Defining longitudinal trajectory of body mass index percentile and predicting childhood obesity: methodologies and findings in the Boston Birth Cohort.

Background: Overweight or obesity (OWO) in school-age childhood tends to persist into adulthood. This study aims to address a critical need for early identification of children at high risk of developing OWO by defining and analyzing longitudinal trajectories of body mass index percentile (BMIPCT) during early developmental windows. Methods: We included 3029 children from the Boston Birth Cohort (BBC) with repeated BMI measurements from birth to age 18 years. We applied locally weighted scatterplot smoothing with a time-limit scheme and predefined rules for imputation of missing data. We then used time-series K-means cluster analysis and latent class growth analysis to define longitudinal trajectories of BMIPCT from infancy up to age 18 years. Then, we investigated early life determinants of the BMI trajectories. Finally, we compared whether using early BMIPCT trajectories performs better than BMIPCT at a given age for predicting future risk of OWO. Results: After imputation, the percentage of missing data ratio decreased from 36.0% to 10.1%. We identified four BMIPCT longitudinal trajectories: early onset OWO; late onset OWO; normal stable; and low stable. Maternal OWO, smoking, and preterm birth were identified as important determinants of the two OWO trajectories. Our predictive models showed that BMIPCT trajectories in early childhood (birth to age 1 or 2 years) were more predictive of childhood OWO (age 5-10 years) than a single BMIPCT at age 1 or 2 years. Conclusions: Using longitudinal BMIPCT data from birth to age 18 years, this study identified distinct BMIPCT trajectories, examined early life determinants of these trajectories, and demonstrated their advantages in predicting childhood risk of OWO over BMIPCT at a single time point.

Maternal folate status and placental vascular malperfusion: Findings from a high-risk US minority birth cohort.

INTRODUCTION: Maternal folate deficiency was associated with preeclampsia (PE) and PE was associated with placental maternal vascular malperfusion (MVM). However, no study has examined the association of maternal folate status with placental MVM. METHODS: We examined the association of maternal folate status and placental MVM in the Boston Birth Cohort. Primary exposure variables were maternal self-reported multivitamin supplement (<2, 3-5, >5 times/week) per trimester; and plasma folate levels (nmol/L) after birth. Primary outcome was presence/absence of placental MVM defined by the Amsterdam Placental Workshop Group standard classification. Covariates included demographics, chronic hypertension, clinically diagnosed PE, eclampsia and HELLP syndrome, gestational and pre-gestational diabetes, overweight/obesity, maternal cigarette smoking and alcohol use. Associations between folate and placental MVM were evaluated using multivariate logistic regressions. RESULTS: Of 3001 mothers in this study, 18.8% of mothers had PE, 37.5% had MVM. Mothers with the lowest self-reported frequency of folate intake had the highest risk of MVM (OR 1.45, 95% CI 1.03-2.05), after adjusting for the covariates. Consistently, among a subset of 939 mothers with plasma folate levels, folate insufficiency was associated with increased risk of MVM (OR 1.65, 95% CI 1.03-2.63), after adjusting for the covariables. As expected, mothers with low folate and placental MVM had highest rates of PE compared to those of high folate and no MVM (p < 0.001). DISCUSSION: In this high-risk birth cohort, low maternal folate status was associated with increased risk of placental MVM. Further investigation should explore the association between folate status, placental findings and the great obstetrical syndrome.

Birth outcomes across the spectrum of maternal age: dissecting aging effect versus confounding by social and medical determinants.

BACKGROUND: Given the trend of increasing maternal age and associated adverse reproductive outcomes in the US, this study aimed to assess whether this association is due to an independent aging or confounded by sociodemographic, biomedical, or behavioral determinants in a predominantly Black US population. METHODS: Data was from 8509 women enrolled in the Boston Birth Cohort. Adverse reproductive outcomes included spontaneous preterm delivery, cesarean delivery, and low birth weight. Covariates included sociodemographic (parity, race/ethnicity, education, marital status, income, receipt of public assistance, nativity); biomedical (obesity, hypertensive disorders, diabetes mellitus); and behavioral (consistent intake of multivitamin supplements, support from father of baby, support from family, major stress in pregnancy, cigarette smoking, alcohol intake). Analysis included Lowess and marginal probability plots, crude and adjusted sequential logistic regression models to examine age-outcome associations and to what degree the association can be explained by the above covariables. RESULT: Overall, the study sample had high levels of spontaneous preterm birth (18%), cesarean delivery (33%) and low birth weight (26%). Unadjusted models showed no significant difference odds of spontaneous preterm birth by maternal age but higher odds of cesarean section (aOR: 1.77, 95% CI: 1.60, 1.95) and low birth weight (aOR: 1.15, 95% CI: 1.04, 1.28) among women 30 years or older. Adjustment for sociodemographic factors, biomedical conditions and behavioral factors revealed higher odds of spontaneous preterm birth: (aOR: 1.30, 95% CI: 1.14, 1.49), cesarean section deliveries (aOR: 1.68, 95% CI: 1.51, 1.87) and low birth weight (aOR: 1.36, 95% CI: 1.21, 1.53). Across all ages, optimal BMI status and consistent multivitamin supplement intake were protective of spontaneous preterm birth and low birth weight. CONCLUSION: In this high-risk minority population, we demonstrated that the association between increasing maternal age and adverse pregnancy outcomes was due to an independent aging effect and the presence of confounding by sociodemographic, biomedical, and behavioral factors. Some modifiable risk factors to counteract aging effect, include optimizing BMI and consistent intake of multivitamin supplement. A fundamental change in how care is provided to women, particularly low income Black women, is needed with emphasis on the protective role of optimal nutritional status.

