RESUMEN

BACKGROUND: Family-based behavioral treatment (FBT) is an effective intensive health behavior and lifestyle treatment for obesity reduction in children and adolescents, but families have limited access. The purpose of this randomized, pragmatic, comparative effectiveness trial was to examine changes in child relative weight in a 12-month, enhanced standard of care (eSOC) intervention combined with FBT (eSOC+FBT) vs. eSOC alone. METHODS: Children aged 6 to 15 years with obesity, and their primary caregiver, were recruited from primary care clinics. Families were randomized 1:1 to eSOC, a staged approach led by the primary care provider that gradually intensified dependent on a child's response to care and aligns with the American Medical Association guidelines, or the eSOC+FBT arm, which included regular meetings with a health coach for healthy eating, physical activity, positive parenting strategies, and managing social and environmental cues. Both treatments align with the 2023 American Academy of Pediatrics clinical practice guidelines. Assessments occurred at baseline, midpoint (month 6), end-of-intervention (month 12), and follow-up (month 18). Primary outcome was change from baseline to 12 months in child percent overweight (percentage above the median body mass index in the general US population normalized for age and sex). Secondary outcomes were parent weight, child psychosocial factors, heterogeneity of treatment effects, and cardiometabolic risk factors. Exploratory outcomes assessed reach, effectiveness, adoption, implementation, and maintenance. CONCLUSION: This pragmatic trial will generate evidence for the comparative effectiveness of implementing two guidelines-based approaches in primary care for obesity reduction in children and adolescents. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03843424.

RESUMEN

OBJECTIVE: The aim of this substudy within the Treatment Efforts Addressing Child Weight Management by Unifying Patients, Parents, and Providers (TEAM UP) pragmatic clinical trial was to compare the validity of anthropometric measurements collected remotely versus in person (≤7 days apart) among youth with obesity who were 6 to 15 years of age. METHODS: Child (n = 37) weight and height were measured in person by a trained data assessor. These were compared with measurements taken remotely by the child's parent with live videoconferencing observation by a study data assessor. In-person and remote measurements were compared using Bland-Altman plots, Pearson correlations, and two one-sided paired t tests. A priori bounds of acceptability were set at ±0.68 kg to allow for typical weight fluctuations within the 7-day comparison period. RESULTS: Measurements were highly correlated (height: r = 0.991, p < 0.0001; weight: r = 0.999; p = 0.03). For height, two one-sided t tests for upper, t(36) = 3.95, and lower, t(36) = -2.63, bounds (-1, 1) revealed an overall p = 0.006; absolute error was 3.5 cm. For weight, two one-sided t tests for upper, t(36) = 1.93, and lower, t(36) = -7.91, bounds (-0.68, 0.68) revealed an overall p = 0.03; absolute error was 1.7 kg. CONCLUSIONS: The present findings support the utility and interpretation of remotely assessed weight management outcomes for both research and clinical purposes. These procedures may offer greater accessibility to evidence-based measurement.

RESUMEN

OBJECTIVE: To evaluate the metabolic alterations associated with gestational diabetes mellitus (GDM) in women with overweight or obesity. RESEARCH DESIGN AND METHODS: We compared fasting and postprandial plasma glucose and free fatty acid (FFA) concentrations, insulin sensitivity (IS; Matsuda index), and ß-cell function (i.e., ß-cell responsiveness to glucose) by using a frequently sampled oral glucose tolerance test (OGTT) at 15 and 35 weeks' gestation in women with overweight or obesity who had GDM (n = 29) or did not have GDM (No-GDM; n = 164) at 35 weeks. RESULTS: At 15 weeks, IS and ß-cell function were lower, and fasting, 1-h, and total area-under-the-curve plasma glucose concentrations during the OGTT were higher (all P < 0.05) in the GDM than in the No-GDM group. At 35 weeks compared with 15 weeks, IS decreased, ß-cell function increased, and postprandial suppression of plasma FFA was blunted in both the GDM and No-GDM groups, but the decrease in IS and the increase in postprandial FFA concentration were greater and the increase in ß-cell function was less (all P ≤ 0.05) in the GDM than in the No-GDM group. A receiver operating characteristic curve analysis showed that both fasting plasma glucose and 1-h OGTT glucose concentration at 15 weeks are predictors of GDM, but the predictive power was <30%. CONCLUSIONS: Women with overweight or obesity and GDM, compared with those without GDM, have worse IS and ß-cell function early during pregnancy and a greater subsequent decline in IS and blunted increase in ß-cell function. Increased fasting and 1-h OGTT plasma glucose concentration early during pregnancy are markers of increased GDM risk, albeit with weak predictive power.

