Beautiful inside and out: Peer characteristics and academic performance

This paper explores the effect of own and peer attractiveness on various measures of academic performance. Using data from the National Longitudinal Survey of Adolescent Health (Add Health), we focus on high school students in the United States and exploit random variation within schools across cohorts in adolescents' physical and personality attractiveness as assessed by the interviewer. We find that for girls only own personality attractiveness boosts academic outcomes. For boys instead, both own physical and personality attractiveness positively affect performance and peer characteristics also matter. An increase in the fraction of physically attractive high school peers decreases boys' academic performance in later years. We show that this effect is driven by less physically mature boys and operates through a decrease in self-confidence.

Bi-directional associations between gender-based harassment at work, psychological treatment and depressive symptoms

IntroductionThe objective of this study was to investigate the bi-directional associations between experienced and witnessed gender-based harassment (GBH) on the one hand, and depressive symptoms and psychological treatment on the other, in an occupational setting. GBH are behaviors that derogate, demean, or humiliate an individual based on his or her gender.MethodsThe analyses were based on data from the Swedish Longitudinal Occupational Survey of Health at 2018 (T1) and 2020 (T2), including 6,679 working participants (60.3% women) with a majority in the age range of 45–64. Using cross-lagged structural equational models, we analyzed experienced and witnessed GBH in relation to depressive symptoms and having received psychological treatment (talked to a counselor or psychological professional) over time.ResultsOur results showed that neither experienced nor witnessed GBH was prospectively associated with depressive symptoms or psychological treatment over two years. Both higher levels of depressive symptoms (β = 0.002, p ≤ 0.001) and having received psychological treatment (β = 0.013, p = 0.027) weakly predicted experiences of GBH over time. Having received psychological treatment was furthermore weakly associated with witnessed GBH (β = 0.019, p = 0.012).DiscussionIn conclusion, the hypothesized associations between exposure to GBH and mental health outcomes were not statistically significant, while a weak reverse association was noted. More research addressing bidirectional associations between GBH and mental health outcomes are needed.

Evidence that highly canalized fetal traits are sensitive to intergenerational effects of maternal developmental nutrition.

Maternal experiences before pregnancy predict birth outcomes, a key indicator of health trajectories, but the timing and pathways for these effects are poorly understood. Here we test the hypothesis that maternal pre-adult growth patterns predict pregnancy glucose and offspring fetal growth in Cebu, Philippines. Using multiple regression and path analysis, gestational age-adjusted birthweight and variables reflecting infancy, childhood, and post-childhood/adolescent weight gain (conditional weights) were used to predict pregnancy HbA1c and offspring birth outcomes among participants in the Cebu Longitudinal Health and Nutrition Survey. Maternal early/mid-childhood weight gain predicted birth weight, length, and head circumference in female offspring. Late-childhood/adolescent weight gain predicted birth length, birth weight, skinfold thickness, and head circumference in female offspring, and head circumference in male offspring. Pregnancy HbA1c did not mediate relationships between maternal growth and birth size parameters. In Cebu, maternal growth patterns throughout infancy, childhood, and adolescence predict fetal growth via a pathway independent of circulating glucose, with stronger impacts on female than male offspring, consistent with a role of developmental nutrition on offspring fetal growth. Notably, the strength of relationships followed a pattern opposite to what occurs in response to acute pregnancy stress, with strongest effects on head circumference and birth length and weakest on skinfolds. We speculate that developmental sensitivities are reversed for stable, long-term nutritional cues that reflect average local environments. These findings are relevant to public health and life-history theory as further evidence of developmental influences on health and resource allocation across the life course.

