Study: Reduction in smog in Southern California resulted in major improvement in Children’s Health

There has been great increase in the pollution in the Southern California which has greatly impacted the individuals of those areas and resulted in problems of respiration. According to the latest study being conducted for tracking the problems of the southern California children’s over a period of 20 years have showed that there had been significantly lower respiratory symptoms which has resulted in improved air quality.

The study has further shown that the lungs of the children have gradually grown stronger over the past 20 years due to the reduction in the pollution levels in the Los Angeles. The USC researchers have examined a health issue which will be making many of the parents anxious while pulling over at their pocketblocks.

Study of the effect over respiratory systems

For studying the respiratory symptoms, USC scientists have studied their children in eight of the California communities and have defined the bronchitis symptoms over the preceding years as a means of the daily cough for three consecutive months, congestion or phlegm which are not being related to the cold or the inflation of the mucous membranes as said by the Kiros Berhane who is a lead author and a professor of the preventive medicine at the Keck School of medicine at USC.

The particular message being passed by Professor Berhane of clean air leads to good health among the childrens should be taken seriously as it is leading to the implications over how we live and further more how more productive we become. The study is being published in the Journal American Medical Association on 12th April. The study was being conducted on 4,602 children in three cohorts which were being aged in-between 5 to 18. Children’s and their parents were from the regions which included San Dimas, Upland, Riverside, Mira Loma, Lake Elsinore, Alpine and even from Santa Maria and answered questionnaires related to their child’s health.

By following more than 2,000 children in the same locations over two decades and adjusting for age, gender, ethnicity, height, respiratory illness and other variations, the study provides stronger evidence that improved air quality by itself brings health benefits — the kind that last a lifetime for children breathing cleaner air during their critical growing years.

Application of the results and its analysis

Due to the larger variations of the pollution levels among the regions being analysed the results can be successfully applied to the other parts of the United States as well and even the other parts of the world says Berhane. Further adding that the results could also further help in the management of the asthma and overall respiratory health of the children’s.

As the bronchitis symptoms are also being quite significant among the children’s which is about four times higher in the children having asthma, scientists also examined the effect of the air pollution over the same. The analysis was being adjusted based on the age, gender, race or ethnicity, second hand tobacco smoke and even the presence of cockroaches in homes.

Bronchitis and Asthma: Relation with the pollution levels

From the study it was being significant that the reduction in the bronchitis symptoms were being larger in the children’s having asthma, but were still significant in the children’s which were without asthma as well. It indicated that children’s were being benefited by the reduction of the air pollution over the past 20 years. The study has found 47 percent reduction in the tiny particulate matter from 1992 to 2011. The researchers were quite able to effectively associate the effect of the reduced pollution levels with the improved children’s healths.

Children’s which were having asthma were being 32 percent less likely to suffer from bronchitis symptoms and the children’s without the asthma experienced 21 percent reduction in their respiratory problems. The presence of nitrogen dioxide which can reduce the resistance to the infections related to the respiratory also reduced by 49 percent over the same two decades. USC researchers linked this decline with 21 percent decrease in the bronchitis symptoms in children’s with asthma and 16 percent decline in children’s without the asthma. This data is being significantly important for the further policy making and how clinicians advices, says Berhane.

The problems being related to the asthma and bronchitis is being severely affecting the overall productivity of the child and also their parents. Being in sick condition they have to also arrange the care taker for the same. Beyond quality of life it also affected children’s school attendance, parental productivity and even the society in general. Asthma is one of the common disease causing such problems in general and the reduction of 16 to 32 percent in the same is one of the great deal of achievement in terms of the overall productivity.

Effect of the strict policies over the pollution levels

California has consistently topped in the American Lung’s Association annual list of being the most polluted cities by means of ozone or the particulate matter pollution. Due to the substantial and adverse policies being put into place it has shown considerable reduction in the amount of the pollution levels of the region. Though there are quite substantial chances of improvement over the same. For quite many years environmental epidemiologists have reported the adverse health effects being caused due to the adverse pollution levels of the region. Reduction of this pollution levels will be helping in considerable improvement in the children’s health which is one of the welcome stage.

Adding to the same Berhane says that, “But we must not get complacent. We expect more cars on the road, more ships at our ports and more economic activities in the region. Even if we maintain the current policies and practices in environmental protection, pollution levels could start to rise again because of more cars and economic activities. We have to stay vigilant so that we do not lose current gains in air quality and the associated improvements in our children’s health.”

USC is being striving for conducting a research which could be applicable globally. The study being conducted is being supported by National Institute of Environmental Health Sciences, the Health Effects Institute and even the California Air Resources Board.