Family-Oriented Social Service Touchpoints as Opportunities to Enhance Diabetes Screening following a History of Gestational Diabetes.

INTRODUCTION: Women with a history of gestational diabetes (GDM) are at increased risk for type 2 diabetes and thus require regular follow-up screening for diabetes; however, many women do not receive this screening, and in particular low-income women face disparities in receipt of recommended follow-up care. While these women may have limited access to healthcare following pregnancy, they may more regularly access social service programs that serve themselves or their young children. Leveraging these social service touchpoints could broaden opportunities to improve follow-up care receipt among women with a history of GDM. To describe these potential opportunities, we used national representative data to characterize diabetes screening needs among women with a history of GDM who access the Special supplemental nutrition program for Women, Infants and Children (WIC) or Head Start programming for their young children. METHODS: We analyzed national representative data from the National Health Interview Survey from calendar years 2016 and 2017. Our analytic sample included women aged 18 to 45 years who were linked to at least one of their children in the dataset and who had a self-reported history of GDM but did not have prediabetes or diabetes. We examined the proportion of these women who accessed WIC or Head Start who did not report having testing for diabetes within the past 3 years. RESULTS: Of 432 (representing 2,002,675 weighted) women meeting inclusion criteria, 21.7% accessed WIC and 8.7% Head Start. Nearly 1 in 10 women with a history of GDM in either group did not report recent diabetes screening. In sensitivity analyses that excluded likely pregnancy-related testing, 35.0% of women accessing WIC and 21.2% of those accessing Head Start had not had recent screening. DISCUSSION: There is an unmet need for follow-up diabetes screening among women with a history of GDM who access WIC or Head Start services for their young children. Leveraging women's touchpoints with these programs could enhance opportunities to improve recommended diabetes screening among a high-risk population.

Cluster Randomized Trial of a Pre/Interconception Health Intervention for Mothers in Pediatric Visits.

OBJECTIVE: Recognizing that pediatric primary care focuses on family health and is an important location of contact for women of childbearing age, this project assessed the effectiveness of a pre/interconception women's health intervention delivered during pediatric primary care using a cluster randomized trial. METHODS: Pediatric clinicians were randomized to a screening and brief educational intervention group or usual care comparison group. Intervention group clinicians received training on pre/interconception care, including recommended counseling and referral resources for needs identified. Women presenting to primary care with their child ≤12 months were enrolled and assigned to the group corresponding to the assignment of their child's clinician. Mothers seen by clinicians in the intervention group completed a pre/interconception health screening tool and discussed results with their child's clinician during the visit. These mothers were compared to mothers seen by comparison group clinicians who did not receive the screening tool or clinician discussion. All enrolled mothers (Intervention and Comparison) received written preconception health information and a 90-day supply of multivitamins. Primary outcomes at 6 and 12 months post enrollment included contraception use, pregnancy, and access to and use of preventive health care. Secondary outcomes included daily folic acid supplementation, smoking, and substance use. RESULTS: A total of 415 women were enrolled and those who had at least 1 follow-up assessment were included in the analysis (n = 383). There was no significant effect of the intervention on contraceptive use, pregnancy incidence, or use of preventive care. Assignment to the intervention increased the odds of daily folic acid use (odds ratio 1.82, 95% confidence interval 1.25, 2.63) during follow-up. Intervention mothers were less likely to smoke at 6, but not 12 months. CONCLUSIONS: Pediatric visits are an opportune location for addressing maternal health and this intervention demonstrated feasibility and improved outcomes for some but not all outcomes. Attention to maternal health needs in pediatric visits during infancy may be important for maintaining positive pre/interconception health behaviors.