Socioeconomic status is negatively associated with immunosenescence but positively associated with inflammation among middle-aged women in Cebu, Philippines

BackgroundSocioeconomic status (SES) gradients in health are well-documented, and while biological pathways are incompletely understood, chronic inflammation and accelerated immune aging (immunosenescence) among lower SES individuals have been implicated. However, previous findings have come from samples in higher income countries, and it is unclear how generalizable they are to lower- and middle-income countries (LMIC) with different infectious exposures and where adiposity—an important contributor to chronic inflammation—might show different SES patterning. To address this gap, we explored associations between SES and inflammation and immunosenescence in a sample of women in Cebu, Philippines. MethodsData came from the mothers of the Cebu Longitudinal Health and Nutrition Survey birth cohort (mean age: 47.7, range: 35–69 years). SES was measured as a combination of annual household income, education level, and assets. Chronic inflammation was measured using C-reactive protein (CRP) in plasma samples from 1,834 women. Immunosenescence was measured by the abundance of exhausted CD8T (CD8 + CD28-CD45RA-) and naïve CD8T and CD4T cells, estimated from DNA methylation in whole blood in a random subsample of 1,028. Possible mediators included waist circumference and a collection of proxy measures of pathogen exposure. ResultsSES was negatively associated with the measures of immunosenescence, with slight evidence for mediation by a proxy measure for pathogen exposure from the household’s drinking water source. In contrast, SES was positively associated with CRP, which was explained by the positive association with waist circumference. ConclusionsSimilar to higher income populations, in Cebu there is an SES-gradient in pathogen exposures and immunosenescence. However, lifestyle changes occurring more rapidly among higher SES individuals is contributing to a positive association between SES and adiposity and inflammation. Our results suggest more studies are needed to clarify the relationship between SES and inflammation and immunosenescence across LMIC.

Uncovering Polysubstance Use Patterns in Canadian Youth with Machine Learning on Longitudinal COMPASS Data

AbstractUnderstanding polysubstance use (PSU) patterns and their associated factors among youth is crucial for addressing the complex issue of substance use in this population. This study aims to investigate PSU patterns in a large sample of Canadian youth and explore associated factors using data from COMPASS, a longitudinal health survey of Canadian secondary school students. The study sample consisted of 8824 students from grades 9 and 10 at baseline in 2016/17, followed over 3 years until 2018/19. Leveraging machine learning methods, especially the least absolute shrinkage and selection operator (LASSO) and multivariate latent Markov models, we conducted a comprehensive examination of PSU patterns. Our analyses revealed distinct PSU patterns among Canadian youth, including no-use (C1), alcohol-only (C2), concurrent use of e-cigarettes and alcohol (C3), and poly-use (C4). C1 showed the highest prevalence (60.5%) in 2016/17, declining by 2.4 times over 3 years, while C3 became the dominant pattern (32.5%) in 2018/19. The prevalence of C3 and C4 increased by 2.3 and 4.4 times, respectively, indicating a growing trend of dual and multiple substance use. Risk factors associated with PSU patterns included truancy (ORC2 = 1.67, 95 % CI [1.55, 1.79]; ORC3 = 1.92, 95 % CI [1.80, 2.04]; ORC4 = 2.79, 95 % CI [2.64, 2.94]), having more smoking friends, more weekly allowance, elevated BMI, being older, and attending schools unsupportive in quitting drugs/alcohol. In contrast, not gambling online (ORC2 = 0.22, 95 % CI [−0.16, 0.58]; ORC3 = 0.14, 95 % CI [-0.24, 0.52]; ORC4 = 0.08, 95 % CI [−0.47, 0.63]), eating breakfast, residing in urban areas, and having higher school connectedness were protective factors against a higher-use pattern. This study provides insights for policymakers, educators, and health professionals to design targeted and evidence-based interventions, addressing youth substance use challenges through a comprehensive examination of PSU patterns and influential factors impacting substance use behaviors.

Effects of Excluding Those Who Report Having "Syndomitis" or "Chekalism" on Data Quality: Longitudinal Health Survey of a Sample From Amazon's Mechanical Turk.

