63) and not receiving dental care (OR 2.03, 95% CI 1.43–2.88) as significant risk factors for PPV non-attendance. After controlling for known and theoretical confounders, experiencing an infant loss (aOR 5.18, 95% CI 1.54–17.4), not receiving dental care (aOR 1.54, 95% CI 1.06–2.26) and working during pregnancy (aOR 0.61, 95% CI 0.41–0.93) emerged as strong predictors of PPV non-attendance. Conclusions for Practice Mothers who recently experienced an infant death were at greatest risk for not attending a PPV, suggesting the need to establish comprehensive support networks, including grief counseling and additional service reminders for mothers who experienced an infant death.     

Ethnicity and Self-Perceived Oral Health in Colombia: A Cross-Sectional Analysis

To estimate the association between self-perceived oral health indicators and ethnic origin in Colombia, a cross-sectional study (Information from the 2007 National Public Health Survey) was conducted. Variables: belonging to an ethnic group (Exposure); oral health indicators (Outcomes); sex, age, education and self-rated health (control). Analyses were carried out separately for men (M) and women (W). The association between the exposure variable and the outcomes was estimated by means of adjusted odds ratio (OR) with confidence intervals (95 % CI) using logistic regression. Men were more likely to report gum bleeding (aOR 1.78; 95 % CI 1.44–2.23) and dental caries (aOR 1.69; 95 % CI 1.42–2.02), while women were more likely to report unmet dental needs (aOR 1.43; 95 % CI 1.27–1.49) and dental caries (aOR 1.34; 95 % CI 1.22–1.47). Indigenous and Palenquero were more likely to report most of the indicators analyzed. Minority ethnic groups in Colombia were at risk to report oral health problems.     

Symptoms Associated with Pregnancy Complications Along the Thai-Burma Border: The Role of Conflict Violence and Intimate Partner Violence

To assess the association between lifetime violence victimization and self-reported symptoms associated with pregnancy complications among women living in refugee camps along the Thai-Burma border. Cross-sectional survey of partnered women aged 15–49 years living in three refugee camps who reported a pregnancy that resulted in a live birth within the past 2 years with complete data (n = 337). Variables included the lifetime prevalence of any violence victimization, conflict victimization, intimate partner violence (IPV) victimization, self-reported symptoms of pregnancy complications, and demographic covariates. Logistic generalized estimating equations, accounting for camp-level clustering, were used to assess the relationships of interest. Approximately one in six women (16.0 %) reported symptoms related to pregnancy complications for their most recent birth within the last 2 years and 15 % experienced violence victimization. In multivariable analyses, any form of lifetime violence victimization was associated with 3.1 times heightened odds of reporting symptoms (95 % CI 1.8–5.2). In the final adjusted model, conflict victimization was associated with a 3.0 increase in odds of symptoms (95 % CI 2.4–3.7). However, lifetime IPV victimization was not associated with symptoms, after accounting for conflict victimization (aOR: 1.8; 95 % CI 0.4–9.0). Conflict victimization was strongly linked with heightened risk of self-reported symptoms associated with pregnancy complications among women in refugee camps along the Thai-Burma border. Future research and programs should consider the long-term impacts of conflict victimization in relation to maternal health to better meet the needs of refugee women.     

