Undernutrition, cognitive decline and dementia: The collaborative PROMED-COG pooled cohorts study

Background & aimsUndernutrition may negatively impact cognitive function, but evidence of this relationship is not yet consolidated. Under the “PROtein enriched MEDiterranean diet to combat undernutrition and promote healthy neuroCOGnitive ageing” (PROMED-COG) project, we evaluated the association between undernutrition, and cognitive decline and incident dementia in older adults. MethodsRetrospective data harmonization was performed on three Italian population-based studies: the Italian Longitudinal Study of Ageing (ILSA), the Progetto Veneto Anziani (Pro.V.A.), and the Bollate Eye Study-Follow-Up (BEST-FU). The associations between undernutrition, operationalized using the Global Leadership Initiative on Malnutrition (GLIM) criteria, and decline on the Mini-Mental State Examination (MMSE) or dementia incidence follow-up were evaluated with Cox proportional hazard regression models. ResultsThe pooled cohort comprised 9071 individuals (52% females) aged between 42 and 101 years. The prevalence of undernutrition at the baseline was 14.3%, significantly higher among females (15.4% vs 13%) and in older age, ranging from 3.5% in those aged <60 years to 28.8% in those 85+ years. Undernutrition was associated with both cognitive decline over a median 8.3-year follow-up (Hazard Ratio (HR) 1.20, 95% Confidence Interval (CI) 1.02–1.41, p = 0.028) and incidence of dementia over a median 8.6-year follow-up (HR = 1.57, 95%CI 1.01–2.43, p = 0.046). For cognitive decline, the association with undernutrition was more marked in males than females (HR = 1.36, 95%CI 1.05–1.77, p = 0.019 vs HR = 1.10, 95% CI 0.89–1.36, p = 0.375). ConclusionUndernutrition is prevalent among older people and is associated with an increased risk of experiencing cognitive decline and dementia. The prevention and early identification of undernutrition could be an important nonpharmacologic strategy to counteract neurodegeneration.

Development and predictors of reading skills in a 5‐year Italian longitudinal study

Self-care behaviours and their determinants in people affected by coronary heart disease.

To describe self-care in Italian adults with coronary heart disease and to identify sociodemographic and clinical determinants of self-care. This is a cross-sectional analysis of data from the Italian multicentre longitudinal study. We used the follow instruments: Self-Care of coronary heart disease inventory, Self-care Self Efficacy Scale, Charlson Comorbidity Index and Sociodemographic questionnaire. Descriptive statistics including absolute numbers, percentages, means and standard deviations were used to describe the sociodemographic and clinical characteristics of the sample, and the items. A structural equation model was fitted to understand sociodemographic and clinical variables associated with self-care, and possible effects mediated by self-efficacy. We enrolled 427 patients. Self-care maintenance, monitoring, management and self-care self-efficacy means scores were 58.27 (SD = 20.07), 48.53 (SD = 26.97), 65.34 (SD = 22.85) and 77.16 (SD = 20.76), respectively. Except for the self-care self-efficacy scale, all the scores lay below the cut off 70 for adequacy. Older age, higher comorbidities, a higher number of stents placed, and the presence of a caregiver predicted poor self-care. Self-care in Italian CHD populations is poor. Several associations were found between the dimensions of self-care and sociodemographic factors. Implications for the profession these findings are important for health care providers to plan interventions to improve self-care behaviour. The study addressed self-care behaviours of coronary heart disease patients. Self-care was poor in this population; several associations were found between the dimensions of self-care and sociodemographic and clinical determinants. Our results can be used to support health professionals in planning interventions to improve specific self-care domains. STROBE checklist was followed.