Researchers have implemented multiple approaches to increase data quality from existing web-based panels such as Amazon's Mechanical Turk (MTurk). This study extends prior work by examining improvements in data quality and effects on mean estimates of health status by excluding respondents who endorse 1 or both of 2 fake health conditions ("Syndomitis" and "Chekalism"). Survey data were collected in 2021 at baseline and 3 months later from MTurk study participants, aged 18 years or older, with an internet protocol address in the United States, and who had completed a minimum of 500 previous MTurk "human intelligence tasks." We included questions about demographic characteristics, health conditions (including the 2 fake conditions), and the Patient Reported Outcomes Measurement Information System (PROMIS)-29+2 (version 2.1) preference-based score survey. The 3-month follow-up survey was only administered to those who reported having back pain and did not endorse a fake condition at baseline. In total, 15% (996/6832) of the sample endorsed at least 1 of the 2 fake conditions at baseline. Those who endorsed a fake condition at baseline were more likely to identify as male, non-White, younger, report more health conditions, and take longer to complete the survey than those who did not endorse a fake condition. They also had substantially lower internal consistency reliability on the PROMIS-29+2 scales than those who did not endorse a fake condition: physical function (0.69 vs 0.89), pain interference (0.80 vs 0.94), fatigue (0.80 vs 0.92), depression (0.78 vs 0.92), anxiety (0.78 vs 0.90), sleep disturbance (-0.27 vs 0.84), ability to participate in social roles and activities (0.77 vs 0.92), and cognitive function (0.65 vs 0.77). The lack of reliability of the sleep disturbance scale for those endorsing a fake condition was because it includes both positively and negatively worded items. Those who reported a fake condition reported significantly worse self-reported health scores (except for sleep disturbance) than those who did not endorse a fake condition. Excluding those who endorsed a fake condition improved the overall mean PROMIS-29+2 (version 2.1) T-scores by 1-2 points and the PROMIS preference-based score by 0.04. Although they did not endorse a fake condition at baseline, 6% (n=59) of them endorsed at least 1 of them on the 3-month survey and they had lower PROMIS-29+2 score internal consistency reliability and worse mean scores on the 3-month survey than those who did not report having a fake condition. Based on these results, we estimate that 25% (1708/6832) of the MTurk respondents provided careless or dishonest responses. This study provides evidence that asking about fake health conditions can help to screen out respondents who may be dishonest or careless. We recommend this approach be used routinely in samples of members of MTurk.

Green sleep: Immediate residential greenspace and access to larger green areas are associated with better sleep quality, in a longitudinal population-based cohort

ObjectiveSleep is pivotal to health, wellbeing and functioning in daily life, but sleep difficulties are common and may be affected by modifiable qualities in the residential surrounding environment, in terms of greenspace. However, population-based studies on individual-level greenspace and sleep are limited. The objective of the current study was thus to investigate prospective associations between fine-grained individual-level residential greenspace and sleep, and moderating effects of life style (physical activity, work status) and sex, in a nationwide population-based Swedish cohort. MethodsParticipants of the Swedish Longitudinal Occupational Survey of Health (SLOSH)—a population-based sample of adults in Sweden—were studied during 2014–2018 (19,375 individuals; 43,062 observations). Residential greenspace land cover, and coherent green area size, were assessed via high resolution geographic information systems, at 50, 100, 300, 500 and 1000 m buffers around residences. Prospective greenspace and sleep associations were assessed via multilevel general linear models, adjusting for demographic, socioeconomic (individual and neighborhood), life style and urban factors. ResultsHigher greenspace availability in the immediate residential surroundings (50 m and 100 m buffer zones) was associated with less sleep difficulties, even after adjustment for confounders. Greenspace effects were generally greater among non-working individuals. Among the physically active, and among non-working, greenspace and green area size further away from home (300, 500 and 1000 m, i.e. dependent on mobility) were also associated with less sleep difficulties. ConclusionsResidential greenspace in the immediate residential surroundings is associated with significantly less sleep difficulties. Greenspace further away from home was associated with better sleep especially among the physically active, and non-working individuals. The results highlight the importance of greenspace in the immediate residential-surrounding environment for sleep, and the need to integrate health and environmental policies, urban planning and greening.