Effects of Pre-pregnancy Obesity,Race/Ethnicity and Prematurity

To investigate the association between maternal pre-pregnancy obesity, race/ethnicity and prematurity. Retrospective cohort study of maternal deliveries at a single regional center from 2009 to 2010 time period (n = 11,711). Generalized linear models were used for the analysis to estimate an adjusted odds ratio with 95 % confidence interval of the association between maternal pre-pregnancy obesity, race/ethnicity and prematurity. Analysis controlled for diabetes, chronic hypertension, previous preterm birth, smoking and insurance status. The demographics of the study population were as follows, race/ethnicity had predominance in the White/Non-Hispanic population with 60.1 %, followed by the Black/Non-Hispanic population 24.2 %, the Hispanic population with 10.3 % and the Asian population with 5.4 %. Maternal pre-pregnancy weight showed that the population with a normal body mass index (BMI) was 49.4 %, followed by the population being overweight with 26.2 %, and last, the population which was obese with 24.4 %. Maternal obesity increased the odds of prematurity in the White/Non-Hispanic, Hispanic and Asian population (aOR 1.40, CI 1.12–1.75; aOR 2.20, CI 1.23–3.95; aOR 3.07, CI 1.16–8.13, respectively). Although the Black/Non-Hispanic population prematurity rate remains higher than the other race/ethnicity populations, the Black/Non-Hispanic population did not have an increased odds of prematurity in obese mothers (OR 0.87; CI 0.68–1.19). Unlike White/Non-Hispanic, Asian and Hispanic mothers, normal pre-pregnancy BMI in Black/Non-Hispanic mothers was not associated with lower odds for prematurity. The odds for mothers of the White/Non-Hispanic, Hispanic and Asian populations, for delivering a premature infant, were significantly increased when obese. Analysis controlled for chronic hypertension, diabetes, insurance status, prior preterm birth and smoking. Obesity is a risk factor for prematurity in the White/Non-Hispanic, Asian and Hispanic population, but not for the Black/Non-Hispanic population. The design and evaluation of weight-based maternal health programs that aggregate race/ethnicity may not be sufficient. The optimal method to address maternal pre-pregnancy and intra-pregnancy weight-related health disorders may need to be stratified along race/ethnicity adjusted strategies and goals. However, a more global preventative strategy that encompasses the social determinants of health may be needed to reduce the higher rates of prematurity among the Black/Non-Hispanic population.     

Short interpregnancy interval and adverse birth outcomes in women of advanced age: a population-based study

Purpose

Short interpregnancy interval (IPI) has been linked with adverse birth outcomes. However, the association in advanced age women needs further investigation. This study aims to examine the association between short IPI and adverse birth outcomes including preterm birth, post-term birth, low birth weight, and macrosomia, in a population of advanced age U.S. women.

Measuring Dosage: A Key Factor When Assessing the Relationship Between Prenatal Case Management and Birth Outcomes

To assess whether a measure of prenatal case management (PCM) dosage is more sensitive than a dichotomous PCM exposure measure when evaluating the effect of PCM on low birthweight (LBW) and preterm birth (PTB). We constructed a retrospective cohort study (N = 16,657) of Iowa Medicaid-insured women who had a singleton live birth from October 2005 to December 2006; 28 % of women received PCM. A PCM dosage measure was created to capture duration of enrollment, total time with a case manager, and intervention breadth. Propensity score (PS)-adjusted odds ratios (ORs), and 95 % confidence intervals (95 % CIs) were calculated to assess the risk of each outcome by PCM dosage and the dichotomous PCM exposure measure. PS-adjusted ORs of PTB were 0.88 (95 % CI 0.70–1.11), 0.58 (95 % CI 0.47–0.72), and 1.43 (95 % CI 1.23–1.67) for high, medium, and low PCM dosage, respectively. For LBW, the PS-adjusted ORs were 0.76 (95 % CI 0.57–1.00), 0.64 (95 % CI 0.50–0.82), and 1.36 (95 % CI 1.14–1.63), for high, medium, and low PCM dosage, respectively. The PCM dichotomous participation measure was not significantly associated with LBW (OR = 0.95, 95 % CI 0.82–1.09) or PTB (0.97, 95 % CI 0.87–1.10). The reference group in each analysis is No PCM. PCM was associated with a reduced risk of adverse pregnancy outcomes for Medicaid-insured women in Iowa. PCM dosage appeared to be a more sensitive measure than the dichotomous measure of PCM participation.     

Effect of Modifiable Risk Factors on Preterm Birth: A Population Based-Cohort

Objectives The purpose of this study is to evaluate the prevalence, impact, and interaction of short interpregnancy interval (IPI), pre-pregnancy body mass index (BMI) category, and pregnancy weight gain (PWG) on the rate of preterm birth. Methods This is a population-based retrospective cohort study using vital statistics birth records from 2006 to 2011 in OH, US, analyzing singleton live births to multiparous mothers with recorded IPI (n?=?393,441). Preterm birth rate at <37 weeks gestational age was compared between the referent pregnancy (defined as normal pre-pregnancy maternal BMI, IPI of 12–24 months, and Institute of Medicine (IOM) recommended PWG) and those with short or long IPI, abnormal BMI (underweight, overweight, and obese), and high or low PWG (under or exceeding IOM recommendations). Results Only 6?% of the women in this study had a referent pregnancy, with a preterm birth rate of 7.6?% for this group. Short IPIs of <6 and 6–12 months were associated with increased rates of preterm birth rate to 12.9 and 10.4?%, respectively. Low PWG compared to IOM recommendations for pre-pregnancy BMI class was also associated with increased preterm birth rate of 13.2?% for all BMI classes combined. However, the highest rate of preterm birth of 25.2?% occurred in underweight women with short IPI and inadequate weight gain with _adjOR 3.44 (95?% CI 2.80, 4.23). The fraction of preterm births observed in this cohort that can be attributed to short IPIs is 5.9?%, long IPIs is 8.3?%, inadequate PWG is 7.5?%, and low pre-pregnancy BMI is 2.2?%. Conclusions Our analysis indicates that a significant proportion of preterm births in Ohio are associated with potentially modifiable risk factors. These data suggest public health initiatives focused on preterm birth prevention could include counseling and interventions to optimize preconception health and prenatal nutrition.     

