ABSTRACT
Objectives@#The prevalence of posttraumatic stress disorder (PTSD) has increased, particularly among individuals who have recovered from coronavirus disease 2019 (COVID-19) infection. Health literacy is considered a “social vaccine” that helps people respond effectively to the pandemic. We aimed to investigate the association between long COVID-19 and PTSD, and to examine the modifying role of health literacy in this association. @*Methods@#A cross-sectional study was conducted at 18 hospitals and health centers in Vietnamfrom December 2021 to October 2022. We recruited 4,463 individuals who had recovered from COVID-19 infection for at least 4 weeks. Participants provided information about their sociodemographics, clinical parameters, health-related behaviors, health literacy (usingthe 12-item short-form health literacy scale), long COVID-19 symptoms and PTSD (Impact Event Scale-Revised score of 33 or higher). Logistic regression models were used to examine associations and interactions. @*Results@#Out of the study sample, 55.9% had long COVID-19 symptoms, and 49.6% had PTSD.Individuals with long COVID-19 symptoms had a higher likelihood of PTSD (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.63–2.12; p < 0.001). Higher health literacy was associated with a lower likelihood of PTSD (OR, 0.98; 95% CI, 0.97–0.99; p = 0.001). Compared to those without long COVID-19 symptoms and the lowest health literacy score, those with long COVID-19 symptoms and a 1-point health literacy increment had a 3% lower likelihood of PTSD (OR, 0.97; 95% CI, 0.96–0.99; p = 0.001). @*Conclusion@#Health literacy was found to be a protective factor against PTSD and modified the negative impact of long COVID-19 symptoms on PTSD.
ABSTRACT
The study was carried out in Hoan Kiem and Soc Son District in Hanoi city. In each area, 160 women were selected and divided into 4 groups: The menopause of 5 years, > 5-10 years, >10 years and group of 25- 39 years. Vein blood were taken for measurement of alkaline phosphatase activity and osteocalcin concentration. Hungry urine was collected was to determine urinary calcium and creatinin levels, calcium/creatinin ratio. The results showed that: - Serum osteocalcin and alkaline phosphatase which were biological markers of bone formation significantly increased in menopausal women and then decreased. Urinary calcium level and calcium/creatinin ratio of the Hoan Kiem women were higher than Soc Son ones.