Organizational injustice and sickness absence: The moderating role of locked-in status

Organizational injustice is known to negatively affect employees’ health and to increase the risk for sickness absence. The negative health effects are also known to be more pronounced in uncontrollable, strain increasing, situations at the workplace. This study tests whether locked-in status, i.e., being stuck in a non-preferred workplace, modifies the associations between injustice perceptions and frequent (≥2 times/yr) and long (≥ 8 days/yr) sickness absence. The sample contained 2631 permanent employees from the Swedish Longitudinal Occupational Survey of Health in 2018 and 2020. Multigroup structural equation modelling was used to compare the proposed relationships between employees who are locked-in in their workplace and employees who are not. We found a positive association between higher overall organizational injustice and long sickness absence two years later, with the association being stronger for the locked-in group. Also, higher injustice was associated with more frequent sickness absence, but only for those not being locked-in.Employees being locked-in seem to have higher risk of long-term sickness absence which might indicate more serious health problems. Employees not being locked-in more often take short sickness absence, which could indicate a coping behaviour to handle high strain. This study adds knowledge to the role of locked-in status as a moderator in the much-studied relationship between organizational justice and health as well as to the multiple reasons underlying sickness absence.

Workplace Psychosocial Resources and Risk of Sleep Disturbances Among Employees

Workplace psychosocial resources naturally tend to cluster in some work teams. To inform work-related sleep health promotion interventions, it is important to determine the associations between clustering of workplace resources and sleep disturbances when some resources are high while others are low and to mimic an actual intervention using observational data. To examine whether clustering of and changes in workplace psychosocial resources are associated with sleep disturbances among workers. This population-based cohort study used data from the Swedish Longitudinal Occupational Survey of Health (2012-2018), the Work Environment and Health in Denmark study (2012-2018), and the Finnish Public Sector Study (2008-2014), collected biennially. Statistical analysis was conducted from November 2020 to June 2022. Questionnaires were distributed measuring leadership quality and procedural justice (ie, vertical resources) as well as collaboration culture and coworker support (ie, horizontal resources). Resources were divided into clusters of general low, intermediate vertical and low horizontal, low vertical and high horizontal, intermediate vertical and high horizontal, and general high. Odds ratios (ORs) and 95% CIs were reported from logistic regression models for the associations between the clustering of resources and concurrent and long-term sleep disturbances. Sleep disturbances were measured by self-administered questionnaires. The study identified 114 971 participants with 219 982 participant-observations (151 021 [69%] women; mean [SD] age, 48 [10] years). Compared with participants with general low resources, other groups showed a lower prevalence of sleep disturbances, with the lowest observed in the general high group concurrently (OR, 0.38; 95% CI, 0.37-0.40) and longitudinally after 6 years (OR, 0.52; 95% CI, 0.48-0.57). Approximately half of the participants (27 167 participants [53%]) experienced changes in resource clusters within 2 years. Improvements in vertical or horizontal dimensions were associated with reduced odds of persistent sleep disturbances, and the lowest odds of sleep disturbances was found in the group with improvements in both vertical and horizontal dimensions (OR, 0.53; 95% CI, 0.46-0.62). A corresponding dose-response association with sleep disturbances was observed for decline in resources (eg, decline in both dimensions: OR, 1.74; 95% CI, 1.54-1.97). In this cohort study of workplace psychosocial resources and sleep disturbances, clustering of favorable resources was associated with a lower risk of sleep disturbances.

Job loss and job instability during the COVID-19 pandemic and the risk of depression and anxiety among Swedish employees

