Satisfaction with local healthcare services and medical need among hypertensive patients: a nationwide study.

BACKGROUND: Investigating the factors associated with unmet medical needs is important since it can reflect access to healthcare. This study examined the relationship between the unmet medical needs of patients with hypertension and their satisfaction with the healthcare services available in their neighborhoods. METHODS: Data were from the 2021 Korean Community Health Survey. The sample included individuals aged 19 years who were diagnosed with hypertension. The main outcome measure was unmet medical need. The relationship between the outcome measure and independent variables were analyzed using multivariate logistic regressions, along with a subgroup analysis based on whether patients were currently receiving treatment for hypertension. RESULTS: Unmet medical needs were found in 4.3% of the study participants. A higher likelihood of unmet medical needs was found in individuals not satisfied with the healthcare services at proximity (adjusted OR = 1.69, 95% CI: 1.49-1.92) compared to those satisfied with services nearby. Similar tendencies were found regardless of whether individuals were currently receiving treatment for hypertension, although larger differences were found between groups in participants who were currently not receiving treatment. CONCLUSIONS: The findings infer the need to consider patient satisfaction with nearby healthcare services in implementing public health policies that address unmet medical need in patients with hypertension.

Five-year Trajectory about Screening for Complication of Diabetes Kidney Disease and Cardiovascular Disease Mortality : Focusing on Regional Difference.

BACKGROUNDS: The overall screening rate for complication of diabetes kidney disease is improving; however, regional variations are increasing. It is necessary to select regions vulnerable to change and understand their characteristics. METHODS: Group-based trajectory analysis was performed to derive change patterns in the complication of diabetes kidney disease screening rate in 244 regions using Community Health Survey data between 2015 and 2019. ANOVA test was conducted to examine the differences in regional characteristics and CVD in each change pattern. RESULTS: The change patterns in complication of diabetes kidney disease screening rate were classified into four groups: high and rapidly increasing (Group 1, 5.2%), steady high (Group 2, 8.2%), moderate and increasing (Group 3, 52.9%), and low and slightly increasing (Group 4, 23.8%). Group 4 had many rural areas and worse socioeconomic status, healthcare systems, health behaviors, and diabetes management, and these regions had higher CVD mortality rates. CONCLUSIONS: Regions where the screening for complication of diabetes kidney disease rate did not improve compared to other regions were vulnerable not only in socioeconomic status, healthcare system, and health behavior, but also in disease management. This suggests the need for local and environmental support, as well as aggressive health service interventions in relatively vulnerable areas.

Area-level deprivation and handwashing behavior during the COVID-19 pandemic: A multilevel analysis on a nationwide survey in Korea.

This study investigated the association between area deprivation level and performance of handwashing behavior during the COVID-19 pandemic in Korean adults. This study used data from the 2015 Population and Housing Census data to measure area deprivation level. The 2020 Korea Community Health Survey was used for all other variables, including hand hygiene behavior (August through November 2020). The association between area deprivation level and practice of handwashing behavior was examined using multilevel logistic regression analysis. The study population comprised 215,676 adults aged 19 years or above. Compared to the least area deprived group, the most deprived group was more likely to not wash hands after using the restroom (OR 1.43, 95% CI 1.13-1.82), after coming home (OR 1.85, 95% CI 1.43-2.39), and using soap (OR 1.55, 95% CI 1.29-1.84). The findings suggest the importance of considering area deprivation in implementing policies that promote handwashing, particularly during a pandemic.

Patients with diabetes in regions with population decline and likelihood of receiving diabetes management education and screenings for related complications in Korea.

OBJECTIVE: Many municipal districts in Korea face population decline owing to overall population decreases and aging. We investigated the association between geographic rurality and likelihood of receiving diabetes management education and diabetic retinopathy and diabetes-related kidney disease screenings among adults with diabetes. METHODS: Patient data were obtained from the 2021 Korea Community Health Survey (27,391 individuals; aged ≥19 years and physician-diagnosed with diabetes mellitus). Geographic rurality was categorized based on population decline as follows: with, at risk of, or without population decline. The association between geographic rurality and likelihood of receiving diabetes management education and diabetic retinopathy and diabetes-related kidney disease screenings was examined using multilevel logistic regression analyses. RESULTS: Among 27,391 patients with diabetes, 31.1% received diabetes education; 40.0% and 46.4% were screened for diabetic retinopathy and diabetes-related kidney disease, respectively. Individuals residing in regions with population decline were less likely to receive diabetes education (odds ratio [OR] 0.62, 95% CI 0.50-0.75) and diabetic retinopathy (OR 0.79, 95% CI 0.70-0.90) and diabetes-related kidney disease (OR 0.64, 95% CI 0.55-0.75) screenings, as compared with their counterparts. CONCLUSIONS: Our findings highlight the importance of increased monitoring and providing diabetes education and screenings for patients with diabetes living in rural areas.