The Next 7 Great Achievements in Pediatric Research.

The "7 Great Achievements in Pediatric Research" campaign noted discoveries in the past 40 years that have improved child and adult health in the United States and around the globe. This article predicts the next 7 great pediatric research advancements, including new immunizations, cancer immunotherapy, genomic discoveries, identification of early antecedents of adult health, impact of specific social-environmental influences on biology and health, quality improvement science, and implementation and dissemination research to reduce global poverty. It is an extraordinary time of new research tools that include electronic health records, technological ability to manage big data and measure "omics," and new functional and structural imaging modalities. These tools will discern mechanisms leading to health and disease with new prevention targets and cures. This article further discusses the challenges and opportunities to accelerate these exciting pediatric research discoveries to improve the lives of children and the adults they will become.

Addressing Parental Health in Pediatrics: Physician Perceptions of Relevance and Responsibility.

Pediatric guidelines recommend that providers address a range of parental health issues; however, adherence to these guidelines has been suboptimal. Drawing on a nationally-representative sample of children's primary care physicians, we examined whether providers view parental issues as relevant to child health and whether they believe it is their personal responsibility to address them. Issues included maternal depression, tobacco use, intimate partner violence, Tdap (tetanus, diphtheria, and acellular pertussis) immunization, family planning, and health insurance. While the majority of respondents endorsed the relevance of these issues to child health, particularly for issues with an established evidencebase, significantly fewer felt responsible for addressing them. Physicians who endorsed relevance or responsibility were almost always more likely to address these issues in their clinical practice. To advance parental health promotion practices, highlighting relevance to pediatric outcomes is an important first step, particularly for novel areas, while understanding what factors influence personal responsibility is necessary for all issues.

Physician Perspectives on Decision Making for Treatment of Pediatric Sleep-Disordered Breathing.

Sleep-disordered breathing (SDB) is prevalent in children and most commonly treated by surgery with adenotonsillectomy. We aimed to learn physician perspectives of social and communication factors that influence decision making for treatment of pediatric SDB. Purposive sampling identified 10 physician key informants across disciplines and practice settings, who participated in semistructured interviews regarding SDB care experiences and communication with parents. Interviews were analyzed using directed qualitative content analysis. Physicians provided a variety of perspectives on decision making for treatment that fell into 3 overarching themes: approach to surgery and alternatives, communication and decision making with families, and sociocultural factors/barriers to care. Perspectives were moderately heterogeneous, suggesting that individual social and relational elements may significantly influence how physicians refer patients and recommend treatment, and how parents choose surgery for this prevalent condition. These findings will inform development of culturally competent communication strategies and support tools to enhance shared decision making for physicians treating children with SDB.

Parent Experience of Care and Decision Making for Children Who Snore.

Importance: Sleep-disordered breathing (SDB) is prevalent and has an impact on the physical and behavioral health of children. Adenotonsillectomy (AT), the primary treatment, is subject to unexplained variation in utilization, which may be reduced by improving physician-patient communication and decision quality for this elective procedure. Objective: To identify factors are associated with parental experience and decision making in pediatric SDB and AT surgery. Design, Setting, and Participants: In this qualitative study, parents of children with prior SDB evaluation participated in semistructured, audiorecorded interviews. Open-ended questions regarded experiences of having a child with SDB, communication with pediatric clinicians and surgeons, and experiences with AT surgery. Recordings were transcribed and analyzed for emergent themes using grounded theory methodology. Eleven parents of children ages 2 to 17 years who had previously been diagnosed or treated for SDB were identified via purposive sampling and interviewed between January and April 2015. Interviews were conducted at locations convenient for the participants and separate from the pediatric clinic. A goal of this study was to ascertain how parents perceived sharing decisions with their physicians. Main Outcomes and Measures: Themes of parental experiences and treatment decision-making processes with pediatric SDB. Results: Overarching themes were inclusive of (1) clinical factors of SDB and AT and (2) clinician interpersonal behaviors and communication. Parents described an urgency that led them to seek evaluation or treatment, including fear that the child would stop breathing, or behavioral and/or cognitive delays. Parents often viewed surgery as a "last resort" and had explored alternate therapies prior to seeing the surgeon. Nearly all parents feared anesthesia more than AT surgery itself. Parents described satisfaction when physicians provided them with options, engaged their child in conversation, depicted SDB visually, and were responsive or accessible to questions. Parents regarded a trusting relationship with their pediatrician, confidence in the surgeon, and inclusion in decision making as important. Conclusions and Relevance: While clinical factors were influential for decision making, interpersonal factors helped parents feel comfortable and influenced their overall experience. Shared decision making, in which parents receive evidence-based information allowing them to accurately perceive risks, benefits, and alternatives about SDB treatment in the setting of trusting clinician-family relationships, may reduce parental decision conflict and improve decision quality toward AT surgery.

