What are the beliefs of pediatricians and dietitians regarding complementary food introduction to prevent allergy?

ABSTRACT: BACKGROUND: The timing of complementary food introduction is controversial. Providing information on the timing of dietary introduction is crucial to the primary prevention of food allergy. The American Academy of Pediatrics offers dietary recommendations that were updated in 2008. OBJECTIVE: Identify the recommendations that general pediatricians and registered dietitians provide to parents and delineate any differences in counselling. METHODS: A 9-item survey was distributed to pediatricians and dietitians online and by mail. Information on practitioner type, gender, length of practice and specific recommendations regarding complementary food introduction and exposure was collected. RESULTS: 181 surveys were returned with a 54% response rate from pediatricians. It was not possible to calculate a meaningful dietitian response rate due to overlapping email databases. 52.5% of all respondents were pediatricians and 45.9% were dietitians. The majority of pediatricians and dietitians advise mothers that peanut abstinence during pregnancy and lactation is unnecessary. Dietitians were more likely to counsel mothers to breastfeed their infants to prevent development of atopic dermatitis than pediatricians. Hydrolyzed formulas for infants at risk of developing allergy were the top choice of formula amongst both practitioners. For food allergy prevention, pediatricians were more likely to recommend delayed introduction of peanut and egg, while most dietitians recommended no delay in allergenic food introduction. CONCLUSIONS: In the prophylaxis of food allergy, pediatricians are less aware than dietitians of the current recommendation that there is no benefit in delaying allergenic food introduction beyond 4 to 6 months. More dietitians than pediatricians believe that breastfeeding decreases the risk of atopic dermatitis. Practitioners may benefit from increased awareness of current guidelines.

Project description:Food allergy is an emerging clinical condition in pediatrics, so recommendations on its management have been widely published. Studying pediatricians' adherence to these clinical practice guidelines (CPG) and understanding the reasons for their non-compliance can help to promote better management of this condition. A cross-sectional study was conducted by a survey among Brazilian pediatricians, randomly selected during the 38th Brazilian Congress of Pediatrics, which took place in October, 2017. A validated questionnaire with 16 questions addressing knowledge and practice on food allergy, as well as self-reported adherence to international guidelines was applied. Of the total of 415 pediatricians from all regions of the country who were surveyed, only 69 (16.7%) had a satisfactory adherence rate (?80%). Adequate adherence to the guidelines was associated with the variables: 'evaluating more than 10 children with suspected cow's milk allergy (CMA) per month'; 'having read the Brazilian consensus'; or 'being aware of any international food allergy guideline'. In 8 of the 10 questions that assessed conscious adherence, a minority of those surveyed (20.3-42.3% variation) stated that they knew that their response was in line with the guidelines. This finding was statistically significant (p<0.05) in 7 of these 8 questions. The self-reported adherence of Brazilian pediatricians to international food allergy guidelines was low. Pediatricians who evaluated a higher number of children with suspected CMA or who were aware of the recommendations, had a higher rate of adherence. The results of the survey found that lack of resource was the major reported barrier to guideline adherence but lack of awareness must be a relevant non perceived barrier. This study shows the pediatricians´ self-reported adherence to food allergy guidelines in a widely overview for the first time in Brazil. More studies are necessary to investigate adherence to guidelines by pediatricians in other countries and to develop strategies to improve adherence.

