Residential Proximity to Oil and Gas Development and Mental Health in a North American Preconception Cohort Study: 2013-2023.

Objectives. To evaluate associations between oil and gas development (OGD) and mental health using cross-sectional data from a preconception cohort study, Pregnancy Study Online. Methods. We analyzed baseline data from a prospective cohort of US and Canadian women aged 21 to 45 years who were attempting conception without fertility treatment (2013-2023). We developed residential proximity measures for active OGD during preconception, including distance from nearest site. At baseline, participants completed validated scales for perceived stress (10-item Perceived Stress Scale, PSS) and depressive symptoms (Major Depression Inventory, MDI) and reported psychotropic medication use. We used log-binomial regression and restricted cubic splines to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs). Results. Among 5725 participants across 37 states and provinces, residence at 2 km versus 20 to 50 km of active OGD was associated with moderate to high perceived stress (PSS ≥ 20 vs < 20: PR = 1.08; 95% CI = 0.98, 1.18), moderate to severe depressive symptoms (MDI ≥ 20 vs < 20: PR = 1.27; 95% CI = 1.11, 1.45), and psychotropic medication use (PR = 1.11; 95% CI = 0.97, 1.28). Conclusions. Among North American pregnancy planners, closer proximity to OGD was associated with adverse preconception mental health symptomatology.

The employment expectations of adolescents: Examining the role of social origin, parental support, and personality traits.

Early life course conditions and the social origin of families frequently influence the inequalities people experience in adulthood. The transition from education to work is a challenging period during which adolescents make their first employment-related choices and establish the course of their careers. Future expectations guide adolescents' employment-related choices and are assumed to influence future employment outcomes. Therefore, this paper investigates whether family (dis)advantages affect adolescents' employment expectations. We assess various underlying mechanisms that may influence the relationship between social origin and adolescents' employment expectations by using cross-sectional data from the German Socio-Economic Panel (SOEP: 2006-2018), specifically a youth questionnaire administered at age 17. Three key findings emerge. First, family disadvantages, particularly an insecure parental labor market participation, influence the employment expectations of adolescents negatively. Second, supportive parenting does not mediate the relationship between social origin and the employment expectations of adolescents; instead, it functions as an additional positive factor. Third, supportive parenting creates more optimistic employment expectations because it fosters specific "beneficial" personality traits, such as extraversion, conscientiousness, openness, agreeableness, and internal control beliefs.

Active Travel, Public Transport and the Built Environment in Youth: Interactions with Perceived Safety, Distance to School, Age and Gender

IntroductionThis study examined interactive effects of the built environment, perceived safety, age and gender on active travel and public transport use among adolescents for school journeys. MethodThis study used cross-sectional data from 440 adolescents (mean age 15.4 ± 1.5 years, 58% girls) in Melbourne, Australia. Adolescents self-reported their school travel modes, perceptions of traffic and personal safety. Exclusive active travel and public transport use to/from school were determined. Objective built environment features around home and school (1 km buffer) were generated. Multilevel logistic regression was used to estimate main and interactive associations. ResultsOverall, 18% travelled exclusively by active travel and 32% by public transport. Distance to school was negatively associated with exclusive active school travel (OR=0.44, 95%CI: 0.34, 0.56). Distance to school moderated the association between some built environment attributes (land use mix, residential density around home, distance to public transport stops) and odds of active school travel. There was a positive association between residential density around school and active school travel among those who perceived their traffic environment to be safer. Boys were more likely than girls to use public transport if they lived further from school. A negative association between distance to a public transport stop from home and the odds of public transport use was observed among those who perceived their environment to be less safe. ConclusionThe findings highlight the complexity of influences on mode choice for the school journey. Distance to school remains one of the most important predictors of active travel/public transport use. Supportive built environment attributes, such as a diverse mix of land use around home had facilitating effects on active travel among adolescents who lived closer to school. Multilevel interventions that target both the environment and perceived safety are needed to promote active travel and public transport use among adolescents.

Gottman's sound relationship house and relational resilience through infertility for couples.

