The Relationship of Social Capital and Psychological Capital with the Organizational Performance of the Staff at Jiroft University of Medical Sciences

Background: The main goal of all organizations is to improve organizational performance and achieve development and excellence. The most important factor contributing to this goal is the cohesion of social capital. The stability or cohesion of the social capital is achieved through a positive psychological state. As medical universities play a vital role in the health system, they always need development, dynamism, and optimization of organizational performance. To this end, the present study sought to investigate the relationship of social capital and psychological capital with organizational performance at Jiroft University of Medical Sciences. Methods: The data in this descriptive-analytical cross-sectional study were collected using the questionnaires developed by Felício et al and Luthans et al. The participants (n=250) were selected from the staff working at Jiroft University of Medical Sciences using multi-stage random cluster sampling and the Cochran formula. Data were analyzed using Anderson and Gerbin’s two-step approach. Results: The data revealed that psychological capital had a significant positive relationship with social capital and organizational performance. Moreover, social capital had a significant, positive, and incremental relationship with organizational performance. In addition, psychological capital had an indirect and incremental relationship with organizational performance through social capital. In other words, psychological capital indirectly improves organizational performance by increasing social capital. Conclusion: The findings from the present study suggested that psychological capital had a significant positive effect on social capital, confirming the mediating role of social capital in the relationship between psychological capital and organizational performance.

Prevalence and associated factors of myopia among adolescents aged 12–15 in Shandong Province, China: a cross-sectional study

Myopia is a growing concern worldwide, especially among adolescents. This study aimed to investigate the prevalence and associated factors of myopia in adolescents aged 12–15 in Shandong Province, China. This cross-sectional study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines and involved stratified random cluster sampling of 128,678 students from 186 middle schools across 17 cities in Shandong Province. Data collection was conducted from March to April 2024. We excluded students with organic eye diseases, abnormal binocular vision functions, or a history of eye injuries or surgeries. Myopia was assessed using the standard logarithmic visual acuity chart and autorefractor without inducing ciliary muscle paralysis. A comprehensive questionnaire survey was conducted to gather demographic characteristics and daily life behaviors. With the chi-squared test for univariable analysis and multivariable logistic regression for identifying significant factors. This study included 126,375 participants, with a gender distribution of 51.02% male and 48.98% female. The overall prevalence of myopia was 71.34%. Higher prevalence was observed in girls (72.26%) compared to boys (70.45%), and the prevalence increased with age, peaking at 73.12% in 15-year-olds. Urban residents had a higher prevalence (71.86%) than rural (70.39%). Factors such as increased frequency of eye usage while lying down or leaning forward, frequent use of eyes while walking or riding in a car, prolonged screen time, and extended homework duration were associated with higher odds of developing myopia. Conversely, higher frequency of outdoor exercise, maintaining proper posture during reading and writing, greater distance from eyes to screen, and longer sleep duration were associated with lower odds. Additionally, female gender, older age, urban residence, and parental history of myopia increased the risk. The high prevalence of myopia among adolescents in Shandong Province was influenced by a combination of demographic, behavioral, and environmental factors. The study highlighted the importance of lifestyle modifications, such as increasing outdoor activities and maintaining proper visual habits, limiting the duration of screen exposure and homework sessions, and extending sleep duration, to mitigate the risk of developing myopia. These findings underscored the need for targeted public health interventions and educational campaigns to address this significant public health issue.

The Association Between Proneness to Smartphone Addiction and Social Anxiety Among School Students and the Mediating Role of Social Support: A Call to Advance Jordanian Adolescents' Mental Health.