Project description:ImportanceThe American Academy of Pediatrics and the Centers for Disease Control and Prevention recommend waiting 3 to 5 days between the introduction of new complementary foods (solid foods introduced to infants <12 months of age), yet with advances in the understanding of infant food diversity, the guidance that pediatric practitioners are providing to parents is unclear.ObjectiveTo characterize pediatric practitioner recommendations regarding complementary food introduction and waiting periods between introducing new foods.Design, setting, and participantsIn this survey study, a 23-item electronic survey on complementary food introduction among infants was administered to pediatric health care professionals from February 1 to April 30, 2019. Responses were described among the total sample and compared among subgroups. Survey invitations were emailed to 2215 members of the Illinois Chapter of the American Academy of Pediatrics and the national American Academy of Pediatrics' Council on Early Childhood. Participants were required to be primary medical practitioners, such as physicians, resident physicians, or nurse practitioners, providing pediatric care to infants 12 months or younger.Main outcomes and measuresThe main outcome measures were recommendations on age of complementary food introduction and waiting periods between the introduction of new foods. Categorical survey items were reported as numbers (percentages) and 95% CIs. Means (SDs) were used to describe continuous survey items.ResultsThe survey was sent to 2215 practitioners and completed by 604 (response rate, 27.3%). Of these respondents, 41 were excluded because they did not provide care for infants or pediatric patients. The final analyses included responses from 563 surveys. Of these, 454 pediatricians (80.6%), 85 resident physicians (15.1%), and 20 nurse practitioners (3.6%) completed the survey. Only 217 practitioners (38.6%; 95% CI, 34.1%-44.6%) recommended waiting 3 days or longer between food introduction; 259 practitioners (66.3%; 95% CI, 61.4%-70.8%) recommended waiting that amount of time for infants at risk for food allergy development (P = .02). A total of 264 practitioners (46.9%; 95% CI, 42.8%-51.0%) recommended infant cereal as the first food, and 226 practitioners (40.1%; 95% CI, 36.1%-44.2%) did not recommend a specific order. A total of 268 practitioners (47.6%; 95% CI, 43.5%-51.7%) recommended food introduction at 6 months for exclusively breastfed (EBF) infants, and 193 (34.3%; 95% CI, 30.5%-38.3%) recommended food introduction at 6 months for non-EBF infants (P < .001); 179 practitioners (31.8%; 95% CI, 28.1%-35.8%) recommended food introduction at 4 months for EBF infants, and 239 practitioners (42.5%; 95% CI, 38.4%-46.6%) recommended food introduction at 4 months for non-EBF infants (P < .001). A need for additional training on complementary food introduction was reported by 310 practitioners (55.1%; 95% CI, 50.9%-59.1%).Conclusions and relevanceIn this survey study, most pediatric practitioners did not counsel families to wait 3 days or longer between introducing foods unless infants were at risk for food allergy development. The findings suggest that the current recommendation limits infant food diversity and may delay early peanut introduction. Because the approach to food allergy prevention has changed, a reevaluation of published feeding guidelines may be necessary.

Project description:BackgroundHousehold endotoxin levels have been variably associated with risk for asthma and atopy.MethodsWe studied participants from the 2005-2006 National Health and Nutrition Examination Survey (NHANES, n = 6963), a large cohort representative of the US population (aged 1-84 years). We built logistic regression models to test for associations between house dust endotoxin and sensitization to specific foods (milk, egg, and peanut). To experimentally explore the detected epidemiologic associations, peripheral blood mononuclear cells (PBMCs) were collected from 21 children (aged 1-19 years) mono-food allergic (ie, sensitized and clinically reactive) to milk, egg, or peanut and nonallergic controls for stimulation with endotoxin and secreted cytokine measurement. For each food allergy, linear mixed-effects models were built to test the association between endotoxin stimulation and cytokine level.ResultsAmong NHANES subjects, the geometric mean household endotoxin level was 15.5 EU/mg (GSE 0.5). Prevalence of food allergen sensitization (sIgE ≥ 0.35 kUA /L) varied by food: milk 5.7%, egg 4.0%, and peanut 7.9%. In models adjusted for potential confounders (age, race, country of birth, total people per household, US region, and history of wheezing in the past year), household endotoxin level was associated with sensitization to milk (OR 1.7, 95% CI 1.2-2.1) and egg (OR 1.4, 95% CI 1.01-1.9), but not peanut (OR 0.98, 95% CI 0.8-1.2). Interferon-γ levels of endotoxin-stimulated PBMCs from children allergic to milk or egg, but not peanut, were significantly lower compared to controls in linear mixed-effects models adjusted for repeated measures, experimental variables, age, and inter-individual variability (P-values .007, .018, and .058, respectively).ConclusionHigher household endotoxin is associated with increased odds of milk and egg sensitization. Altered cytokine responsiveness to endotoxin is also observed in PBMCs from individuals with milk and egg allergy.