Some couples report that their relationship satisfaction increases through the experience of infertility. Few studies exist which explain how this phenomenon occurs through specific variables. We hypothesized that John Gottman's constructs of friendship and intimacy as well as shared meaning could explain how couples can achieve increased relationship satisfaction. We examined a regression analysis of cross-sectional retrospective individual data for couples who are either experiencing infertility currently or have done so in the recent past. In our nonclinical sample (n = 903), mediation analyses indicated significant influencing pathways for the Gottman shared meaning system, indicating that this construct may explain how couples achieve greater emotional bonding and couple satisfaction through infertility. These findings provide couple therapists with potential areas of focus for couples navigating infertility through the lens of Gottman Method Couple Therapy, including ways to encourage deeper mutual shared meaning amidst the infertility experience.

Do Protective Tariffs Influence Firms’ Competitive Stance? Application of a Competitive Leverage Model in The Presence of Simultaneous Equation and Sample Selectivity Bias

ABSTRACT: We propose a Competitive Leverage model, and apply it to analyze the impact of tariffs on the attitudes of domestic import-competing firms, especially regarding their disincentives to maintain a Competitive Stance against foreign competitors in the domestic market. We propose that tariffs are a disincentive to the pursuit and maintenance of production efficiency in firms and industries. When countries implement tariff protection for their domestic firms, the most common excuse sounds reasonable, except that it is also economically flawed. While the short-run impacts of such a measure might seem plausible, its long-term effects appear to be less than favorable, and may, in fact, turn out to be damaging to the economy. The paper applies the competitive leverage concept in a unique way to highlight how tariffs distort the output levels of domestic firms, and gives an empirical analysis of the model, using USA data to verify the predictions of the model. Particularly, we develop a Cournot-competition type Competitive Leverage model, and use it to examine the role played by tariffs as a disincentive to a typical firm’s pursuit and maintenance of production efficiency. The competitive leverage model is formulated and applied to verify the effects of tariff protection from the typical domestic firm’s strategic interaction standpoint. We further apply cross-sectional data to carry out an empirical analysis of the model, to verify how tariffs impact the domestic firm’s output and pricing decisions. Our findings would enable us to contribute to the debate about the need to remove protective tariffs, on the grounds that tariffs do not only enable domestic firms to operate inefficiently, but also tends to distort the output and pricing outcomes that would otherwise have been realized in the free market. The results from the study are used to propose some major policy implications of imposing tariff protection, among which are that there is need for implementation of more deliberately sustained Research and development program on the part of domestic firms in the economy, to enable them withstand vigorous competition in a free-trade world. Also, since protective tariffs significantly increase firms’ profit rates, which in turn enables them to unduly earn and accumulate economic rents that amount to inefficiencies and distortions in free-market prices and quantities outcomes, governments should always resist any pressures from big businesses to impose protective tariffs against competition from international rivals. Yet a clear public policy implication from this paper is that, at the macro level, as the results suggest that a government policy that aims at protecting domestic firms through imposition of tariffs may have an adverse effect on the firms’ competitive stance in the industry, a practical message is for the government to impose only a moderate tariff at the most, if it must, especially as it relates to agricultural products.

Predicting informal dementia caregivers' desire to institutionalize through mining data from an eHealth platform.

Dementia is a leading factor in the institutionalization of older adults. Informal caregivers' desire to institutionalize (DI) their care recipient with dementia (PwD) is a primary predictor of institutionalization. This study aims to develop a prediction model for caregivers' DI by mining data from an eHealth platform in a high-prevalence dementia country. Cross-sectional data were collected from caregivers registering on isupport-portugal.pt. One hundred and four caregivers completed the Desire to Institutionalize Scale (DIS) and were grouped into DI (DIS score ≥ 1) and no DI (DIS score = 0). Participants completed a comprehensive set of sociodemographic, clinical, and psychosocial measures, pertaining to the caregiver and the PwD, which were accounted as model predictors. The selected model was a classification tree, enabling the visualization of rules for predictions. Caregivers, mostly female (82.5%), offspring of the PwD (70.2), employed (65.4%), and highly educated (M 15 years of schooling), provided intensive care (Mdn 24h. week) over a median course of 2.8 years. Two-thirds (66.3%) endorsed at least one item on the DIS (DI group). The model, with caregivers' perceived stress as the root of the classification tree (split at 28.5 points on the Zarit Burden Interview) and including the ages of caregivers and PwD (split at 46 and 88 years, respectively), as well as cohabitation, employed five rules to predict DI. Caregivers scoring 28.5 and above on burden and caring for PwD under 88 are more prone to DI than those caring for older PwD (rules 1-2), suggesting the influence of expectations on caregiving duration. The model demonstrated high accuracy (0.83, 95%CI 0.75, 0.89), sensitivity (0.88, 95%CI 0.81, 0.95), and good specificity (0.71, 95%CI 0.56, 0.86). This study distilled a comprehensive range of modifiable and non-modifiable variables into a simplified, interpretable, and accurate model, particularly useful at identifying caregivers with actual DI. Considering the nature of variables within the prediction rules, this model holds promise for application to other existing datasets and as a proxy for actual institutionalization. Predicting the institutional placement of PwD is crucial for intervening on modifiable factors as caregiver burden, and for care planning and financing.