Baseline antipsychotic prescription and short-term outcome indicators in individuals at clinical high-risk for psychosis: Findings from an Italian longitudinal study

IntroductionThe prognostic prediction of outcomes in individuals at clinical high-risk for psychosis (CHR-P) is still a significant clinical challenge. Among multiple baseline variables of risk calculator models, the role of ongoing pharmacological medications has been partially neglected, despite meta-analytical evidence of higher risk of psychosis transition associated with baseline prescription exposure to antipsychotics (AP) in CHR-P individuals. In particular, baseline AP exposure in CHR-P individuals may be considered as a functional equivalent of the psychometric transition to psychosis, as already postulated in the original ‘Ultra High-Risk’ model.ObjectivesThe main aim of the current study was to test the hypothesis that ongoing AP need at baseline indexes a subgroup of CHR-P individuals with more severe psychopathology and worse prognostic trajectories along a 1-year follow-up period.MethodsThis research was settled within the ‘Parma At-Risk Mental States’ program. Baseline and 1-year follow-up assessment included the Positive And Negative Syndrome Scale (PANSS) and the Global Assessment of Functioning (GAF). CHR-P individuals who were taking AP medications at entry were included in the CHR-P-AP+ subgroup. The remaining participants were grouped as CHR-P-AP-. The acquisition of drug and outcome information was collected both at baseline and across the follow-up period. Finally, logistic regression analyses with dichotomized 1-year outcome parameters (previously showing statistically significant differences in inter-group comparisons) as dependent measures and sociodemographic and clinical characteristics as independent variables were also performed.ResultsHundred and seventy-eight CHR-P individuals (aged 12–25 years) were enrolled (91 CHR-P-AP+, 87 CHR-P-AP-). Compared to CHR-P AP-, CHR-P AP+ individuals had older age, greater baseline PANSS ‘Positive Symptoms’ and ‘Negative Symptoms’ factor subscores and a lower GAF score. At the end of our follow-up, CHR-P-AP+ subjects showed higher rates of psychosis transition, new hospitalizations and urgent/non-planned visits compared to CHRP- AP- individuals.ConclusionsThe current study suggests that AP need is a significant prognostic variable in cohorts of CHR-P individuals and should be included in the current risk calculators. In particular, the results of this study conducted in a realworld clinical setting indicate that the rate of CHR-P individuals who were already exposed to AP at the time of CHR-P status ascription was higher than those reported in recent meta-analyses on this topic. Moreover, our findings confirm that baseline AP prescription appears to increase psychotic transition risk.Disclosure of InterestNone Declared

The impact of cognitive function deficits and their recovery on functional outcome in subjects affected by ischemic subacute stroke: results from the Italian multicenter longitudinal study CogniReMo.

The recovery of independence in activities of daily living is a fundamental goal of rehabilitation programs in subjects affected by subacute stroke. Rehabilitation is focused both on motor and cognitive aspects, and some evidence has reported cognitive deficits as prognostic factors of motor recovery. However, rehabilitation is a dynamic process during which executive functions and motor functions should be improved. The aim of the study is to evaluate the relationships between impairments in cognitive functions and recovery of functional independence in stroke patients during the subacute phase. Multicenter observational study. Intensive rehabilitation units. A sample of 319 stroke patients in subacute phase (70.6±11.6 years, 40.4% females), consecutively admitted from November 2019 to July 2021 at sixteen rehabilitation centers were enrolled in this observational, prospective and multicentric study with longitudinal assessments. Cognitive and functional assessments were performed at hospital admission and discharge, including Oxford Cognitive Screen, modified Barthel Index, Functional Independent Measure, Fugl-Meyer assessment scale and National Institutes of Health Stroke Scale. A regression analysis identified five predictors (out of about 200 tested variables) of functional recovery related to four aspects assessed at admission: functional status (P<0.001), lower limb functioning (P=0.002), attention (P=0.011), and executive functions (P=0.017). Furthermore, patients who recovered deficits in executive functions had the same recovery of those without deficits, whereas those who maintained deficits had a smaller recovery (P=0.019). The relationship between cognitive and motor deficits is increasingly highlighted and the recovery of executive functions deficits seems to contribute to motor recovery. Our results suggest that the recovery of executive functions may promote the recovery of the functional outcome of the patient with subacute stroke. Future treatment protocols may benefit from paying more attention to the recovery of executive functions.

