The dual crises of COVID-19 and climate change are impacting the lives of adolescents and young people as they transition to adulthood in an uncertain world, yet they are often excluded from research and political discourse. We surveyed young people about their needs and experiences, critical to engaging them and designing effective programs and policies to address these intersecting harms. The 2022 round of a national online survey through the Violence Outcomes in COVID-19 Epoch (VoCes) Study surveyed 152,088 Mexican youth (15-24 years).

Purpose: Studies have documented diverse adverse effects of the COVID-19 pandemic on young people's lives-for instance on mental health, education/employment prospects, and intrafamily violence. We sought to generate much-needed evidence regarding whether, and which, young people are experiencing multiple intersecting effects.

Methods: Data come from cross-sectional surveys with young people ages 15-25 years in Mexico (nationwide, n = 55,692), Kenya (four counties, n = 2,750), and India (two states, n = 3,537), collected from late 2020 to early 2022.

By 2050, the Global South will contain three-quarters of the world's urban inhabitants, yet no standardized categorizations of urban areas exist. This makes it challenging to compare sub-groups within cities. Sexual and reproductive health and rights (SRHR) are a critical component of ensuring that populations are healthy and productive, yet SRHR outcomes within and across urban settings vary significantly.

Adolescent motherhood has been linked with poor health outcomes at birth for children, including high neonatal mortality, low birthweight, and small-for-gestational-age rates. However, longer-term growth outcomes in the children of adolescent mothers in low-resource settings remain inadequately studied. We used longitudinal data from the India Human Development Surveys, 2004-2005 and 2011-2012 (n = 12,182) and employed regression and propensity score matching analysis to compare the following growth indicators of children born to adolescent mothers (ages 19 years or below) with those born to older mothers.

Background: Survey data that categorizes gender identity in binary terms and conflates sex and gender limits knowledge around the experience of gender minority populations, whose gender identity or expression does not align with the sex they were assigned at birth. In this review, we outline the existing survey research on the experience of a gender minority demographic for whom there is particularly limited data: adolescents and youth in low and middle-income countries (LMICs).

Methods: This paper is a scoping review of peer-reviewed articles, published in English, that use survey data to examine the experience of gender minority adolescents and youth in LMICs.

Nairobi's urban slums are ill equipped to prevent spread of the novel coronavirus disease (COVID-19) due to high population density, multigenerational families in poorly ventilated informal housing, and poor sanitation. Physical distancing policies, curfews, and a citywide lockdown were implemented in March and April 2020 resulting in sharp decreases in movement across the city. However, most people cannot afford to stay home completely (e.

Despite the presence of legal abortion services in Ghana, unsafe abortion remains common, particularly among young women. Little is understood about what young people know about safe and legal abortion, and if and how they are utilizing it. To characterize abortion use and address gaps in safe access, from September-December 2013, we conducted a cross-sectional survey with 100 men and 250 women aged 18-24 in Accra, Ghana.

During a mass media campaign accompanying the launch of the Maximum Diva Woman's Condom (WC) in Lusaka, Zambia, a cluster-randomized evaluation was implemented to measure the added impact of a peer-led interpersonal communication (IPC) intervention on the awareness and uptake of the new female condom (FC). The WC and mass media campaign were introduced simultaneously in 40 urban wards in April 2016; half of the wards were randomly assigned to the treatment (IPC intervention) with cross-sectional surveys conducted before (n = 2,364) and one year after (n = 2,430) the start of the intervention. A pre-specified intention-to-treat (ITT) analysis measured the impact of randomization to IPC at the community level.

Context: In Bangladesh, prior to the availability of the approved combination regimen of mifepristone and misoprostol for menstrual regulation (MR), drug seller provision of misoprostol-only regimens for MR without a prescription was widespread but service quality was poor. Examining provider practices relating to misoprostol-only provision in Bangladesh may increase understanding of misoprostol use and provision in other low-resource, legally restrictive settings.

Methods: In 2013-2014, a countrywide cross-sectional knowledge, attitudes and practice survey was conducted among 777 randomly selected drug sellers; data were analyzed descriptively.

Despite global commitments to achieving gender equality and improving health and wellbeing for all, quantitative data and methods to precisely estimate the effect of gender norms on health inequities are underdeveloped. Nonetheless, existing global, national, and subnational data provide some key opportunities for testing associations between gender norms and health. Using innovative approaches to analysing proxies for gender norms, we generated evidence that gender norms impact the health of women and men across life stages, health sectors, and world regions.
