    The hidden productivity toll of perimenopause: symptom-driven work impairment during women’s peak earning years

    by Yihan Xu, Carley Prentice, Yella Hewings-Martin, Adam Cunningham, Liudmila Zhaunova, Jaume Puig-Junoy

    Perimenopausal women, often in the peak-earning years of their careers, make up a significant proportion of the workforce, with women aged 40-49 accounting for approximately 21% of the U.S. female workforce. Previous studies have revealed perimenopause to be associated with psychological, vasomotor, somatic, and cognitive symptoms that affect women’s quality of life, yet its workplace and economic consequences remain under-explored. We examined work impairment by symptom severity and across reproductive stages in a cross-sectional survey of U.S. women aged 35-59 (n=945), using the Work Productivity and Activity Impairment questionnaire and Menopause Rating Scale. We then estimated associated productivity losses using a human capital approach. Perimenopausal women were equally likely to remain in the labour force as premenopausal women (76.6% vs. 78.0%) but reported substantially higher work impairment (22.5% vs. 12.7%). Work impairment rose from 3.4% among women with minimal symptoms to 33.4% among those with severe symptoms and was driven predominantly by presenteeism rather than absenteeism. Somatic and psychological symptoms showed the strongest associations with work impairment, whereas urogenital symptoms were not significantly associated. The observed work impairment translated into an estimated annual productivity loss of approximately $6,061 per woman in perimenopause and a societal burden of $56.7 billion in the United States. These findings suggest that perimenopause is a substantial but under-recognised workplace health challenge that requires tailored, symptom-matched, workforce support.

  • The Macroeconomic Cost of Obesity and Overweight in European Countries: A Systematic Review and Methodological Quality Analysis

    by Jaume Puig‐Junoy, Judit Guzmán‐Sánchez, Nil Criach‐García, Natàlia Pascual‐Argenté

    Objective: The aim for this study is to systematically review cost‐of‐illness (COI) studies of costs attributable to obesity and overweight (OAO) at the country level for European Union (EU) countries, Northern European countries, the United Kingdom, and Switzerland. Methods: PubMed, Scopus, and HTA Database were searched from 2014 to 2024. This study adhered to PRISMA guidelines. A COI checklist was used to assess methodological quality. Outcome measures were cost as a percentage of GDP and percentage of direct costs. Results: Eight studies were included. Only one study did not use the population attributable fraction approach. Important heterogeneity among studies was observed for BMI categories, for the population age range included, for the range of diseases attributed to OAO, and for the discount rate. Included costs varied among studies, especially indirect costs. More than half of the results for the highest observation for each country, including obesity and overweight global costs, showed results above 2% of GDP (14 out of 26 countries). The results of the regression models showed the decreasing trend of the proportion of GDP attributed to OAO as per capita GDP increases. Conclusions: The majority of studies showed a proportion of costs above 1.5% of GDP; more than half of the 26 European countries showed a cost above 2% of GDP. Total cost at the country level attributed to OAO as a proportion of GDP decreases as GDP per capita increases.

    Differential costs for the non-adult ADHD population in Catalonia

    by Toni Mora, Jaume Puig-Junoy, Rowena Jacobs, Jordi Cid

    Attention-Deficit/Hyperactivity Disorder (ADHD) is young children’s most common mental health disorder. We aim to provide causal estimates of the differential costs for the non-adult population with ADHD. We used longitudinal administrative data covering the non-adult population over five years and different healthcare providers (general practitioners, hospitalisations and emergency departments, visits to mental healthcare centres—day-care or hospitals) of 1,101,215 individuals in Catalonia (Spain). We also include the consumption of pharmaceuticals and cognitive therapies. We instrumented ADHD diagnosis by the probability of being diagnosed by the most visited healthcare provider based on individual monthly visits to the provider in which this visit was related to ADHD and the density of professionals in the different mental health providers. After using matching procedures to include a proper control group, we estimated two-part and finite mixture models. Our results indicate that ADHD children and adolescents displayed 610€ higher annual health direct costs compared to not diagnosed counterparts. We provide average costs disentangling the sample by age boundaries, gender, and comorbidities to offer values for cost-effective analyses and incremental costs after diagnosis, which is around 400€. A significant differential annual direct health cost for the non-adult population with ADHD is determined, which will be helpful for cost-effectiveness analysis and complete cost-of-illness studies.

