Passive smoking and health of child
There is usually no that small children smoke by oneself. In addition, there is much time when there are small children in home. When smoker is there in family living together, passive smoking (passive smoking) breathing smoke (environmental cigarette smoke: ETS: environmental tobacco smoke) of cigarettes in environment that smoker smokes in environment called home, and occurred passively becomes problem for small children.
In environmental cigarette smoke (ETS), it is said that 4000 or more kinds of chemical substances are included. We are known as material that 40 kinds or more may produce cancer in people and animal of those. In addition, it is said to triple density that it can be from double at home where smoker is in comparison with home where smoker is to nobody as for the density in air of suspended particulate matter (SPM: suspended particulate matter) which can be breathed in to the depths of the lungs with particle diameter less than 2.5 micrometers. These chemical substances or suspended particulate matter (SPM: suspended particulate matter) to produce by smoking may have various influences on health of children.
Passive smoking and lower respiratory tract flame (bronchitis, pneumonia) of child
About pneumonia, bronchitis of babies under 1, there is study that it is easy to be in pneumonia, bronchitis with double probability as for the domestic baby who smokes with parents from domestic baby who does not smoke with parents either (references 3).
There is study that checked relations with hospitalization of babies under 1 and smoking of mother (references 4). It was pneumonia, bronchitis (p <0.001) and the damage, poisoning (p <0.01) that case that mother smoked was higher in probability that babies than case that mother did not smoke under 1 were hospitalized. Probability that case that mother smoked was hospitalized with baby of 6-9 months by pneumonia, bronchitis was high at the age of the month. When mother smoked for upper respiratory tract inflammation, gastroenteritis, in case that mother did not smoke, significant difference was not seen in probability that babies under 1 were hospitalized. The winter season has much hospitalization of babies due to pneumonia, bronchitis under 1, but difference of probability of hospitalization in case that mother does not smoke grows big in the winter season when mother smokes. The winter season has less ventilation of living room than other seasons, and influence with smoke of cigarette seems to be strong, too. Probability of hospitalization of babies due to pneumonia, bronchitis under 1 was high so that there was much number that mother breathed per day.
Passive smoking of child and exudative otitis media
In children with passive smoking, it is thought that it is easy to suffer from exudative otitis media in comparison with child without passive smoking.
Passive smoking and bronchial asthma of child
When parent smokes about children of bronchial asthma, there is more frequency of attack, and it is known that symptom such as stridor, a cough, sputum, dyspnea tends to get heavier.
Passive smoking and sudden infant death syndrome of child
It is thought that revelation to environmental cigarette smoke (ETS) of infants is one of the risk factors of sudden infant death syndrome (SIDS: sudden infant death syndrome). But it is thought that smoking of mother in time of intrauterine fetus is main risk factor. It is important for the prevention to give up smoking before the pregnancy. We refer to our Yokohama City Inst. of Health homepage for "the pregnancy and smoking".
Cholesterol in passive smoking and blood of child
In children with passive smoking, HDL cholesterol (good cholesterol) was lower than child that there was not passive smoking, and, in study (references 5) for pubertal students, tendency that arteriosclerosis index (total cholesterol/HDL cholesterol) became higher was seen. Adipose conjugation of such a blood lets arteriosclerosis progress, and heart disease such as angina and myocardial infarction and the risk that it is will increase in the future.
Passive smoking and cancer of child
With people who had passive smoking in home only for the child era, it is easy to be for cancer in comparison with people whom there was not of passive smoking with people whom there was of passive smoking in home with the adult times in the child times only in the adult times, and there is study that it is hard to be for cancer in comparison with people whom there was of passive smoking with the adult times in the child times (references 2). People that there was passive smoking from people that there was not passive smoking with under 10 years old with under 10 years old seem to be easy to become leukemia.
It is ... for the prevention of adverse effects to health by passive smoking of child
Parent will know adverse effects to health that may happen by passive smoking of child. And, for children, let's stop that we smoke.
When we smoke, in the home, let's breathe outdoors not indoor. When we breathe indoors, we will ventilate well.
