Chronic disease self-management within the monthly benefit cycle of the Supplemental Nutrition Assistance Program.

OBJECTIVE: The present study explored chronic disease management over the monthly benefit cycle among primary food shoppers from households receiving Supplemental Nutrition Assistance Program (SNAP) benefits in Philadelphia, PA, USA. DESIGN: In-depth interviews, participant observation and surveys were conducted with the primary food shopper of SNAP households. SETTING: Interviews and surveys were conducted in a clinical setting at Children's Hospital of Philadelphia, at participants' homes, and in food procurement settings including grocery stores, food pantries and soup kitchens. PARTICIPANTS: Eighteen adults who received SNAP; five with a diet-related chronic condition, five managing the chronic condition of a family member and thirteen with overweight or obesity. RESULTS: All households had at least one member with a chronic disease or condition. Households reported that the dietary demands of managing chronic illnesses were expensive and mentally taxing. Food and financial shortfalls at the end of the benefit cycle, as well as reliance on charitable food assistance programmes, often had negative impacts on chronic disease self-management. CONCLUSIONS: Drawing from nearly 50 h of in-depth qualitative interviews with SNAP participants, the study highlights the dual cognitive burden of poverty and chronic disease and elucidates the particular challenges of food procurement and maintenance of diet quality throughout the benefit month faced by SNAP households with diet-related chronic diseases. Interventions targeted at reducing the cost of medically appropriate, healthy foods may help to improve chronic disease self-management within SNAP populations.

Energy Balance and Mechanisms of Weight Gain with Ivacaftor Treatment of Cystic Fibrosis Gating Mutations.

OBJECTIVE: To determine if ivacaftor treatment results in weight gain and improved pulmonary function in people with cystic fibrosis transmembrane conductance regulator gating mutations. STUDY DESIGN: Children and adults with cystic fibrosis and at least 1 cystic fibrosis transmembrane conductance regulator gating mutation were evaluated in this observational study before and after 3 months of ivacaftor treatment. Body size and composition, total energy expenditure, resting energy expenditure (REE%) as percent predicted, coefficient of fat absorption (CFA%), fecal calprotectin, fecal elastase, and quality of life were assessed. Some outcomes were explored by pancreatic status. RESULTS: There were 23 patients (5-61 years of age) who completed the study; 70% had pancreatic insufficiency (PI). Patients gained 2.5 ± 2.2 kg (P < .001) with increased (P < .05) fat-free mass (0.9 ± 1.9 kg) and fat mass (1.6 ± 1.5 kg). REE% decreased by 5.5 ± 12.0% (P < .05), fecal calprotectin decreased by 30 ± 40 µg/g stool (P < .01), and total energy expenditure was unchanged. Improvements were greater for PI than patients who were pancreatic-sufficient. CFA% increased significantly only with PI. The change (Δ) in weight was positively correlated with the percent change in forced expiratory volume at 1 second (r = 0.46; P = .028) and ΔCFA% (r = 0.47; P = .032) and negatively with ΔREE% (r = -0.50; P = .017). Together, ΔREE%, ΔCFA%, and the percent change in forced expiratory volume at 1 second explained 58% of the variance in weight gain (adjusted R2 = 0.579; P = .0007). Growth status and muscle strength improved, as did quality of life in several domains. Fecal elastase increased in most patients with pancreatic sufficiency, with no change in those with PI. CONCLUSIONS: Mechanisms identified for ivacaftor-associated weight gain were decreased REE, gut inflammation, and fat malabsorption (CFA). TRIAL REGISTRATION: ClinicalTrials.gov: NCT02141464.

Acceptance of a meal kit programme in an outpatient paediatric weight management clinic: A qualitative pilot study.

Lack of food preparation knowledge, time to prepare meals and concerns about fruit and vegetable spoilage before consumption are the potential barriers to home cooking. These barriers may be addressed by meal kits (bundles of recipes and ingredients). We described home cooking barriers and evaluated acceptability of meal kits, using semi-structured focus groups with caregivers and adolescent patients of an outpatient paediatric weight management clinic. One meal kit per family, containing non-perishable food, a $20 gift card to a grocery store and recipes designed by clinic dietician for two meals, were given at clinic appointments. Two in-person semi-structured focus groups were conducted within 2 weeks of meal kit receipt. Four adolescent participants (75% female; 12.7 ± 0.9 years) and eight caregivers (88% female) participated in the focus groups. Four barriers to home cooking were identified: (a) healthy food cost, (b) preparation time, (c) food preparation knowledge and (d) picky eaters. Participants felt the meal kits addressed the time and lack of food preparation knowledge barriers to home cooking. A clinical meal kit programme was acceptable to a treatment-seeking adolescent population with obesity and their caregivers.

