Burden of dust storms on years of life lost in Seoul, South Korea: A distributed lag analysis
2022
Jung, Jiyun | Yi, Ŭn-mi | Myung, Woojae | Kim, Hyekyeong | Kim, Ho | Lee, Hyewon
Although dust storms have been associated with adverse health outcomes, studies on the burden of dust storms on deaths are limited. As global warming has induced significant climate changes in recent decades, which have accelerated desertification worldwide, it is necessary to evaluate the burden of dust storm-induced premature mortality using a critical measure of disease burden, such as the years of life lost (YLL). The YLL attributable to dust storms have not been examined to date. This study investigated the association between Asian dust storms (ADS) and the YLL in Seoul, South Korea, during 2002–2013. We conducted a time-series study using a generalized additive model assuming a Gaussian distribution and applied a distributed lag model with a maximum lag of 5 days to investigate the delayed and cumulative effects of ADS on the YLL. We also conducted stratified analyses using the cause of death (respiratory and cardiovascular diseases) and sociodemographic status (sex, age, education level, occupation, and marital status). During the study period, 108 ADS events occurred, and the average daily YLL was 1511 years due to non-accidental causes. The cumulative ADS exposure over the 6-day lag period was associated with a significant increase of 104.7 (95% CI, 31.0–178.5 years) and 34.4 years (4.0–64.7 years) in the YLL due to non-accidental causes and cardiovascular mortality, respectively. Sociodemographic analyses revealed associations between ADS exposure and the YLL in males, both <65 and ≥ 65 years old, those with middle-level education, and the unemployed, unmarried, and widowed (26.5–83.8 years). This study provides new evidence suggesting that exposure to dust storms significantly increases the YLL. Our findings suggest that dust storms are a critical environmental risk affecting premature mortality. These results could contribute to the establishment of public health policies aimed at managing dust storm exposure and reducing premature deaths.

Triclosan (TCS) is widely applied in personal care products (PCPs) as an antimicrobial preservative. Due to its toxicity and potential risk to human health, TCS has attracted mounting concerns in recent years. However, biomonitoring of TCS in large human populations remains limited in China. In this study, 1163 adults in South China were recruited and urinary TCS concentrations were determined. TCS was detected in 99.5% of urine samples, indicating broad exposure in the study population. Urinary concentrations of TCS ranged from below the limit of detection (LOD) to 270 μg/L, with a median value of 3.67 μg/L. Urinary TCS concentrations from individuals were all lower than the Biomonitoring Equivalents reference dose, suggesting relatively low health risk in the participants. TCS concentrations did not differ significantly between sexes or education levels (p > 0.05). Nevertheless, marital status and age were found to be positively influence TCS levels (p < 0.001). After adjustment for body mass index (BMI), age was determined to be positively associated with TCS concentrations (p < 0.05), particularly in the age group from 31 to 51 years old. This study provides a baseline of urinary TCS exposure in South China general adult populations.

In light of the outbreak caused by the COVID-19 and its impact on the physical and mental wellbeing, we explored the consequences of this pandemic on the mental health among pre-professional health sciences students and their awareness regarding the virus. A descriptive observational cross-sectional study was conducted at King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) in Jeddah and Riyadh campuses. Data was collected from 770 participants using an online questionnaire, and statistical analysis was performed using SPSS. The majority of the participants (87.5%) considered governmental authorities as their main source of information, and therefore, they were up to date on the general information regarding COVID-19. For findings on mental health, it was found that 61.9% were exhibiting variant degrees of depression, as well as 50% expressing signs of extremely severe anxiety. However, 50.9% of the participants expressed no signs of stress during this pandemic. An association was found between gender and mental health showing females to have higher tendencies to express signs of extremely severe depression, anxiety, and stress. An association was also found between parents’ marital status and anxiety. Analysis revealed that participants with separated parents were the least among the participants to show no signs of anxiety, as well as reporting the highest numbers in the “extremely severe” anxiety category. With the increased awareness and higher than normal levels of the investigated mental illnesses, we advise that proper action should be considered to address this issue.

