AI Article Synopsis
- The study highlights the lack of national statistics on unintentional pregnancy loss in high-income East Asian countries, stressing the need to address income inequality within universal health insurance systems.
- The analysis of National Health Insurance data from 2008 to 2014 revealed a 15% annual average pregnancy loss, with higher rates linked to lower income levels.
- Despite universal health coverage, the research indicates a concerning trend of rising pregnancy loss rates from 2011 onwards, prompting the need for further investigation.
Article Abstract
Background: Although unintentional pregnancy loss is common, national representative statistics are lacking in high-income East Asian countries undergoing rapid demographic changes. It is necessary to confirm the income inequality of pregnancy loss even in universal national health insurance.
Method: Using National Health Insurance Service data between 2008 and 2014, the annual prevalence of pregnancy loss was enumerated, and differences in pregnancy loss according to age and income levels were assessed by multivariable Poisson regression. Joint-point regression was used to examine the trend of pregnancy loss.
Result: On average, there was a 15.0% annual pregnancy loss among 3,941,020 pregnancy cases from 2008 to 2014. Pregnancy loss inequality increased stepwise with income levels except for the highest income group. After adjusting for income levels, the annual percent change of age-standardized prevalence significantly increased by 2.6% every year since 2011.
Conclusion: Even in high-income countries with universal national health insurance, income inequality in pregnancy loss is observed. Further appraisal is needed to explain the increasing trend of pregnancy loss between 2011 and 2014 even after adjusting income.

The transition period is a crucial stage in the reproductive cycle for dams and is linked closely with postpartum recovery, reproduction performance, and health. The confronting problem in the yak industry is that transition yaks under a conventional grazing feeding regime endure nutritional deficiency since this period is in late winter and early spring of the Qinghai-Tibet Plateau with the lack of grass on natural pasture. Therefore, this study aimed to investigate the effects of perinatal nutritional supplementation and early weaning on serum biochemistry, reproductive performance, and metabolomics in transition yaks.

Phthalates are a wide family of chemicals that are used in many different industrial applications used in many different industrial applications, including the production of plastics, toys, food packaging particularly for kids, and medical equipment. Due to their various chemical and physical properties, phthalates may negatively impact humans, animals, and the environment. Thus the potential for phthalate exposure and harm to humans, animals, and the environment is high because its presence is alarming.

Identifying the determinants of pregnancy loss is a critical public health concern. However, pregnancy loss is often not noticed, and even when it is, it is inconsistently recorded. Thus, past studies have been limited to medically-identified losses or small, highly selected cohorts, which can lead to biased or non-generalizable results.
