Postnatal Depressive Symptoms Among Mothers and Fathers of Infants Born Preterm: Prevalence and Impacts on Children's Early Cognitive Function
OBJECTIVE:
Preterm birth is associated with lower cognitive functioning. One potential pathway is postnatal parental depression. The authors assessed depressive symptoms in mothers and fathers after preterm birth, and identified the impacts of both prematurity and parental depressive symptoms on children's early cognitive function.
METHOD:
Data were from the nationally representative Early Childhood Longitudinal Study, Birth Cohort (n = 5350). Depressive symptoms at 9 months were assessed by the Center for Epidemiologic Studies Depression Scale (CESD) and children's cognitive function at 24 months by the Bayley Short Form, Research Edition. Weighted generalized estimating equation models examined the extent to which preterm birth, and mothers' and fathers' postnatal depressive symptoms impacted children's cognitive function at 24 months, and whether the association between preterm birth and 24-month cognitive function was mediated by parental depressive symptoms.
RESULTS:
At 9 months, fathers of very preterm (<32 weeks gestation) and moderate/late preterm (32-37 weeks gestation) infants had higher CESD scores than fathers of term-born (â„37 weeks gestation) infants (p value = .02); preterm birth was not associated with maternal depressive symptoms. In multivariable analyses, preterm birth was associated with lower cognitive function at 24 months; this association was unaffected by adjustment for parental depressive symptoms. Fathers', but not mothers', postnatal depressive symptoms predicted lower cognitive function in the fully adjusted model (ÎČ = -0.11, 95% confidence interval, -0.18 to -0.03).
CONCLUSION:
Fathers of preterm infants have more postnatal depressive symptomology than fathers of term-born infants. Fathers' depressive symptoms also negatively impact children's early cognitive function. The national findings support early identification and treatment of fathers of preterm infants with depressive symptoms

Gestational weight gain and child adiposity at age 3 years
OBJECTIVE The purpose of this study was to examine the associations of gestational weight gain with child adiposity. STUDY DESIGN Using multivariable regression, we studied associations of total gestational weight gain and weight gain according to 1990 Institute of Medicine guidelines with child outcomes among 1044 mother-child pairs in Project Viva. RESULTS Greater weight gain was associated with higher child body mass index z-score (0.13 units per 5 kg [95% CI, 0.08, 0.19]), sum of subscapular and triceps skinfold thicknesses (0.26 mm [95% CI, 0.02, 0.51]), and systolic blood pressure (0.60 mm Hg [95% CI, 0.06, 1.13]). Compared with inadequate weight gain (0.17 units [95% CI, 0.01, 0.33]), women with adequate or excessive weight gain had children with higher body mass index z-scores (0.47 [95% CI, 0.37, 0.57] and 0.52 [95% CI, 0.44, 0.61], respectively) and risk of overweight (odds ratios, 3.77 [95% CI: 1.38, 10.27] and 4.35 [95% CI: 1.69, 11.24]). CONCLUSION New recommendations for gestational weight gain may be required in this era of epidemic obesity
Need for Early Interventions in the Prevention of Pediatric Overweight: A Review and Upcoming Directions
Childhood obesity is currently one of the most prevailing and challenging public health issues among industrialized countries and of international priority. The global prevalence of obesity poses such a serious concern that the World Health Organization (WHO) has described it as a âglobal epidemic.â Recent literature suggests that the genesis of the problem occurs in the first years of life as feeding patterns, dietary habits, and parental feeding practices are established. Obesity prevention evidence points to specific dietary factors, such as the promotion of breastfeeding and appropriate introduction of nutritious complementary foods, but also calls for attention to parental feeding practices, awareness of appropriate responses to infant hunger and satiety cues, physical activity/inactivity behaviors, infant sleep duration, and family meals. Interventions that begin at birth, targeting multiple factors related to healthy growth, have not been adequately studied. Due to the overwhelming importance and global significance of excess weight within pediatric populations, this narrative review was undertaken to summarize factors associated with overweight and obesity among infants and toddlers, with focus on potentially modifiable risk factors beginning at birth, and to address the need for early intervention prevention
Nutrition provider confidence in the Massachusetts Childhood Obesity Research Demonstration (MA-CORD) study
Objective:
The multi-sector, multi-level Massachusetts Childhood Obesity Research Demonstration (MA-CORD) study resulted in improvements in obesity risk factors among children age 2-4âŻyears enrolled in the Special Supplemental Nutrition program for Women, Infants, and Children (WIC). The goal of this study was to examine whether the MA-CORD intervention increased WIC provider confidence in their ability to identify childhood obesity and obesity-related behaviors.
