Social determinants of adherence to COVID-19 preventive guidelines: a comprehensive review

Adherence to coronavirus disease 2019 (COVID-19) preventive guidelines (ACPG) is an important strategy to control the COVID-19 pandemic effectively. The present study aimed to identify and summarize the social determinants of ACPG among the general population. A comprehensive review was performed from December 2019 to February 2021 through searching electronic databases. Two independent reviewers assessed and selected relevant studies. Next, the characteristics and main findings of the included studies were summarized. Finally, the World Health Organization’s conceptual framework of social determinants of health was used to synthesize the identified social determinants of ACPG. Forty-one of 453 retrieved articles met the inclusion criteria. The study results showed different patterns of ACPG among various communities. Furthermore, 84 social determinants were identified and categorized into structural and intermediary determinants. ACPG is a set of complex behaviors associated with different individual sociodemographic and behavioral characteristics; living and working conditions; COVID-19 knowledge, attitudes, and risk perceptions; exposure to sources and information level; leisure activities; social support; trust; social norms; psychosocial well-being; socio-economic position; and the socio-economic and political context. Interventions to promote ACPG among the general population should consider the identified social determinants of ACPG.

Perceived Stress, Alexithymia, and Psychological Health as Predictors of Sedative Abuse / 가정의학회지

BACKGROUND: The harmful effects of sedative medications and substances in conjunction with limited research regarding predictive psychological constructs of drug abuse necessitate further investigation of associated factors. Therefore, the present study aimed to elucidate the roles of perceived stress, alexithymia, and psychological health as predictors of sedative abuse in medical students. METHODS: In this cross-sectional study, 548 students at Kermanshah University of Medical Sciences, Iran, were selected using stratified random sampling. The data were obtained using the Perceived Stress Scale, an alexithymia scale (Farsi version of the Toronto Alexithymia Scale-20), and a General Health Questionnaire to assess psychological health. Data were analyzed using discriminant analyses. RESULTS: The results demonstrated that the user and non-user of sedative substances groups had significantly different predictive variables (except for social function disorder) (P>0.05). Physical complaints, alexithymia, and perceived stress, which had standard coefficients of 0.80, 0.60, and -0.27, respectively, predicted sedative drug use. CONCLUSION: The results of the present study indicate that perceived stress, alexithymia, physical complaints, anxiety, and depression are associated with sedative drug abuse.

Hepatoprotective effects of hydroalcoholic extract of Allium hirtifolium (Persian shallot) in diabetic rats.

BACKGROUND: The prevalence of diabetes mellitus (DM) is dramatically increasing worldwide. Prospective studies have reported that high levels of hepatic enzymes, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), Alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) are associated with later development of diabetes. The aim of the present study was to examine the effect of hydroalcoholic extract of Allium hirtifolium (Persian shallot) on the level of liver enzymes in streptozotocin (STZ)-induced diabetic rats. METHODS: Thirty-two male rats were divided into four groups of eight. The diabetic groups received 100 and 300 mg/kg Persian shallot extract, the diabetic control and non-diabetic control groups received 0.9% saline for 30 days. At the end of the experimental period, fasting blood samples were collected, and enzymes levels were measured. RESULTS: Our findings showed that hydroalcoholic extract of Persian shallot can significantly decrease serum levels of liver enzymes (AST, ALT, ALP and LDH) in treated groups in a dose-dependent fashion (p<0.05). CONCLUSIONS: Antioxidant micronutrients in the extract of Persian shallot may rehabilitate liver damages caused by free radicals in diabetic rats.
