Renovation, pollution, family, sleep, affect mental health

Does the decoration pollution cause harm to human health, will it have an adverse effect on people's psychology? The Provincial Center for Disease Control and the School of Public Health of Nanjing Medical University conducted a survey to provide self-assessment of 90 symptoms of “Derogatis” to more than 200 households without telling the decoration pollution. It was found that indoor air pollution may be One of the factors affecting residents' mental health

Background: The first time to explore the "pollution room" mentality

More than 80% of a person's life is spent indoors, and the quality of indoor air is closely related to the health of the body. In Nanjing, monitoring air quality after renovation has become a “compulsory course” for many decoration families. The decoration has an impact on human health. Most people know that, then, does indoor air pollution in the decoration have an impact on adult mental health?

Professor Tang Shaowen from the School of Public Health of Nanjing Medical University told the reporter that the Provincial Center for Disease Control and Prevention has carried out research on this subject. They have selected 224 households who have completed residential decoration in the past five years registered by the Nanjing Residential Decoration Management Office, and their main families are adults. Residents conduct inquiry surveys. The 224 households have reserved and tested indoor formaldehyde and total volatile organic compounds. Tang Shaowen said that in order to avoid "psychological shadows", they did not tell the family test results when conducting the survey, and then used a symptom self-rating scale to measure mental health to investigate their psychological status.

According to reports, this symptom self-rating scale includes factors that reflect somatization, obsessive-compulsive symptoms, interpersonal relationships, depressive symptoms, anxiety symptoms, hostile emotions, horror symptoms, paranoid symptoms, psychosis, eating and sleeping, etc., including 90 symptoms, the severity of each symptom is divided into 5 levels from 1 (no symptoms) to 5 (very severe). It is generally prescribed that any of the nine factors or the total score ≥ 3 is classified as “positive”, indicating that there is a moderate or higher mental health problem, and the higher the score, the lower the mental health level.

Result 1: Decoration pollution causes difficulty in falling asleep

After the psychological test was completed, the investigators compared the results of the decoration pollution test. At this time, some interesting situations were “suddenly on paper”, and then through statistical analysis and research, the problem was naturally exposed. Tang Shaowen told reporters that because this research is carried out for the first time, many details need to be studied in detail.

It is understood that the indoor air monitoring results show that in the 224 households tested, the formaldehyde exceeded 93 (41.5%), the total volatile organic compounds exceeded the standard 11 households (4.9%), and 1 households both exceeded the standard. The survey results show that the number of positive items is significantly lower than the domestic “normal”. Among them, 9 factors were divided between 1.27 and 7.71, while the domestic norm was between 1.23-1.65. Among all the factors, the average scores of the three factors including somatization, obsessive-compulsive symptoms and anxiety symptoms were higher than the national norm. .

Tang Shaowen told reporters that it may be coincidence, perhaps inevitable connection. In the decoration of polluted families, family members choose to have the first and second unhealthy factors of “difficult to fall asleep” and “inexplicable tension” among all the testing items. Bit.

Outcome 2: Women score higher than men

A survey of 158 adults over 103 adults showed that the abnormality rate of the abnormal items ranked in the top four factors, followed by somatization, obsessive-compulsive symptoms, depressive symptoms and anxiety symptoms.

In addition, according to the gender analysis of the survey subjects, the scores of male factors were lower than that of females, and the differences were statistically significant in terms of somatization, obsessive-compulsive symptoms, depressive symptoms, and anxiety symptoms. When the male and female groups are compared with the national norm, there are also differences in somatization, obsessive-compulsive symptoms, depressive symptoms, and anxiety symptoms.

Tang Shaowen told reporters that the results showed that the average scores of male factors were lower than those of females. This shows that the psychological health of female respondents in Nanjing is lower than that of males, and this may be that during the renovation period, women are The time spent in polluting indoors is more relevant.

Reminder: Beware of "bad construction syndrome"

Experts say that perhaps everyone is fully aware of the health hazards caused by serious indoor air pollution. When you have an "early warning" of skin tingling, tearing, etc., you must know that the house you have just renovated is polluted. However, if the psychological abnormality, many people simply do not know that this is also the decoration pollution in the "work".

The results of this survey showed that the scores of all factors in the households with excessive pollutants were higher than those in non-standard households, and the difference in the number of positive items was statistically significant. It was found that indoor air pollution also had a certain impact on the mental health of the population.

Tang Shaowen said that although the inevitable relationship between the two needs further investigation, on the one hand, indoor air pollution will cause various "bad construction syndromes" in the human body, which will lead to mental health problems for individuals; Neurotoxic agents, their early and low-dose effects can be manifested as changes in neurological and psychological behaviors. Organic solvent mixtures also have a certain impact on the mental state of workers. Therefore, indoor air pollution will have a certain impact on residents' mental health.