Social anxiety is an emerging public health issue associated with significant impairment of social functioning during adolescence. Among many determinants of social anxiety, proneness to smartphone addiction may significantly contribute to the development of social anxiety. To cope with the consequential development of social anxiety, adolescent school students may rely on various forms of social support. Particularly in the Middle East, including Jordan, the relationship between proneness to smartphone addiction and adolescent social anxiety is understudied. To examine the mediating role of social support in the relationship between proneness to smartphone addiction and social anxiety in a sample of adolescent school students. In this cross-sectional study, 432 adolescents were recruited via a random cluster sample from public schools across three provinces in Jordan. The data were collected face-to-face using the Social Anxiety Scale for Adolescents, the Smartphone Addiction Proneness Scale, and the Multidimensional Scale of Perceived Social Support. Significantly higher levels of social anxiety were associated with females of lower economic status who reported more gaming hours and higher levels of proneness to smartphone addiction. Familial social support significantly mediated the relationship between proneness to smartphone addiction and social anxiety, controlling for the other covariates in the social anxiety model. Familial social support reduced the impact of proneness to smartphone addiction on social anxiety. Nurses may supplement treatment for reducing social anxiety in adolescents suffering from proneness to smartphone addiction by fostering sources of familial social support.

Prevalence of overweight/obesity, and associated factors among adolescents aged 12 ∼ 15 in Shandong Province, China: A cross-sectional study

Overweight/obesity among adolescents in Shandong Province, China, has been rising, posing significant public health challenge. Comprehensive investigation is needed to develop effective interventions. Following the Strengthening the Reporting of Observational Studies in Epidemiology guidelines, a stratified random cluster sampling approach was used from September to October 2023 across 17 cities in Shandong Province. The study included 165 middle schools, surveying 99,638 students aged 12 ∼ 15. After applying exclusion criteria, 97,356 students (97.71% effective rate) completed anthropometric measurements and questionnaires. Overweight/obesity were assessed based on national and international standards. Univariable chi-square test and multivariable logistic regression were used to analyze factors influencing overweight/obesity. In 2023, the overweight/obesity rate among 12 ∼ 15-year-olds in Shandong was 19.75%. Significant factors included sex, age, residence, family income, parental weight status and activity, mother’s gestational diabetes history, birth weight, physical activity, sleep, screen time, homework, and diet. Girls, older adolescents, and those with physically active parents or who themselves engaged in over 1.5 hours of daily physical activity had lower odds of being overweight/obese. Adequate sleep and frequent consumption of vegetable and fruit were also protective. Higher odds were associated with urban residence, high family income, overweight/obese parents, maternal gestational diabetes, high birth weight, excessive screen time, extensive homework, and frequent fast food consumption. Overweight/obesity in Shandong adolescents is influenced by multiple determinants. Holistic interventions addressing genetic, behavioral, and environmental factors are essential for promoting healthier lifestyles and reducing the prevalence in this demographic.

Understanding the Pathology of Major Depression in a Non-clinical Student Sample: The Role of Mental Pain, Cognitive Emotion Regulation, Self-Compassion, and Anxiety

Background: Severe psychological or mental pain is an experience of discomfort that can be associated with mental illness (such as major depression) or loss (such as the death of a child). Objectives: The aim of this study is to understand the pathology of major depression using a non-clinical student sample by assessing the roles of mental pain, cognitive emotion regulation, self-compassion, and anxiety. Methods: This cross-sectional study selected a sample (n = 300) using a multi-stage random cluster sampling method. Data was collected using the Orbach & Mikulincer Mental Pain Questionnaire (OMMP), the Cognitive Emotion Regulation Questionnaire (CERQ), the Self-Compassion Scale-Short Form (SCS-SF), the Beck Anxiety Inventory (BAI), and the Beck Depression Inventory-II (BD-II). Results: The results of the forward multiple linear regression model showed significant standardized beta coefficients for the following variables: Anxiety and depression (β = 0.21, P = 0.002), mental pain and depression (β = 0.436, P < 0.001), maladaptive cognitive emotion regulation strategies and depression (β = 0.21, P = 0.002), negative dimensions of self-compassion and depression (β = 0.082, p = 0.041), adaptive cognitive emotion regulation strategies and depression (β = -0.135, P = 0.031), and positive dimensions of self-compassion and depression (β = -0.078, P = 0.042). Additionally, the results indicated that 56% of the variance in depression is explained by mental pain, cognitive emotion regulation, self-compassion, and anxiety (P < 0.001). Conclusions: The results of this study indicate that therapies focused on emotional regulation and self-compassion can effectively address emotional problems, anxiety, and depression in individuals with depression.