The COVID-19 pandemic led to permanent and temporary job losses but the mental health consequences of different types of employment transitions are not well-understood. In particular, knowledge is scarce concerning furloughs, which was a common job protection strategy in many high- and upper middle-income countries during this crisis. This study focuses on how different types of job instability and job loss during the pandemic influences depression and anxiety in the context of Sweden.A subset of participants from the Swedish Longitudinal Occupational Survey of Health were contacted in February 2021 and again in February 2022. A total of 1558 individuals participated in either or both waves and worked before the pandemic. We examined whether i) workplace downsizing, ii) furlough, or iii) unemployment/job loss were associated with depression and anxiety over this one-year period during the pandemic. Logistic regression models with cluster-robust standard errors were estimated, adjusting for sociodemographic factors and prior mental health problems. Effect modification by sex and prior mental health problems was also examined.In comparison to stable employment, being furloughed was unrelated to mental health, while experiencing workplace downsizing during the pandemic was associated with an increased risk of anxiety (adjusted Odds Ratio (OR) = 2.09, 95% Confidence interval (CI) = 1.08–4.05). Job loss/unemployment increased the risk of depression (OR = 1.91, 95% CI = 1.02–3.57) compared to being stably employed, but the risk estimate crossed unity when considering prior mental health status. No effect modification by sex or by prior mental health problems was found.This study found that while job loss and downsizing during the COVID-19 pandemic were associated with depression and anxiety, respectively, being furloughed was not. These findings thus suggest that job retention schemes in the form of short-time work allowances, as implemented in Sweden during the COVID-19 pandemic, may prevent mental health problems among employees during economic crises.

Longitudinal health survey of women from Venezuela in Colombia (ELSA-VENCOL): First report.

Colombia is currently the world's main recipient country for Venezuelan migrants, and women represent a high proportion of them. This article presents the first report of a cohort of Venezuelan migrant women entering Colombia through Cúcuta and its metropolitan area. The study aimed to describe the health status and access to healthcare services among Venezuelan migrant women in Colombia with irregular migration status, and to analyze changes in those conditions at a one-month follow-up. We carried out a longitudinal cohort study of Venezuelan migrant women, 18 to 45 years, who entered Colombia with an irregular migration status. Study participants were recruited in Cúcuta and its metropolitan area. At baseline, we administered a structured questionnaire including sociodemographic characteristics, migration history, health history, access to health services, sexual and reproductive health, practice of early detection of cervical cancer and breast cancer, food insecurity, and depressive symptoms. The women were again contacted by phone one month later, between March and July 2021, and a second questionnaire was applied. A total of 2,298 women were included in the baseline measurement and 56.4% could be contacted again at the one-month follow-up. At the baseline, 23.0% of the participants reported a self-perceived health problem or condition in the past month and 29.5% in the past 6 months, and 14.5% evaluated their health as fair or poor. A significant increase was found in the percentage of women who reported a self-perceived health problem during the past month (from 23.1% to 31.4%; p<0.01); as well as in the share who reported moderate, severe, or extreme difficulty working or performing daily chores (from 5.5% to 11.0%; p = 0.03) and who rated their health as fair (from 13.0% to 31.2%; p<0.01). Meanwhile, the percentage of women with depressive symptoms decreased from 80.5% to 71.2% (p<0.01). This report presents initial information on the health status of Venezuelan migrant women in Colombia, and is a starting point for further longer longitudinal follow-ups to assess changes over time in health conditions.

Associations between COVID-19-related changes in the psychosocial work environment and mental health.

Individuals' lives have been substantially affected by the COVID-19 pandemic. We aimed to describe changes in psychosocial work environment and mental health and to investigate associations between job insecurity and mental ill-health in relation to changes in other psychosocial work factors, loneliness and financial worries. A sub-sample of individuals from the eighth Swedish Longitudinal Occupational Survey of Health answered a web-based survey in early 2021 about current and pandemic-related changes in health, health behaviours, work and private life. We investigated participants working before the pandemic (N=1231) in relation to standardised measures on depression, anxiety and loneliness, together with psychosocial work factors, in descriptive and logistic regression analyses. While 9% reached the clinical threshold for depression and 6% for anxiety, more than a third felt more worried, lonelier or in a low mood since the start of the pandemic. Two per cent had been dismissed from their jobs, but 16% experienced workplace downsizings. Conditioning on socio-demographic factors and prior mental-health problems, the 8% experiencing reduced job security during the pandemic had a higher risk of anxiety, but not of depression, compared to employees with unaltered or increased job security. Loneliness and other psychosocial work factors explained more of the association than objective measures of job insecurity and financial worries. Reduced job security during the COVID-19 pandemic seems to have increased the risk of anxiety among individuals with a strong labour market attachment, primarily via loneliness and other psychosocial work factors. This illustrates the potentially far-reaching effects of the pandemic on mental health in the working population.