Pattern of access, early predictors of use, and treatment effectiveness of a psychological counselling service for medical students: an Italian longitudinal study

ABSTRACT Psychological counselling represents sensitive frontline services for the detection and treatment of early signs of distress in students. This study aims to assess psychological distress in medical students at the beginning of their academic career and the access rate to a counselling service during medical school. Predictors of access to the service and the effectiveness of the service were also explored. Distress and emotional dysregulation were measured in three consecutive cohorts of first-year students (n = 385, 53% female). Students accessing the counselling service at any time during the 6 years of medical school all completed the same baseline measurements and a pre/post assessment of the intervention. Nearly one-third of first-year students reported levels of distress above the clinical cutoff. The access rate to the counselling service was 13.9%. Only 21% of the students with clinical levels of distress contacted the counselling service. Living alone and having high distress at the beginning of the medical course were the main predictors of access to the service. Students reported a significant reduction of distress and dysregulation after counselling interventions. More efforts are needed to develop effective tools for identifying and tracking medical students in psychological hardship and to increase their willingness to attend the counselling services.

Modifications in Electrocardiographic and Vectordardiographic Morphological Parameters in Elderly Males as Result of Cardiovascular Diseases and Diabetes Mellitus.

Morphological electrocardiographic and vectorcardiographic features have been used in the detection of cardiovascular diseases and prediction of the risk of cardiac death for a long time. The objective of the current study was to investigate the morphological electrocardiographic modifications in the presence of cardiovascular diseases and diabetes mellitus in an elderly male population, most of them with multiple comorbidities. A database of ECG recordings from the Italian Longitudinal Study on Aging (ILSA-CNR), created to evaluate physiological and pathological modifications related to aging, was considered. The study examined a group of 1109 males with full clinical documentation aged 65-84 years. A healthy control group (219 individuals) was compared to the groups of diabetes mellitus (130), angina pectoris (99), hypertension (607), myocardial infarction (160), arrhythmia (386), congestive heart failure (73), and peripheral artery disease (95). Twenty-one electrocardiographic features were explored, and the effects of cardiovascular diseases and diabetes on these parameters were analyzed. The three-years mortality index was derived and analyzed. Myocardial infarction and arrhythmia were the diagnostic groups that showed a significant deviation of 11 electrocardiographic parameters compared to the healthy group, followed by hypertension and congestive heart failure (10), angina pectoris (9), and diabetes mellitus and peripheral artery disease (8). In particular, a set of three parameters (QRS and T roundness and principal component analysis of T wave) increased significantly, whereas four parameters (T amplitude, T maximal vector, T vector ratio, and T wave area dispersion) decreased significantly in all cardiovascular diseases and diabetes mellitus with respect to healthy group. The QRS parameters show a more specific discrimination with a single disease or a group of diseases, whereas the T-wave features seems to be influenced by all the pathological conditions. The present investigation of disease-related electrocardiographic parameters changes can be used in assessing the risk analysis of cardiac death, and gender medicine.

The North Italian Longitudinal Study Assessing the Mental Health Effects of SARS-CoV-2 Pandemic on Health Care Workers-Part I: Study Design and Psychometric Structural Validity of the HSE Indicator Tool and Work Satisfaction Scale.

Literature on the impact of the SARS-CoV-2 pandemic on the mental health of Health Care Workers (HCWs) is mostly based on cross-sectional surveys. We designed a longitudinal study to assess work-related stress and mental health before and after the pandemic onset in a university-hospital in Lombardia region, Italy. We report on sample representativeness and structural validity of questionnaires assessing work stress (HSE Indicator Tool, HSE-IT) and work satisfaction (WS), which were not validated in the HCWs population. n = 1287 HCWs from 67 hospital wards/offices were invited to an online survey in summer 2019 (pre-COVID-19 wave) and again during winter 2020 (COVID-19 wave). Selected hospital wards/offices did not differ from the remaining wards for turn-over and down-sizing rates, overload, sick leaves, and night shifts (Wilcoxon rank tests p-values > 0.05). Participation rates were 70% (n = 805) and 60% (n = 431) in the pre-COVID-19 and COVID-19 waves, respectively. Socio-demographic and work-related characteristics did not impact data completeness nor participation to the COVID-19 wave. While confirming a 7-component structure for HSE-IT, we identified a new factor related to participation in work organization. A one-factor model for WS had satisfactory fit. Our longitudinal study based on a representative sample and adopting validated questionnaires is well-suited to elucidate the role of work conditions on the development of mental health disorders in HCWs.