Public perception of the appropriateness of COVID-19 management strategies and level of disturbances in daily activities: A focus on educational level.

BACKGROUND: This study investigated the association between public perception of the appropriateness of management strategies implemented during the COVID-19 pandemic and the level of disturbances in daily activities reported by the general population. METHODS: This cross-sectional study used Korea Community Health Survey conducted from August to November 2020. Public perception of COVID-19 management strategies included those implemented by the government (central, city or provincial, and administrative districts), the mass media, regional medical institutions, and neighbors. The subjective level of disturbances in daily activities was measured using a 0-100 numeric rating scale developed by Korea Disease Control and Prevention Agency. Multivariable linear regression analysis was used. A subgroup analysis was conducted based on education level. RESULTS: The present study analyzed 211,353 participants. Compared to individuals who perceived that the management strategies implemented during the pandemic was 'highly appropriate,' those who reported 'mediocre appropriateness' (ß: -1.96, p-value: <0.001) or 'low appropriateness' (ß: -3.60, p-value: 0.010) reported higher levels of subjective disturbances. The appropriateness of measures implemented by the mass media was associated with levels of subjective disturbances felt by individuals of lower education with statistical significance, whereas that applied by the mass media and the government were important in those with higher education. CONCLUSIONS: The findings suggest the importance of public perception of management strategies when implementing containment policies and minimizing its disturbances on daily lives is essential.

Physical activity, sedentary behavior, and cardiovascular disease risk in Korea: a trajectory analysis.

OBJECTIVES: To identify the distinct trajectories of sedentary behavior (SB) and explore whether reduced cardiovascular disease (CVD) risk was associated with a distinct trajectory of physical activity (PA). METHODS: We analyzed data from 6,425 people who participated in the Korean Health Panel Survey over a period of 10 years. The participants' self-reported SB and PA were assessed annually, and trajectory groups were identified using a group-based trajectory model for longitudinal data analysis. Logistic regression analysis was performed to assess the association between CVD risk (10-year cumulative incidence) and the trajectories of SB and PA. The adjusted variables included socio-demographic factors, the predisposing diseases of CVD, and baseline health behaviors. RESULTS: Trajectory analysis identified 4 SB trajectory groups: SB group 1 (low and slightly increasing trend, 53.1%), SB group 2 (high and rapidly decreasing trend, 14.7%), SB group 3 (high and slightly decreasing trend, 9.9%), and SB group 4 (low and rapidly increasing trend, 22.2%). The 3 PA trajectory groups were PA group 1 (moderate and slightly decreasing trend, 32.1%), PA group 2 (low and slightly decreasing trend, 57.3%), and PA group 3 (maintained inactivity, 10.7%). By the 10-year follow-up, 577 cases of incident CVD had occurred. We also noted a 50% reduction in the risk of CVD when SB group 4 was accompanied by PA group 1 (odds ratio, 0.50; 95% confidence interval, 0.28 to 0.90). CONCLUSIONS: Despite increased time spent in SB, maintaining PA about 2 days to 3 days per week reduced the occurrence of CVD.

The association between night eating syndrome and health-related quality of life in Korean adults: a nationwide study.

PURPOSE: Quality of life may be influenced by the presence of eating disorders. This study investigated the association between night eating syndrome (NES) and health-related quality of life in the general population. METHODS: Data were from the 2019 Korea Community Health Survey. The presence of NES was determined using the Night Eating Questionnaire. Health-related quality of life was measured using the 3-level EuroQoL-5 Dimension Index. Multivariable linear regression analyses assessed the association between NES and health-related quality of life. Subgroup analyses were performed based on daily sleep duration. RESULTS: A total of 34,434 individuals aged 19 years or older were included in the study population. Participants with NES (ß = - 4.85, p < 0.001) reported poorer health-related quality of life scores than those without NES. Decreases in health-related quality of life scores among those with NES were greatest in those who slept over 8 h daily (ß = - 12.03, p = 0.004), followed by those who slept less than 6 h (ß = - 5.90, p = 0.006) and participants who slept between 6 and 8 h (ß = - 3.40, p = 0.026) daily. CONCLUSION: Individuals with NES were more likely to have a lower health-related quality of life than those without NES. These findings highlight the potential importance of considering NES in investigating the health-related quality of life. LEVEL OF EVIDENCE: Level III, well-designed case-control analytic studies.