How does chronic disease influence subjective life expectancy among middle-aged and older adults? Evidence from the China Health and Retirement Longitudinal Study (CHARLS) 2018 cross-sectional data.

Chronic diseases have become one of the most important factors threatening human health. Subjective life expectancy (SLE) describes an individual's expectation or subjective perception of lifespan. This article aims to explore the relationship between chronic diseases and SLE, as well as the differences among different age groups and different types of chronic diseases in this relationship. China Health and Retirement Longitudinal Study (CHARLS) is a nationwide longitudinal study that evaluates the social, economic, and health conditions of middle-aged and older adult families and individuals aged 45 and above in China. In this study, CHARLS used probability proportional to size sampling (PPS sampling) to ensure the breadth and representativeness of the sample. This study selected cross-sectional data from CHARLS 2018, removed missing values, and obtained a valid sample of 10,658 middle-aged and older individuals, of whom 8564 had chronic diseases. After controlling demographic, health behavior, socioeconomic, psychological, and social security factors, an ordered logistic regression was performed to explore the relationship between chronic disease and SLE in middle-aged and older adults. The results show that chronic diseases negatively correlate with SLE in middle-aged and older adults. Middle-aged and older adults with chronic diseases are 36.2% less likely to have high life expectancy than those without chronic diseases. Many different types of chronic diseases are negatively correlated with SLE. Cancer is most negatively correlated with SLE, far exceeding other chronic diseases. Chronic disease and SLE of middle-aged and older adults have age-heterogeneous differences. For middle-aged people aged 45-59 and young older adults aged 60-79, there is a significant correlation between chronic diseases and SLE. However, there is no correlation between chronic diseases and subjective life expectancy in the older population aged 80 and above. The government and society should pay close attention to the prevention and treatment of chronic diseases among middle-aged and older adults and adjust policies and measures according to the population's age structure. In addition, the government and society should pay attention to the spiritual needs of middle-aged and older adults. The government and society should pay more attention to cancer patients. Finally, the scientific research team should also strengthen research on chronic diseases, research and development of specific drugs and vaccines, improve the cure rate of chronic diseases, promote people's health, and make people no longer afraid of diseases.

The association of sociodemographic factors with total and item-level semantic fluency metrics.

We aimed to estimate the association of age, education, and sex/gender with semantic fluency performance as measured by the standard total number of words as well as novel item-level metrics and to descriptively compare associations across cohorts with different recruitment strategies and sample compositions. Cross-sectional data from 2,391 individuals from three cohorts were used: Washington Heights/Inwood Columbia Aging Project, a community-based cohort; Second Manifestations of ARTerial disease-Magnetic Resonance, a clinic-based cohort; and African American Alzheimer's Disease Genetics Study, a volunteer-based cohort. Total number of correct words and six item-level semantic fluency metrics were included as main outcomes: average cluster size, number of cluster switches, lexical/Zipf frequency, age of acquisition, and lexical decision response time. General linear models were run separately in each cohort to model the association between sociodemographic variables and semantic fluency metrics. Across cohorts, older age was associated with a lower total score and fewer cluster switches. Higher level of education was associated with naming more words, performing more cluster switches, and naming words with a longer lexical decision response time, lower frequency of occurrence, or later age of acquisition. Being female compared to male was associated with naming fewer words, smaller cluster sizes, naming words with a longer lexical decision response time, and lower age of acquisition. The effects varied in strength but were in a similar direction across cohorts. Item-level semantic fluency metrics-similar to the standard total score-are sensitive to the effects of age, education, and sex/gender. The results suggest geographical, cultural, and cross-linguistic generalizability of these sociodemographic effects on semantic fluency performance.

Attitudes toward mothers as sexual beings and the sexual functioning of parents.