Parental ADHD knowledge and medical visit status of school-aged children in Shanghai

IntroductionThe diagnosis and care of children and adolescents with neurodevelopmental disorders presents a public health crisis in China. Attention deficit hyperactivity disorder (ADHD) is one of the most frequent conditions. Many Chinese children and adolescents with ADHD are underdiagnosed and undertreated. This study aimed to evaluate the awareness and attitude parents have about ADHD, and investigated potential factors influencing ADHD medical visit status among school-aged children in Shanghai.MethodsA random cluster sampling method was used, and four primary schools in Shanghai were selected. One class was randomly selected from each grade, including students and their parents. Parents completed the Swanson, Nolan, and Pelham Version IV Questionnaire (SNAP-IV) parent form and questionnaire concerning ADHD awareness, knowledge, attitude and status of ADHD medical visit. Descriptive analysis was conducted on the overall results and logistic regression analysis was performed to explore the influencing factors of ADHD medical visit.ResultsWe received 617 valid questionnaires. There were 313 boys (50.7%) and 304 girls (49.2%), with a median age of 8 years old (p25 = 7, p75 = 9). 42.4% parents believed they had some knowledge about ADHD, and 73.5% of them thought ADHD was a neurologically based disorder or neurological condition by nature. Parental ADHD information came from the following sources: Internet/TV (n = 458, 74.2%), families/friends (n = 267, 43.2%), print publication (n = 208, 33.7%), psychiatrists/pediatricians (n = 192, 31.1%), schools/teachers (n = 186, 30.1%) and other ADHD patients (n = 48, 7.7%). When children had ADHD-like behaviors, most parents (61.5%) educated children to behave themselves, 59.1% parents tried to get help from psychiatrists/pediatricians, 55.5% of them would ask psychologist for help. In terms of the ADHD prevalence, the SNAP-IV positive screen rate was 4.3% (n = 27). Only 33.3% (9/27) of parents went to the hospital for consultation and treatment. Multivariate logistic regression model showed that parental knowledge about ADHD (OR = 13.67, 95%CI: 1.72, 144.39, P = 0.01) was significantly correlated with the medical visit. Parents with sufficient knowledge of ADHD tend to visit hospital for help when they thought their children had ADHD related symptoms.ConclusionsThe majority of parents accepted ADHD as a neurodevelopmental disorder by nature, but some parents still had certain misunderstandings about ADHD. The main source of information for parents to obtain information about ADHD was through the TV/Internet. Parents’ perceptions and knowledge were key to whether children received appropriate treatment for their ADHD. However, medical visits to address ADHD among school-aged children were still lower than expected. Government and healthcare institutes should work to improve ADHD public awareness and to help patients and their families gain access to mental health resources.

Analysis of the relationship between solar greenhouse operation and occupational high incidence diseases

Objective: To understand the health status of solar greenhouse workers, to provide scientific basis for the development of occupational high incidence diseases prevention and control strategies. Methods: In July 2019, a random cluster sampling method was used to select 245 workers engaged in solar greenhouse vegetable cultivation in Daba Village, Jingyuan County, Baiyin City, Gansu Province as the solar greenhouse operation group. Matched by gender, age, marital status, body mass index (BMI), 282 people from adjacent Shaliang Village who did not engage in solar greenhouse operation were selected as the control group. Field investigation and health examination were carried out among the study subjects. The general situation, facial features examination results, ophthalmic examination results, bone and joint examination results and skin examination results were compared between the two groups. And the multiple logistic regression analysis was used to analyze the influencing factors of abnormal bone and joint examination (upper limbs, lower limbs, hands and spine bone joints) in study subjects. Results: There were statistically significant differences in smoking age and alcohol consumption between the two groups (P<0.001). Compared with the control group, the abnormal detection rates of nose examination, throat examination, slit lamp examination, conjunctival examination, lower limb bone joint examination, hand bone joint examination, spine examination, head and neck skin examination, trunk skin examination, upper limb skin examination, and lower limb skin examination in the solar greenhouse operation group were higher, and the differences were statistically significant (χ(2)=11.53, 7.94, 9.92, 27.93, 79.32, 81.42, 9.43, 6.79, 9.76, 4.34, 8.29, P<0.05). Multivariate logistic regression analysis showed that after adjusting for gender, age, marital status, education level, BMI, compared with the control group, solar greenhouse operation was a risk factor for abnormal bone and joint examination (OR=1.178, 95%CI: 1.151-2.143, P=0.001) . Conclusion: Solar greenhouse operation has a certain harmful effect on health of workers, and solar greenhouse workers have an increased risk of abnormal diseases of upper limbs, lower limbs, hands and spine bone joints.