Is COVID-19 induced reductions in the level of physical activity associated with increased depressive symptoms in patients with hypertension?

BACKGROUND: Studies have reported that the coronavirus 2019 (COVID-19) outbreak led to reduced levels of physical activity, but this has been rarely studied in patients with hypertension. This study investigated the association between depressive symptoms and changes in physical activity of patients with hypertension during the COVID-19 outbreak. METHODS: Data were from the Korea Community Health Survey (KCHS), conducted between August to November 2020. The KCHS is a nationwide cross-sectional survey that evaluates information on various sociodemographic, economic, and health related variables. Depressive symptoms were measured using the Patient Health Questionnaire-9. Physical activity was measured using a questionnaire inquiring whether participants experienced any changes in physical activity after the pandemic. The association between depressive symptoms and changes in physical activity level were analyzed using a multivariable logistic regression analysis. RESULTS: Out of 55,203 patients, 39.6% responded that they had experienced lower levels of physical activity due to the pandemic and showed increased likelihoods of depressive symptoms (OR 1.33, 95% CI 1.14-1.54) than individuals who responded that they had performed similar levels of physical activity. This tendency was stronger in patients that did not receive treatment for hypertension (OR 2.07, 95% CI 1.02-4.23) than those who did receive treatment with marginal significance (p-value of interaction term: 0.1241). CONCLUSIONS: Decreased levels of physical activity due to the outbreak was experienced by a noticeable proportion of patients with hypertension and was associated with increased likelihoods of depressive symptoms.

Perceived social support and depressive symptoms during the COVID-19 pandemic: A nationally-representative study.

BACKGROUND: The COVID-19 pandemic and the associated containment policies have led to negative mental health consequences in the general population. AIMS: This study investigated the association between perceived social support and depressive symptoms in Korea. METHODS: Data from the Korea Community Health Survey conducted from August to November 2020 was used for this cross-sectional study. Depressive symptoms were measured using the Patient Health Questionnaire-9 (PHQ-9) and perceived social support was assessed based on the number of contacts that participants had identified as being available in case participants needed isolation due to COVID-19 exposure. This study included the general adult populations aged 19 years and older. The relationship between the perceived social support and depressive symptoms was analyzed using multivariable liner regression analysis. Subgroup analysis was conducted based on income. RESULTS: Analysis of the data obtained from 225,453 participants indicated that PHQ-9 scores were highest in the group with 'no' perceived social support, followed by 'low', 'middle', and 'high' perceived levels of social support. Compared to individuals with 'high' perceived social support, those with 'middle' (ß: .10, p-value <.001), 'low (ß: .07, p-value .010), and 'no' (ß: .34, p-value <.001) perceived levels of social support showed poorer depression scores. The magnitude of the relationship found was particularly strong in the low-income group. CONCLUSIONS: During the COVID-19 pandemic, individuals' depression scores varied according to their perceived level of social support. Strategies that address the need of vulnerable individuals are required to reduce the potentially negative mental health consequences of the pandemic.

Is fear of COVID-19 higher in individuals residing in more deprived areas? A nationwide study.

BACKGROUND: This study investigated the association between various types of coronavirus disease 2019 (COVID-19)-related fear and the level of area deprivation in Korea. METHODS: Different types of COVID-19-related fear were examined, namely fear of infection, fear of dying from infection, fear of public criticism, fear of a family member getting infected and fear of economic loss. The level of area deprivation was measured based on the Area Deprivation Index, which was calculated based on population census data. The association between various types of COVID-19-related fear and the level of area deprivation was analyzed using multivariable logistic regression analysis. RESULTS: This study included 199 859 individuals from the 253 administrative divisions in South Korea. Findings indicated that fear was most common in individuals residing in the most deprived areas, followed by those in the mediocre and least deprived areas (fear of infection: odds ratio (OR) 1.05, 95% confidence interval (CI) 1.01-1.09; fear of dying from infection: OR 1.23, 95% CI 1.19-1.28; fear of public criticism: OR 1.20, 95% CI 1.15-1.24; fear of a family member getting infected: OR 1.12, 95% CI 1.07-1.18). CONCLUSIONS: The findings suggest the need to monitor and account for area deprivation in managing the psychological health effects of the COVID-19 crisis.