RESUMEN

BACKGROUND: General and eating disorder (ED) psychopathology are common among children and adults with overweight/obesity; few studies have examined their course of change throughout family-based behavioural obesity treatment (FBT) and maintenance. OBJECTIVES: Examine: (1) the changes in the parent and child general and ED psychopathology during FBT and maintenance interventions; (2) the associations between change in psychopathology and change in weight among children or parents; (3) the associations between change in psychopathology within parent-child dyads. METHODS: 172 parent-child dyads participated in 4-month FBT and were subsequently randomized to one of three 8-month maintenance interventions. General psychopathology (child anxiety/depressive symptoms, parent severity of global psychological distress), ED psychopathology (shape/weight concern), and percent overweight were assessed at baseline, post-FBT, and post-maintenance. Separate linear mixed-effects models evaluated change in general and ED psychopathology, including an interaction between maintenance condition and time. Partial correlations examined associations between change in psychopathology and percent overweight among children or parents, and associations between change in psychopathology within parent-child dyads. RESULTS: Among children, significant reductions were observed from baseline to post-FBT in all forms of psychopathology and from post-FBT to post-maintenance in general psychopathology. Among parents, significant reductions were observed from baseline to post-FBT in all forms of psychopathology; reductions were maintained from post-FBT to post-maintenance. There was no significant interaction between maintenance condition and time. Correlations between change in most forms of parent or child psychopathology and percent overweight were observed. CONCLUSIONS: Participation in FBT and maintenance was associated with improvements in general and ED psychopathology in both parents and children.

RESUMEN

Lifestyle therapy (energy restriction and exercise) is the cornerstone of therapy for people with type 2 diabetes (T2D) but is difficult to implement. We conducted an 8-month randomized controlled trial in persons with obesity and T2D (17 women and 1 man) to determine the therapeutic effects and potential mechanisms of intensive lifestyle therapy on cardiometabolic function. Intensive lifestyle therapy was conducted at the worksite to enhance compliance and resulted in marked (17%) weight loss and beneficial changes in body fat mass, intrahepatic triglyceride content, cardiorespiratory fitness, muscle strength, glycemic control, ß cell function, and multi-organ insulin sensitivity, which were associated with changes in muscle NAD+ biosynthesis, sirtuin signaling, and mitochondrial function and in adipose tissue remodeling. These findings demonstrate that intensive lifestyle therapy provided at the worksite has profound therapeutic clinical and physiological effects in people with T2D, which are likely mediated by specific alterations in skeletal muscle and adipose tissue biology.

RESUMEN

OBJECTIVE: Obesity increases the risk for pregnancy complications and maternal hyperglycemia. The Institute of Medicine developed guidelines for gestational weight gain (GWG) targets for women with overweight/obesity, but it is unclear whether exceeding these targets has adverse effects on maternal glucose metabolism. METHODS: Insulin sensitivity (assessed using the Matsuda Insulin Sensitivity Index), ß-cell function (assessed as insulin secretion rate in relation to plasma glucose), and plasma insulin clearance rate were evaluated using a frequently sampled oral glucose tolerance test at 15 and 35 weeks of gestation in 184 socioeconomically disadvantaged African American women with overweight/obesity. RESULTS: Insulin sensitivity decreased, whereas ß-cell function and insulin clearance increased from 15 to 35 weeks of gestation in the entire group. Compared with women who achieved the recommended GWG, excessive GWG was associated with a greater decrease in insulin sensitivity between 15 and 35 weeks. ß-cell function and plasma insulin clearance were not affected by excessive GWG. CONCLUSIONS: These data demonstrate that gaining more weight during pregnancy than recommended by the Institute of Medicine is associated with functional effects on glucose metabolism.

