Exploring the health visiting service from the view of South Asian clients in England: a grounded theory study

The fact that health inequalities disproportionately affect the minority ethnic population is not new and projections are that the minority ethnic population will continue to increase. The importance of early intervention and the key role that health visitors can play in attempting to reduce health inequalities is well documented as is the requirement for health providers to establish culturally sensitive services. To date, much of the research has focused on the perspectives of healthcare professionals caring for minority ethnic clients in hospital‐based settings and little is known about the perspectives of minority ethnic clients regarding the health visiting service (HVS). The aim of this study was to explore the perspectives of South Asians regarding their experiences with the HVS. The study was conducted in a small town in the South of England between March and June 2013. A qualitative study using a grounded theory approach was used to capture the perspectives of this group regarding their interactions with the HVS. The sample consisted of 15 participants and data were collected through audio‐recorded semi‐structured interviews and analysed using constant comparative approach. Three key categories were identified: ‘understanding the health visitor's role’, ‘sensitivity of services’ and ‘the significance of family’. While clients valued one‐to‐one support from health visitors, there was some evidence of poor communication and ethnocentric tendencies within the service. It was found that South Asian clients distinguish between health and parenting advice, being more likely to accept health advice from their health visitor and more likely to accept parenting advice from their family. The findings, although limited in their generalisability, offer important insights into how South Asians perceive the service and will equip health visitors with a better understanding of how best to improve the experience of South Asian clients accessing the health visiting.     

Prevention and management of food allergy

The phenotypic expression and natural history of food allergy vary widely according to the patient's age, disease presentation and type of offending food. Prevention of food allergy might be achieved by altering the dietary factors responsible for the sensitization and phenotypic expression of the disease. Owing to the peculiarity of the atopic status, a minute amount of allergens can trigger both sensitization and symptoms in atopic individuals. The oral dose of β-lactoglobulin causing sensitization can be estimated to be between 1 ng and several milligrams. In food allergy, sensitization and treatment are allergen specific; therefore, for primary prevention (avoiding sensitization) and secondary prevention of food allergy (avoiding symptoms in an already sensitized subject), a product without immunogenic and allergenic epitopes should be given in each case. Babies of atopic parents are particularly prone to develop food allergy and for this reason they are called high-risk babies. Cow's milk is the most commonly offending food in both gastrointestinal and cutaneous manifestations. Cow's milk proteins are potent allergens and around 2.5% of infants experience cow's milk allergy in the first years of life. The major risk factors for cow's milk allergy are positive family history of atopy and early exposure to cow's milk proteins. Hydrolysate formulae have been developed for the purpose of reducing the allergenicity of cow's milk proteins. More recently, partially and extensively hydrolysed formulae have also been used for feeding babies with a high risk of atopy for the prevention of cow's milk allergy. However, according to the results of a recent randomized controlled study, only an extensively hydrolysated formula, and not a partially hydrolysated formula, significantly decreased the prevalence of cow's milk allergy.