What Types of Burden Experienced by Family Caregivers of Dementia Patients Are Related to Their Life Satisfaction?

BACKGROUND: As the burdens related to dementia caregiving are vast, this study aimed to examine the relationship between life satisfaction and different types of burden reported by family caregivers of patients with dementia. METHODS: Data from the 2019 Korea Community Health Survey were used. The association between life satisfaction and caregiving burden reported by family caregivers of patients with dementia was investigated using multivariable regression analysis. These burdens resulted from social prejudice and temporal, physical, psychological, or economic reasons. Life Satisfaction was measured using the Organization for Economic Cooperation and Development Better Life Index. Subgroup analysis was performed based on the residing status of patients with dementia and the region of residence of the caregiver. RESULTS: Data of 12 617 participants were analyzed. Compared with individuals with no burden, those who reported a burden due to temporal (ß = -0.23, p = .003), psychological (ß = -0.18, p < .001), and economic (ß = -0.27, p < .001) demands showed poorer levels of life satisfaction. These tendencies were maintained in caregivers residing with patients and those providing care for institutionalized patients. Regarding the region where the caregiver lived, for those living in rural regions, burdens related to social prejudice or economical demands were associated with poor life satisfaction. CONCLUSION: Family caregivers reporting caregiving-related burdens for temporal, psychological, or economic reasons had lower life satisfaction. These findings suggest the importance of considering caregiver's different needs and conditions when implementing coping strategies when caring for individuals with dementia.

Association between Blood Glucose Control and Subjective Cognitive Decline in Korean Patients with Diabetes Aged over 50 Years.

This study aimed to investigate the association between blood glucose control and subjective cognitive decline in adult patients with diabetes. Using the 2018 data from the community health survey, we included 18,789 patients with diabetes aged ≥50 years who had complete responses recorded. Blood glucose control was the independent variable, and subjective cognitive decline was the dependent variable. Multivariable logistic regression analysis was used to analyze the association between blood glucose control and subjective cognitive decline. Multivariable logistic regression analysis showed that blood glucose control was inversely associated with subjective cognitive decline in patients with diabetes. Patients with uncontrolled blood glucose levels had higher odds of subjective cognitive decline than those with controlled blood glucose levels (odds ratio = 1.22; 95% confidence interval: 1.10, 1.34). Our findings suggest that patients with diabetes may demonstrate subjective cognitive decline if their blood glucose levels are not well-controlled.

How Do Patients Value the Benefit of Minimally Invasive Surgery in Cancer Treatment?

OBJECTIVES: Due to the increasing cost of cancer treatment, the demand for value-based healthcare is increasing. Although several value frameworks have been developed recently in the field of oncology, the nononcological benefits of minimally invasive surgery have not been addressed. This study aimed to estimate how patients value nononcological benefits in minimally invasive cancer surgery. METHODS: The value that patients placed on various benefits of cancer surgery was termed throughout the study as patient value (PV). To quantize PVs for the benefits of cancer surgery, a one-tiered analytic hierarchy process model was constructed. The model includes 6 well-known surgical outcomes, including nononcological benefits. The study participants included 303 patients with cancer and family caregivers who participated in a questionnaire survey. RESULTS: The PVs for "decreased operation time," "reduced length of hospital stay," and "improved cosmetic results" were 0.050, 0.044, and 0.045, respectively, whereas the PVs for "increased survival," "prevention of disease recurrence," and "avoidance of complications" were 0.366, 0.292, and 0.203, respectively. The PV placed on nononcological benefits from minimally invasive surgery was one-tenth (10.2%) of the total value. CONCLUSIONS: Nononcological benefits arising from minimally invasive surgery were relatively small but nonnegligible. This value should be considered in the process of developing a value framework for cancer surgery and shared decision making.

The Ability to Rest at Home During COVID-19 Symptom Manifestation and Depressive Symptoms: Evidence From Korea.