RESUMEN

BACKGROUND AND OBJECTIVES: Although obesity is typically associated with metabolic co-morbidities, some people with obesity do not develop metabolic abnormalities. We evaluated whether modifiable lifestyle factors (i.e., physical activity, dietary composition, and sleep characteristics) can help explain why some people with obesity are metabolically healthy (MHO) and whether metabolically unhealthy obesity (MUO) affects quality of life (QOL). SUBJECTS/METHODS: Physical activity and sleep characteristics were assessed by using tri-axial accelerometers and dietary intake, sleep quality, and QOL were evaluated by using validated questionnaires in people stratified into three groups: (1) lean with normal glucose tolerance, plasma triglyceride (TG) concentration and intrahepatic TG (IHTG) content (metabolically healthy lean [MHL]; n = 20); (2) obesity and normal glucose tolerance, plasma TG concentration and IHTG content (MHO; n = 36); and (3) obesity with abnormal glucose metabolism and hepatic steatosis (MUO; n = 43). RESULTS: People with MHO performed ~45-min more light-intensity physical activity/day than the MHL and MUO groups (P < 0.05). QOL, particularly the physical function domain, was higher in the MHO than the MUO group (P < 0.05). Although self-reported intake of starch, dairy, and cured meats were higher in the MUO than the MHO group (P < 0.02), the absolute differences were small and unlikely to have metabolic effects. No differences were found in sleep duration or quality between groups. CONCLUSIONS: These data suggest physical activity, but not sleep or dietary intake, contribute to better metabolic health in people with MHO than those with MUO, and that QOL is lower in people with MUO than those with MHO.

RESUMEN

PURPOSE: Little is known about the influence of social network support on child health behaviors in the context of weight-loss interventions. This study examined the associations between a child's co-participation (i.e., network support) in weight-related health behaviors (i.e., physical and sedentary activity, eating behavior) and the child's own health behaviors during family-based behavioral treatment (FBT). METHODS: Children (n = 241) with overweight/obesity (mean age = 9.4 ± 1.3y; 63% female) completed semi-structured interviews assessing network support for healthy/unhealthy eating and physical/sedentary activity, and a 3-day dietary recall. Physical activity was assessed with accelerometry, and sedentary activity was measured via parent-reported child screen time use. All assessments were taken at baseline and after 4 months of FBT. Hierarchical linear regressions examined changes in network support as they related to changes in health behaviors from baseline to the end of FBT. RESULTS: Changes in network support for healthy eating were related to changes in vegetable, but not fruit, intake across FBT, while changes in network support for unhealthy eating were negatively related to changes in diet quality. Changes in network support for sedentary activity were negatively related to changes in minutes of physical activity and positively related to changes in screen time. CONCLUSION: The present findings suggest that a child's network support for health behaviors may relate to behavior change among children during FBT and provide opportunities for targeted intervention. LEVEL OF EVIDENCE: III. cohort study.

