To the Editor—We have previously reviewed a number of issues and challenges associated with in-flight medical emergencies.1 Recently, during a short flight from Hong Kong to Kaohsiung, one author (KLH) encountered a male passenger who summoned the flight attendants for medicine as he was having stomach cramps. The flight attendants rightly enquired about his history of drug allergy. Both antacids and paracetamol were available but only one should be offered; the man opted to take the paracetamol, and he seemed to feel better within a few minutes of taking it.
The man claimed that his stomach pain was triggered by eating and he was fine when empty-stomached. He denied any consumption of alcohol, tobacco, or over-the-counter medications. He claimed that the pain recurred approximately every month, but he had not seen any doctor about it. The author took this opportunity to provide health promotion education, noting the possibility of peptic ulcer disease and helicobacter infection, and recommending him to consult a doctor to follow up on the issue. The male passenger and his female companion appeared to be mistrustful at first but were at the end grateful for the health advice provided.
This episode exposed one of the fundamental health issues among Hong Kong citizens: living in a ‘sub-health’ state without seeking medical advice.2 This phenomenon is often due to people having a fear of doctors, antibiotics, steroids, or Western medicine.3 4 A sub-health state is characterised by some disturbances in psychological behaviours or physical characteristics, or in some indices of medical examination, with no typical pathologic features.5 A survey conducted by The University of Hong Kong in 2013 revealed that 97% of the surveyed Hong Kong citizens have experienced at least one sub-health symptom, and the most affected were aged 30 to 49 years, with an average of more than nine symptoms each.2 The impact should not be underestimated as 64% of the respondents reported that their daily lives were adversely affected.2
Public health promotion should target this sub-health state population, to prevent the potential development of chronic diseases. Health authorities should consider validated questionnaires to measure sub-health status in the primary care setting, so that interventions can be provided before it is too late.6
