Flashcards in Lifestyle factors and respiratory disease Deck (15)
The common cold and its effects
It is the most common URI, caused by over 200 viruses.
Has a very massive economic impact on society.
UTIs account for 50% of all acute illnesses- major cause of morbidity and mortality.
Being cold and developing the cold
There isn't a simple cause-effect link between them.
Could be because reflex vasoconstriction in nose and upper airways inhibits respiratory defence.
Sleep and developing the cold
Sleep quality may be an important predictor of immunity.
Sleep duration and efficiency may affect development of a cold.
Vitamin C (megadose) and its effects on the cold:
Does not reduce incidence significantly in the general public- but it does in those who are under a lot of physical stress (i.e athletes)
In prophylaxis for cold duration it decreased significantly in child and adults.
Did not decrease significantly for therapy.
Effects of echinacea and the cold:
Prophylaxis and incidence
Prophylaxis and duration
Showed 10-20% reduction in incidence in pooled results but not individual trials.
No significant effect on the duration of the cold.
Stress and risk of the common cold
Chronic stress linked with developing cold (stress >1 month)
Especially interpersonal stress.
Chronic stress AND smoking increases risk of developing a cold significantly.
Lack of exercise
Sociability and risk of developing colds
Low sociability saw increase in development of cold.
Those of higher Socioeconomic class have less prevalence of colds.
- Poorer sleep and health behaviours seen in those with lower SES
Hand washing and the risk of respiratory infections
Reduces risk respiratory infections.
Increase in usage of other interventions like alcohol gel dispensers also decreases incidence.
Physical aspects that influence the onset of asthma
Demographic factors that influence the onset of asthma
Age- seen in younger people.
Sex- more common in men
SES- more common in lower SES
Young maternal age
Lifestyle factors that influence the asthmatic onset and episodes
Maternal smoking during pregnancy.
Smoking at home
Violence at home.
Physical factors that influence asthmatic episoders
Psychosocial factors in asthma
Asthma symptoms exacerbated by stress- since stress affects immune system, this may be the correlation.
Underlying RTI can be exacerbated by acute stress and cause asthma.
Dysregulation of cortisol response to stress may be important in chronic asthma.
Anxiety disorders= worse asthma symptoms
Asthmatics are not good at monitoring minor symptoms.
