ObjectiveAtrial fibrillation can lead to stroke if untreated, and identifying those at higher risk is necessary for cost-effective screening for asymptomatic, paroxysmal atrial fibrillation. Age has been proposed to identify those at risk, but risk models may provide better discrimination. This study compares atrial fibrillation risk models with age for screening for atrial fibrillation.MethodsNine atrial fibrillation risk models were compared using the Atherosclerosis Risk in Communities study (11 373 subjects, 60.0±5.7 years old). A new risk model (Screening for Asymptomatic Atrial Fibrillation Events—SAAFE) was created using data collected in the Monitoring Disparities in Chronic Conditions study (3790 subjects, 58.9±15.3 years old). The primary measure was the fraction of incident atrial fibrillation subjects who should receive treatment due to a high CHA2DS2-VASc score identified when screening a fixed number equivalent to the age criterion. Secondary measures were the C statistic and net benefit.ResultsFive risk models were significantly better than age. Age identified 71 (61%) of the subjects at risk for stroke who subsequently developed atrial fibrillation, while the best risk model identified 96 (82%). The newly developed SAAFE model identified 95 (81%), primarily based on age, congestive heart failure and coronary artery disease.ConclusionsUse of a risk model increases identification of subjects at risk for atrial fibrillation. One of the best performing models (SAAFE) does not require an ECG for its application, so that it could be used instead of age as a screening criterion without adding to the cost.

Restricting dietary fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) can alleviate symptoms in children with disorders of gut-brain interaction (DGBI). Due to the restrictions of a low FODMAP diet (LFD), a less restrictive FODMAP Gentle diet (FGD) has been suggested. However, the types and amounts of high FODMAP foods and carbohydrates commonly consumed by children have not been studied. We aimed to identify the high FODMAP foods and proportions of FODMAP carbohydrates consumed by children with DGBI and healthy children (HC) and to determine which usually ingested FODMAPs would be restricted on the FGD. Three-day diet records from both children with DGBI and HC were analyzed and compared to assess the type and amount of high FODMAP foods and carbohydrates ingested. Additionally, the ingested FODMAPs that would be restricted on the FGD were determined. Diet records from 77 children with DGBI and 64 HC were analyzed. The number of foods ingested daily was similar between children with DGBI and HC (12.3 ± 4.2 vs 12.9 ± 3.4, respectively); high FODMAP foods comprised most foods eaten in both groups. Children with DGBI (vs. HC) ate fewer high FODMAP foods per day (6.5 ± 2.3 vs 8.7 ± 2.4, P < 0.0001, respectively). Fructans were the most consumed FODMAP carbohydrate in both groups, and children with DGBI (vs. HC) consumed fewer fructans, lactose, fructose, and polyols (all P < 0.0001). The top 3 food categories consumed in both groups were wheat-containing foods, dairy, and fruits/ 100% fruit juices. In children with DGBI, 80.9% of the high FODMAP foods consumed would be limited on the FGD. Children with DGBI consume fewer high FODMAP foods and carbohydrates than HC, with the top consumed FODMAP carbohydrates being fructans, lactose, and fructose. A FGD would restrict most high FODMAP foods consumed by children with DGBI.

Background Chronic pain often clusters in families, where parents and their offspring both experience chronic pain conditions. Young children of parents with irritable bowel syndrome (IBS) represent an at-risk group for the development of abdominal pain, disability, and excess health care visits in later childhood. Parental solicitous responses to children’s expressions of discomfort and maternal modeling of their own illness behavior contribute to a greater focus on somatic sensations, leading to illness behaviors in children. This randomized controlled trial will test the effectiveness of an early preventive web-based psychosocial intervention (REACH)[TM] vs. an educational web-based safety comparison condition delivered to parents with IBS to alter parental responses and lead to improved child health and decreased health care costs. Methods Parents with IBS who have children ages 4–7 years are recruited via community-based approaches (e.g., social media advertisements, school electronic distribution, research networks) and health care providers. The target sample is 460 parents randomized to REACH, a web-based social learning and cognitive behavior therapy (SLCBT) intervention or an educational web-based safety comparison condition (EC). Participants will be assessed at baseline, 6-week (immediate post-intervention), 6-month, 12-month, and 18-month follow-up periods (months post-completion of intervention). The primary outcome is change in parental solicitous/protective behaviors. Secondary outcomes include parent risk and protective factors, child health and symptom outcomes, and health care utilization and cost savings. Discussion This study adapts a validated, parent-delivered intervention to treat chronic pain in children to a web-based application designed to prevent the development of chronic pain in very young, high-risk children. If successful, this strategy can both prevent adverse sequelae of this condition from developing as well as be widely accessible. Furthermore, the availability of a prevention model for parent training could result in significant short- and long-term health benefits across a broad spectrum of conditions.