Are Trajectories of Preferred Retirement Ages Associated with Health, Work Ability and Effort–Reward Imbalance at Work? Findings from a 6-Year Swedish Longitudinal Study

AbstractPreferred retirement age (PRA) is one key dimension when studying retirement decision-making. However, little is known concerning how PRA develops over the late career years. This study used a person-centered approach to longitudinally investigate trajectories of PRA and how they differ in self-rated health, perceived work ability, and effort–reward imbalance (ERI) at baseline levels and over 6 years. The study used data from four waves (2010, 2012, 2014, and 2016) of the Swedish Longitudinal Occupational Survey of Health. The sample consisted of 1,510 individuals aged 50–55 in 2010, who answered to the questionnaire for those in paid work (including self-employment) at the baseline and at least one of the following waves. Results from the latent class growth curve modeling show both within- and between-person variability in PRA over the 6-year span. We found four distinct trajectories, which differed both at the baseline levels and in the patterns of change in PRA: “C1: normative, relatively stable PRA” (42% of all participants); “C2: considerably early, increasing PRA” (6% of the participants); “C3: late, relatively stable PRA” (4% of the participants); and “C4: early, increasing PRA” (49% of the participants). Participants revealed a clear preference for retirement before the age of 65. Trajectories comprising earlier PRA showed poorer self-rated health, poorer work ability, and higher levels of ERI at the baseline and over time. The findings reinforce the importance of healthy work environments that promote work ability and facilitate a balance between efforts and rewards for encouraging longer working lives.

Deployment-related concussion and long-term health-relatedquality of life among US military personnel.

To examine the relationship between deployment-related concussion and long-term health-related quality of life (HRQoL) among injured US military personnel. The study sample included 810 service members with deployment-related injuries between 2008 and 2012 who responded to a web-based longitudinal health survey. Participants were categorized into three injury groups: concussion with loss of consciousness (LOC; n = 247), concussion without LOC (n = 317), or no concussion (n = 246). HRQoL was measured using the 36-Item Short Form Health Survey physical and mental component summary (PCS and MCS) scores. Current post-traumatic stress disorder (PTSD) and depression symptoms were examined. Multivariable linear regression models assessed the effects of concussion on PCS and MCS scores, while controlling for covariates. A lower PCS score was observed in participants with concussion with LOC (B = - 2.65, p = 0.003) compared with those with no history of concussion. Symptoms of PTSD (PCS: B = - 4.84, p < 0.001; MCS: B = - 10.53, p < 0.001) and depression (PCS: B = - 2.85, p < 0.001; MCS: B = - 10.24, p < 0.001) were the strongest statistically significant predictors of lower HRQoL. Concussion with LOC was significantly associated with lower HRQoL in the physical domain. These findings affirm that concussion management should integrate physical and psychological care to improve long-term HRQoL and warrant a more detailed examination of causal and mediating mechanisms. Future research should continue to incorporate patient-reported outcomes and long-term follow-up of military service members to further define the lifelong impact of deployment-related concussion.

Prenatal household size and composition are associated with infant fecal bacterial diversity in Cebu, Philippines.