Blood DNA methylation in post-acute sequelae of COVID-19 (PASC): a prospective cohort study

DNA methylation integrates environmental signals with transcriptional programs. COVID-19 infection induces changes in the host methylome. While post-acute sequelae of COVID-19 (PASC) is a long-term complication of acute illness, its association with DNA methylation is unknown. No universal blood marker of PASC, superseding single organ dysfunctions, has yet been identified. In this single centre prospective cohort study, PASC, post-COVID without PASC, and healthy participants were enrolled to investigate their symptoms association with peripheral blood DNA methylation data generated with state-of-the-art whole genome sequencing. PASC-induced quality-of-life deterioration was scored with a validated instrument, SF-36. Analyses were conducted to identify potential functional roles of differentially methylated loci, and machine learning algorithms were used to resolve PASC severity. 103 patients with PASC (22.3% male, 77.7% female), 15 patients with previous COVID-19 infection but no PASC (40.0% male, 60.0% female), and 27 healthy volunteers (48.1% male, 51.9% female) were enrolled. Whole genome methylation sequencing revealed 39 differentially methylated regions (DMRs) specific to PASC, each harbouring an average of 15 consecutive positions, that differentiate patients with PASC from the two control groups. Motif analyses of PASC-regulated DMRs identify binding domains for transcription factors regulating circadian rhythm and others. Some DMRs annotated to protein coding genes were associated with changes of RNA expression. Machine learning support vector algorithm and random forest hierarchical clustering reveal 28unique differentially methylated positions (DMPs) in the genome discriminating patients with better and worse quality of life. Blood DNA methylation levels identify PASC, stratify PASC severity, and suggest that DNA motifs are targeted by circadian rhythm-regulating pathways in PASC. This project has been funded by the following agencies: NIH-AI173035 (A. Jaitovich and R. Alisch); and NIH-AG066179 (R. Alisch).

Prevalence of burnout among military personnel in the plateau region of China: a cross-sectional survey

ObjectivesThe geographical environment and military activities in the plateau area pose potential work-related stressors for military personnel, leading to burnout which is an external manifestation of internal energy exhaustion caused by stress. Without countermeasures, this can result in serious military problems. This study aims to examine the association between burnout and occupational stressors among military personnel stationed in the plateau area of China.Material and methodsA stratified randomized cluster sampling survey was conducted among 2026 military personnel from 6 different troops stationed in the plateau area of China. The Chinese Maslach Burnout Inventory-General Survey(MBI-GS in Chinese) was administered from March 2022 to December 2023, and data were analyzed using SPSS version 25.ResultsA total of 2026 military personnel participated in the survey. The mean overall burnout score was 3.37 ± 0.73, with emotional exhaustion at 2.69 ± 0.89, depersonalization at 3.58 ± 0.92, and professional achievement at 3.81 ± 0.85 levels respectively reported by participants on average scale scores ranging from zero to six. Severe level of burnout was reported by 43.2% of participants while medium level of burnout was reported by 54 .3%. Age, education level, length of military service, and household income were identified as important factors influencing burnout.ConclusionThis study highlights a relatively high prevalence of burnout among military personnel stationed in plateau areas necessitating attention towards their occupational health particularly focusing on working hours and economic aspects so as to formulate effective policies and implement intervention measures that strengthen career development for soldiers deployed in such regions.