RESUMEN

BACKGROUND: Family-based behavioural weight loss treatment (FBT) is an evidence-based intervention for paediatric overweight/obesity (OV/OB), but little research has examined the relative efficacy of FBT across socioeconomic status (SES), and racial groups. METHOD: A total of 172 youth (7-11 years; 61.6% female; 70.1% White, 15.7% Black; child percent OV = 64.2 ± 25.2; 14.5% low-income) completed 4 months of FBT and 8 months of additional intervention (either active social facilitation-based weight management or an education control condition). Parents reported family income, social status (Barratt simplified measure of social status) and child race at baseline. Household income was dichotomized into < or >50% of the area median family income. Race was classified into White, Black or other/multi-race. Treatment efficacy was assessed by change in child % OV (BMI % above median BMI for age and sex) and change in child BMI % of 95th percentile (BMI % of the 95th percentile of weight for age and sex). Latent change score models examined differences in weight change between 0 and 4 months, 4 and 12 months and 0 and 12 months by income, social status and race. RESULTS: Black children had, on average, less weight loss by 4 months compared to White children. Low-income was associated with less weight loss at 4 months when assessed independent of race. No differences by race, social status or income were detected from 4 to 12-months or from 0 to 12 months. CONCLUSIONS: FBT is effective at producing child weight loss across different SES and racial groups, but more work is needed to understand observed differences in initial efficacy and optimize treatment across all groups.

RESUMEN

OBJECTIVE: This study compares children with severe obesity and children with mild obesity/overweight participating in family-based obesity treatment (FBT) on change in (1) relative weight and adiposity and (2) psychosocial distress. METHODS: Children 7 to 11 years old (N = 241) and their parents participated in 12 months of behavioral treatment (FBT + maintenance treatment) and completed anthropometric, adiposity, and psychosocial assessments (psychiatric disorder symptomology, quality of life). Severe obesity was defined as a baseline BMI ≥ 120% of the 95th percentile (N = 105). RESULTS: At 12 months, 40% of children with baseline severe obesity no longer had severe obesity. Percent overweight and fat mass index measurements showed similar magnitudes of change among children with severe obesity and children with mild obesity/overweight, whereas BMI z score and percent body fat change was lower in the group with severe obesity. Youth with severe obesity were higher on some measures of psychosocial distress at baseline but generally experienced improvements similar to children with mild obesity/overweight. CONCLUSIONS: FBT with maintenance treatment is beneficial for children with severe obesity and is recommended for use prior to more invasive treatments in severe pediatric obesity. Future studies should assess the necessity of additional treatment, as children with severe obesity still have high relative weights post intervention.

RESUMEN

OBJECTIVE: This study examined patients with binge-eating disorder (BED) subtyped by dietary restraint (DR) and the negative affect (NA) dimension of depression, anxiety, hostility, and self-esteem, comparing clinical features and outcome of evidence-based psychological treatments. It was hypothesized that individuals with DR and high NA (DR-HNA) would have lower functioning and poorer immediate and long-term BED treatment outcomes compared to those with DR and low NA (DR-LNA). METHOD: Cluster analysis was conducted (n = 159) as a secondary analysis of data from a randomized group cognitive-behavioral therapy and interpersonal psychotherapy trial of women and men with BED. RESULTS: At pretreatment, participants with DR-HNA were higher in eating disorder and general psychopathology, emotional eating, and poor social adjustment. At post-treatment, differences in binge days between cluster groups were small and statistically nonsignificant, and differences in rates of binge-eating abstinence were only marginally significant. However, by 1-year follow-up, patients with DR-HNA had a greater increase in binge days, less abstinence from binge eating, a higher risk for relapse, and were significantly less likely to be in BED remission than those with DR-LNA. CONCLUSIONS: DR-HNA served as a predictor of poorer maintenance of BED therapeutic improvement. Future directions to better sustain outcomes among patients with DR-HNA include developing a brief measure to assess for the full construct of NA prior to and throughout treatment, enhancing BED interventions by focusing more on NA, and augmenting treatment dose.