    Differential Probability in Unmet Healthcare Needs Among Migrants in Four European Countries

    by Hani Fares, Jaime Pinilla Domínguez, Jaume Puig-Junoy

    Migrants and refugees try to reach Europe to seek protection and a better life. The responsiveness and stewardship of the European countries health system have an impact on the ability to access healthcare. This study aims to investigate the differential probability of healthcare unmet needs among migrants living in four European countries. We used a 2019 cross-sectional data from the European Union Income and Living Conditions survey. We performed a two-stage probit model with sample selection, first to identify the respondents with need for care, then those who need it but have not received it. We analysed reasons for unmet needs through accessibility, availability and acceptability. We then performed country studies assessing the national health systems, financing mechanisms and migration policies. Bringing together data on financial hardship and unmet needs reveals that migrants living in Europe have a higher risk of facing unmet healthcare needs compared to native citizens, and affordability of care remains a substantial barrier. Our results showed the country heterogeneity in the differential migrants’ unmet needs according to the place where they live, and this disparity seems attributed to the health system and policies applied. Given the diversity of socioeconomic conditions throughout the European countries, the health of migrants depends to a large degree on the integration and health policies in place. We believe that EU policies should apply further efforts to respect core health and protection ethics and to acknowledge, among others, principles of ‘do-no-harm’, equity and the right to health.

    Inequity and benefit incidence analysis in healthcare use among Syrian refugees in Egypt

    by Hani Fares, Jaume Puig-Junoy

    Background: The Syrian conflict has created the worst humanitarian refugee crisis of our time, with the largest number of people displaced. Many have sought refuge in Egypt, where they are provided with the same access to healthcare services as Egyptian citizens. Nevertheless, in addition to the existing shortcomings of the Egyptian health system, many obstacles specifically limit refugees’ access to healthcare. This study looks to assess equity across levels of care after observing services utilization among the Syrian refugees, and look at the humanitarian dilemma when facing resource allocation and the protection of the most vulnerable.Methods: A cross‐sectional survey was used and collected information related to access and utilization of outpatient and inpatient health services by Syrian refugees living in Egypt. We used concentration index (CI), horizontal inequity (HI) and benefit incidence analysis (BIA) to measure the inequity in the use of healthcare services and distribution of funding. We decomposed inequalities in utilization, using a linear approximation of a probit model to measure the contribution of need, non-need and consumption influential factors.Results: We found pro-rich inequality and horizontal inequity in the probability of refugees’ outpatient and inpatient health services utilization. Overall, poorer population groups have greater healthcare needs, while richer groups use the services more extensively. Decomposition analysis showed that the main contributor to inequality is socioeconomic status, with other elements such as large families, the presence of chronic disease and duration of asylum in Egypt further contributing to inequality. Benefit incidence analysis showed that the net benefit distribution of subsidies of UNHCR for outpatient and inpatient care is also pro-rich, after accounting for out-of-pocket expenditures.Conclusion: Our results show that without equitable subsidies, poor refugees cannot afford healthcare services. To tackle health inequities, UNHCR and organisations will need to adapt programmes to address the social determinants of health, through interventions within many sectors. Our findings contribute to assessments of different levels of accessibility to healthcare services and uncover related sources of inequities that require further attention and advocacy by policymakers.

    The Effect of Changes in Cost Sharing on the Consumption of Prescription and Over-the-Counter Medicines in Catalonia

    by Mario Martínez-Jiménez, Pilar García-Gómez, Jaume Puig-Junoy

    Many universal health care systems have increased the share of the price of medicines paid by the patient to reduce the cost pressure faced after the Great Recession. This paper assesses the impact of cost-sharing changes on the propensity to consume prescription and over-the-counter medicines in Catalonia, a Spanish autonomous community, affected by three new cost-sharing policies implemented in 2012. We applied a quasi-experimental difference-in-difference method using data from 2010 to 2014. These reforms were heterogeneous across different groups of individuals, so we define three intervention groups: (i) middle-income working population—co-insurance rate changed from 40% to 50%; (ii) low/middle-income pensioners—from free full coverage to 10% co-insurance rate; (iii) unemployed individuals without benefits—from 40% co-insurance rate to free full coverage. Our control group was the low-income working population whose co-insurance rate remained unchanged. We estimated the effects on the overall population as well as on the group with long-term care needs. We evaluated the effect of these changes on the propensity to consume prescription or over-the-counter medicines, and explored the heterogeneity effects across seven therapeutic groups of prescription medicines. Our findings showed that, on average, these changes did not significantly change the propensity to consume prescription or over-the-counter medicines. Nonetheless, we observed that the propensity to consume prescription medicines for mental disorders significantly increased among unemployed without benefits, while the consumption of prescribed mental disorders medicines for low/middle-income pensioners with long-term care needs decreased after becoming no longer free. We conclude that the propensity to consume medicines was not affected by the new cost-sharing policies, except for mental disorders. However, our results do not preclude potential changes in the quantity of medicines individuals consume.