Associations between paediatric fatigue and eating behaviours.

BACKGROUND: In adults, poor sleep quality is associated with increased obesogenic eating behaviours; less is known about this relationship in youth. The objectives of this study were to assess the strength of association between fatigue-related quality of life (QoL) and eating behaviours among youth and to describe the associations in participants with percent body fat (%BF) above and below the 90th percentile for sex and age. METHODS: Caregiver-reported measures of fatigue (Pediatric QoL Multidimensional Fatigue Scale) and eating behaviours (Child Eating Behaviour Questionnaire) were obtained from participants aged 8-17 years. %BF was measured by iDXA and grouped by sex- and age-specific percentiles. Multiple linear regression adjusting for age, sex and race/ethnicity was used. RESULTS: Of the 352 participants (49% male), 44.6% had %BF >90th percentile. General, sleep/rest and cognitive fatigue QoL was inversely associated with food approach behaviours: food responsiveness, enjoyment of food, emotional overeating and desire to drink. For participants with %BF >90th percentile, higher general fatigue QoL was associated with higher satiety responsiveness (0.13; 95% confidence interval [CI 0.03, 0.24]). For participants with %BF ≤90th percentile, higher general fatigue QoL was associated with less satiety responsiveness (-0.16; 95% CI [-0.31, -0.01]). CONCLUSION: Less fatigue symptoms were associated with less behaviours associated with food approach among paediatric participants. For participants with %BF >90th percentile, less symptoms of general fatigues corresponded with more satiety. Though causation has yet to be established, youth with elevated %BF should be screened for fatigue symptoms and offered counselling on sleep hygiene or a sleep medicine referral to help mitigate weight gain.

Food and financial coping strategies during the monthly Supplemental Nutrition Assistance Program cycle.

One in seven Americans participates in the Supplemental Nutrition Assistance Program (SNAP), making it the largest federally funded food assistance program. SNAP benefits are distributed once per month and both food spending and calorie consumption tend to decrease as time from benefit distribution increases. The monthly SNAP benefit cycle has serious implications for the health and financial stability of low-income families, a growing number of whom rely on SNAP as their sole source of income. Relatively little is known about the specific coping strategies households use to manage the SNAP cycle. The purpose of this study is to provide a critical exploration of the nature and timing of coping strategies for managing the SNAP cycle, including implications these coping mechanisms have for health and financial stability. This paper presents data from a prospective cohort study of mothers (n = 12) receiving SNAP benefits in Philadelphia between 2016 and 17. Both in-depth qualitative and survey methods were used. Participants reported on a variety of coping strategies they used to manage the SNAP cycle, including adjustments to shopping and eating patterns, mental accounting, emotional resilience, and social support. Instrumental social support was particularly vital in the final days of the benefit cycle, as were skipping meals and purchasing less expensive, energy-dense foods. Constant vigilance was required throughout the month to manage financial instability. The coping strategies for managing the SNAP cycle have short-term benefits, such as buffering against hunger and financial instability, however these survival strategies may have negative long-term repercussions for physical and financial health.

Cardiovascular Risks and Benefits of Medications Used for Weight Loss.

Obesity is a complex disease influenced by many neurohormonal pathways which regulate body weight toward homeostasis. Presently, the disease of obesity effects over a billion individuals worldwide with scalable treatment options in dire need. Pharmacologic interventions for obesity have been developed to help promote weight loss in individuals with obesity. This area is rapidly developing and will only exponentially increase to serve the demand for persons with obesity seeking biologically orientated solutions to treat their disease. Therefore, understanding the cardiovascular risks and benefits of these weight loss medications is of particularly importance due to obesities strong association with cardiovascular (CV) disease risk. Moreover, past experiences with pharmacotherapy agents with weight loss properties have demonstrated an association with adverse CV outcomes, leading to market removal, in most cases and concerns over using similar medications. To better understand the CV risks and benefits pharmacotherapy agents used for weight loss, this review will discuss medications which are FDA-approved for weight loss, as well as medications commonly used off-label for this indication. The goal is to provide an overview of the risks and benefits many of these medications can offer to help guide clinical decision making and patient education.

Relationships among Child Eating Behaviors and Household Food Insecurity in Youth with Obesity.