OBJECTIVE: This study investigated the association between ability to rest at home in times of coronavirus disease 2019 (COVID-19) symptom manifestation and depressive symptoms. METHODS: The 2020 Korea Community Health Survey data were used. The presence of depressive symptoms was determined using the Patient Health Questionnaire-9. The relationship between depressive symptoms and ability to rest at home was examined using logistic regression analysis. Additional analysis was performed on the reasons for the inability to stay at home. RESULTS: Depressive symptoms were more common in participants who could not rest at home if symptoms manifested (4.1%) than those who could rest at home (2.7%). Participants who could not rest at home (OR 1.53, 95% CI 1.34-1.74) were more likely to have depressive symptoms, particularly when they had to report to work (OR 1.50, 95% CI 1.30-1.74) or purchase daily necessities (OR 2.40, 95% CI 1.15-5.03). CONCLUSION: Inability to rest at home in the case of COVID-19 symptom manifestation was associated with depressive symptoms. The findings suggest the need to address the identified vulnerable groups to mitigate the mental health consequences of the pandemic.

The association between episodes of night eating and levels of depression in the general population.

OBJECTIVE: Research has suggested that a correlation may exist between depressive mood and episodes of night eating. This study aimed to examine whether having episodes of night eating was associated with increased levels of depression. METHOD: This study used data from the 2019 Korea Community Health Survey and the study population consisted of adults aged ≥19 years. Depression levels were measured using the Patient Health Questionnaire-9. We investigated the patients' general characteristics using t-tests and analysis of variance. The association between depression levels and episodes of night eating was analyzed using a multivariable linear regression analysis. Subgroup analysis was conducted based on daily sleep duration. RESULTS: We analyzed 34,358 individuals and found higher average depression scores (ß: 4.99, p < .001) in those with episodes of night eating than those without. Large effect sizes were found for differences in depression scores between participants with and without episodes of night eating. The magnitude of this increase was particularly pronounced in individuals who reported 9 or more hours of sleep per day. DISCUSSION: An association was found between levels of depression and episodes of night eating as individuals with episodes of night eating were more likely to have higher depression scores. Our findings suggest the potential need to consider night eating when addressing the mental health of the general population.

Does having various types of fear related to COVID-19 disrupt individuals' daily life?: Findings from a nationwide survey in Korea.

OBJECTIVES: Unexpected changes in daily routines caused by the coronavirus disease 2019 (COVID-19) pandemic may affect psychological health. This study investigated the association between various types of COVID-19-related fear and the subjective level of disturbance in daily activities experienced by individuals. METHODS: This cross-sectional study used the Korea Community Health Survey conducted from August through November 2020. COVID-19-related fear included fear of infection, death, public criticism, family members getting infected, and economic loss. The subjective level of disruption in daily activities was measured using a 0-100 numeric rating scale developed by the Korea Disease Control and Prevention Agency. Multivariable linear regression was used to analyze the associations between the independent and dependent variables. A subgroup analysis was performed based on income level. RESULTS: Participants who reported fear of infection (ß=-3.37, p<0.001), death (ß=-0.33, p=0.030), public criticism (ß=-1.63, p<0.001), a family member getting infected (ß=-1.03, p<0.001), and economic loss (ß=-3.52, p<0.001) experienced more disturbances in daily activities. The magnitude of this association was most significant in the lowest-income group. CONCLUSIONS: Individuals reporting COVID-19-related fear experienced higher levels of subjective disruption in daily activities.

A comprehensive study of deaths due to exposure to humidifier disinfectant in Korea: focusing on medical records, assessment of exposure to humidifier disinfectants, and causes of death.

OBJECTIVES: We aimed to determine the characteristics of the deceased victims of deaths caused by exposure to humidifier disinfectants, and present the distribution of the victims' data submitted for damage application, demographic characteristics, imaging findings, characteristics of humidifier disinfectant exposure, and distribution of the causes of death. METHODS: An integrated database of victims was established using the medical records data of 1,413 victims submitted during the application for death damage caused by exposure to humidifier disinfectants, and the demographic characteristics, medical records, imaging findings, exposure characteristics, and cause of death were examined. RESULTS: The average numbers of data submissions of each applicant for death damage were 3.0 medical use records. A total of 608 (43.0%) victims had more than one finding of acute, subacute, or chronic interstitial lung diseases. The average daily and cumulative use times of the victims were 14.40 and 24,645.81 hours, respectively, indicating greater exposure in this group than in the survivors. The humidifier disinfectants' components comprised polyhexamethylene guanidine (72.8%), chloromethylisothiazolinone/methylisothiazolinone (10.5%), other components (15.0%), and oligo-[2-(2-ethoxy)-ethoxyethyl] guanidine chloride (1.5%). The components' distribution was 67.8% for single-component use, which was higher than that in the survivors (59.8%). The distribution of the causes of death were: respiratory diseases (54.4%), neoplasms (16.8%), and circulatory diseases (6.3%). Other interstitial lung diseases (65.5%) were the most common cause of death among those who died due to respiratory diseases. CONCLUSIONS: Careful discussions of appropriate remedies should be conducted based on a comprehensive understanding of the characteristics of the deceased victims, considering their specificities and limitations.