Study was conducted utilizing a confirmed medication adherence scale to measure the socio-demographic profile, self-care, and medication adherence among Type-2 Diabetes Mellitus (T2DM) patients. The Fisher exact test was used to calculate the level of significance (P) using SPSS (Statistical Package for Social Sciences) Version 21.0. The research presented in this paper uses statistical evidence to assess the numerous aspects that may be linked to medication adherence. A prospective observational study was undertaken on participants visiting the outpatient department for 6 months at a North Indian tertiary care hospital to investigate the pattern and quality of life associated with T2DM. The study examined those who had T2DM for more than 2 years. At the time of the visit, subjects were interviewed using socio demographic information and a structured verified questionnaire. Fisher exact test was used to identify the parameters that were linked to medication adherence, with P0.05 being regarded statistically significant. A total of 350 T2DM outpatients were followed up on, with a male-to-female ratio of 1:0.95. A 13-item medication adherence scale was created and tested, revealing that approximately 32% of participants demonstrated high adherence to anti-diabetic drugs (score = 13). The P value was obtained using Fisher exact test for educational status, occupation, marital status, and the quantity and kind of anti-diabetic drugs was found to be 0.05. Only 32% of the respondents took their diabetes medication as prescribed, indicating the need to improve adherence among T2DM patients. The quantity and kind of anti-diabetic drugs, as well as the patients’ educational status, occupation, and marital status, all demonstrated a statistically significant relationship with medication adherence.

Yang, Menghua | Chen, Hong | Long, Ruyin | Wang, Yujie | Hou, Congmei | Liu, Bei
The promotion and use of green products is an important way to improve the living environment and reduce resource consumption and waste. Green products often have higher prices than general products due to its green attributes. According to the signal theory, purchasing green products can effectively convey the pro-social signals of the consumers. Therefore, based on the price premium characteristics of green products, this study constructed a theoretical and quantitative research model of the public’s WTP (willingness to pay) a price premium for green products and conducted an in-depth study on the consumers’ acceptability of premium for green products. A total of 991 valid questionnaires were analyzed, and the following results were obtained: (1) The public’s WTP a price premium for green products was generally low, with only 30.1% of respondents. (2) The influencing factors of the WTP a price premium for green products were conditional value>green value>functional value>value expression form>price importance. Economic factors were still the main reason that hinders the public’s WTP a price premium for green products. When the premium conveys public’s pro-social and pro-environmental signal characteristics, it could effectively improve the public’s acceptability of premium for green products. (3) The public’s WTP a price premium for green products varied with marital status, education level, working years, monthly income, and occupation characteristics. The public who were married, had a master’s degree or above, and had worked for 1 year or less and whose disposable monthly income was more than 50,000 yuan and whose occupation was engineers and technicians had the highest WTP a price premium for green products. (4) Policy guidance and media publicity had a positive moderating effect on the path of influencing factors on the WTP for green products. On this basis, this study proposes to deepen the exemplary leading role of the government and attach importance to the education and publicity function of green consumption consciousness. Enterprises should give full play to the influence of reference groups, highlight the value of green products, and popularize green products through appropriate price discount activities, so as to promote the public to participate more actively in the purchase of green products. At the same time, it can also provide reference and enlightenment for the formulation of relevant policies.

Alcohol and tobacco use are risky factors that are associated with one another. High alcohol and tobacco use are significant public health problems with social and economic costs and one of the leading causes of preventable death and disease. The aim of this study was to determine the sociodemographic and economic factors on alcohol and tobacco concurrent use. In this study, a bivariate probit model was employed to determine the factors affecting alcohol and tobacco concurrent use among individuals aged 15 and above who were living in Turkey. The data used in this study was obtained from the Turkey Health Survey conducted in 2010, 2012, 2014, and 2016 by the Turkish Statistical Institute. The data were gathered from a total of 77,327 individuals. Empirical findings suggest that factors affecting alcohol and tobacco use were simultaneous. Also, the results revealed that several key variables such as age, gender, educational status, marital status, household monthly income level, and survey year were significant determinants of alcohol and tobacco concurrent use. Psychosocial support is significant for only tobacco use. In the last decade, a number of restrictions aimed to combat alcohol and tobacco use have been associated with reducing the usage habits of individuals. This is the first study that simultaneously compared both alcohol use and tobacco use using a Turkish sample.

2022
Agbenyo, Wonder | Jiang, Yuansheng | Ntim-Amo, Gideon
Risk is associated with every sector of an economy, and the pervasiveness of risk in agriculture is not new to farmers; they have, over the decades, developed ways to minimize and cope with it. The question is whether traditional strategies employed by farmers are adequate to curb unavoidable natural disasters. This study aims to see how crop insurance affects cocoa producers’ incomes in Ghana. A well-structured questionnaire was delivered to a sample of 600 cocoa farmers in Ghana’s Ashanti region, and data was collected using a multi-stage random sampling technique. Tobit and propensity score matching effect estimators were used to examine crop insurance’s impact on cocoa farmers’ income. We found that the age of a cocoa farmer has a negative effect on the farmer’s income and is statistically significant. Our result also shows that the marital status of cocoa farmers has a significant positive impact on their income. The relationship between savings and farmers’ income was positive in our estimation. It indicates that an increase in savings attitude leads to a higher income for the farmers. The result indicates that crop insurance had a significant positive impact on cocoa farmers’ income in the Ashanti region. The study recommends that the government of Ghana, with urgency, design agricultural insurance policy that can capture various farmers in the country to enhance their income and reduce poverty. Again, insurers need to promote publicity through public seminars, training, and media advertising to improve farmer awareness and knowledge of the insurance scheme.