Research has shown that negative sexual attitudes are associated with lower levels of sexual functioning among men and women, however, little is known about how attitudes about mothers as sexual beings are associated with sexual functioning for parents. The aim of the current study was to examine how attitudes toward mothers as sexual beings (ATMSB) were associated with sexual functioning for women and partners of women among parents with young children. Cross-sectional retrospective data were collected online via Qualtrics Panels from 475 women and men (partnered to women) who reported having their first child within the last 5 years.Outcomes: The Revised Female Sexual Function Index and revised Expanded Prostate Cancer Index Composite-Short Form were used to measure sexual function in women and men, respectively. Results indicated that after controlling for age and relationship length, more positive ATMSB predicted higher levels of sexual functioning (and multiple domains of functioning) for men and women.Clinical Implications: These findings indicate that sexual functioning, especially in parents, is linked to the attitudes held toward seeing mothers as inherently sexual (or not). This is the first study to examine how attitudes toward mothers as sexual beings can impact sexual functioning, though the cis heterosexual mostly white sample is a notable limitation. ATMSB may need to be examined and challenged in the context of treating sexual dysfunction during this transitional period for mothers and those partnered to mothers.

Profiles of met and unmet care needs in the oldest-old primary care patients with cognitive disorders and dementia - results of the AgeCoDe and AgeQualiDe study.

The prevalence of MCI and dementia is increasing as the oldest-old population grows, requiring a nuanced understanding of their care needs. Few studies have examined need profiles of oldest-old patients with MCI or dementia. Therefore, this study aims to identify patients' need profiles. The data analysis included cross-sectional baseline data from N = 716 primary care patients without cognitive impairment (n = 575), with MCI (n = 97), and with dementia (n = 44) aged 85+ years from the multicenter cohort AgeQualiDe study "Needs, Health Service Use, Costs and Health-Related Quality of Life in a Large Sample of Oldest-Old Primary Care Patients [85+]". Patients' needs were assessed using the Camberwell Assessment of Need for the Elderly (CANE), and latent class analysis identified need profiles. Multinomial logistic regression analyzed the association of MCI and dementia with need profiles, adjusting for sociodemographic factors, social network (Lubben Social Network Scale, LSNS-6), and frailty (Clinical Frailty Scale, CSHA-CFS). Results indicated three profiles: 'no needs', 'met physical and environmental needs', and 'unmet physical and environmental needs'. MCI was associated with the met and unmet physical and environmental needs profiles; dementia was associated with the unmet physical and environmental needs profile. Patients without MCI or dementia had larger social networks (LSNS-6). Frailty was associated with dementia. Integrated care should address the needs of the oldest-old and support social networks for people with MCI or dementia. Assessing frailty can help clinicians to identify the most vulnerable patients and develop beneficial interventions for cognitive disorders.

THE ROLE OF KNOWLEDGE MANAGEMENT, INNOVATION, MOTIVATION AND JOB SATISFACTION IN IMPROVING EMPLOYEE PERFORMANCE (CASE: INDONESIA)

The purpose of this study is to examine how knowledge management affects employee creativity, motivation, and work satisfaction in Indonesia's printing sector. In 2024, questionnaires were randomly delivered to PT Penerbit Erlangga Group Jakarta employees in order to gather cross-sectional data. In order to investigate a particular population or sample, data were gathered using a quantitative approach based on positivism. Research tools were used to collect data, which were then statistically evaluated to test hypotheses. The findings indicate that while knowledge management has no detrimental effects on employee performance, it does have a favorable impact on employees' motivation, creativity, and job satisfaction in Indonesia's printing industry. Furthermore, employee performance is not positively impacted by innovation, but it is positively impacted by job satisfaction and motivation. The managerial ramifications of these results underscore how critical it is for printing companies to concentrate on initiatives that raise employee engagement and satisfaction, foster innovation, and enhance staff knowledge and abilities.

HIV Symptom Clusters Among Sexual Minority Men in Ghana, West Africa: A Cross-sectional Study.

The aims of this study were to determine if HIV symptoms among sexual minority men formed clusters and to examine the sociodemographic and clinical characteristics that are associated with these clusters. We analyzed cross-sectional data from Ghanaian sexual minority men (N = 225) living with HIV. We used both principal component analysis and multivariable linear regression. Our findings indicate that sadness (64.0%) and headache (62.7%) were the most prevalent symptoms among our sample. Seven symptom clusters were identified: neurological symptoms, psychological symptoms, gastrointestinal symptoms, dermatological symptoms, self-concept/self-esteem, weight/diet-related symptoms, and sleepquality and potential disturbances. Late HIV diagnosis was significantly associated with higher distress scores for all symptom clusters except for the self-concept/self-esteem and gastrointestinal symptoms clusters. The findings emphasize the importance of early HIV symptom identification.