RESUMEN

BACKGROUND: This study aimed to further elucidate correlated weight changes in parent-child dyads enrolled in family-based treatment (FBT) by modeling the interdependence of weight changes during treatment. METHODS: Parent-child dyads (n = 172) with overweight/obesity (child mean zBMI = 2.16 ± 0.39; parent mean BMI = 37.9 ± 9.4 kg/m2 ) completed 4 months of FBT and were randomized to one of three 8-month maintenance interventions (Social Facilitation Maintenance [SFM]-high dose, SFM-low dose or control). Weight/height was measured at 0, 4 and 12 months. Structural equation models simultaneously estimated the effect that an individual had on their own (actor effect) and on one another's (partner effect) weight-status across time using the actor-partner interdependence model. RESULTS: Actor paths were significant over time for parent and child. Partner paths were significant for child zBMI predicting parent BMI at 4 and 12 months. Maintenance condition moderated actor/partner paths in the model. CONCLUSIONS: Child weight change may motivate parents to make environmental and behavioural changes that impact their own weight.

RESUMEN

BACKGROUND: Concurrent general psychopathology (GP) and eating disorder psychopathology (EDP) are commonly reported among youth with overweight/obesity and may impact weight change. PURPOSE: We identified patterns of GP and EDP in children with overweight/obesity and examined the impact on weight change following family-based behavioral obesity treatment (FBT) and maintenance interventions. METHODS: Children (N = 172) participated in 4 month FBT and subsequent 8 month weight maintenance interventions. GP and EDP were assessed prior to FBT (baseline). Child percentage overweight was assessed at baseline, post-FBT (4 months), and post-maintenance (12 months). Latent profile analysis identified patterns of baseline GP and EDP. Linear mixed-effects models examined if profiles predicted 4- and 12-month change in percentage overweight and if there were two-way and three-way interactions among these variables, adjusting for relevant covariates. RESULTS: Results indicated a three-profile structure: lower GP and EDP (LOWER); subclinically elevated GP and EDP without loss of control (LOC; HIGHER); and subclinically elevated GP and EDP with LOC (HIGHER + LOC). Across profiles, children on average achieved clinically meaningful weight loss (i.e., ≥9 unit change in percentage overweight) from baseline to 4 month FBT and sustained these improvements at 12 month maintenance. There was no evidence that latent profiles were related to percentage overweight change from baseline to FBT (p > .05) or baseline to maintenance (p > .05). There was no evidence for two-way or three-way interactions (p > .05). CONCLUSION: Concurrent GP and EDP do not portend differential short- or long-term weight change following FBT and maintenance. Future research is warranted on the durability of weight change among youth with GP and EDP. TRIAL REGISTRATION: NCT00759746.

RESUMEN

BACKGROUND: Some studies have suggested that in people with type 2 diabetes, Roux-en-Y gastric bypass has therapeutic effects on metabolic function that are independent of weight loss. METHODS: We evaluated metabolic regulators of glucose homeostasis before and after matched (approximately 18%) weight loss induced by gastric bypass (surgery group) or diet alone (diet group) in 22 patients with obesity and diabetes. The primary outcome was the change in hepatic insulin sensitivity, assessed by infusion of insulin at low rates (stages 1 and 2 of a 3-stage hyperinsulinemic euglycemic pancreatic clamp). Secondary outcomes were changes in muscle insulin sensitivity, beta-cell function, and 24-hour plasma glucose and insulin profiles. RESULTS: Weight loss was associated with increases in mean suppression of glucose production from baseline, by 7.04 µmol per kilogram of fat-free mass per minute (95% confidence interval [CI], 4.74 to 9.33) in the diet group and by 7.02 µmol per kilogram of fat-free mass per minute (95% CI, 3.21 to 10.84) in the surgery group during clamp stage 1, and by 5.39 (95% CI, 2.44 to 8.34) and 5.37 (95% CI, 2.41 to 8.33) µmol per kilogram of fat-free mass per minute in the two groups, respectively, during clamp stage 2; there were no significant differences between the groups. Weight loss was associated with increased insulin-stimulated glucose disposal, from 30.5±15.9 to 61.6±13.0 µmol per kilogram of fat-free mass per minute in the diet group and from 29.4±12.6 to 54.5±10.4 µmol per kilogram of fat-free mass per minute in the surgery group; there was no significant difference between the groups. Weight loss increased beta-cell function (insulin secretion relative to insulin sensitivity) by 1.83 units (95% CI, 1.22 to 2.44) in the diet group and by 1.11 units (95% CI, 0.08 to 2.15) in the surgery group, with no significant difference between the groups, and it decreased the areas under the curve for 24-hour plasma glucose and insulin levels in both groups, with no significant difference between the groups. No major complications occurred in either group. CONCLUSIONS: In this study involving patients with obesity and type 2 diabetes, the metabolic benefits of gastric bypass surgery and diet were similar and were apparently related to weight loss itself, with no evident clinically important effects independent of weight loss.