The North Italian Longitudinal Study Assessing the Mental Health Effects of SARS-CoV-2 Pandemic Health Care Workers-Part II: Structural Validity of Scales Assessing Mental Health.

It is unclear if the factor structure of the questionnaires that were employed by studies addressing the impact of COVID-19 on the mental health of Healthcare Workers (HCW) did not change due to the pandemic. The aim of this study is to assess the factor structure and longitudinal measurement invariance of the Maslach Burnout Inventory (MBI) and the factor structure of the General Health Questionnare-12 (GHQ-12), PTSD Checklist for DSM-5-Short Form (PCL-5-SF), Connor-Davidson Resilience Scale-10 (CD-RISC-10) and Post-Traumatic Growth Inventory-Short Form (PTGI-SF). Out of n = 805 HCWs from a University hospital who responded to a pre-COVID-19 survey, n = 431 were re-assessed after the COVID-19 outbreak. A Confirmatory Factor Analysis (CFA) on the MBI showed adequate fit and good internal consistency only after removal of items 2, 6, 12 and 16. The assumptions of configural and metric longitudinal invariance were met, whereas scalar longitudinal invariance did not hold. CFAs and exploratory bifactor analyses performed using data from the second wave confirmed that the GHQ-12, the PCL-5-SF, the PTGI-SF and the CD-RISC-10 were unidimensional. In conclusion, we found support for a refined version of the MBI. The comparison of mean MBI values in HCWs before and after the pandemic should be interpreted with caution.

Frailty Prevalence, Incidence, and Association with Incident Disability in the Italian Longitudinal Study on Aging

Introduction: Data on frailty frequency are heterogeneous and mostly based on cross-sectional studies. Little is known about frailty development and progression over time. Our aim was to conduct a systematic analysis of frailty prevalence and incidence in a large cohort of older adults and to evaluate the association with incident disability, in order to tackle the current paucity and fragmentation of longitudinal data on frailty. Methods: As secondary analysis of the Italian Longitudinal Study on Aging (ILSA) population-based cohort (n = 5,632, 65–84), frailty status was operationalized according to Fried criteria (n = 2,457). Weighted prevalence and incidence rates were calculated at each ILSA wave (T0 1992–1993, T1 1995–1996, T2 2000–2001). The association with incident disability in Activities of Daily Living (ADL) or Instrumental Activities of Daily Living (IADL) was investigated through Cox proportional hazard models, controlling for possible confounders. Results: Prevalence of frailty and pre-frailty at baseline (mean age 71.6 years; women 58.9%) were 4.0% (95% confidence interval [CI]: 3.4–4.6) and 44.6% (95% CI: 43.1–46.1), respectively. Incidence rates per 1,000 person-years for the T0–T1 interval were 7.3 (95% CI: 5.2–9.3) for frailty and 83.7 (95% CI: 73.6–93.8) for pre-frailty. Prevalence and incidence of frailty, and to a lesser degree of pre-frailty, were overall higher for women and increased with age, yet no increasing trend with advancing age was detected for pre-frailty incidence. Frailty incidence rates were significantly higher among pre-frail than non-frail individuals at follow-up entry. After full adjustment, being frail markedly increased the risk of incident disability in ADL (hazard ratio [HR] 3.58, 95% CI: 1.97–6.52) and IADL (HR 2.56, 95% CI: 1.58–4.16) over a 4-year period. Discussion/Conclusion: According to our findings, frailty is common among older people and is a strong and independent predictor of disability. Further research on factors and characteristics related to frailty progression, and especially remission, over time is crucial to calibrate effective public health preventive measures.

