The dramatic growth in health expenditures is an important health policy concern worldwide. Therefore, understanding the factors that increase health expenditures provides policy makers with evidence for decision-making. We aim to examine long-term effects of carbon dioxide emission, urbanization rate and GDP per capita on health expenditures. This study investigates the effect of carbon dioxide emission, urban population, and GDP per capita on health expenditure for 21 OECD countries over the period 1992–2018. Panel ARDL Approach and Gengenbach, Urbain and Westerlund Panel Co-integration Test have been used in the article. Test results indicate the long-run relationship among health expenditure and carbon dioxide emission, urban population, and GDP per capita. Effect of carbon dioxide emission (CO2), urban population, and GDP per capita is significant and positive on health expenditure. Rapid economic growths of OECD countries recently and environmental pollution have increased health expenditures in the long term. [ABSTRACT FROM AUTHOR]

Introduction: The benefits of completing household chores appear to transfer beyond managing day‐to‐day living. It is possible that chore engagement may improve executive functions, as engagement in chores require individuals to plan, self‐regulate, switch between tasks, and remember instructions. To date, little research has been conducted on household chores and executive functions in children, for whom these skills are still developing. Methods: Parents and guardians (N = 207) of children aged 5–13 years (M = 9.38, SD = 2.15) were asked to complete parent‐report questionnaires on their child's engagement in household chores and their child's executive functioning. Results: Results of the regression model indicated that engagement in self‐care chores (e.g., making self a meal) and family‐care chores (e.g., making someone else a meal) significantly predicted working memory and inhibition, after controlling for the influence of age, gender, and presence or absence of a disability. For families with a pet, there was no significant relationship between engagement in pet‐care chores and executive function skills. Conclusion: We strongly recommend that further research explore the relationship between chores and executive functions. It is possible that parents may be able to facilitate their child's executive function development through encouraging participation in chores, whereas chore‐based interventions (e.g., cooking programmes) may also be used to target deficits in ability.

Background: ‘Paediatric bipolar disorder’ (PBD) is a controversial diagnosis where often prepubertal children as well as adolescents, who may have a range of psychiatric disorders or symptoms, are diagnosed with a severe mental illness requiring lifelong medication. Clinically, it has often been applied in the United States but rarely in most other countries. A meta‐analysis (Van Meter et al., Journal of Clinical Psychiatry, , 72, 1250) claimed that the prevalence of PBD was similar to adults at 1.8% with no difference between the United States and other countries. This conclusion has been highly cited. Methods: The heterogeneous nature of the original 12 epidemiological surveys warrants a qualitative analysis, rather than statistical meta‐analysis as performed by Van Meter et al. (Journal of Clinical Psychiatry, 2011, 72, 1250). Thus, the meta‐analysis and each of the 12 studies (six from the United States; six from other countries) were reexamined. Results: Most of the 12 surveys predated the emergence of the PBD hypothesis. The 12 surveys were mainly of adolescents and at times young adults with few prepubertal children. Prevalence rates in the 12 studies suggest a lower rate of bipolar disorder, especially in non‐US samples. For example, the Van Meter et al. (Journal of Clinical Psychiatry, 2011, 72, 1250) meta‐analysis chose a rate of 2.8% by summation of adolescent and parent responses in a Dutch survey, however the rate fell to 0% if requiring concordance of adolescent and parent responses. Indeed, it could be argued that four of the non‐US studies show 0% rates of PBD. Conclusions: Rates of PBD were generally substantially lower than 1.8%, particularly in non‐US surveys, and if both parent and adolescent reports were required to meet the diagnostic threshold they fell to close to zero. The reanalysis suggests that bipolar disorder is rare before the expected age of onset in later adolescence. [ABSTRACT FROM AUTHOR]