Methods:
As part of the MA-CORD intervention conducted from 2012 to 2015, we implemented WIC practice changes focused on childhood obesity prevention within two Massachusetts communities. We examined changes in provider confidence to assess childhood obesity risk factors and practice frequency among WIC practices located in MA-CORD intervention communities over a 3-year period, compared to non-intervention sites. We measured provider confidence on a continuous scale using questions previously developed to assess provider and parent confidence to make weight-related behavior change (range 0 to 24).
Results:
There were 205 providers at baseline and 165 at follow-up. WIC providers at intervention sites reported greater confidence in their ability to identify childhood obesity and obesity-related behaviors compared to the usual care sites (ÎČâŻ=âŻ1.01, standard errorâŻ=âŻ0.13). These findings persisted after adjusting for provider gender, years in practice, highest education level, and WIC position.
Conclusions:
The MA-CORD intervention was associated with increased WIC provider confidence to assess children's obesity risk. Interventions that increase confidence in assessing obesity-related behaviors may have salutary effects within WIC programs that serve low-income families
Correlations among adiposity measures in school-aged children
BACKGROUND:
Given that it is not feasible to use dual x-ray absorptiometry (DXA) or other reference methods to measure adiposity in all pediatric clinical and research settings, it is important to identify reasonable alternatives. Therefore, we sought to determine the extent to which other adiposity measures were correlated with DXA fat mass in school-aged children. METHODS:
In 1110 children aged 6.5-10.9 years in the pre-birth cohort Project Viva, we calculated Spearman correlation coefficients between DXA (n=875) and other adiposity measures including body mass index (BMI), skinfold thickness, circumferences, and bioimpedance. We also computed correlations between lean body mass measures. RESULTS:
50.0% of the children were female and 36.5% were non-white. Mean (SD) BMI was 17.2 (3.1) and total fat mass by DXA was 7.5 (3.9) kg. DXA total fat mass was highly correlated with BMI (r(s)=0.83), bioimpedance total fat (r(s)=0.87), and sum of skinfolds (r(s)=0.90), and DXA trunk fat was highly correlated with waist circumference (r(s)=0.79). Correlations of BMI with other adiposity indices were high, e.g., with waist circumference (r(s)=0.86) and sum of subscapular plus triceps skinfolds (r(s)=0.79). DXA fat-free mass and bioimpedance fat-free mass were highly correlated (r(s)=0.94). CONCLUSIONS:
In school-aged children, BMI, sum of skinfolds, and other adiposity measures were strongly correlated with DXA fat mass. Although these measurement methods have limitations, BMI and skinfolds are adequate surrogate measures of relative adiposity in children when DXA is not practical
Healthy Habits Happy Homes Scotland (4HS) feasibility study : translation of a home-based early childhood obesity prevention intervention evaluated using RE-AIM framework
Objective Healthy Habits, Happy Homes (4H) is a home-based, pre-school childhood obesity prevention intervention which demonstrated efficacy in North America which we translated to Scotland (4HS) by considering contextual factors and adapting study design. RE-AIM Framework was used to assess 1) extent to which development of 4HS intervention (including recruitment) was participatory and inclusive; 2) feasibility of translating a complex public health intervention from one setting to another; 3) extent to which translation was pragmatic and 4) fidelity of intervention to the principles of Motivational Interviewing (MI). Study design Feasibility testing, process evaluation and measurements of intervention fidelity were undertaken to evaluate the translation of 4H to an economically deprived area of Scotland (4HS). Methods 4HS study processes; participatory approach, recruitment methods, level of pragmatism were evaluated using the RE-AIM framework. Qualitative and quantitative measures identified key implementation features and functioning of 4HS intervention. Fidelity MI principles was determined through coding of audiotapes using Motivation Interviewing Treatment Integrity (MITI) code. Results Key facilitators for positive impact with families, included: inclusive recruitment methods, appropriate channels of communication and correspondence (Reach) with n â= â126 enquiries and n â= â26 (21%) families recruited. Positive links with local parents and community workers integral to the research process at n â= â9 meetings (Effectiveness). 61.5% of families lived in the most deprived data zone in Scotland, 23% were one parent families, thus awareness and consideration of local contextual factors (Adoption) and locally relevant materials were important. 4HS was feasible to deliver, pragmatic in nature and intervention demonstrated good fidelity to MI (Implementation). Conclusion Translation of 4H from North America to Scotland was successful. Future studies should consider implementation of 4HS approach within routine practice within the UK (practice based evidence) or through thoughtful evaluation in a future trial (evidence based practice)