  • The impact of taxing sugar-sweetened beverages on cola purchasing in Catalonia: an approach to causal inference with time series cross-sectional data

    by Lluc Puig-Codina, Jaime Pinilla, Jaume Puig-Junoy

    Sugar-sweetened beverage (SSB) taxes related to the quantity of sugar have appeared as a popular regulatory tool around the world during the last decade showing important variations in their implementation and impact. We evaluated the impact of a new SSB tax implemented in Catalonia since May 1, 2017 on the purchased quantities and penetration rates of taxed and untaxed cola beverages. We use aggregate time series of cola beverages purchases in all 17 Spanish Autonomous Communities before and after the implementation of the SBB tax in Catalonia, from January 2013 to June 2019. A comparison between two different types of causal inference methods was conducted: a two-way fixed effects difference in differences model and a modified synthetic control model. Regular cola purchases decreased 12.1% and their penetration rate decreased by 1.27 points during the two post-intervention years using the preferred model. Diet cola purchases increased 17.0% and their penetration rate also increased by 1.65 points. Only regular cola results were robust to all placebo test checks. The SSB tax implemented in Catalonia in 2017 significantly reduced the volume and penetration rates of regular colas with no robust evidence for the substitution effect on diet colas.


  • Free prescriptions for low‐income pensioners? The cost of returning to free‐of‐charge drugs in the Spanish National Health Service

    by Jaume Puig‐Junoy, Jaime Pinilla

    This study estimated the impact of reducing a capped low coinsurance rate for outpatient medicines to nil for low‐income pensioners and disabled individuals in the Valencian Community (Spain). This reduction was implemented in January 2016 as a regional reform which modified the national cost‐sharing reform adopted in July 2012. The impact of this intervention on the number of monthly prescriptions dispensed between July 2012 and December 2018 was estimated using two different approaches of the synthetic control method, the classical method and the method based on Bayesian structural time series. The estimates from both methods were similar, showing significant overall increases of 6.34% and 6.70% [95% credible interval: 4.05, 9.47], respectively in the number of prescriptions dispensed in this region. These results are similar to those of the previous studies indicating that reducing price from a small amount to zero discontinuously boosts demand. This evidence indicates that the impact of this intervention on the budget of the regional health service is far greater than the amount of the subsidy in the public budget. These results are useful for making accurate budgetary projections for similar eliminations of charges for low‐income pensioners in the Spanish National Health Service.

    Effectiveness and cost-effectiveness of Improving clinicians’ diagnostic and communication Skills on Antibiotic prescribing Appropriateness in patients with acute Cough in primary care in CATalonia (the ISAAC-CAT study): study protocol for a cluster randomised controlled trial

    by Rafa Ruiz, Ana Moragas, Marta Trapero-Bertran, Antoni Sisó, Anna Berenguera, Glòria Oliva, Alícia Borràs-Santos, Ana García-Sangenís, Jaume Puig-Junoy, Josep M. Cots, et al.

    Background: Despite their marginal benefit, about 60% of acute lower respiratory tract infections (ALRTIs) are currently treated with antibiotics in Catalonia. This study aims to evaluate the effectiveness and efficiency of a continuous disease-focused intervention (C-reactive protein [CRP]) and an illness-focused intervention (enhancement of communication skills to optimise doctor-patient consultations) on antibiotic prescribing in patients with ALRTIs in Catalan primary care centres. Methods/design: A cluster randomised, factorial, controlled trial aimed at including 20 primary care centres (N = 2940 patients) with patients older than 18 years of age presenting for a first consultation with an ALRTI will be included in the study. Primary care centres will be identified on the basis of socioeconomic data and antibiotic consumption. Centres will be randomly assigned according to hierarchical clustering to any of four trial arms: usual care, CRP testing, enhanced communication skills backed up with patient leaflets, or combined interventions. A cost-effectiveness and cost-utility analysis will be performed from the societal and national healthcare system perspectives, and the time horizon of the analysis will be 1 year. Two qualitative studies (pre- and post-clinical trial) aimed to identify the expectations and concerns of patients with ALRTIs and the barriers and facilitators of each intervention arm will be run. Family doctors and nurses assigned to the interventions will participate in a 2-h training workshop before the inception of the trial and will receive a monthly intervention-tailored training module during the year of the trial period. Primary outcomes will be antibiotic use within the first 6 weeks, duration of moderate to severe cough, and the quality-adjusted life-years. Secondary outcomes will be duration of illness and severity of cough measured using a symptom diary, healthcare re-consultations, hospital admissions, and complications. Healthcare costs will be considered and expressed in 2021 euros (year foreseen to finalise the study) of the current year of the analysis. Univariate and multivariate sensitivity analyses will be carried out. Discussion: The ISAAC-CAT project will contribute to evaluate the effectiveness and efficiency of different strategies for more appropriate antibiotic prescribing that are currently out of the scope of the actual clinical guidelines. Trial registration: ClinicalTrials.gov, NCT03931577.