The gut microbiome (GM) connects physical and social environments to infant health. Since the infant GM affects immune system development, there is interest in understanding how infants acquire microbes from mothers and other household members. As a part of the Cebu Longitudinal Health and Nutrition Survey (CLHNS), we paired fecal samples (proxy for the GM) collected from infants living in Metro Cebu, Philippines at 2 weeks (N=39) and 6 months (N=36) with maternal interviews about prenatal household composition. We hypothesized that relationships between prenatal household size and composition and infant GM bacterial diversity (as measured in fecal samples) would vary by infant age, as well as by household member age and sex. We also hypothesized that infant GM bacterial abundances would differ by prenatal household size and composition. Data from 16 S rRNA bacterial gene sequencing show that prenatal household size was the most precise estimator of infant GM bacterial diversity, and that the direction of the association between this variable and infant GM bacterial diversity changed between the two time points. The abundances of bacterial families in the infant GM varied by prenatal household variables. Results highlight the contributions of various household sources to the bacterial diversity of the infant GM, and suggest that prenatal household size is a useful measure for estimating infant GM bacterial diversity in this cohort. Future research should measure the effect of specific sources of household bacterial exposures, including social interactions with caregivers, on the infant GM.

Prolonging working life among blue-collar workers: The buffering effect of psychosocial job resources on the association between physically demanding and hazardous work and retirement timing

The need to delay retirement timing has been acknowledged in Western countries due to demographic ageing. The aim of the present study was to examine the buffering effects of job resources (decision authority, social support, work-time control, and rewards) on the association of exposures to physically demanding work tasks and physically hazardous work environment with non-disability retirement timing. Results from discrete-time event history analyses, in a sample of blue-collar workers (n = 1741; 2792 observations) from the nationwide longitudinal Swedish Longitudinal Occupational Survey of Health (SLOSH), supported that decision authority and social support may buffer the negative impact of heavy physical demands on working longer (continuing working vs retiring). Stratified analyses by gender showed that the buffering effect of decision authority remained statistically significant for men, while that of social support remained statistically significant for women. Moreover, an age effect was displayed, such that a buffering effect of social support on the association of heavy physical demands and high physical hazards with working longer were found among older men (≥64 years), but not younger (59–63 years). The findings suggest that heavy physical demands should be reduced, however, when not feasible physical demands should be accompanied by social support at work for delaying retirement.

Nuances in the effect of types of intimate partner violence on aspects of child development: Evidence from the Philippines

BackgroundMost studies on the effect of intimate partner violence (IPV) do not distinguish between the effects of the different types of IPVs on the various aspects of child development. ObjectiveThis study explores the effect of multiple dimensions of IPV, specifically physical violence, controlling behavior, and emotional abuse, on children's physical and cognitive development. Participants and settingThe study uses data from the Cebu Longitudinal Health and Nutritional Survey (CLHNS). The study uses a final sample of n = 1506 index children in Cebu, Philippines. MethodsWe use information pertaining to: (1) presence of IPV in the household, (2) demographic characteristics, (3) mother's status and autonomy, (4) anthropometric data, and (5) children's scores on mathematics, English, language, and nonverbal reasoning tests. We employ a Propensity Score Matching (PSM) technique to analyze the effect of IPV on child development outcomes, conditional on observed characteristics. ResultsMaternal exposure to physical violence significantly reduces child’s body mass index (BMI) (ATE: −0.344, p ≤ 0.05). On the other hand, mother's vulnerability to controlling behavior decreases children's test scores in mathematics (ATE: −3.346, p ≤ 0.01), English (ATE: −2.289, p ≤ 0.01), and nonverbal reasoning (ATE: −2.103, p ≤ 0.01). We do not find a significant link between emotional abuse and height, body mass index, and test scores. ConclusionsOur study shows that the deleterious effect of IPV on child development is IPV-specific. Exposure to physical violence tends to affect children's physical development while cognitive abilities are negatively associated with exposure to controlling behavior. These results suggest different types of ex-post interventions on both children and mothers to ensure their physical and mental well-being.