Background: Food insecurity may trigger eating behaviors that contribute to pediatric obesity. The aim of this study is to identify eating behaviors among a pediatric population with obesity and household food insecurity. Methods: A cross-sectional study analyzed Child Eating Behavior Questionnaire (CEBQ) and household food insecurity screener responses, and BMI measurements from pediatric participants with obesity (BMI ≥95th percentile) from a weight management clinic between 2013 and 2017. Multivariate linear regression was performed to evaluate associations between CEBQ eating domains [Food Responsiveness, Emotional Overeating, Enjoyment of Food, Desire to Drink (DD), Satiety Responsiveness, Slowness in Eating, Emotional Undereating (EUE), and Food Fussiness] and household food insecurity, adjusting for age, sex, race/ethnicity, SNAP participation, and BMI percentile. A sub-group analysis was performed on participants from food insecure (FI) households to evaluate the associations between SNAP participation and eating domains. Results: Eight hundred twenty-two participants were included in the final analysis. Participants from FI households had significantly higher BMI percentiles even after adjustment for age, sex, race/ethnicity, and SNAP status (p = 0.000). Household food insecurity was associated with increased DD beverages (p = 0.000). Among participants from FI households, SNAP participation was significantly positively associated with the EUE (p = 0.009). Conclusions: Youth from FI households have higher BMIs even among a population with obesity. DD is positively associated with household food insecurity and may contribute to obesity in this population. Results suggest that providers treating pediatric patients with obesity should consider regularly screening for household food insecurity and associated eating behaviors as part of their medical management of obesity.

Precision medicine in adult and pediatric obesity: a clinical perspective.

It remains largely unknown as to why some individuals experience substantial weight loss with obesity interventions, while others receiving these same interventions do not. Person-specific characteristics likely play a significant role in this heterogeneity in treatment response. The practice of precision medicine accounts for an individual's genes, environment, and lifestyle when deciding upon treatment type and intensity in order to optimize benefit and minimize risk. In this review, we first discuss biopsychosocial determinants of obesity, as understanding the complexity of this disease is necessary for appreciating how difficult it is to develop individualized treatment plans. Next, we present literature on person-specific characteristics associated with, and predictive of, weight loss response to various obesity treatments including lifestyle modification, pharmacotherapy, metabolic and bariatric surgery, and medical devices. Finally, we discuss important gaps in our understanding of the causes of obesity in relation to the suboptimal treatment outcomes in certain patients, and offer solutions that may lead to the development of more effective and targeted obesity therapies.

Severe Obesity in the Pediatric Population: Current Concepts in Clinical Care.

PURPOSE OF REVIEW: This review describes (1) the clinical assessment of pediatric patients with severe obesity, including a summary of salient biological, psychological, and social factors that may be contributing to the patient's obesity and (2) the current state of treatment strategies for pediatric severe obesity, including lifestyle modification therapy, pharmacotherapy, and metabolic and bariatric surgery. RECENT FINDINGS: Lifestyle modification therapy alone is insufficient for achieving clinically significant BMI reduction for most youth with severe obesity and metabolic and bariatric surgery, though effective and durable, is not a scalable treatment strategy. Pharmacological agents in the pipeline may 1 day fill this gap in treatment. Treatment of severe pediatric obesity requires a chronic care management approach utilizing multidisciplinary teams of health care providers and multi-pronged therapies.

Treatment of Pre-pubertal Patients with Growth Hormone Deficiency: Patterns in Growth Hormone Dosage and Insulin-like Growth Factor-I Z-scores.

OBJECTIVE: To describe the range of insulin-like growth factor-I (IGF-I) z-score values (IGF-Iz) and growth hormone (GH) dose adjustments in pre-pubertal patients with GH deficiency (GHD) treated with GH in a single tertiary care center. METHODS: This is a retrospective review of GH-treated patients of ages ≤9 years with GHD, seen in an endocrinology clinic in 2013-2014. Patient demographics and pre-treatment anthropometrics, GH treatment duration, IGF-Iz, and GH dosage (mg/kg/week) were extracted. Multipredictor linear regression was used to evaluate the associations between IGF-Iz and GH dosage and subject gender, race, insurance type, age, and clinical characteristics. Logistic regression was used to calculate the odds ratio of direction of GH dose adjustment (decrease/no change versus increase) and IGF-Iz category based on patient clinical characteristics, accounting for provider random effect. RESULTS: Forty-one percent (57/139) of IGF-Iz were outside the "normal" range of between -2 and +2 standard deviation; the majority of IGF-Iz beyond the "normal" range (93%) were supraphysiologic [>+2 standard deviation score (SDS)]. Of the IGF-Iz >+2, 10/53 (18%) were followed by a GH dose increase and 30/53 (57%) had no dose change. Patient clinical characteristics and demographics did not significantly increase the odds of being in the IGF-Iz >+2 SDS category or having a dose increase in multipredictor logistic regression models. CONCLUSION: GH dosages and IGF-Iz varied, without significant patient clinical predictors. IGF-Iz was frequently supraphysiologic, and these levels often did not prompt a reduction in GH dose, likely influenced by a variety of factors. Our study emphasizes the need for better understanding of long-term safety and efficacy of maintaining supraphysiologic levels of IGF-Iz.
