The population base of food allergies is large, and severe allergic reactions caused by food allergies can even be life-threatening.
researchers recently looked at trends in hospitalization rates for people with food allergies in the UK over the past 20 years.
researchers collected data on hospitalizations for allergic reactions and deaths in the UK (England, Scotland, Wales and Northern Ireland) from 1998 to 2018, as well as prescription data for epinephrine auto-injection devices.
of the study were time trends, age and gender distribution of hospitalizations for allergic reactions caused by food and non-food, and case deaths.
between 1998 and 2018, 101,891 people were admitted to hospital with allergic reactions, of which 30,700 (30.1%) were food-induced.
The hospitalization rate for people with food allergies increased from an average of 1.23 cases per 100,000 people per year in 1998 to 4.04 cases per year in 2018, an increase of 5.7 per cent per year, with the fastest increase in hospitalizations among children under 15 years of age, from an average of 2.1 per 100,000 population per year to 9.2 (an annual growth rate of 6.6 per cent).
, the annual growth rate for 15-59-year-olds is 5.9 per cent and for those aged 60 and over 2.1 per cent.
confirmed 152 deaths in fatal incidents that may have been caused by food-induced allergic reactions.
the mortality rate for confirmed fatal food allergies fell from 0.7 per cent to 0.19 per cent (rate 0.931) and for suspected fatal food allergies from 0.9 per cent to 0.30 per cent (0.970).
46% of deaths (86 deaths, 35 of them in 1992-98) were caused by peanut or tree nut allergies.
17 (26 per cent) of the 66 school-age children died from milk allergies.
the study period, prescriptions for epinephrine auto-injection devices increased by 336 per cent (estimated ratio was 1.113; an increase of 11 per cent per year).
study found that between 1998 and 2018, there was an increase in hospital admissions for food-related allergic reactions in the UK, but a decrease in the number of deaths.
in school-age children, milk allergies are the single most common cause of fatal allergic reactions.