We aimed to estimate the non-accidental and cause-specific mortality burden attributed to diurnal temperature range (DTR) and the relative contributions of low, high, and extremely low and extremely high DTR in Yunnan, southwest China. Furthermore, we explored the possible effect modification of the DTR–mortality association by season, sex, age, ethnicity, marital status, and occupation. A standard time-series quasi-Poisson regression model combined with a distributed lag nonlinear model was used to derive estimates of city-specific DTR–mortality associations, then random effects meta-analysis was used to pool the estimated city-specific overall cumulative DTR–mortality association, estimating empirical confidence intervals (eCIs). The overall fraction of non-accidental mortality caused by DTR was 11.00% (95% eCI 3.40–17.28): high DTR accounted for most of burden (total estimate 10.03%, 95% eCI 2.59–16.32). The estimated mortality risk attributable to DTR was significantly associated with cardiovascular and respiratory mortality, with attributable fractions of 13.61% (95% eCI 3.91–21.13) and 14.32% (95% eCI 0.47–21.44), respectively. The estimated risk attributable to DTR was slightly greater for males, people ≥75 years old, married people, and non-farmers than their corresponding categories. Most of the DTR-related mortality burden was attributable to high DTR, and the mortality risk attributable to DTR might be modified by specific causes, sex, age, marital status, and occupation.

A number of studies has pointed to air pollution as an additional factor that could be associated with preterm birth. We assessed in this study the association between exposure to PM₂.₅ in ambient air during pregnancy and preterm birth in metropolitan areas of the state of Georgia, where the rate of preterm birth has been among the highest in the nation over the years. Birth data were obtained from the National Center for Health Statistics natality dataset. The study population consisted of 53,094 singleton live births between January 1 and December 31, 2004 in nine metropolitan counties of Georgia. Preterm birth was defined as birth, which occurs before 37 weeks of gestation. County-level daily air quality index (AQI) data obtained from the US Environmental Protection Agency (EPA) was used to estimate individual exposure levels of PM₂.₅ for each study participant based on the county of residence for the duration of the pregnancy. A multivariate logistic regression analysis was conducted to assess the association, adjusting for potential confounders. Of the infants whose mothers resided in the nine metropolitan counties of Georgia, 4543 (8.6%) were born preterm. A higher rate of preterm birth (9.8%) was observed in infants whose mothers were exposed to ambient PM₂.₅ with AQI values > 50 than the ones with AQI ≤ 50 (EPA standard for good air quality conditions). Mothers with exposure to PM₂.₅ at average AQI values greater than 50 during the entire pregnancy were at increased risk of preterm birth (odds ratio 1.15; 95% CI 1.07, 1.25), after adjusting for sex of infant, mother’s age, race/ethnicity, education, marital status, prenatal care, cigarette smoking, alcohol consumption, and season of conception. The study provides more evidence on the role of PM₂.₅ in preterm birth. Reducing exposure to ambient particulate matter, especially in urban areas, for pregnant women would be necessary to improve the health of infants.

2017
Rauf, Sara | Khuda Bakhsh, | Abbas, Azhar | Hassan, Sarfraz | Ali, Asghar | Kächele, Harald
Heat waves threaten human health given the fast changing climatic scenarios in the recent past. Adaptation to heat waves would take place when people perceive their impacts based on their knowledge. The present study examines perception level and its determinants resulting in adaptation to heat waves in Pakistan. The study used cross-sectional data from urban and peri-urban respondents of Faisalabad District. The study employs a health belief model to assess risk perception among the respondents. Logistic model is used to determine factors affecting level of knowledge, perception and adaptation to heat waves. Around 30% of peri-urban respondents have a low level of knowledge about the fatal impacts of heat waves. Risk perception of heat waves is very low among urban (57%) and peri-urban (66%) respondents. Households’ knowledge on heat waves is significantly related to age, gender, education, wealth and access to health services. Determinants of perception include knowledge of heat waves, age and joint effect of marital status and knowledge while income level, family size, urban/peri-urban background, perceived barriers, perceived benefits and cues to action significantly affect adaptation to heat waves. To reduce deadly health impacts, mass awareness campaigns are needed to build perception and improve adaptation to heat waves.