Male and Female Differences in Homicide Mortality: Results of an Italian Longitudinal Study, 2012-2018.

IntroductionItaly has one of the lowest homicide rates in Europe. However, while it is decreasing overall, the proportion of murdered women is increasing. This study aimed to analyze the demographic and socioeconomic characteristics associated with homicide mortality in Italy, focusing specifically on male and female differences.MethodsUsing a longitudinal design, the Italian 2011 General Census population was followed up to 2018. Deaths from homicide were retrieved by a record linkage with the Causes of Death Register. Age-standardized mortality rates, stratified by sex, citizenship, education, and geographic area of residence were calculated. The association between sociodemographic characteristics and homicide mortality was evaluated using quasi-Poisson regression models.ResultsBetween 2012 and 2018, 1,940 homicides were recorded in Italy: 53% were females over age 55, 10% were immigrant females, 34% were males aged 40–54 years, 76% had a medium-low education level, and 57% lived in the South and Islands. Foreign citizenship increased a female's risk of dying from homicide (adjusted rate ratio (RRadj): 1.85; 95% CI: 1.54–2.23), while no differences between Italian and immigrant males were found. An inverse association between education and mortality was observed for both sexes, stronger for males (RRadj: 3.68; 95% CI: 3.10–4.36, low vs. high) than for females (RRadj: 1.38; 95%CI: 1.17–1.62, low vs. high). Moreover, a male residing in the South or the Islands had almost 2.5 times the risk of dying from homicide than a resident in the North-West. Finally, old age (over 75) increased a female's risk of being murdered, whereas the highest risk for males was observed for those aged 25–54 years.ConclusionsMale and female differences in homicide mortality profiles by age were expected, but the results by residence, citizenship, and education highlight that living in disadvantaged socioeconomic contexts increases the risk of dying from homicide, suggesting the need to implement specific prevention and intervention strategies.

The Impact of University-Related Variables on Students’ Perceived Employability and Mental Well-Being: An Italian Longitudinal Study

The COVID-19 outbreak has had a disruptive impact on the academic context and labor market. Indeed, the pandemic shock in such fields has been related to several changes with implications for young people’s careers and well-being. This two-wave longitudinal study, conducted in Italy, aimed to explore the predictiveness of some individual and organizational factors on students’ perceived employability and well-being. A total of 301 Italian students, aged between 18 and 33 (M = 20.63, SD = 1.99), completed a self-report questionnaire measuring career ambition, university reputation, university commitment, technostress related to technology-enhanced learning, perceived employability, and mental well-being at both time points. A path analysis showed that career ambition, university reputation, and organizational commitment positively predicted employability, which, in addition to such variables, positively affected well-being. In contrast, technostress was identified as a risk factor both for students’ perceptions of finding a job and for their well-being. These findings provide a theoretical contribution to a better understanding of the factors involved in undergraduates’ perceived employability and well-being. Moreover, they suggest the need to improve academic-related variables to enhance individuals’ resources in coping with the pandemic challenges.

Occupational physical activity, mortality and CHD events in the Italian Longitudinal Study

PurposeSeveral recent studies have suggested a ‘physical activity paradox’ whereby leisure-time physical activity benefits health, but occupational physical activity is harmful. However, other studies imply that occupational physical activity is beneficial. Using data from a nationally representative Italian sample, we investigate if the context, or domain, of physical activity matters for mortality and coronary heart disease (CHD) events.MethodsAmong 40,220 men and women aged 40–55 at baseline, we used Cox models to compare associations of occupational, domestic and leisure-time physical activity with risk of mortality and CHD events over a follow-up period of up to 14 years. We accounted for sociodemographic factors, smoking, body mass index (BMI), physical and mental health, and educational qualifications.ResultsOccupational physical activity was not significantly associated with risk of mortality or CHD events for women, or with CHD events for men. In crude models, risk of mortality was higher for men in the highest occupational activity group, compared to the lowest (HR 1.26, 95% CI 1.01, 1.57). This attenuated with adjustment for health-related behaviours, health, and education (HR 1.03, 95% CI 0.77, 1.38). In crude models, leisure-time physical activity was significantly associated with decreased mortality and CHD risk only for men. Domestic physical activity was not associated with either outcome for either gender.ConclusionIn a large sample of middle-aged Italian workers, we found limited evidence of harmful or beneficial effects of occupational physical activity on mortality or CHD events. However, confidence intervals were wide, and results consistent with a range of effects in both directions.