The association between primary ovarian insufficiency and increased multimorbidity in a large prospective cohort

ObjectiveTo describe the prevalence of multimorbidity among individuals with premature ovarian insufficiency (POI) and early menopause, in comparison to average age of menopause. DesignProspective cohort SubjectsThis prospective cohort encompassed female postmenopausal individuals from the Canadian Longitudinal Study on Aging (CLSA). The CLSA collected cross-sectional data from 50,000 community-dwelling Canadians aged 45 to 85 between 2010 and 2015. ExposureThe primary exposure was primary ovarian insufficiency (defined by onset of menopause younger than 40 years). Comparators included average age of menopause (age 46 to 55 years), early menopause (40-45 years), late onset menopause (56-65 years), and those who underwent a hysterectomy. Main outcome measuresThe primary outcome was multimorbidity, which was defined as two or more chronic conditions. The secondary outcome was severe multimorbidity (defined as three or more chronic conditions) as well as frequencies of specific chronic conditions among a comprehensive list of 15 individual conditions. We assessed the association between multimorbidity and age at menopause using logistic regression and odds ratios, with confidence intervals set at 95%. Odds ratios were adjusted for known predictors of multimorbidity, including age, menopause hormone therapy (MHT), education, ethnicity, self-reported loneliness, living alone, BMI, smoking habits, nutritional risk, social participation, and physical activity. ResultsA total of 12,339 postmenopausal participants were included, of which 374 (3.0%) experienced POI and 1396 (11.3%) experienced early menopause. The prevalence of multimorbidity was 64.8% and 51.1% among those with POI and early menopause respectively. In contrast, only 43.9% of individuals with average age of menopause (age 46 to 55 years) had multimorbidity. The OR for multimorbidity in the POI population was 2.5 (95% CI 2.0-3.1) in comparison to those who underwent the average age of menopause. This relationship was maintained after adjustment for confounders (aOR 2.0, 95% CI: 1.5-2.5). The prevalence of severe multimorbidity was also double in the POI group in comparison in the average age group (39.2% versus 21.1%). There was significantly increased risk of ischemic heart disease (aOR 2.8, 95% CI: 1.7-4.7), gastric ulcers (aOR 1.6, 95% CI: 1.1-2.3) and osteoporosis (aOR 1.6, 95% CI: 1.2-2.1) in the POI group. ConclusionsIndividuals with POI and early menopause experience increased multimorbidity in comparison to those undergoing menopause at an average age. This trend persists even after adjusting for significant multimorbidity risk factors.

Racial Discrimination, Social Support, and Psychological Distress Among Black Pregnant Women.

Black pregnant women who experience racial discrimination are at an increased risk of psychological distress. Studies have not adequately addressed if social support may moderate the association between experiences of racial discrimination and psychological distress among Black pregnant women. We sought to examine the moderating effect of social support on the association between experiences of racial discrimination and psychological distress among Black pregnant women. We report findings based on cross-sectional data collected from 599 Black pregnant women enrolled in a prospective cohort study prior to the COVID-19 pandemic. Women completed questionnaires about experiences of racial discrimination (Experiences of Discrimination), social support (MOS Social Support Survey), and psychological distress (Psychological General Wellbeing Index). Women had an average age of 26 ± 5 years and gestational age at data collection of 17 ± 6 weeks. Approximately 53% of women reported ever experiencing racial discrimination in at least one situation, and 54% reported psychological distress. After adjustment for covariates, racial discrimination was associated with a 2.2-fold increase in psychological distress (odds ratio [OR] = 2.24; 95% confidence interval [CI] 1.35-3.70; P = .002). Low social support (scores below the median) was associated with a 3.8-fold higher likelihood of psychological distress (OR = 3.84, 95% CI 2.27-6.48, P < .001). Social support did not moderate the association of lifetime experiences of racial discrimination with psychological distress. Findings of the study contribute to evidence that lifetime experiences of racial discrimination and low levels of social support relate to psychological distress among Black pregnant women.

Social, behavioral and clinical risk factors are associated with clonal hematopoiesis.