Association of social participation and psychological resilience with adverse cognitive outcomes among older Chinese adults: A national longitudinal study

BackgroundLimited epidemiological evidence exists regarding the association of social participation and psychological resilience with cognitive health. This study aimed to comprehensively investigate the effects of social participation and psychological resilience on adverse cognitive outcomes among older adults in China. MethodsWe used two waves (2011 and 2014) of data from the Chinese Longitudinal Survey of Health and Longevity (CLHLS), and 9765 respondents were eligible for the subsequent screening for the present prospective analysis. The Cox proportional hazards model was utilized to examine the association of social participation and psychological resilience with cognitive impairment, cognitive decline and greater cognitive decline. The restricted cubic spline plots were applied to clarify the dose–response relationships between them. ResultsCompared to those with low social participation, participants with high social participation had a lower hazard ratio (HR) of 0.72 (95 % confidence interval [CI]: 0.59–0.89) for cognitive impairment, 0.85 (95 % CI: 0.76–0.94) for cognitive decline and 0.78 (95 % CI: 0.67–0.90) for greater cognitive decline. Participants with high psychological resilience had an HR of 0.77 (95 % CI: 0.63–0.95) for cognitive impairment 0.85 (95 % CI: 0.76–0.94) for cognitive decline and 0.85 (95 % CI: 0.73–0.98) for greater cognitive decline compared with those with low psychological resilience. Similar effects were observed for social participation score and psychological resilience score. The dose–response analysis also showed that the risk of adverse cognitive outcomes decreased gradually with increasing social participation scores and psychological resilience scores. Additionally, the multiplicative interaction between social participation and psychological resilience was not significant. LimitationAll information was collected by self-report, which may lead to biases in the process of information collection. ConclusionIn this study, social participation and psychological resilience were independently associated with a lower risk of adverse cognitive outcomes, and therefore both need to be considered as broader measures to preserve cognitive health among older Chinese adults.

Minimum wages and mental health: Evidence from Canada

International evidence on the effect of minimum wages on mental health has been mixed. Estimation has used different types of variation in the minimum wage. In some countries such as the UK, the minimum wage is set nationally. In the United States, it is largely set subnationally. The resulting across state and time variation has recently been used to estimate that minimum wage increases have a positive effect on mental health. We exploit similar and substantial subnational level variation for Canada, using a longitudinal health survey panel available from 1994 to 2011. Using difference-in-difference and triple difference methods with individual fixed effects, we find that minimum wage increases are associated with modest reductions in distress and depression symptoms, largely for males.

Influences of temperature and humidity on cardiovascular disease among adults 65 years and older in China.

The burden of cardiovascular disease (CVD) on the current aging society in China is substantial. Climate change, including extreme temperatures and humidity, has a detrimental influence on health. However, epidemiological studies have been unable to fully identify the association between climate change and CVD among older adults. Therefore, we investigated the associations between temperature and relative humidity and CVD among older adults in China. We used cohort data from the China Longitudinal Health and Longevity Survey (CLHLS) conducted in 2002, 2005, 2008, 2011, 2014, and 2018. A total of 39,278 Chinese adults 65 years and older participated in the analyses. The average annual temperatures and relative humidity during 2001 and 2017 (before the survey year) at the city level in China were used as the exposure measures. We selected patients with hypertension, heart disease, and stroke to create a sample of CVD patients. The associations between temperature and relative humidity and CVD were analyzed using the generalized estimation equation (GEE) model. Covariates included sociodemographic factors, health status, lifestyle, and cognitive function. The average annual temperature was negatively correlated with the prevalence of CVD. Every 1°C increase in the average annual temperature reduced the rates of hypertension by 3% [odds ratio (OR): 0.97; 95% confidence interval (CI): 0.96-0.97], heart disease by 6% (OR: 0.94; 95% CI: 0.92-0.95), and stroke by 5% (OR: 0.95; 95% CI: 0.94-0.97). The results of the analyses stratified by sex, urban/rural residence, and educational level were robust. The average annual relative humidity was inversely associated with the likelihood of CVD among older adults. Every 1% increase in the average annual relative humidity reduced the rates of hypertension by 0.4% (OR: 0.996; 95% CI: 0.99-1.00), heart disease by 0.6% (OR: 0.994; 95% CI: 0.99-1.00), and stroke by 0.08% (OR: 0.992; 95% CI: 0.98-1.00). However, the effects were more obvious with higher humidity levels (>70). Our findings suggest that higher temperatures and relative humidity may reduce the risk of CVD among older adults.