Reproductive history is associated with functional disabilities and symptoms in women with knee osteoarthritis: a case-control study

ObjectivesStudies that have examined the correlation between reproductive history and knee osteoarthritis (KOA) have had heterogeneous findings. We aimed to investigate the reproductive history and its relationship with pain and physical dysfunction in women with KOA. This case-control study, comprising 204 women aged 50 and older with and without KOA recruited through random cluster sampling, was executed from February 2018 to October 2018 in the health centers of Tabriz City. The reproductive history questionnaire was completed for the subjects in two groups. Pain intensity and functional dysfunction caused by KOA were evaluated using the Visual analogue scale and the Western Ontario and McMaster index, respectively.ResultsThe women’s age of menarche in the case group was significantly lower (p = 0.031), and the number of pregnancies (p = 0.017) and the average duration of breastfeeding (p = 0.039) were substantially higher than those of the control group. Older age at the first menstruation (OR = 0.851) was a protective factor, and higher parity (OR = 8.726) was a risk factor for KOA. In the women with KOA, the younger age of the mother at the birth of the first alive baby and the longer duration of breastfeeding were associated with higher pain intensity and functional disorders.

Triple-drug therapy with ivermectin, diethylcarbamazine and albendazole for the acceleration of lymphatic filariasis elimination in Kenya: Programmatic implementation and results of the first impact assessment.

The World Health Organization (WHO) endorsed the use of triple-drug mass drug administration (MDA) regimen with ivermectin, diethylcarbamazine (DEC) and albendazole (commonly abbreviated as IDA) to accelerate the elimination of lymphatic filariasis (LF) as a public health problem in settings where onchocerciasis is not co-endemic. The National Programme for Elimination of LF (NPELF) in Kenya was among the first adopters of the IDA-MDA and two annual rounds were provided in 2018 and 2019 to the residents of Lamu County and Jomvu sub-County in the coast region. This study documented the feasibility of successfully delivering the two rounds of IDA-MDA. An operational research study was undertaken to determine efficient sampling strategies, indicators, and the appropriate population groups that could be used for the monitoring and evaluation of LF programs using IDA-MDA for the elimination of the disease as a public health problem. Two cross-sectional surveys were conducted at baseline in 2018 before IDA-MDA and an impact assessment 17 months after the second round of IDA-MDA. The reported epidemiological treatment coverage was at least 80% in all implementation units during each round of IDA-MDA. Blood samples were tested for filarial antigenemia using commercial Filariasis Test Strips (FTS) and any individual found to be positive was tested again at night for the presence of microfilariae in finger prick blood smears using microscopy. The overall prevalence of circulating filarial antigen (CFA) was relatively low at the baseline survey with Jomvu having 1.39% (95% CI: 0.91, 2.11) and Lamu having 0.48% (95% CI: 0.21, 1.13). Significant reduction in CFA prevalence was observed during the impact assessment after the two annual rounds of mass treatment. The overall relative reduction (%) in CFA prevalence following the two rounds of MDA with IDA was significant in both Jomvu (52.45%, Z = -2.46, P < 0.02) and Lamu (52.71%, Z = -1.97, P < 0.05). Heterogeneity, however, was observed in the CFA prevalence reduction between random and purposive clusters, as well as between adult and child populations. The results of the impact assessment survey offered strong evidence that it was safe to stop the IDA-MDA in the two EUs because transmission appears to have been interrupted. It is also important to implement a post-treatment surveillance system which would enable efficient detection of any recrudescence of LF transmission at a sub-evaluation unit level. Our findings show that IDA-MDA may be considered for acceleration of LF elimination in other settings where onchocerciasis is not co-endemic.

Maternal victimization and neglected offspring: Child marriage, IPV and depression symptoms among Salar Muslim women

BackgroundChild neglect is prevalent in western rural China, yet there is limited research among ethnic minority communities. The Salar, a Turkic-Muslim ethnic minority residing primarily in western China, also face this specific problem. The group is deeply influenced by ethnicity, Islam and Chinese Confucianism, which in turn makes women vulnerable to child marriage and IPV. These victimizations, coupled with various life stressors, further complicate the challenges of providing adequate care for their children. ObjectiveThis study hypothesizes a relationship between child neglect and maternal child marriage, IPV victimization, and depression symptoms. Participants and setting201 married Salar women from five villages in Xunhua Salar Autonomous County, China, were randomly selected to participate in the study. MethodA probability proportional to size (PPS) sampling approach was used to collect a random representative multi-stage cluster sample in 2022. Random effects Poisson regression models were used to test the hypotheses. ResultsThe participants reported a 65.6 % rate of child neglect and a 30.8 % rate of IPV in the past year. 37.6 % experienced child marriage. Results revealed significant associations between child neglect and child marriage, IPV, and depression symptoms. A two-way interaction between IPV and depression symptoms was strongly positively associated with child neglect. ConclusionsThis research indicates that Salar Muslim mothers who have experienced child marriage, adulthood victimization, and depression are at a higher risk of neglecting their children. The findings represent a valuable initial step toward researching and addressing the protection needs of women and children from Muslim ethnic minorities in China.