Association of Vitamin E Intake at Early Childhood with Alanine Aminotransferase Levels at Mid-Childhood
The extent to which vitamin E (alpha-tocopherol) intake early in childhood is associated with alanine aminotransferase (ALT) level later in childhood is unknown. The objective of this research is to test the hypothesis that higher alpha-tocopherol intake during early childhood is associated with lower odds of elevated ALT levels during mid-childhood, and to examine how body mass index (BMI) influences these relationships. We studied 528 children in Project Viva. Mothers reported child dietary intake at early childhood visits (median 3.1 years) using a validated food frequency questionnaire. At mid-childhood (median 7.6 years), we collected child blood and anthropometric data. The main outcome was elevated sex-specific mid-childhood ALT level (â„ 22.1 units/liter for females andââ„â25.8 units/liter for males). In multivariable logistic regression models, we assessed the association of energy-adjusted alpha-tocopherol intake with ALT levels, adjusting for child age, sex, race/ethnicity, diet, and age-adjusted, sex-specific BMIz at mid-childhood. Among children in this study, 48% were female, 63% were non-Hispanic white, 19% were non-Hispanic black, and 4% Hispanic/Latino. Mean alpha-tocopherol intake was 3.7±1.0 mg/day (range 1.4-9.2) at early childhood. At mid-childhood, mean BMIz was 0.41±1.0 units and 22% had an elevated ALT level. In multivariable-adjusted logistic regression models, children with higher early childhood vitamin E intake had lower odds of elevated mid-childhood ALT [adjusted odds ratio (AOR) 0.62 (95% CI: 0.39-0.99)] for quartiles 2-4 compared with the lowest quartile of intake. Findings persisted after accounting for early childhood diet [0.62 (0.36, 1.08)] and were strengthened after additionally accounting for mid-childhood BMIz [0.56 (0.32, 0.99)].
Conclusion: In this cohort, higher early childhood intake of alpha-tocopherol was associated with lower odds of elevated mid-childhood ALT level

Characteristics of Walkable Built Environments and BMI z-Scores in Children: Evidence from a Large Electronic Health Record Database
Background: Childhood obesity remains a prominent public health problem. Walkable built environments may prevent excess weight gain. Objectives: We examined the association of walkable built environment characteristics with body mass index (BMI) z-score among a large sample of children and adolescents. Methods: We used geocoded residential address data from electronic health records of 49,770 children and adolescents 4 to < 19 years of age seen at the 14 pediatric practices of Harvard Vanguard Medical Associates from August 2011 through August 2012. We used eight geographic information system (GIS) variables to characterize walkable built environments. Outcomes were BMI z-score at the most recent visit and BMI z-score change from the earliest available (2008â2011) to the most recent (2011â2012) visit. Multivariable models were adjusted for child age, sex, race/ethnicity, and neighborhood median household income. Results: In multivariable cross-sectional models, living in closer proximity to recreational open space was associated with lower BMI z-score. For example, children who lived in closest proximity (quartile 1) to the nearest recreational open space had a lower BMI z-score (ÎČ = â0.06; 95% CI: â0.08, â0.03) compared with those living farthest away (quartile 4; reference). Living in neighborhoods with fewer recreational open spaces and less residential density, traffic density, sidewalk completeness, and intersection density were associated with higher cross-sectional BMI z-score and with an increase in BMI z-score over time. Conclusions: Overall, built environment characteristics that may increase walkability were associated with lower BMI z-scores in a large sample of children. Modifying existing built environments to make them more walkable may reduce childhood obesity. Citation: Duncan DT, Sharifi M, Melly SJ, Marshall R, Sequist TD, Rifas-Shiman SL, Taveras EM. 2014.