Project description:BackgroundThe influences of breastfeeding and infant diet in the prevention of allergy-related diseases are uncertain and many of the studies conducted on the topic are limited by methodological challenges. Our aim was to assess whether the duration of breastfeeding and age at complementary food introduction affected the prevalence of asthma, wheeze, allergic rhinoconjunctivitis (ARC) and eczema at two and six years of age.MethodsWe used information gathered between 2000 and 2014 through questionnaires in the Prevention of Allergy among Children in Trondheim (PACT) study, a prospective cohort study in Trondheim, Norway. The current study includes 6802 children who submitted questionnaires detailing breastfeeding duration and or age at introduction to complementary foods, as well as at least one of the child health questionnaires completed at two and six years of age. Adjusted odds ratios (aORs) were calculated for each combination of exposure and outcomes and sensitivity analyses were performed to assess the possible influence of recall bias and reverse causality.ResultsThe mean duration of breastfeeding was 11 months (SD 5.6) in this study population and 5695 of 6796 (84%) infants had been breastfed for at least 6 months. We did not find any conclusive preventative effect of longer breastfeeding on parental reported doctor-diagnosed asthma, aOR 0.79 (95% CI 0.51, 1.21). However, at 6 years of age we observed a reduction in the less strictly defined outcome wheeze, aOR 0.71 (95% CI 0.53, 0.95). Longer breastfeeding was associated with a reduced risk of ARC at 2 years, aOR 0.65 (95% CI 0.49, 0.86), with a continued protective trend at 6 years, aOR 0.77 (95% CI 0.58, 1.04).ConclusionsLonger breastfeeding resulted in a reduced risk of wheeze and a trend towards a protective effect on ARC up until school age. No conclusive associations were seen between the duration of breastfeeding or age at introduction to complementary foods and prevention of asthma, wheeze, ARC and eczema.Trial registrationThe trial is registered in Current Controlled Trials as ISRCTN28090297 .

Project description:IntroductionPharmacists are uniquely positioned to provide patients with evidence-based information in order to ensure effective and safe use of Complementary and alternative medicine (CAM) products.ObjectiveAssess beliefs, practices and knowledge related to CAM products among community pharmacists in Lebanon.Design, methods and settingUsing stratified random sampling, a nationally representative survey was conducted among community pharmacists in Lebanon. Through face-to-face interviews, pharmacists completed a multicomponent questionnaire consisting of four sections: (1) sociodemographic characteristics; (2) beliefs related to regulation of CAM products, role of media in promoting their safe use, availability of resources and continuing education; (3) practices including selling CAM products, providing advice for patients and reporting adverse effects and (4) knowledge about specific CAM products, their uses, side effects and interactions.ResultsA total of 341 pharmacists agreed to participate (response rate: 86%). Only pharmacists with complete data were included in this study (n=310). Pharmacists agreed that CAM products are effective (63.8%) and that they should be exclusively sold in pharmacies (80.3%), but disagreed that commercially marketed CAM products are well regulated (63.5%) and that media plays a positive role in educating users about these products (55.8%). As for practices, 64.5% of pharmacists were always or often advising patients on safe use; however, 74.2% of participants rarely or never reported adverse effects. Regarding knowledge, although the majority of pharmacists were aware of the uses of CAM products, fewer knew about their side effects and their interactions with drugs. After adjustment for covariates, receiving education/training on CAM products during university was the sole predictor of higher knowledge score (ß=0.68, 95% CI 0.29 to 1.07).ConclusionsThis study revealed positive beliefs of pharmacists in Lebanon towards CAM products and indicated important gaps in their practice and knowledge. Deliberate efforts to enhance the education of pharmacists are warranted to ensure the safe integration and use of CAM products in Lebanon.