Prevalence and Risk Factors for Postpartum Depressive Symptoms Among Women Enrolled in WIC

The objectives of this study were to determine the prevalence and correlates of postpartum depressive symptoms (PDS) among women with a recent live birth and specifically among women participating in and eligible for the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Pregnancy Risk Assessment and Monitoring System data from 22 states in 2006–2008 (n = 75,234) were used to estimate the prevalence of PDS using a two-question screener. Associations between PDS and respondent demographics, risk factors and behaviors, and WIC program eligibility and participation were assessed using logistic regression. Overall prevalence of PDS was 13.8 %:19.8 % among WIC participants, 16.3 % among non-participants eligible for WIC, and 6.8 % of women not eligible for the program. PDS prevalence was higher among younger, less educated, and poorer women, as well as those engaging in risky behaviors during pregnancy (smoking and binge drinking), and those with an unintended pregnancy and who experienced intimate partner violence during pregnancy. Controlling for these factors, the odds of PDS were no different between WIC participants and women eligible but not participating in the program (aOR 1.08, 95 % CI 0.97–1.22), but WIC enrollees were significantly more likely than ineligible women to report PDS (aOR 1.65, 95 % CI 1.39–1.95). WIC serves more than 1 million pregnant women each year, one-fifth of whom may experience PDS. WIC has a unique opportunity to screen and provide referrals to new mothers receiving postpartum WIC benefits.     

Cerebrovascular and ischemic heart disease in young adults born preterm: a population-based Swedish cohort study

Preterm birth is associated with overall cardiovascular mortality in young adulthood, but which specific conditions that underlie this association is unknown. We studied mortality and morbidity from cerebrovascular and ischemic heart disease in individuals born preterm. In a nationwide Swedish study, we included 1,306,943 individuals without congenital malformations born between 1983 and 1995, followed from 15 years of age to December 31st, 2010. Of these, 73,489 (5.6 %) were born preterm (<37 weeks of gestation). Cox proportional hazards regression analysis was used to calculate hazard ratios (HR) with 95 % confidence intervals (CI), after adjusting for maternal characteristics and birth weight for gestational age. Of 955 incident cases of cerebrovascular disease, 58 (6.1 %) occurred in preterm born subjects. The corresponding numbers of ischemic heart disease cases were 180 and 13 (7.2 %), respectively. Birth before 32 weeks was associated with a nearly twofold increased risk of cerebrovascular disease; adjusted HR, (95 % CI) = 1.89 (1.01–3.54) compared to term born individuals, whereas individuals born at 32–36 weeks were not at increased risk. Preterm birth was not associated with later ischemic heart disease; no cases of ischemic heart disease were recorded among those born before 32 weeks and the HR (95 % CI) for those born at 32–36 weeks of gestation was 1.45 (0.81–2.57), compared to term-born individuals. Birth before 32 weeks is associated with increased risk of cerebrovascular disease in young adulthood. Our data suggest that cardiovascular health promotion in follow-up programs after very preterm birth may be beneficial.     

Socio-Demographic Correlates of Injection Drug Use Among Male Drug Users: A Cross Sectional Study in Nepal