RESUMEN

BACKGROUND: There is a need for workplace programs promoting healthy eating and activity that reach low-wage employees and are scalable beyond the study site. Interventions designed with dissemination in mind aim to utilize minimal resources and to fit within existing systems. Technology-based interventions have the potential to promote healthy behaviors and to be sustainable as well as scalable. We developed an interactive obesity treatment approach (iOTA), to be delivered by SMS text messaging, and therefore accessible to a broad population. The aim of this pilot study was to evaluate participant engagement with, and acceptability of, this iOTA to promote healthy eating and activity behaviors among low-wage workers with obesity. METHODS: Twenty participants (self-reporting body mass index ≥ 30 kg/m2) of a single workgroup employed by a university medical practice billing office had access to the full intervention and study measures and provided feedback on the experience. Height and weight were measured by trained research staff at baseline. Each participant was offered a quarterly session with a health coach. Measured weight and a self-administered survey, including dietary and activity behaviors, were also collected at baseline, 3, 6, 12, 18, and 24 months. Participant engagement was assessed through responsiveness to iOTA SMS text messages throughout the 24-month pilot. A survey measure was used to assess satisfaction with iOTA at 3 months. Due to the small sample size and pilot nature of the current study, we conducted descriptive analyses. Engagement, weight change, and duration remaining in coaching are presented individually for each study participant. RESULTS: The pilot was originally intended to last 3 months, but nearly all participants requested to continue; we thus continued for 24 months. Most (14/20) participants remained in coaching for 24 months. At the 3-month follow-up, eight (47%) of the remaining 17 participants had lost weight; by 24 months, five (36%) of the remaining 14 participants had lost weight (one had bariatric surgery). Participants reported very high satisfaction. CONCLUSIONS: This pilot provides important preliminary results on acceptability and participant engagement with iOTA, which has significant potential for dissemination and sustainability.

RESUMEN

To examine the communication between obstetric providers and their socioeconomically disadvantaged, African American patients who are overweight and obese during pregnancy, and whether this communication relates to outcomes. Pregnant patients and their obstetric providers were surveyed between October 2012 and March 2016 at Washington University School of Medicine in St. Louis, MO. Percent agreement between patients' and obstetric providers' survey responses was analyzed and measured (κ coefficient). Descriptive and multilevel logistic regression analyses aimed at identifying the relation of perceived communication between providers and patients to gestational weight gain, diet, and exercise during pregnancy. A total of 99 pregnant women and 18 obstetric providers participated in the study. Significant lack of agreement was observed between patients and obstetric providers regarding communication about weight gain recommendations, risk factors associated with excessive weight gain, what constitutes adequate exercise per week, exercise recommendations, dietary recommendations, and risk factors associated with a poor diet. Our findings suggest patients were not receiving intended messages from their obstetric providers. Thus, more effective patient-obstetric provider communication is needed regarding gestational weight gain, exercise and dietary recommendations among overweight/obese, socioeconomically disadvantaged, African American women.