The cost of a primary care-based childhood obesity prevention intervention
Background: United States pediatric guidelines recommend that childhood obesity counseling be conducted in the primary care setting. Primary care-based interventions can be effective in improving health behaviors, but also costly. The purpose of this study was to evaluate the cost of a primary care-based obesity prevention intervention targeting children between the ages of two and six years who are at elevated risk for obesity, measured against usual care. Methods: High Five for Kids was a cluster-randomized controlled clinical trial that aimed to modify childrenâs nutrition and TV viewing habits through a motivational interviewing intervention. We assessed visit-related costs from a societal perspective, including provider-incurred direct medical costs, provider-incurred equipment costs, parent time costs and parent out-of-pocket costs, in 2011 dollars for the intervention (n = 253) and usual care (n = 192) groups. We conducted a net cost analysis using both societal and health plan costing perspectives and conducted one-way sensitivity and uncertainty analyses on results. Results: The total costs for the intervention group and usual care groups in the first year of the intervention were 64,522, 12,192 (95% CI [13,174]). The mean costs for the intervention and usual care groups were 255, 63 (95% CI [69]) per child, respectively, for a incremental difference of 191, $202]) per child. Children in the intervention group attended a mean of 2.4 of a possible 4 in-person visits and received 0.45 of a possible 2 counseling phone calls. Provider-incurred costs were the primary driver of cost estimates in sensitivity analyses. Conclusions: High Five for Kids was a resource-intensive intervention. Further studies are needed to assess the cost-effectiveness of the intervention relative to other pediatric obesity interventions. Trial registration ClinicalTrials.gov Identifier: NCT00377767
The Influence of Antenatal Partner Support on Pregnancy Outcomes
BACKGROUND:
While there has been considerable attention given to the multitude of maternal factors that contribute to perinatal conditions and poor birth outcomes, few studies have aimed to understand the impact of fathers or partners. We examined associations of antenatal partner support with psychological variables, smoking behavior, and pregnancy outcomes in two socioeconomically distinct prebirth cohorts.
MATERIALS AND METHODS:
Data were from 1764 women recruited from an urban-suburban group practice (Project Viva) and 877 women from urban community health centers (Project ACCESS), both in the Boston area. Antenatal partner support was assessed by the Turner Support Scale. Multivariable linear and logistic regression analyses determined the impact of low antenatal partner support on the outcomes of interest.
RESULTS:
In early pregnancy, 6.4% of Viva and 23.0% of ACCESS participants reported low partner support. After adjustment, low partner support was cross-sectionally associated with high pregnancy-related anxiety in both cohorts (Viva AOR 1.8; 95% CI: 1.0-3.4 and ACCESS AOR 1.9; 95% CI: 1.1-3.3) and with depression in ACCESS (AOR 1.9; 95% CI: 1.1-3.3). In Viva, low partner support was also related to depression mid-pregnancy (AOR 3.1; 95% CI: 1.7-5.7) and to smoking (AOR 2.2; 95% CI: 1.3-3.8). Birth weight, gestational age, and fetal growth were not associated with partner support.
CONCLUSIONS:
This study of two economically and ethnically distinct cohorts in the Boston area highlights higher levels of antenatal anxiety, depression, and smoking among pregnant women who report low partner support. Partner support may be an important and potentially modifiable target for interventions to improve pregnancy outcomes