Changes in sleep pattern and dream activity across and after the COVID-19 lockdown in Italy: A longitudinal observational study.

SummaryA large body of evidence has documented the impact of the global COVID‐19 outbreak – and especially the lockdown period – on sleep quality and quantity. Here, we present the first Italian longitudinal study on sleep and COVID‐19 considering four different time points collected during lockdown (from 29 March 2020 to 3 May 2020) and a subsequent follow‐up period (October 2020). We used an online survey to collect socio‐demographic and COVID‐19 related information. Subjects were also asked to complete a sleep diary at each time point of the study. Our longitudinal sample included 147 participants. Statistical comparison across time intervals showed remarkable changes in sleep patterns during and after the lockdown. In particular, during lockdown we observed longer sleep latency, less ease of falling asleep, a higher total bedtime, and a lower dream frequency. The week‐by‐week evaluation described relatively stable patterns in the observed measures during the lockdown period, except for dream frequency, affected by a rapid increase in the early phase of lockdown. Our findings are in line with the current literature. Furthermore, the prospective longitudinal investigation comprising several time points offered the possibility of (a) observing the temporal dynamics and the different entities of such changes over time, and (b) reducing the typical memory bias for these studies.

1. Neuropsychiatric disorders and parental stress during the covid-19 pandemic: an Italian retrospective longitudinal study

Aim: The objective of our study is to evaluate the impact that the COVID-19 emergency and the related measures adopted have had on the family management of minors with neuropsychiatric disorders. Another objective of this study is to carry out a first longitudinal evaluation of this impact on parental stress, comparing the data collected before the pandemic with those collected during the lockdown. Methods: This is an observational study that involved 271 families of patients already treated at the Child Neuropsychiatry Unit of the Salerno University Hospital between 2 and 23 years (112 with Autism Spectrum Disorder, 86 with epilepsy and 73 with other disorders of neurodevelopment). All participants were given an ad hoc telephone interview and a standardized questionnaire (PSI - Parenting Stress Index-Short Form). The telephone interview showed that a significant percentage of parents reported an increase in their child's daily management difficulties during the lock-down and emotional / behavioral problems, in particular the externalizing disorder. Comparison of the mean scores of the PSI-SF questionnaires completed before and during the lockdown showed a statistically significant increase in scores in the Total Stress scale and in the Parental Distress subscales. Results &amp; Conclusion: The results of our study suggest that the confinement measures and changes in daily routine imposed by quarantine negatively affected the behavioral and emotional dimensions of both children and parents causing a significant increase in parental stress, which is mainly related to feelings of inadequacy in relation to their role in such a delicate situation, and concern for the future.

Overall Survival in Metastatic Breast Cancer Patients in the Third Millennium: Results of the COSMO Study