Caregiver Health Promotion in Pediatric Primary Care Settings: Results of a National Survey.

OBJECTIVE: To assess practice patterns, barriers, and facilitators related to caregiver health promotion in pediatric primary care settings. STUDY DESIGN: We conducted a mail-based survey of a nationally representative sample of 1000 children's primary care physicians (trained in pediatrics, family medicine, or medicine-pediatrics). We assessed engagement in 6 caregiver health issues (maternal depression, tobacco use, intimate partner violence, family planning, health insurance, and tetanus, diphtheria, and acellular pertussis immunization status) along with barriers and facilitators related to engagement. We used multivariable logistic regression to identify physician and practice correlates of engagement. RESULTS: The response rate was 30%. The majority of respondents (79.3%) regularly addressed at least 3 caregiver health issues during well infant/child visits, most commonly maternal depression, tobacco use, and tetanus, diphtheria, and acellular pertussis immunization immunization status. Screening was the most common activity. In adjusted analyses, pediatricians were less likely to screen for intimate partner violence and family planning compared with other providers. There were no other differences in engagement by physician specialty. Lack of time was the most commonly endorsed barrier (by 85.2% of respondents). Co-location of auxiliary services was the most frequently cited facilitator for the majority of issues. CONCLUSIONS: Children's primary care physicians and their care teams routinely engage in a variety of activities promoting caregiver health, largely independent of training background and despite multiple practice-related barriers. Co-location of auxiliary services could support the efforts of pediatric care teams. Future efforts that investigate care models which address these barriers and facilitators will help to realize the potential of pediatric settings to impact adult health.

Health Behaviors Among Women Using Fertility Treatment.

Objective To describe associated perinatal behaviors among women using fertility treatment. Methods Data were obtained for 12,197 Maryland women who delivered live neonates from 2004 to 2011 and completed the Pregnancy Risk Assessment Monitoring System survey postpartum. We conducted weighted descriptive and multivariable analyses. Results Among 1368 women using fertility treatments, 28.4 % did not take folic acid daily 1 month before pregnancy, 58.1 % consumed alcohol, 16.0 % were binge drinking, and 7.5 % smoked 3 months before pregnancy, and 12.9 % consumed alcohol and 3.7 % smoked during pregnancy. Additionally, among those who consumed alcohol and smoked before pregnancy, 36.0 % and 25.7 %, respectively, reported not receiving prenatal counseling about alcohol use and smoking. Lack of counseling for these women was higher than for women with unintended pregnancies who consumed alcohol (36.0 % vs. 26.3 %, P < .001) or smoked (25.7 % vs. 15.0 %, P < .001). Women using fertility treatments were less likely to have inadequate folic acid intake [adjusted odds ratio (aOR) 0.14, 95 % confidence interval (CI) 0.10-0.18), consume alcohol (aOR 0.52, 95 % CI 0.40-0.69), and smoke (aOR 0.35, 95 % CI 0.21-0.59) before pregnancy, and no statistically significant differences were found during pregnancy for alcohol consumption (aOR 0.89, 95 % CI 0.59-1.33) or smoking (aOR 0.64, 95 % CI 0.28-1.45) compared to women with unintended pregnancies. Conclusion A significant proportion of women using fertility treatments were not practicing recommended perinatal behaviors or receiving prenatal counseling on preventable risk factors. Ongoing counseling before and during pregnancy may be especially effective for optimizing healthy behaviors among these motivated women undergoing often stressful treatments for fertility.

Promoting "Healthy Futures" to Reduce Risk Behaviors in Urban Youth: A Randomized Controlled Trial.

There is increasing evidence of the interconnection between educational and health outcomes. Unfortunately wide disparities exist by both socioeconomic status and race/ethnicity in educational and vocational success. This study sought to promote urban youths' career readiness as a way to reduce involvement in risk behaviors. Two hundred primarily African-American youth (ages 14-21) were recruited from a pediatric primary care clinic. Youth randomized to the intervention received three motivational interviewing sessions focused around expectations and planning for the future. Baseline and 6-month follow-up assessments included measures of career readiness and risk behavior involvement (i.e., physical fighting, alcohol and marijuana use). At 6-months, youth randomized to the intervention condition showed increased confidence in their ability to perform the behaviors needed to reach their college/career goals. Additionally, youth randomized to the intervention arm showed decreased fighting behavior (adjusted rate ratio: .27) and marijuana use (adjusted rate ratio: .61). Assisting urban youth in thinking and planning about their future holds promise as a way to reduce their involvement in risk behaviors. This study also demonstrated that motivational interviewing could be used to promote positive behaviors (i.e., career readiness).