The structural model of marital satisfaction based on relational beliefs with the mediating role of cognitive emotion regulation in married women

Introduction: Inefficiency in the process of emotion regulation prevents the emergence of efficient behaviors and appropriate coping responses to the situation in marital relationships by the individual, which seems to be influenced by relational beliefs. Aim: The present study aimed to formulate a structural model of marital satisfaction based on relational beliefs with the mediating role of cognitive emotion regulation in married women. Methods: The current research was descriptive-correlation based on the method of structural equations and the statistical population of the present study consisted of all married women between the ages of 30 and 50 who were referred to counseling centers in Tehran in the first six months of 2022, among them 371 women were selected using the random clusters sampling method. The research tools included ENRICH Marital Satisfaction Scale, Relationship Belief Inventory, and Cognitive Emotion Regulation Questionnaire. For data analysis, Pearson's correlation method and structural equations were used with SPSS version 22 and AMOS version 24 software. Results: The results of the present study showed there is an indirect and significant relationship between relational beliefs and marital satisfaction with the mediation of positive emotional cognitive regulation (P=0.003, Z=-2.11). There is an indirect and significant relationship between relational beliefs and marital satisfaction with the mediation of negative emotional cognitive regulation (P=0.009, Z=-1.78). Conclusion: The results showed that marital satisfaction is predicted based on communication beliefs with the mediating role of cognitive emotion regulation in married women. It is suggested that couple therapists and family therapists pay attention to relational beliefs and cognitive emotion regulation strategies derived from them in counseling and couple therapy to increase marital satisfaction.

Experienced and internalized weight stigma among Spanish adolescents

Background and objectiveWeight stigma has negative consequences for both physiological and psychological health. Studies on weight stigma in adolescence, particularly from general populations, are scarce in the Mediterranean area. The main aim of this study is to describe the prevalence of experienced and internalized weight stigma among a representative sample of adolescents from the Spanish city of Terrassa, and to determine its association with sociodemographic variables and weight status.MethodsDrawing on data from the initial assessment of a longitudinally funded project on weight stigma in adolescents, a cross-sectional survey-based study was conducted using random multistage cluster sampling. Weight stigma experiences, their frequency and sources, and weight bias internalization with the Modified Weight Bias Internalization Scale (WBISM) were assessed in a sample of 1016 adolescents. Adjusted odds ratios (AOR) between sociodemographic variables, weight status and having experienced weight stigma, and having reported high scores of WBISM (WBISM ≥ 4) were estimated by multiple logistic regression models.ResultsThe prevalence of weight-related stigma experiences was 43.2% in the sample (81.8 in adolescents with obesity) and the prevalence of high levels of weight bias internalization was 19.4% (50.7 in adolescents with obesity). Other kids and school were the most prevalent sources of weight stigma, with society and family being other significant sources of stigma reported by girls. A significantly higher risk of having experienced weight stigma was observed in girls (AOR = 2.6) and in older adolescents (AOR = 1.9). Compared to normal weight adolescents, all weight statuses showed higher risk, being 3.4 times higher in adolescents with underweight and reaching 11.4 times higher risk in those with obesity. Regarding high levels of weight bias internalization, girls had a risk 6.6 times higher than boys. Once again, a “J-shaped” pattern was observed, with a higher risk at the lowest and highest weight statuses. The risk was 6.3 times higher in adolescents with underweight, and 13.1 times higher in adolescents with obesity compared to those with normal weight.ConclusionsConsidering the high prevalence of experienced and internalized weight stigma among adolescents in Spain, especially in adolescents with obesity and girls, it seems important to implement preventive strategies in different settings and address all sources of stigma.