IntroductionMetastatic breast cancer (MBC) is a life-threatening disease, and although some data suggest a trend in survival improvement, it has not yet been unequivocally demonstrated. This study aimed to evaluate the overall survival (OS) of MBC patients, assessing its correlation with prognostic factors. Patients and MethodsCOSMO (Checking Overall Survival in a MBC Observational study) is an Italian longitudinal retrospective multicenter study that enrolled patients with MBC diagnosed between 2000 and 2008. The primary objective was to detect a temporal difference in OS; the secondary objective was to identify prognostic factors as causal factors of the temporal variation in OS. ResultsA total of 3721 of 3930 patients from 31 centers were distributed in 3 periods: 886 (23.8%), 1302 (35.0%), and 1533 (41.2%) in 2000-2002, 2003-2005, and 2006-2008, respectively. With a median follow-up of 9.3 years, median OS was 2.8 years (95% confidence interval, 2.6-2.9). No difference in OS was found in the 3 cohorts (P for trend = .563). The worst prognosis was observed for patients with triple-negative MBC (OS, 1.5 years) and for those with central nervous system metastases (1.7 years); the best prognosis was observed in those with bone metastases or nonvisceral disease (3.4 and 3.2 years, respectively) and in patients with a disease-free interval, defined as the time between resection of the primary malignancy and diagnosis of MBC, of > 2 years (3 years). ConclusionsThe COSMO study found improvement in OS between 2000 and 2008. Molecular subtype remained the strongest prognostic factor, and the role of other prognostic factors was confirmed, in particular disease-free interval, site of metastasis, and age.

Towards a national health equity monitoring strategy

Abstract The 2017 Italian Review on health inequalities identified two main needs with regards to Italian health equity monitoring. (1) The need to collect a social covariate at individual level in each health information system at local, regional and national level. Such a social covariate is fundamental for monitoring if any avoidable inequality in access, use, quality of care and health outcome is occurring at local, regional, national level. (2) The need to re-engineer and frame the different health equity monitoring surveys already established into an explicit health inequalities monitoring strategy (HIMS). Both challenges are accounted for by Italy in the Joint Action Health Equity Europe workplan. As for the social covariate, a pilot project is conducted. Data from 2011 census (education and area deprivation) and the national identification code used to link individual data on health and services utilization in four representative regions is linked. This will allow monitoring the social variation in selected performance indicators by region, across regions and through time. As for HIMS, previous research projects have designed and successfully piloted different models of low-cost data linkage for already established longitudinal studies. Now these pilot results will evolve into a national HIMS. As a first step, a special project of consensus building will be implemented among institutional partners responsible for the following national longitudinal studies based on record linkage: a) Work Histories Italian Panel followed up prospectively for health outcomes; b) Italian Longitudinal Study: 2000, 2015, 2013 Health Interview Surveys followed up prospectively for health outcomes; c) differential mortality 2011-2017 in the 2011 censused Italian population; d) the network of the metropolitan and regional census based longitudinal studies followed up prospectively for mortality disease registries and health care utilization. Experiences gained will be shared and discussed.

Life expectancy inequalities and their evolution in Italy. How these impact on the equity of the pension system?

Abstract The article aims to present the most recent evidence on the life-expectancy differentials across socio-economic groups in Italy and discuss their implications in terms of equity and fairness of the pension systems. In fact, Italian pension rules are set according to average life expectancy, ignoring the shorter life expectancy at retirement observed in more disadvantaged socioeconomic groups, as well as in many occupations and economic sectors. This produces unintended consequences in terms of redistribution, which reinforce and exacerbate inequalities present in the labour market. This article will present updated evidence on the evolution of life expectancy inequalities across job titles, sectors and occupational class in Italy to assess whether the social gap, already highlighted by previous scholars, has been widening or narrowing. Only a few studies are available in the literature on this subject, almost exclusively from the US, which suggest that the gap in terms of life expectancy at ages approaching retirement is increasing, mainly driven by a faster improvement in longevity across most advantaged groups. It is crucial to examine the trend in a country like Italy where retirement age has been strongly tightened and linked automatically to average life expectancy in the population. These results may be important in order to inform the public debate about future reforms on retirement rules and in particular for the definition of the so called “arduous and hazardous jobs” (in Italian: lavori gravosi), that could be exempted from the postponement of pension age. In order to estimate life expectancy differentials among different occupations, three of the largest Italian longitudinal studies will be used: the Turin Longitudinal Study (SLT), the Italian Longitudinal Study (SLI) and WHIP-Health Study, all studies where it is possible to conduct mortality follow-up through administrative record linkage with archives of mortality of large cohorts until recent years.