Risk factors including smoking, alcohol intake, physical activity (PA), and sleep patterns have been associated with cancer risk. Clonal hematopoiesis (CH), including mosaic chromosomal alterations (mCAs) and clonal hematopoiesis of indeterminate potential (CHIP), is linked to increased hematopoietic cancer risk, and could be used as common pre-clinical intermediates for better understanding associations of risk factors with rare hematologic malignancies. We analyzed cross-sectional data from 478,513 UK Biobank participants without hematologic malignancies using multivariable adjusted analyses to assess the associations between lifestyle factors and CH types. Smoking was reinforced as a potent modifiable risk factor for multiple CH types, with dose-dependent relationships persisting post-cessation. Males in socially deprived areas of England had lower risk of mosaic loss of chromosome Y (mLOY), females with moderate/high alcohol consumption (2-3 drinks/day) had increased mLOX risk (OR=1.17, 95%CI:[1.09-1.25], p=8.31×10-6) compared to light drinkers, active males (moderate-high PA) had elevated risks of mLOY (PA Category 3: OR=1.06, 95%CI:[1.03-1.08], p=7.57×10-6) and men with high BMI (≥40) had reduced risk of mLOY (OR=0.57, 95%CI:[0.51-0.65], p=3.30×10-20). Sensitivity analyses with BMI adjustment attenuated the effect in the mLOY-PA associations (IPAQ2: OR=1.03, 95%CI:[1.00-1.06], p=2.13×10-2 and IPAQ3: OR=1.03, 95%CI:[1.01-1.06], p=7.77×10-3). Our study reveals associations between social deprivation, smoking, alcohol consumption, and CH risk, suggesting these exposures could contribute to common types of CH and potentially rare hematologic cancers. This study underscores the impact of lifestyle factors on CH frequency, emphasizing social, behavioral, and clinical influences and the importance of socio-behavioral contexts when investigating CH risk factors.

Depression, anxiety, stress, and current e-cigarette use: Results from the truth longitudinal cohort of youth and young adults (2022−2023)

ObjectiveTo examine associations between depression, anxiety, and stress, as measured by the Depression, Anxiety and Stress Scale (DASS-21) scale, with current e-cigarette use. MethodsData from the Truth Longitudinal Cohort – a nationally representative sample of youth and young adults – was collected between October 2022 to February 2023. The analytic sample was comprised of participants who provided information on e-cigarette use and the DASS-21 scale (N = 4198). Chi-square statistics were used to determine differences by current e-cigarette use across covariates and DASS-21 items. Logistic regression analyses were applied to the cross-sectional data to determine which scales predicted current e-cigarette use, adjusted for the effects of age, gender identity, race and ethnicity, parental educational attainment, perceived financial situation, and current use of alcohol, marijuana, and other tobacco use. ResultsThose who had severe/extremely severe levels of depression, anxiety, and stress had greater odds of current e-cigarette use, relative to those who had normal levels of depression, anxiety, and stress, even after adjusting for covariates. Results also demonstrated associations between age, race/ethnicity, parental education, and current use of alcohol, marijuana, and other tobacco products with current e-cigarette use. LimitationsCross-sectional analyses of self-reported data limit the ability to determine directionality of effects between depression, anxiety, stress, and current e-cigarette use. DiscussionMore severe levels of depression, anxiety, and stress were associated with a greater likelihood of current e-cigarette use. Future research is needed to evaluate changes in e-cigarette use, in response to depression, anxiety, and stress symptomatology.

How Does Internet Use Affect Citizen Political Participation? The Mediating Role of Social Networks

This study investigates the complex relationship between internet use and citizen political participation, emphasizing the mediating role of social networks. Using cross-sectional data from the 2021 Chinese Social Survey (CSS), we classify political participation into government-led and citizen-led activities and internet use into informational, entertainment-oriented, and service-oriented types. Overall, our findings reveal a positive correlation between internet use and both citizen-led participation and government-led participation (excluding voting), with a stronger association observed in the former. From a categorical perspective, informational and service-oriented internet use significantly influences all types of political participation, while entertainment-oriented use shows no significant correlation. Additionally, social networks mediate the relationship between internet use and political participation. Service-oriented internet use is more dependent on social networks to connect with political participation compared to information-oriented internet use. This study contributes to the ongoing debate on the impact of digital media on civic engagement by providing nuanced insights into how specific internet activities and social networks shape political participation in China.

