Article Synopsis
  • Lead exposure in children significantly hampers cognitive development and future earnings, with a major impact identified in Mexico where traditional studies have been scarce.
  • The study uses national Blood Lead Levels data to calculate economic losses, estimating that cognitive deficits from lead exposure could cost Mexico around $33.02 billion, or 2.76% of its GDP.
  • Findings reveal that children aged 1-4 lose an average of 4.14 IQ points due to lead, with disparities across regions, and poorer states incur greater economic losses relative to their GDP despite having lower blood lead levels.

We conducted a cluster-randomized hybrid effectiveness-implementation study of CyberRwanda, a digital family planning and reproductive health intervention for Rwandan adolescents. Sixty schools were randomized 1:1:1 to control or to one of two implementation models-self-service (self-guided access on tablets) or facilitated (peer-led clubs plus tablet access) with no masking. Eligible participants were aged 12-19 years, in secondary school levels 1 or 2, and willing to provide consent or assent/parental consent and contact information for follow-up.

This study aimed to evaluate the interest in event-driven PrEP (ED-PrEP) among men who have sex with men (MSM) using daily PrEP in Mexico's PrEP demonstration project between 2019 and 2020. We compared participants interested or not in ED-PrEP during their first-month visit and identified associated factors. Of 1,021 MSM attending their first-month visit, 7% had previous knowledge of ED-PrEP, but 40% were interested in ED-PrEP.

Article Synopsis
  • A study in Mexico found that 37% of adults previously diagnosed with COVID-19 reported experiencing Post-COVID conditions (PCC), highlighting a significant public health issue.
  • Common symptoms of PCC included fatigue, muscle pain, respiratory issues, headaches, and cough, with higher prevalence noted among older adults, women, and those with lower socioeconomic status.
  • The findings suggest that addressing PCC is essential for healthcare services in Mexico, although no significant links were found between PCC and conditions like hypertension or diabetes.

The slogan Undetectable equals Untransmittable (U = U) communicates that people living with HIV (PLHIV) who are on antiretroviral therapy (ART) will not transmit HIV to their sexual partners. We describe awareness of U = U among sexual and gender minorities (SGM) living in Brazil, Mexico, and Peru by self-reported HIV status (PLHIV, negative, unknown) during 2021 using an online survey. We estimated two models using Poisson regression for each population group: Model A including socio-demographic factors (country, gender, age, race, education, and income), and then Model B including taking ART (for PLHIV) or risk behavior, ever-taking PrEP, and HIV risk perception (for HIV-negative or of unknown HIV status).

Background Telemedicine, which involves utilising technologies for remote health care delivery, proved useful to continue offering certain health services during the coronavirus disease 2019 (COVID-19) lockdown. However, the extent of its effectiveness in delivering pre-exposure prophylaxis services for HIV prevention remains underexplored from the viewpoint of health care providers. Therefore, this study aimed to assess the experiences of health care professionals in Mexico who utilised telemedicine for delivering pre-exposure prophylaxis services during the COVID-19 contingency.

Introduction: Timely data on HIV service costs are critical for estimating resource needs and allocating funding, but few data exist on the cost of HIV services for key populations (KPs) at higher risk of HIV infection in low- and middle-income countries. We aimed to estimate the total and per contact annual cost of providing comprehensive HIV services to KPs to inform planning and budgeting decisions.

Methods: We collected cost data from the Linkages across the Continuum of HIV Services for Key Populations Affected by HIV (LINKAGES) program in Kenya and Malawi serving female and male sex workers, men who have sex with men, and transgender women.

Background: Lead can affect early childhood development (ECD) differentially due to nutritional deficiencies that lead to stunted growth, defined as being at least two standard deviations below the average height-for-age. These deficiencies are more frequent among children living in rural locations or with lower socioeconomic status (SES); however, studies at a population level are scarce worldwide. Early childhood development plays a crucial role in influencing a child's health and wellbeing throughout life.