RESUMEN

Introduction: Social support for healthy eating can influence child eating behaviors; however, little is known about the impact of social support during family-based behavioral weight-loss treatment (FBT). This study aimed to determine the impacts of both baseline and change in family support on change in child diet and weight during FBT. Methods: Children (n = 175; BMI percentile ≥85th; ages 7-11; 61.1% female; 70.9% white) and a participating parent completed 4 months of FBT. Parents were active participants and learned social support-related strategies (i.e., praise and modeling of healthy eating). Child perceived family encouragement and discouragement for healthy eating, child diet quality (via 24-hour recalls), and child weight were assessed pre- and post-FBT. Results: Family encouragement for healthy eating increased during FBT, and this increase was related to increases in child healthy vegetable intake and overall diet quality, as well as decreases in refined grains consumed. Low pre-FBT family encouragement predicted greater increases in healthy vegetable intake, greater weight reduction, and greater increases in family encouragement for healthy eating. Family discouragement for healthy eating did not change during treatment nor did it predict dietary or weight outcomes. Conclusions: FBT successfully improves family encouragement, which is associated with improvements in child diet. Furthermore, even children who began treatment with low family encouragement for healthy eating show great improvements in dietary intake and weight during treatment. Results suggest that changes in child eating behavior during treatment is influenced by active, positive parenting techniques such as praise of healthy eating rather than negative family support.

RESUMEN

BACKGROUND: Children with overweight/obesity are more likely to exhibit symptoms of depression and anxiety than are their peers without overweight/obesity; however, the rates and correlates of depression and anxiety symptoms among children seeking obesity treatment remain unclear. OBJECTIVES: Examine the prevalence and associated factors of depression and anxiety symptoms among treatment-seeking children with overweight/obesity. METHODS: Children 7 to 11 years old (N = 241) and their parents completed assessments before beginning family-based behavioral weight-loss treatment. Disorder-specific self-report questionnaires assessed child depression and anxiety. The social-ecological model served as a framework for examining factors associated with depression and anxiety symptoms. RESULTS: Among our sample, 39.8% (96/241) met clinical cutoffs for depression and/or anxiety symptomatology. Specifically, of these 96, 48 met criteria for both depression and anxiety, 24 for depression only, and 24 for anxiety only. Child eating disorder pathology, parents' use of psychological control (ie, a parenting style characterized by emotional manipulation), and lower child subjective social status were significantly associated with greater child depression symptomatology. Child eating disorder pathology and parent psychological control were significantly associated with greater child anxiety symptomatology. CONCLUSION: Nearly 40% of children exhibited psychopathology symptoms, and a variety of correlates were found. Thus, pediatric weight-loss providers may consider screening for and addressing mental health concerns (and associated factors) prior to and during treatment.

RESUMEN

OBJECTIVE: This study aimed to assess the efficacy of a home-based lifestyle intervention delivered through Parents as Teachers (PAT), a national home-visiting organization, designed to minimize excessive weight gain through 12 months post partum in socioeconomically disadvantaged (SED) African American women with overweight or obesity. METHODS: This randomized controlled trial was conducted at a single center as part of the Lifestyle Interventions for Expectant Moms (LIFE-Moms) consortium. Analysis was conducted with 185 SED African American women (BMI 25.0-45.0 kg/m2 at pregnancy onset) retained from an original sample of 267 randomized to standard PAT or PAT+Lifestyle, which embedded lifestyle therapy within standard PAT delivered prenatally and for 12 months post partum. RESULTS: Compared with standard PAT, the PAT+Lifestyle group gained less weight (2.5 kg vs. 5.7 kg; P = 0.01) and were more likely to return to their baseline weight (38.0% vs. 21.5%; P = 0.01) from baseline to 12 months post partum. There were no differences between groups in cardiometabolic outcomes, indices of glycemic control and insulin sensitivity, and plasma lipid profile. The estimated cost of PAT+Lifestyle was $81 more to deliver per family than standard PAT. CONCLUSIONS: PAT+Lifestyle decreases weight gain during pregnancy through 12 months post partum in SED African American women with overweight or obesity at the start of pregnancy with minimal additional cost.