Is time-to-treatment associated with higher mortality in Korean elderly lung cancer patients?

Lung cancer is a leading cause of cancer-related deaths in many countries, including South Korea. As treatment delays after diagnosis may correlate with survival, this study aimed to investigate the association between time-to-treatment and one-and five-year overall mortality in patients aged 60 years or above. Survival analysis using the Cox proportional hazard model were conducted after controlling for all independent variables. Of a total of 1,535 individuals who received surgical treatment due to lung cancer, 837 patients received treatment within 30 days and 698 after 30 days of initial diagnosis. Individuals who received surgical treatment after 30 days of diagnosis were more likely to die within 1-year (Hazard Ratio, HR: 1.15, 95% Confidence Interval, CI: 1.01-1.32) and 5-year (HR: 1.16, 95% CI: 1.02-1.33) compared to those who received treatment within 30 days. The increase in mortality risk with time delay persisted when applying other cut-off times, including standards at 2, 3, and 6 months. We also found that the mortality rate of lung cancer patients differs depending on age (74 years or younger), household income (<80 percentile), patient severity, and the residing region. Our findings show that time delay is an important factor that can influence the outcome of lung cancer patients, highlighting the importance of monitoring and providing appropriate and timely treatment.

Association Between Recent Experience of Childbirth and Sleep Quality in South Korean Women: Results from a Nationwide Study.

INTRODUCTION: Although women commonly report deterioration of sleep quality postpartum, this relationship has been less studied in East Asian countries. This study investigated the association between recent experience of childbirth and sleep quality in South Korean women and additionally examined how healthy practice behavior interplays in the stated relationship. METHODS: Data from the 2018 Community Health Survey were used. Sleep quality was measured using the Pittsburgh sleep quality index (PSQI). Women who responded to have given birth in the past year were categorized as having a recent experience of childbirth. The general characteristics of the study population were investigated using chi-square test. The association between the dependent and independent variables was analyzed using multivariate logistic regression analysis. RESULTS: Of a total of 41,708 study participants, 16,877 (40.5%) individuals reported poor sleep quality. Poor sleep quality was more common in women with a recent experience of childbirth (48.4%) than those without (40.0%). Compared to individuals without a recent experience of childbirth, those with such an experience were more likely to show poor sleep quality (OR 1.50, 95% CI 1.34-1.68). Such differences were reduced in individuals with a healthy lifestyle. CONCLUSION: Recent experience of childbirth was associated with higher likelihoods of poor sleep quality in women. The degree of risks found was reduced in individuals practicing a healthy lifestyle habit. The findings infer the need to monitor and address sleep-related disturbances commonly reported among postpartum women.

Association between perceived environmental pollution and poor sleep quality: results from nationwide general population sample of 162,797 people.

OBJECTIVE/BACKGROUND: Perceived environmental pollution may play a significant role in understanding environmentally induced health-related symptoms. This study aimed to determine whether perceived environmental pollution is associated with poor sleep quality. METHODS: We conducted a cross-sectional study using data from a nationwide sample of 162,797 individuals aged ≥19 years from the 2018 Korea Community Health Survey. The Pittsburgh Sleep Quality Index was used for assessing sleep quality. Five types of perceived environmental pollutants involving air, water, soil, noise, and green space were assessed. We investigate the association between perceived environmental pollution and poor sleep quality. We also investigated whether an increasing number of perceived environmental pollutants magnified the odds of poor sleep quality. RESULTS: The prevalence of poor sleep quality was 42.7% (n = 69,554), and 15.6%, 10.1%, 11.9%, 23.0%, and 11.5% reported perceived environmental pollution concerning air, water, soil, noise, and green space, respectively. A perception of air, soil, or noise pollution was significantly associated with poor sleep quality. In addition, those perceiving a greater number of environmental pollutants had significantly higher odds of poor sleep quality. Notably, this association was magnified in individuals living in rural areas. CONCLUSIONS: Perceived environmental pollution was significantly associated with poor sleep quality. Our results suggest that a more comprehensive exposure to environmental pollution may not only have a worse effect on health outcomes including sleep quality.