Using the theory of planned behavior to predict aggression and weapons carrying in urban African American early adolescent youth.

Aggressive and weapons carrying behaviors are indicative of youth violence. The theory of planned behavior is used in the current analysis to improve our understanding of violence-related behaviors. We examine the influence of perceived behavioral control (self-control and decision making) as a part of the overall framework for understanding the risk and protective factors for aggressive behaviors and weapons carrying. As the baseline assessment of an intervention trial, survey data were collected on 452 sixth-grade students (50% girls; 96.6% African American; mean age 12.0 years) from urban middle schools. A total of 18.4% carried a weapon in the prior 12 months, with boys more likely to carry a weapon than girls (22.5% vs. 14.2%, p = .02). Of the youth, 78.4% reported aggressive behaviors with no significant differences found between girls (81.3%) and boys (75.5%). In logistic regression models, having peers who engage in problem behaviors was found to be a significant risk factor. Youth with peers who engaged in numerous problem behaviors were five times more likely to be aggressive than those who reported little or no peer problem behaviors. Teens who reported that their parents opposed aggression (odds ratio [OR] = 0.76; confidence interval [CI] = 0.66, 0.88) and who used self-control strategies (OR = 0.59; CI = 0.39, 0.87) were found to report less aggressive behaviors. For weapons carrying, being a girl (OR = 0.56; CI = 0.32, 0.97) and self-control (OR = 0.52; CI = 0.29, 0.92) were protective factors. This study demonstrated that the theory of planned behavior may provide a useful framework for the development of violence prevention programs. Practitioners should consider integrating strategies for developing healthy relationships and improving self-control.

Screening for domestic violence and childhood exposure in families seeking care at an urban pediatric clinic.

In a survey of 133 caregivers in a pediatric clinic, 30 women (23%) disclosed domestic violence, with 2 reporting coercive control but not physical violence. Seventeen women stated that a child had been exposed as well. Domestic violence is not a "private" adult problem; further study of an appropriate pediatric-based screener is needed.

Successful use of a primary care practice-specialty collaboration in the care of an adolescent with chronic fatigue syndrome.

We report on the successful collaborative care of an adolescent with chronic fatigue syndrome between a primary care pediatrician and an academic chronic fatigue syndrome specialist located in different cities. Regular telephone and e-mail communication and clearly defined patient-care roles allowed for timely management of symptoms and marked clinical improvement. We discuss ways to improve the collaboration of primary care and subspecialty physicians for patients with chronic fatigue syndrome and children with special health care needs.

Availability of adolescent health services and confidentiality in primary care practices.

BACKGROUND: Little is known about availability of services and confidential care for adolescents in primary care practices or how availability among pediatric practices compares to that among other primary care practices. The objective of this study was to assess self-reported availability of services for medically emancipated conditions and confidential care in primary care practices, to compare physician responses to those from office staff who answer appointment lines, and to compare availability in pediatric practices to other primary care practice types. METHODS: We conducted a telephone survey of randomly selected practices from the Washington, DC, metropolitan area in pediatrics (Peds), internal medicine (IM), and family medicine (FM). We asked staff who answer appointment lines about availability of services for medically emancipated conditions and confidential appointments for adolescents. Physicians received the same questions via a mail survey. Responses from office staff and physicians in the same practice were linked for comparison. RESULTS: Of 434 practices contacted by telephone, 372 (86%) responded. Of the 615 physicians surveyed from these 372 practices, 264 (43%) from 170 practices responded to the mail survey. Peds practices were less likely than FM and IM practices to offer services for medically emancipated conditions and were less likely than FM practices to offer confidential services to adolescents. Office staff and physicians from FM and IM had higher agreement compared with Peds about availability of services for medically emancipated conditions. Agreement between office staff and physicians about provision of confidential appointments to adolescents was low among all practice types. However, having a written office policy on adolescent confidentiality was significantly associated with agreement between office staff and physicians about availability of confidential services. CONCLUSIONS: Care for medically emancipated conditions and confidential services for adolescents are limited among primary care practices, especially among pediatric practices. All primary care practice types had significant disagreement between office staff and physicians about availability of confidential services to adolescents. Adolescents who call appointment lines are likely to receive inaccurate information about confidentiality policies. Establishing written office policies on adolescent confidentiality may help to improve access to confidential care for adolescents.