Public Health Insurance and Labor Supply of Middle-aged and Elderly People in China

According to cross-sectional data in 2013 wave and 2015 wave of CHARLS, there is research for effects of public health insurance on labor supply of people who are middle-aged and elderly in China by Ordinary Least Square. China is facing severe labor supply problems because of the aging population. Moreover, people who are middle-aged and seniors play a significant role in Chinese labor market. The paper will focus on studying labor participation and the labor hours of middle-aged and older adults. Meanwhile, public health insurance is one of the focuses of this research. Nowadays, there is a significant public health insurance named New Rural Cooperative Medical insurance (NRCMI), which has been implemented for many years. It aims to support the health status of people who are middle-aged and seniors. After a series of calculations and studies, it shows that NRCMI has great effects on labor decisions of people in middle-aged and seniors. NRCMI can improve the labor participation by 11.6 percentage points, and it can also increase the labor hours by 239.343 hours. Therefore, NRCMI has a tremendous impact on China's labour supply, and the government should increase the promotion of NRCMI and ensure the full implementation.

Investigating the impact of dietary guidelines transition on cardiometabolic risk profile: a forensic analysis using diet quality metrics.

Evaluating dietary guidelines using diet quality (DQ) offers valuable insights into the healthfulness of a population's diet. We conducted a forensic analysis using DQ metrics to compare the Malaysian Dietary Guidelines (MDG-2020) with its former version (MDG-2010) in relation to cardiometabolic risk (CMR) for an adult Malaysian population. A DQ analysis of cross-sectional data from the Malaysia Lipid Study (MLS) cohort (n = 577, age: 20-65yrs) was performed using the healthy eating index-2015 (HEI-2015) framework in conformation with MDG-2020 (MHEI2020) and MDG-2010 (MHEI2010). Of 13 dietary components, recommended servings for wholegrain, refined grain, beans and legumes, total protein, and dairy differed between MDGs. DQ score associations with CMR, dietary patterns and sociodemographic factors were examined. Out of 100, total DQ scores of MLS participants were 'poor' for both MHEI2020 (37.1 ± 10.3) and MHEI2010 (39.1 ± 10.4), especially among young adults, males, Malays, and those frequently 'eating out' as well as those with greatest adherence toSugar-Sweetened Beverages pattern and lowest adherence toFood Plant pattern. Both metrics shared similar correlations with CMR markers, with MHEI2020 exhibiting stronger correlations with WC, BF%, TG, insulin, HOMA2-IR, and smallLDL than MHEI2010, primarily attributed to reduced refined grain serving. Notably, participants with the highest adherence to MHEI2020 scores exhibited significantly reduced odds for elevated TG (AOR 0.44, 95% CI 0.21-0.93, p = 0.030), HOMA2-IR (AOR 0.44, 95% CI 0.21-0.88, p = 0.022), and hsCRP (AOR 0.54, 95% CI 0.31-0.96, p = 0.040, compared to those with the lowest adherence. Each 5-unit increase in MHEI2020 scores reduced odds for elevated BMI (-14%), WC (-9%), LDL-C (-32%), TG (-15%), HOMA2-IR (-9%) and hsCRP (-12%). While MHEI2020 scores demonstrated better calibration with CMR indicators, the overall sub-optimally 'poor' DQ scores of this population call for health promotion activities to target the public to achieve adequate intake of healthful fruits, non-starchy vegetables and wholegrain, and moderate intake of refined grain, added sugar and saturated fat.

DIAGNOSING POVERTY ERADICATION THROUGH LITERACY: ANALYSIS FROM NATIONAL SOCIOECONOMIC SURVEY NORTH SUMATERA PROVINCE

This study supposed to determine the factors that influence the poverty rate in North Sumatra Province. This study used cross sectional data from the North Sumatra Province Socio-Economic Survey 2023. This survey is a survey conducted by the Central Bureau of Statistics (BPS), which aims to collect data on the socio-economic conditions of the community related to the fields of education, health/nutrition, housing, socio-cultural activities, consumption/expenditure and household income, travel, and opinions on household welfare. household. The Socio-Economic Survey of North Sumatra Province 2023 survey data collected by BPS in March 2023 covered 33 regencies/cities in North Sumatra Province with 5000 sample households spread across 325 sub-districts and representing the entire population. The results of this study are literacy has a positive and significant effect on poverty in North Sumatra Province, financial literacy has a positive and significant effect on poverty in North Sumatra Province and age has a positive and significant effect on poverty in North Sumatra Province.