Associations between cardiac arrhythmia, incident disability in activities of daily living and physical performance: the ILSA study.

BackgroundCardiac arrhythmias are common conditions in older people. Unfortunately, there is limited literature on associations between cardiac arrhythmias and physical performance or disability. We therefore aimed to prospectively investigate associations between cardiac arrhythmias and changes in disability and physical performance during 8 years of follow-up, using data from the Italian Longitudinal Study on Aging (ILSA).MethodsCardiac arrhythmias diagnosis was posed through a screening phase, confirmed by a physician. The onset of disability in activities of daily living (ADL) and the changes in several physical performance tests during follow-up were considered as outcomes. Fully-adjusted and propensity-score Cox Proportional Hazard models and mixed models were used for exploring associations between cardiac arrhythmia and the outcomes of interest.ResultsThe prevalence of cardiac arrhythmia at baseline was 23.3%. People reporting cardiac arrhythmia at the baseline were significantly older, more frequently male, smokers and reported a higher presence of all medical conditions investigated (hypertension, heart failure, angina, myocardial infarction, diabetes, stroke), but no difference in dementia, Parkinsonism, cognitive or mood disorder. Cardiac arrhythmia at baseline was significantly associated with the incidence of disability in ADL (HR = 1.23; 95%: CI: 1.01–1.50; P = 0.0478 in propensity score analyses; HR = 1.28; 95% CI: 1.01–1.61; P = 0.0401 in fully adjusted models). Cardiac arrhythmia at baseline was also associated with a significant worsening in balance test (P = 0.0436).ConclusionsThe presence of cardiac arrhythmia at baseline was associated with a significant higher risk of disability and of worsening in some physical performance tests, particularly those relating to balance. Screening and frequently assessing physical performance in older people affected by cardiac arrhythmia can be important to prevent a loss of physical performance, with further, potential, complications of medical management.

Human biomonitoring of metals in workers at the waste-to-energy incinerator of Turin: An Italian longitudinal study.

Evidence of negative health effects of solid waste management is uncertain. Available reviews suggests the use of biomarkers in human biomonitoring (HBM) to detect low exposure levels. In September 2013, a waste-to-energy plant located in the Turin (Italy) went into operation. The SPoTT (acronym for Population health Surveillance in the Turin incinerator's area) monitoring program was set up to assess the potential health impact caused by the plant. The paper illustrates the results of HBM of metals in the workers before the plant went into operation and then at 1 year and 3 years. This study is one of the few focusing on workers with a longitudinal design (the first in Italy). Eighteen metals in urine and lead in blood were determined by sector field inductively coupled plasma mass spectrometry. Information on participant habits and other characteristics that could potentially affect metals concentrations were collected via a structured questionnaire. Subjects were classified according to their work role at the facility: administrative staff workers (AW); plant workers (PW). Nonparametric methods were used to evaluate the changes in metals concentration over time. Comparison of the metals concentration in the samples taken at baseline and at the following two-time points shows a general decrease in levels: urinary concentration of beryllium (Be), cobalt (Co), mercury (Hg), Ir, nickel (Ni), tin (Sn), thallium (Tl), and blood level of lead (Pb) among the PW and Ir and Pd among the AW were significantly lower at T2 versus baseline. A decrease was also recorded in arsenic (As) among the PW and in cadmium (Cd), chromium (Cr), palladium (Pd), rhodium (Rh), and zinc (Zn) for both groups, whereas the levels of copper (Cu) and vanadium (V) remained unchanged over time. The downward trend remained also after taking confounding factors into account. The only exceptions were Mn, Pt, Sb among the PW: increase levels between T0 and T2 were recorded, which cannot be specifically attributable to the plant activity. The median urinary and blood concentrations of the metals were lower than those reported in the literature and were below the occupational reference values at all three-time points. Our results are consistent with those reported for the cohort of local residents and with the ambient air measurements.