Distribution and prevalence of refractive error in Iranian adult population results of the PERSIAN eye cohort study PECS

The Persian Eye Cohort Study, a population-based cross-sectional study from 2015 to 2020, examined refractive error prevalence among 48,618 Iranian adults aged 31 to 70. The study encompassed six centers in Iran, employing random cluster sampling for demographic, medical, and socioeconomic data collection through interviews. Ophthalmic exams included visual acuity, automated and manual objective refraction, subjective refraction, slit lamp, and fundus examinations. Using the spherical equivalent definition, the sample population was categorized into groups. Results indicated a mean age of 49.52 ± 9.31 and a mean refractive error of 0.26 diopters (D) ± 1.6 SD (95% CI − 0.27 to -0.24), ranging from -26.1 to + 18.5 SD. Prevalence of myopia (< −0.5D) and hyperopia (> + 0.5D) was 22.6% (95% CI 22.2–23%) and 12.5% (95% CI 12.1–12.8%), respectively. Regarding different age groups, the prevalence of hyperopia and astigmatism exhibited a steady and significant rise with increasing age (p-value < 0.001 for both). The prevalence of Myopia, however, showed a distinctive pattern, initially increasing in adults under 45, declining in those aged 55–64, and rising again among individuals aged 60 and older. Female gender, older age, urban residency, higher education, higher income, and Fars ethnicity were significantly related to a higher prevalence of myopia (p-value < 0.001 for all). Female gender (p-value < 0.001), aging (p-value < 0.001), urban residency (p-value = 0.029), and lower-income (p-value = 0.005) were significantly related to higher prevalence of hyperopia. Astigmatism (> 1D) was prevalent in 25.5% of participants (95% CI 25.1–25.9%) and correlated with male gender, aging, urban residency, illiteracy, and higher income (p-value < 0.001, < 0.001, < 0.001, < 0.001, 0.014, respectively). The study’s comparison with regional and international surveys highlighted the increase in myopia among those over 65 due to higher nuclear cataract rates in older adults. Myopia positively related to education, income, and urban residency, while hyperopia did not exhibit such associations.

Objective: To understand the utilization and characteristics of outpatient services for pneumoconiosis patients within two weeks in Chongqing, and analyze the influencing factors, so as to provide reference for relevant policy making. Methods: From October 2020 to October 2022, 1771 pneumoconiosis patients who met the inclusion criteria were selected by multi-stage stratified random cluster sampling. A questionnaire survey was conducted on their basic situation, utilization of outpatient services within two weeks, treatment for pneumoconiosis-related symptoms, and selection of medical service institutions using χ(2)-test and logistic regression analysis. Results: All the 1771 pneumoconiosis patients were male, with the average age of (56.1±10.19) years old. In the pneumoconiosis patients were treated in outpatient department within 2 weeks.40.0% (204/510) of aged 41~50 years Rural patients accounted for 87.8% (448/510) ; 65.1% (332/510) of silicosis patients, 37.5% (191/510) of stage II patients, 75.1% (383/510) of patients did not continue to engage in dust work after diagnosis of pneumoconiosis, and 57.1% (291/510) of patients never had work-related injury insurance at work. The outpatient rate within two weeks of pneumoconiosis related assistance and subsistence allowance was 17.6% (90/510) and 12.5% (64/510), respectively. The average self-health score of the patients was (52.9±16.2). 28.2% of the patients had purchased work-related injury insurance; Among the 1204 patients who received the treatment within two weeks, 42.2% were in the outpatient department, 20.7% were in the inpatient department, and 36.9% were self-buyers. There was a significant difference between the different treatment methods of the patients (χ(2)=27.53, P<0.05). There was a significant difference in patients from different residence choosing to visit different medical institutions (χ(2)=13.97, P<0.05). The stage of pneumoconiosis, presence of complications, presence of work injury insurance, self-health score, and whether he/she has been hospitalized in the past year are the important factors affecting the outpatient treatment of pneumoconiosis patients. Conclusion: The utilization of outpatient service of pneumoconiosis patients is influenced by demographic sociology, social support and disease characteristics. The quality of occupational disease medical service in primary health institutions should be strengthened so that pneumoconiosis patients can get convenient and effective treatment. Establish a more perfect social security support system to reduce the disease burden of pneumoconiosis patients.
