Precautionary Behaviors during the Second and Third Phases of the COVID-19 Pandemic: Comparative Study in the Latin American Population

The population's behavioral responses to containment and precautionary measures during the COVID-19 pandemic have played a fundamental role in controlling the contagion. A comparative analysis of precautionary behaviors in the region was carried out. A total of 1184 people from Mexico, Colombia, Chile, Cuba, and Guatemala participated through an online survey containing a questionnaire on sociodemographic factors, precautionary behaviors, information about COVID-19, concerns, maintenance of confinement, and medical symptoms associated with COVID-19. Cubans reported the highest scores for information about COVID-19. Colombians reported less frequent usage of precautionary measures (e.g., use of masks), but greater adherence to confinement recommendations in general, in contrast to the low levels of these behaviors in Guatemalans. Chileans reported greater pandemic-related concerns and the highest number of medical symptoms associated with COVID-19. These findings allow a partial characterization of the Latin American population's responses during the second and third phases of the COVID-19 pandemic and highlight the importance of designing and managing public health policies according to the circumstances of each population when facing pandemics.

Patterns of Risk for Multiple Co-Occurring Medical Conditions Replicate Across Distinct Cohorts of Children with Autism Spectrum Disorder

Children with autism spectrum disorder (ASD) may present with multiple medical conditions in addition to ASD symptoms. This study investigated whether there are predictive patterns of medical conditions that co-occur with ASD, which could inform medical evaluation and treatment in ASD, as well as potentially identify etiologically meaningful subgroups. Medical history data were queried in the multiplex family Autism Genetic Resource Exchange (AGRE). Fourteen medical conditions were analyzed. Replication in the Simons Simplex Collection (SSC) was attempted using available medical condition data on gastrointestinal disturbances (GID), sleep problems, allergy and epilepsy. In the AGRE cohort, no discrete clusters emerged among 14 medical conditions. GID and seizures were enriched in unaffected family members, and together with sleep problems, were represented in both AGRE and SSC. Further analysis of these medical conditions identified predictive co-occurring patterns in both samples. For a child with ASD, the presence of GID predicts sleep problems and vice versa, with an approximately 2-fold odds ratio in each direction. These risk patterns were replicated in the SSC sample, and in addition, there was increased risk for seizures and sleep problems to co-occur with GID. In these cohorts, seizure alone was not predictive of the other conditions co-occurring, but behavioral impairments were more severe as the number of co-occurring medical symptoms increased. These findings indicate that interdisciplinary clinical care for children with ASD will benefit from evaluation for specific patterns of medical conditions in the affected child and their family members.

Prevalence and factors associated with the use of alternative (folk) medicine practitioners in 8 countries of the former Soviet Union

BACKGROUND

Research suggests that since the collapse of the Soviet Union there has been a sharp growth in the use of complementary and alternative medicine (CAM) in some former Soviet countries. However, as yet, comparatively little is known about the use of CAM in the countries throughout this region. Against this background, the aim of the current study was to determine the prevalence of using alternative (folk) medicine practitioners in eight countries of the former Soviet Union (fSU) and to examine factors associated with their use.

METHODS

Data were obtained from the Living Conditions, Lifestyles and Health (LLH) survey undertaken in eight former Soviet countries (Armenia, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia and Ukraine) in 2001. In this nationally representative cross-sectional survey, 18428 respondents were asked about how they treated 10 symptoms, with options including the use of alternative (folk) medicine practitioners. Multivariate logistic regression analysis was used to determine the factors associated with the treatment of differing symptoms by such practitioners in these countries.

RESULTS

The prevalence of using an alternative (folk) medicine practitioner for symptom treatment varied widely between countries, ranging from 3.5% in Armenia to 25.0% in Kyrgyzstan. For nearly every symptom, respondents living in rural locations were more likely to use an alternative (folk) medicine practitioner than urban residents. Greater wealth was also associated with using these practitioners, while distrust of doctors played a role in the treatment of some symptoms.

CONCLUSIONS

The widespread use of alternative (folk) medicine practitioners in some fSU countries and the growth of this form of health care provision in the post-Soviet period in conditions of variable licensing and regulation, highlights the urgent need for more research on this phenomenon and its potential effects on population health in the countries in this region.

Randomized controlled trial of mindfulness-based stress reduction delivered to human immunodeficiency virus-positive patients in Iran: effects on CD4⁺ T lymphocyte count and medical and psychological symptoms

OBJECTIVE

To evaluate the immediate and long-term effectiveness of mindfulness-based stress reduction (MBSR) on biological and symptomatological markers of health among human immunodeficiency virus-positive (HIV+) patients in Tehran, Iran.

METHODS

Using a randomized controlled trial design, data from 173 HIV+ patients (CD4 count > 250) not yet receiving antiretroviral therapy, who participated in either an 8-week MBSR (n = 87) or a brief education and support condition (n = 86) at the Imam Khomeini Hospital, were analyzed. Assessments included CD4 count, Symptom Checklist-90-Revised (SCL-90R), and Medical Symptom Checklist (MSCL) at baseline, immediate post-treatment, and at the 3-, 6-, 9-, and 12-month follow-up periods.

RESULTS

The treatment-adherent sample had a mean (standard deviation) age of 35.1 (6.5) years and 69% were male. Linear mixed-model estimates indicated that, in the MBSR condition, the mean CD4 count increased from baseline up to 9 months after treatment and then returned to baseline level at 12 months. Improvements in mean SCL-90R (up to 6 months) and MSCL (up to 12 months) scores were observed for the MBSR condition, whereas education and support condition scores remained the same over time; however, only MSCL improvements significantly differed between groups and these changes lasted up to the final assessment.

CONCLUSIONS

Findings suggest that among treatment-adherent Iranian HIV+ patients not yet receiving antiretroviral drug treatment, MBSR seems to have the strongest potential to improve self-reported medical symptoms.