Drug abuse is one of the major public health problems in Nepal. The objective of this study is to explore the factors responsible for the injecting drug use in Nepal. A cross sectional study was conducted among drug users in Pokhara sub metropolitan city in Nepal. Taking prevalence of 20 % at 95 % confidence interval and 20 % non-response rate, 448 samples were calculated for face to face interviews. Most of the study participants were >24 year’s age. Sixty-one percentage of the participants were unemployed. The largest percentage belonged to Gurung/Rai/Pun (37 %) ethnic groups, and had completed secondary level of education (47.5 %). In the logistic regression analysis occupation, motivating factors for drug use, ever been to custody, age at first drug use, age at first sex, money spent on drugs, ever been rehabilitated and age of the respondents showed a statistically significant association with injecting drug use status. The respondents having business [Adjusted Odds ratio (aOR) 4.506, 95 % CI (1.677–12.104)], service [aOR 2.698, 95 % CI (a1.146-6.355], having tragedy/turmoil [aOR 3.867, 95 % CI (1.596–9.367)], family problem [aOR 2.010, 95 % CI (2.010–53.496)], had sex at >19 years [aOR 1.683, 95 % CI (1.017–2.785)], rehabilitated >2 times [aOR 4.699, 95 % CI (1.401–15.763)], >24 years age group [aOR 1.741, 95 % CI (1.025–2.957)] had higher odds of having injecting habits. Having money spent on drugs >3,000 NRs (300 USD) [aOR 0.489, 95 %CI (0.274–0.870), not been to custody (aOR 0.330, 95 %CI (0.203–0.537)] and having curiosity for drug use [aOR 0.147, 95 % CI (0.029–0.737)] were found to be protective for injecting drug use. This study recommends the harm reduction program specifically focused on drug users of occupational groups like business, service and the youths through public health actions to stop transiting them to injecting drug use.     

Deployment and Adverse Pregnancy Outcomes: Primary Findings and Methodological Considerations

Objective To characterize the pregnancy outcomes of women Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans including prevalence of preterm delivery, low birth weight, and macrosomia, and to highlight methodological limitations that can impact findings. Methods A retrospective cohort study was conducted starting in 2014 analyzing data from the 2009 to 2011 National Health Study for a New Generation of US Veterans, which sampled Veterans deployed and not deployed to OIF/OEF. All pregnancies resulting in a live birth were included, and categorized as occurring among non-deployers, before deployment, during deployment, or after deployment. Outcomes included preterm birth, low birth weight, and macrosomia. The association of deployment with selected outcomes was estimated using separate general estimating equations to account for lack of outcome independence among women contributing multiple pregnancies. Adjustment variables included maternal age at outcome, and race/ethnicity. Results There were 2276 live births (191 preterm births, 153 low birth weight infants, and 272 macrosomic infants). Compared with pregnancies before deployment, pregnancies among non-deployers and those after deployment appeared to have greater risk of preterm birth [non-deployers: odds ratio (OR) = 2.16, 95 % confidence interval (CI) 1.25, 3.72; after deployment: OR = 1.90, 95 % CI 0.90, 4.02]. A similar pattern was observed for low birth weight. No association of deployment with macrosomia was detected. Discussion Compared with non-deployers, those who eventually deploy appear to have better pregnancy outcomes prior to deployment, but this advantage is no longer apparent after deployment. Non-deployers may not be an appropriate reference group to study the putative health impacts of deployment on pregnancy outcomes.     

Estimated Number of Preterm Births and Low Birth Weight Children Born in the United States Due to Maternal Binge Drinking

The objective of this study was to estimate the aggregate burden of maternal binge drinking on preterm birth (PTB) and low birth weight (LBW) across American sociodemographic groups in 2008. To estimate the aggregate burden of maternal binge drinking on preterm birth (PTB) and low birth weight (LBW) across American sociodemographic groups in 2008. A simulation model was developed to estimate the number of PTB and LBW cases due to maternal binge drinking. Data inputs for the model included number of births and rates of preterm and LBW from the National Center for Health Statistics; female population by childbearing age groups from the U.S. Census; increased relative risks of preterm and LBW deliveries due to maternal binge drinking extracted from the literature; and adjusted prevalence of binge drinking among pregnant women estimated in a multivariate logistic regression model using Behavioral Risk Factor Surveillance System survey. The most conservative estimates attributed maternal binge drinking to 8,701 (95 % CI: 7,804–9,598) PTBs (1.75 % of all PTBs) and 5,627 (95 % CI 5,121–6,133) LBW deliveries in 2008, with 3,708 (95 % CI: 3,375–4,041) cases of both PTB and LBW. The estimated rate of PTB due to maternal binge drinking was 1.57 % among all PTBs to White women, 0.69 % among Black women, 3.31 % among Hispanic women, and 2.35 % among other races. Compared to other age groups, women ages 40–44 had the highest adjusted binge drinking rate and highest PTB rate due to maternal binge drinking (4.33 %). Maternal binge drinking contributed significantly to PTB and LBW differentially across sociodemographic groups.