Background and Objectives: The attachment-diathesis model of chronic pain, which associates insecure attachment with pain catastrophizing and worse pain-related outcomes, is well-supported in adults. Although Functional Abdominal Pain Disorders (FAPDs) are common in youth, with symptoms influenced by the parent–child dynamic, an attachment-diathesis model of FAPDs is unexplored. The aim of this study was to investigate if insecure parental attachment is associated with pain catastrophizing and pain-related variables in youth with FAPDs. Methods: Baseline questionnaire data from an RCT of cognitive behavioral therapy for children with FAPDs (n = 200, 73% girls, 93% White, and a mean age of 11.2 years old) were used to examine relationships between parental attachment (subscales include Alienation, Trust, and Communication), catastrophizing, and pain-related variables (depression, disability, and gastrointestinal (GI) symptom severity). Results: Alienation was significantly correlated with depression (r = 0.39), GI symptom severity (r = 0.30), and disability (r = 0.22; ps < 0.05). Trust was also correlated with depression (r = −0.39), GI symptom severity (r = −0.19), and disability (r = −0.19; ps < 0.05). Communication was associated with depression (r = −0.30, p < 0.01). Catastrophizing mediated these associations, accounting for 22–89% of the relationship between attachment and pain-related variables. Conclusions: Children who report a less secure attachment to their parents report more physical and psychological symptomatology than children who describe their attachment as more secure. This association is partly explained by child catastrophizing. Results suggest that parent–child attachment and catastrophizing may be important treatment targets in children with FAPDs.

Studies testing the efficacy of behavioral interventions to modify psychosocial sequelae of inflammatory bowel disease in children are limited. This report presents outcomes through a 6-month follow-up from a large randomized controlled trial testing the efficacy of a cognitive behavioral intervention for children with inflammatory bowel disease and their parents.MethodsOne hundred eighty-five children aged 8 to 17 years with a diagnosis of Crohn's disease or ulcerative colitis and their parents were randomized to one of two 3-session conditions: (1) a social learning and cognitive behavioral therapy condition or (2) an education support condition designed to control for time and attention.ResultsThere was a significant overall treatment effect for school absences due to Crohn's disease or ulcerative colitis (P < 0.05) at 6 months after treatment. There was also a significant overall effect after treatment for child-reported quality of life (P < 0.05), parent-reported increases in adaptive child coping (P < 0.001), and reductions in parents' maladaptive responses to children's symptoms (P < 0.05). Finally, exploratory analyses indicated that for children with a higher level of flares (2 or more) prebaseline, those in social learning and cognitive behavioral therapy condition experienced a greater reduction in flares after treatment.ConclusionsThis trial suggests that a brief cognitive behavioral intervention for children with inflammatory bowel disease and their parents can result in improved child functioning and quality of life, and for some children may decrease disease activity.

Background/Objectives: Disorders of gut–brain interaction (DGBI), characterized by chronic abdominal pain and significant disability, affect 15–20% of children and adults and continue into adulthood in ~60% of cases. Costs for adults reach USD 30 billion per year, yet effective management strategies are elusive. Studies support using cognitive behavioral therapy (CBT), but abdominal pain only improves in ~40% of patients. Dietary management (low FODMAP diet; LFD) has also shown promise but it is effective in only a similar percentage of patients. Studies suggest that biologic factors (biomarkers) contribute to CBT response. Similarly, gut microbiome composition appears to influence abdominal pain response to the LFD. However, no previous CBT trials in children or adults have measured these biomarkers, and it is unclear which patients respond best to CBT vs. LFD. Methods: Children aged 7–12 years with DGBIs (n = 200) will be categorized as having/not having Autonomic Nervous System imbalance and/or abnormalities in gut physiology. We will randomize these children to either CBT or a LFD to compare the effectiveness of these treatments in those with/without abnormal physiologic biomarkers. We hypothesize that CBT will be more effective in those without abnormal physiology and LFD will be more effective in children with abnormal physiology. Primary outcome measures include the following: (1) Symptom improvement (abdominal pain frequency/severity) and (2) improvement in health-related quality of life. Conclusions: This innovative multidisciplinary study is the first to identify physiological characteristics that may moderate the response to two different management strategies. Identification of these characteristics may reduce the burden of these disorders through timely application of the intervention most likely to benefit an individual patient.

While much has been written about the relationship between only child status and parents’ behavior toward children, and consequent personality and intelligence, little is known about the relationship between only child status, parental response to illness, and subsequent child illness behavior. In this study, 227 mothers of 342 children completed measures designed to assess: (a) their children’s school attendance, (b) their own psychological status, and (c) their own responses to their children’s expressions of stomach pain. Parents of only children were more likely to minimize their children’s gastrointestinal symptoms than were parents of children with at least one sibling. In addition, only children were less likely to miss school. Parental protectiveness did not differ as a function of only child status. These findings are somewhat discrepant with commonly held beliefs about parents’ patterns of responding to only children.

