Vaccination against seasonal influenza and socio-economic and environmental factors as determinants of the geographic variation of COVID-19 incidence and mortality in the Italian elderly.
A possible protective effect of seasonal influenza vaccination against the spread of the COVID-19 epidemic has been suggested. ⋯ Extending influenza vaccination coverage particularly among the elderly, vulnerable individuals with specific chronic medical conditions, health care workers, and workers in other essential services, early in the upcoming 2020 influenza season, might help reduce the health impact of a second epidemic wave of COVID-19.

Maternal folic acid supplementation mediates the associations between maternal socioeconomic status and congenital heart diseases in offspring.
Low maternal socioeconomic status (SES) is considered as a risk factor of congenital heart diseases (CHDs) in offspring. However, the pathways underpinning the SES-CHDs associations are unclear. We assessed if first trimester maternal folic acid supplementation (FAS) is a mediator of the SES-CHDs associations. ⋯ In addition, FAS mediated the highest proportion of the associations between income and multiple critical CHDs [46.9%, 95%CI:24.7%,77%] and conotruncal defects [31.5%, 95%CI:17.1%,52.0%], respectively. Maternal FAS partially mediated the SES-CHDs associations, especially among the most critical and common CHDs. Promoting FAS in low SES women of childbearing age may be a feasible intervention to help prevent CHDs.

Medicaid expansion under the Patient Protection and Affordable Care Act (ACA) has the potential to improve reproductive health by allowing low-income women access to healthcare before and early in pregnancy. The aim of this study was to examine the effects of Oregon's Medicaid expansion on timely and adequate prenatal care. We included live births in Oregon from 2012 to 2015 and used individually-linked birth certificate and Medicaid eligibility data. ⋯ Pre-pregnancy Medicaid enrollment increased following Medicaid expansion (β = 0.55, p < 0.001) and was associated with both timely (β = 0.48, p < 0.001) and adequate receipt of prenatal care (β = 0.14, p < 0.001). Using two years of post-ACA data we found that Medicaid expansion had significant positive associations with Medicaid enrollment prior to pregnancy, which subsequently increased receipt of timely and adequate prenatal care. Our study provides evidence that expanding Medicaid has positive effects on women's use of healthcare.

Identifying patterns of movement behaviours in relation to depressive symptoms during adolescence: A latent profile analysis approach.
Movement behaviour guideline adherence has been associated with lower depressive symptoms during adolescence, yet no studies have used person-centered approaches to examine this relationship. The purpose of the present study was to identify whether unique adolescent movement behaviour profiles exist, evaluate predictors of profile membership, and determine whether profile membership was associated with differences in depressive symptoms cross sectionally and longitudinally. This study involved secondary analysis of the public-use data from Wave 1 and Wave 2 of the National Study of Adolescent Health. ⋯ After adjusting for covariates, findings revealed depressive symptoms were lowest among the high MVPA/low ST profile and this trend was evident one year later. Engaging in high levels of either MVPA or ST alone did not provide additive benefits for depressive symptoms compared to those who engaged in low levels of both MVPA and ST. These findings suggest intervention efforts should take an integrative approach to improve mental health outcomes among adolescents by considering each of the movement behaviours concurrently.

Comparative StudyImpact of COVID-19 lockdown policy on homicide, suicide, and motor vehicle deaths in Peru.
Although lockdown measures to stop COVID-19 have direct effects on disease transmission, their impact on violent and accidental deaths remains unknown. Our study aims to assess the early impact of COVID-19 lockdown on violent and accidental deaths in Peru. Based on data from the Peruvian National Death Information System, an interrupted time series analysis was performed to assess the immediate impact and change in the trend of COVID-19 lockdown on external causes of death including homicide, suicide, and traffic accidents. ⋯ The slope in homicide in men during the lock-down period increased by 6.66 deaths per million men per year (95% CI:3.18, 10.15). External deaths presented a sudden drop after the lockdown was implemented and an increase in homicide in men was observed. Falls in mobility have a natural impact on traffic accidents, however, the patterns for suicide and homicide are less intuitive and reveal important characteristics of these events, although we expect all of these changes to be transient.
