Validation of the food allergy quality of life:parental burden questionnaire in the UK
Purpose - Food allergy can have a profound effect on quality of life (QoL) of the family. The Food Allergy Quality of Life—Parental Burden Questionnaire (FAQL-PB) was developed on a US sample to assess the QoL of parents with food allergic children. The aim of this study was to examine the reliability and validity of the FAQL-PB in a UK sample and to assess the effect of asking about parental burden in the last week compared with parental burden in general, with no time limit for recall given. Methods - A total of 1,200 parents who had at least one child with food allergy were sent the FAQL-PB and the Child Health Questionnaire (CHQ-PF50); of whom only 63 % responded. Results - Factor analysis of the FAQL-PB revealed two factors: limitations on life and emotional distress. The total scale and the two sub-scales had high internal reliability (all a > 0.85). There were small to moderate but significant correlations between total FAQL-PB scores and health and parental impact measures on the CHQ-PF50 (p < 0.01). Significantly greater parental burden was reported for the no-time limited compared with the time-limited version (p < 0.01). Conclusions - The FAQL-PB is a reliable and valid measure for use in the UK. The scale could be used in clinic to assess the physical and emotional quality of life in addition to the impact on total quality of life
Multimorbidity Patterns in the Elderly: A New Approach of Disease Clustering Identifies Complex Interrelations between Chronic Conditions
Objective: Multimorbidity is a common problem in the elderly that is significantly associated with higher mortality, increased disability and functional decline. Information about interactions of chronic diseases can help to facilitate diagnosis, amend prevention and enhance the patients ’ quality of life. The aim of this study was to increase the knowledge of specific processes of multimorbidity in an unselected elderly population by identifying patterns of statistically significantly associated comorbidity. Methods: Multimorbidity patterns were identified by exploratory tetrachoric factor analysis based on claims data of 63,104 males and 86,176 females in the age group 65+. Analyses were based on 46 diagnosis groups incorporating all ICD-10 diagnoses of chronic diseases with a prevalence $ 1%. Both genders were analyzed separately. Persons were assigned to multimorbidity patterns if they had at least three diagnosis groups with a factor loading of 0.25 on the corresponding pattern. Results: Three multimorbidity patterns were found: 1) cardiovascular/metabolic disorders [prevalence female: 30%; male: 39%], 2) anxiety/depression/somatoform disorders and pain [34%; 22%], and 3) neuropsychiatric disorders [6%; 0.8%]. The sampling adequacy was meritorious (Kaiser-Meyer-Olkin measure: 0.85 and 0.84, respectively) and the factors explained a large part of the variance (cumulative percent: 78 % and 75%, respectively). The patterns were largely age-dependent an

Beliefs about food allergies in adolescents aged 11–19 years: a systematic review
Aims: Research suggests of people with food allergy (FA), adolescents have the highest risk of fatal allergic reactions to food, yet understanding of this population and how they manage their condition is limited. Understanding beliefs and how they affect behaviour could inform ways to reduce risk taking behaviour and fatal reactions in adolescents. This systematic review aimed to explore beliefs adolescents hold about their FA, and how these may be associated with FA management. Demographics: Adolescents aged 11–19 years with FA. Methodology: A systematic search of seven databases was conducted. Papers of any design were included that reported on the beliefs about FA in adolescents aged 11–19 years. Data was systemised by narrative thematic analysis. Findings: 20 studies were included. Themes included navigating FA in different environments, carriage and use of adrenaline auto-injectors, management of the risk of anaphylaxis, behaviour and understanding of others, and food-allergic identity. Implications: Adolescents with FA hold a variety of condition beliefs; some beliefs were related to behaviour that could lead to an allergic reaction, while other beliefs were related to protective behaviours. Further research into understanding adolescent beliefs in order to inform clinical management and reduce the risk of potential fatal reactions is essential

Development and validation of the Anaphylaxis Quality of Life Scale for Adults
Background Anaphylaxis is a severe and potentially life-threatening allergic reaction which can have a detrimental impact on quality of life (QoL). There are no validated scales to measure the impact of anaphylaxis on QoL of adults. Objective The aim of this study was to develop and assess the reliability and validity of a QoL scale for adults with anaphylaxis (A-QoL-Adults). Methods All participants were recruited from a specialist allergy clinic and had a confirmed diagnosis of anaphylaxis (as per the WAO diagnostic criteria) to food, drugs, venom, latex or had spontaneous anaphylaxis. Interviews were conducted with 13 adults; data was analysed using thematic analysis to extract items for a QoL scale. A prototype QoL scale was then completed by 115 participants alongside validated scales to measure generic QoL (WHOQoL BREF), anxiety and depression (HADS) and stress (PSS). Results The A-QoL-Adults scale has 21-items demonstrating excellent internal reliability (Cronbach’s alpha=0.96). Factor analysis produced 3 sub-scales: Emotional Impact; Social Impact; Limitations on Life. Each have excellent internal reliability (0.92; 0.92; 0.91 respectively). Poorer anaphylaxis-related QoL (total A-QoL-Adults score and sub-scale scores) correlated significantly with poorer general QoL and greater anxiety, depression and stress (all

Food Allergy and Quality of Life:What Have We Learned?
<p>Health-related quality of life (HRQL) has become an emerging focus of interest in food allergy. Food allergy is a disease characterized by low mortality and symptoms which only occur during an allergic reaction. However, food-allergic patients continuously need to be alert when eating in order to prevent potentially severe allergic reactions, which may be fatal. Fear of such reactions and the need to be continuously vigilant may seriously compromise their HRQL. During the last decade, numerous studies have been published on food allergy and HRQL. The development of reliable, valid and responsive instruments for measuring HRQL in food allergic patients has facilitated this research even further. Such instruments have given insight into the specific problems a patient may face and the impact of food allergy-related interventions from the patient's perspective. This paper focuses on the most significant findings regarding this topic since its first appearance in the literature in 2000.</p>