Timely and accurate measurement of population protection against measles is critical for decision-making and prevention of outbreaks. However, little is known about how survey-based estimates of immunization (crude coverage) compare to the seroprevalence of antibodies (effective coverage), particularly in low-resource settings. In poor areas of Mexico and Nicaragua, we used household surveys to gather information on measles immunization from child health cards and caregiver recall. We also collected dried blood spots (DBS) from children aged 12 to 23 months to compare crude and effective coverage of measles immunization. We used survey-weighted logistic regression to identify individual, maternal, household, community, and health facility characteristics that predict gaps between crude coverage and effective coverage. We found that crude coverage was significantly higher than effective coverage (83% versus 68% in Mexico; 85% versus 50% in Nicaragua). A large proportion of children (19% in Mexico; 43% in Nicaragua) had health card documentation of measles immunization but lacked antibodies. These discrepancies varied from 0% to 100% across municipalities in each country. In multivariate analyses, card-positive children in Mexico were more likely to lack antibodies if they resided in urban areas or the jurisdiction of De Los Llanos. In contrast, card-positive children in Nicaragua were more likely to lack antibodies if they resided in rural areas or the North Atlantic region, had low weight-for-age, or attended health facilities with a greater number of refrigerators. Findings highlight that reliance on child health cards to measure population protection against measles is unwise. We call for the evaluation of immunization programs using serological methods, especially in poor areas where the cold chain is likely to be compromised. Identification of within-country variation in effective coverage of measles immunization will allow researchers and public health professionals to address challenges in current immunization programs.

Estimating vaccination coverage is challenging in resource-poor settings where accurate records are sparse. Household surveys, a key source of coverage information, typically capture data from child health cards and rely on maternal recall when cards are unavailable. As a result, little is known about how coverage estimates based on maternal recall differ from those based on health cards for the same children. Furthermore, little is known about how these measures compare with actual rates of seroconversion, which could be used to estimate effective coverage of immunisations. This study compares the accuracy of maternal recall, health card documentation, and antibody presence in vaccination coverage estimates in the state of Chiapas, Mexico. Data for this study were collected as part of the Mesoamerican Health Initiative 2015 baseline survey. A random sample of 4700 households with children under-5 and women of reproductive age were surveyed. A pre-survey census was carried out within segments that had been randomly selected with probability proportional to size. Standardised multilingual household surveys were implemented using netbooks. Anthropometric measurements were collected for all children under-5 and dry blood spot samples for the detection of measles antibodies were collected from children aged 12–23 months. Preliminary results suggest that maternal recall, child health cards, and antibody tests generate differing estimates of immunisation coverage. Recall differs from card-based estimates of vaccination coverage by up to 40 percentage points. There are potentially considerable differences in measles immunisation coverage as assessed by the presence of measles antibodies versus other survey sources, highlighting weaknesses in card accuracy, card coverage, and vaccine administration. Current national estimates of immunisation coverage based on the combination of maternal recall and children's health cards may be overestimating actual protection against vaccine-preventable diseases. Correcting for biases in recall and card coverage may produce more accurate estimates of intervention coverage.

Background Health has improved markedly in Mesoamerica, the region consisting of southern Mexico and Central America, over the past decade. Despite this progress, there remain substantial inequalities in health outcomes, access, and quality of medical care between and within countries. Poor, indigenous, and rural populations have considerably worse health indicators than national or regional averages. In an effort to address these health inequalities, the Salud Mesoamérica 2015 Initiative (SM2015), a results-based financing initiative, was established. Methods For each of the eight participating countries, health targets were set to measure the progress of improvements in maternal and child health produced by the Initiative. To establish a baseline, we conducted censuses of 90,000 households, completed 20,225 household interviews, and surveyed 479 health facilities in the poorest areas of Mesoamerica. Pairing health facility and household surveys allows us to link barriers to care and health outcomes with health system infrastructure components and quality of health services. Results Indicators varied significantly within and between countries. Anemia was most prevalent in Panama and least prevalent in Honduras. Anemia varied by age, with the highest levels observed among children aged 0 to 11 months in all settings. Belize had the highest proportion of institutional deliveries (99%), while Guatemala had the lowest (24%). The proportion of women with four antenatal care visits with a skilled attendant was highest in El Salvador (90%) and the lowest in Guatemala (20%). Availability of contraceptives also varied. The availability of condoms ranged from 83% in Nicaragua to 97% in Honduras. Oral contraceptive pills and injectable contraceptives were available in just 75% of facilities in Panama. IUDs were observed in only 21.5% of facilities surveyed in El Salvador. Conclusions These data provide a baseline of much-needed information for evidence-based action on health throughout Mesoamerica. Our baseline estimates reflect large disparities in health indicators within and between countries and will facilitate the evaluation of interventions and investments deployed in the region over the next three to five years. SM2015’s innovative monitoring and evaluation framework will allow health officials with limited resources to identify and target areas of greatest need.
